This study on the Songor Ramsar and UNESCO Man and Biosphere Reserve in Ghana seeks to ascertain management method to promote sustainable management of wetlands. The findings clearly indicated that good management practices are employed in the management of the Songor Ramsar Site. The current approaches to management have focused on the harmonious fusion of modern scientific strategies and cultural and traditional methods. In the Songor Ramsar and UNESCO Man and Biosphere Reserve, traditional authorities have enacted traditional rites such as sacred groves and totems in the Ada East District which are strictly enforced to provide traditional regulatory support for their protection while modern conservation approaches in the Songor Wetland management utilizes all the laws in legal protected areas in Ghana. Management also embark on training programmes for users of the wetland resources in sustainable resource utilization to improve economic livelihood. Increased public education and sensitization on the economic importance of the Ramsar Site and the negative impact of environmental degradation has been part of the management strategies. The Public education is on environmentally sound management of waste within the Ramsar Site since the underlying causes of environmental degradation in the Songor Ramsar Site are mainly improper waste disposal, poor attitude of residents toward environmental conservation, wildfires and shoreline recession, inadequate public education on the impact of environmental degradation, fishing, and farming activities. The other factors identified include overgrazing, over exploitation of mangroves, predation, poaching and over fishing, and uncontrolled sand and salt winning

The study aimed to find out whether Pasteurella multocida bacteria isolated from buffalo in HSU (Hulu Sungai Utara) is the cause of SE (Septicema epizootica) disease in swamp buffaloes using Koch Postulates. Total of 10 Balb-C mice aged 2 weeks were infected with 100 μl culture containing 4 x 108 CFU (1.5 McFarland Scale) P. multocida subcutaneously in the neck , and observed every 4 hours until the animal died. Samples were taken from the spleen, lungs, and heart with different times of death within 15 hours, 35 hours, and 59 hours with sterile swab cotton. Samples were grown on a nutrient broth medium (NB), inoculated on a soy trypticase agar (TSA), and incubated for 24 hours at 37 ° C. Separate colonies were stained with Gram and spore staining. The colonies were tested by catalase, biochemical, indol motility (SIM) sulfite, confectionary, and planted on Mac Conkey Agar media. P. multocida was identified following Carter's method of showing lung, spleen, and positively infected P. multocida samples. It was concluded that P. multocida bacteria isolated from buffalo in HSU are pathogenic and can cause SE disease.

The objective of this study was to determine the changes in the basic soil chemical properties including pH, electrical conductivity (EC), available phosphorus (P), dissolved organic carbon (DOC) and inorganic Nitrogen (NH 4 + -N and NO 3 - -N) after approximately 15-40 years land use change from rice paddy field to orchard, wetland and upland in northeast Japan. Five land use change fields were investigated, including, forest, rice paddy, orchard, wetland and upland near Kumagai shrine, Shonai-machi, Yamagata, Japan. Soil samples were collected from surface layer (0-15 cm) and subsurface layer (15-30 cm) in October 2015. Soil chemical properties of pH, EC, available P, DOC and inorganic N (NH 4 + -N and NO 3 - -N) were analyzed on air-dried samples. The pH increased significantly in the upland after 15 years conversion from rice paddy in both layers, with other land use changes only increasing pH in subsurface layer. EC significantly decreased in the surface layer of orchard and upland fields and in subsurface layers of all the converted fields. Available P significantly decreased in the converted fields, except in the upland subsurface layer. DOC amounts were not significantly different after land use changes from paddy fields. The NH 4 + -N decreased significantly only in the surface layer of upland, while NO 3 - -N increased significantly only in the surface layer of wetland. Significant changes in soil properties were observed after 15 years conversion to upland and 40 years conversion to orchard and wetland from former rice paddy field in this study.

