Agroforestry: Climate-Smart Agriculture for Increased Resilience and Food Security in a Changing Climate
摘要
The atmospheric concentration of greenhouse gases due to anthropogenic activity has steadily increased throughout time, contributing to global warming. The most recent nine years have been among the warmest on record. This temperature increase is anticipated to affect agriculture in a number of ways, including increasing crop evapotranspiration, altering the salinity of the soil, reducing crop production and nutrient use efficiency, and changing insect-pest distribution. Climate change will put additional strain on already scarce water resources in some areas, especially in dry regions. Agroforestry has emerged as a field that addresses biodiversity conservation, carbon sequestration, climate change adaptation and mitigation, landscape restoration, as well as livelihood stability for communities. Agroforestry improves ecological processes and regulates ecosystem services such as erosion control, nutrient retention, water and air quality, pollination, and insect control. The contribution of agroforestry practices to improving food security, agroforestry-based solutions for coping with climate change, and the optimum use of natural resources through agroforestry interventions are discussed in view of the developing issues of climatic variability. Techniques for agroforestry have also been suggested as a strategy to boost agricultural production in degraded ecosystems. The restoration of sodic and saline waterlogged areas, severely degraded ravine lands, mine spoil areas, stabilizing sand dunes, and utilization of low-quality waters using agroforestry technologies are highlighted.
