In this paper, we focus on the sustainability of housing and transport in Lagos, Nigeria. The study’s goal is to give a complete assessment of Lagos’ existing housing condition and to identify urban priority areas that need immediate intervention. The paper also suggests building large public housing developments that do not become exclusive estates for the wealthy, as well as implementing flexible layout plans that prioritise locations above automotive traffic and movement. According to the research, the Lagos metropolis government should address transport concerns immediately and then address other sustainability challenges affecting the city. The paper suggests that geographic information systems and remote sensing technology be used to track rapidly increasing areas and aid in better policy decisions, spatial planning, land management, and infrastructure development. The paper also recommends the development of integrated, pedestrian-friendly mass transit networks, as well as a shift in social and cultural values to emphasise the benefits of non-motorized modes of transportation. Finally, the report emphasises the importance of policies that promote multi-story residential construction, participatory slum upgrading initiatives, mortgage-based homeownership plans, site and service programmes, private sector estate development, and phased urban neighbourhood regeneration. Future work will include analysing the implications of other SDGs relating to sustainable cities.

The paper presents the development of a strategic business and environmental management framework for entering and exiting the Nigerian Oil and Gas (O&G) sector. The entry and exit of O&G companies in the Global South (GS) economy especially Nigeria has been highly impacted by institutional failures, political and economic crisis. Environmental issues and poor strategic management in the O&G have led to inadequately or poorly harnessed resources which affects business, host communities and government interests. Multinational O&G companies entering new markets rely on observed pattern, tactical and strategic data, pattern observed in making informed decision as it relates operating in the business environment. In addition, the need to avert, monitor and report environmental impact of production (through community service engagement) calls for the development of a strategic environmental and business management framework aimed at ensuring successful entry and exit in a sustainable manner. Literature in public domain noted that O&G exploration in the UK continental shelves comes with benefits and challenges to include lack of a global multi-cultural regulation. O&G companies operating in Nigeria have introduced the concept of corporate social responsibility (CSR) in dealing with sustainable development and engaging wider stakeholders’ participation. Literature has also argued the importance of the role of stronger regulatory instruments in attracting foreign direct investments in sustaining the O&G industry. It has also been argued that developing a global strategic management framework for managing O&G supply is key for development of the oil and gas sector. On the environmental front, it has been argued that economic development and public acceptance of the need to transit to a circular economy is crucial in ensuring sustainable development. The paper employs interpretivism research philosophy to analyze global issues relating to O&G business and environmental concerns. It calls for inductive research approach in observation, identification of factual patterns. It uses case study as research strategy to explore and develop a strategic environmental and business management framework for entering and exiting the O&G industry especially in the Nigerian GS. The paper proposed that entry and exit in the oil and gas sector should be anchored on a new framework tool entitled “Company Business to Community Business Entry and Exit Strategy (CBCBEES)”. The framework will permit cooperation and partnership between the oil producing communities and the international O&G companies in their pursuit for sustainable development while protecting the environment. CBCBEES will ensure that investors and host communities can invest in the O&G sector with win-win outcomes. Further work would include collection of primary data as part of the validation process of the developed framework. Future work would also include evaluation of the proposed framework with all stakeholders in the Nigerian O&G sector.

The piezoelectric vibration energy harvesting has higher conversion efficiency and output voltage. The piezoelectric energy harvester has a significant study value for MEMS systems and portable devices. From the research, avoiding the reattachment of vortexes and increasing the pressure difference between the objects could effectively improve the vibration performance. This paper proposes a curved plate with a tail design, expected to have higher vibration frequency and larger amplitude at the galloping phenomenon. The design has been compared with a curved plate design by simulation, showing better performance. Its average lift coefficient increases by 57.42% within wind speed 1-10m/s compared to the curved plate design.

Different countries around the world are facing the production of energy with thermal systems in the current context of the sustainable development. This study analyses the production of thermal energy with district heating system (DHSs) in the Southern of Europe. The methodology used allows for the analysis of the energy systems as well as thermo-energetic conversion and the management of the energy throughout the different phases in a process of analytical hierarchy. This is carried out using a multiphase analysis based on the Spanish context. The results indicate that DHSs save fossil fuels, and reduce greenhouse gas emissions.

Due to increase in demand for electricity usage all around the GCC there has been emphasizing on the usage of alternative sources of energy i.e. using solar, wind and ocean etc. on the other side accurate prediction of power delivery is crucial for estimating the performance of PV and return on investment. In this paper, a case study was presented on different PV technology under the local climatic influence. Analysis of the case study data indicates that the power degradation of all PV modules is observed to be around 2%/yr. and further emphasizing its effect on PV modules and system size it has been observed smaller modules (<120Wp) degrade less than larger modules (>120Wp) and with respect to system size smaller systems degrades faster than larger systems. Hot and dry climate installed PV technologies has witnessed higher degradation than the Hot and humid climate region. In conclusion, it has observed that the degradation rates are much high in GCC than any other parts of the globe and thin film PV modules could be an appropriate choice for hot climatic regions whose degradation rates are considerable.
