Pacific-Gondwana Permo-Triassic Orogenic Belt with Lesser Overprinted Cenozoic Deformation, Eastern Bird Head Peninsula, West Papua, Indonesia

The Paleozoic to Early Mesozoic Pacific-facing active margin of East Gondwana has been shown to extend into the Kemum Block of northern Bird Head Peninsula (western New Guinea), and was associated with Mid Paleozoic orogenic deformation and Devonian to Triassic silicic magmatism and foreland basin deposition. In the Mawi Bay area of the eastern Bird Head Peninsula, the (?) Permian Mawi Complex is a multiply-deformed unit with a pre-Late Triassic D1 deformation formed in an Andean back-arc setting associated with active margin tectonism. The D1 deformation is characterized by recumbent, isoclinal to tight, north-northeast facing folds with an axial planar S1 cleavage formed at a low metamorphic grade, and predated the unconformably overlying Upper Triassic - Middle Jurassic Tipuma Formation. South of the Mawi Complex, the Mesozoic-Paleogene succession of the northern Lengguru Fold Belt is affected by north-northwest trending folds, cleavage, and most of the succession dips moderately to gently to the west-southwest. This deformation is reflected in the underlying Mawi Complex by northwest-trending D2 structures that have folded the D1 folds, and have steeply inclined open to gentle folds, some polyclinal folds, and fault-related folds. The structures in the northern Lengguru Fold Belt may have influenced The Pliocene to Quaternary Central Bird Head Monocline associated with the Kemum Block uplifting in the northern Bird Head Peninsula

Evolution mechanism of permeability of hot dry rock under coupled effect of thermal fatigue and seawater interaction during coastal geothermal development

Using seawater as a heat transfer fluid for developing hot dry rock (HDR) geothermal energy in coastal areas is a frontier of engineering worth exploring; however, only a few studies have considered this research topic. During the development of HDR based on enhanced geothermal system (EGS) technology, the thermal shock fatigue effect of low-temperature seawater on high-temperature reservoirs leads to changes in the permeability of the HDR, notably impacting the reservoir reconstruction design and heat transfer efficiency. Accordingly, the changes in pore structure, pore distribution, porosity, and permeability of HDR in the Guangdong-Hong Kong-Macao Greater Bay Area were investigated based on nuclear magnetic resonance (NMR) techniques and fractal theory after treatment to different temperatures and numbers of thermal shocks due to seawater interaction. The experimental results showed that with an increase in temperature and the number of seawater interactions, the pore structure distribution of the HDR underwent significant changes, with the proportion of mesopores and macropores increasing by 24.29 % and 10.52 %, respectively. Moreover, the porosity and permeability increased with increasing temperature and number of thermal shock cycles, especially above 300 °C. When the temperature increased from 100 °C to 500 °C, the total porosity increased from 0.98 % to 3.85 %, an increase of 292.9 %, while the permeability increased from 10−4 mD to 0.1 mD, an increase of nearly 1000 times. Changes in the pore structure, pore distribution, porosity, and permeability of HDR are caused by multiple damage mechanisms related to high-temperature nonlinear expansion, thermal shock effects, chemical erosion, and fatigue. Additionally, the permeability of the HDR after seawater treatment at the same heat treatment temperature and number of thermal shocks was higher than that after freshwater treatment. At a temperature of approximately 500 °C and 20 thermal shocks, the permeability of HDR under the action of seawater was approximately seven times that of fresh water. Therefore, these results suggest that using seawater as a heat transfer fluid has more advantages in enhancing the permeability of reservoirs.

Impact of the Sino-US Trade War on Factor Endowment in the Guangdong-Hong Kong-Macao Greater Bay Area: A Perspective from Factor Endowment Theory

This study chooses the Guangdong-Hong Kong-Macao Greater Bay Area as the research object to explore the impact of Sino-US trade barriers on the factor endowment of the region. Based on the factor endowment theory, this paper proposes a hypothesis, tests collinearity, and establishes a multiple linear regression model. The results show that the trade barriers between China and the U.S. cannot explain the changes in GBA's factor endowments since the fitting degree is low. The correlation test shows the substitution effect between factor endowments. Based on the data analysis results, Sino-US trade barriers did not affect the factor endowment of the GBA. The possible reasons are the trade deflection and the policy that restrict factor mobility.

Bacterial communities of the threatened Western Pond Turtle may be impacted by land use.

