Like many other African countries described in this volume, Kenya has recently enacted several new policies and public-sector reforms that affect its water sector. This chapter considers those reforms in the context of the country's particular history of land tenure and settlement, a history that continues to have a profound influence on contemporary patterns of land and water management as well as on gender relations in water. The chapter focuses on the particular case of a river basin in Western Kenya, the Nyando river basin (3517 km 2), that has its outlet in Lake Victoria. Over the last century, the Nyando river basin has experienced a history that has shaped spatial patterns of land tenure, settlement and water management. The plural land management systems that exist in the basin today are the product of three distinct periods of historical change: (i) the pre-colonial era that was dominated by customary landholding and land rights systems; (ii) the colonial era in which large areas of land were alienated for specific users and the majority of the Kenyan population confined to native reserve areas; and (iii) the post-colonial era that has encouraged large-scale private ownership of land by men and a small public-sector ownership of irrigation land, all against the backdrop of customary norms and the colonial pattern of settlement and land use. Both colonial and post-colonial institutions have largely disre-garded women's rights to land and water resources. Although customary norms are consistent in ensuring access to water for all members of particular ethnic groups, in practice access and management of water points vary across the basin depending upon the historically defined pattern of landownership and settlement. Customary norms that secure the rights of women to water resources tend to have most impact in former native reserve areas and least impact in ethnically heterogeneous resettlement areas held under leasehold tenure. Recommendations are made on how new policies, legislation and government institutions could be more effec-tive in promoting the water needs of rural communities in Kenya
