Using hybrid varieties of seeds will improve crops' ability to withstand drought, resist pest attacks, and will provide higher yield. Some economists argue that the Indian farmers should diversify and produce high value crops to export to international markets. Land degradation can be mitigated by using environmentally-friendly agricultural tools and technologies.
Fragmented land is not suitable for large scale farming. These parcels of land are of irregular shapes, limiting the use of modern machines. Furthermore, fragmented land also limits the development of drainage and irrigation systems.
