Abstract
This paper presents a report as part of a comprehensive study on the utilization of some forms of solid waste (SW) to make charcoal briquettes (CB) as an alternative fuel source in communities that are reliant upon traditional charcoal (TC) and wood as the primary cooking fuels. The study coincides with the Tanzanian government’s efforts to diminish reliance on wood and charcoal as a primary fuel source, particularly for large-scale consumers. Nevertheless, the government restriction on TC usage comes with little or no presentation of alternative sources that are both eco-friendly and economically sustainable. Introducing the mechanism that meets both environmental and economic criteria, the study employs a cross-sectional approach to collect the required data and uses experimental methods to evaluate the performance of the produced CB. Such tests focused on cooking duration, burning rate (BR), specific fuel consumption (SFC), and the general efficiency expressed by the percentage of heat utilized (PHU). In most cases, CB performs by far or less well than TC. Such results make the study important as it develops clean cooking technologies to solve the existing fuel crisis and improve health and environmental conditions from SW pollution while reducing deforestation, subsequent desertification, and climate change for sustainable environmental conservation.

Abstract
This article explores the integration of Eco Cities and Smart Regions to create sustainable and innovative urban environments. Eco Cities focus on environmental sustainability through renewable energy, waste management, and green infrastructure, aiming to reduce ecological footprints and promote healthy lifestyles. Smart Regions, on the other hand, utilize advanced technologies such as the Internet of Things (IoT), artificial intelligence (AI), and big data analytics to enhance public service efficiency, optimize resource use, and foster economic development. The study highlights how combining these two approaches can lead to significant benefits, including improved operational efficiency, better quality of life, environmental resilience, and active citizen participation. Case studies of cities like Copenhagen and Singapore demonstrate successful integration, showcasing achievements in sustainability and technological innovation. The article also identifies the main challenges in this integration, including technical compatibility, cybersecurity risks, high initial investments, digital inequality, and the need for robust governance frameworks. Overcoming these challenges requires collaborative efforts among governments, private sectors, and civil society, as well as innovative financing strategies and capacity-building programs. Future considerations emphasize the need for a holistic approach to urban planning that incorporates emerging technologies, flexible and adaptive strategies, and inclusive citizen engagement. By addressing these factors, cities and regions can become more resilient, sustainable, and inclusive, meeting the needs of both current and future generations. This integrated approach promises to transform urban environments into hubs of sustainability and innovation, driving long-term positive outcomes for society and the environment.

Abstract
India as a country has its identity deeply rooted in its rural culture. Whether we talk about agriculture, tradition, food, art, or music, the rural society of India has always proven itself a representation towards the national front. The Dayalbagh society in Agra city of Uttar Pradesh (India) is engaged to strengthen the nation’s roots through education, technology, sustainability, management, innovation, research, and most importantly, selfless service. The major potential for economic growth in India lies in the development of its rural areas. This article is an attempt to spot the outlook of a society that has its inception for the past 100 years and is continuously making efforts to glorify the message of sustainable development, environmental protection, and rural development through its effective plans in designing an eco-village-based society. Based on the narrative description approach, this article highlights the efforts and strategies employed by the Dayalbagh society to promote sustainable development, environmental protection, and rural development. The focus is on how society integrates education, technology, sustainability, management, innovation, research, and selfless service to achieve these goals.

Abstract
The exacerbation of climate change impacts within metropolitan areas is a well-documented phenomenon, often leading to severe consequences that pose significant risks to human populations. The impact of urban vegetation and planting design on these factors can be observed. However, it is worth mentioning that while there is an extensive body of literature on the consequences of climate change, there is a relatively small number of studies specifically focused on examining the role of vegetation as a mitigating factor in urban environments. This review paper aims to critically examine existing studies pertaining to the role of urban vegetation in mitigating the detrimental effects of the urban environment. The objective is to offer practical recommendations that can be implemented by city planners. By conducting a comprehensive examination of the literature available in Scopus, Web of Science, and Google Scholar, employing specific keywords pertaining to urban vegetation and climate change, we have identified five prominent concerns pertaining to the urban environment. These concerns encompass particulate matter, gaseous pollution, noise pollution, water runoff, and the urban heat island effect. The present analysis highlights that the impact of urban vegetation on the negative consequences of climate change cannot be unequivocally classified as either positive or negative. This is due to the fact that the influence of urban greenery is intricately connected to factors such as the arrangement, makeup, and dispersion of vegetation, as well as the specific management criteria employed. Hence, this research has the potential to enhance comprehension of the multifaceted nature of urban green spaces and establish a solid groundwork for subsequent investigations.
