An analysis of gender in intra-household decision-making as an important socio-economic factor in agriculture-nutrition linkages
(2021) Sariyev, Orkhan; Zeller, Manfred
In 2018, almost 2 billion people around the globe experienced severe or moderate levels of food insecurity. Poverty is strongly linked with food insecurity, and most of the extreme poor live in rural areas where agriculture is the main livelihood. Thus, agricultural and rural development have profound implications for rural households. Agricultural produce is consumed or marketed or both; when marketed, the generated income can be used for (safe and nutritious) food purchases and non-food expenditures, including medical expenses and investments in sanitation. Some income may not be consumed directly but saved or invested in the form of physical, social or human capital. Moreover, considering that the end goal of development should be an environment in which people can be creative and freely enjoy a long and healthy life, rural and agricultural development will have implications for all elements of human development: health, education, poverty, environment, security, women’s status, and finally, food and nutrition. The effect is seemingly more direct and profound in terms of its contribution to a healthy household environment and food security, which together determine nutritional outcomes. However, this seemingly straightforward linkage between agriculture and nutrition is challenged by numerous socio-economic factors. This dissertation concentrates on the gender dynamics of intra-household decision-making as an important socio-economic factor in the agriculture and nutrition framework. Here, I refer to gender dynamics as the interactions and relations between men and women that can strengthen or confront the social norms of a society. Thus, the main objective is to examine the gender dynamics of decision-making as an important component of agriculture-nutrition linkages. There are three sub-objectives that concentrate on selected linkages within the framework. Given the high concentration of women’s empowerment literature in social contexts in which females are underprivileged, the first sub-objective is to investigate the implications of women’s empowerment in contexts in which women historically experienced equality or favoritism. Second, concentrating on the role of women’s empowerment in the agriculture and nutrition framework, the next objective is to study the implications of women’s empowerment on varietal adoption, diversified production, and consumption. The third objective is to examine the viability of production diversification as a strategy to improve household diets. The findings of this dissertation are based on data collected from Bhutanese and Ethiopian households. The survey in Bhutan employed multistage random sampling; it was implemented in November 2017 and covered 251 households in two central districts of Bhutan: Tsirang and Dagana. The survey in Ethiopia was conducted in 2014 and 2016 and covered 390 Ethiopian households located in a radius of circa 150-200 km around the town of Hawassa. These households were randomly selected from a sample of farmers from a survey that was conducted by the International Food Policy Research Institute (IFPRI) for the Ethiopian Agricultural Transformation Agency (ATA) in 2012. This dissertation has five chapters. The first chapter gives a general overview and provides a conceptual framework that helps to describe the research topics and questions investigated in the following chapters. The three following chapters are scientific papers that have been prepared for publication in scientific journals. The second chapter deals with the first sub-objective. It investigates women’s participation in crucial domains of intra-household decision-making and its implications for dietary quality in Bhutanese households. The third chapter studies the effect of the main female’s risk preference on the adoption of high-yielding varieties (HYVs) conditional on the dominance of female preferences declared in domestic decision-making. The fourth chapter explores the association between women’s participation in decision-making and both agricultural production and dietary diversity. The final chapter concludes the dissertation, highlights main limitations, and gives recommendations for future research and policies. Chapter 1 discusses the agriculture-nutrition linkages and interacting socio-economic factors of interest in the conceptual framework of the dissertation. Chapter 2 investigates the implications of women’s participation in domestic decision-making processes for dietary quality in Bhutanese rural households. Bhutan was selected as the country of interest for this chapter because polyandry and matrilineal succession were still observed in some ethnic groups through the 20th century. We employ a mixed methods research approach to investigate women’s participation in domestic decision-making processes and its implications for dietary quality at the household level. Considering the historical presence of matrilineal succession in Bhutan, we also check for any association between women’s land ownership and participation in domestic decision-making using non-parametric tests. Quantitative analyses and in-depth interviews reveal no lack of participation in crucial domains of domestic decision-making for Bhutanese women. We observe a positive association between women’s participation in decision-making and their property rights; thus, it is plausible that the matrilineal succession might have provided for women’s empowerment over time. Moreover, we find that gender equality in decision-making results in better dietary diversity in Bhutanese households. Given the results, we recommend that social programs focus not merely on women’s empowerment, but gender-equal human development in general. The findings contribute to the gender literature and emphasize the importance of gender equality. Considering that females are generally found to be more risk averse than males and that risk aversion hinders technology adoption, in