Soil erosion is a major problem everywhere, but it poses an especially serious danger to agricultural productivity in the tropics. Reduced crop yields and lower farm profitability are possible if the rate of soil erosion exceeds the rate at which topsoil is replenished. In order to ensure the long-term viability of an agricultural system, it is crucial to strike a balance between soil-building and soil-depleting practices. Soil erosion is a major cause of land deterioration in the semiarid Lower Chambal Valley. In this analysis, we compare Landsat satellite pictures from 1977, 1990, and 2000 to see how the degraded land in this region has changed over time. The data we have shows that degraded land is expanding at a pace comparable to the invasion of arable land. The proportion of degraded land to total planted area is inversely related to harvest success, according to field survey data. The gross value of agricultural production in a region is directly correlated with the degree to which land has been degraded. By factoring in the high levels of degraded land, a simple linear regression model may explain the substantial difference in productivity. This research provides evidence that shows how land degradation may lead to a decrease in a region's food supply.
