TL;DR: A global model finds that the environmental impacts of the food system could increase by 60–90% by 2050, and that dietary changes, improvements in technologies and management, and reductions in food loss and waste will all be needed to mitigate these impacts.

TL;DR: In this article, a robust yield gap analysis for 10 countries in sub-Saharan Africa using location-specific data and a spatial upscaling approach reveals that, in addition to yield gap closure, other more complex and uncertain components of intensification are also needed, i.e., increasing cropping intensity and sustainable expansion of irrigated production area.

Journal ArticleDOI
Land Tenure and the Adoption of Conservation Practices
TL;DR: In this paper, the influence of land tenure on the adoption of conservation practices was analyzed by distinguishing renters according to lease type and by distinguishing practices according to the timing of costs and returns.
Journal ArticleDOI
Health and nutritional aspects of sustainable diet strategies and their association with environmental impacts: a global modelling analysis with country-level detail
Marco Springmann,Keith Wiebe,Daniel Mason-D'Croz,Daniel Mason-D'Croz,Timothy B. Sulser,Mike Rayner,Peter Scarborough +6 more
TL;DR: This global modelling analysis combined analyses of nutrient levels, diet-related and weight-related chronic disease mortality, and environmental impacts for more than 150 countries in three sets of diet scenarios found that energy-balanced, low-meat dietary patterns that are in line with available evidence on healthy eating led to an adequate nutrient supply for most nutrients.