As semi-aquatic species that use both terrestrial and aquatic habitats, freshwater turtles and their microbial communities are especially sensitive to the impacts of habitat disturbance. In this study, we use 16S rRNA amplicon sequencing to characterize the shell and cloacal bacterial communities of turtles in the San Francisco Bay Area. We captured western pond turtles (Actinemys/Emys marmorata) across eight sites located in urban and rural environments, along with invasive red-eared sliders (Trachemys scripta elegans). We assessed differences in western pond turtle bacterial communities diversity/composition between shell and cloacal samples and evaluated how alpha/beta diversity metrics were influenced by habitat quality. We found phylum-level bacterial taxonomic turnover in the bacterial communities of western pond turtles relative to the host tissue substrate samples. Our findings indicate that location identity elicits a high degree of lower-level (i.e. species/genus) bacterial taxonomic turnover. Further, we found that samples originating from good quality habitat had poorer shell bacterial communities but more diverse cloacal ones. The shell bacterial communities of red-eared sliders overlapped with those western pond turtles suggesting the existence of microbial dispersal between these two species. Our results add to our current understanding of turtle symbiont microbial ecology by establishing patterns of bacterial symbiont variation in an urban to rural gradient.

Interdecadal changes in ichthyofauna in a tropical bay with high anthropogenic influences: functional stability despite turnover predominance.

Functional characteristics of species are of great importance for understanding their roles in ecosystems and can be used to detect long-term chances in the environment. We evaluated temporal changes (1983-1985 and 2017-2019) in taxonomic and functional indices of the fish fauna in shallow areas of a tropical bay heavily impacted by anthropogenic activities in recent decades. The hypothesis that functional indices change over time as a result of environmental degradation was tested. Our results showed a significant decrease in species richness and abundance over time, and in functional richness, while others functional diversity indices (divergency, evenness, and originality) remained stable. Thirteen functional groups were detected, some of which contained only one species, raising concerns about the loss of ecosystem functions due to ongoing changes. We also observed an increase in beta diversity over time, which may be the result of a decrease in local richness without leading to regional extinctions. Turnover was the most important process in structuring the fish fauna at the evaluated time scale. The relative stability of the functional structure and the higher levels of turnover seem to be related to the dominance of functional groups, within which species replace each other according to their responses to environmental filters that select for specific functional traits. Incorporating functional diversity indices and beta diversity variations in the fish community helped to enhance the existing information about this coastal system by offering improved estimates of biological diversity through diverse approaches. The predominance of turnover identified in the preset study suggests a dynamic and fluctuating species composition within the habitat. In this sense, habitat preservation should prioritize the protection of diverse habitats to accommodate a broad spectrum of species.

Dispersion and stratification of Per-and polyfluoroalkyl substances (PFAS) in surface and deep-water profiles: A case study of the Biscayne Bay area

Per-and polyfluoroalkyl substances (PFAS) are a group of synthetic chemical compounds known for their persistent, bioaccumulation and toxic characteristics in all environmental compartments. As industrial and domestic applications of PFAS increase, their discharge into water bodies becomes of human and ecological concerns. Our research focuses on providing better understanding on the occurrence, vertical distribution, and dispersion of PFAS in surface and bottom water from inshore and offshore area of Biscayne Bay, Miami, Florida. We screened a total of 30 PFAS from inshore (N = 38) and offshore (N = 48) water samples using a semi-automated solid phase extraction (SPE) followed by instrumental analysis using Liquid chromatography-mass spectrometry techniques (LC-MS/MS). Our findings show a general surface-enrichment and depth-depletion pattern from inshore to offshore area. Average ∑PFAS loadings inshore (surface vs bottom; 29.52 ± 15.26 ng/L vs 21.45 ± 7.85 ng/L) is significantly greater than offshore (surface vs bottom; 5.18 ± 2.68 ng/L vs 2.42 ± 2.11 ng/L). PFOS had the highest mean concentration both inshore (6.36 ± 4.23 ng/L) and offshore (0.83 ± 0.87 ng/L). The most frequently detected (D·F > 91 %) PFAS are Perfluorooctane sulfonic acid (PFOS), Perfluorooctanoic acid (PFOA), Perfluoroheptanoic acid (PFHpA), Perfluorohexanoic acid (PFHxA), Perfluorobutanoic acid (PFBA), Perfluorobutane sulfonic acid (PFBS) and Perfluorohexane sulfonic acid (PFHxS) in surface water samples. PFOS/PFOA >1 suggests that point sources are the major contribution to PFAS burden in the Biscayne Bay. An innovative Inverse distance weighted interpolation (IDW) special modelling approach was implemented to predict the potential contribution of oceanic current on the dispersion of ∑PFAS loadings in surface and bottom profiles from canals (inshore) to offshore areas. This will provide insights into transport mechanisms of PFAS from source emissions, and risk assessments of potential impacts on human and aquatic life in the Bay.

