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.

Conservation agriculture (CA) has been proposed as an adapted set of management principles that assures a more sustainable agricultural production. It combines the following basic principles: (1) reduction in tillage, (2) retention of adequate levels of crop residues and soil surface cover, (3) u...

Conservation agriculture as a means to mitigate and adapt to climate change, a case study from Mexico
Soaring international food and energy prices and the resulting volatility in markets is alarming many African policy makers. The domestic production of wheat in many countries suffers from lack of policy support and donor neglect resulting from the perception that Africa cannot competitively prod...

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...

The world population is projected to increase to 9–10 billion by 2050, during which time it will be necessary to reduce anthropogenic greenhouse gas emissions to mitigate climate change. The particular challenge this places on agriculture is to identify practices which ensure stable and productiv...

Highly Pathogenic Avian Influenza (HPAI) is a major threat to the poultry industry worldwide. In developing countries backyard poultry production is often an important livelihood activity for women who use the additional income for unexpected household expenses. The disease can therefore have sig...
