Land degradation refers to any reduction or loss in the biological or economic productive capacity of the land resource base. It is generally caused by human activities, exacerbated by natural processes, and often magnified by and closely intertwined with climate change and biodiversity loss. SLM practices include the integrated management of crops (trees), livestock, soil, water, nutrients, biodiversity, disease and pests to optimize the delivery of a range of ecosystem services. The overall objective is to maximize provisioning services (e.g. food, water, energy) while enhancing the resilience of land resources and the communities that depend on them.