Chapter 3, we study the importance of the main female decision-maker’s risk preference for the adoption of HYVs in Ethiopia. Most often, food security is the ultimate goal for the rural poor in Ethiopia. Their risk preferences are likely to determine their willingness to trade some short-term security for a greater potential income and security in the future. Rural households are disinclined to adopt new varieties as they are unfamiliar and present a risk of failure. The number of female decision-makers in a household is assumed to reflect the dominance of female preference declared in household decision-making. The main female decision-maker is assumed to be empowered to express her preferences more strongly and freely when the decision-making processes involves more female members. In this case, the impact of her risk preferences is likely to be more profound. To the best of my knowledge, this hypothesis has not been investigated before. Considering that rural households are constrained differently, we want to study both adoption and intensity of the HYV adoption. The results show no effect of the main female’s or male’s risk preferences on the adoption of HYV seeds. It is observed that the adoption decision is mostly determined by access and availability, which are captured by wealth, access to extension, and all-weather roads. We observe a positive association between the main female’s risk preference and the intensity of the adoption at higher levels of women’s participation in decision-making. As hypothesized, the conditionality of the effect of female risk preference on the level of female dominance in decision-making is observed. Given these results, we conclude that the main female’s risk preference matters for the intensity of HYV adoption. Given the potential risk of crop failure when adopting HYV, a risk-taking female is willing to risk her household’s short-run security to a potential learning effect from the new variety and potentially gain a higher income and more security in the long-run. The findings from this chapter contribute to the gender and technology adoption literature. The study interacts female risk preference with a proxy that measures female dominance in decision-making in an HYV adoption study. The results of our analysis of the role of the main female’s risk preferences in agricultural technology adoption signify the importance of a gendered lens to intra-household decision-making and risk preferences for future empirical studies. Nutrition sensitive agricultural development programs consider diversified farm production as a promising strategy to achieve better dietary outcomes for rural poor who are mostly subsistence oriented. In Chapter 4, we mainly question the viability of this strategy for rural Ethiopian households. Furthermore, considering that both household-level production diversification and consumption choices are outcomes of intra-household decision-making, we investigate the implications of women’s participation in the domains of decision-making for both outcomes. Thus, there are two objectives in Chapter 4. The first is to estimate the association between production diversification and household dietary diversity in various settings, and the second is to examine the association of female participation in decision-making with both livelihood outcomes separately. We find that on-farm diversification can be a feasible strategy to improve the diets of those who are mostly subsistence oriented and therefore highly dependent on agricultural production and those who live a great distance from markets. These results were obtained by employing and carefully interpreting multiplicative interaction models. We find that women’s participation in decision-making regarding which crops are grown is associated with more diversity both in terms of food groups and the number of different livestock and crop species produced. Nevertheless, we do not find any association when both evenness and richness of crop species are considered together as an indicator of diversification. This is due to the fact that sampled Ethiopian women are observed to be involved in decision-making on small plots, such as kitchen gardens, which contribute to the richness of species but not to the evenness in terms of the cultivated area. Furthermore, we estimate a positive association between women’s decision-making regarding household expenditures (that include food, clothing, and household and agricultural assets) and dietary diversity indicators. In light of these results, we conclude that development programs could promote production diversification in remote rural areas where markets and non-farm income are hardly accessible, but even then, the viability of this strategy is very questionable due to the marginal effects that demand mostly unrealistic changes. We recommend that more attention and effort be directed toward gender-inclusive social and economic development policies together with infrastructural and market development projects to achieve sustainable returns to nutrition. We contribute to the agriculture and nutrition literature by highlighting an important covariate, that is gendered decision-making, and calling attention to an in-depth approach to the analyses of this kind to better assist practitioners. Overall, the main contribution of this dissertation is that the gender dynamics in intra-household decision-making is an important socio-economic factor in the agriculture and nutrition framework. The findings prove that gender sensitive policies and programs will contribute to this component and sustain the linkages between agriculture and nutrition in rural areas. It is observed that women’s empowerment in farming and household-related decision-making positively contributes to various components like varietal adoption, diversification, and household-level dietary diversity in the agriculture and nutrition framework. However, extensive contextual knowledge is necessary to ensure that gender bias is correctly approached and treated to yield positive and sustainable outcomes in different societal settings.
