The root cause of agricultural land degradation and decreasing productivity – as seen in terms of loss of soil health -is our low soil-carbon farming paradigm of intensive tillage which disrupts and debilitates many important soil-mediated ecosystem functions. For the most part agricultural soils in tillage-based farming without organic surface residue protection are becoming de-structured and ...

Knowledge of oviposition sites selected by wetland mosquitoes could improve mosquito control and guide wetland rehabilitation practices to avoid creating or exacerbating a mosquito problem. Two studies that enumerated Aedes vigilax eggshells found in salt marsh soil on the western portion of Kooragang Island in New South Wales, Australia, allowed an evaluation of oviposition sites. In one study...

The concept of an integrated multifunctional river management is gaining importance. For major rivers, restoring the contact between rivers and alluvial plains is an important goal, as riparian areas have a specific role for several riverine processes. However, former and current human activities are an obstruction or a limitation for river restoration. We studied the influence of former dredgi...

We conducted a study for enhanced biological rehabilitation of chromium-contaminated soils using a chromium-reducing and nitrogen-fixing bacterial species (Bacillus megaterium-ASNF3). The bacterial species was isolated from a chromium-rich land area, characterized, and employed under optimum conditions for the treatment of artificially prepared chromium-rich soil. The bacterium reduced Cr(VI) u...

the situation of people with disabilities in the developing countries should be a matter of great concern. there are today close to 250 million severely and moderately disabled persons in these countries; the annual increase is 10 million. most of them are poor, dependent neglected, excluded from education, training and jobs; they die early and have no power while alive. between 15 and 20% of a...

due to the notable role of different land uses in carbon sequestration and emission, four treatments including rangeland as control, haloxylon plantation area, olea plantation (olive garden), and residential lands, were selected to study the effects of land use change on soil carbon sequestration and emissions in eivanakei rangelands, semnan province. carbon stocks in vegetation and soil of eac...
