The ecological and socio-economic heterogeneity of these landscapes calls for integrated approaches based on participatory zonation and locally appropriate business models. Primary activities in deep-peat core zones are blocking of drainage canals and revegetation; in shallow-peat buffer zones, forestry and agroforestry on fully rewetted peat, aquaculture, and duck farming; while on surrounding non-peat mineral soils, more intensive tree plantations and agriculture. Community-oriented enterprises require private investment, including microfinance. Blended public and private investment is needed for core-zone restoration. Assuming restoration costs of USD 250-1,000 per ha on moderately drained peat, with emissions of 40tCO2/ha/year, carbon finance could pay for the cost of restoration in under 10 years if emissions are fully or largely abated. To stimulate investment in multiple peatland landscapes we propose a provincial ‘enabling platform’ to support participatory zoning, project design, and monitoring based on common standards and methodologies; technical assistance and incubation for project start-up; multi-stakeholder support for enabling policies, plans and institutions; strengthened finance mechanisms and bundled investments for large and small enterprises; and robust scientific support and knowledge exchange.","PeriodicalId":30661,"journal":{"name":"Journal of Wetlands Environmental Management","volume":"32 1","pages":"77-84"},"PeriodicalIF":0.0,"publicationDate":"2020-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75363025","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to determine the effect of turbidity on the severity of coral bleaching and mortality due to thermal stress and high solar irradiation caused by the 2015 El Nino event. Coral colonies in eighteen permanent bleaching belt transects (50 m x 1 m) in six sites were observed from June to November 2015, coinciding with the 2015 El Nino event. Environmental factors: water depth, sea surface temperature (SST), salinity, turbidity, sedimentation and total suspended solid (TSS) were measured on the same transect. The results of the study showed that the 2015 El Nino event was a major disaster for reefs on the southeast coast of the Kalimantan. Of total colonies (N = 12,954), 45.4% of colonies were bleached and 14.7% of colonies died during the period of July to November 2015. Turbidity, TSS, and sedimentation were negatively correlated with the bleaching mortality index (BMI). Coral bleaching in clear and deep waters occurred earlier and increased rapidly compared to that in turbid waters. However, the severity of coral bleaching in the turbid zone increased dramatically when the turbidity dropped to 5 NTU could provide shade, in which the proportion of dead corals was only 3.5%. The severity of coral bleaching in the turbid zone is not solely due to thermal stress and solar irradiation; it may also be influenced by a history of exposure to high turbidity and low salinity.","PeriodicalId":30661,"journal":{"name":"Journal of Wetlands Environmental Management","volume":"14 2 1","pages":"45-62"},"PeriodicalIF":0.0,"publicationDate":"2020-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83209399","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Being the major staple food, rice production is the main priority of medium and long term development planning in Indonesia. Local rice production is strongly affected by climate conditions, especially in South Kalimantan. Nowadays, the world must adjust to climate change. One of significant effects of changing climate on agriculture is related to productivity. Evapotranspiration is the major cause of loss of water needed, for agricultural requirements. The crop requires effective irrigation system with adequate water amount. The main objective of this research is to analyze the water requirements for the irrigation units in Barito Kuala, South Kalimantan concerning local rice cultivation under the climate change scenarios. Supposed rainfall during the 2050s and 2090s are obtained from four downscaled circulated models and one model for projected temperature under CMIP5 with RCPs 8.5 scenario. Penman-Monteith method was used  to calculate the evapotranspiration value. Based on future effective rainfall water requirement is estimated.  The result shows the impact of climate change on the water irrigation requirement of local paddy cultivation are 56% and 25 % higher than current condition in July and September October respectively.","PeriodicalId":30661,"journal":{"name":"Journal of Wetlands Environmental Management","volume":"65 1","pages":"140-150"},"PeriodicalIF":0.0,"publicationDate":"2019-11-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91362642","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The characteristics of seabed can be studied through the shapes, acoustic reflection pattern, type of substrate or sediment, or by living organisms at the seafloor. In Indonesia, the sub-bottom profiler data was previously only used to measure sea depth. This study was expected to provide overview and updated information about sea depth, seabed and sedimentary layers characteristics based on generated acoustical reflection values and to identify information about abiotic compounding seabed (grain size) used methods Folk 1974 and Spread. Resulted bathymetry data could explain the depth and topography of study areas, seabed characteristics, sea bed sediment classification that were expected to support the determination of shipping tracked lines, underwater pipelines construction, and to determine mineral compounds in the deep sea. The obtained data of field records were in digital *.odc format that is a standard format for BATHY-2010 software. In order to simplify data processing, there would be a series data conversion process into other formats. Data processing of sub-bottom profiling was conducted by Kogeo-imaging software. For more clear and better look than the playback data, the processing data was undergone some steps of treatments such as filtering, stacking and additional gain. Moreover, those data were interpreted at once time with digitizing to interpreted sediment layers. The sea depth of research location was around 52.59-97.03 below the sea surface. Sea bottom formed land (flat) was in the eastern part of the location. Steep basin or Aru Trough was in the western with type substrate of gravelly mud. In general, recorded seismic cut (section) was in the time domain which created vertical velocity distortion and lateral that would produce seismic records that would be different with its actual. Seismic only enabled to detect lithology border if there any acoustical impedance exchange which would be bigger than detectable limit of used seismic waves.","PeriodicalId":30661,"journal":{"name":"Journal of Wetlands Environmental Management","volume":"21 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90248277","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The pilot project has been designed to implement the three aspects of peat restoration, namely rewetting, revegetation and revitalization of society.  Implementation of revegetation is mainly through applying agroforestry by growing agricultural crops in spaces between trees. The objective of present study was to elucidate the suitability of agricultural crops in area of restoration of degraded peatland in South Kalimantan, Indonesia. The suitability of agricultural crops was studied by collecting rainfall and air temperature data from the climatic station of Syamsudin Noor Airport in Banjarbaru, while the nutrient retentions values were determined in the laboratory. Peat depth and drainage class were determined by direct field observations, while peat decomposition level was classified by quantitative method in the field. All collected data were then used to assess the land suitability class for  dry land paddy (<em><span style=\"text-decoration: underline;\">Oriza</span> <span style=\"text-decoration: underline;\">sativa</span></em> L), long bean (<em><span style=\"text-decoration: underline;\">Vigna</span> <span style=\"text-decoration: underline;\">sinensis</span></em> ENDL), cucumber (<em><span style=\"text-decoration: underline;\">Cucumis</span> <span style=\"text-decoration: underline;\">sativus</span></em> LINN), mustard (<em><span style=\"text-decoration: underline;\">Brassica</span> <span style=\"text-decoration: underline;\">rugose</span></em> FRAIN), orange (<em><span style=\"text-decoration: underline;\">Citrus</span></em> sp), <em>stink bean</em> (<em><span style=\"text-decoration: underline;\">Parkia</span> <span style=\"text-decoration: underline;\">speciose</span></em> HASSK), rubber (<em><span style=\"text-decoration: underline;\">Hevea</span> <span style=\"text-decoration: underline;\">brassialiansis</span></em> M.A), and coconut (<em><span style=\"text-decoration: underline;\">Cocus</span> <span style=\"text-decoration: underline;\">nocifera</span></em> L). The productivity data of long bean, cucumber and mustard were obtained by farmer interview. The results showed that most of the agricultural crops were classified as marginally suitable (Class S3).The main limiting factors of agricultural development in this area are low soil pH, low base saturation and peat ripening. Peat depth limits the development of some crops. The above mentioned limiting factors ought to contribute to the low crop productivities in the area.
