Presently, ______ population resides within watershed areas, converting forested land into agricultural plots for food cultivation:
Show answer Hide answer
Answer: A. 50-80%
Explanation
Socioeconomic studies indicate that fifty to eighty percent of watershed residents practice farming. Rising local populations increase food demand, prompting the clearing of steep forested hillsides. Agricultural conversion in mountainous watersheds accelerates soil erosion and sedimentation downstream. Watershed areas capture precipitation and channel runoff into vital river systems and reservoirs. Subsistence farming remains the primary economic activity for rural communities living in remote hills. Deforestation for crop cultivation disrupts hydrological cycles and reduces soil stability.
Watershed management programs work to introduce sustainable agricultural practices among local populations. Preventing soil erosion requires balancing food security needs with forest conservation regulations. Downstream hydroelectric dams suffer from siltation caused by extensive agricultural land conversion upstream. Option b overestimates the lower bound of population percentage reported in watershed studies. Option c suggests higher demographic conversion rates than standard socio-economic forestry surveys indicate. Option d exceeds typical estimates for agricultural land conversion within fragile watershed areas.
