This variability stresses the diverse dietary adaptations among slug species and their ecological roles in fungal consumption. [29] Moreover, by consuming fungi, snails and slugs can also indirectly help in their dispersal by carrying along some of their spores [29] [34] or the fungi themselves. [35]
The major river in Ethiopia is the Blue Nile. However, most drinking water in Ethiopia comes from ground water, not rivers. Ethiopia has 12 river basins with an annual runoff volume of 122 billion m 3 of water and an estimated 2.6–6.5 billion m 3 of ground water potential.

Sand and water on the side of the road, causing erosion on the environment Plastic bags dumped by the road side in Katete in mbarara district in western Uganda. The erosion caused by rains, rivers and winds as well as over-use of soils for agriculture and low use of manures have resulted in turning the soils infertile, as for example, in the plains of the Nile and the Orange River.
Water pollution (or aquatic pollution) is the contamination of water bodies, with a negative impact on their uses. [31]: 6 It is usually a result of human activities. Water bodies include lakes, rivers, oceans, aquifers, reservoirs and groundwater. Water pollution results when contaminants mix with these water bodies. Contaminants can come from ...
Agriculture dominates water use (about 89% of total water use in the basin) and is expected to continue to be the basis for economic growth in the coming years. Crop production in particular is a major component of the basin's economy and has seen rapid growth in recent years, with the value of output expanding by 7.9% per year in real terms ...
The definition of ecosan has varied in the past. In 2012, a widely accepted definition of ecosan was formulated by Swedish experts: "Ecological sanitation systems are systems which allow for the safe recycling of nutrients to crop production in such a way that the use of non-renewable resources is minimized.
