Water security encompasses a range of measures aimed at ensuring access to safe water, protecting water resources, and promoting sustainable water use.

UN-Water is a UN inter-agency mechanism that coordinates the efforts of various UN agencies and partners on water-related issues, including water security.

Water poverty refers to the lack of access to safe water and sanitation services, which can have severe consequences for health, education, and economic development.

Climate change, population growth, and pollution are all major factors that can lead to water insecurity by affecting the availability, quality, and accessibility of water resources.

Integrated water resources management is a holistic approach to water management that considers the interconnections between water, land, and other resources, and aims to balance social, economic, and environmental needs.

Investing in water infrastructure, promoting water conservation practices, and protecting watersheds are all examples of measures that can be taken to enhance water security.

Water scarcity refers to the situation where there is not enough water to meet the needs of a population, often due to factors such as climate change, population growth, and pollution.

Lack of political will, insufficient financial resources, and limited technical capacity are all major challenges that can hinder efforts to achieve water security.

Water pollution, water contamination, and water degradation all refer to the situation where water resources are contaminated with harmful substances, which can pose a risk to human health and the environment.

Droughts, floods, and water pollution are all examples of water security risks that can have significant social, economic, and environmental consequences.

Water allocation refers to the process of determining how water resources should be shared among different users, such as households, industries, and agriculture.

Equity, efficiency, and sustainability are all key principles of integrated water resources management, which aims to balance social, economic, and environmental needs.

Sustainable water management refers to the management of water resources in a way that ensures their availability and quality for future generations.

Rainwater harvesting, greywater reuse, and water-efficient irrigation are all examples of sustainable water management practices that can help to conserve water resources.

Community-based water management, participatory water management, and decentralized water management all refer to approaches to water management that involve local communities in decision-making and implementation processes.
