Mapping spatial patterns of potential biodiversity threats is one of the important steps for effective conservation planning and activities. To determine the spatial patterns of threats in Golestan province, 12 criteria in four main groups including structural (fractal coefficient of perimeter, circularity ratio of area, average slope), compositional aspects of biodiversity (presence of species...
agriculture and its development is the foundation of development in iran as a developing country. so, it can be regarded as the foundation for economical and social development.the capabilities of agriculture sector are limited and its efficiency is trivial because of neglecting agricultural development and keeping its support just as a slogan. the transformation of agriculture to a developed, ...

This study covers a large agricultural and industrial area of Isfahan province, including three types of land use, i.e., agricultural, uncultivated, industrial and urban types. A total of 275 samples from surface soil (0-20 cm) were collected and water soluble fluoride concentrations of them were measured. The spatial structure of water soluble fluoride in the soils was determined by omnidirect...
beneficial management practices (bmps) are important measures for reducing agricultural non-point source (nps) pollution. however, selection of bmps for placement in a watershed requires optimizing available resources to maximize possible water quality benefits. due to its iterative nature, the optimization typically takes a long time to achieve the bmp trade-off results which is not desirable ...
Low-carbon agricultural development in China is a prerequisite for rural revitalization and key to achieving socio-economic green transformation. This paper used data from 30 Chinese provinces 2001 2020, considering both carbon emissions farming livestock, low-carbon total factor productivity (ALTFP) was measured using the RSBM-GML index. Based on this, network characteristics driving mechanism...
Green agriculture is mainstream for the sustainable development of agriculture. Based on Chinese provincial panel data from 2010 to 2019, we adopted slack-based measure (SBM) super-efficiency model, sales force automation (SFA) and global malmquist–luenberger (GML) production index efficiency agricultural green (AGD). Moreover, Moran’s I spatial econometric model were applied analyze factors in...