This study aims to determine the effect of the type of packaging and storage time on the chemical composition and rice cooking quality by utilizing the respiration generated heat of freshly harvested rice. “Siam Pandak” variety of freshly harvested rice stored in black plastic bag and tarpaulin with storage time of 0, 1, 2, 3, 4 and 5 days. The results showed that the accumulation of respiration heat of freshly harvested rice during storage is only capable of raising the temperature in the packaging up to 28 – 31°C, slightly higher than room temperature ranging between 26 – 29°C. Types of packaging and storage time could increase water absorption capacity, protein and fiber contents; and reduce fat and carbohydrate contents. The increase in water absorption capacity was obtained in black plastic bag with storage time of one day, which amounted to 298.27% (an increase of 27.74% compared to control), the highest protein content with storage time of two days with a protein content of 8.56% (an increase of 7.31% compared to control), fiber content in the tarp packaging with storage time of five days, which amounted to 2.40% (an increase of 96.46% compared to control).

The production of mocaf flour in MSME scale in South Kalimantan area was not feasible considered from its business feasibility hence the multiple effect was unmeasured based on its industry existence. Mocaf flour production derived from cassava, which is a plant that not only match on dry land but also in the wetlands of South Kalimantan, can not be oriented consumer as a substitute for wheat flour for common food products in the society. Therefore, further research refers to aspects mocaf flour premium for health. This objective of this research was to increase the society consumption of mocaf flour for the healthy reason related to the trend on negative effect from high level of gluten in wheat flour. The laboratory test showed the result that supports mocaf product for health. With this consideration then mocaf processed product have potentials to bedeveloped though serious marketing effort is required due to infamiliarity of the mocaf flour especially in South Kalimantan area. Difference test result showed that prospects, indeed, haveintention to purchase mocaf-based processed products for healthy reason.

Muara Sugihan is one of the tidal swamp areas for rubber plant cultivation in South Sumatera. A preliminary survey of the land suitability in 2012 described that there are two main problems, the shallow groundwater problem and low pH (2,87-3,05) between 40-100 depth that indicates the presence of pyrite layers. In the prior of planting, the water drainage has been done to maintain the water table. However, the water drainage was excessive so that water table reach 66 cm from soil surface hence aerobic condition resulted in oxidation of pyrite layer. The method used in this study was survey method consist of measur ing the girth of 2 years old rubber plants and sampling of soil, leaves, and water on the trench and the river which indicated the presence o f pyrite layers o n tidal swam p area, Muara Sugihan. The result showed that the growth of the rubbe r plants was inhibite d , where the girth was 10 cm, while on optimal dry land they normally reached 18 cm. Leaf nutrient analysis showed there was deficient of P, K, and Zn, while on soil analysis showed a low P content. T he pyrite was leach from the soil and a c cu m ulat e into water drainage will lead to low pH of water. This problem can be solved by water management improvement.
Muara Sugihan是南苏门答腊橡胶植物种植的潮汐沼泽地区之一。2012年的土地适宜性初步调查显示，该地区存在两个主要问题，即浅层地下水问题和40-100层之间的低pH值(2,87-3,05)，表明黄铁矿层的存在。在种植之前，已经进行了排水，以保持地下水位。但由于排水过多，地下水位达到离地表66 cm，好氧条件导致黄铁矿层氧化。本研究采用的调查方法是测量2年生橡胶树的周长，并在沟和河上取样土壤、树叶和水，表明在Muara Sugihan潮汐游泳区存在黄铁矿层。结果表明，橡胶树的生长受到抑制，其周长为10 cm，而在最佳旱地，橡胶树的周长通常达到18 cm。叶片养分分析显示磷、钾、锌缺乏，土壤养分分析显示磷含量低。当黄铁矿从土壤中浸出后，向排水中加入1立方米的黄铁矿会导致水的pH值降低。这个问题可以通过改善水管理来解决。

