2. Practising crop rotation improves soil structure, fertility, and reduces the build-up of pests and diseases, reducing the need for chemical inputs. This is environment-friendly.
3. Carrying out a large scale irrigation system in semi-arid areas can lead to unsustainable water use, depletion of water sources, and soil salinization, making it generally not environment-friendly.
4. Using organic fertilizers improves soil health, water retention, and fertility without introducing synthetic chemicals, which is environment-friendly.
