Plant rooting and growing in the Groasis Waterboxx. The Groasis Waterboxx is a device designed to help in growing trees in dry areas. It was invented and developed by Dutch former flower exporter Pieter Hoff, [1] and won the Popular Science Green Tech Best of What’s New Innovation of the year award for 2010.
A satellite image of the Sahara, the world's largest hot desert and third largest desert after Antarctica and the Arctic. Desert greening is the process of afforestation or revegetation of deserts for ecological restoration (biodiversity), sustainable farming and forestry, but also for reclamation of natural water systems and other ecological systems that support life.
A liman created by the JNF in the Negev Desert. A Liman (from Greek λιμήν) in Israel is the name for an artificial earthen construction used to collect floodwater by damming a desert wadi. The runoff water is slowed by the dam, thus flooding a small area and allowing the water to infiltrate into the soil. This way, a small groves of trees ...
Namib Desert beetles live off water that condenses on their wings due to a pattern of alternating hydrophilic (water attracting) and hydrophobic (water repelling) regions. Redwood forests are able to survive on limited rainfall due to the addition of condensation on needles which drip into the trees' root systems. [3]
In drier conditions, the bunds are larger, whereas in wetter areas, more bunds with smaller radii are built. Larger, more widely spaced half-moons are primarily used for rehabilitating grazing land or producing fodder, while smaller, closely spaced half-moons support the growth of trees and shrubs. [10]
The plants remove about seven to ten percent of pollutants, and act as a carbon source for the microbes when they decay. Different species of aquatic plants have different rates of heavy metal uptake, a consideration for plant selection in a constructed wetland used for water treatment. Constructed wetlands are of two basic types: subsurface ...
Ecologists across the Southwest are working to figure out how different species respond to the onslaught of heat year after year and just how hot is too hot for desert plants and trees.
An example for water purification as an ecosystem service is as follows: In New York City, where the quality of drinking water had fallen below standards required by the U.S. Environmental Protection Agency (EPA), authorities opted to restore the polluted Catskill Watershed that had previously provided the city with the ecosystem service of ...
