Accurate estimation of soil organic carbon (SOC) is critical for carbon accounting in high-altitude ecosystems, where variability in soil properties challenges the use of standardized conversion factors. This study assesses the validity of the Van Bemmelen conversion factor (1.724) for estimating SOC from soil organic matter (SOM) across contrasting Andean ecosystems within the upper Pastaza River watershed in Ecuador, with a primary focus on paramo. A total of 109 soil samples were collected at 30 cm depth using ...

The recurrence of droughts increased in the past decades and is foreseen to intensify affecting larger areas than today. As agriculture is among the economic sectors most vulnerable to climate change, with drought representing a key challenge for crop productions, this study assesses the probability of yield loss for major Romanian crops such as, winter wheat, maize, sunflower, grape, in response to varying intensities of drought. To achieve this, a probabilistic modeling framework was constructed, integrating the...

The study is based on an assessment of the level of land disturbance by full-scale military operations and the emergence of land use deficits in certain territories. It has been determined that military operations cause disturbance of the earth's surface in the form of mechanical, physical and chemical changes in the soil, the negative consequences of which can be felt for decades. Territories that have been subjected to military operations become dangerous for the population for a long time and unattractive for i...

The health of soil, groundwater, air and the entire environment of inhabited areas depends largely on the intensity of agriculture and its systems. In order to achieve the desired quantity, quality and economic profitability, it is necessary to apply large amounts of unnatural, often chemical substances in the production process in order to achieve the desired and profitable harvests. These are mainly industrial fertilizers, which, when used for a long time, can contaminate all components of the environment. Altho...
