Tourism development has been promoted as an alternative livelihood to reduce the dependence of small island communities on declining marine resources. It is often central to emerging agendas around marine planning and the blue economy. However, relatively little is known about how communities perceive tourism development as an alternative and potentially sustainable livelihood in their area and its implications. This qualitative study tracks a governance system in transition and analyzes the factors perceived by stakeholders to be driving and hindering the adoption of tourism-based livelihoods on small islands in UNESCO’s Taka Bonerate Kepulauan Selayar Biosphere Reserve (Indonesia). The findings indicate that, despite a series of tourism-enhancing investments and initiatives and the positive attitudes of local communities towards it, tourism is not a direct route towards sustainability for small island communities. The benefits of tourism are perceived to be unequally distributed. The lack of education and skills limits participation in new job opportunities, and the incentives to continue destructive fishing inhibits livelihood transition to tourism. The article concludes that tourism cannot be assumed to generate simultaneous benefits for conservation and development without more equitable benefit sharing, the meeting of basic needs in communities, and addressing the drivers of unsustainable livelihoods.

Praptiwi RA, Saab R, Setia TM, Wicaksono G, Wulandari P, Sugardjito J. 2019. Bird diversity in transition zone of Taka Bonerate, Kepulauan Selayar Biosphere Reserve, Indonesia. Biodiversitas 20: 819-823. Conservation management in the buffer and transition zones of Biosphere Reserves play an important role in ensuring enhanced core zone protection. Tambolongan and Polassi are two islands located in the administrative region of South Sulawesi, Indonesia, and part of the transition zone area of UNESCO’s Taka Bonerate-Kepulauan Selayar (TBKS) Biosphere Reserve (BR). These two islands can be considered as some of the most populated islands in the region, containing a variety of human activities. These human activities, such as the ever expanding agriculture and the building of human habitation have put pressures toward ecosystem and species conservation in the BR. Bird are often the focus of conservation efforts, due to their roles in supporting the ecological functioning of their habitats. This study aims to provide baseline data of bird diversity in Tambolongan and Polassi that can be used as a proxy indicator of ecosystem health and input to conservation strategies within the BR area. A Visual Encounter Survey (VES) method is used to examine bird diversity index. Results from the observation recorded a total of 29 species were found in both islands, with 5 listed as protected species and 3 categorized as migratory species. The comparison between the two islands showed that the bird diversity index (H’) differs only slightly (H’Tambolongan=2.98; H’Polassi=2.71). This study provided the initial attempt in understanding the role of habitats or land cover types, guild types and human interferences in determining the diversity of bird population - and related ecosystem health - in the area. Such knowledge is essential in providing the information necessary for sustainable management practices. This work represents the first study to inventorize avian species diversity in the transition zone of TBKS BR.

In conventional water treatment processes, where the coagulation and flocculation steps are designed to remove particles from drinking water, cyanobacteria are also concentrated into the resultant sludge. As a consequence, cyanobacteria-laden sludge can act as a reservoir for metabolites such as taste and odour compounds and cyanotoxins. This can pose a significant risk to water quality where supernatant from the sludge treatment facility is returned to the inlet to the plant. In this study the complex processes that can take place in a sludge treatment lagoon were investigated. It was shown that cyanobacteria can proliferate in the conditions manifest in a sludge treatment lagoon, and that cyanobacteria can survive and produce metabolites for at least 10 days in sludge. The major processes of metabolite release and degradation are very dependent on the physical, chemical and biological environment in the sludge treatment facility and it was not possible to accurately model the net effect. For the first time evidence is provided to suggest that there is a greater risk associated with recycling sludge supernatant than can be estimated from the raw water quality, as metabolite concentrations increased by up to 500% over several days after coagulation, attributed to increased metabolite production and/or cell proliferation in the sludge.

A bloom of the non-toxic cyanobacterium Romeria elegans in waste stabilisation ponds (WSPs) within Angaston waste water treatment plant (WWTP) has posed an unprecedented treatment challenge for the local water utility. The water from the WSPs is chlorinated for safety prior to reuse on nearby farmland. Cyanobacteria concentrations of approximately 1.2 × 106 cells mL−1 increased the chlorine demand dramatically. Operators continuously increased the disinfectant dose up to 50 mg L−1 to achieve operational guideline values for combined chlorine (0.5-1.0 mg L−1) prior to reuse. Despite this, attempts to achieve targeted combined chlorine residual (CCR) failed. In this study, samples from the waste stabilisation pond at Angaston WWTP were chlorinated over a range of doses. Combined chlorine, disinfection by-product formation, cyanobacteria cell concentration, Escherichia coli inactivation, as well as dissolved organic carbon and free ammonia were monitored. This study shows that, in the occurrence of cyanobacterial blooms, CCR does not directly suggest pathogen removal efficiency and is therefore not an ideal parameter to evaluate the effectiveness of disinfection process in WWTP. Instead, E. coli removal is a more direct and practical parameter for the determination of the efficiency of the disinfection process.