Single-session intervention on growth mindset on negative emotions for university student mental health (U-SIGMA): a protocol of two-armed randomized controlled trial

BackgroundThe university years are a developmentally crucial phase and a peak period for the onset of mental disorders. The beliefs about the changeability of negative emotion may play an important role in help-seeking. The brief digital growth mindset intervention is potentially scalable and acceptable to enhance adaptive coping and help-seeking for mental health needs in university students. We adapted the Single-session Intervention on Growth Mindset for adolescents (SIGMA) to be applied in university students (U-SIGMA). This protocol introduces a two-armed waitlist randomized controlled trial study to examine the effectiveness and acceptability of U-SIGMA in promoting help-seeking among university students in the Greater Bay Area.MethodsUniversity students (N = 250, ages 18–25) from universities in the Greater Bay Area will be randomized to either the brief digital growth mindset intervention group or the waitlist control group. Participants will report on the mindsets of negative emotions, perceived control over anxiety, attitude toward help-seeking, physical activity, hopelessness, psychological well-being, depression, anxiety, and perceived stress at baseline and the 2-week and 8-week follow-ups through web-based surveys. A 30-min digital intervention will be implemented in the intervention group, with a pre- and post-intervention survey collecting intervention feedback, while the control group will receive the link for intervention after 8 weeks.DiscussionThis protocol introduces the implementation plan of U-SIMGA in multi-cities of the Greater Bay Area. The findings are expected to help provide pioneer evidence for the effectiveness and acceptability of the brief digital intervention for university students in the Chinese context and beyond and contribute to the development of accessible and effective prevention and early intervention for university students’ mental health.Trial registrationHKU Clinical Trials Registry: HKUCTR-3012; Registered 14 April 2023. http://www.hkuctr.com/Study/Show/7a3ffbc0e03f4d1eac0525450fc5187e.

Abstract 18643: An Index to Measure Inequity-Health Equity Index for Guideline Directed Medical Therapy Among HFrEF

Background: Heart failure affects 6.2 million adults in the US with 50% five-year mortality. Effectiveness of guideline-directed medical therapy (GDMT), composed by four different medications, has been established to reduce morbidity and mortality for heart failure with reduction ejection fraction (HFrEF), and with strong incremental impact of number of GDMT medications. Despite immense positive evidence, < 5% of patients with HFrEF are on the appropriate target doses of all 4 GDMTs, and there is substantial disparity of GDMT use among race/ethnic groups or socio-economical levels. However, the study to quantify the inequity of GDMT prescription is lacking. Hypothesis: Significant inequity exists in the GDMT prescription among HFrEF. Aims: We derived a health equity index (HEI) for GDMT prescription for HFrEF patients to provide administrators with an assessment tool for evaluating disparity of GDMT use at a large healthcare system covering diverse geographic areas and population in northern California. Methods: HEI for GDMT (3+ GDMT medications) is estimated by ratio of observed-to-expected values. The number of expected patients with 3+ GDMT medication level was derived from a weighted average of subpopulation distribution of the 3+ GDMT prescription for each race/ethnicity and medium income race/medium income level within the population catchment area. Observed 3+ GDMT use was captured from the medication order data in the EHR. HEI > 1.0 represents existence of health inequity. We applied this method to the whole HFrEF population, and then to each of geographic area where the race/ethnicity and medium income level vary significantly. Results: Among 45,222 HFrEF patients 24.6% had 3+ GDMTs, varying from 19% to 29% in 6 geographic areas. The HEI for the whole HFrEF population was 1.33. Further analysis revealed that highest disparity occurred at East Bay area (Oakland area) (1.67), serving large proportion of non-Hispanic Black patient population, and lowest at Palo Alto area (1.27). Conclusion: HEI for GDMT reflects disparity in receiving adequate care for HFrEF population. Substantial disparity was observed in different geographic areas, implying the priority of delivering equitable care to HFrEF should start with the area with highest disparity.

