The region is characterised by whiz wet season, between April-August, followed by a prolonged dry season. Average rainfall varies from 600mm in lowland areas to 1500mm in the highlands. Temperatures range from 16-30c (BDVS, 2005). 1.4 Population The mean density of people is 33.1 per km? (BDVS, 2005). However, this double varies, and most settlements and populations are found near water system resources. 62% of the population dont move over enough food to maintain a healthy living. 1.5 Land use 20,000 Ha of land is apply for cultivation of food and cash crops. However, despite the man-sized size of farmed land, the water supply from rivers and lakes is inadequate to brook domestic, livestock and irrigation needs. 2 Water Provision and Scarcity The WWF (World Wide Fund) states that freshwater is essential to human health, agriculture, diligence and natural ecosystems, b ut is now running scarce in many regions of the world. Figure 2 highlights reasons for new water paucitys. Figure 2 Reasons For Water Shortages Adapted from Sub-sea Infrastructure Report (2006) According to Lomborg (2001), the worlds water consumption has almost quadrupled since 1940. Many experts and environmental agencies including the UN Environmental Report GEO 2000 claim that the water shortage constitutes a full scale emergency, where the world water cycle seems unlikely to be commensurate to cope with increased demands over the coming decades. 3 The Worlds Arid Regions Arid and semi-arid regions go after 30% of the total area (see Figure 3) of the worlds land surface (Balon and Dehnad, 2010) and over 40% of the worlds population live in these areas.

Facilities are also oftentimes polluted by human and animal spoil. For a district that is water-deficient, most of the rainwater that does fall goes to waste due to a lack of appropriate harvesting technologies, especially at household level accord to the Baringo District Vision and Strategy 2005-2015. I aim to highlight how mitigation strategies and water supply management can improve the effectiveness of water resources and provide long-term sustainable solutions. 4.1 Surface Water prehend and Storage There is a need to improve the efficiency of distribution and use of water (Gange, 1965). Kenyas current National Development Plan emphasises the promotion and consumption of rainwater for sustainable development. Non-profit organisations such as Kenya Rainwater Association (KRA) aim to unite communities and bring individuals, institutions, landowners and organisations together to enhance rainwater harvest and utilization techniques. They are currently i nvesting in methods for reducing losses such as evaporation from large storages, seepage from supply channels and other wastage that occurs within the distribution system. Theyve also built roof water tanks for schools that collects and provides safe drinking water. 4.2 Irrigation Agriculture Use of water from the Chemeron Reservoir is a critical issue in Baringo. Current methods of informal basin and channel irrigation involve little monitoring of water application. Modern irrigation
