Identifying loss and waste hotspots and data gaps throughout the wheat and bread lifecycle in the Fars province of Iran through value stream mapping
(2023) Ghaziani, Shahin; Dehbozorgi, Gholamreza; Bakhshoodeh, Mohammad; Doluschitz, Reiner
Reducing wheat and bread loss and waste is crucial for ensuring global food security and sustainability. The importance of reducing wheat and bread loss is particularly significant in Iran, where wheat is a staple crop and a vital component of the country’s food security. A value stream mapping study was conducted to identify loss and waste hotspots and critical data gaps along the wheat and bread lifecycle (WBL). In October 2018, 14 experts were surveyed in Fars province, Iran’s second-largest wheat producer. The study presents a detailed cradle-to-grave overview of WBL and identifies farms, foodservice, and households as the loss and waste hotspots. The results revealed significant data gaps regarding on-farm wheat loss and household bread waste. Additionally, although data exist in other segments of WBL, they are not readily accessible nor utilized to report loss and waste, highlighting the need for transparency within the WBL system and further research to compile existing data and analyze wheat and bread loss and waste. Other researchers can employ the holistic approach of the present study to investigate loss and waste throughout the lifecycle of other food items in different geographical contexts. The methodology adopted in this study offers advantages for defining the scope of research in lifecycle assessment and circular economy studies.
Unraveling on-farm wheat loss in Fars province, Iran: A qualitative analysis and exploration of potential solutions with emphasis on agricultural cooperatives
(2023) Ghaziani, Shahin; Dehbozorgi, Gholamreza; Bakhshoodeh, Mohammad; Doluschitz, Reiner
Given wheat’s global significance as a primary food crop, and its importance in providing essential nutrition to millions of people worldwide, reducing on-farm losses is crucial to promoting food security, sustainable agriculture, and economic stability. Wheat plays a critical role in food security in Iran, as it is a staple food consumed daily by a large proportion of the population, and is also a vital component of the country’s food self-sufficiency policy. The present study aims to identify the causes and extent of on-farm wheat loss in Fars province, a major wheat-producing area in Iran. Nine experts were interviewed, using open-ended questions, in October 2018. The study revealed that a considerable amount of wheat is lost due to seed overuse, pest infestation, and improper harvesting. The paper discusses the underlying factors associated with these over-arching causes, and highlights their adverse environmental, economic, and societal impacts. The paper also explores potential approaches to take in addressing the issue, and suggests empowering agricultural cooperatives through changes in the government’s engagement with wheat production. This study provides valuable insights for policymakers and stakeholders which are useful for developing effective strategies to reduce on-farm loss, particularly in countries where intensified farming is promoted. These strategies may include limiting the government’s central control and, instead, empowering agricultural cooperatives, as well as adopting supportive approaches, such as improving farmers’ access to proper machinery, and enhancing their sovereignty and freedom.
