Answer:
The list of the various methods and techniques which are used in sustainable agriculture are given below:
1. Contour Ploughing
This technique or method of farming prevents soil erosion such as reduced crop productivity, worsened water quality, lower an effective reservoir water levels, flooding and habitat destruction. It is different from terrace farming because in terracing wide steps are cut around the slopes. In this technique or method, the ruts are perpendicular rather than slopes made by the plough, generally resulting in furrows that curve around the land and are level.
2. Drip Irrigation
It is also known as trickle irrigation or micro irrigation. In this method, water is irrigated to the roots of the plants by dripping, either onto the soil surface or directly onto the root zone, through a network of valves, pipes, tubing and emitters.
3. Agroforestry
It is an integrated approach of using the interactive benefits from combining trees and shrubs with crops. It combines agricultural and forestry technologies to create more diverse, productive, profitable, healthy and sustainable land-use systems. It has a lot in common with intercropping. Both have two or more plant species (such as nitrogen-fixing plants) in close interaction. The Food and Agriculture Organisation of United nations (FAO) recognises seven major challenges and obstacles of agroforestary:
(1) Delayed return on investmen
(2) Under-developed markets
(3) Emphasis on commercial agriculture
(4) Limited awareness of the advantages of agroforestry
(5) Unclear status of land and tree resources
(6) Adverse regulations
(7) Lack of coordination between sectors
