These two studies discuss afforestation projects in relation to 1) land availability and sheep farming in Scotland, and 2) the biodiversity losses that may be associated with such projects.

The OneHealth project, launched in 2015, explores the relationship between infectious diseases, biodiversity and ecosystems, the economics of disease and disease drivers, and the impacts of climate change and demography on health.

In parts of the world such as sub-Saharan Africa, significant agricultural expansion into natural ecosystems is predictable and likely unavoidable. This study presents a newly developed modelling tool, designed to provide quantitative answers to problem of how agricultural expansion could be located in ways that meet agricultural production goals, but which incur substantially lower losses of carbon and biodiversity than conventional agricultural development pathways.

Two of the greatest current challenges are climate change (and variability) and food security. Feeding nine billion people by 2050 will require major efforts aimed at climate change adaptation and mitigation.

This study warns that converting Africa's tropical forests into monoculture palm plantations will cause a significant spike in carbon emissions and highlights that regulation can assist in achieving net-zero carbon while meeting production goals.

This report aims to understand whether, why and how sustainable diets are promoted by individual foodservice companies, and to assess the business cases for adopting and promoting sustainable diets across the sector.

As the climate changes, and food demand increases, crop varieties suited to these conditions need to be developed. The authors of this paper warn that crops yields around the world could fall within a decade unless action is taken to speed up the introduction of new varieties. They propose three ways to improve matching of maize varieties in Africa to a warmed climate: reduce the BDA (the process of breeding, delivery and adoption), breed under elevated temperatures and act to mitigate climate change.

119 countries pledged to reduce their GHG emissions in the 2015 Paris Agreement but exactly how much mitigation is needed by each sector to meet the 2-degree global target still largely unknown. This paper by Wollenberg et al., provides an estimate of how much GHG mitigation should be expected of the agricultural sector; compares this with what current plausible mitigation options could deliver – and finds a major discrepancy between the two.

This paper looks at how soil can help contribute to climate mitigation.  It argues that by decreasing greenhouse gas emissions, sequestering carbon and using prudent agricultural management practices that improve the soil-nitrogen cycle (tighter cycle with less leakage), it is possible to enhance soil fertility, bolster crop productivity, improve soil biodiversity, and reduce erosion, runoff and water pollution.
