“…The situation is different from the southern coast of the island, which historically was repeatedly hit by tsunamis that emerged from the Indian Ocean (Widiyantoro et al, 2020); and (2) theoretically, the Indonesian Archipelago cannot be crossed by tropical cyclones. The coastal areas of islands in the Indonesian Archipelago that can be affected by tropical cyclones that develop in the Indian Ocean and Western Australia waters are coastal areas of islands facing the Indian Ocean, such as Sumatra, Java, Bali, and the islands of the Nusa Tenggara Islands (Mulyana et al, 2018).…”

Coastal hazard due to wave activity, in the form of coastal erosion, has long been a problem in the coastal area of Ujunggebang. Loss of coastal land in the coastal area has removed a lot of rice fields, settlements, and public facilities. Efforts to maintain the coastline along 3,300 m of the coastal area, by building coastal defense structures (CDS), have been carried out by the central government since 2006 but, until 2015, the CDS that has been built is still only around 1782 m long, in some places the structure is damaged due to wave activity, and in general the structure is not enough to prevent overtopping. Meanwhile, unprotected coastal segments with CDS have experienced significant erosion. The idea of land use change as an effort to adapt coastal hazards, which was conveyed through an idea socialization approach and through showing examples of coastal area management practices to villagers, gave birth to the idea of developing a coastal tourism area in the village as a complementary measure for the existing coastal defense structure. Although the main problem faced- coastal erosion- has not been resolved, the development of the tourism area has been recognized by the local government as successfully changing the life of the village community.

“…Conversely, the effect of natural disturbances on BCEs in Karimunjawa is perceived to be the least concerning threat as reflected in the results (see Table 4). Unlike the Philippines, the average number of tropical cyclones in Indonesia is seven (7) per year or about 9% of the average number of cyclones globally, because, in principle, tropical cyclones do not cross the country as they will always move away from the equator [64]. The lack of personal experiences and observations on the effect of natural disturbances on BCEs likely influenced residents' perceptions.…”

How Blue Carbon Ecosystems Are Perceived by Local Communities in the Coral Triangle: Comparative and Empirical Examinations in the Philippines and Indonesia

et al. 2020

Blue carbon ecosystem (BCE) initiatives in the Coral Triangle Region (CTR) are increasing due to their amplified recognition in mitigating global climate change. Although transdisciplinary approaches in the “blue carbon” discourse and collaborative actions are gaining momentum in the international and national arenas, more work is still needed at the local level. The study pursues how BCE initiatives permeate through the local communities in the Philippines and Indonesia, as part of CTR. Using perception surveys, the coastal residents from Busuanga, Philippines, and Karimunjawa, Indonesia were interviewed on their awareness, utilization, perceived threats, and management strategies for BCEs. Potential factors affecting residents’ perceptions were explored using multivariate regression and correlation analyses. Also, a comparative analysis was done to determine distinctions and commonalities in perceptions as influenced by site-specific scenarios. Results show that, despite respondents presenting relatively high awareness of BCE services, levels of utilization are low with 42.9–92.9% and 23.4–85.1% respondents in Busuanga and Karimunjawa, respectively, not directly utilizing BCE resources. Regression analysis showed that respondents’ occupation significantly influenced their utilization rate and observed opposite correlations in Busuanga (positive) and Karimunjawa (negative). Perceived threats are found to be driven by personal experiences—occurrence of natural disasters in Busuanga whereas discerned anthropogenic activities (i.e., land-use conversion) in Karimunjawa. Meanwhile, recognized management strategies are influenced by the strong presence of relevant agencies like non-government and people’s organizations in Busuanga and the local government in Karimunjawa. These results can be translated as useful metrics in contextualizing and/or enhancing BCE management plans specifically in strategizing advocacy campaigns and engagement of local stakeholders across the CTR.

“…The peak of this cyclone was on 27 November. It hit the southern coast of Yogyakarta Province, causing extreme rainfall of up to 175 -250 mm/day and severe flooding in Bantul, Gunung Kidul, Wonogiri, and Pacitan districts (5). The cyclone was formed by a combination of small-scale clouds and low-pressure centers on the south coast of East Java, as well as the presence of low-level jets that moved towards the southern coast of Java Island (6).…”

Introduction: The ‘Cempaka’ Tropical Cyclone hit south Java in November 2017, causing heavy rainfall and severe flooding. Changes in climate variability and extreme weather events may shift the geographic and seasonal patterns of neglected tropical diseases such as leptospirosis. This study analyses the Spatiotemporal pattern between flooding, weather, and human leptospirosis cases after a tropical cyclone. Methods: This was an ecological study that collected monthly flooding data, weather data, and human leptospirosis data cases per village from November 2017 to October 2018, a year after the ‘Cempaka’ Tropical Cyclone in Bantul. Spatio-temporal analyses were calculated to 0-3 months lag by Pearson's correlation, spatial mapping, and time-series graphs. Results and Discussion: As many as 99 people infected with leptospirosis were found in all 75 villages in Bantul. The villages affected by flooding were 44% and leptospirosis cases spread in 68% of villages. A 1-month lag (r = 0.6849; p < 0.05) and 3-months lag (r = 0.6666; p < 0.05) of relative humidity along with a 1-month lag (r = 0.7451; p < 0.05) and 3-months lag (r = 0.8561; p < 0.05) of rainfall were found to be correlated to human leptospirosis cases. Heavy rain due to the Cempaka Tropical Cyclone caused flooding and transmission of Leptospira bacteria into the water and heightened contact between humans, animals, and the environment. Conclusion: It is found that flooding, relative humidity, and rainfall after the Cempaka Tropical Cyclone would be followed by human leptospirosis outbreaks 1 and 3 months later. Cross-sectoral cooperation of public health authorities should integrate climatic information as an early warning for disaster-prone areas and community groups at risk.
