This study addresses a critical gap in the understanding of Flood Early Warning Systems (FEWS) within landlocked, resource-constrained contexts by focusing on Chikwawa District, Malawi. The study moved beyond descriptive accounts to provide a nuanced analysis grounding the inquiry into disaster risk reduction theory to assess both the operational and community-level effectiveness of current systems. Employing a mixed-methods approach, this research combines quantitative data from 204 household surveys with qualitative insights from four key informant interviews to triangulate the assessment of flood preparedness, warning dissemination, and community response capabilities. The findings reveal that, while national agencies have established relatively robust monitoring frameworks, significant challenges persist in the final-mile communication loop, resulting in a notable disparity between warning issuance and effective community action. Specifically, issues such as a lack of trust in official messages, inconsistent communication channels, and the absence of well-defined evacuation routes critically hinder the system's overall efficacy. By integrating geographical analysis with on-the-ground perspectives, this paper provides a more complete picture of the obstacles to effective FEWS. The study's key policy implications include the need for more localised and tailored communication strategies, community-based drills to foster trust, and targeted infrastructure investments to enhance last-mile delivery and response capabilities. This work contributes to academic literature by offering a theoretically grounded case study from a landlocked perspective, enriching the global discourse on flood resilience.

Produksi energi primer di Indonesia pada tahun 2018 yang terdiri dari minyak bumi, gas bumi, batu bara, dan energi terbarukan mencapai 1.504 juta SBM (Setara Barel Minyak). Ketergantungan penggunaan bahan bakar minyak (BBM) terutama di sektor transportasi masih tinggi. Komitmen global terhadap pengurangan emisi gas rumah kaca, mendorong pemerintah Indonesia untuk mendukung peran energi baru dan terbarukan. Penilaian siklus hidup (LCA) telah menjadi teknik populer yang diterapkan untuk mengevaluasi dampak lingkungan, konsumsi energi dan emisi GRK (Gas Rumah Kaca) dari produksi biofuel. Untuk mengevaluasi dampak siklus hidup biodiesel, banyak tahapan yang harus dipertimbangkan termasuk perubahan penggunaan lahan, perkebunan, milling, pemurnian, konversi bahan bakar. Sudah ada beberapa penelitian yang melaporkan siklus hidup produksi minyak sawit. Namun, sebagian besar masih berfokus pada emisi GRK dan kebutuhan energi. Oleh karena itu, dalam makalah ini akan menyajikan LCA dengan kategori dampak yang lebih luas dari produksi biodiesel di Indonesia mulai dari fase perkebunan hingga fase produksi. Berdasarkan analisis yang dilakukan, dapat disimpulkan bahwa penyumbang utama dampak lingkungan produksi biodisel adalah penggunaan pupuk pada tahap perkebunan dan proses transesterifikasi pada pabrik biodiesel.

ABSTRACT Climate change threatens sustainability and the environment, like food production, freshwater, and air condition, especially the dryland ecosystem. Seasonal change of the rainy season and prolonged drought put pressure on the farmer community that experienced a decrease in agriculture production and difficulty in land management. This research aims to find out the dry land farmer adaptation in overcoming climate change impact. The method used was the mixed method through observation, interview, and literature review. The majority of elder farmer respondents are 51-70 years old (46,87%), while a farmer in productive age <50 years old are (34,37%). When in detail, farmer respondents in a young age of <30 years old only 6,25%. Farmer respondents in the research location have senior high school graduate education degrees (40,62%). In 2015, an extreme drought occurred, and the total rainfall was only 1,565 mm3, then in 2016, it increased to 3,817 mm3. The change of annual total rainfall, which was great, reached 243%, caused some crops not to adapt well, decreasing agriculture production and farmers' income. Monoculture-based farming patterns impose production costs that continue to increase annually, while contributions to farmer incomes continue to decrease. This matter makes the income decrease from 14% in 2013 to 10,25% in 2018. Besides that, the feasibility analysis of monoculture-based farming also decreased from 4,33 to 2,7. Therefore, the implementation of a multicultural-based farming pattern is the best for adapting the climate change. The multicultural contributes to the farmer income as many as 12,12% and farming business feasibilities of 2,86. Keywords: Agriculture, climate fluctuation, farmers, income, plant

