    Abstract: Urban areas are constantly developing and rapidly, especially in recent times. According to the United Nations, in 1950 the global urban population accounted for only 29% of the world's population; this figure was 50% in 2009 and will be 60% in 2030 with about 5 billion people. In Vietnam, urban population is projected to account for 38% of the country's population by 2015, 45% of the country's population in 2020 and 50% of the national population by 2025 with about 25 million. In the process of urbanization with growth and development, cities often face significant challenges. These are: 1) Unbalanced development, over-focus on large cities makes the development gap between urban and rural areas more and more increasing; 2) Unsustainable development, rapid technical and social infrastructure systems degrading rapidly, especially housing and environmental sanitation; 3) The administrative management capacity of urban governments must often chase the rapid growth of urban areas; 4) Poverty, crime and unemployment often occur in rapidly growing cities but lack solid economic and technical bases. In order to have an identity of sustainable urban development, development cannot be separated from preserving stability in which urban management is always a very important task.

    Abstract: Landfill is a popular method of waste disposal in many countries due to its relatively low of costs of operation. The offensive aspect of the method is improper removal or disposal of the waste, which has resulted in avoidable sicknesses, diseases and preventable deaths. Carbon dioxide and methane are the two main gases emitted from landfill sites; municipal solid waste issue accounts for almost 5% of total greenhouse gas emissions and methane from landfills accounts for 12% of the total quantity of global methane emissions. Landfills can be put to sustainable use by employing it to produce energy from waste whenever is feasible and it has the capacity to generate revenue. Furthermore, many advanced waste treatment technologies have been developed which received commendable attention in developed countries and are evolving in developing countries. Landfill gas-to-energy is viable economically and for control of methane emissions and effective management of time, costs and quality with minimum risks to humans and the environment.

    Abstract: Today, it becomes indispensable for businesses to have socially responsible behaviors and environmental approaches. Businesses should prioritize corporate social responsibility (CSR), environmental innovation and environmental performance in order to avoid global environmental problems that may emerge as a result of irresponsible behaviours and lack of environmental protection. This study aims to propose a theoretical model for the relationship between CSR, environmental innovation and environmental performance. For this purpose, the relations between the variables were examined in the light of research and studies in the literature and a theoretical model was proposed based on the information obtained.

    Abstract: ESG implementation is one of factors in establishing a sustainable business. Businesses in Indonesia also need to implement ESG to achieve net zero emissions by 2026. This study describes the implementation of ESG (Environmental, Social, and Governance) to strengthen PT. Migas–North Field. This qualitative study uses an interview technique with 5 employees of PT Migas. This study focuses on the implementation of 30 indicators from ESG Reporting Guide 2.0. The findings show, in the environmental aspect, the indicators that have been practiced in the company consist of GhG emission, emission intensity, energy usage, energy intensity, energy mix, water usage, and environmental operation. While the indicator has not been practiced is climate oversight/board, climate oversight management, and climate risk mitigation. In the social aspect, the indicators that have been implemented by the company are the CEO Pay Ratio, Gender Pay Ratio, Temporary Worker Ratio, Non-discrimination, Injury Rate, Child & Forced Labor, Global Health & Safety, and Human Rights. While the indicators of Gender Diversity and Employee Turnover have not been implemented. In the governance aspect, the indicators that have been implemented by the company are Board Independence, Collective Bargaining, Supplier Code of Conduct, Ethic & Anti-Corruption, and Data Privacy. While the indicators that have not been implemented are Board Diversity, ESG Reporting, Disclosure Practice, Incentivized Pay, and External Assurance. All of indicators above actually have an urgency to be implemented in order to create business sustainability.

