Abstract

The current climate change is caused by anthropogenic activities involving energy and industry usage that affect the temperature and climate of the Earth. The Paris Agreement on climate change is a commitment by some countries to act to address climate change by developing sustainably and emitting low levels of carbon dioxide (CO2). Changes in the oceans include temperature increases, acidification, and changes in currents, leading to decreased productivity in fishing and aquaculture. Integrated mangrove shrimp farming, known as silvofisheries, has been recognized as environmentally friendly cultivation. The implementation of silvofishery is a form of mangrove ecosystem management that integrates ecology and economics. An economic and ecological valuation is needed in the Vannamei shrimp farming business. Therefore, this study aims to build an economic model of mangroves and shrimp farming. The data were analyzed and simulated using Systems Dynamic. Based on Business as Usual (BAU) simulation predictions for the 2023 mangrove area of 267 hectares, the best scenario for the mangrove area of 2033 is 1,770 hectares, the total economic value of shrimp of Rp 49,300,000,000 and the total economic value of mangrove is Rp 77,175,000,000. This research results in a potential trade-off between intensive shrimp farming businesses and mangrove rehabilitation to maintain a business's sustainability and the environment's carrying capacity.

Abstract

The payment for ecosystem services (PES) scheme in the Cidanau Watershed, Banten Province, Indonesia has not yet quantified and reviewed its livelihood impacts on its providers after two decades of implementation. Therefore, this study maps the livelihood sustainability of PES farmers and non-PES farmers in the Cidanau Watershed using capital indexes based on the five livelihood capital assets of the DFID’s sustainable livelihood framework. The research used a quantitative method to formulate the livelihood capital indexes (LCI) as approximates to the subjects’ livelihood sustainability based on their livelihood information and draws implications from the results thereof. A total of 168 agroforestry farmers both from PES and non-PES groups were interviewed across 12 villages in the upstream area. The results show that both PES and non-PES groups share the same pattern of capital assets sustainability with the PES group having a slightly higher human capital asset. The overall LCI calculated for the PES and non-PES groups are 0.445 and 0.48, respectively. The livelihood of both groups is deemed as not yet sustainable. The farmers would have to develop their financial and human assets to attain more sustainable livelihoods and prepare themselves for adopting new types of PES in the future.

Abstract

Background: Indonesia is still an energy importer, especially in the form of crude oil and fuel products to meet the needs of its industrial sector. The reduced production of fossil energy, especially oil, as well as the global commitment to reducing greenhouse gas emissions, has prompted the Indonesian government to continue to support the role of new and renewable energy. The production of palm oil-based biodiesel is faced with a number of environmental problems, which may occur from the release of emissions during the production of FFB (Fresh Fruit Bunches), CPO (Crude Palm Oil), and biodiesel. Therefore, the purpose of this research is to compile an LCI (Life Cycle Inventory) covering the production of FFB, CPO, and biodiesel; analyze the environmental impact of the CPO bodysel production process which includes CO2 (eq) emissions, acidification and eutrophication; and develop a life cycle concept for biodiesel production from palm oil as a renewable energy. Methods: The method used in this study is a combination of quantitative LCA (Life Cycle Assessment) and AHP (Analytical Hierarchy Process) and qualitative. Findings: The results of this study are LCI in 1 ton of biodiesel consisting of NPK fertilizer of 141.1 Kg; herbicide (0.25 Kg); water (1578 m3), diesel oil (25 Kg); fresh fruit bunches of 5.67 tons; electricity of 33.8 kWh, POME (Palm Oil Mill Effluent) (3,47 m3), CPO needed for biodiesel conversion of 1.17 tons; methanol (0.41 tons), and 0.01 tons of Sodium Hydroxide. The total CO2 emission (eq) of biodiesel production from palm oil is 1489 Kg CO2 (eq), eutrophication is 1.12 Kg PO43- (eq) and acidification is 3.06 Kg SO2 (eq). With the largest contribution of CO2 (eq) emissions in CPO production and the contribution of eutrophication and acidification in oil palm plantations or FFB production (Fresh Fruit Bunches). Environmental hotspot of LCA, CO2 (eq) emissions from palm oil biodiesel production show that 53% mainly comes from POME (Palm Oil Mill Effluent) waste, other contributors are NPK fertilizers (23%), methanol (18%), and diesel oil (7%). Hotspot eutrophication showed that 61% mainly came from NPK fertilizer, methanol (20%), diesel oil (11%), and POME waste (8%). Hotspot acidification showed that 48% mainly came from NPK fertilizers, methanol (28%), POME waste (13%), and diesel oil (11%). Conclusion: The concept of a biodiesel production life cycle can be applied with the best alternative utilization of POME waste with a priority weighting of 0.357 and a CO2(eq) emission criterion of 0.494. From the optimization of the life cycle of biodiesel production with the use of POME, the potential for emission reduction is 667.2 Kg CO2 (eq). Novelty/Originality of this Study: This study's novel application of LCA evaluates the environmental impacts of biodiesel production from palm oil in Indonesia, identifying critical hotspots in CO2 emissions, eutrophication, and acidification. Additionally, it proposes an innovative optimization approach by utilizing POME to significantly reduce greenhouse gas emissions, highlighting a viable path for enhancing the sustainability of biodiesel production.