Analysis of factors driving differences in intensification and income from agriculture among smallholder farmers in Northern Vietnam
(2021) Ufer, Susanne; Zeller, Manfred
Challenged by difficult topography, remoteness, high ethnic diversity, low levels of infrastructure, high poverty, and high dependency on upland farming systems the well-being and incomes of ethnic minorities and the poorest in the Northern Uplands of Vietnam, like in many upland areas in Southeast Asia, are still predominantly linked to agricultural productivity. At the same time agricultural commercialization, the introduction of modern agricultural technologies, higher input use, and stronger agricultural specialization have increased the demands on households’ ability to adequately invest in agricultural intensification and to protect themselves from agricultural income risks. In the Northern Uplands, one of these extensively cultivated, highly commercialized, and highly specialized upland crops is maize. A crop that needs high levels of inputs and is predominantly grown for cash income from poor and non-poor farmers alike. Given the low asset levels of households, it is therefore of particular interest which differences in challenges farmers may face regarding the improvement of maize production dependent on their wealth level. Yet, no detailed research exists that analyses how the level of asset endowments with natural, human, physical, financial, and social capital as well as risk aversion impact technology adoption, maize intensification, and maize productivity of farmers of different household wealth. This doctoral thesis seeks to fill these knowledge gaps by investigating the following research topics: (1) the level and short-term changes in agricultural input use and productivity in maize production by household wealth, (2) the impact of risk aversion on fertiliser use in maize production by household wealth, and (3) the impact of household asset levels and the return to assets on productivity differences in maize production between households of different wealth. Research analysis builds on a quantitative dataset collected from a random panel sample of 300 rural households in Yen Chau district, Son La province, in the Northern Uplands of Vietnam in the period from 2007 to 2010. The research area is relatively poor, ethnic diverse, with a high dependency on upland agriculture, crop income, and maize income in particular. Econometric analysis is carried out firstly by organizing households by wealth through a composite asset-based indicator derived from principal component analysis (PCA) and secondly by applying extensive descriptive analysis, regression analysis, and econometric decomposition-based techniques to the so differentiated dataset. Results from the first research topic (1) “Level and short-term changes in agricultural input use and productivity in maize production by household wealth” show that average numbers on maize input use, maize productivity, and maize income hide important wealth-related differences. While adoption rates of modern maize seeds and mineral fertilisers are widespread and very similar by wealth terciles over time, input use intensity of fertilisers, maize yields, and maize incomes differ significantly between the poorest tercile and the wealthier maize farmers. While a substantial share of the poorest household tercile uses fertiliser quantities well below recommended levels, households of the middle and wealthiest terciles are about twice as likely to apply fertilisers according to average or above-average fertiliser recommendation levels. Moreover, between approximately one-tenth and one-quarter of households from all wealth terciles overuse fertiliser, too. The poorest tercile further buys despite the lower use of fertilisers more often seed and fertiliser inputs on-loan than households from higher wealth terciles. Consequently, the poorest households have to pay relatively higher input costs at otherwise mostly similar market prices for seed and fertiliser inputs and maize output. Yield, input price, and output price risks are high in the research area for all households. However, the poorest tercile of households suffers somewhat more from risks due to fluctuations in yield, output price, and maize income. Results from the second research topic (2) “Impact of risk aversion on fertiliser use by household wealth” show that the fertiliser quantity applied to maize is affected by the risk aversion of the household head in the poorest one-third of households and not affected by the risk aversion of the household head of the wealthier households. The results remain valid when different empirical risk aversion measures (i.e. self-assessment scale and lottery game) are considered, when instead of total fertiliser quantity, the quantity of NPK, urea, or total nitrogen are considered, as well as when different measures of household wealth are considered (i.e. asset-based wealth index, household per-capita income, and household per-capita consumption expenditure). Results from the third research topic (3): “Impact of household asset levels and the return to assets on productivity differences in maize production between households of different wealth” show that quantity-based assets effects are more important for the size of the maize income gap per hectare between the poorest one-third of maize farmers and maize farmers of higher wealth than the return-based assets effects. Quantity-based asset effects significantly account for more than two-thirds of the entire maize income gap, while return-based assets effects are on the contrary not statistically significant at all. From the quantity-based assets effects, credit limit, ethnicity of the household head, and upland land value have large and significant effects. Farm size, value of buffalo and cattle, and household head age have smaller and less constant effects. Credit limit is the most important and most consistent driver by size, showing that financial access for poor minority households is still a defining obstacle to agricultural productivity. Ethnicity of the household head has a strong and positive but decreasing impact on the maize income gap, showing that ethnicity-related soft factors, such as differences in location, agricultural practices, and traditions, should be taken more into acknowledgement. From the significance of the upland land value, we conclude that environmental factors, such as the prevention of soil erosion, the protection of soil fertility, and considerations of long-term sustainability, should gain more emphasis. Other minor factors driving the maize income gap are discussed in more detail in the thesis. From the results of the doctoral thesis, we draw the following main conclusions for the development of pro-poor strategies for the improvement of upland agricultural productivity. Firstly, agricultural research and extension should pay more attention to identifying bottlenecks households face dependent on their wealth level to avoid overseeing the specific obstacles poor and non-poor farmers face that may result in the perpetuation of poverty traps, increased inefficiency, and the waste of resources. Consequently, more emphasis is needed on research and extension that incorporate wealth-related agronomic, financial, and risk-related aspects, that better account for the efficient use of inputs, and that place increased emphasis on the adaptation of technological innovations to the farm systems and needs of upland minorities. Secondly, more emphasis should be placed on helping poor households to deal with risks. While all households face yield, input and output price risks, risk aversion affects input