Mangrove community in Tial is potential and roles importantly for aquatic organism, local community and especially for coastal waters abrasion control in Tial. Due to the high rate abrasion in Tial, mangrove  community should be maintained and conserved. Therefore, the research is done in order to analyze mangrove composition, its potency and its condition on the coast of Tial.  Belt transect and hemispherical photography method are used to collect data by determining the observation station.  Three plots of  10 x 10 meter squares are placed in every observation station without space in between each plot where the ≥ 15 cm of circumference trees measuring is done and canopy photo of breast  height are taken up above perpendicularly. Microsoft Excel and Image J software are used to analyze collected data. The result shows that there are 9 species of mangrove from 7 genera and 5 families found in the coast of Tial. Sonneratia alba and Aegiceras floridum dominates the community where A. floriduim with 13 ind/100 m2 is the highest density species, while the frequency of occurrence and the highest dominance species is S. alba with the rate 0,67 and 2298,75 cm2/100 m2. Overall mangrove vegetation health is categorized good with a high density and in a medium canopy coverage.   ABSTRAK: Komunitas mangrove merupakan komunitas yang cukup potensial dan memiliki peranan penting bagi organisme perairan sekitar dan bagi masyarakat setempat, terutama dalam mengendalikan abrasi pada pesisir pantai Tial. Laju abrasi yang terjadi pada pesisir pantai Negeri Tial cukup tinggi, sehingga keberadaan mangrove pada perairan tersebut perlu dijaga dan dilestarikan. Tujuan dari penelitian ini adalah untuk mengetahui komposisi, Potensi dan kondisi mangrove di perairan pantai Tial. Metode yang digunakan yaitu metode transek sabuk dan hemisperichal photography.

Girl-child marriages in the developing countries of the world have caused a lot of suffering on the girl-children. According to Giddens (2009) issues of poverty, cultural practices, and political instability and gender inequalities have been noted as some of the major causes of girl-child marriages in developing countries. The situation has caused great concern to the communities of the global village because of the serious damages on the victims. Gage (2011) states that the status quo was exacerbated by the historical gender inequalities that continue to exist within families systems and place the girl-child an inferior citizen in her country. The girl-child remained vulnerable and segregated particularly, in educational advancement which is the key to self-empowerment, knowledge and skills development because of the high rate of girl-child marriage in the area. It appears there is little significant research on the matter in the developing countries. In order to establish some strategies to promote the girl-child’s life-skills a study was conducted in Samanga ‘A’ in Honde Valley in Manicaland Province- Zimbabwe. From a population of 1500 a sample size of 100 participants was selected using the cluster, systematic and purposive techniques because of their appropriateness to the two paradigms (Punch, 2009). Cluster technique was employed because the participants lived in different kraal-heads. The systematic technique was engaged because the participants were selected from every tenth household in each of the five kraal-heads. The purposive technique was used to select the influential participants such as local community leaders and the victims of early girl-child marriage. Marshall and Roseman (2006) support that purposive technique in qualitative study because the participants are powerful sources of information that is needed. Both qualitative and the quantitative paradigms were used in the study because some aspects of the study required simple response, while some of the questions demanded the participants’ in-depth knowledge on the problem (Newman, 2010). A case study methodology was adopted because of its ability to focus on a specific issue in a concerned area (Croll, 2010). Data were collected through the use of direct observation, questionnaire with both open and closed ended questions and interviews. The data were descriptively analysed. The research revealed that the prevalence of early girl-child marriage was perpetuated by the society’s cultural deprivation ideology which has since seen the girl-child discriminated in her efforts for self - empowerment through education. The study recommended that there is need for the government to enforce and implement gender-sensitive policies which aim at protecting the girl-child in-order to enhance economic, social, cultural and political transformation for sustainable development in the community.

The footbridges in rural areas have been crucial as the only mean to overcome the rural isolation and allow breaking the cycle of poverty by providing access to such development facilities like education opportunities, markets, medical clinics and other basic services. In Rwanda, under collaboration with Engineers without Borders from German, and International Non-Government Organization Bridge to Prosperity (B2P, some footbridges are already built. In line with the agreement with B2P around 355 bridges are also planned in 5 years. The key challenge is to optimally allocate resources in order to maintain this number of bridges, especially under the current financial constraints. The purpose of this paper was to investigate and propose a pedestrian footbridge management system for Rwanda (PFBMS) which should allow the efficient bridge management, through the analysis of condition data, determination of the ranking and priority of bridge maintenance activities, as well as evaluation of the alternatives of preservation or replacement. The methodology comprises of the use of interview and discussions with district engineers in charge of bridge management, local community using the constructed footbridges as well as bridge builders from B2P. Microsoft Excel analysis tool has been used to developing the deterioration model, and therefore the PFBM was proposed. It is concluded that this system can accurately predict optimal maintenance planning as well as bridge rating.

Understanding the dietary habits of sympatric apex carnivores advances our knowledge of ecological processes and aids their conservation. We compared the diets of the sympatric Snow Leopard Panthera uncia and Grey Wolf Canis lupus using standard micro-histological analyses of scats collected from the western complex of Nepal Himalaya. Our study revealed one of the highest recorded contributions of livestock to the diet of top predators (55% for Grey Wolf and 39% for Snow Leopard) and high dietary overlap (0.82) indicating potential exploitative or interference competition. Their diet composition, however, varied significantly based on their consumption of wild and domestic prey. Limitation in data precludes predicting direction and outcome of inter-specific interactions between these predators. Our findings suggest a high rate of negative interaction with humans in the region and plausibly retaliatory killings of these imperilled predators. To ensure the sustained survival of these two apex carnivores, conservation measures should enhance populations of their wild prey species while reducing livestock losses of the local community through preventive and mitigative interventions.

