Global Innovation Exchange Co-Created by Horizon International, USAID, Bill and Melinda Gates Foundation and Others

Horizon International co-created the Exchange alongside USAID and organizations from across government, business, academia, and NGOs who believe that together we can tackle humanity’s greatest challenges.  The Exchange is providing over 300 summaries of resources from Horizon’s Solutions Site with links to the full articles and case studies and anticipates to soon have over 600 posts from the Solutions Site’s 1,500 plus resources.  Explore resources on the Exchange from Horizon International at






Wildlife Preservation in Southeast Nova Scotia

The efforts of the Clean Annapolis River Project lead to preservation of the Annapolis River and its watershed in Nova Scotia, Canada, and its designation as a UNESCO Biosphere Reserve.

Urbanization Provides Opportunities for Transition to a Green Economy, Says New Report

“Integrating the Environment in Urban Planning and Management: Key Principles and Approaches for Cities in the 21st Century,” a report launched on 8 April 2014 jointly by the United Nations Environment Programme (UNEP) and Cities Alliance at the 2014 World Urban Forum in Medellin, Colombia, says that as consumers of over 75% of natural resources, cities can be major contributors to efficiency and sustainability.

The Effects of Population on the Depletion of Fresh Water

This article compares quantitative estimates for groundwater loss and glacier recession and considers the significance of their relative magnitudes. It concludes that the effect of food and agriculture, hence of population, may be significantly greater than that attributable to the global warming caused by industrial production and transport.

NASA Launching Five Earth-Observing Missions in 2014 to Obtain Crucial Data for Scientists Trying To Understand Our Changing Planet

With the launch of five Earth-observing missions in 2014 -- more Earth-focused launches in a single year in more than a decade -- NASA will be able to deliver even more crucial data to scientists trying to understand our changing planet.

NASA’s OCO-2 Brings Sharp New Focus on Global Carbon

. In July 2014, NASA will launch the Orbiting Carbon Observatory-2 (OCO-2) to study the fate of carbon dioxide worldwide. Natural processes are working hard to keep the carbon cycle in balance by absorbing about half of our carbon emissions, limiting the extent of climate change. There's a lot we don't know about these processes, including where they are occurring and how they might change as the climate warms. To understand and prepare for the carbon cycle of the future, we have an urgent need to find out.





Modeling Disease Outcomes to Help Meet Challenges of Infectious Diseases and Climate Change

Climate change is already affecting the spread of infectious diseases--and human health and biodiversity worldwide--according to disease ecologists reporting research results in the August 2, 2013 issue of the journal Science. Modeling disease outcomes from host and parasite responses to climate variables, they say, could help public health officials and environmental managers address the challenges posed by the changing landscape of infectious disease.

Harvard Scientists Find Changing Atmosphere Affects How Much Water Trees Need

Increasing levels of atmospheric carbon dioxide alter how plants use water: Spurred by increasing levels of atmospheric carbon dioxide, forests over the last two decades have become dramatically more efficient in how they use water. "Findings from this study are important to our understanding of forest ecosystems--and how they can be managed more effectively now and in the future."

Oyster 800 Wave Machine Endures Massive Waves in Scotland

The footage was captured on April 23 this year, and shows Oyster 800 in waves over eight metres high at the European Marine Energy Centre in Orkney. "The big challenge in designing and building a wave machine is ensuring it can survive in massive waves. The video gives a good example of what we need to design for," says Aquamarine Power Chief Executive Officer Martin McAdam.

How To Reduce Environmental and Human Health Impacts of Development

How the built environment, the way we build our cities and towns, directly affects our environment and public health is considered in a comprehensive U.S. Environmental Protection Agency report released on June 17, 2013. The report and associated resources offer advice on how to reduce environmental and human health impacts of development.
