The ASTER Global Digital Elevation Model (GDEM) Version 3 (ASTGTM) provides a global digital elevation model (DEM) of land areas on Earth at a spatial resolution of 1 arc second (approximately 30 meter horizontal posting at the equator).
The development of the ASTER GDEM data products is a collaborative effort between National Aeronautics and Space Administration (NASA) and Japan’s Ministry of Economy, Trade, and Industry (METI). The ASTER GDEM data products are created by the Sensor Information Laboratory Corporation (SILC) in Tokyo.

The Institute for Marine Remote Sensing (IMaRS) at the University of South Florida (USF) was funded by the Oceanography Program of the National Aeronautics and Space Administration (NASA) to provide an exhaustive worldwide inventory of coral reefs using high-resolution satellite imagery. By using a consistent dataset of high-resolution (30 meter) multispectral Landsat 7 images acquired between 1999 and 2002, USF characterized, mapped and estimated the extent of shallow coral reef ecosystems in the main coral reef provinces (Caribbean-Atlantic, Pacific, Indo-Pacific, Red Sea).
In June 2007 a group of engineers, public health practitioners, local and international NGO staff, academics and government
representatives gathered to discuss water and sanitation in South East Asia and the Pacific at the Let's Come Clean Conference in Melbourne, Australia. At the conference, consensus emerged on the need for greater regional exchange of experience in sanitation. It was agreed that more could be done to document and disseminate practical lessons learned from water, sanitation and hygiene initiatives throughout the region.

Forests and other wooded land together cover about
one-third of the Asia and the Pacific region.
Excluding the Russian Federation, forest area in 2005
was estimated at 734 million hectares, accounting for
about 19 percent of global forest area. The region as a
whole experienced a net increase in forest area of about
633 000 ha annually during 2000-2005. This
is an important breakthrough, since the region had
experienced a net loss of forest cover during the 1990s. The improvement was largely the result of an increase of more
In World Resources 2005 we showed that ecosystems can become the focus of a powerful model for nature-based enterprise that delivers continuing economic and social benefits to die poor, even as it improves the natural resource base. Evidence shows that poor rural families empowered with secure resource rights can significantly increase their income stream from nature with prudent ecosystem management. To make this possible, a funda-
mental shift in governancein the power of the poor to access resources of value and build functional enterprisesis required.

The Earth currently finds itself in the midst of what some have termed the "Anthropocene Era" - a period during which human activities have become a dominate force affecting not only the
planet's landscape, but also its atmosphere. Since the dawn of the industrial evolution of the mid-18th century, humans have contributed to substantial increases in the concentration of
greenhouse gases in the atmosphere. Carbon dioxide has increased by 36%, methane by 17%, and nitrous oxide by 151%. These changes in the global atmosphere are directly linked to over
The Fourth Assessment Report of the IPCC (IPCC AR4) Working Group II (2007) identifies small island states as being among the most vulnerable countries of the world to the adverse impacts of climate change. Hay, el al.y (2003) in discussing the Pacific's observed climate noted that compared to earlier historical records during the twentieth century, the southern Pacific had experienced a significantly drier and warmer climate (by 15 percent and 0.8°C, respectively).
This remote chain of 13 islands (9 inhabited) and two atolls is located 140 south of the equator near the International Date Line. It is divided into two political entities, the US Territory of American Samoa and the neighboring independent country of Samoa, formerly known as Western Samoa. The land area of (western) Samoa is approximately 15 times larger than the land area of American Samoa
