As a result of this, eutrophication of lakes occurs. Population and economic development are key drivers of water resource pollution. To evaluate how growth in the riparian population and in the gross domestic product (GDP) with unplanned development affects the water quality of the lake, this paper evaluates Lake Victoria Kenyan waters basin. Waters quality data between 1990 and 2012 were analyzed along with reviews of published literature, papers, and reports. The nitrate-nitrogen (NO3-N), soluble phosphorus (PO4-P), chlorophyll a, and Secchi transparencies were evaluated as they are key water quality indicators. The NO3-N increased from 10 μg l(-1) in 1990 to 98 μg 1(-1) in 2008, while PO4-P increased from 4 μg l(-1) in 1990 to 57 μg l(-1) in 2008. The population and economic growth of Kenya are increasing with both having minimums in 1990 of 24.143 million people and 12.18 billion US dollars, to maximums in 2010 of 39.742 million people and 32.163 billion US dollars, respectively. A Secchi transparency is reducing with time, indicating an increasing pollution. This was confirmed by an increase in aquatic vegetation using an analysis of moderate resolution imaging spectroradiometer (MODIS) images of 2000 and 2012 of Kenyan waters. This study found that increasing population and GDP increases pollution discharge thus polluting lakes. One of major factors causing lake water pollution is the unplanned or poor waste management policy and service.

Tropical countries particularly those in the Asian region are at greater risk and vulnerable to the impacts of climate change as indicated by the report of IPCC. With regard to India there are several impacts forecast which could have adverse consequences on the natural resources and ecosystems of the country making them vulnerable and reducing their capacity to cope with a changing climatic regime. This introductory chapter of the book provides an insight to the recent trends, issues and challenges in water resource development in context to the global climate change.

Water resource and supply management systems need to be adaptive to the uncertainty and unpredictability posed by this challenge. The current water crisis is mainly that of governance within the water sector. On this premise, this chapter seeks to explore the adaptiveness of water management institutions and systems to climate change impacts, with a focus on Kenya’s case. Kenya continues to face numerous challenges relating to water supply, which are further exacerbated by climate change. Prior to the development of key legislative and institutional frameworks, through adoption of the Water Act 2002, the water sector grappled with gross mismanagement, manifested via inefficiency in water service provision and resource degradation. Deploying the conceptual model of adaptive (co)-management institutional prescription of polycentric governance, experimentation, public participation, and management of bioregional scale, this chapter stands to contribute novel insights into designing sustainable, adaptive water governance regimes.
