    2011 was the first year of operation of the CGIAR Research Program on Climate Change, Agriculture and Food Security (CCAFS). CCAFS brings together the work of all 15 international Centres in the CGIAR, and is a joint programme between the CGIAR and the Earth System Science Partnership (ESSP). 2011 was a start-up year in terms of introducing a new way of working across Centres, but it was also a year of considerable research effort. Work was initiated in the field at many sites, and baseline surveys were completed in three regions on two continents.

    Low water use efficiency is a challenge to crop production in Sub-Sahara African countries. Water is getting continuously scarce due to increased demand and shrinking availability induced mainly by climate change. As agriculture is the major consumer of water, improving crop water productivity is among the ways of overcoming the challenge. Crop production under rainfed system is the major livelihood strategy for smallholder farmers in Ethiopia.

    Ecosystem integrity as well as the goods and services offered by the rivers in India are getting adversely affected by changes in quantity quality and flow regimes. Growing water abstractions for agriculture domestic industrial and energy use are leaving many rivers running dry while others are becoming severely polluted. The mighty Ganga is no exception. During its 2,525 km journey from Gangotri to Ganga Sagar there are complex, nested sets of challenges that threaten the very existence of the holy river revered by millions of Indians.

    This study was conducted at Ginchi watershed in Oromia Regional State, Ethiopia to evaluate the
    physical, chemical and microbiological quality of livestock drinking waters during dry, short rain and wet
    seasons. Purposive sampling technique was used to obtain samples. Data were collected and analyzed using
    descriptive statistics. The analysis showed that the overall mean concentrations (mg/l) were 298.33 TDS, 8.0

    Kenya, África, África oriental

    Use and retention of river water in African highlands deprive communities in arid lowlands of their benefits. This paper reviews information on water use in the Ewaso Ng’iro catchment, Kenya, to evaluate the effects of upstream abstraction on the Lorian Swamp, a wetland used by pastoralists downstream. We first assess the abstractions and demands for water upstream and the river water supplies at the upper and the lower end of the Lorian Swamp.

    A survey was undertaken to understand sheep management, breeding practices and selection criteria for Red Maasai sheep in Maasai pastoralist communities in Kajiado District, Kenya. Differences between North and South Kajiado District were investigated to gain knowledge about farmers having different prerequisites and how it can affect the sheep production. The reason for keeping sheep and the specific breeds show the multiple objectives of the Maasai farmers.
