Heinemann, Alexandre B.Ramírez Villegas, JuliánRebolledo, María CamilaCosta Neto, Germano Martins F.Pereira Castro, Adriano[Upland rice breeding led to increased drought sensitivity in Brazil]Upland rice breeding led to increased drought sensitivity in Brazil

Rice (Oriza sativa) feeds nearly half of the world’s population. Regional and national studies in Asia suggest that rice production will suffer under climate change, but researchers conducted few studies for other parts of the world. This research identifies suitable areas for cultivating irrigat...


Castro-Llanos, FabioHyman, GlennRubiano, J.Ramírez Villegas, JuliánAchicanoy, Harold A.E.[Climate change favors rice production at higher elevations in Colombia]Climate change favors rice production at higher elevations in Colombia

Geoengineering has been proposed to stabilize global temperature, but its impacts on crop production and stability are not fully understood. A few case studies suggest that certain crops are likely to benefit from solar dimming geoengineering, yet we show that geoengineering is projected to have ...


Yang, HuiyiDobbie, StevenRamírez Villegas, JuliánFeng, KuishuangChallinor, Andrew J.Chen, BingGao, YaoLee, LindsayYin, YanSun, LaixiangWatson, JamesKöhler, Ann-KristinFan, TingtingGhosh, Sat[Potential negative consequences of geoengineering on crop production: A study of Indian groundnut]Potential negative consequences of geoengineering on crop production: A study of Indian groundnut

Crop models are used for an increasingly broad range of applications, with a commensurate proliferation of methods. Careful framing of research questions and development of targeted and appropriate methods are therefore increasingly important. In conjunction with the other authors in this special...


Challinor, Andrew J.Müller, ChristophAsseng, SentholdDeva, ChetanNicklin, Kathryn JaneWallach, DanielVanuytrecht, ElineWhitfield, StephenRamírez Villegas, JuliánKöhler, Ann-Kristin[Improving the use of crop models for risk assessment and climate change adaptation]Improving the use of crop models for risk assessment and climate change adaptation

Climate change has been projected to significantly affect agricultural productivity and hence food availability in the coming decades. The uncertainty associated with projecting climate change impacts is a barrier to agricultural adaptation. Despite uncertainty quantification becoming more promin...

Ramírez Villegas, JuliánKöhler, Ann-KristinChallinor, Andrew J.[Assessing uncertainty and complexity in regional-scale crop model simulations]Assessing uncertainty and complexity in regional-scale crop model simulations

Projections of the response of crop yield to climate change at different spatial scales are known to vary. However, understanding of the causes of systematic differences across scale is limited. Here, we hypothesize that heterogeneous cropping intensity is one source of scale dependency. Analysis...
