What is water resource management?
Explanation: The correct answer is C) The planning and implementation of strategies to ensure sustainable water use. Water resource management involves the planning, development, and implementation of strategies, policies, and practices to ensure the sustainable use and allocation of water resources. It includes activities such as water conservation, water quality management, water supply planning, and the protection of water ecosystems.
What is water scarcity?
Explanation: The correct answer is C) The lack of access to clean and safe water. Water scarcity refers to the limited availability of freshwater resources relative to the demand for water. It occurs when there is insufficient access to clean and safe water for drinking, sanitation, agriculture, and other essential needs. Water scarcity can be caused by factors such as population growth, climate change, pollution, and inefficient water management.
What is water conservation?
Explanation: The correct answer is C) The reduction of water waste and the efficient use of water. Water conservation refers to the practice of reducing water waste and using water resources efficiently. It involves adopting measures and technologies to minimize water consumption, such as using water-saving fixtures, implementing efficient irrigation methods, and promoting awareness about responsible water use. Water conservation helps preserve water resources, mitigate water scarcity, and protect the environment.
What is groundwater depletion?
Explanation: The correct answer is B) The extraction of water from underground aquifers exceeding recharge rates. Groundwater depletion refers to the long-term decline in groundwater levels due to excessive pumping or extraction of water from underground aquifers. When the rate of water extraction exceeds the rate of recharge, it can lead to the depletion of groundwater resources. Groundwater depletion can result in land subsidence, saltwater intrusion, and the drying up of wells, affecting both human and ecological systems that depend on groundwater.
What is water pollution?
Explanation: The correct answer is C) The introduction of harmful substances into water bodies. Water pollution refers to the contamination or degradation of water bodies, such as rivers, lakes, oceans, and groundwater, by the introduction of harmful substances. These substances can include pollutants such as chemicals, heavy metals, pathogens, and nutrients from human activities such as industrial discharges, agricultural runoff, and improper waste disposal. Water pollution can have detrimental effects on aquatic ecosystems, wildlife, and human health.