    Abstract: Tomato (Lycopersicon esculentum Mill) is one of the most important and has the highest acreage of any vegetable crop in the world. Such quantitative analysis is based on the assessment of data from sequential collections of plant traits linked to environmental conditions, as well as yield potential under optimal growth conditions. The objective in this study was to evaluate the performance of tomato crop under furrow, basin and hosepipe irrigation techniques in Kabos, Serere District of Eastern Uganda. The materials and methods used in this study included tools like water pump (model DCX2-50D), Tomato variety Rionex, weighting scale, CROPWAT 8.0 software, CANOPEO software among others. Generally, quantitative techniques through several experiment designs were used. Daily and monthly weather variables, in-situ primary datasets of plant height, canopy cover percentages and fruit characteristics, and weight of harvested tomatoes were measured at three growth stages and analyzed using RCBD experiment with six treatments and four replications. Findings showed that overhead treatments had lowest rate of rotten yield compared to basin and furrow but had highest rate of discolored fruits attributed to sunshine and impact of water pressure during irrigation. Rotting of yield was highest in basin treatments. The rotting was attributed to water logging, poor drainage that accelerated fungal infection in the tomatoes. Furrow treatments had better drainage which reduced quantity of nonmarketable yield. There was no significant difference on the weight of tomatoes below 65g. This meant that fruit weight was independent of irrigation method. Treatments under hosepipe irrigation-overhead. Conclusively, water management practices have big impact on the crop yield giving a relationship that yield is directly proportional to water management practices, which however, should be followed by detailed soil and water analysis through such studies. The Safe-Water-for Food (SWFF) target can be reached and eventually reduce on the global hunger syndrome.

    Abstract: Global population growth and climate change are adding pressure on conventional water sources to meet the rising demand. Reliance on unconventional water sources utilizing desalination technologies is increasing to ensure water security. A major economic and environmental challenge in the sustainable adoption of desalination is the hypersaline concentrate that is generated as a byproduct. Brine quantification estimation process and disposal strategies along with the associated costs are provided. Brine re-use for biomass production offers a promising solution to help mitigate the environmental and economic challenges related to brine disposal. Soil salinization is a key issue with the land application of brine impacting its sustainability and applicability in the long run. The paper proposes a methodology for multi-stage biomass production using desalination brine. Added advantage of the proposed methodology is the potential to manage soil salinization, adopt sustainable agricultural practices such as crop rotation and enhancing biodiversity through inclusion of marshlands and wetlands as part of the brine disposal strategy. The paper also proposes an experimental setup for lab scale experimentation and identifies research priorities and provides recommendations for further evaluation.

    Assessment of Integrated Waste Management Systems in Kandahar City, Afghanistan
    European Open Science Publishing ; 2019

    Abstract: Life Cycle Assessment (LCA) of current MSWMS for Kandahar City and two developed integrated waste management systems (IWMSs) were carried out. In addition, field survey was performed to find out the composition of MSW in Kandahar City as this was the base line data for the LCA’s. Field survey at the MSW disposal site of Kandahar City revealed that physical composition of food waste was low (26.89%) and inert (soil, sand, brick, etc.) was high (39.72%) because of constructional activities, and street and canal cleaning. LCA of current MSWMS was carried out with inclusion of fuel energy production, transport, burning used engine oil obtained from vehicles maintenance, and MSW degradation in its system boundary. The result showed that environmental impact potential for global warming, ozone depletion, terrestrial acidification, freshwater eutrophication, human toxicity, photo oxidant formation and particulate matter formation were 1504.6 kg CO2 equivalent, 13 g CFC-11 equivalent, 1.11 kg SO2 equivalent, 645 mg P equivalent, 28.77 kg 1,4-DB equivalent, 0.46 kg C2H4 equivalent plus 2.11 kg NMVOC, and 0.55 kg PM10 equivalent, respectively, per functional unit (FU). MSW degradation and transport were the processes mostly contributing to potential environmental impact. In scenario 1, recycling (RC) avoided energy and raw materials consumption for new production. It could reduce 10.6% (159.3 kg CO2 equivalent) global warming potential (GWP) compared to base scenario. In scenario 2, in spite of recycling, anaerobic digestion was included to recover energy and compost. Scenario 2 showed reduction of 32.6% (490 kg CO2 equivalent) GWP compared to base scenario. Hence, scenario 2 was a better IWMS in term of environmental sustainability to be considered by decision makers in Kandahar City.