Background: Climate change has become a major global challenge, particularly for vulnerable archipelagic and agrarian countries like Indonesia. Many rice fields in coastal areas—including Cirebon District—are highly exposed to extreme climate events such as prolonged droughts. These conditions disrupt rice farmers’ livelihood systems and reduce their income, threatening their overall livelihood resilience. Methods: This study employed a mixed-methods approach by integrating qualitative and quantitative data to develop a system dynamics model. The model explored interactions between livelihood capital assets, self-organization, learning capacity, and climate conditions. Livelihood resilience was assessed through farmers’ income as a key livelihood outcome. Finding: Model outcomes show that rice farmers’ livelihood systems are not resilient to drought impacts, as their income consistently falls below the ideal threshold. Drought events disrupt livelihoods and lead to income losses, and current farmer-led adaptation efforts are insufficient to improve resilience. Without intervention from government or relevant stakeholders, the livelihood system is projected to remain non-resilient in the future. Conclusion: Rice farmers in Cirebon District lack adequate resilience to cope with drought impacts. Strengthening livelihood resilience requires targeted government interventions to improve critical subsystems, including irrigation governance, crop insurance mechanisms, adaptive farming capacity, and access to climate information. Novelty/Originality of this article: This study provides a system-level understanding of rice farmers’ livelihood resilience by integrating system dynamics modeling with mixed-methods data. It offers a holistic analysis of how livelihood assets, learning capacity, self-organization, and climate stressors interact, and identifies leverage points for policy intervention in drought-prone coastal regions.

Abstract. Ewaldo K, Karuniasa M, Takarina ND. 2023. Carrying capacity of mangrove ecotourism area in Pantai Indah Kapuk, North Jakarta, Indonesia. Biodiversitas 24: 5809-5820. Mangroves are crucial in providing various ecological and economic benefits to local communities. This study focuses on the economic aspect of mangroves by analyzing their potential as a tourist attraction in the Mangrove Ecotourism, Pantai Indah Kapuk (PIK). The objective of this study is to analyze the carrying capacity of the mangroves as a tourist attraction to ensure sustainable tourism development. The study was conducted in the Mangrove Ecotourism area, Pantai Indah Kapuk, from January to March 2023, utilizing a quantitative approach. The carrying capacity of the mangrove ecosystem was assessed using the Physical Carrying Capacity (PCC), Real Carrying Capacity (RCC), and Effective Carrying Capacity (ECC) methods. The calculated values for PCC, RCC, and ECC were 107, 16, and 313 visitors/day, respectively. The analysis revealed that the number of visitors at the PIK Mangrove Ecotourism in 2022 had exceeded the PCC and RCC limits, indicating potential ecological impacts. However, the number of visitors had remained within the ECC limits, suggesting that with proper management, the site could accommodate the current visitor levels sustainably. To achieve long-term sustainability, several initiatives are recommended, such as creating zoning in tourist areas to distribute visitor pressure, increasing the number of field officers to monitor the site, and implementing an online ordering system to manage visitor flow efficiently. The findings of this study contribute to the understanding of the carrying capacity concept in ecotourism and provide valuable insights for the management and conservation of mangrove ecosystems as tourist attractions.

Abstract. Habib S, Karuniasa M, Setyaningsih L. 2025. Vegetation diversity and carbon stock in gold mining reclamation area in Pongkor, West Java, Indonesia. Biodiversitas 26: 4932-4945. Global greenhouse gas emissions set a new record of 57.1 GtCO2e in 2023, an increase of 1.3 percent from 2022 levels. One of the efforts to mitigate carbon dioxide emissions in the mining industry can be done by reclaiming ex-mining land through revegetation. The objective of study was to analyze vegetation diversity and carbon dioxide absorption in the reclamation area of gold mining in Pongkor, West Java Province, Indonesia. The method used for this study was quantitative observation by measuring the number of species, density, frequency and growth of vegetation to calculate diversity index (H'), vegetation biomass and its ability to absorb carbon in the post-mined area reclaimed from 2014 to 2023 covering an area of 21.6 ha. The results of the study showed that the Shanon-Wiener diversity index (H') of tree, pole, sapling and lower-level plant was in the moderate category (1<H'<3). The reclamation area of 21.56 ha was able to absorb carbon dioxide cumulatively of 3,237.98 tons or contributed 5.89% of CO2 emissions by the mining company. Reclamation in the gold mining area is able to restore the ecology of vegetation and absorb carbon dioxide emissions generated from mining activities. However, 10 years of reclamation and revegetation activities still does not offset carbon emissions resulted from the mining activities, suggesting a longer period of restoration with strong monitoring efforts to fully compensate the carbon footprint.

Background: Over the past two decades, Jakarta's built-up area has expanded by approximately 19%, increasing environmental pressures on urban green spaces. The North Kembangan Urban Forest is a green open space intended to support environmental improvement in urban planning. However, its management and aesthetic value remain suboptimal. Enhancing esthetic value aligns with an emerging placemaking perspective that emphasizes user experience and place quality and offers a viable solution to improve green open space (GOS) quality by integrating public perception and expert assessment. Methods: This study used a photo-based questionnaire was administered to 110 respondents and analyzed using Scenic Beauty Estimation (SBE), while development priorities were evaluated through the Analytical Hierarchy Process (AHP) involving nine experts. Findings: The results indicated that photos 5, 7, and 10 showed relatively high aesthetic preferences, with SBE scores of 28.34, 54.09, and 84.28, respectively, although all remained within the moderate aesthetic category. Color, vegetation, neatness, and comfort were significantly associated with aesthetic value, with neatness and comfort showing the strongest correlations (r = 0.97, p < 0.001). The High-Canopy Tropical GOS was beingthe preferred development alternative, with a priority weight of 0.41. Conclusion: These findings highlight the importance of integrating ecological, economic, social aspects, and aesthetic value in GOS planning, particularly in the North Kembangan Urban Forest, to inform more user-oriented and place-sensitive planning of urban green spaces. Novelty/Originality of this article: The study extends the application of the SBE–AHP framework to tropical urban-forest planning by integrating photo-based public aesthetic preferences with expert development priorities in the context of Jakarta. This synthesis results in an aesthetic-driven GOS model underpinned by an environmental science perspective, and contributes to the development of user-centered and place-oriented urban GOS planning.

