The study reveals that soil erosion in the Jonk River Basin is a significant threat to agriculture and the environment. The most affected areas, such as sub-basin SB-8, experience annual soil losses of up to 137.5 tonnes per hectare, which could lead to reduced agricultural productivity and long-term environmental degradation. The region's vulnerability is exacerbated by its reliance on monsoon rains, which are concentrated in a short period, causing intense runoff and soil loss. The lack of adequate soil conservation measures, such as vegetative stabilisation and water management structures, further increases the risk of erosion, threatening the livelihoods of local farmers and the sustainability of the ecosystem.
