Abstract. In this study, the impact of climate change scenarios on the hydrological regimes of five different regions in Germany is investigated. These regions (Northwest Germany, Northeast Germany and East German basins, upper and lower Rhine, pre-Alps) differ with respect to present climate and projected climate change. The physically based SVAT-model SIMULAT is applied to theoretical soil co...
There is great uncertainty over the timing and magnitude of the termination of the African Humid Period (AHP). Spanning from the early to middle Holocene, the AHP was a period of enhanced moisture over most of northern and eastern Africa. However, beginning 8000 years ago the moisture balance shifted due to changing orbital precession and vegetation feedbacks. Some proxy records indicate a rapi...
Geospatial methods were used to study the associations of the environmental thermal-hydrological regime with leprosy prevalence in the Oromia and Amhara regions of Ethiopia. Prediction models were developed that indicated leprosy prevalence was related to: (i) long-term normal climate grid data on temperature and moisture balance (rain/potential evapo-transpiration); (ii) satellite surveillance...
Ecosites are required for stand-level forest management and can be determined within a two-dimensional edatopic grid with soil nutrient regimes (SNRs) moisture (SMRs) as coordinates. A new modeling method is introduced in this study to map high-resolution SNR SMR then design ecosites Nova Scotia, Canada. Using coarse-resolution maps nine topo-hydrologic variables derived from digital elevation ...
Carioca beans are a highly nutritious grain, in terms of the amount of protein, iron and potassium as well as carbohydrates and fiber and as a source of vitamins. The moisture content of recently picked beans is too high for good preservation and storage, resulting in the need for drying before packaging. In this work, the drying of Carioca beans in a laboratory scale spouted bed under intermit...
Soil moisture is a key variable in dryland ecosystems since it determines the occurrence and duration of vegetation water stress and affects the development of weather patterns including rainfall. However, the lack of ground observations of soil moisture and rainfall dynamics in many drylands has long been a major obstacle in understanding ecohydrological processes in these ecosystems. It is al...
The largest demographic in India suffering from the adverse impacts of global climate change are small farmers. India’s rural population is approximately 800 million, with the majority being households dependent on small-scale agriculture. For these smallholders, facing a common rural reality of disempowerment and limited disposable household capital, the agro-ecological results of climate vola...
توسعه صنعتی قرن بیستم منجر به نابودی منابع موجود در محیط زیست از جمله آب و خاک شده است. در این راستا آلودگی خاک به مواد نفتی در کشورهایی که تولید کننده نفت هستند، توجه ویژه ای را می طلبد. درکشور ما به علت استفاده روز افزون ازسوخت های فسیلی و بهره برداری از پالایشگاه ها، از یک سو با افزایش آلودگی های زیست محیطی مخصوصاً آلودگی منابع آب و خاک اطراف این مناطق مواجه هستیم و از سوی دیگر پتانسیل بالفعل...