intensification decisions in the poorest one-third of households. Hence, especially for the poorest more emphasis should be placed on the expansion of risk management options that account for the lower risk-bearing capacity and higher risk aversion of the poor, and the often higher transaction costs. This includes measures such as improving the financial literacy of households, allowing households to borrow for consumption, linking credit with insurance or saving options, decreasing transaction costs and the complications linked with successfully applying for loans, as well as, if possible, developing innovations like improved seeds or agricultural management systems that have the capacity to lower the downside risks of production. Thirdly, assets should be considered an important driver of agricultural productivity differences between poor and non-poor farmers. Based on the findings that the quantity-based effects of assets are the major and only significant driver of the maize income gap between the poor and non-poor maize farmers, we conclude that the poorest households can have the same productive agricultural potential as the non-poor if they would have the same level of assets. Supporting households to get access to and accumulate assets should be therefore an important policy goal. This is particularly true about assets that can be influenced by agricultural research, improved agricultural extension, and targeted development policy. Based on our research findings this concerns the improvement of access to credit, the support of ethnic minority households, and efforts to increase the sustainability of upland agriculture. Fourthly, investing in the long-term suitability of maize production and upland farming systems is recommended. While maize can be a very profitable cash crop in the short run, the results of this doctoral thesis also show that a strong specialization in maize production may embody multiple short-term and long-term economic as well as sustainability related livelihood risks. This includes the possibly limited extent of the profitability of additional credit and inputs as well as a strong dependency on the quality of natural resources. In consequence, policies should focus on directly improving the conditions for maize productivity as well as improving the conditions for long-term development. Such measures include supporting households to invest more in profitable on-farm and off-farm diversification, the improvement of infrastructure and extension to increase the profitability of unused cropping choices, the development of profitable soil protection measures, and investments in education and the development of off-farm job alternatives.
Debt position of developing countries and new initiatives for debt reduction: a panel data fixed effects estimation of the impacts of the HIPC initiatives
(2005) Houssou, Nazaire; Heidhues, Franz
In September 1996, the World Bank and the International Monetary Fund launched the Heavily Indebted Poor Countries Initiative (HIPC). This initiative was endorsed by 180 governments around the world as an effective and welcome approach to help poor, severely indebted countries reduce debt as a part of the overall poverty reduction strategy. Three years later, the initiative was enhanced to provide for faster, broader and deeper debt relief. Using a panel data fixed effect estimation, this study assesses the achievements of the first and second HIPC initiatives and explores further areas of intervention that might help the HIPCs graduate from debt rescheduling and achieve sustainable growth and poverty alleviation. Despite moderate achievements of the HIPC measures so far, this paper argues in favour of a HIPC III initiative. Much more relief is needed to link debt reduction to poverty alleviation if the expectations raised by the HIPC initiatives are to become reality.
Institutional change in Cuba's agricultural sector
(2010) Jaffe Lopez, Mercedes Isabel; Zeller, Manfred
Cuba has a low agricultural production and depends on costly food imports. The partial reforms advanced by the government during the 1990s seem to have failed in increasing productivity or output. Due to a lack of primary research in the agricultural sector, little is known about the incentives and constraints that producers face. This dissertation seeks to contribute in the reduction of this knowledge gap and proposes a new way of understanding the transition in the agricultural sector in Cuba. The role of the institutions governing this sector is studied in order to evaluate the main problems of different producer types and the possibilities and constraints of reform towards a more productive agriculture. The dissertation is organized around three papers. The analyses presented in these papers use quantitative and qualitative data collected during two field trips in 2007-2008 and 2009, as well as secondary data from publications, news and official statistics. The first paper describes the sector?s institutional framework and compares the performance of different producer types that include state farms, semi-independent collectives, and private producers. These producers differ in their access to illegal markets, and in their property rights for land and cattle. Private farmers have more incentives to produce due to their stronger user rights, resulting in a better productive performance when compared to state and state-dependent collective farms. The results cast doubt on the prevailing idea that production problems result from technical or resources deficiencies. The second paper deals with the largest producer type described in the first paper, by exploring poverty and food access of collective farm households with the use of principal component analysis and other methods. It is found that relative poverty and food security depend on the household?s access to individual and collective resources for subsistence production. The main productive activities and the economic performance of the state-dependent collective farms have no correlation with the poverty status of their workers, exposing incentive problems at worker level. The third paper investigates the constraints that have led to the failure of adopting economically efficient institutions by evaluating the historical political power dynamics in Cuba?s agricultural sector. It is found that the institutions adopted aim to limit the accumulation of political power by private producers. Economic crises that threaten the political elite have caused the partial and temporary adoption of free markets and the distribution of state land to private farmers. These reforms, however, have been blocked by the bureaucrats as they lose political power. The papers show that the incomplete and insecure property rights regime in Cuba results in low overall productivity caused by incentive and other problems. In the case of the state-dependent collective farms, this increases the poverty and food insecurity of the workers, while hurting the supply of rationed food to the general population. The institutional setup is a result of power dynamics where the elite, using the bureaucracy, tries to minimize the political threat of organized private producers by limiting their accumulation of wealth. Successful reform of the agricultural sector would require a redefinition of the power bases and relationships between the government and political stakeholders such as the bureaucracy and other groups (for example the civic society) by allowing participation of these stakeholders in the shaping of the reforms. The dissertation concludes by presenting an outlook for research and the international development organizations working in the country.
