Sowing a future for peas
New research from the John Innes Centre and the Central Science Laboratory could help breeders to develop pea varieties able to withstand drought stress and climate change. view more (2008-09-17)
Crossing paths in plants
On Monday 31 March ecologists will meet with molecular biologists at the University of Southampton for the most novel and broad-ranging scientific session of its kind. They will present findings in Session C5/P3 which show that the biochemical pathways which influence a plant's response to stimuli such as attack, disease or other stresses are not... view more...

Time of day matters to thirsty trees, U of T researcher discovers
The time of day matters to forest trees dealing with drought, according to a new paper produced by a research team led by Professor Malcolm Campbell, University of Toronto Scarborough's vice-principal for research and colleagues in the department of cell and systems biology at the St. George campus. view more (2009-11-24)
Sequence matters in droughts and floods
When extremes of drought and flood come in rapid succession, the extent of damage to vegetation may depend in part on the sequence of those events, according to a new study published in The American Naturalist. view more (2009-01-08)
Research finds way to double rice crops in drought-stricken areas
University of Alberta research has yielded a way to double the output of rice crops in some of the world's poorest, most distressed areas. view more (2008-11-21)
Drought sensitivity shapes species distribution patterns in tropical forests
Looking at a rainforest it's easy to see that there are hundreds of different tropical plant species that inhabit the forest. Although the patterns of plant distributions in tropical forests have been widely studied, the reasonings behind these patterns are not as well known. view more (2007-05-15)
Drought limits tropical plant distributions, scientists at the Smithsonian report
Drought tolerance is a critical determinant of tropical plant distributions, researchers working at the Smithsonian Tropical Research Institute in Panama report in the journal Nature, May 3. view more (2007-05-03)
Salt of the Earth
A yeast gene responsible for salt tolerance has successfully been used to grow tobacco in a salty environment lethal to most plants. Dr Janey Henderson and Professor Phil Harris from Coventry University inserted the halotolerance gene HAL1 from yeast into a tobacco plant. HAL1 has previously been shown to confer salt tolerance in transgenic tomato... view more... (2001-04-04)
Beavers can help ease drought
They may be considered pests, but beaver can help mitigate the effects of drought, and because of that, their removal from wetlands to accommodate industrial, urban and agricultural demands should be avoided, according to a new University of Alberta study. view more (2008-02-21)
Breakthrough in environmental monitoring from space
Scientists working at the Joint Research Centre of the European Commission have developed a new way to interpret data from satellites observing the earth. The satellites monitor the nature, state and evolution of the earth's vegetation. This enhanced monitoring capacity will make it more possible to determine the impact of major climatic events,... view more... (2004-12-17)
Drought tolerance in potatoes
Climate change is expected to exacerbate drought events throughout the world, resulting in large-scale ecosystem alteration and failure of drought-sensitive crops. view more (2008-06-30)
Amazon forest shows unexpected resiliency during drought
Drought-stricken regions of the Amazon forest grew particularly vigorously during the 2005 drought, according to new research. view more (2007-09-24)
Drought resistance explained
Much as adrenaline coursing through our veins drives our body's reactions to stress, the plant hormone abscisic acid (ABA) is behind plants' responses to stressful situations such as drought, but how it does so has been a mystery for years. view more (2009-11-10)
Why juniper trees can live on less water
An ability to avoid the plant equivalent of vapor lock and a favorable evolutionary history may explain the unusual drought resistance of junipers, some varieties of which are now spreading rapidly in water-starved regions of the western United States, a Duke University study has found. view more (2008-02-28)
MONSOON IN WEST AFRICA:CLASSIC CONTINUITY HIDES A DUAL-CYCLE RAINFALL REGIME
Since the end of the 1960s West Africa has continuously been suffering hard drought. The rainfall deficit for the 1970s and 1980s, calculated to compare with the 1950s and 1960s, thus reached as high as 50% over the northern part of the Sahel. The hydrological cycle as a whole is affected by this drought, which results in serious consequences for... view more... (2003-01-28)
Why UK households should splash out on water meters

Livestock interventions can protect lives, livelihoods
Pastoralist communities in dryland areas of Africa are reliant on livestock as sources of food, income and social support. However drought is common in sub-Saharan Africa, making these communities vulnerable to loss of livestock when rains fail. view more (2007-04-24)
Saltwater solution to save crops
Technology under development at the University of New South Wales could offer new hope to farmers in drought-affected and marginal areas by enabling crops to grow using salty groundwater. view more (2008-09-12)
Global warming aided by drought, deforestation link
In the rainforests of equatorial Asia, a link between drought and deforestation is fueling global warming, finds an international study that includes a UC Irvine scientist. view more (2008-12-09)
Congo River Basin : Geology And Soil Type Influence Drought Impact
The Congo drainage basin is situated in Central Africa. Its hydrological system straddles several countries (Congo and the Democratic Republic of Congo for the most part, but also Angola, Cameroon, the Central African Republic, Zambia and Tanzania, stretching through Lake Tanganyika). The River Congo, the second longest African river after the... view more... (2002-01-03)
