Forecast Mekong Video Released

The great deltas of the world are among our most heavily populated and agriculturally productive landscapes, yet these low-lying coastal areas are extremely vulnerable to climate change and development impacts. An international challenge is to transform these vulnerable ecosystems to resilient ones. Through comparative studies and ecological forecasting, such as what is being done with the Mississippi and Mekong Rivers, we can work towards balancing natural landscape functions with economic development to produce healthy ecosystems and sustainable deltas.

The video below is a form of science diplomacy requested by the U.S. Department of State to educate policy-makers and citizens in Southeast Asia about the vital importance of the Mekong river and delta in maintaining food security and livelihoods in the region. The video also seeks to make policy-makers aware of the potential impacts of climate change on people and the environment of the Mekong delta.

A Different Delta Force – USGS and U.S. Department of State Assist in Mekong Delta

Satellite Image of the Mekong and Mississippi River Deltas The U.S. Geological Survey is bringing its broad scientific understanding of the Mississippi Delta to bear on a similar river delta a half a world away, the Mekong River Delta of southeast Asia. Through the U.S. government’s Lower Mekong Initiative, the USGS Delta Research and Global Observation Network (DRAGON) partnership will use its experience with the Mississippi River and its expertise in earth science modeling to help the Mekong countries assess how climate change and human activities could impact the ecology and food security of the Mekong basin.  More...

DRAGON Expands with “Forecast Mekong”

On July 23, 2009, in Phuket, Thailand, USGS scientists met with U.S. Secretary of State Hillary Rodham Clinton and the foreign ministers from Cambodia, Laos, Thailand, and Vietnam to view a video on “Forecast Mekong.” This first-ever group meeting of the Secretary and the ministers highlighted the increasing cooperation between the United States and Lower Mekong countries in the areas of environment, health, education, and infrastructure development.

Part of the Delta Research and Global Observation Network (DRAGON) Partnership, “Forecast Mekong” is an interactive data integration, modeling, and visualization system to help policy makers, resource managers, and the public understand and predict outcomes from climate change and development projects in the Mekong River Basin. When fully developed by the USGS, in partnership with local governments and universities throughout the Mekong region, the Forecast Mekong program will provide a valuable planning tool to visualize the consequences of climate change and river management.

The United States will spend more than $7 million in 2009 on environmental programs in the Mekong Region, and the Forecast Mekong effort will be among the funded programs.

DRAGON Asia Summit 2009: A Huge Success

The purpose of the DRAGON Asia Summit was to forge new global partnerships to develop the science needed to inform decision making in the Mekong, Mississippi, and other large river and delta systems around the globe. The 2009 DRAGON Asia Summit took place June 22 – 25 in Siem Reap, Cambodia, and was attended by more than 130 scientists from 11 nations, two U.S. ambassadors, and three ministers from Cambodia. During the Summit, information, data, and tools were presented in 23 plenary presentations and in 54 technical presentations. Pre-conference short courses on knowledge integration and mapping and on climate change were also offered, as well as a field trip to the dynamic Tonle Sap Lake.

The DRAGON Partnership has grown tremendously because of this gathering of scientists, policymakers, and natural resource managers. The work performed at the Summit provides the partnership with an expanded network and direction for the future and supports a scientific approach to addressing the issues challenging the planet’s dynamic delta ecosystems.

Upstream Dams 'Threaten Mekong'

Reported by Radio Free Asia

Vietnamese environmental experts have sharply criticized plans by Laos, China, and Thailand to build a cascade of dams along the upper reaches of the Mekong River, which flows through six countries, including Vietnam.  More...

Vietnam starts $112 million climate change program

Reported by Mai Vong, Thanh Nien News

Vietnam’s environment agency formally launched its VND 1.96 trillion (US $112.44 million) program to protect the country from the effects of climate change on Monday 12 January 2009. Scientists from the US and Vietnam will study the impact of climate change on the Mekong Delta and other low-lying river regions around the world. Gregory Smith, head of the National Wetlands Research Center of the US Interior Department, said the aim of the joint study is to gather large-scale data sets to help model the impact of rising sea levels and worsening cyclonic storms on river deltas, man-made structures and communities.  More...
