The second objective was to use the evaluated modules to assess the long - term effects of growing winter wheat as a cover crop on water balances and seed cotton yield under irrigated and dryland conditions, Ale said.
The two DSSAT crop modules were evaluated using measured data on soil water and crop yield from four treatments: irrigated cotton without a cover crop, irrigated cotton with winter wheat as a cover crop, dryland cotton without a cover crop, and dryland cotton with a winter wheat cover crop at the Texas A&M AgriLife Research Station at Chillicothe from 2011 to 2015.
Although dryland producers — those who grow crops without irrigation — are more vulnerable in times of drought, many irrigators are gazing warily at dropping water tables.
Alexander also noted that the implications of the study have the potential to benefit not only Botswana, but dryland systems globally.
The vast majority of dust - producing regions are drylands.
The variables of interest include legume species, location, such as tropic or non-tropic, climatic region, such as dryland or non-dryland, drought timing, and soil texture.

Given the predicted changes to dryland habitats globally, the outcome of this research is essential for developing strategies for adaptation by policy makers.»
The certainty of the forecasts is particularly important as warming leads to shifts from temperate to subtropical drylands, which leads to changes in precipitation and soil moisture, which in turn has profound effects on ecological services, provided to humanity, including the viability of certain temperate agricultural systems.
Projected global warming will likely decrease the extent of temperate drylands by a third over the remainder of the 21st century coupled with an increase in dry deep soil conditions during agricultural growing season.
«For example, with the expansion of subtropical drylands as temperate drylands warm cool season crops such as wheat and potato would no longer be economically viable,» says Scott Wilson.
«Further, these subtropical drylands are home to aggressive diseases such as dengue and schistosomiasis.
This map shows forested (green) and nonforested (yellow) dryland regions in 2015.
COUNTING TREES Researchers analyzed Google Earth imagery of dryland forest plots (one example of an open baobab forest in Senegal, shown) to reveal millions of forest hectares not previously reported.
This is good news: Drylands cover almost 42 percent of Earth's land surface, and climate change could expand the parched zones by 11 to 23 percent by 2100.
They report that drylands with termite mounds can survive on significantly less rain than those without termite mounds.
In the parched grasslands and savannas, or drylands, of Africa, South America and Asia, termite mounds store nutrients and moisture, and — via internal tunnels — allow water to better penetrate the soil.
Princeton University researchers report in the journal Science that termites slow the spread of deserts into drylands by providing a moist refuge for vegetation on and around their mounds.
«That subjects rice to a different spectrum of disease, weeds and insect pests than dryland or irrigated crops.»
The termite - mound pattern, however, looks deceptively similar to the last and most critical of the five stages that mark the transition of drylands to desert, Tarnita said.
But these mechanisms are not necessarily mutually exclusive in drylands, Tarnita said.
Drs Singer and Michaelides employ STORM to show that the historical rainfall trends likely resulted in less runoff from this dryland basin, an effect they expect to have occurred at many similar basins in the region.
To explore the links between climatic warming and rainfall in drylands, scientists from the Universities of Cardiff and Bristol analysed more than 50 years of detailed rainfall data (measured every minute) from a semi-arid drainage basin in south east Arizona exhibiting an upward trend in temperatures during that period.
Until now, no research has been undertaken that examines this relationship in dryland regions where short, sharp rainstorms are the dominant source of precipitation and where moisture availability on land is extremely limited.
Their new estimate of dryland forest is 40 to 47 % higher than previous estimates, corresponding to 467 million hectares (Mha) of forest that have never been reported before.
Lead author, Dr Michael Singer from School of Earth and Ocean Sciences at Cardiff University, said: «In drylands, convective (or short, intense) rainfall controls water supply, flood risk and soil moisture but we have had little information on how atmospheric warming will affect the characteristics of such rainstorms, given the limited moisture in these areas.»
Since trends in convective rainfall are not easily detected in daily rainfall records, or well - simulated by global or regional climate models, the researchers created a new tool to assess the effects of climate change on rainfall patterns and trends in dryland areas.
