Question

how can farmer use water economically??​

Answer 1

Answer:

Hi mate

Explanation:

Water used for irrigation can be pumped from reserves of groundwater, or abstracted from rivers or bodies of stored surface water. It is applied to crops by flooding, via channels, as a spray or drips from nozzles. Crops also obtain water from precipitation.

Answer 2

Explanation:

Agriculture has, arguably, been very successful at capturing the major share of the world’s exploitable water resources. However, the environmental and socio-economic rationale for this capture by the sector is now being questioned. This review presents a framework and a suite of techniques for analysing these issues and making the rationale explicit and transparent. It is not a field manual but rather an 'advocacy' brief. It sets out to bring together economic and ecological evidence and argumentation in support of the need to challenge and change the fundamentals of the prevailing technocentric view of water resources exploitation. A new and more suitable approach to water resources allocation is necessary if the world’s population is to be adequately fed, without further degradation and destruction of the planet’s critical ecosystem services. Water productivity needs to be enhanced considerably, and economic cost-benefit analysis and pricing regimes can play a significant role in such a process. However, these economic measures will not be sufficient on their own. They will need to be buttressed by technological innovation and institutional changes in order to encourage a more equitable distribution of resources and to mitigate potential international conflicts across 'shared' water basins.
