Our water supply is finite. From areas of abundance to places struck with drought, ensuring access to a clean, reliable source of water is critical.
World Water Day is an international observance and an opportunity to learn more about water related issues, be inspired to tell others and take action to make a difference. World Water Day dates back to the 1992 United Nations Conference on Environment and Development where an international observance for water was recommended. The United Nations General Assembly responded by designating 22 March 1993 as the first World Water Day. It has been held annually since then.
Maps help us protect water supplies and their integrity by understanding how human behaviors impact the natural system, document water sources and quantify their capacity based on current and historic data, and then share the story of the water system through engaging maps so everyone can see how today’s actions affect tomorrow’s water system.

With all the recent excitement and good hopes over the White House Climate Data Initiative, and the ongoing progress of the Global Earth Observation System of Systems (GEOSS), there is another huge data initiative that bears mention: EarthCube.
I have used the word “initiative” for EarthCube but it has also been described as a vision, as a multi-faceted, multi-layered partnership, and also as a “virtual organization.” As such, it bears quite a bit of resemblance to the international GEOSS, but is much more US-based, having been conceived and currently funded by the US National Science Foundation (NSF).

The goal of sustainable planning, policies, and governance is to design processes that return our planet to a more balanced level of use. To do so we must realign our values and earth’s ability to support them. The success of this effort is dependent upon a foundation of science, a means of collaboration, and the implementation of sustainable polices and administration. GIS is an essential tool for designing and implementing sustainable processes at a scale ranging from local to global.
People around the world continue to compile scientific data about resources, ecosystems, and human impact. GIS enables us to visualize and analyze these massive collections of data. Establishing a base for determining cause and effect, GIS tracks ecological change and provides chains of evidence of human impact. It tracks people’s land use, methods of resource extraction, and peripheral activities, such as supporting road networks. GIS manages large databases, depicts and prioritizes problems, models scenarios of both positive and negative practices, and predicts environmental outcomes. It provides the quantified information and analytical capabilities required for making location-based decisions that increase economic efficiencies and reduce consumption and contamination.
What have we learned after 100 years?
On April 15, 1912, more than 1,500 passengers and crew aboard the RMS Titanic perished at sea in one of the most infamous maritime disasters in all of human history. She was the largest ship afloat at the time, but the location of her wreckage remained a mystery until 1985. Many have seen similarities between the sinking of Titanic and the struggles of the gigantic cruise ship Costa Concordia, which ran aground off the coast of Italy almost 100 years later.

Climate Change Is a Geographic Problem
Reducing the risks caused by climate change is an immense challenge. Scientists, policy makers, developers, engineers, and many others have used GIS to better understand a complex situation and offer some tangible solutions. Technology offers a means to assess, plan, and implement sustainable programs that can affect us 10, 20, and 100 years into the future. Continue reading
