The first environmental effect is increased crop growth, such as in the Rubaksa gardens in Ethiopia The irrigation that grows crops, especially in dry countries, can also be responsible for taxing aquifers beyond their capacities. Groundwater depletion is embedded in the international food trade, with countries exporting crops grown from ...
All plants, including crop, require air (specifically, oxygen) to respire, produce energy, and keep their cells alive. In agriculture, waterlogging typically blocks air from getting to the roots. [3] With the exception of rice (Oryza sativa), [4] [5] most crops like maize and potato, [6] [7] [8] are therefore highly intolerant to waterlogging.
To adequately address the issue of water scarcity in Africa, the United Nations Economic Commission for Africa emphasizes the need to invest in the development of Africa's potential water resources. This would improve food security and water security, and protect economic gains by effectively managing droughts, floods, and desertification. [4]
The main sources of Africa's 3.6% share of the world's Carbon dioxide emissions are gas flaring in the Niger Delta and coal-fired power plants in South Africa. [23] But, the continent's forests are rapidly disappearing because of desertification and deforestation, which has negative consequences for both Africa and the climate at large. [24]
Large portions of the continent may become uninhabitable as a result of the rapid effects of climate change, which would have disastrous effects on human health, food security, and poverty. [41] [42] [43] Regional effects on rainfall in the tropics are expected to be much more spatially variable. The direction of change at any one location is ...
Waterlogging or water logging may refer to: Waterlogging (agriculture), saturation of the soil by groundwater sufficient to prevent or hinder agriculture; Waterlogging (archeology), the exclusion of air from an archeological site by groundwater, preserving artifacts; Underwater logging, the process of harvesting trees that are submerged under water
The environmental impact of agriculture is the effect that different farming practices have on the ecosystems around them, and how those effects can be traced back to those practices. [1] The environmental impact of agriculture varies widely based on practices employed by farmers and by the scale of practice.
This use is non-consumptive and is thus available for other uses further downstream. Hydropower plants exist at the Aswan High Dam (2100 MW), the old Aswan Dam (270 MW)and power plants at the Esna (90 MW) and Naga Hammadi weirs (64 MW). Together these plants accounted for 16% of installed electricity generation capacity in 2004. [30]
