4.1 Sustainability of developments of gully susceptible riparian areas
Gully eroded land with severe situation falling all along river systems in India were brought up about three decades ago, which produced enhanced yields and contributed country’s production. Usually the expected useful life of land developments is taken up for 10 years. Thus, by now the development of land has already passed successful life. Therefore, it needs revamping of riparian areas for restoration of productivity. The main widely spread drawback is lack of plant nutrient in the form of macro and micro nutrients.
Post developments inducement of prosperity that brought urbanization and development of urban facility in rural areas, which followed disposal of untreated waste waters in gullies that ultimately joined major river systems causing pollution of river water. Further, climate change adversely suppressed ground water level, making the riparian areas water wells getting dried. Thus, the productivity of systems have again been declining.