Opportunities and constraints for agrofuels in developing countries : case studies on economic viability and employment effects of Jatropha production
(2010) Grass, Martin; Zeller, Manfred
This dissertation was motivated by controversial statements of politicians and lobby groups for and against first-generation agrofuel production. Therefore this thesis contributes to a more realistic view on opportunities and constraints for agrofuel production based on first-generation technologies. The findings are based on an intensive literature review covering the following topics: current production trends of ethanol and agrodiesel, their potential for fossil energy substitution and greenhouse gas reduction including related costs, rural development and poverty alleviation. This more general overview on agrofuels was deepened by own research on Jatropha seed production in India and Madagascar. In this context the economic viability of Jatropha seed production and possible income effects for households living in the vicinity of a Jatropha plantation were analyzed. For this special agrofuel feedstock the findings allowed shedding some light on important aspects of the much broader topic concerning the production of agrofuels. To cover the above mentioned topics this dissertation is structured around three research papers. The first paper identifies and discusses the opportunities and constraints of first-generation agrofuel production in developed and developing countries and is based on an intensive literature review. Therefore this paper contrasts arguments used by politicians to justify agrofuel support measures like energy security, greenhouse gas reduction potential, income generation and possible rural development with new scientific findings on each argument. Furthermore data on worldwide trends in ethanol and agrodiesel production were presented. The second paper focuses on one possible option to lower competition between food and agrofuel production at least partially. This option is seen in the production of Jatropha seeds on marginal land not suitable for food production. In this context an Indian case study revealed the economic viability of Jatropha seed production on marginal land. The database for this study includes data derived from literature as well as experimental field data provided by the ?International Crops Research Institute for the Semi-Arid Tropics?. The third paper addresses possible income effects for rural households offering their labour force to a Jatropha plantation in central Madagascar. The econometric impact assessment is based on a socio-economic household survey undertaken by the author in 2009. To account for possible selection bias the propensity score matching approach was used to estimate the average treatment effect on the treated by comparing the average income of Jatropha plantation households and control households. The findings for 336 households reveal positive income effects for households working at the Jatropha plantation. The dissertation concludes that more investments in research are needed to gain a potential win-win situation for rural households, investors and the environment especially for the case of developing countries. The results lead to the conclusion, that smallholder based Jatropha seed production should not be promoted in developing countries. Therefore this dissertation concludes further that it would be far better for developing countries to let international investors set up Jatropha plantations, hence in this case the economic risk is borne by the foreign investors. Furthermore abundant labour in rural areas could find employment opportunities with such plantations and therefore would be able to generate some income for their families. Nevertheless the implementation of Jatropha projects financed by international investor?s needs regulations set up by national governments. Those regulations should cover each aspect within the entire value chain of Jatropha agrofuel production and should be embedded in a national energy and rural development policy. Furthermore institutional frameworks such as land tenure security and labour rights have to be enforced. Setting up aforementioned regulations and institutional frameworks can prevent possible constraints such as, land grabbing, exploitation of rural labourers, loss of biodiversity and competition between Jatropha seed and food production e.g. for scarce water, which could occur due to foreign investment in local Jatropha (and other agrofuel feedstocks) cultivation in the worst case.
