The massive tsunami of December 26, 2004 has had a huge impact on the life of the coastal region. The effects of the tsunami caused damage to occupation settlements, loss of waterside land and destruction of marine biota ecosystems. The coastal region of Aceh Province in Indonesia is the area that has the worst impact followed by the State of Malaysia, Thailand and as a coastal area of India. As a result of a large amount of coastal land experiencing a loss of land mass, erosion is very significant. As a step towards handling coastal areas from greater erosion prevention, the Government of Indonesia in 2005 adopted a policy of handling rehabilitation and reconstruction through the ANTERP (Aceh Nias Tsunami and Earthquake Response Program) program under the BRR (Rehabilitation and Reconstruction Agency) in collaboration with Ministry of Public Work. One of the steps to handling erosion is to protect the coast using the hard structure method such as the construction of a revetment and jetty made from rock armor. This study aims to assess the level of damage and priority of handling of coastal protective structures that have been built in 2009, 2016 and how changes in shoreline occur on the beach location of Alue Naga - Neuheun, which is a coastal area that was greatly affected by the tsunami. Assessments were carried out in three different coastal structures, namely CS-1 locations in the Alue Naga area, CS-2, Lambada Lhok coastal area and CS-3 Neuheun beach area. Guidelines for assessing structure damage and changes in shoreline in the study using the Ministry of Public Work Regulation No. 08/SE/M/2010. The rate of change in shoreline is obtained through computational calculations of the DSAS (Digital Shoreline Analysis System) program using the EPR (End Point Rate) method and NSM for change distance (Net Shoreline Movement).

Bayan IE, Yulianda F, Isdradjad Setyobudiandi I. 2016. Degradation analysis of mangrove ecological function as macrozoobenthos habitat and its management in the Angke Kapuk Coastal Area, Jakarta. Bonorowo Wetlands 6: 1-11. Mangrove ecosystem is a natural resource that has many ecological benefits in the coastal ecosystems, such as become the habitat and food source for terrestrial and marine biota. One of the Indonesian territory which has fairly large mangrove forest area is in the north of DKI Jakarta Province. That is Angke Kapuk coastal which has 327.70 hectares green belt area and scattered in several regions (BKSDA Jakarta, 2003). Mangrove areas in Angke Kapuk play some important roles in the ecosystem, such as became a preservation habitat for the number of species, especially macrozoobenthos. The environmental degradation along regional development, such as tourism, fisheries activity, and industry cause coastal resources which are mangrove areas to become vulnerable. The purpose of this study was to analyze the ecological functions of mangroves as the habitat of macrozoobenthos in Angke Kapuk coastal region, to determine the extent of damage mangrove state and its sustainable management recommendation of mangrove ecosystems in the Angke Kapuk coastal region. This study was conducted in June 2013 and March 2014 at six different stations based on the representation of the condition of the study site. The data collection consists of macrozoobenthos data collection and measurement of water quality parameters, including turbidity, DO, COD, BOD, salinity, pH, nitrate (NO3-N), nitrite (NO2-N), ortho phosphate (PO4-P), and solids suspended (TSS). The results showed that as the macrozoobenthos habitat, ecological functions of coastal mangrove areas in Angke Kapuk was degraded. The state of mangroves ecology in coastal Angke Kapuk was in damage category based on standard mangrove destruction criteria of Minister of Environment’s Decree Number 201 of 2004. The mangrove density was less than 1000 trees/Ha, and its coverage area was less than 50%, so that rehabilitation effort involving the community and manager sectors for the mangrove area sustainable is necessary. Habitat improvement can be applied through cleaning trash in mangrove areas, especially in group A stations that be the most degraded condition and the largest receiving environmental pressures, as well as the group B stations which potentially fall on ecological function degradation due to high development pressures. To plant mangrove vegetation on the site that is ready to be planted also be another way to improve the habitat.

Executive Summary This study presents evidence on time discount rate of forest-dependent communities (FDCs) in the backdrop of the joint forest management program launched by the Government of India in 1990. The study uses data from two regions of the Indian state of Andhra Pradesh—Rayalaseema (a relatively dry forest region with low income) and the coastal region (relatively fertile forest and with higher income). We also identify socio-economic determinants of their patience levels and factors which distinguish the two regions. To elicit individual discount rates of FDCs members and their determinants, we use the choice task design methodology. Members from both regions were found to be highly impatient using the standard choice task design with the revealed time discount rate averaging 800% per annum. Members of FDCs from Rayalaseema were more impatient than their counterparts from the coastal region, although the statistical evidence is weak. We find no association between the income of members of FDCs and their time discount rate for both regions. Membership to caste categories showed a different response in both the regions, with members from the Scheduled Caste category and Other Backward Classes found to have a lower discount rate than those from the Scheduled Tribes category of Rayalaseema region and vice versa for the coastal region. For the coastal region, those with larger family size and heads of households were found to have a lower discount rate.

West Bengal is a maritime state in the northeastern part of the Indian subcontinent with a coastal area of 10,158.22 sq. km. The coastal region consists of the Digha coast, which is noted for its tourism and fish landing activities. We highlight in this paper, a load of nitrate and phosphate during premonsoon in the aquatic phase of Digha for more than three decades (1984 – 2020) to observe the trend of these two variables, which are important components of sewage. A uniform increase in the concentrations of the nutrients is observed except in the years 2009 and 2020. A sudden peak observed for both the nutrients during 2009 may be attributed to Aila, a super cyclone that hit coastal West Bengal on 25th May 2009. The dip in the levels of nutrients during 2020, may be the effect of the COVID lockdown phase in the state during which all the tourism and fish landing activities were completely paralyzed.

<p><strong>English</strong><br />Soybean consumption has grown rapidly, but its production increased at a much lower rate, and as a result its demand can only be met by import. On the other hand, the irrigated land most suitable for soybean development is still in a large potential. To utilize the resource, the government made a special effort through intensification and area expansion program as well. The irrigated lowland at West Java northern coastal region is one of strategic opportunities to boost soybean production based on location, accessibility and land suitability. Soybean is usually produced in the second dry season (July-September), and it is expected to increase farm income, to create rural employment opportunity especially for landless farmer. Some influencing factors for further development are among others good seed availability, irrigation and competition of labor used.</p><p> </p><p><strong>Indonesian</strong><br />Pertumbuhan konsumsi kedelai dari tahun ke tahun terus mengalami peningkatan, sehingga mengakibatkan ketidakseimbangan pertumbuhan konsumsi dan produksi kedelai dalam negeri.

Coastal vulnerability is a condition of a coastal community or society that leads to or causes an inability to face the threat of danger. The level of vulnerability can be viewed from the physical (infrastructure), social, demographic, and economic vulnerabilities. Physical vulnerability (infrastructure) describes a physical condition (infrastructure) that is prone to certain hazard factors. The coastal vulnerability areas can also be interpreted as a condition where there is an increase in the process of damage in the coastal area which is caused by various factors such as human activities and factors from the nature. This research aims to determine the level of coastal vulnerability in Indramayu coastal Regency with a Coastal Vulnerability Assessment (CVA) analysis approach and a Geographic Information System (GIS). Mapping the status of the vulnerability level of the Indramayu coastal area using the CVA method where the index range generated from the calculation of the four physical parameters mentioned above is between 2.887 – 3.651 or are in moderate vulnerability. A higher vulnerability value is found in several locations such as Juntikedokan and Benda villages. It is necessary to develop coastal protection in this area to prevent damage to the coastal area.
