Food Loss and Waste

Globally, about a third of all food is lost or wasted every year. In a world where one in nine people goes hungry, food loss and waste are urgent issues. Reducing food loss and waste can improve food security, nutrition, and smallholder incomes, and potentially reduce agriculture’s contribution to global greenhouse gas emissions.

But data on food loss and waste are scarce. In developing countries, we know little about how much food is lost or wasted and where these losses happen along the value chain—from preharvest losses to consumer waste though poor storage, inefficient supply chains, inadequate infrastructure, and consumer behavior, all stages of the value chain play a role.

To address these knowledge gaps, IFPRI researchers are developing better methodologies to measure food losses and pinpoint where they occur along the value chain. This information is key to designing targeted policies and effective programs for reducing food loss.

IFPRI also evaluates the impact of innovations and technologies for reducing food losses, such as quality-based contractual arrangements, bio-controls for reducing aflatoxin contamination, and appropriate cold storage and transport options for low-income countries.IFPRI’s research on this topic is closely aligned with the Sustainable Development Goals (SDGs), including SDG 2 and SDG 12, and the CGIAR Impact Areas on Nutrition, Health, and Food Security; Poverty Reduction, Livelihoods, and Jobs; and Climate Adaptation and Mitigation.

Resilient Cities urban nutrition profile: Ethiopia

Key Messages -Undernutrition has declined over time, but stunting still affects 40 percent of rural children and 25 percent of urban children. -Micronutrient deficiencies—especially deficiencies in folate, zinc and Vitamin D—are a critical concern, particularly for urban women and girls. -Dietary quality is low in both rural and urban areas: while urban diets are moderately more diverse than rural ones, rising consumption of unhealthy foods is more of a concern than in rural areas at this time. -The cost of consuming a healthy diet in Ethiopia increased from US $2.83 to $3.72 from 2017—2022, and over half of the population is currently unable to afford a healthy diet. -Concurrent conflict and climate shocks are causing acute nutritional needs in some regions. Humanitarian food aid is key to reducing food insecurity and should be provided to households without access to land who rely on income for food purchases, such as those in urban areas. -Overweight and obesity are still uncommon among young children but are increasing rapidly among urban women. In urban areas, 20 percent of women are overweight, compared to 4 percent in rural areas. The rise in urban overweight is driven by lifestyle changes associated with urbanization and unhealthy food environments, which are associated with poor quality diets and reduced physical activity. -Overnutrition and diet-related noncommunicable diseases are especially prevalent in Addis Ababa. -Food safety is a challenge, and evidence is lacking on how to improve vendor safety knowledge and practices to protect consumer health. -National social protection programs often fail to reach the urban poor and lack explicit nutrition interventions in urban areas. -There is a need to design and test urban nutrition interventions that address both over and undernutrition (such as double-duty actions) in urban populations.

Resilient Cities urban nutrition profile: Bangladesh

Resilient Cities urban nutrition profile: Bangladesh

Urban-rural disparities in undernutrition in children under five have dissipated. Stunting declined from 2014 to 2022 in both urban and rural areas, but more so in rural areas, leading to comparable rates of stunting in urban and rural areas (22 percent, 24 percent). Wasting remains “high” (according to the World Health Organization) in both urban and rural areas (11 percent). The prevalence of child overweight is low but increasing, especially in Dhaka. Vitamin A deficiency affects half of children under five. Vitamin D and iron deficiencies are higher in urban areas, with zinc and iodine deficiencies more prevalent in rural areas. Urban and rural diets lack fruits and vegetables. A third of urban households have inadequate caloric intake. The cost of a healthy diet increased from $3.03 to $3.64 per person per day from 2017– 2022 and the percentage of the population unable to afford a healthy diet fell from 65 to 48 percent. Currently, 82 million people are unable to afford a healthy diet in the country. The diet diversity of young children has improved since 2011, but gains were seen mostly in rural areas. The percentage of all children fed the minimum meal frequency dropped by 20 percentage points from 2017 to 2022. Urban informal settlements are a concern – children have higher rates of stunting, lower dietary diversity, and higher prevalence of micronutrient deficiencies compared to other urban children. Overweight and obesity in urban adults is a critical problem. More urban women (48 percent) are overweight compared to rural women (35 percent); the same is true for urban men (29 percent) compared to 17 percent for rural men. Some urban nutrition interventions to tackle child undernutrition are being implemented, but few have been rigorously evaluated. Data on urban food environments (FEs) is becoming more available, but there are gaps in knowledge, particularly on the design and evaluation of interventions to counter the influence of the country’s increasingly obesogenic urban FE. National policies include targeted actions to improve urban diets and nutrition. More could be done, however, to improve the healthiness and safety of FEs, leverage social protection programs for the urban poor to make healthy diets more affordable, and to implement double-duty actions to address all forms of malnutrition.

Improving resource targeting in Niger: Joint financial analysis and food system mapping

Improving resource targeting in Niger: Joint financial analysis and food system mapping

This policy brief combines the results of a food system mapping exercise with an analysis of financial flows into Niger’s food system from 2019 to 2022 to inform policymaking for food system transformation. The food system mapping reveals several critical points of failure, from low agricultural productivity and inefficient supply chains to poor nutritional outcomes and environmental degradation. Analysis of domestic and international financial flows to the food system reveals that climate adaptation and nutrition are underfunded areas. Understanding these weaknesses can help policymakers and development partners take a more coordinated and strategic approach to addressing the challenges facing Niger’s food system and can inform more effective resource allocation, ensuring that resources support long-term food security and sustainability.

How vegetables can stay for 30 days without spoilage (The Guardian)

The Guardian (Nigeria) published an article on food spoilage. Food spoilage, which is the loss of food meant for human consumption due to inefficiency along the food supply chains, reduces the net availability of food for human consumption. Lack of food, because of spoilage, intensifies poverty, hunger, and malnutrition.  IFPRI estimates that a 10 percent reduction in […]
