Due to limited access to water, it is necessary to determine the comparative advantage of crops and horticultural products in different parts of the province and identify products that lack the desired productivity. Then, find ways to improve water productivity or replace products with higher comparative advantage with low-yield products. Based on this, the crop and economic productivity index ...
متن کاملWater Soluble Vitamins for Dairy Cattle
Research on effects of water soluble vitamins when fed to dairy cows and field supplementation of some water soluble vitamins has increased markedly in the past few years. In research studies, biotin supplementation (20 mg/ day) has consistently improved hoof health of cows and often increased milk production. Supplementation of niacin, although common, has little effect on milk production unle...
متن کاملComplementarities of water-focused life cycle assessment and water footprint assessment.
T recent past has shown two parallel developments: the water resources community discovered the relevance of supply chain thinking for water resources management and freshwater allocation, while the life cycle assessment (LCA) community recognized the importance of water use and included those related impacts in LCA studies. The water footprint concept was introduced by Arjen Hoekstra as an ind...