Payments for environmental services : incentives through carbon sequestration compensation for cocoa-based agroforestry systems in Central Sulawesi, Indonesia
(2008) Zeller, Manfred; Seeberg-Elverfeldt, Christina; Schwarze, Stefan
Up to 25 percent of all anthropogenic greenhouse gas emissions are caused by deforestation, and Indonesia is the third largest greenhouse gas emitter worldwide due to land use change and deforestation. On the island of Sulawesi in the vicinity of the Lore Lindu National Park (LLNP), many smallholders contribute to conversion processes at the forest margin as a result of their agricultural practices. Specifically the area dedicated to cocoa plantations has increased from zero (1979) to nearly 18,000 hectares (2001). Some of these plots have been established inside the 220,000 hectares of the LLNP. An intensification process is observed with a consequent reduction of the shade tree density. This study assesses which impact carbon sequestration payments for forest management systems have on the prevailing land use systems. Additionally, the level of incentives is determined which motivates farmers to desist from further deforestation and land use intensification activities. Household behaviour and resource allocation is analysed with a comparative static linear programming model. As these models prove to be a reliable tool for policy analysis, the output can indicate the adjustments in resource allocation and land use shifts when introducing compensation payments. The data was collected in a household survey in six villages around the LLNP. Four household categories are identified according to their dominant agroforestry systems. These range from low intensity management with a high degree of shading to highly intensified shade free systems. At the plot level, the payments from carbon sequestration are the highest for the full shade cocoa agroforestry system, but with low carbon prices of ? 5 tCO2e-1 these constitute 5 percent of the cocoa gross margin. Focusing on the household level, however, an increase of up to 18 percent of the total gross margin can be realised. Furthermore, for differentiated carbon prices up to ? 32 tCO2e-1 the majority of the households have an incentive to adopt the more sustainable shade intensive agroforestry system. A win-win situation seems to appear, whereby, when targeting only the shade intensive agroforestry systems with carbon payments, the poorest households economically benefit the most and land use systems with high environmental benefits are promoted.
Targeting of and outreach to the poor by rural development nonprofit organizations in Cameroon
(2010) Balgah, Azibo Roland; Buchenrieder, Gertrud
The importance of nonprofit organizations such as rural development organizations, farmers associations and common initiative groups as drivers of change in rural areas has been generally recognized in the economics of nonprofit organizations. While the economic theories attempt to explain the formation and functioning of nonprofit organizations, the targeting and outreach performance of these organizations has received little attention and at best is empirically divergent. Using the example of a nonprofit rural development organization in North West Cameroon, this paper analyzes the relative poverty of beneficiaries and non beneficiaries of its small scale fish farming program as a proxy for targeting efficiency. Poverty is measured through multiple indicators as well as household incomes. The results show that the nonprofit organization did a commendable job in serving poor communities, although its self targeting approach led to a disproportionately higher share of beneficiaries from the moderately poor and better-off terciles than from the poorest. Beneficiaries also had higher asset values and incomes than nonbeneficiaries, although the contribution of the fish farming activity to these was insignificant. This means that these households were already better-off prior to the program and not necessarily as a consequence of service delivery. The paper concludes with the need for relative poverty assessments prior to service delivery for improved targeting and outreach performance, while considering the additional costs involved.
The dietary quality of food pantry users from a socio-ecological perspective
(2019) Simmet, Anja; Ströbele-Benschop, Nanette
In Germany, around 1.5 Mio people with a low income receive food for a small fee from one of around 940 so-called “Tafel”. In high-income countries like Germany, users of food pantries are a particularly vulnerable population group, as they are characterized by cumulative health risks. They often suffer from food insecurity and from chronic diseases such as hypertension, diabetes mellitus type 2 or obesity. Given that these diseases as well as food insecurity both relate to diet, the dietary quality plays a critical role in the health status of food pantry users. To illustrate the dietary quality and the different levels of factors influencing the dietary quality among food pantry users, this thesis has the following aims: 1. to provide a summary of the scientific evidence about the dietary quality of food pantry users in high-income countries; 2. to provide a summary of the scientific evidence about the nutritional quality of food provided by food pantries in high-income countries; 3. to examine the distribution of Tafel food pantries and food banks and to provide a representative picture of their resources (e.g. food, volunteers etc.), activities (e.g. provided programs) and users in Germany; 4. to examine the distribution of Tafel food pantries and to identify compositional and physical environmental correlates of food pantry use in Berlin. To reach these aims, two systematic reviews were conducted (first and second publication). In addition, an explorative cross-sectional study consisting of an analysis of secondary data and a comprehensive survey among all Tafel belonging to the federal association “Tafel Deutschland” was performed (third publication). Finally, an ecological study was conducted by analyzing and mapping food pantry use and compositional and physical characteristics of areas in Berlin (fourth publication). The first review revealed that the dietary quality among the reviewed food pantry users tended to be low as reflected by an inadequate intake of energy, fruit and vegetables, dairy products and calcium compared to national recommendations. The reviewed food pantry users had, in