The paradox of assessing greenhouse gases from soils for nature-based solutions

چکیده

Abstract. Quantifying the role of soils in nature-based solutions requires accurate estimates soil greenhouse gas (GHG) fluxes. Technological advances allow us to measure multiple GHGs simultaneously, and now it is possible provide complete GHG budgets from (i.e., CO2, CH4, N2O fluxes). We propose that there a conflict between convenience simultaneously measuring fluxes at fixed time intervals (e.g., once or twice per month) intrinsic temporal variability patterns different Information derived – commonly done during manual field campaigns had limitations reproducing statistical properties, dependence, annual budgets, associated uncertainty when compared with information continuous measurements automated hourly measurements) for all present novel approach univariate Latin hypercube sampling) can be applied insights optimize monitoring efforts across time. suggest should not measured few (mainly are limited month), but an optimized sampling used reduce bias uncertainty. These results have implications assessing consequently solutions.

Evaluation of emission of greenhouse gases from soils amended with sewage sludge.

Increase in concentrations of various greenhouse gases and their possible contributions to the global warming are becoming a serious concern. Anthropogenic activities such as cultivation of flooded rice and application of waste materials, such as sewage sludge which are rich in C and N, as soil amendments could contribute to the increase in emission of greenhouse gases such as methane (CH(4)) a...

Greenhouse Gases

Examination of research into pole alternatives indicates that, without exception, studies have found that total energy requirements associated with wood materials are considerably lower than those of commonly substituted materials. The substitution of high-energy-intensive materials for low-energy-using wood materials would contribute substantially to an overall increase in carbon