Abstract

Background: Peatland ecosystems play an important role in the hydrological cycle and carbon cycling. In Indonesia, peatlands store about 28.6 gigatonnes of carbon which is equivalent to 10 years of global fossil fuel emissions. Peatlands act as a water storage during wet seasons and slowly release water during dry seasons to maintain river discharges and hydrological balance. However, climate change induced prolonged drought has increased peatland dryness in recent decades which elevate the risks of unwanted peatland fires. During El Nino-induced drought in 2015, over 2.6 million hectares of forest and land burned, emitting 0.81–1.4 gigatonnes of greenhouse gasses. The extreme fires damaged biodiversity, degraded water quality and displaced thousands of locals. This study aimed to analyze peatland wetness as an indicator of fire occurrences in forest and land fires (FLFs) in Riau, Indonesia by examining the relationship between degree of peatland wetness derived from satellite imagery and hotspots data. Methods: Peatland wetness was estimated from microwave backscattering coefficients at several RadarSat synthetic aperture radar (SAR) wavelengths and cross validated with water table depth measurements from 120 monitoring wells. Hotspots data between 2015-2020 were obtained from NASA's MODIS active fire product. Findings: Preliminary results showed significant negative correlations between peatland wetness and numbers of hotspots in peatlands, with more hotspots occurring in drier peatlands compared to wetter ones. This implies that maintaining peatland hydrological functions through continuous saturation is pivotal to prevent severe peatland wildfires under future climate change. Conclusion: Conservation efforts to restore hydrological balance in degraded peatlands through re-wetting strategies are recommended. Further research utilizing machine learning algorithms to produce high-resolution peatland wetness maps can improve fire risk monitoring in peatlands. Novelty/Originality of this Study: This study introduces the novel concept of utilizing peatland wetness as a key indicator for predicting and mitigating forest and land fires in Indonesia, particularly in Riau Province. By combining peatland moisture and temperature data, the research establishes threshold values to better predict fire risks and guide timely mitigation efforts, thereby enhancing the efficiency and effectiveness of FLF response activities.

Abstract

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

Abstract

Background: With more than 40% of Indonesia's oil palm land under its management, smallholders still face challenges on the low land productivity and certification achievement. Methods: This research aims to develop a certification concept capable to increase the smallholders’ land productivity through descriptive statistics, grounded theory, content analysis, and Analytic Hiearachy Process. Findings: This research finds that ISPO and RSPO certified smallholders achieved 82% higher land productivity than the average conventional ones, in line with their compliance with certification and consistent GAP application. Fertilisation needs to be prioritised to increase productivity, with the GAP Application and Monitoring (RSPO) and Plant Maintenance (ISPO) as the supporting certification criteria. Conclusion: Synergy between ISPO and RSPO has a chance to increasing land productivity through certification compliance, hence accelerating smallholder certification achievement which would reduce deforestation rates from oil palm expansion. Novelty/Originality of this article: This study introduces a certification concept that combines ISPO and RSPO standards to enhance smallholder land productivity. It emphasizes the integration of fertilization, GAP application, and plant maintenance as key components for boosting productivity while ensuring certification compliance, offering a novel approach to reducing deforestation rates in Indonesia's oil palm sector.
