Biophysical and economic implications for agriculture of +1.5° and +2.0°C global warming using AgMIP Coordinated Global and Regional Assessments

Posted by on 2021-12-23

This study presents results of the Agricultural Model Intercomparison and Improvement Project (AgMIP) Coordinated Global and Regional Assessments (CGRA) of +1.5° and +2.0°C global warming above pre-industrial conditions. This first CGRA application provides multi-discipline, multi-scale, and multi-model perspectives to elucidate major challenges for the agricultural sector caused by direct biophysical…

Disability-adjusted life years due to chronic and hidden hunger under food system evolution with climate change and adaptation to 2050

Posted by on 2021-12-23

Climate change presents an increasing challenge for food-nutrition security. Nutrition metrics calculated from quantitative food system projections can help focus policy actions.To estimate future chronic and hidden hunger disability-adjusted life years (DALYs)—due to protein-energy undernutrition and micronutrient deficiencies, respectively—using food systems projections to evaluate the potential impact of climate change…

Future-proof crops: challenges and strategies for climate resilience improvement

Posted by on 2021-12-23

Breeding for stress-resilient crops strongly depends on technological and biological advancements that have provided a wealth of information on genetic variants and their contribution to stress tolerance. In the context of the upcoming challenges for agriculture due to climate change, such as prolonged and/or increased stress intensities, CO2 increase and…

Options for keeping the food system within environmental limits

Posted by on 2021-12-23

The food system is a major driver of climate change, changes in land use, depletion of freshwater resources, and pollution of aquatic and terrestrial ecosystems through excessive nitrogen and phosphorus inputs. Here we show that between 2010 and 2050, as a result of expected changes in population and income levels,…

Determinants of vulnerability of bean growing households to climate variability in Colombia

Posted by on 2021-12-23

Climate variability largely affects agriculture in the developing world where rainfed agriculture is highly prevalent, and farmers rely on favourable climatic conditions to grow their crops. In Colombia, interannual climate variability can increase human vulnerabilities. Evidence on the vulnerability of farming households to climate variability at the local scale is,…

Managing uncertainty: a review of food system scenario analysis and modelling

Posted by on 2021-12-23

Complex socio-ecological systems like the food system are unpredictable, especially to long-term horizons such as 2050. In order to manage this uncertainty, scenario analysis has been used in conjunction with food system models to explore plausible future outcomes. Food system scenarios use a diversity of scenario types and modelling approaches…
