effects <strong>of</strong> supporting various commercial enterprises while creating dem<strong>and</strong> for locallyproduced goods <strong>and</strong> services.The two prime tourist attractions for Kenya <strong>and</strong> Tanzania are tied to the ability <strong>of</strong> the<strong>Mara</strong> River Basin to provide sufficient water to keep the animals within the protectedareas. The dem<strong>and</strong> for water continues to increase in the upper <strong>and</strong> middle zones <strong>of</strong> theriver basin <strong>and</strong> is therefore likely to affect the downstream wildlife sanctuaries <strong>of</strong> <strong>Mara</strong><strong>and</strong> Serengeti. The famous wildlife migration in the Serengeti/<strong>Mara</strong> plains is driven bythe search for pasture <strong>and</strong> water. The spectacular scene <strong>of</strong> large numbers <strong>of</strong> wildlifecrossing the <strong>Mara</strong> River has been classified as one <strong>of</strong> the wonders <strong>of</strong> the world.Significant changes in water supplies from the <strong>Mara</strong> River <strong>and</strong> the <strong>Mara</strong> River Basinecosystems would seriously affect the wildlife sectors <strong>of</strong> <strong>Trans</strong> <strong>Mara</strong> <strong>and</strong> Serengetiwhich generate large amounts <strong>of</strong> foreign exchange, support many enterprises <strong>and</strong>create employment opportunities.6.1.5 Wetl<strong>and</strong>sThe l<strong>and</strong> use changes in the upper <strong>Mara</strong> River catchments (mostly increased settlements<strong>and</strong> agricultural activities) have increased flooding frequency <strong>and</strong> peaks withsubsequent build up <strong>of</strong> sediments in the lower end <strong>of</strong> the flood plains. The increasedsedimentation on the flood plains increased the area under wetl<strong>and</strong>s by 38% between1986 <strong>and</strong> 2003 to 1,394.4 km 2 <strong>and</strong> displaced many people, adversely affecting theirlivelihood based agricultural activities (Khroda, 2010 )6.2 The Impacts <strong>of</strong> Current Status on the <strong>Total</strong> <strong>Economic</strong> <strong>Value</strong>sResults in Table 11 show that in general the current activities in the three forest blockswill reduce the ecosystem stocks <strong>and</strong> flows hence their total economic values if nourgent intervention to reverse the trend is undertaken. The impacts <strong>of</strong> the current statuson the total economic values <strong>of</strong> the forest blocks are similar <strong>and</strong> therefore arecrosscutting. Except for the status <strong>of</strong> wetl<strong>and</strong>s, most factors will negatively affect thestock <strong>and</strong> flows <strong>of</strong> goods <strong>and</strong> hence the elements <strong>of</strong> the aggregated goods <strong>and</strong> servicesoutlined in TEV.59
