Adsorption techniques are relatively cheaper particularly when the process is carried out using low-cost materials and biomass. This paper is on the assessment of the potentials of a modified feldspar composite absorbent developed from waste agricultural biomass (Theobroma cocoa pod) and feldspar mineral in the removal of heavy metals from wastewater. \u0000Methodology: The physicochemical analysis were carried out on the wastewater samples before and after treatment with modified feldspar composite using standard methods. Portions of the samples were directly digested and analysed for Pb, Cd, Cr and As, while the second portions were treated with the modified Theobroma cocoa pod-Felspar (TCPF) adsorbent under optimum conditions before analysing for the heavy metals. The desorption (cleaning) of the TCPF adsorbent after the adsorption of the heavy metals (Pb, Cd, As and Cr) from the wastewater was carried out with 0.1 M HCl. \u0000Findings: The AAS analysis revealed that, the concentrations of the heavy metals in the wastewater before treatment with TCPF were higher and followed Pb>Cr>Cd>As trend and were above WHO and NESREA standards. The values for the samples treated with TCPF were lower and followed Cr>As>Pb>Cd trend and were within the standards. The differences between the values for the individual metals in the wastewater before and after treatment with the TCPF adsorbent were significant at p< 0.05. The adsorption efficiency of the TCPF was high for Pb (98.92%), Cd (96.88%) and Cr (97.18). Similarly, the TCPF showed high desorption efficiency with 76.8% for Pb, 90.6% for Cd, 94.4% for As and 80.3% for Cr. \u0000Unique contribution to theory policy and practice: The modified composite (TCPF) has shown some significant potentials for use in the removal of the selected heavy metals from wastewater and industrial effluent.","PeriodicalId":47090,"journal":{"name":"Journal of Environment & Development","volume":"28 1","pages":""},"PeriodicalIF":3.2,"publicationDate":"2023-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87145998","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Empirical Research on the Interaction Between Poverty Alleviation and Carbon Emissions","authors":"Haoyan Li, Huixing Jiang, Zhongqi Wu","doi":"10.1177/10704965231190128","DOIUrl":"https://doi.org/10.1177/10704965231190128","url":null,"abstract":"Consolidating the results of poverty alleviation and achieving carbon neutrality are serious challenges for global sustainable development, and it is essential to explore the relationship between these goals, and then offer scientific responses. Based on the panel data of 30 provinces in China from 2010 to 2019, this paper conducted the 2SLS model by compromising the merits of the Regression Discontinuity principle with the STIRPAT model to study the interaction between poverty alleviation and carbon reduction. The study found that: (1) the implementation of poverty alleviation aggravates the problem of carbon emissions, and the main mechanism is that poverty alleviation promotes consumption and production by increasing the wealth of farmers, thereby increasing carbon emissions. (2) Carbon reduction weakens the achievement of poverty alleviation significantly, but the mitigation effect presents an “inverted U”-shaped curve, which first increases and then wanes. (3) Farmers' income and the development of rural transportation play a role in acting on the negative effects of carbon reduction. By integrating poverty theory and energy management, this article reveals the complex relationship between two important policies in China and offers relevant policy recommendations, which will not only promote the advancement of rural revitalization but also promote global sustainable development.","PeriodicalId":47090,"journal":{"name":"Journal of Environment & Development","volume":"32 1","pages":"274 - 301"},"PeriodicalIF":3.2,"publicationDate":"2023-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49055498","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These interventions are so far mostly being studied and applied in high-income countries. Here, we examine their application to achieve carbon emissions reduction in low- and middle-income countries. This involves synthesizing evidence from meta-analyses and systematic reviews from developed countries and deriving general insights for developing countries. We also review evidence from primary studies in developing countries, organizing insights by major world regions. We discuss context dependence of findings, as well to what extent behavioral interventions are complementary to, and create synergies with, other policy instruments. We hope that the present overview serves as starting point to expand the currently small evidence base on climate-relevant behavioral interventions in developing countries.

This article investigates how World Wildlife Fund (WWF) helps implement the Aquaculture Stewardship Council (ASC) ecolabel standard in Indonesia. As the world’s second-largest aquaculture fish-producing country, many Indonesian seafood products are rejected in the international market due to quality problems. This makes Indonesia an ideal country for implementing sustainable aquaculture practices. Using transition theory as a framework, we find that WWF has played a key role in three areas: (1) harmonisation of national regulations with ASC principles, (2) establishment of a campaign program to advocate for the public on sustainable seafood consumption behaviour, and (3) creating a special agency to assist to fishery industry players in obtaining ASC certificates. Our finding sheds lights on the importance of strong collaboration between business actors, states, and non-governmental organisations (NGOs) to implement global voluntary standards.","PeriodicalId":47090,"journal":{"name":"Journal of Environment & Development","volume":"32 1","pages":"165 - 191"},"PeriodicalIF":3.2,"publicationDate":"2023-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44429190","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
