The industrialization of the agricultural sector has increased the chemical burden on natural ecosystems. Pesticides are agrochemicals used in agricultural lands, public health programs, and urban green areas in order to protect plants and humans from various diseases. However, due to their known ability to cause a large number of negative health and environmental effects, their side effects ca...

Surface water quality in the Lower Mississippi River Basin (LMRB) and the adjacent Gulf of Mexico has degraded over the past several decades primarily due to deforestation to agricultural lands and the loss of wetlands. This study investigated the benefits of reforestation upon nitrate–nitrogen (NO 3 N) and orthophosphate (PO 4 ) load reductions in the Lower Yazoo River Watershed (LYRW) within ...

Algae are very large and diverse group of simple, typically autotrophic organisms that can carried out photosynthesis and have ability to capture energy from sunlight. Algae play an important role in sustainable and organic agriculture where it is used as biofertilizer and soil stabilizers. Algae, particularly the seaweeds, are used as fertilizers, resulting in less nitrogen and phosphorous run...

land use change of forest ecosystems in northern iran changes the soil quality of paresar (gilan province) and gorgan (gorgan province) regions. in order to study changes in some biological soil quality indices due to land use change from forest to cultivated lands, composite soil samples from two depths (0-20 and 20-40 cm) were taken from paresar and gorgan regions and urease, alkaline and aci...

Large tracts of tropical rainforests are being converted into intensive agricultural lands. Such anthropogenic disturbances are known to reduce species turnover across horizontal distances. But it is not known if they can also reduce species turnover across vertical distances (elevation), which have steeper climatic differences. We measured turnover in birds across horizontal and vertical sampl...

BACKGROUND Various species of forest trees are commonly used for ornamental purposes and are therefore frequently found in non-forest ecosystems. These trees constitute a significant component of the trees outside forests (TOF). Although increasingly recognized as prominent feature of agricultural lands and built-up areas, not much is known, however, about TOF since they are generally absent fr...

Introduction: Awareness of soil quality in agricultural lands and natural resources is essential to achieve maximum production and environmental sustainability. Although soil quality is not directly assessed, soil quality indicators are widely used today, including the physical indicators which are of great importance in measuring the soil quality, as they directly influence the plant growth an...

Background: Despite that has passed decades from sustainability issues, but we are still seeing that farmers misuse the sources of production, and agricultural policies do not fit with the environmental capacity of regions and being brilliant of the term self-sufficiency in among agricultural development policies. It seems all the levers so far have been used to achieve sustainability so should...