Understanding the compound flood risk along the coast of the contiguous United States

Abstract. Compound flooding is a type of flood event caused by multiple flood drivers. The associated risk has usually been assessed using statistics-based analyses or hydrodynamics-based numerical models. This study proposes a compound flood (CF) risk assessment (CFRA) framework for coastal regions in the contiguous United States (CONUS). In this framework, a large-scale river model is coupled with a global ocean reanalysis dataset to (a) evaluate the CF exposure related to the coastal backwater effects on river basins, and (b) generate spatially distributed data for analyzing the CF hazard using a bivariate statistical model of river discharge and storm surge. The two kinds of risk are also combined to achieve a holistic understanding of the continental-scale CF risk. The estimated CF risk shows remarkable inter- and intra-basin variabilities along the CONUS coast with more variabilities in the CF hazard over the US west and Gulf coastal basins. Different risk assessment methods present significantly different patterns in a few key regions such as the San Francisco Bay area, the lower Mississippi River, and Puget Sound. Our results highlight the need to weigh different CF risk measures and avoid using single statistics-based or hydrodynamics-based CFRAs. Uncertainty sources in these CFRAs include the use of gauge observations, which cannot account for the flow physics or resolve the spatial variability of risks, and underestimations of the flood extremes and the dependence of CF drivers in large-scale models, highlighting the importance of understanding the CF risks for developing a more robust CFRA.

Research on land use pattern change and its influencing factors based on the coupling model: evidence from Zhongshan, China

The change in the land spatial structure affects regional development and stability. In the context of the construction of the Guangdong-Hong Kong-Macao Greater Bay Area, studying the spatial structure changes in its important cities will contribute to the coordinated development of the region. This study uses spatial analysis and coupling models to explore the basic characteristics and evolutionary trends of the land spatial structure in Zhongshan city in 2000, 2011, 2022, and 2035. Through research, it is found that (1) in general, the urban space is divided into different geometric forms by the water network system. The spatial structure of living land is ‘fragmentation-aggregation-aggregation and fragmentation’. (2) Ecological land is concentrated in the southeast and remained relatively stable. Productive land accounts for the largest proportion in Northeast China, becoming the main area of agricultural development. (3) From 2022 to 2035, the area of productive land will increase in different ranges under four scenarios, and the area of productive land will increase the fastest under the urbanization development scenario (UDS). (4) The ecological land area increases only in the ecological protection scenario (EPS), and the area decreases in the other three scenarios. An increase in construction land area occurs in the urbanization development scenario (UDS) and nature development scenario (NDS). (5) The habitat quality of Zhongshan city showed a significant decline from 2000 to 2022. In 2035, the habitat quality will significantly improve in the ecological protection scenario (EPS) and sustainable development scenario (SDS) scenarios, and the ecological regions in Southeast China will be significantly clustered and expanded.

57 Validation of a List Learning Task for Monolingual Spanish Speaking Older Adults

Objective:The prevalence of dementia is higher among minoritized Hispanic/Latino populations in the U.S. Development of linguistically relevant and validated cognitive assessments are urgently needed to adequately address the care needs of this at-risk group. List learning tasks are widely used to evaluate verbal episodic memory and are consistently shown to be sensitive to memory deficits across variousneurologic etiologies. The aim of this study was to validate a Spanish list learning task developed as a linguistically appropriate measure of memory in a diverse sample of Spanish speaking Bay Area older adults who identify as Hispanic/Latino.Participants and Methods:Cognitive scores were assessed in 72 Spanish-speaking older adults living in the Bay Area, California, originally from different countries across South and Central America [(n=29 with CDR scores of 0; n=31 with CDRs of 0.5; and n=12 with CDR of 1), aged 54-96, 30% male)], who completed the Spanish list learning task and a brief neuropsychological battery. The list learning task contains 9 words, 3 words from 3 different semantic categories. Category exemplars were excluded. Administration includes three immediate recall trials, a 30-second delay free recall, 10-minute delay free and cued recall, and yes/no recognition. In this initial validation study, we selected the 10-minute delay recall trial as our primary variable and looked at several indices of construct validity. We hypothesized delayed free recall would: 1) correlate highly with other episodic memory tasks, and minimally with non-memory tests (controlling for CDR sum of boxes), and 2) show step-wise declines as total CDR increased from 0 to 1 (controlling for age, sex, and education).Results:Delayed recall scores of 30-seconds and 10-minutes showed step-wise declines as CDR scores increased (CDR 0 vs. 1, p<0.001 and CDR 0.5 vs. 1, p=0.001). There were no differences in delayed recall between CDR 0 vs. CDR 0.5 (p>0.05). 10-minute delay showed medium-to-large correlations with UDS Craft Story Delayed Recall (partial r =0.45, p<0.001) and Benson Complex Figure Recall (partial r=0.63, p<0.001). Nonsignificant, weaker associations were observed with measures of executive (F Word Verbal Fluency partial r=0.10, Digit Span Forward partial r=0.12), and language (Animal Fluency partial r=0.18) function.Conclusions:Although there is heterogeneity within Hispanic/Latino populations in the U.S., findings begin to support ecological and construct validity of the Spanish list learning task as a measure of verbal memory in older Spanish-speaking adults in the Bay Area. Supporting ecological validity, delayed recall scores significantly differentiated functionally impaired (CDR=1) from functionally mild or unimpaired older adults (CDR=0 or 0.5), though evidenced less sensitivity differentiating unimpaired from mild stages of illness. The Spanish list learning task evidenced strong construct validity as a measure of episodic memory, including strong correlations with other validated memory tasks, and non-significant correlations with non-memory tasks. Larger studies should account for diversity of Spanish speakers in the U.S to see how region of origin, education, and differences between first- and second-generation Spanish speakers influences performance on the task. Future work incorporating imaging markers of brain structure may help further validate the Spanish list learning task as an appropriate measure of memory.