particular, a lower consumption of dairy products compared to the general populations. The second review demonstrated that the nutritional quality of reviewed pre-packed food bags provided by food pantries was highly variable within and between included studies. It also showed that the nutritional quality of most of the food bags was low, reflected, in particular, by a low provision of dairy products, vitamins A and C and calcium compared to national recommendations. None of the studies included in the reviews were nationally representative. The third publication showed that the German food bank system Tafel Deutschland provided a comprehensive net of food pantries, social supermarkets, food banks and other services. However, the number of Tafel per 10,000 welfare recipients was lower in eastern Germany (M = 1.37) compared to western Germany ((M = 2.12), t(162.54) = 4.2424, p < 0.0001). In contrast to the results of the studies included in the second review, the Tafel mainly provided perishable food such as fruits and vegetables (41.42% of the amount of food distributed), bakery products (19.85%) and dairy products (13.39%). However, due to the dependence on donors such as retailers, the amount of food distributed varied widely. The assistance of most local Tafel is based on volunteer labor as 89.97% of Tafel’s staff were volunteers. In 79 districts, in which all Tafel participated in the survey, there was an average of 179 Tafel beneficiaries per 1000 welfare recipients and 17 Tafel beneficiaries per 1000 residents overall. An even lower usage was found by the fourth publication which revealed that only two out of 1000 adult inhabitants and six out of 1000 children received assistance from one of the 44 investigated Tafel food pantries in Berlin. Tafel use by adults (A) or by children (B) was related to the percentage of welfare recipients (A, β = 0.17, p < 0.001 und B, β = 0.16, p = 0.002), the percentage of inhabitants with migration background (A, β = - 0.08, p = 0.002), the number of discount grocery percentage stores per 1000 children (B, β = 5.65, p = 0.010), and the number of stops of the public transport within a radius of 500 meters (A, β = - 0.24, p = 0.020). The most important limitation of both studies was the unknown reliability of the data collected from the Tafel. The dietary quality of food pantry users in high-income countries was seen to be low. Although food pantries did not provide a full meal plan for a healthy diet, they may have a positive impact on the dietary quality of its users. However, to better understand the role of food pantries in the complex interplay of individual, social and environmental influences on the diet of food pantry users, multi-level approaches should be used in the future. Moreover, researchers are strongly recommended to investigate the mechanisms by which using a food pantry might impact users’ dietary quality. In addition to these implications for researchers, this thesis makes several recommendations to practitioners at food pantries in Germany and other high-income countries. Following these recommendations could make the position of food pantries in civil society into an important entry point for health promotion among a part of the food insecure population in the future.
The impact of agricultural innovations on poverty, vulnerability and resilience to food insecurity of smallholders in Ethiopia

Ethiopia has adopted agriculture centered growth strategies over the last three decades that give more emphasis on improving agricultural production and productivity with the ultimate goal to transform the country’s economy. The strategies have mainly aimed at improving smallholder agriculture through introducing improved technologies intended to boost agricultural production and thus alleviate poverty and food insecurity. Although agriculture centered growth strategies contributed to sustained growth in the country over the last two decades, the benefits of growth have not been evenly distributed with observed rising income inequality and a still significant proportion of smallholders remaining under the poverty line. Similarly, despite considerable yield progress over the last three decades due to the introduction of improved inputs Ethiopian farmers’ yield gap compared with other developing countries is quite high. Moreover, the frequent occurrences of shocks such as drought and flooding adversely affect smallholders substantially and thereby exacerbate the existing poverty and food insecurity problems in the country. This thesis applied different econometric techniques to analyze the impact of the adoption of multiple agricultural technologies on crop yield, poverty, vulnerability, and resilience to food insecurity in Ethiopia. The study uses four rounds of household level panel data collected between 2012 and 2019 to assess the link between the adoption of the different combinations of five productivity-enhancing technologies: chemical fertilizer, improved seed, pesticide, and soil and water conservation practices: terracing and contour ploughing on consumption, poverty, vulnerability, and yields of smallholders. To solve the endogeneity problem in the regression models, we applied two-stage multinomial endogenous switching regression model combined with the Mundlak approach. Additionally, the thesis examines the role of the adoption of chemical fertilizer and improved seeds on household resilience to food insecurity amid the occurrence of adverse shocks. The findings are presented in three chapters of the cumulative thesis (Chapters two to four). Chapter two analyses the effect of productivity enhancing technologies and soil and water conservation measures and their possible combinations on consumption, poverty, and vulnerability to poverty. Per capita consumption expenditure for food and other essential non-food items, such as clothing and footwear, is used as a proxy variable to measure poverty. Using the national poverty line in 2011 prices, sample households are grouped into poor and non-poor households and the movement of sample households in and out of poverty between 2012 and 2016 is analyzed using a poverty transition matrix. By employing the ordered logit model, the study additionally examined the dynamics of poverty and vulnerability as well as their drivers. The results show that the adoption of the different combinations of agricultural technology sets including single technology adoption has considerable impacts on consumption expenditure and the