Résumé
The area of Lake Naivasha is of high economic and political importance to Kenya, it presents a wide variety of economic activities around the water resources with many different stakeholders. The analysis and mapping of conflicts related to water in the Lake Naivasha basin could be useful for the existing Management Plan of the lake resources. The objective of the research is to perform a conflict analysis of water-related issues in the catchment area of Lake Naivasha. Essential to the analysis is ?mapping ? the conflicts, which consist in the systematic collection of information about them and their dynamic. The most part of the information was collected through Rapid Rural Appraisal, semi-structured interviews to representatives of the stakeholders within the catchment and existing reports on different subjects affecting water issues. Content analysis was used to analyse and quantify the results of the interviews. The conflict analysis included : analysis of the stakeholders values, research of the conflict sources, definition of a typology of conflicts, and assessment of conflict intensity from the perspective of the different stakeholders developing some indicators. Moreover a visual representation of the conflicts has been attempted through the development of some tentative ?conflict maps ?. The main results have been synthesised in a conceptual model which defines the hierarchy of conflicts related to water within the catchment and the relations between them. The highest in the hierarchy are the conflicts related to the lake resources (fishing), in a second place the water supply of the town and settlements, and in a third place conflicts related to activities taking place in the upper catchment. The conflicts related with water are, most of the times, mixed with other type of land, tribal, social and economic conflicts, and some emotional-historical factors in relation with the inheritance of past colonial times. Physical factors like proximity to water bodies or to forest determine the development of different types of conflicts. Some conflicts are formed by problems not founded on scientific data, as the potential problem of siltation of rivers and lakes, and other problems are more serious than they seem and will intensify some present-day conflicts. For instance, problems of pollution of the lake due to the poor management of the sewage systems of Naivasha town and farms that can seriously affect the lake resources in a close future. It is not possible on a medium and long term to separate the management of the lake and its ecosystem from the management of other water issues and activities within the catchment. The availability of water resources is determined by the behaviour of the hydrological cycle at the catchment level, the alteration of any mechanism or process within the cycle directly or by affecting any of the factors of the hydrological processes will have effects in the quantity and quality of the water resources within the catchment. The water resources of lake Naivasha are tried to be managed in a sustainable way, but other very important aspects of water within the catchment are being ignored or poorly managed, those last ones are having negative effects on the lake. Although the separation of the management of different water issues can be done at certain levels, at a higher hierarchy they converge and an integrated management at the catchment scale is required
