Grievance in the application was against apprehended damage to the environment by proposed activities during ‘Maru Mahotsav 2023’ at Jaisalmer from February 2 to 5, 2023. …
Desert dust perturbs climate by directly and indirectly interacting with incoming solar and outgoing long wave radiation, thereby changing precipitation and temperature, in addition to modifying ocean and land biogeochemistry. While we know that desert dust is sensitive to perturbations in climate and human land use, previous studies have been …
Emissions of African dust increased sharply in the early 1970s, but the human contribution to land degradation and dust mobilization remains poorly understood. Now, a 3,200-year record of dust deposition off northwest Africa has been constructed. On the basis of this dust record and a proxy record for West African …
Desertification is one of the most serious problems facing the world today. Large tracts of the dry areas that cover more than one third of the earth?s crust are being degraded or are in the process of degradation, posing serious threats to environment. These areas also include the most severe …
Plans to use concentrating solar power plants in the Sahara to generate and export electricity have been on the table for years. Now, it looks as though political will might help move things forward.
The aim of this forest policy is environmental stability and ecological security through increasing vegetal cover which will lead to reduction in soil erosion and consequently dust particle in upper stratosphere. The reduction in stratospheric temperature is likely to increase the possibility of rains. Increased sequestration of carbon from the …
There was a time when desert in India was synonymous with the Thar in Rajasthan. But the sands have flown across—unchecked and uncontained—and taken over parts of Haryana, Punjab, Uttar Pradesh and Madhya Pradesh as they advance by half a kilometre every year. There would soon be more contenders on …
The economic activities in Nigeria clearly show that over 60 percent of the population are engaged in agriculture for their livelihoods directly or indirectly. However overtime especially in the last decade, a dwindling state of agriculture and the decreasing number of farming population mostly in Northern Nigeria, known for the …
Desertification is the process of land degradation in arid, semi-arid and dry-subhumid areas. This communication describes the classification system, methodology and the results of desertification and land degradation status mapping carried out for the entire country on 1 : 500,000 scale using multi-temporal Resourcesat AWiFS data.
Free-ranging horses (Equus caballus) in North America are considered to be feral animals since they are descendents of non-native domestic horses introduced to the continent. We conducted a study in a southern California desert to understand how feral horse movements and horse feces impacted this arid ecosystem. We evaluated five …
In arid environments such as deserts, nitrogen is often themost limiting nutrient for biological activity. The majorityof the ecosystem nitrogen flux is typically thought to be drivenby production and loss of reactive nitrogen species by microorganismsin the soil. We found that high soil-surface temperatures (greaterthan 50
Global warming risks from emissions of greenhouse gases (GHGs) by anthropogenic activities have increased the need for the identification of ecosystems with high carbon sink capacity as an alternative mitigation strategy of terrestrial carbon sequestration. The agroforestry sector has received recent attention for its enormous potential carbon pools that reduce …
International space missions have found ice on the moon and more evidence of ice on Mars -- good news for future settlements and also for scientists looking for extraterrestrial life. Four reports published in Friday's issue of the journal Science show clear evidence of water, likely frozen, on the desert …
The problem of desertification sits at the interface of environmental and developmental concerns. In this article, we examine the institutional relationship between desertification science and policy through focus on the United Nations Convention to Combat Desertification (UNCCD) and its subsidiary body, the Committee on Science and Technology. We argue that …
Washington: Scientists are now seeing signals that the Sahara desert and surrounding regions are greening due to increasing rainfall, all thanks to the rising temperatures due to climate change. According to National Geographic News, these rains could revitalize drought-ravaged regions, reclaiming them for farming communities. This trend is supported by …
Diverting water from the Tigris and Euphrates rivers to supply agriculture, alongside a warming climate, means the once-bountiful region is becoming desert.
As the United States takes its first steps toward mandating that power companies generate more electricity from renewable sources, China already has a similar requirement and is investing billions to remake itself into a green energy superpower. Through a combination of carrots and sticks, Beijing is starting to change how …
- A project linking solar power from the Sahara to energy users in Europe and North Africa could create 240,000 German jobs and generate 2 trillion euros ($2,822 billion) worth of power by 2050, a study published on Thursday found. The report by Germany's Wuppertal Institute for Climate for Greenpeace …
