Restoring wetlands aids in natural water filtration, reducing pollutants, and increasing water storage capacity. AFFORESTATION & REFORESTATION Reforestation is the process of planting trees in a forest where the number of trees has been decreasing. Afforestation is when new trees are planted or seeds are sown in an area where there were no trees before, creating a new forest. Tree planting improves water quality and increases groundwater recharge by reducing soil erosion and filtering contaminants before they reach bodies of water. AGRICULTURE PRACTICES All the activities that farmers undertake during cultivation of crops is referred as agricultural practices. Techniques like crop rotation, organic farming, and reduced pesticide use help prevent water pollution and maintain soil health, which in turn supports water quality. POLLUTION CONTROL Pollution control is the limitation or eradication of the release of harmful substances into the environment. The removal of dangerous substances can be considered pollutant control as well. Water contamination can be avoided by implementing and enforcing regulations to limit urban runoff, regulate fertilisers, and reduce the discharge of industrial waste. WATER MANAGEMENT Water management is the control and movement of water resources to minimize damage to life and property and to maximize efficient beneficial use. Conservation practices like rainwater harvesting and wastewater treatment increase water availability and improve water quality for communities. NEGATIVE ACTIVITIES Wastewater Management Deforestation Urban Development Mining Industrial Activities WASTEWATER MANAGEMENT Wastewater management is an important approach to protect water resources and it is defined as the collection, treatment, and reuse of wastewater Inadequate treatment of wastewater can introduce harmful pollutants into water bodies, threatening the quality of water for humans and wildlife. DEFORESTATION Deforestation is the purposeful clearing of forested land. Throughout history and into modern times, forests have been razed to make space for agriculture and animal grazing, and to obtain wood for fuel, manufacturing, and construction. Removing trees reduces the natural filtration of water and can lead to increased runoff and erosion, degrading water quality. URBAN DEVELOPMENT Urban development is the development of cities and other urban areas. More impervious surfaces increase stormwater runoff, which carries pollutants into water bodies, contaminating supplies and reducing groundwater recharge. MINING Mining is the industry and activities connected with getting valuable or useful minerals from the ground, Mining operations can lead to sedimentation and the release of harmful substances, negatively impacting water quality and availability. INDUSTIAL ACTIVITIES Industrial activity means the manufacturing, production, assembling, processing, recycling, adapting or servicing of, or the research and development of any goods, substances, food, products or articles for commercial purposes, Factories often release toxic chemicals and heavy metals into water sources, jeopardizing safety and affecting ecosystems. THANK YOU!
