The research, published April 23 in Nature, is one of the most comprehensive observational studies to explore the effects of long-term drought on Congolese rainforests using several independent satellite sensors.Scientists use the satellite-derived \"greenness\" of forest regions as one indicator of a forest's health. While this study looks specifically at the impact of a persistent drought in the Congo region since 2000, researchers say that a continued drying trend might alter the composition and structure of the Congo rainforest, affecting its biodiversity and carbon storage.\"It's important to understand these changes because most climate models predict that tropical forests may be under stress due to increasing severe water shortages in a warmer and drier 21st century climate,\" Zhou said.Previous research used satellite-based measurements of vegetation greenness to investigate changes in the Amazon rainforest, notably the effects of severe short-term droughts in 2005 and 2010. Until now, little attention has been paid to African rainforests, where ground measurements are even sparser than in the Amazon and where droughts are less severe but last longer.To clarify the impact of long-term drought on the Congo rainforest, Zhou and colleagues set out to see if they could detect a trend in a satellite measure of vegetation greenness called the Enhanced Vegetation Index. This measure is developed from data produced by the Moderate Resolution Imaging Spectroradiometer (MODIS) instrument on NASA's Terra satellite. The scientists focused their analysis on intact, forested regions in the Congo basin during the months of April, May and June each year - the first of the area's two peak rainy and growing seasons each year.The study found a gradually decreasing trend in Congo rainforest greenness, sometimes referred to as \"browning,\" suggesting a slow adjustment to the long-term drying trend. This is in contrast to the more immediate response seen in the Amazon, such as large-scale tree mortality, brought about by more episodic drought events.The browning of the forest canopy is consistent with observed decreases in the amount of water available to plants, whether that's in the form of rainfall, water stored in the ground, water in near-surface soils, or water within the vegetation. || ", "hits": 77 }, { "id": 3967, "url": "https://svs.gsfc.nasa.gov/3967/", "result_type": "Visualization", "release_date": "2012-07-23T00:00:00-04:00", "title": "Deforestation in Rondonia, Brazil", "description": "In this animation of images from 1975 until 2012, acquired by the Landsat 5 and 7 satellites, enormous tracts of Amazonian forest disappear in Rondonia, a state in Western Brazil.Deforestation in Rondonia in the 1970s until the 1990s had a distinctive \"fishbone\" pattern. Access to this remote region began with a major road cutting through the dense tropical forest, opening up new territory for small farms and ranches. Then, other roads developed at right angles to the initial road. In this visualization, these roads shoot off a stretch of the main \"backbone\" road for about 31 miles (~50 kilometers) long, each secondary road branching off about every 2.5 (~4 kilometers). This creates the \"fishbone\" pattern. Even with the deforestation, Brazil is still home to more than a quarter of Earth's tropical forests. In addition to their astounding biodiversity, these forests act as a major carbon \"sink.\" These are places where carbon dioxide in the atmosphere is absorbed by living things, like trees and plants, and thus the carbon is said to be trapped or sequestered. With increasing carbon dioxide levels around the world, the ability of these forests to hold onto carbon has beneficial implications for stabilizing the world's climate.NASA and the U.S. Department of the Interior through the U.S. Geological Survey (USGS) jointly manage Landsat, and the USGS preserves a 40-year archive of Landsat images that is freely available over the Internet.

Forests have never been under more pressure. Demand for their natural wealth and a hunger for land causes forest clearance at alarming rates. The UN Food and Agriculture Organization (FAO) estimates that the Earth loses an area about the size of a football field every 3 seconds - in the time it takes to make a sandwich an area equivalent to the National Mall in Washington, D.C., is cleared... somewhere on Earth trees are falling every second of every day. Based on a systematic sample of Landsat imagery at 4,016 locations around the tropical belt the European Commission's TREES 3 project is making estimates of forest cover change for the years 1990, 2000, 2005 and 2010 with new levels of precision. Preliminary results emphasize just how relentless the pressure on our planet is. Using archived and recent Landsat imagery we have measured dramatic changes to the African Continent for example. Since the 1970s natural vegetation (forests and savannas) have been converted to agricultural land at a tremendous pace. Around 50,000 sq. km per year are cleared - an area twice the size of Vermont. With the fastest growing population in the world such land cover conversions are unlikely to slow down any time soon, nor should the measuring programs. Landsat 8 and its European counterpart, Sentinel 2, are not being launched any sooner than they are needed. || ", "hits": 141 }, { "id": 3842, "url": "https://svs.gsfc.nasa.gov/3842/", "result_type": "Visualization", "release_date": "2011-06-24T00:00:00-04:00", "title": "Carbon Catch And Release", "description": "Through tiny, microscopic pores called stomata, plants absorb one hundred billion tons of carbon from the air each year and convert about half of that into organic matter—leaves, roots, tree branches, grass.

NASA has closely measured this since 2000, and that volume of absorption is seen in the first visualization below as waves of green. The northern hemisphere all the way up to the Arctic Circle swells with life each summer, before much of the vegetation wilts and exhales its carbon in fall and winter.
