Abstract
Facing the challenges of global agriculture today: what can we do about drought?
Highlights
According to the latest climate change scenarios, 20-year extreme annual daily maximum temperature will likely increase by about 1–3◦C by mid-21st century, and by about 2–5◦C by the late 21st century, depending on the region and emissions scenario (IPCC, 2012)
Generic facilitating technologies developed by Generation Challenge Programme (GCP) include standardized phenotyping protocols, whole-plant physiology modeling, molecular breeding simulation studies, decision-support tools, procedures for creating low-cost trait diagnostics and high-throughput array-based genotyping systems
Drought tolerance is the main target trait of the Programme, and genomics-assisted breeding for better crop production under water-limited conditions is at the heart of the research supported by GCP during its second phase
Summary
According to the latest climate change scenarios, 20-year extreme annual daily maximum temperature will likely increase by about 1–3◦C by mid-21st century, and by about 2–5◦C by the late 21st century, depending on the region and emissions scenario (IPCC, 2012). As such, improving the drought tolerance of crops, increasing the efficiency of water use and enhancing agricultural water productivity under rain-fed conditions is a number one priority today in a growing number of countries.
