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.
