Statistical analysis suggested that the volumetric WF of the coal-based products was strongly correlated with both market price and production stage while the variation of WF increased as products were further processed. Optimization result indicated that the maximized economic income of the products under current scenario was 66.23 billion CNY/year in the study area, whereas the overlapping of limited water resources and the insufficiency of downstream production capacity restricted the economic performance by over 20%. In addition, sensitivity analysis was conducted and the results showed that, in order to improve the overall economic income, deployment of more advanced technologies for saving water should be prioritized over that for saving feedstock, while conservation of power was the least preferable.The diffusion of the indicators for monitoring sustainable development goals (SDG) has conceptual and symbolic uses far beyond their instrumental uses. Despite its value in dismantling social and economic inequalities, the goal regarding guaranteed of water and sanitation for all did not specify any indicators for this purpose. This research contributes to the discussions on the best way to monitor inequality in access to water by the SDG. Inequality measures established in other areas of study and specific to the access to water were analyzed as their applicability for this purpose. Our study finds that current United Nations strategy does not allow for robust conclusions and does not respect some economical axioms. Furthermore, we show the potentialities and inconveniences of the most important metrics, but it can be concluded that if the objective is merely to measure inequality and communicate easily, the concentration index is the most appropriate measure. These results may contribute to a more refined discussion of how the SDGs can measures progress towards equality in water access and provides information to guide governments agendas for equality in water access.With possible food crises looming in the near future, urban farming, including small-scale community and home gardens for home consumption, presents a promising option to improve food security in cities. These small-scale farms and gardens often use planter boxes and raised beds filled with lightweight soil or potting mixes. While previous studies on biochar focused on its application on large-scale contiguous farmlands, this study aimed to evaluate the suitability of biochar as a partial soil substitute to produce a durable and lightweight soil-biochar mix for small-scale urban farms. The effects of biochar on the chemical properties of the soil-biochar mix, crop yield and, particularly, crop nutrients and metabolic content were assessed. A germination test using pak choi seeds (Brassica rapa L. cultivar group Pak choi, Green-Petioled Form) showed that the biochar contained phytostimulants. Through a nursery pot experiment over four growth cycles, biochar treatments performed better than pure soil at retaining water-soluble NO3- and K+ ions, but were worse at retaining PO43- ions. Nonetheless, despite its positive effect on soil NO3- retention, biochar application did not improve crop yield significantly when the application rate varied from 0% to 60% (v/v). Untargeted metabolomic analyses showed that biochar application may increase the production of carbohydrates and certain flavonoids and glucosinolates. The results of this study showed that biochar can potentially be used to improve pak choi nutritional values and applied in large quantity to obtain a lightweight soil mix for urban farming.With the demand for restoration and future prediction of climate change effects, subtropical peatlands are expected to be subjected to hydrologic regimes with variable duration and frequency of drained and flooded conditions, but knowledge of their interactive effects on soil biogeochemistry and emission of greenhouse gases including nitrous oxide (N2O) is largely limited.  https://www.selleckchem.com/products/CP-690550.html  The objective of this study was to investigate how the duration and frequency of drainage and flooding events interactively influence soil biogeochemical properties and denitrification and related net N2O production rates following rewetting. Surface soils are susceptible to different hydrologic regimes. Significantly higher pH, extractable organic carbon (ext. OC), ammonium (NH4+-N), denitrification enzyme activity (DEA), but lower nitrate (NO3--N), microbial biomass C and N were observed when the peat soils were under flooded conditions compared to drained conditions. Two-week and four-week drainage or flooding duration did not result in emission pulses following reflooding would decrease with time, attributing to the loss of substrates for denitrification.Whether or not the completely destroyed ecosystem would follow a succession trajectory towards the surrounding forest ecosystem after restoration remains debatable. Here, a comprehensive dataset of thirty-five ecosystem functions were measured on five reclaimed opencast coal mine forest plots (two Robinia pseudoacacia - Pinus tabuliformis mixed forests with different technosol conditions RPT and RPM; one R. pseudoacacia - Ulmus pumila - Ailanthus altissima mixed forest RUA; one Picea meyeri - Picea wilsonii - Hippophae rhamnoides mixed forest PPH; one R. pseudoacacia monoculture forest RM) and one natural forest plot (Populus simonii monoculture forest PM) in Pingshuo opencast coal mine, Shanxi Province, China. These functions were employed to examine the reclamation effects among plots in terms of four management scenarios (i.e., biomass productivity, carbon sequestration, general biodiversity conservation and nutrient accumulation) and to determine the affinities between reclaimed ecosystem and its native ceached a new self-sustaining state after 20-23 years of succession.There is a clear trend in the world to increase the use of sustainable drainage systems. In Poland, it is not as much noticeable, and as a consequence, the conventional stormwater system remains the most common method of stormwater management. As part of the research, an assessment of the issues affecting the implementation of sustainable stormwater management systems in an engineering practices was performed. For that purpose the PESTLE analysis was applied. Its results indicate that legal factors are the key for the development of sustainable drainage systems in Poland. The scale of public support and availability of funding is also not without importance. The possibilities of the implementation growth of sustainable drainage systems should be sought in changes in legal regulations regarding stormwater management, while ensuring at the same time an appropriate level of financing for sustainable solutions. In the second stage of the research, stormwater management models used in Poland were identified. The strengths and weaknesses of these models were presented.
