- One CGIAR and the Integrated Agri-food Systems Initiative: from short-termism to transformation of the world's food systems(Public Library of Science, 2021) Govaerts, B.; Negra, C.; Camacho Villa, T.C.; Chavez, X.; Diaz Espinosa, A.; Fonteyne, S.; Gardeazabal, A.; González, G.; Singh, R.G.; Kommerell, V.; Kropff, W.; Lopez-Saavedra, V.; Mena-Lopez, G.; Odjo, S.; Palacios-Rojas, N.; Ramirez-Villegas, J.; Van Loon, J.; Vega, D.; Verhulst, N.; Woltering, L.; Jahn, M.; Kropff, Martinus

Publication - Importance of considering technology growth in impact assessments of climate change on agriculture(Elsevier, 2019) Aggarwal, P.K.; Vyas, S.; Thornton, P.; Campbell, B.M.; Kropff, MartinusMany assessments of climate change impacts on global crop yields project declines as early as the 2020s. Losses are projected to increase with time, up to 50% by the 2080s. We carry out a systematic global review and compare published projections of climate change impacts from 34 studies and ∼4500 data points for the 2020s for maize, rice and wheat at country level with observed and forecasted national crop yields for the same period based on available global crop statistics. We find that observed yield changes are considerably higher than projected yield changes arising from climate change because technological improvements appear to have a large yield-enhancing impact compared with the negative effects of climate change, at least in the short term. Most assessments of climate change impacts on crop yields show low-latitude, low and middle-income countries as highly vulnerable but these countries have shown the largest growth in observed yields over the same reference time period. These discrepancies are due to incomplete consideration of technological growth in climate impact assessments and large yield gaps in these countries, uncertainties associated with the methodologies used, and regional variations in adaptation options considered. Appropriate consideration of technological growth can add considerable value and relevance to global impact assessments, contributing to investment and development targeting at both large and small scales.

Publication - Borlaug Institute of South Asia(CIMMYT, 2018) Kropff, Martinus; Joshi, A.K.; Chandiramani, M.Borlaug Institute of South Asia (BISA) is an international research institute established in October 2011 at New Delhi, through a joint initiative between International Maize and Wheat Improvement Centre (CIMMYT) and the Indian Council of Agricultural Research (ICAR) to implement the vision of Norman E. Borlaug. By adopting the ‘Agricultural Research for Development’ approach, BISA aims to invigorate the agriculture and food systems in the region, make it climate resilient while enhancing productivity, livelihood and nutrition security of millions of people.
Publication - Improving global integration of crop research(American Association for the Advancement of Science, 2017) Reynolds, M.P.; Braun, H.J.; Cavalieri, A.J.; Chapotin, S.M.; Davies, W.; Ellul, P.; Feuillet, C.; Govaerts, B.; Kropff, Martinus; Lucas, H.; Nelson, J.M.; Powell, W.; Quilligan, E.; Rosegrant, M.W.; Singh, R.P.; Sonder, K.; Tang, H.; Visscher, S.; Wang, R.R.C.In recent decades, the scientific, development, and farm communities have contributed to substantial gains in crop productivity, including in many less developed countries (LDCs) (1), yet current yield trends and agri-food systems are inadequate to match projected demand (2). Addressing transnational crop challenges will require refinement of research infrastructure and better leverage of global expertise and technologies. Drawing on lessons learned from international collaboration in wheat, we outline how such a model could evolve into a Global Crop Improvement Network (GCIN) encompassing most staple food crops, providing access to well-controlled “field laboratories,” while harmonizing research practices and sharing data. Combined with socioeconomic and cropping systems research, a GCIN could revolutionize the ability to understand and model crop responses to environments globally and accelerate adoption of vital technologies.