The research aimed to (1) describe changing biomass during the burning process, (2) characterize the nutrient loss due to biomass burning, (3) analyse the financial loss of nutrient transfer, and (4) compare farmer’s income among three land typologies. This research was conducted in tidal wetlands Talang Sepucuk, OKI District, South Sumatra with a slope of 0-3 %. Three selected land typologies (B, C and D) are located in the area adjacent to one another with distance < 1.200 m. The natural vegetation data and paddy yields was recorded by squares method, i.e. 25 x 25 m at each study site, dried and weighed and analyzed in the laboratory. The research resulted that the nutrient transfer due to biomass burning was in range of Rp 49.98-51.62 Mills/ha/year. The farmer’s income of the sonor system was very small (Rp 3.61-3.97 Mills/ha/year), it was only about 7 % of the total financial loss of nutrient transfer). The remaining value (93 %) is beyond the capacity of farmers to harvest natural resources. This value (93 %) is classified as one of the biggest negative impact of the sonor system to be paid by the all people. The government must intervene to make the public policy by giving direct subsidy to farmers NOT to burn biomass in the sonor system with compensation of at least 2 (two) times of farmer’s income from the sonor system (around Rp 7.66 Mill. Rp/ha/year). If farmers still continue to apply the sonor system by using fire, then there is very little opportunity for us to manage the nutrients loss due to biomass burning. The preventive and proactive approach is the best way how to manage the land resources.

The research aimed to analyze selected properties of peat degradation on different land uses and the sustainable management. The research area is located in the lowland dome peats in the catchment basin of Sibumbung River and Sibotak River in Sub District of East Pedamaran, OKI South Sumatra. The research method used an experimental design of Randomized Completely Block Design with two Blocks and five treatments (Site A: intercropping between oil palm and pineapples; Site B: oil palm plantations, Site C: peat forest; Site D: swamp bush; Site E: swamp grass). The research resulted that drainage and land uses decrease some properties of peats, namely C/N ratio, total pore space, fiber and ash content as well as organic C on cultivated peats and are significantly different at level of 5% compared with uncultivated peats. Bulk density increased due to peat compaction and groundwater table on cultivated peats, which is getting deeper, and significantly different compared with uncultivated peats. All soil series do not show any change because of drainage and different land uses. Sustainable peat management can be implemented through three approaches, namely managements of water, soil and crops.

Bangladesh is the largest delta in the world. Geographical location and seasonal diversity have made this country unique. Tanguar Haor as a Ramsar site is famous throughout the world with a reservoir of aquatic biodiversity. Due to availability of water flow throughout the year it has reached biodiversity compared to other haors in Bangladesh. In every winter, this haor becomes sonorous with the presence of thousands of migratory and resident birds. A lot of aquatic plants are floating and some are submerged. These aquatic plants decompose with seasonal shift and make the soil fertile. Numerous organism with food and shelter provided by these aquatic plants. Various species of amphibians and reptiles can also be seen in this vast haor. It has merged with the life and tradition of local people. Also human habitation has increased around the haor since the middle of the last century. About 12,870 ha water body have lost from 23,230 ha during last 60 years. Per year, 1.17% of water body have been lost in Tanguar Haor from 1955 to 2015. As a result, population of birds and wildlife is decreasing alarmingly due to the disturbance in the natural balance of the wetland ecosystem.

As a result, population of birds and wildlife is decreasing alarmingly due to the disturbance in the natural balance of the wetland ecosystem.","PeriodicalId":30661,"journal":{"name":"Journal of Wetlands Environmental Management","volume":"21 1","pages":"34-42"},"PeriodicalIF":0.0,"publicationDate":"2017-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85925146","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}
Peatlands become one of the potential resources that could be developed as an area of rice farming to improve national food security. Agricultural cultivation in peatlands, if not managed well, will contribute to environmental destruction and land degradation, which will ultimately affect land productivity. As a first step in preparing the development of rice farming, research on the application of technology has conducted. This research included water management, which consists of: without water management or control (A0), macak-macak water management (A1) and intermittent water management (A2). Moreover, research on pesticide application was also conducted which consist of: without pesticide application or control (P0), Paraquat herbicide application at the time of tillage (P1), Fenobucarb insecticide applications every week (P2), Fenobucarb insecticide applications every two weeks (P3), Difenoconazole fungicide applications every week (P4), Difenoconazole fungicide applications every two week (P5). This study aims to determine the level of sustainability of rice farming in peatlands, and the dominant factors that influence by considering economic, social and environmental through a Multi Dimensional Scaling (MDS) approach. The analysis shows a quite sustainable level, with score for each dimension is 53.13 for the economic dimension, 69.49 for the ecological dimension and 61.79 for the social dimension. The dominant factors to be considered for the sustainability of rice farming in peatlands are changes in the level of decomposition of organic matter, farming purpose and outreach intensity.
