This policy brief by the NGOs IIED and Hivos describes how diversification of agriculture and food systems in Zambia can contribute to improving Zambian food and nutrition security, while also building more resilient food systems. It outlines policy recommendations on how the food and agriculture sector can better serve the country’s population through the development of sustainable diets for all.
In this information note from the CGIAR programme on Climate change, Agriculture and Food security (CCAFS), researchers present a rough estimate of the proportion of global agricultural emissions that can be attributed to smallholder farmers in developing countries.
This website published by The International Center for Tropical Agriculture (CIAT), presents interactive visual information and statistics on how food supplies around the world have changed in the past 50 years.
This research brings together data from 389 field trials to determine how the root and shoot biomass, and carbon (C) stocks of major crops correlate to soil C in different environmental conditions. The analysis found all crops allocated more C to their shoots than roots. The greatest C allocation to roots was in grasses (which also had the highest plant biomass production).
This paper in Biological Conservation argues that the role of pesticides in driving biodiversity loss deserves renewed emphasis, quantification and amelioration. The authors present their views on how conservationists should support integrated approaches, for sustainable agriculture and rural development planning, that simultaneously address food security, pesticide use and biodiversity conservation.
This paper, taken from an inaugural edition on planetary health in the Lancet, analyses global food and nutrient production and diversity by farm size, providing evidence on how smallholder farmers contribute to the quantity and quality of our global food supply and discussing the structural impacts of agriculture on nutrient availability.
In this modelling study, the authors examine potential trade-offs between sufficient food provisioning in the future and sustaining biodiversity. On the one hand they find that cropland expansion increases food security, particularly in areas which are currently struggling with access to safe and nutritious food.
As agricultural production of high-yielding cereals has increased over the past half-century, production of more nutrient-rich cereals has declined. Access to food of high nutritional quality is profoundly important, especially for the 2 to 3 billion people who are undernourished, overweight, or obese or deficient in micronutrients.
Alternative cropping systems such as organic or conservation agriculture are often expected to lead to enhanced soil carbon storage as compared with conventional systems, and therefore to hold potential to contribute to climate change mitigation via carbon sequestration.
As much as 75 percent of global seed diversity in staple food crops is held and actively used by a wide range of small farmholders - workers of less than three to seven acres - with the rest in gene banks.
The European Commission was due to publish a Communication on Sustainable Food in 2013 to “assess how best to limit waste throughout the food supply chain, and consider ways to lower the environmental impact of food production and consumption patterns”. This long-awaited Communication has still not been published.
