Urban planning rules and considering land use regarding faults can change the consequences of natural hazard such as earthquake. Vulnerability risk is increasing in Region 1 because of existence of the north fault, steep slopes and continuous construction of high-rise buildings. It is clear that Region 1’s Master Plan shouldn’t be prepared without considering natural hazard such as ...

Aims: Land-use change due to human activities is one of the important issues in regional and development planning. The aim of this study was to detect land-use changes using Landsat TM, ETM+, IRS and ASTER satellite imagery. Methodology: In this quasi-experimental study, land-use changes in the Haraz watershed over a 23-year period were evaluated. For this study, images of 1992 TM, ETM + 2002, ...

Population growth and the need for economic and social services have accelerated the demands for land and its manipulations over the recent decades. The contribution of policies and interventions of different stakeholders in land change is not adequately addressed in previous studies. This research, therefore, aims to examine the role of key stakeholders, and their policies in land-use change i...

Coastal habitats are situated on the border between land and sea, and ecosystem structure and functioning is influenced by both marine and terrestrial processes. Despite this, most scientific studies and monitoring are conducted either with a terrestrial or an aquatic focus. To address issues concerning climate change impacts in coastal areas, a cross-ecosystem approach is necessary. Since habi...

Different components of global change can have interacting effects on biodiversity and this may influence our ability to detect the specific consequences of climate change through biodiversity indicators. Here, we analyze whether climate change indicators can be affected by land use dynamics that are not directly determined by climate change. To this aim, we analyzed three community-level indic...

Land-use change, including deforestation for agriculture and urbanisation, has coincided with increases in vector-borne diseases worldwide. Landuse change is likely to regulate immature (larvae and pupae) mosquito populations through changes in local temperatures owing to manifold changes to the physical environment. however, we still poorly understand the relationship between land use, water t...

Land use and human occupation within the natural habitats of the Pantanal have facilitated introduction of invasive species of plants and animals, including domestic species. Exotic species threaten regional biodiversity because they modify ecological community structure, alter natural habitats and affect local biodiversity. An international organisation, the International Union for Conservatio...

Estimating the extent of changes in forest and rangelands land cover, leads to a clear understanding of the growth or decline of these natural areas and planning for effective protection of these national assets. The aim of current study was to reveal the trend of land-use changes in the Dizmar protected area of Arasbaran vegetative area, using MSS sensor of Landsat-5 for 1984, ETM+ sensor of L...
