Water is necessary for all human life. It is needed for personal sustenance as well as for agriculture and livestock. Namibia's primarily rural population relies on an adequate source of water for survival. Unfortunately, Namibia's extremely arid climate makes water resources both scarce and valuable. Careful water management is necessary to preserve Namibia's water sources for sustainable, long-term use. In rural and peri-urban areas of developing countries, everyone uses water for various domestic purposes and many people use or could use water for 'productive' purposes to earn an income, such as gardening, field crops, livestock, brick making. Yet in most cases, water sources, uses and users are not well integrated, leaving much scope for improvements in water use efficiency, livelihood, and equitable water use.
