The aim of this research paper is to investigate the land cover changes in Sudan during period 2001-2013 by using MODIS data and identify climatic factors influencing cover. SPSS v 17 software was used correlation with vegetation cover; also ArcGIS 10.2 analyze NDVI data. results indicate that monthly average time scale, value curve distribution year, July October as center both sides decreasing other months. In spatial mean Sudan, a high found southern part. On hand, low northern spaces...
The Qinghai Province, situated in the northwest of China, is experiencing a continuous warming which approximately three times more than rate global warming. This ongoing has direct connection to vegetation cover, with significant societal and economic impacts this region. In present study, we investigate correlation between climate change cover Province. Analysis shows that order NDVI highest summer followed by autumn, spring winter. By calculating average annual seasonal-NDVI values, it...
The main objectives of this study were to detecting the land use and cover change (LULC), using remote sensing techniques, then identify reasons for rangeland tree degradation in El Rawashda Forest, Gadarif State, Sudan. has conducted field experiment developed on an area 20 feddans that was affected by deterioration forest assess best method rehabilitation vegetation study. experimental divided into 5 blocks; each block consisted 4 treatments: grass seeds Talih (Acacia seyal var. seyal);...
The aims of this research were to investigate the impacts climate variations on land use policies, food security and vegetation cover in Gadarif State (eastern Sudan) during 1961 2013. Analysis precipitation temperature time series revealed that annual was decreasing while increased study area. Precipitation at a rate −50.3 mm/10a, increasing 0.02°C/10a. result both SPEI SPI showed has been changed high frequency drought 1961-2013. Sorghum yield significant positive relationship with July...
Climate change scenarios project that several regions, especially in dryland areas of sub-Saharan Africa, will undergo increasing aridity and, subsequently, expanding land degradation. The study aims to investigate the effect two drying treatments on establishing and growing Hashab (Acacia senegal) Boabab (Adansonia digitata) nursery conditions. Through a 2×2 factorial experiment, seedlings grown mixture silt sand soil (2:3) were treated by irrigation intervals one or liters every three days...
We carried out this research at Abu-Gaddaf Natural Forest Reserve (ANFR) which is located east of Blue Nile River, in State, Sudan. It aims exploring tree composition assessing their diversity indices, and ecological importance values. For survey types estimation density species the forest, we randomly distributed 97 circular sample plots (0.1 hectare (ha)). In each plot identified all trees to level, recorded frequencies computed value indices (IVI). A total 13 species, belong 12 genera...
The aim of this study is to investigate the impact temperature trend on glacier-mass balance, snow density, snowmelt, depth and runoff by using observations nine glacier stations that covered most China over period 1979-2013. Trend analysis showed an increasing all selected stations. On average, was at rate 0.46/10a. a negative relationship with annual balance caused decrease in balance. Results Pearson’s correlation highly significant between density (correlation coefficient (CC = -0.661...
While the reliable and consistent information on forests dynamic as well communities living in their vicinities are fundamental to sustain socioeconomic environmental benefits, these lacking Wad Al-Bashir Forest (WF) area that located Sennar State of Sudan. Thus, this study assessed land use/land cover (LU/LC) changes cum forests’ dependents needs (FDNs) forestland-related-activities (FRAs) using geospatial techniques alongside key informant interview (KII) structured questionnaire,...
In this study, we investigate the drought pattern in Qinghai Province for period between 1961 and 2013.Utilizing monthly precipitation data of 32 stations adopting Standardized Precipitation Index (SPI), explore possible events over past 53 years.We find a high frequency (on basis 12-month SPI index) 1962, 1966-1967, 1970, 1973, 1986, 1992-1993, 1996 2001-2004.We demonstrate that some areas eastern (including Mangya, Lenghu, Xiaozaohuo, Dachaidan, Ge'ermu, Wudaoliang, Nuomuhong Tuoyuohe) are...
