In the developing world, a common feature in small and medium-sized river basins that drain into arid lands is the lack of meteorological and hydrological records [. SPOT-VEGETATION Programme. The Ewaso Ng’iro River Basin, Kenya, is a prime example of the consequences that unplanned river basin development has on livelihoods of downstream users. Further analysis of 12 years of monthly SPOT-VEGETATION satellite imagery reveals higher NDVI (Normalized Differential Vegetation Index) values in the swamp than nearby rainfed areas, with the difference in NDVI between the two positively related to river water discharged into the swamp. The Lorian Swamp in the lowlands of Isiolo District in Kenya receives water from the Ewaso Ng’iro River, which drains the slopes of the Aberdares Mountains and Mount Kenya [2,8]. Available online: Mati, B.M. Ewaso Nyiro basin covers an area of about 210,226 km2, 36.3%, of Kenya drainage area and bears 5.8% of Kenya water potential with an annual yield of 1469 million m3.

The Lorian Swamp in the lowlands of Isiolo District [, The Merti Aquifer, situated in the lower part of the Ewaso Ng’iro catchment (, The vegetation of the swamp has three different zones; the upper, We calculated the number of days per year when river water entered the head of the swamp, as well as the number of months when river water reached the end of the swamp as follows. Such effect did indeed existed; the difference in NDVI between the swamp and its surrounding rainfed area increased significantly with the amount of water that entered the swamp over the preceding two months (, Three outliers in the upper left part of the graph (, This was indeed the case; in both years, there was an area to the southwest of the swamp that was green (, The three categories of water, the final services delivered by these water categories and the benefits they provide to people are described in. International Livestock Research Institute (ILRI), P.O. Our Environment our Life. Although the main river originates from the Nyandarua range, the tributaries originating from Mt.

The Lorian Swamp is an area of wetlands on the Ewaso Ngiro river in Wajir South, North Eastern Province, Kenya. Impacts of environmental change on water resources in the Mount Kenya region. River Ewaso Nyiro drains the slopes of the Aberdare Range and Mount Kenya crossing over the flush and arid Laikipia Plateau and Archer’s Post beyond which it crosses an undulating plateau where it changes to an ephemeral river to discharge its waters near Habaswein, into Lorian Swamp.

Local annual rainfall averages between 180 and 250 mm, but varies widely from year to year. It rises near Valencia on the southern edge of the Northern Range uplands and flows roughly west to empty via the saline mangrove channels of the Caroni Swamp into the Gulf of Paria , between Trinidad and Venezuela, a mile or so south of Port of Spain . The major rivers from Aberdare Forest are Athi and Tana, which flow into the India Ocean, Ewaso Nyiro that drains into the Lorian Swamp and River Malewa that drains into Lake Naivasha. We next used monthly SPOT VEGETATION NDVI data to visualize the vegetation phenology of the swamp and the surrounding areas for every month over a twelve-year period and related the contrast in NDVI between the frequently inundated part of the swamp and adjacent upland rainfed areas to the discharge of water into the swamp. Notter, B.; MacMillan, L.; Viviroli, D.; Weingartner, R.; Liniger, H.P.

The river passes through the Laikipia plateau and Archer’s Post beyond which it crosses an undulating plateau where it changes in an ephemeral river to discharge its waters near Merti into the … If drainage of this swamp will, as of necessity, have to go on, the ministry would prefer that EIA be carried out to determine and mitigate the impacts the activity will have on the hydrology and ecology of lakes Victoria, Kanyaboli and Sare river. During this period, and particularly in drought years, livestock is attracted to the swamp by the availability of surface water and forage resources. Our results suggest that the benefits from surface water are sensitive to abstractions upstream, as increases in abstractions result in higher frequency of the river running dry.
