Artocarpus altilis, commonly known as breadfruit, is a potential crop adapted to a wide variety of climates and widely spread, including in Indonesia. However, information on how this species can adapt to climate change, in particular in Central Java, is still limited. In Indonesia, Central Java is the center for cultivation areas for many crop species to support the 145 million people living on Java Island. One of the potential crops being developed in Central Java is breadfruit. To assess the suitable cultivation areas for breadfruit, species distribution modeling (SDM) was used to predict the current and future (2050-2070) distribution of breadfruit. Two climate change scenarios, including optimistic RCP2.6 and pessimistic RCP8.5 models, were considered to represent future climate change impacts. Based on the results for both optimistic and pessimistic scenarios, the breadfruit's suitable cultivation areas will expand eastward. Implementing a mitigation climate change scenario and limiting the temperature increase to only 1 °C under RCP2.6 will provide 270.967 km² more of suitable cultivation areas for breadfruit in 2050 and 133.296 km² in 2070. To conclude, this study provides important information on the status and potential cultivation areas for breadfruit, mainly in the Southeast Asia region. The identification of suitable areas will guide land conservation for breadfruit to support food security in this region. [ABSTRACT FROM AUTHOR]

Climate change due to global warming will have an impact on marine and coastal ecosystems, including causing loss of biodiversity and threatening the sustainability of marine and coastal resources. The Sixth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC) made Indonesia, which is a tropical archipelagic state as one of the hotspots that is very at risk of being affected by global warming. This risk is especially experienced by cities on the coast. Therefore the importance of adaptation, especially in dealing with the impacts of climate change that has already occurred. The adaptation process cannot be delayed any longer because the earth's temperature will certainly increase beyond the threshold of 1.5 degrees Celsius in 2030 compared to the pre-Industrial Revolution temperature of 1850. Currently, the global temperature increase has reached 1.1 degrees Celsius. Therefore, Indonesia must immediately make adaptation efforts by utilizing the Blue Carbon Ecosystem which is based on research that blue carbon can absorb and store 100 times more carbon and is more permanent than forests on land. This stored carbon can be stored for thousands of years. Because of this great potential, coastal ecosystems can play many roles as adaptation solutions and mitigation of climate change impacts. Therefore researchers conduct research with the aim of the research is to create Strategies and Adaptation Efforts for Utilizing Blue Carbon Ecosystems: Disaster Resilience, Climate Crisis, and Sustainable Development, with the main target of implementing Resource Based Theory in developing strategies for utilization of Marine Resources, especially Utilization of Carbon Ecosystems Blue in Indonesian marine environment. This research is expected to provide theoretical and empirical evidence related to the development of blue ecosystem utilization strategies, climate crisis, and sustainable development.

Indonesia has the largest tropical peatlands in the Asia-Pacific region and the world's second largest tropical peatlands. Growing concerns on peatland conservation and restoration emphasise the importance of these ecosystems for climate change mitigation and adaptation. Although Indonesia's peatlands are well-studied compared with other tropical countries, there are still uncertainties regarding its peat volume and carbon stock estimations, and how important it is locally and globally. To solve these uncertainties, this study estimated peat volume and carbon stock in Indonesia using the national peatlands data published by the Ministry of Agriculture, Republic of Indonesia and analysed greenhouse gas emissions among the major industrial sectors in the country and global emissions by peatland degradation. Our study posited that anthropogenic disturbance degraded Indonesian peatlands and that the country could become the largest greenhouse gas emitter in the world. Therefore, successful conservation and restoration of Indonesia's peatlands could significantly contribute to global climate change mitigation and adaptation. [ABSTRACT FROM AUTHOR]
