The focus of this section, will be collection and analysis of the data for the two RQs. First, I will state the needed data for each RQ, potential sources and process of analyzing it. For instance, estimation of desertified area or ESAs (Environmentally Sensitivity Areas) (11) for each year –1994, 2004 and 2014 – will be based on four indicators (NDVI, Albedo, Soil moisture and Sand dunes). The selection of these indicators based on many studies. For instance, the selection of the best indicators to monitor and assess the desertification in arid and semiarid region seen a lot of evolution. For the OECO the desertification is process of pressure, state and response (PSR) while the FAO, UNCCD and European commission for dry land (12) look the desertification process as results of five steps: Driving forces, pressure, state, impact and responses (DPSIR). …show more content…
For this case study, I selected these indicators because they met indicator evaluation criteria for UNCCD (15) and the SMART concept – Specific, Measurable, Achievable, Relevant and Time-related. The indicators estimation will depends on the Remote Sensing (RS) data. As explained in (16a), the RS (Landsat) data is suitable for quantification of spatio-temporal desertification or (ESAs) because it allows researcher to go back and examine the change. Here, I should mention that desertification is a slow process which takes years to happen (17a). For the RS data, I will request the Landsat data for Biskra for three years. (1994, 2004 and 2014). The RS imagery will be preprocess it in order to get a maximum accuracy. The preprocess mean will be ERDAS imagine software and possible GIS

227 Words | 1 PagesThe power spectral densities ($PSD$) of the gas jet centerline $C^*(t)$ for the tests in Tab.\ref{Table} were computed via $FFT$, and collected in Fig.\ref{Spectra}. For plotting purposes, the frequency domain $f_j$ is limited to $f_j=150 Hz$, and the $PSD$ in each graph is normalized with respect to the maximum $PSD$ detected within the three tests. Regardless of the stand-off distance $\hat{Z}$, for $\hat{Y}=0$ the response of the jet to the membrane motion is the superimposition of a harmonic response $f_h$ and a higher frequency $f_f$, which is not affected by the membrane motion. Noteworthy, $f_f$ scales with the standoff distance and leads to a constant Strouhal number $St_Z= f_f Z/U_j\approx 0.08$, not far from the $St_Z=0.12$ \cite{Vshape}

The climate data from the Mojave Desert had a network of weather stations. Two precipitation patterns were blue: 70% of stations west of 117 degrees and red: 90% of stations east of 117 degrees. There were diverse landforms on foot to meter scale.

Effects Of Overgrazing On Soil
1327 Words | 6 PagesThis is because the higher demand for food and fuel causes the removal of protective vegetation from the area, meaning that rain-splash erosion and aeolian erosion can occur. The chance of desertification increases when an area is experiencing drought conditions. This is because the soil is already stressed by the processes of overcropping and overgrazing, and so a drought dries out the soil completely and causes it to become useless and desertified.
The Impact Of The OCO-Two
992 Words | 4 PagesPreviously, devices were not able to measure the levels of carbon distribution in such territories due to the terrains in such regions (NASA.gov). This limited how researchers could understand the changes that occurred in the region. These changes included the decreasing ice layers which have been associated with global warming and climatic changes in the region. However, there has been no accurate information on how the melting ice affected the already existing Carbon Dioxide levels especially due to the ability of large masses of water to absorb the gas. d) The data received from the OCO-2 has also contributed in understanding how various elements such as weather fronts, storms, and hurricanes affect the carbon cycle.
Sahara Desert Essay
759 Words | 4 PagesGeographical process: The Atmospheric process links to the climate in the Sahara desert because of the prevailing wind, which blows from the northeast towards the equator throughout the year, this accounts for the deserts aridness. When the wind moves southwestward, the air warms which results in it releases rainfall because the humidity. The Biotic process is linked with the sahara desert because Desert animals have made adaptations as well as plants, even their features and behavior have adapted to the Sahara Deserts conditions. Some examples of animals that have adapted to the desert are camels, scorpions, birds and spotted hyena, the plant that has also adapted to the Sahara Desert is the welwitschia plant because of its long roots that reach as much water as possible.

How To Survive A Hot Desert Essay
1082 Words | 5 PagesDeserts cover 20 percent of the earth’s land surface, which is close to thirty million square miles. Deserts are large and dry regions that receive very little amount of rainfall per year, have a lot of bare soil and low vegetation cover. Despite the common misconception of all deserts being dry and hot, there are cold deserts as well. Areas covered in ice or snow, with limited vegetation plantation, are sometimes called 'cold deserts '. However, in this essay, we will be discussing on survival in hot desert.
Deserts And Climate Change
1558 Words | 7 PagesDeserts are one of the most affected ecosystems by climate change. Most desert are likely to become more extreme due to the foreseen climate change, and any solutions will depend largely on the human management (Noble & Gitay, 1996). Deserts and semi-deserts are predicted to be one of the most responsive of the world’s ecosystem types under the current increase of carbon dioxide (CO2) in the atmosphere and related global climatic changes (Lioubimtseva, Elena, & Adams, 2004). According to many environmental models used for climate change forecasting, the climate change has a wide range of direct and indirect impacts on humans, animals, vegetation, and even sometimes on the future behavior of the climate change itself. However, in the spite of
