Under the premise that the water scarcity issue is inherently multidimensional, a composite Water Poverty Index has been developed, to complement the traditional physical water indicators. In this paper we propose some technical refinements based on principal component analysis, in order to improve the...
By 2030, substantially increase water-use efficiency across all sectors and ensure sustainable withdrawals and supply of freshwater to address water scarcity and substantially reduce the number of people suffering from water scarcity 6.4.1:Change in water-use efficiency over time 6.4.2:Level of water...
challenge, not only to the general population in Africa, but specifically to the population group of pregnant women. To our knowledge, a comprehensive review of PA during pregnancy in Africa does not exist. This knowledge gap is worrisome because the correlates, perceived benefits and barriers to ...
Africa imported 0.38 Tg physical P through agricultural trade in 2016, which significantly alleviated P deficits in Africa40. The import of virtual nutrients meant the conservation of domestic nutrient resources, especially P (due to the low cost-effectiveness of recycling through natural cycling, ...
1c)21,22. Some surplus phosphorus can be stored in soils as legacy P and can be used for future crop uptake. However, a fraction of surplus nutrients are lost to the environment and likely affects air and water quality. Lassaletta et al.20 and Lun et al.23 estimated the N and P ...
"Tightness abounds" in the scrap market, he said. "It's D-R-Y dry out there." Cathode demand has improved, agreed a cathode merchant, but he conceded that wire rod demand was weak. He put premiums for electrowon cathode at 2.5 cents/lb over spot COMEX (net cash, US Midwest ...
In West Africa, the construction of small earth dams is common against water scarcity. Burkina Faso, an inland country in West Africa, is home to 1001 dams that serve agricultural and pastoral needs. These embankments are predominantly made of compacted laterite, a cost-effective material abundant...
Important lakes in Africa are Lake Victoria, Lake Tanganyika, and Lake Nyasa. Climate of Africa is warm, with hot summers and mild winters. The amount of rainfall varies greatly. Deserts receive too little water for farming, while some other areas get excessive rainwater. Although Africa ...
ataxacantha as pseudoZamnès during food scarcity times. The pseudoZamnès are not supposed to be sold in the markets but could be a source of fraud. Compared to Zamnè, they are not much appreciated due to the hard-to-cook problem and the lower palatability. Easy processability and high ...