Background: Rapid urban expansion exerts significant environmental pressure that degrades the quality and distribution of urban green open spaces (GOS). Urbanisation displaces vegetation cover, fragments ecological connectivity, and exacerbates the urban heat island effect, making comprehensive GOS quality assessment a critical planning priority. This study evaluates the quality of GOS distribution at the sub-district level in Semarang City, Indonesia, using the building blue-green index (BBGI). Methods: The BBGI framework integrates five parameters—vegetation index (VI), green index (GI), blue index (BI), impervious surface index (ISI), and high-rise building index (HBI)—weighted through analytical hierarchy process (AHP). Landsat satellite imagery (2010, 2020, 2024) was analysed using normalized difference vegetation index (NDVI)-based land-cover classification in ArcGIS 10.8. Findings: Nearest neighbor analysis (NNA) was applied to characterise the spatial distribution pattern of GOS, and spatial multi-criteria analysis (SMCA) was used to compute composite BBGI scores for all 16 sub-districts. GOS quality in Semarang City is spatially uneven, following a concentric pattern. Only three sub-districts achieved the high-quality category: Gunungpati (BBGI = 5.214), Mijen (4.540), and Tugu (4.522). Four sub-districts fell in the moderate category, and nine sub-districts (56.25%) were classified as low quality, with BBGI scores ranging from 1.479 to 2.608, concentrated in the urban core. The NNA z-score of −44.82 confirms a statistically significant clustered distribution of GOS, indicating systematic spatial inequality. Despite Semarang's relatively high aggregate GOS proportion (44.12%), qualitative distribution remains highly inequitable, constituting a form of environmental injustice for densely populated central districts. A zone management strategy—encompassing conservation, buffer, and intensification zones—is recommended to optimise GOS in accordance with the specific characteristics of each sub-district. Conclusion: This study represents the first application of the BBGI framework at sub-district scale in Semarang City, integrating multitemporal Landsat data, NNA spatial analysis, and AHP-weighted multicriteria evaluation. Novelty/Originality of this article: The findings provide a spatially explicit, evidence-based foundation for differentiated GOS optimisation strategies in rapidly urbanising Indonesian cities.

Background: Climate-induced disasters are testing the institutional limits of law enforcement agencies in sub-Saharan Africa, yet police forces remain peripheral to formal disaster risk governance. Cyclone Idai (March 2019) devastated the Chimanimani District of Zimbabwe, exposing critical gaps in the translation of national climate and disaster policies into ground-level action. This study examines the operational experience of the Zimbabwe Republic Police (ZRP) during the cyclone response, probing the disconnect between formal policy mandates and actual field performance. Methods: A qualitative case study design was used, grounded in semi-structured open-ended questionnaires administered to 15 purposively selected informants, including ZRP officers, government stakeholders, community leaders, and non-governmental organizations. Thematic analysis following Braun and Clarke’s six-stage framework was applied, with triangulation against key national policy and legal documents, including the National Disaster Risk Management Policy and the Civil Protection Act. Findings: All 15 participants (100%) reported that infrastructure collapse, destroyed roads, and bridges were an overriding constraint on police mobility, while 73% cited a total communication network failure. ZRP officers performed broad humanitarian roles, including search and rescue (86.6%), retrieval of the deceased (46.6%), and security of relief supplies (53.3%), operated with severe resource deficits and without climate-specific training. Communities praised the personal dedication of officers while directing frustration squarely at institutional and governance failures. Policy frameworks existed in name but had not been operationalized into routine training, equipment procurement, or coordinated pre-disaster planning. Conclusion: A deep policy-practice disconnect defines Zimbabwe’s disaster response architecture. Effective climate resilience requires the ZRP to be repositioned from reactive responders to proactive participants in national disaster governance, supported by decentralized authority, dedicated funding, and mandatory disaster training. The study proposes a Disaster Adaptive Response (DAR) model to guide this transition. Novelty/Originality of this article: This is the first empirical study to center police institutional capacity within Zimbabwe’s climate disaster governance, advancing the DAR model as an anticipatory framework for law enforcement-led disaster response in low-resource contexts.
