AGRICULTURAL POLLUTION AND ENVIRONMENTAL MANAGEMENT: SOURCES, IMPACTS, MITIGATION STRATEGIES, AND FUTURE CHALLENGES

Abstract

Agriculture is fundamental to global food security, rural livelihoods, and economic development; however, the intensification of agricultural production has contributed to environmental pollution and the degradation of natural resources. Agricultural pollution arises from the excessive application of chemical fertilizers and pesticides, livestock waste, improper manure management, crop residue burning, irrigation-induced salinity, soil erosion, and the release of contaminants into surface water and groundwater. These activities can adversely affect soil fertility, water quality, atmospheric composition, biodiversity, and human health. Agricultural pollution also contributes to greenhouse gas emissions through fertilizer-derived nitrous oxide, methane released from livestock and rice cultivation, and carbon dioxide emissions associated with land-use change and agricultural energy consumption. Environmental management in agriculture therefore requires an integrated approach that combines sustainable farming practices, efficient nutrient management, biological pest control, conservation agriculture, improved waste treatment, precision technologies, and effective environmental governance. This review examines the major sources of agricultural pollution, their environmental and socioeconomic consequences, and the mitigation strategies available for reducing pollution while maintaining agricultural productivity. It also discusses emerging technologies, policy interventions, and future challenges associated with climate change, population growth, resource scarcity, and the transition toward sustainable food systems. The review emphasizes that coordinated action among farmers, researchers, policymakers, agricultural industries, and local communities is essential to minimize pollution and achieve long-term environmental sustainability.