Study on the synergistic development of TCM service trade within the GBA

ObjectivesThis study analyzed the synergistic development of the Traditional Chinese Medicine (TCM) service trade within the Greater Bay Area (GBA) in China, aiming to provide suggestions and references for the development of TCM service trade around the world. MethodsTaking the typical and representative Guangdong, Hong Kong and Macao Greater Bay Area as the research object, this paper focused on four modes of “cross-border supply, offshore consumption, commercial presence, and movement of natural persons”, and explored the current situation of TCM service trade from four macroscopic aspects: political, economic, social, and technological, through case studies. The challenges in the development of TCM service trade were analyzed. ResultsOur study found that the degree of synergistic openness of Guangdong, Hong Kong and Macao needs to be improved. The integration of trade in TCM services is the integration of TCM services with tourism. However, there is a relative lack of human resources in TCM in Hong Kong and Macao, with weak competitiveness of service bases. The resources of TCM services are still under-utilized, and the GBA market of TCM services lacks momentum. ConclusionsWe have come to the conclusion that the GBA need to promptly improve the unified standard system of TCM service trade. Actively building cultivating a “Bay Area GBA brand” for TCM service trade, steadily building a social climate in support of TCM service trade and vigorously promote the development of TCM service trade through digital technology, thus promoting the synergistic development of TCM service trade within the GBA.

The Life and Art of Mary Parks Washington (Fall 2018)

This essay presents a critical biography of African American visual artist Mary Parks Washington, with an emphasis on her creative development from 1942 to 1979. Washington's extant art is discussed in the context of her educational background, social network, and political affiliations, as well as the history of activist curation in the wake of the Black Arts and Black Power movements. As an undergraduate at Spelman College in the 1940s, Washington was mentored by muralist Hale Woodruff, who encouraged her to continue her studies at the Art Students League of New York, Black Mountain College, and the Universidad Nacional de México. These experiences introduced Washington to key figures of the international and American avant-gardes, including Josef Albers, Diego Rivera, and Jacob Lawrence. In 1958, Washington settled down with her family in the Bay Area, where she met poet Sarah Webster Fabio, a leading figure in the Black Arts Movement on the West Coast. Washington and Fabio's collaborative friendship over two decades culminated in 1979's Offshoots of Roots Unknown, a series of “poem-paintings” that elegize Washington's family in early twentieth century Atlanta and, formally, deal with the technical (and ethical) problem of remembering and representing history. Drawing extensively on archival materials from the Auburn Avenue Research Library on African American Culture and History, this essay recognizes Washington's contribution to post-WWII African American art and documents her unique artistic trajectory, traversing aesthetic, social, and political formations from pre-Civil Rights Atlanta to the post-Black Arts Movement Bay Area.

Teaching or learning from baby: Inducing explicit parenting goals influences caregiver intrusiveness.

Caregivers' goals influence their interactions with their children. In this preregistered study, we examined whether directing parents to teach their baby versus learn from their baby influenced the extent to which they engaged in intrusive (e.g., controlling, adult-centered rather than child-centered), sensitive, warm, or cognitively stimulating caregiving behaviors. Mothers and their 6-month-old infants (N = 66; 32 female infants) from the San Francisco Bay Area participated in a 10-min "free-play" interaction, coded in 2-min epochs for degree of parental intrusiveness. Prior to the final epoch, mothers were randomly assigned to receive instructions to focus on (a) teaching something to their infant or (b) learning something from their infant. A control group of mothers received no instructions. Analyses of within-person changes in intrusive behavior from before to after receiving these instructions indicated that mothers assigned to teach their infant increased in intrusiveness whereas mothers assigned to learn from their infant and mothers in the control group did not significantly change in intrusiveness. The study provides experimental evidence that caregivers' explicit goals to teach infants result, on average, in more controlling and adult-centered caregiving behavior.

