Introduction An ecosystem is a community of living organisms (plants‚ animals and microbes) in conjunction with the nonliving components of their environment (things like air‚ water and mineral soil)‚ interacting as a system.[2] These biotic and abiotic components are regarded as linked together through nutrient cycles and energy flows.[3] As ecosystems are defined by the network of interactions among organisms‚ and between organisms and their environment‚[4] they can be of any size but usually

Water pollution is the contamination of water bodies (e.g. lakes‚ rivers‚ oceans‚ aquifers and groundwater). Water pollution occurs when pollutantsare directly or indirectly discharged into water bodies without adequate treatment to remove harmful compounds. Water pollution affects plants and organisms living in these bodies of water. In almost all cases the effect is damaging not only to individual speciesand populations‚ but also to the natural biological communities. Introduction[edit]

The Azande people live between the longest river in the world‚ the Nile river‚ and the Congo river on a continental divide that separates the two drainage basins. This is located in Africa on the borders of Central African Republic and South Sudan. The area of land is fairly big at approximately 1‚200 miles long with many streams and different rivers running through‚ tall trees on the river banks‚ and much grass land. This divide was made 1885 when the Europeans created a boundary British influences

ensuring minimum water loss and to get optimum yield. Various methods of irrigation are: 1. Surface method 2. Sub-surface method 3. Sprinkler method 4. Drip method Surface method In the surface system‚ water flows by gravity either through furrows basins or borders. In this type‚ water loss by conveyance and deep percolation is heavy and the efficiency of irrigation is only 40 to 50% at field level. Efficiency can be improved by lining the canal and by proper leveling of the field. Sub-surface method

1. Introduction 1.1 Background The International Geotechnical Societies’ UNESCO working Party on World landslide inventory defined landslides as “the movement of a mass of rock‚ debris or earth down a slope”. (Sassa et.al.‚ 2007). Landslides as described by the Dahal (2006) are a downward movement of rock materials or debris or soil along the slope‚ when shear stress exceeds shear strength of the material. Many classification of landslides have been found in literature among them are the classification
