Throughout October we will be focusing the blog on issues surrounding youth and sustainability. We will explore what young people around the world are doing to make their lives more sustainable, from small, individual actions to larger projects by school groups and coalitions of students. As part of this focus, we will try and highlight youth conferences and events worldwide that will be going on the rest of 2011 and throughout 2012, in the hopes that you may find a gathering of like-minded young people to share your ideas and interests on climate change. We are looking for suggestions of youth environmental programs to alert people to, so please post in the comment section if you know of an upcoming event or are part of such a group!

Before we delve into this topic further, let’s answer the question: What is sustainability? According to the United States Environmental Protection Agency (EPA),

Sustainability is based on a simple principle: Everything that we need for our survival and well-being depends, either directly or indirectly, on our natural environment. Sustainability creates and maintains the conditions under which humans and nature can exist in productive harmony, that permit fulfilling the social, economic and other requirements of present and future generations. Sustainability is important to making sure that we have and will continue to have, the water, materials, and resources to protect human health and our environment.

What does sustainability have to do with climate change? It turns out the two are very closely linked. From sustainable, clean energy sources (like wind and hydropower) that reduce our use of fossil fuels and Greenhouse Gas emissions, to sustainable building of cities as populations grow, to developing strategies for sustainable resource management that ensures continued access to clean water and trees. While governments, non-profit organizations and communities around the world are tackling these issues, there is also an incredible movement of youth taking action to ensure their own lives are as sustainable as possible. By looking forward to the future: access to things like food and water, temperature and sea level rise, the increase of extreme weather events, these young people recognize the need to take action today.

What do you do in your everyday life to be more sustainable?

September’s theme is…Water!

How are water and climate change related? What are the effects on water from climate change? To see the devastating effects with explanations in pictures, click here.

According to this water report by the Environmental Protection Agency (EPA), “The future effects of climate change on water resources… will depend on trends in both climatic and non-climatic factors. Evaluating these impacts is challenging because water availability, quality and streamflow are sensitive to changes in temperature and precipitation. Other important factors include increased demand for water caused by population growth, changes in the economy, development of new technologies, changes in watershed characteristics and water management decisions.” While climate change is not the only contributing factor to the future availability, safety and security of the world’s water resources, it is a major component that many governments are beginning to think about today.

Climate change will affect how much and when it rains, which in turn affects vegetation and agriculture, including soil moisture. This also means increased floods and droughts, loss of wetlands from rising sea levels, and an upset in the delicate balance of salinity in the world’s oceans, which will affect the millions of creatures who live in and/or depend on the ocean (including humans!)

Here is some additional information to give you a better understanding of who is affected by water issues today and who will be the most affected in years to come. In 2007, the Comprehensive Assessment of Water Management in Agriculture [1] stated that 1.2 billion people, or (at that time) about one-fifth of the world’s population lives in areas where water is physically scarce, and another 1.6 billion people live in developing countries without the ability to take water from rivers, aquifers and other water sources. Since 2007, the world’s population has increased – and so has the number of people without access to clean, safe water. This number will keep rising as the negative impacts of climate change continue. The alternative is that we do something to mitigate climate change…and come up with better solutions to adapt to it.

For more information on the science of how climate change affects water (flooding, drought, increased evaporation, natural disasters, etc.), check out http://www.climate.org/topics/water.html.

For water-related climate-risk management, here are the World Bank’s informational pages on water supply, sanitation and hygiene, agricultural water management, environmental services, hydropower, and water resources management.