Artificial Intelligence Improves Patient Follow-Up in a Diabetic Retinopathy Screening Program.

We examine the rate of and reasons for follow-up in an Artificial Intelligence (AI)-based workflow for diabetic retinopathy (DR) screening relative to two human-based workflows. A DR screening program initiated September 2019 between one institution and its affiliated primary care and endocrinology clinics screened 2243 adult patients with type 1 or 2 diabetes without a diagnosis of DR in the previous year in the San Francisco Bay Area. For patients who screened positive for more-than-mild-DR (MTMDR), rates of follow-up were calculated under a store-and-forward human-based DR workflow ("Human Workflow"), an AI-based workflow involving IDx-DR ("AI Workflow"), and a two-step hybrid workflow ("AI-Human Hybrid Workflow"). The AI Workflow provided results within 48 hours, whereas the other workflows took up to 7 days. Patients were surveyed by phone about follow-up decisions. Under the AI Workflow, 279 patients screened positive for MTMDR. Of these, 69.2% followed up with an ophthalmologist within 90 days. Altogether 70.5% (N=48) of patients who followed up chose their location based on primary care referral. Among the subset of patients that were seen in person at the university eye institute under the Human Workflow and AI-Human Hybrid Workflow, 12.0% (N=14/117) and 11.7% (N=12/103) of patients with a referrable screening result followed up compared to 35.5% of patients under the AI Workflow (N=99/279; χ2df=2 = 36.70, p < 0.00000001). Ophthalmology follow-up after a positive DR screening result is approximately three-fold higher under the AI Workflow than either the Human Workflow or AI-Human Hybrid Workflow. Improved follow-up behavior may be due to the decreased time to screening result.

Reimagining the notion of Hong Kong as an education hub: National imperative for higher education policy

This article examines the evolving concept of Hong Kong as an education hub, with a focus on the influence of the Greater Bay Area (GBA) strategy on higher education development. It begins by reviewing the impacts of the policy of developing Hong Kong into an education hub on the city’s educational landscape and global competitiveness. Subsequently, the article investigates the GBA’s role as a subnational higher education region, highlighting the heightened strategic cooperation between Hong Kong and the Chinese Mainland in the higher education arena. The cases of the Chinese University of Hong Kong, Shenzhen and the Hong Kong University of Science and Technology, Guangzhou are examined as examples of cross-border education in the GBA, shedding light on their role in fostering research collaboration and knowledge exchange. The article reimagines the notion of an education hub, underscoring Hong Kong’s transition from a gateway to a radiator, and discusses the implications of this shift for the city’s global and national positioning. Through this analysis, the article examines the dynamics and future prospects of education hub in Hong Kong, particularly within the context of emphasising integration with the Chinese Mainland.

PENINGAKATAN KAPASITAS NELAYAN DALAM MENDUKUNG PENANGKAPAN IKAN BERKELANJUTAN DI PAAP TELUK KOLONO PROVINSI SULAWESI TENGGARA

The management of fisheries access areas is one form of ecosystem-based fisheries management, which integrates marine protected area activities with controlled fishing activities carried out by local fishermen. The objective of sustainable fishing activities in the Kolono Bay Fisheries Access Area is to enhance the capacities of both the local fishermen and the PAAP management. This initiative involves the participation of 15 managing fishermen from five villages: All located in the Kolono Bay area. The project commences with the formation of groups, followed by discussion forums group, guided by a facilitator from RARE Indonesia Sultra. The DFG sessions were held twice, each with distinct themes: (1) issues and challenges encountered by fishermen during fishing activities in Kolono Bay, and (2) concerns related to climate change. Participants exhibited great enthusiasm throughout the engagement, as evidenced by the active sharing of the challenges they have faced concerning their fishing activities in Teluk Kolono during the FGD sessions. The outreach material was presented in simple language to ensure participants' comprehension. In general, it can be concluded that the information provided during this engagement has the potential to enhance the capacities of fishermen engaged in PAAP management in Teluk Kolono to support sustainable fishing.
