Effects of deforestation, per the chapter: burning forest wood releases stored carbon (the opposite of carbon sequestration); loss of soil-binding roots increases erosion and, in dry areas, can cause desertification; increased surface run-off causes flash flooding and reduces moisture/humidity; altered local precipitation patterns trigger drought in many regions; biodiversity declines sharply as habitats are disturbed; forest-dependent people lose their livelihood; global warming increases, with deforestation accounting for about one-third of total CO2 emissions; and life-support resources such as fuel, medicinal herbs and wild edible fruits are lost.
Step 2. Benefits of agroforestry, per the chapter, directly counter several of these: it helps conserve soil and water (stabilising salinity/water table, reducing landslide and run-off), improves nutrient cycling and organic matter, and the tree component maintains a microclimate that balances O2-CO2 levels, temperature and humidity for the intercropped land.
Step 3. Agroforestry is additionally suited to dry land with minimal rainfall, offering an alternate land-use pattern where pure cropping might fail, and its multipurpose tree species (e.g., Acacia for wood pulp, tanning, paper and firewood) provide economic returns alongside the ecological benefits, while intercropping raises yield and lowers operating costs versus monoculture forestry or farming alone. …
