The mangrove ecosystem in the lower Gangetic delta is noted for providing several regulatory services. The major regulatory services include erosion, natural disaster, Phytoremediation, carbon sequestration, siltation, and sea-level rise. Here, we have attempted to develop a mechanism of assessing and ranking the magnitude of regulatory services offered by Sundarban mangroves based on stakeholder’s views on the subject. The respondents were categorized into five major classes namely policy level worker, researcher, fisherman, agriculturist, and local inhabitant. About 295 respondents belonging to these 5 categories were asked about the types of regulatory services and their respective magnitude by ranking the services between 1 and 6. Finally, based on data generated, three separate Combined Mangrove Regulating Service Scale (CMRSS) were assessed for three sectors (western, central, and eastern) of Indian Sundarbans. The basic root for such assessment is contrasting variations between these three sectors based on geographical features, salinity, and biodiversity. The present approach of analysis can be a road map to identify and empirically score the regulatory services of mangroves.

ABSTRAKEmisi CO2 yang terakumulasi di atmosfer menyebabkan terjadinya perubahan iklim secara global. Untuk mengurangi dampak perubahan iklim, salah satu upaya yang dapat dilakukan saat ini adalah meningkatkan penyerapan karbon dan/atau menurunkan emisi di atmosfer. Ekosistem mangrove memiliki fungsi ekologis sebagai pereduksi karbon melalui proses sekuestrasi (C-sequestration). Tujuan dari penelitian ini untuk menghitung kerapatan, kandungan karbon dan serapan CO2 serta mengetahui hubungan korelasi kerapatan mangrove dengan kandungan karbon pada tegakan mangrove. Penelitian dilakukan dengan metode non-destructive sampling menggunakan persamaan alometrik. Pendekatan persamaan alometrik yang digunakan yaitu model alometrik biomassa pohon untuk jenis atau tipe ekosistem mangrove yang sudah tersedia atau dikembangkan di lokasi lain. Hasil pengukuran menunjukkan kerapatan tegakan mangrove di area tanam tahun 2004, 2007, dan 2010 adalah 1460 individu/ha, 1868 individu/ha, dan 2128 individu/ha. Biomassa pada area tanam tahun 2004 sebesar 206,77 ton/ha (103,39 ton C/ha, dan menyerap 379,09 ton CO2/ha). Area tanam tahun 2007 memiliki biomassa 293,73 ton/ha (146,86 ton C/ha, dan menyerap 538,50 ton CO2/ha), dan area tanam tahun 2010 memiliki biomassa 260,02 ton/ha (130,01 ton C/ha, dan menyerap 476,67 ton CO2/ha). Berdasarkan hasil penelitian, kerapatan jenis dan umur tegakan mangrove merupakan faktor yang mempengaruhi besarnya biomassa. Hasil uji regresi-korelasi menunjukkan, perubahan kerapatan mangrove akan berpengaruh secara signifikan pada ekosistem mangrove dalam menyimpan karbon dan menyerap CO2 dari atmosfer. Kata Kunci: Mangrove, biomassa, karbon, kerapatan jenis ABSTRACTEmissions of CO2 that accumulated in the atmosphere causes global climate change.  To reduce the impact of climate change, one of the efforts is increased carbon sequestration. The mangrove ecosystem has ecological function as reducing carbon through sequestration process (C-sequestration). Aimed of this research to calculate the density, carbon content and absorption ability CO2 as well as knowing the correlation of mangrove density with carbon sequestration in mangrove. The method used in this research is use non destructive sampling method with allometric equation. The approach allometric equations were used that tree biomass allometric models for the type or types of mangrove ecosystems that are already available or developed in other locations. The measurement results of mangrove density in planting area 2004, 2007 and 2010 were 1,460 individuals/ha, 1868 individuals/ha, and 2128 individuals/ha. Biomass at the planting area in 2004 amounted to 206.77 ton/ha (103.39 ton C/ha, and absorbs 379.09 ton CO2/ha). Planting area in 2007 have biomass 293.73 ton / ha (146.86 ton C/ha, and absorbs 538.50 ton CO2/ha), and the planting area in 2010 have biomass 260.02 ton/ha (130.01 ton C/ha, and absorbs 476.67 ton CO2/ha). Based on the research results, the density of mangrove species and age are factors that influence the amount of tree biomass. The results of regression-correlation analysis showed, if mangrove density change significantly, it can influence the mangrove ecosystem in carbon sequestration and absorb CO2 from the atmosphere. Keywords: Mangrove, biomass, carbon, mangrove density

Life Skills Education

Life skills education to deal with the climate change and management of natural disaster prevention for students in ethnic minorities boarding high schools are very necessary nowadays. Based on educational activities of life skills, we establish and develop the awareness, attitudes and behavior for students, help them to find the causes and consequences of climate change and the natural disaster so that they shape attitudes and behavior of themselves in adaptation and mitigation due to climate change and natural disasters, as well as conscious propaganda for everyone to perform, toward a better life, a civilized society, meet overall educational goals during the current period. So that, life skills education for the goals of meeting the needs of disaster prevention for students are concerned. However, we not only say doctrinairely but also pay attention to the results of the life skills education due to meet the needs of disaster prevention, by then we form perceptions, attitudes and behavior for students in schools and in society. So there must be coordination between the forces of education in schools with families and society. Therefore, life skills education for students acquire sustainably. Assay results consulted reviews of managers, teachers showed that life skills educational management measures meeting the needs of disaster prevention for the students are necessary and available, suitable with the practice of ethnic minorities boarding high schools.

AbstractIn 2012, Hurricane Sandy hit the East Coast of the United States, creating widespread coastal flooding and over $60 billion in reported economic damage. The potential influence of climate change on the storm itself has been debated, but sea level rise driven by anthropogenic climate change more clearly contributed to damages. To quantify this effect, here we simulate water levels and damage both as they occurred and as they would have occurred across a range of lower sea levels corresponding to different estimates of attributable sea level rise. We find that approximately $8.1B ($4.7B–$14.0B, 5th–95th percentiles) of Sandy’s damages are attributable to climate-mediated anthropogenic sea level rise, as is extension of the flood area to affect 71 (40–131) thousand additional people. The same general approach demonstrated here may be applied to impact assessments for other past and future coastal storms.

Ports constitute a significant influence in the economic activity in coastal areas through operations and infrastructures to facilitate land and maritime transport of cargo. Ports are located in a multi-dimensional environment facing ocean and river hazards. Higher warming scenarios indicate Europe’s ports will be exposed to higher risk due to the increase in extreme sea levels (ESL), a combination of the mean sea level, tide, and storm surge. Located on the west Iberia Peninsula, the Aveiro Port is located in a coastal lagoon exposed to ocean and river flows, contributing to higher flood risk. This study aims to assess the flood extent for Aveiro Port for historical (1979–2005), near future (2026–2045), and far future (2081–2099) periods scenarios considering different return periods (10, 25, and 100-year) for the flood drivers, through numerical simulations of the ESL, wave regime, and riverine flows simultaneously. Spatial maps considering the flood extent and calculated area show that most of the port infrastructures' resilience to flooding is found under the historical period, with some marginal floods. Under climate change impacts, the port flood extent gradually increases for higher return periods, where most of the terminals are at high risk of being flooded for the far-future period, whose contribution is primarily due to mean sea-level rise and storm surges.
