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).

From 2001 to 2017, Papua New Guinea lost 1.28Mha of tree cover, equivalent to a 3.0% decrease since 2000, and 158Mt of CO₂ of emissions.
This book aims to make a contribution to the understanding of the current system of global environmental governance, its
strengths and weaknesses, and the options and opportunities to achieve much needed reform.

France has an important role and extensive responsibilities in protecting the world's oceans. It is the world's third
largest maritime power with an Exclusive Economic Zone (EEZ) covering 11 million km2, and has the fourth
largest area of coral reefs representing biodiversity hotspots.
According to a recent Nature Conservancy assessment, only 1% of marine areas (as against 12 % of all land
areas) are officially protected today, despite government commitments under the UN Convention on Biological

The GEF and UNCCD Secretariats collaborated on this new book to convey how sustainable land management (SLM) practices are helping shape a sustainable future for people and the planet. The book is illustrated with high quality photos donated by the GoodPlanet Foundation and from other sources, to demonstrate how human ingenuity is largely driving innovations in soil, land, water, and vegetation management.
With these decisions in mind, the Pacific Plan identifies initiatives within an implementation framework that extends to 10 years. Some of this work is already underway. The Plan provides a framework for effective and enhanced engagement
between Forum countries and Pacific territories and with their non-state actors and development partners. It does not limit the sovereign right of Forum Member countries to determine their own national goals and priorities. It may also guide but does not restrict bilateral development programmes and activities.

Ice, snow and climate change are closely linked. The Global Outlook for Ice and Snow investigates those linkages. It also presents information on the trends in ice and snow, the outlook for this century and beyond and the consequences to ecosystems and human well-being of these changes. It covers all parts of the cryosphere (the world of ice): snow, land ice, sea ice, river and lake ice, and frozen ground. The Global Outlook for Ice and Snow was written by more than 70 scientists from around the world.
