Forests Near or Far Can Protect Water for Cities

Forests Near or Far Can Protect Water for Cities

Near or far, forests — like this one at the edge of Hong Kong — affect the movement, quality and availability of water in cities. Photo by Florian Wehde/Unsplash

Water is essential to human health and well-being. In cities, leaders strive to provide secure access to clean, safe and affordable water. In rural areas, farmers hope for adequate rain and healthy rivers to produce healthy crops. The coronavirus pandemic reminds … [more…]

Water, not temperature, limits global forest growth as climate warms

Graphic: 'heat map' showing stressorss

Chart: The growth of forest trees in temperate and boreal regions became more limited by water rather than temperature as the 20th century warmed. The more orange-red the area on the map, the more tree growth in that region became limited by water availability. The bluer the area, the less water-limited the trees became.

Resilient forests host trees with a diversity of water-use strategies

Diversity is strength, even among forests. In a paper published in Nature, researchers led by University of Utah biologist William Anderegg report that forests with trees that employ a high diversity of traits related to water use suffer less of an impact from drought. The results, which expand on previous work … [more…]

How planting trees and grasses can help stabilise farmland in a changing climate

Certain native species, such as Eucalyptus populnea, can combat the effects of drought. As parts of the country face the toughest drought in people’s lifetimes, tree species that can assist in water and soil management have a renewed purpose.

Need to raise your water table, stabilise your soil or grow an alternate fodder source in arid conditions? There is a tree — or grass — for that.

The world is facing a growing water crisis: already, 40 percent of the world’s population are affected by water scarcity, and climate change threatens to increase the frequency of both floods and droughts in vulnerable areas around the world.

A new report released recently at the United Nations High-Level Political Forum on Sustainable Development in New
