Course overview and lesson index for ELEC 13, focused on natural-resource classification, conservation, governance, and sustainable development.
Management of natural resources in agriculture means planning the use, protection, and regeneration of land, water, forests, and biodiversity so farming stays productive without degrading the ecological base that supports it.
Natural resources are materials and ecological assets we get from nature, such as soil, water, forests, minerals, air, plants, and biodiversity, which support farming, livelihoods, and development.
Renewable resources can recover naturally over time when managed properly, such as forests, water, and soil fertility, while non-renewable resources like many minerals and fossil fuels are finite and are not replenished within a human timescale.
Soil conservation is important because erosion, salinity, nutrient loss, and land degradation reduce crop productivity, water-holding capacity, and long-term farm sustainability, so measures like contouring, cover, bunding, and better land use are central to resource management.
Watershed management means treating land and water together within a drainage area so runoff, erosion, moisture conservation, groundwater recharge, and livelihoods are improved through an integrated approach rather than isolated field-level action.
Biodiversity supports agriculture through pollination, pest regulation, soil health, resilience, and genetic resources for crop improvement, so conserving species, habitats, and agro-biodiversity helps farming remain stable under stress.
Common property resources are shared resources like grazing lands, village ponds, community forests, and wastelands that are used collectively, which makes local rules, access rights, and community management important for avoiding overuse and degradation.
EIA, or Environmental Impact Assessment, is a systematic process used to identify likely environmental and social impacts of a project before implementation so decision-makers can compare alternatives, plan mitigation, and reduce long-term damage.
