Explain how farming and deforestation activities in highland areas contribute to flooding and mudslides in the lowlands, and what benefits conservation efforts would bring.

a) The farmers' activities directly contribute to the challenges during heavy rains.

• Digging up and down the hill to grow crops disturbs the soil, making it loose and highly susceptible to erosion.
• Cutting down trees for charcoal removes the vital root systems that hold soil together, leading to increased soil erosion and mudslides. The absence of trees also reduces water absorption, increasing surface runoff and contributing to flooding in the valleys.
• Grazing large herds of cattle removes vegetation cover, exposing the soil to direct impact from rain and further loosening it, which exacerbates erosion and mudslides.
• Brick laying often involves excavating soil, further destabilizing the land and increasing its vulnerability to heavy rainfall.

b) Conserving such areas offers several significant benefits:

• It helps prevent soil erosion and reduces the occurrence of mudslides by maintaining vegetation cover and stable soil structures.
• Conservation regulates water flow, allowing more water to infiltrate the ground and reducing rapid surface runoff, thereby minimizing flooding in the valleys.
• It preserves biodiversity by protecting natural habitats and ecosystems.
• Conserving these areas ensures long-term ecological stability and sustainable resource availability for the community.
