Effective waste management is a major challenge for small island developing states (SIDS) like Maldives due to limited land availability. Maldives exemplifies these issues as one of the most geographically dispersed countries, with a population unevenly distributed across numerous islands varying greatly in size and population density. This study provides an in-depth analysis of the unique waste management practices across different regions of Maldives in relation to its natural and socioeconomic context. Data shows Maldives has one of the highest population density and per capita waste generation among SIDS, despite its small land area and medium GDP per capita. Large disparities exist between the densely populated capital Male’ with only 5.8 km2 area generating 63% of waste and the ~194 scattered outer islands with ad hoc waste management practices. Given Male’s dense population and high calorific waste, incineration could generate up to ~30 GW/a energy and even increase Maldives’ renewable energy supply by 200%. In contrast, decentralized anaerobic digestion presents an optimal solution for outer islands to reduce waste volume while providing over 40%–100% energy supply for daily cooking in local families. This timely study delivers valuable insights into designing context-specific waste-to-energy systems and integrated waste policies tailored to Maldives’ distinct regions. The framework presented can also guide other SIDS facing similar challenges as Maldives in establishing sustainable, ecologically sound waste management strategies.

Complementarities between wind and wave energies have many significant advantages that are unavailable with the sole deployment of either. Using all available wind speed, significant wave height, and wave period buoy observations over a 10-year period(i.e., 2009–2019), colocated wind and wave energy resources are estimated. Although buoy records are imperfect, results show that the inner Caribbean Sea(CS) under the influence of the Caribbean low-level jet has the highest wind energy resource at ～ 1500 W/m~2, followed by the outer CS at ～ 600 W/m~2 and Atlantic Ocean(AO) at ～ 550–600 W/m~2 at a 100 m height. Wave energy was most abundant in the AO at 14 kW/m, followed by the inner CS at 13 kW/m and outer CS at 5 kW/m. The average and dominant wave energies can reach a maximum of 10 and 14 kW/m, respectively. Asymmetry between wind and wave energy resources is observed in the AO, where wave energy is higher than the low wind speed/energy would suggest. Swell is responsible for this discrepancy; thus, it must be considered not only for wave energy extraction but also for wind turbine fatigue, stability, and power extraction efficiency.

Integrated Transport Planning for small island developing State:A Case Study on Suva City, Fiji

Transportation system of Suva City, the capital city of Fiji is under challenge of managing the growing numbers of private cars, highly competitive modes of public transport and rising costs. An average family directs 15% of their income to transportation. Bus is the main mode of transportation for middle and low income earners. Traditional bus systems, which provide fixed route service, fixed schedule and un-coordinated services through many to one operational service characterize the bus system in Fiji. Over the past decade, major urban centers have experienced continued spatial redistribution of commercial activities and population growth which have impacted the mobility patterns, shifting to multiple origins to multiple destinations. Therefore a mismatch between traditional bus services and spatial redistribution of activities exists. This paper approaches this issue in a case study conducted on two bus routes in the city of Suva, Fiji. The overall direction is the introduction of integrated transport planning for a small island developing country specifically focusing on bus services operating in the area of study by way of an inductive approach. A stated preference survey was undertaken to gauge commuter preferences regarding key bus service attributes such as travel time, bus fare, bus stops and transfers. The concluding section highlight improvements to the current system to provide an efficient bus system.
