Review ArticleOpen accessIn the abstractThe Status of Pollutants in the Three Gorges Reservoir Area, China and its Ecological Health AssessmentChun-Jiao Lu, Dan Luo, Muhammad Junaid et al.The Three Gorges Reservoir Area (TGRA) stretches along the Yangtze River from Jiangjin District, Chongqing to Yichang, Hubei in China. Since TGRA is the main source of drinking water and fresh fishery in China for millions of people, both researchers and the government have concerns for environmental pollution and ecological security in the TGRA. This review highlighted the status and … …American Journal of Environmental Sciences, Vol. 12, Issue 5 · 28 Sep 2016 · 7,925 accessesView PDFCite
Research ArticleOpen accessIn the abstractTowards Some General Ecological PrinciplesArild WikanDiscrete deterministic age-structured, stage-structured and difference delay equation population models are analysed and compared with respect to stability and nonstationary behaviour. All three models show that species with iteroparous life histories tend to be more stable than species with semelparous life histories which allow us to conclude that this must be a fairly general ecological principle. Considering iteroparity, the precocious … …Journal of Mathematics and Statistics, Vol. 8, Issue 4 · 3 Jan 2013 · 6,929 accessesView PDFCite

Mustapha Mahi, Mme Christine Werner et al.Problem statement: Most of people in rural areas in Morocco don’t have adequate systems of collection, evacuation and transport of black and gray water. They simply defecate in nature. There is a huge demand, which cannot possibly be met by conventional sanitation systems due to the enormous costs of the pipe network, lack of water and serious environmental drawbacks in … …American Journal of Environmental Sciences, Vol. 8, Issue 3 · 7 Apr 2012 · 8,024 accessesView PDFCite
Research ArticleOpen accessIn the abstractEcological Capability Assessment for Multiple-Use in Forest Areas Using GIS- Based Multiple Criteria Decision Making ApproachSasan Babaie-Kafaky, Asadollah Mataji, Naser Ahmadi SaniProblem statement: A valuable Source of plant and animal various species in the west of Iran is Zagros forests that, misuses by foresters and local societies has caused severe degradation. In this study, forest areas ecological assessment was carried out with a (GIS)-based MCDM approach for multiple-use planning in order to reduce degradation and improving sustainability. Approach: All of possible … …American Journal of Environmental Sciences, Vol. 5, Issue 6 · 31 Dec 2009 · 7,887 accessesView PDFCite
Research ArticleOpen accessIn the abstractApplication of a Developed Dispersion Model to Port of BrisbaneSanaz Jahangiri, Natalia Nikolova, Kiril TenekedjievThe emissions from vessels utilising heavy fuel oil include large amounts of nitrogen oxides, sulphur dioxide and particulate matter, presenting significant health risks to people living near ports. To determine the effect of these emissions on human health, complex atmospheric dispersion modelling using CALPUFF assesses ground-level concentrations at receptors surrounding the sources. This paper demonstrates the application of the methodology … …American Journal of Environmental Sciences, Vol. 14, Issue 4 · 12 Oct 2018 · 8,359 accessesView PDFCite
Research ArticleOpen accessIn the abstractMarketing Management of Sustainable Development of Territories in RussiaIrina Skorobogatykh, Daria Malova, Zhanna Musatova, Ekaterina AgalarovaOver recent years a characteristic feature of many countries has been the soaring importance of certain territories both at the national and international levels. A region is considered of primary level when the national economic system evolves.

Research ArticleOpen accessIn the abstractUrbanization Effect on Air Temperature in Iran's Zayanderud River BasinAli Zahraei, Sara Saadati, Saeid Eslamian et al.: Detection of urbanization effect to understand climate change is important. Urbanization effect on air temperature in Zayanderud river basin was evaluated using weather stations network. Map of the temperature trend was generated using full dataset and rural stations to visualize warming trends. A comparative analysis was carried out to estimate urban heat island effect. The result indicated that overall … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 2 · 11 May 2018 · 8,480 accessesView PDFCite
