Abstract Freshwater is essential for everyday activities including drinking, irrigation, farming and many industrial processes. However, freshwater is less than 1% of the total water resources in the planet and, therefore, it is considered a very valuable commodity. Limited resources and growing needs for freshwater triggered global exploration for alternatives to produce enough freshwater for human needs. Today’s most widely used methods to produce freshwater is desalination. However, critical appraisal of the desalination procedures raised the alarm about sustainability of desalination and indicated that significant research is needed to develop alternative green resources of freshwater. Countries in the Gulf area such as Oman and UAE experience hot and humid climates and use air-conditioning units to achieve acceptable comfort levels and create a healthier indoor environment. The cooling process release a large amount of condensate water through cooling coils. This amount of water is usually considered as a problem rather than opportunity and, thus, is wasted into municipal sewerage systems via a system of drainage pipes. This alternative source can be utilized in various drainage, irrigation, and cooling applications to reduce the use of considerable amount of municipal potable water. This source not only takes part in controlling the water scarcity, but also in saving energy and to reducing the carbon footprint. This paper focus on highlighting the opportunities for Oman and UAE to utilize the condensate water from air-conditioning process, as a viable alternative source of green fresh water. It provides a comparison of the potentials of both countries to collect condensate water, based on meteorological data, location and climate. It was concluded that both countries have great potentials and opportunities to utilize this wasted resource.

Abstract This study assessed genders’ institutional level of arrangement in REDD + pilot sites, Cross River State, Nigeria. Data were collected through literature and policy document review and Focus Group Discussion (FGD). The total number of 270 documents with three, Level 1 : Non-substantive inclusion, Level 2 : Superficial inclusion and Level 3 : Integrated inclusion. The gender were classified as Men and Women for the search engine. The results showed that only 95 of the 270 REDD + related documents mentioned gender (representing 51% of the total documents). Nearly half of the texts that include the crucial phrases were categorized at Level 1, which means that gender concerns were not material. Regardless of how it is seen, the meager inclusion of gender mainstreaming discussion can only be found in Level 3. This 7% translated to only 12 out of the 270 documents which truly and fully understood the gender mainstreaming ideas. The study concluded that communities’ policy interventions such as REDD + still exhibit non-compliance of gender mainstreaming and institutional level of arrangement , therefore, this study recommend that “ sincerity ” of gender mainstreaming from the government and other stakeholders is a panacea for the success of any climate change adaptation programme such as REDD + .

Abstract Gender and mobility are strongly related and address challenges of safety and accessibility for women. Studies worldwide highlight the need to create more gender-responsive transport systems that maximize women’s mobility, civic participation, and safety. Gender inequality in urban transport is evident in Indian cities in terms of women’s longer walking trip lengths, longer time spent in commute and hence time poverty, impoverished health, and compromised personal safety. Even the public transport systems, often perceived as more gender-equal, overlook women’s needs and mobility concerns such as affordability and scheduling. This article presents transportation challenges faced by women (recorded through primary surveys and focus-group discussions) and further investigates how low-carbon urban transport, as perceived under the Paris Agreement and Sustainable Development Goals (SDGs), can be delivered with gender-equitable outcomes. For a more holistic perspective, the assessment is grounded in two Indian cities, Surat (4.5 million population), a fast-growing industrial metropolis, and Udaipur (0.5 million population), a small but important tourist destination in the nation.

Abstract This study investigates the impact of planned tram lines on walkability and accessibility in Sakarya, utilizing Geographic Information Systems (GIS) for spatial analysis. The research evaluates the catchment areas of proposed tram stops, assessing their suitability and coverage, and examines how these areas integrate with existing public transport routes. By calculating time-oriented catchments for 5, 8, and 10-minute walking distances, the study identifies service gaps and redundancies in the public transport network. The findings reveal that the new tram lines will enhance accessibility by extending coverage to high-density areas and potentially reducing the demand on existing bus services. The analysis also highlights the overlap between bus transit lines and tram stops, suggesting optimizations to improve network efficiency. The results offer valuable insights for urban planners, aiming to optimize Sakarya’s public transport system to be more inclusive and sustainable. This study contributes to urban mobility planning by providing a detailed understanding of how new tram lines can improve connectivity and support sustainable urban development.

Abstract This study investigates the impact of sustainable sourcing practices on firm performance and stakeholder satisfaction across various industries. Using a quantitative approach, data were collected from 500 firms through a structured survey questionnaire. The findings reveal that sustainable sourcing practices lead to a significant positive impact on firm performance, with an average 15% increase in profitability and 20% improvement in stakeholder satisfaction scores. The regression analysis shows a strong correlation ( r = 0.45, p < 0.001) between sustainable sourcing and enhanced firm outcomes. The study identifies firm size, industry type, and sustainability awareness as critical factors influencing the adoption of sustainable practices. Recommendations include integrating sustainability into procurement processes to enhance long-term performance. Future research should explore the longitudinal effects of these practices across different market conditions.

Abstract The ability to solve real-world problems for a sustainable future has become a worldwide consensus, and interdisciplinary competencies and project-based learning (PBL) have become the focus of curriculum reform in China. This study investigates the effectiveness of interdisciplinary PBL fieldwork in geography education for sustainable development, focusing on the perceptions of students from a junior high school in Chongming, Shanghai, of the interdisciplinary effectiveness of PBL fieldwork. Over a one-month pilot program, the results suggest that the new fieldwork approach did not achieve the expected benefits. The significant gains of students can be grouped into four perspectives, namely, understanding of nature and classroom knowledge; problem-solving skills and environmental action; scientific spirit, environmental awareness, and interest in geography; and understanding of local needs and sustainable development issues, which increased their interest in learning. The students generally accepted the ability to collect information and data and the thinking ability of circular development. The influencing factors of activity effectiveness include the time and difficulty of the activity, cognitive and knowledge levels, learning habits of students, student participation, and teaching experience of teachers. The study offers valuable insights for improving fieldwork in other regions and for future research.
