The Sustainable Development Goals (SDGs) are the blueprint for the United Nations to build a more sustainable future for all. Its adoption has made environmental degradation, sustainability, climate change and water security the focus of international attention.

Sustainable Development Goal 6 (SDG 6 or Global Goal 6) is about "all people have access to safe water and sanitation". It is one of the 17 Sustainable Development Goals established by the United Nations General Assembly in 2015. The official wording is: "Ensure that all people have access to water and sanitation facilities and manage them sustainably." The goal has eight goals: at least in 2030 achieve. 11 indicators will be used to measure progress towards the goal

Sustainable management of water resources and access to safe water and sanitation are essential for unlocking economic growth and productivity and provide significant leverage for existing investments in health and education. The natural environment e.g., forests, soils and wetlands contribute to management and regulation of water availability and water quality, strengthening the resilience of watersheds and complementing investments in physical infrastructure and institutional and regulatory arrangements for water access, use and disaster preparedness. Water shortages undercut food security and the incomes of rural farmers while improving water management makes national economies, the agriculture and food sectors more resilient to rainfall variability and able to fulfil the needs of growing population. Protecting and restoring water related ecosystems and their biodiversity can ensure water purification and water quality standards.

Clean water and sanitation Water scarcity affects more than 40% of people, and this number is expected to increase as temperatures rise. Although 2.1 billion people have improved their water sanitation since 1990, the decline in drinking water supplies is affecting every continent. More and more countries are facing the pressure of water shortage and increasing drought and desertification have exacerbated these trends. By 2050, at least a quarter of people are expected to experience repeated water shortages. By 2030, providing safe and affordable drinking water for all requires us to invest in adequate infrastructure, provide sanitation facilities, and promote personal hygiene. Protecting and restoring water-related ecosystems is essential. Ensuring universally safe and affordable drinking water involves more than 800 million people who lack basic services and improving access to services and safety for more than 2 billion people. In 2015, 4.5 billion people lacked safe and managed sanitation services (excreta was disposed of or disposed of properly) and 2.3 billion lacked even basic sanitation facilities.

The book, "Climate change and water security: impact, the future" "Prediction, adaptation and mitigation" provides an overview The impact of climate change on all water-related sectors, including Water quantity, water quality, water-related diseases, water Rely on biodiversity, freshwater, and water-dependent oceans Ecosystems, water-dependent food production (agriculture, Fisheries), greenhouse gas (GHG) emissions in the water sector and Mitigation and adaptation measures to water climate change Safety. More dominant Climatic factors that affect the amount of water or available water are rainfall, runoff and river flow, floods, drought, snow, Glaciers, sea level rise (SLR), etc. Observed impact of climate change on the world's water  resources. The amount includes the trend of increasing rainfall in high latitudes and temperate regions and decreasing rainfall in low latitudes. Compared to all other natural disasters, floods are the most reported natural disaster event in Africa, Asia, and Europe. In the case of Bangladesh, there were six extreme floods in 1974, 1987, 1988, 1998, 2004 and 2007.  Since climate change is a global crisis; therefore, we must act and work together to reduce Global greenhouse gas emissions and maintain global warming. Climate-resilient development, policies and plans Towards a low-carbon society and achieve the new global sustainable development goals (2016-2030) This will help reduce greenhouse gas emissions and the impact on water resources and water-dependent ecosystems.
