Answers
Answer:
Ever-increasing demands on the land from economic development, burgeoning cities and growing rural populations are driving unprecedented land use change. In turn, land use change is driving land degradation: soil erosion, nutrient depletion, salinity, water scarcity, pollution, disruption of biological cycles, and loss of biodiversity. This affects peoples' livelihoods, by threatening their food and water supply, lowering the quality of their living environment, decreasing biodiversity, etc. To address these challenges, Sustainable Land Management offers a range of interventions to prevent or reduce land degradation.
