This chapter focuses on the impacts of climate change on intensive maize and wheat production systems. Some technologies to close the yield gap to achieve sustainable intensification are also discussed.

Achieving and maintaining global food security is challenged by changes in population, income, and climate, among other drivers. Assessing these threats and weighing possible solutions requires a robust multidisciplinary approach. One such approach integrates biophysical modeling with economic mo...

Maize is grown by millions of smallholder farmers in South Asia (SA) under diverse environments. The crop is grown in different seasons in a year with varying exposure to weather extremes, including high temperatures at critical growth stages which are expected to increase with climate change. Th...

Climate variability with unexpected droughts and floods causes serious production losses and worsens food security, especially in Sub-Saharan Africa. This study applies stochastic bioeconomic modeling to analyze smallholder adaptation to climate and price variability in Ethiopia. It uses the agen...

This study uses geo-spatial crop modeling to quantify the biophysical impact of weather extremes. More specifically, the study analyzes the weather extreme which affected maize production in the USA in 2012; it also estimates the effect of a similar weather extreme in 2050, using future climate s...

Maize systems under climate change in sub-Saharan Africa: Potential impacts on production and food security
Climate change is expected to impact global food supply and food security by affecting growing conditions for agricultural production. Process-based dynamic growth models are important tools to estimate crop yields based on minimum inputs of climate, soil, crop management, and crop cultivar param...

This article reviews the published evidence of the climatic risks faced by smallholder farmers in eastern Africa and the adaptation strategies these farmers have so far adopted. In addition, the study draws on two detailed case studies in Kenya for a better understanding of the nuances of climate...
