The process of desertification does not have climatic boundaries. Justify with examples
It's true that desertification is not strictly a phenomenon of arid climates; it is a process of land degradation that can occur anywhere. It signifies the loss of the land's biological productivity, which can happen even in sub-humid and humid regions, thus crossing climatic boundaries.
The primary driver is often human activity, not just a lack of rain. For example, large-scale deforestation in the Amazon basin, a humid tropical region, leads to soil erosion and nutrient loss, creating barren, desert-like patches of land. The soil, stripped of its protective cover, gets baked by the sun and loses its ability to support life.
Similarly, in parts of Punjab, a semi-arid to sub-humid region, faulty irrigation practices have led to waterlogging and soil salinization. This turns once-fertile agricultural land unproductive and sterile, mirroring the conditions of a desert. These examples show desertification is a human-induced degradation process, not one dictated by climate alone.
