It is also involved in the amendment of soil by altering the nutrients, pH and other factors. Through intensive literature review, this paper was aimed to better understand the selection of feedstock processes, preparation, and characterization of biochar. Wide variety of feedstock used for the biochar production based on the cost effectiveness, ease availability and they are ecofriendly to the environment. Among the thermochemical processes, pyrolysis is the promising techniques followed for the production of BC. The stabilization efficacy was mainly determined by cation exchange capacity, pH, and ash content of the biochar. The physicochemical characteristic of the biochar is analyzed using various methods such as SEM, FTIR, TGA and BET analysis. The surface area plays a major role in the metal sorption. The quality characteristics of biochar as a soil amendment varied greatly with the feedstock materials and the pyrolysis conditions. Biochar plays a great role in increasing the pH which helps the acidic soil region and its high-water retention capacity enhance the moisture level in the soil which enhances the microbial communities and its activity. Biochar becomes stabilized in the soil by interacting with soil particles. The inherent characteristics of the biochar as dictated by feedstock and pyrolysis conditions, interact with climatic conditions such as precipitation and temperature to influence how long biochar carbon remains stored in the soil. Due to its carbon sequestration in the soil, it helps in increasing the fertility of the soil and also enhances the crop yield.","PeriodicalId":14445,"journal":{"name":"International Journal on Environmental Sciences","volume":"36 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74087603","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thus, a diagnosis that has the potential to cure that critical stage of water with no harmful impact on the other elements of nature is an utmost requirement now a days. Tremendous development in the field of research has suggested a number of treatment methods to get over water pollution. Constructed wetland (CW) an engineered unit that follows bio-geochemical approaches to heal the polluted stage of water with a significant pollutant removal efficiency, has stood first in the field of sustainable water treatment and technology. Not only water treatment through an eco-friendly manner but also creating an ecosystem with in that working area with aesthetic and economical production are the major reasons behind the popularity of this system. Selection of vegetation, substrate and construction of that system at a proper location are the limitation of constructed wetland. In this system sedimentation, filtration and adsorption through substrate, neutralization, and precipitations, phyto-accumulation of plant species and microbial remediation by microorganisms present in the rhizospheres of plants etc. are the processes that supports the treatment activity. This paper discusses various types of constructed wetlands and their mechanism and performance intended for municipal wastewater treatment. Besides it the paper covers the discussion regarding reusability of the treated water. This paper will help promote the wastewater treatment using CWs and further help to design and develop innovative hybrid technologies for sustainable wastewater treatment.","PeriodicalId":14445,"journal":{"name":"International Journal on Environmental Sciences","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79914269","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study is mainly focused on climate change impacts on wetland ecosystems over Harike and Keshopur wetland in Punjab region, India. Harike wetland is one of largest wetland in northern part of India, which is designated as Ramsar site. The Landsat imageries and climate parameters (includes land surface temperature and rainfall) have been used to extract spatial and temporal information over wetlands during period from 2009 to 2020. Landsat data have been analysed in two phases: Pre-monsoon and Post-Monsoon. Wetland area has been classified into five different classes: agriculture, water, built-up, aquatic vegetation1, and aquatic vegetation2. These analyses showed that wetland area has been reduced over a period of ten years and much area has been converted in agricultural land and built-up. The intense anthropogenic activities have resulted more changes in the wetland over both regions. The present study specifies that wetland ecosystem monitoring is essential for policy makers for sustainable management and also concluded that the significant reduction of highly biodiversity wetland area is required to conserve.","PeriodicalId":14445,"journal":{"name":"International Journal on Environmental Sciences","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81435236","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
