Water resources, and the range of services they provide, have a great importance, they underpin environmental sustainability, poverty reduction and economic growth. Water is essential for life, for human and environmental health, producing food in agriculture, energy security. Water contributes to improvements in social well-being and inclusive growth, affecting the livelihoods of billions.
22th of March is an international environmental world day, the world water day since 1992, which was decided by UN. In 2000 UN established 8 Millennium Development Goals to reach by 2015. The 7th is about ensuring environmental sustainability. There are several aspects of this, but it underlines the importance of water security in Target 7c: “Halve, by 2015, the proportion of the population without sustainable access to safe drinking water and basic sanitation.”
UN Water‘s video for World Water Day 2015 represents the importance of water in all aspects of human life.
Climate change, fast growth of population and overconsumption threaten drinking water scarcity in more and more areas. People use lots of water for drinking, cooking and washing, but even more for producing things such as food, paper, cotton clothes, etc. The water footprint is an indicator of water use that looks at both direct and indirect water use of a consumer or producer. The water footprint of an individual, community or business is defined as the total volume of freshwater that is used to produce the goods and services consumed by the individual or community or produced by the business. Due to climate change the amount of freshwater is reduced.
World water day draws attention to that in order to protect water resources and ensure water sustainability far all it is necessary to decrease water consumption as much as it is possible, we have to care about water quality, water treatment and slow down climate change by cutting down greenhouse gas emission like carbon dioxide and methane. Every steps and activities for cutting down CO2 helps water related topics at the same time. We have to reduce not only water footprint but carbon footprint too for a sustainable water management .
