It is a tall stiff glabrous grass with pungent leaves, and a C4 grass with sclerophyllous, spine-tipped, inrolled leaves, with sunken stomata.

Widespread heat waves, floods, and droughts last year were a strong reminder of the threats posed by climate change. In the non-tropical dry areas where ICARDA works we are becoming accustomed to record high temperatures and increasing water scarcity year on year. Resilience and climate change adaptation are at the heart of ICARDA’s new Strategic Plan 2017-2026 – a bold and ambitious effort to harness cutting-edge science and deliver the tools and technologies that smallholder farmers need to maintain agricultural production and protect their livelihoods.

Changes in climate that intensify drought and accelerate the spread of livestock parasites and diseases darken the economic future for sub-Saharan pastoralists. Already stressed, as industrial and urban development narrow their access to pastures and water for their animals, many pastoralists face a bleak choice: abandon their livestock and their cultural heritage or die. In Uganda, however, the outlook for pastoralists is becoming much brighter. Thousands of pastoralists in Uganda point the way toward a better option: commercial milk production.

Index-based livestock insurance (IBLI) is a donor-funded programme aimed at designing, developing and implementing market-mediated, index-based insurance products to protect livestock keepers, particularly in the drought-prone arid and semi-arid lands (ASALs), from drought-related asset losses. The IBLI index is based on satellite data, which measure the quality of the pastureland every 10–16 days. These data are inputs to a statistical model of livestock mortality developed using historical data from the region.