greatest impact is attained when farmers combine multiple complementary inputs. Similarly, we find that the likelihood of households remaining poor or vulnerable decreased with adoption. In addition, the study revealed that poorer households are the least adopters of the technology combinations considered in the study, thereby being the least to benefit from adoption. We, therefore, conclude that the adoption of multiple complementary technologies has substantial dynamic benefits that improve the poverty and vulnerability status of households, and given the observed low level of adoption rates, we suggest that much more intervention is warranted, with a special focus on poorer and vulnerable households, to ensure smallholders get support to improve their input use. Chapter three assesses the impacts of multiple technology adoption on the yield of Ethiopia’s four staple crops, namely teff, wheat, maize and barley. Regarding the empirical estimation, we specified yield equations for each of the four crops and five to six possible input combinations that are included in the analysis indicating the presence of slope effect of technology choice other than the intercept of the outcome equations. The findings suggest that the application of two or more complementary inputs is considerably linked with higher maize, teff, barley, and wheat yield. Specifically, barley yield is highest for farmers who have adopted a combination of at least three of the technologies. Maize producers are the largest beneficiaries of the technologies. The impact of the technology choice sets tends to have an inconclusive effect on wheat and teff yields. However, a significant yield gap in all of the four crops was observed. Socio-economic characteristics of the household head such as age and gender as well as the household’s access to infrastructure and spatial characteristics of the household are other important determinants of crop yield. The implications are that more publicly funded efforts could be worthwhile for easing adoption constraints, which would in turn help smallholders to increase their crop yields that indirectly improve their livelihood. Chapter four aims to identify the determinants of household resilience to food insecurity which is the household’s ability to absorb or cope with the negative effects of shocks and bounce back to at least their initial livelihood status and assess its role on future household food security when hit by adverse shocks. Furthermore, the study analyzes the role of single or joint adoption of chemical fertilizer and improved seed on household food security. The household food security indicators used in the analysis are dietary diversity and per capita food consumption and uses data from the last three waves out of our four survey rounds. In terms of empirical estimation, the household resilience capacity index is estimated by combining factor analysis and structural equation modeling. Then different regression models are executed to assess the causal link between technology adoption and resilience capacity and household food security indicators in the face of adverse shocks. Our findings reveal that the most important pillars contributing to the building of household resilience capacity are assets followed by access to basic services. We find that the initial level of the household resilience score is significantly and positively associated with future household food security status. Moreover, the results reveal that the adoption of chemical fertilizer and improved seed is significantly and positively associated with household resilience capacity index, dietary diversity, and food consumption over time. Shocks such as drought appear to be significant contributors to the loss of household food security. Overall, it is revealed that the adoption of improved inputs significantly and positively increases household food security. However, the results show no evidence that supports the current level of adoption that helps households to shield themselves from the adverse effects of shocks. Finally, this study gives insights on examining the impacts and impact pathways of adoption of improved technologies on smallholder welfare which guide decision-makers for intervention as well as pave a way for future research that contributes to the fight against rural poverty and food insecurity. This thesis also concludes that public intervention in terms of investment in providing improved agricultural practices is crucial in improving rural livelihood, but it has to be inclusive and provide opportunities for the poor and vulnerable.
Use of household food insecurity scales for assessing poverty in Bangladesh and Uganda
(2008) Alcarez V., Gabriela; Zeller, Manfred
An important dimension of poverty is access to food. Household food security implies access to the food needed for a healthy and productive life. Lack of access to and/or impaired utilization of food contribute to household food insecurity. This study compares the usefulness of a standardized food insecurity scale for determining the food insecurity status of rural and urban households in Bangladesh and Uganda, and for predicting poverty status. The analysis uses data from the IRIS Composite Survey Household Questionnaire (2004), which consists of 1,587 households (approximately 800 households in each country). The coping mechanisms adopted in the presence of food shortages represent the building blocks for the development of the scale (7 items). In order to assess the suitability of the scale as an estimator of the households? poverty status, the benchmark indicator ?daily expenditures per capita? and its relation to the corresponding poverty line serves as the basis for evaluation for each country. The scale provides the means for classifying the households into 3 main groups: Non Food Insecure, Moderately Food Insecure, and Severely Food Insecure. The reliability of the scale is measured via the Cronbach?s Alpha statistic. In addition, the scale is used in regression analysis in order to predict per capita daily expenditures and the poverty incidence. The results show that food insecurity does not always reflect (income) poverty. However, the use of the scale as a predictor of poverty status produces rough estimates of poverty incidence that could be useful as background information. The differentiation of households according to their food security status may be valuable for focusing and developing improved food insecurity mitigation strategies.
