The change of land use/land cover has been known as an imperative force in environmental alteration, especially in arid and semi-arid areas. This research was mainly aimed to assess the validity of two major types of land change modeling techniques via a three dimensional approach in Birjand urban watershed located in an arid climatic region of Iran. Thus, a Markovian approach based on two suit...

Abstract Eutrophication is a common problem for the dams situated within an urban or agricultural catchment with high source of untreated plant nutrients. This can negatively affect hydro ecosystem, recreational and other uses water. On hand, such eutrophic could also be rich nutrients use. Thinking irrigation as alternative means reservoir water management, suitability was investigated Roodepl...

The variety of interactions between human cultures and herpetofauna is the subject matter of Ethnoherpetology, a subdivision of Ethnozoology. In the semi-arid region of Brazil, many reptiles interact with human communities because of their utility or because of the risks they represent. These interactions have obvious implications for the conservation of reptiles from this region. In this conte...

Accurate evapotranspiration (ET) estimation is very crucial for water resource management, particularly for the arid and semi-arid region. The remote sensing-based Priestley-Taylor method (RS-PT method) can estimate ET at regional scale, using the feature space of remotely sensed land surface temperature (LST) and vegetation index (VI). This study evaluates the RS-PT feature space method over a...

Lithologic mapping in the hostile and inaccessible mountainous region like the Himalaya and Tibet has frequently been a great challenge for geologists. The remote sensing techniques should be a potential player in lithologic mapping and structural analysis in these mountainous regions. With the successful development of minrealogic indices, e.g., Quartz Index (QI), Carbonate Index (CI), Mafic I...

Brazil, together with all the member countries of the United Nations, is in a process of adoption of a group of Sustainable Development Goals, including targets and indicators. This article considers the implications of these goals and their proposed targets, for the Semi-Arid region of Brazil. This region has recurring droughts which may worsen with climate change, further weakening the situat...

The Green and Blue Infrastructure (GBI) is a new approach for dealing with biodiversity conservation based on maintaining the ecological networks by ensuring survival of animal plant species. GBI considered public policy to avoid loss preserving landscape connectivity protecting natural habitats from fragmentation. Countries including United States, Canada, Kingdom, Italy, Portugal, Japan, Chin...
