Question

2. Which of the following methods of irrigation is adopted extensively in areas of
acute water shortage?
a) Chain pump system b) Drip irrigation c) Sprinkler system d) Furrow irrigation

Answer 1

Answer:

Explanation:

Irrigation can increase agricultural yield by up to 50 percent. Using renewable energy in pumping and irrigation can therefore not only reduce greenhouse gas emissions, but also lower the costs of buying diesel or kerosene fuels and increase the sources of income for large and small-scale farmers. In addition, regions that are off-grid or without reliable access to electricity due to constant blackouts can benefit from renewable energies. If efficient irrigation methods like drip irrigation are implemented, valuable water resources can be saved and the use of arable land for irrigated crops increases, leading to an extra source of income. The additional vegetated land cover will furthermore allow the protection of the increasingly threatened soil resources. A win-win for our farmers and the environment.

However, although irrigation acts as the backbone of local economic development in the Global South, many barriers hinder farmers from efficient irrigation uses in these regions: the main obstacles include the missing access to reliable energy sources, the lack of information about appropriate technologies as well as barriers to financing options. Using clean energy for irrigation such as solar power can increase production and create access to electricity while saving financial resources.