A high rate of vegetation clearing around the upper stream of Kali Bekasi watershed currently causes various environmental problems, such as floods. The impacts occur predominantly in downstream area, mostly affecting cities, due to a disruption of the ecosystem in the upper stream. The main function of the upper stream to humans is acting as a buffer to protect downstream areas from flooding, run-off, as well as biodiversity protection. To achieve this, many varieties of plant are grown including bamboo plantations, which serve as a buffer plants on critical land especially with steep contours. In this study we aim to provide a better understanding of the effectiveness of different bamboo stands buffering to improve information for making management recommendation. We examine different points along the stream by mapping bamboo distribution, analyzing bamboo and non-bamboo (tree) stands diversity and biomass, and provide recommendations for bamboo management based on combining our findings with local ecological knowledge. We implemented image classification analysis for classifying bamboo and non-bamboo land use cover. We also measured bamboo and non-bamboo diversity by using Shannon’s-Wienner diversity index. Our results showed that bamboo occupies approximately 5,360.89 ha or 11.39% of total area with six bamboo species. The highest bamboo diversity index was in the upper part of the Kali Bekasi watershed (0.62). In contrary, the highest bamboo biomass index was found in the lower part of the upper stream of Kali Bekasi watershed (98.96 ton ha-1). We also discovered about 29 species of tree (230 trees) and 27 above-ground plant species in the surveyed area. As a result of our findings, we propose a shift towards bamboo agroforestry management in a mixed garden of talun form, where the community implement their local knowledge on bamboo cultivation and management to maintain the bamboo. This option could improve cooperation among farmers and the local community in order to conserve bamboo and tree species diversity in harmony to local wisdom.

ABSTRAK: Ekosistem mangrove adalah komunitas tumbuhan tropis yang berada di daerah tepi pantai yang memiliki kemampuan adaptasi pada perairan asin di wilayah intertidal yang dipengaruhi oleh pasang surut air laut. Struktur komunitas mangrove merupakan salah satu parameter dalam menentukan kondisi mangrove. Kawasan ekosistem mangrove yang memiliki karakteristik dinamis komposisi jenis mangrove terdapat di Segara Anakan. Akan tetapi memiliki penurunan luasan hutan mangrove. Hal ini adanya beragam faktor kondisi lingkungan di Segara Anakan, sehingga menyebabkan variabilitas mangrove wilayah Segara Anakan berbeda. Namun kondisi terkini belum banyak dilakukan dalam suatu penelitian sehingga dibutuhkan informasi ilmiah terkini untuk mengetahui komposisi jenis mangrove. Untuk mengatasi hal tersebut maka dilakukan penelitian struktur komunitas untuk mengetahui kondisi ekologi mangrove di Segara Anakan. Tujuan penelitian ini adalah menggambarkan kondisi struktur komunitas mangrove di muara timur Segara Anakan. Lokasi penelitian berada di muara sungai bagian Timur (Sungai Donan). Metode yang digunakan dalam penelitian ini adalah metode deskriptif. Penentuan titik pengambilan data atau sampel di setiap lokasi dilakukan dengan teknik purposive sampling. Selain itu, digunakan teknik transek kuadrat 10x10 m dan Hemispherical Photography. Hasil penelitian menunjukkan kerapatan pohon sebesar 90,6 /ha. Kerapatan sapling rata-rata bernilai 1023 /ha. Kerapatan seedling bernilai 1746 /ha di Muara Timur. Tutupan kanopi komunitas mangrove memiliki persentase kurang dari 75%. Tinggi dan diameter pohon didapatkan sebesar 5,97 m dan 3,1 cm. Spesies mangrove yang ditemukan di dalam plot berjumlah 10 spesies mangrove yaitu Rhizophora apiculata, Bruguiera gymnorrhiza, Aegiceras corniculatum, Avicennia marina, Avicennia alba, Ceriops tagal, Ceriops decandra, Sonneratia caseolaris, Sonneratia alba, Scyphiphora hydrophyllacea, Xylocarpus moluccensis, Xylocarpus granatum, Talipariti tiliaceum, dan Nypa fruticans. ABSTRACT: Mangrove ecosystems are communities of tropical plants located on the coast that have the ability to adapt to salty waters in intertidal areas which are affected by tides. Mangrove community structure is one of the parameters in determining mangrove condition. Mangrove ecosystem areas that have dynamic characteristics of mangrove species composition are found in Segara Anakan. However, it has decreased the area of mangrove forests. This is because of various environmental conditions in Segara Anakan, causing variability of mangroves in the Segara Anakan area to be different. However, recent conditions have not been carried out in many studies, so the latest scientific information is needed to determine the species composition of mangroves. To overcome this, a community structure research was conducted to determine the ecological conditions of mangroves in Segara Anakan. The purpose of this study was to describe the condition of the mangrove community structure in the eastern estuary of Segara Anakan. The research location is in the mouth of the eastern river (Donan River). The method used in this research is descriptive method. Determination of data collection points or samples at each location was done by using purposive sampling technique. In addition, the 10x10 m quadratic transect technique and Hemispherical Photography were used. The results showed the tree density was 90.6 ind/ha. Saplingaveraged 1023 ind/ha. The density seedling is 1746 ind/ha in Muara Timur. The canopy cover of the mangrove community has a percentage of less than 75%. The tree height and diameter were 5.97 m and 3.1 cm respectively. There are 10 mangrove species found in the plot, namely Rhizophora apiculata, Bruguiera gymnorrhiza, Aegiceras corniculatum, Avicennia marina, Avicennia alba, Ceriops tagal, Ceriops decandra, Sonneratia caseolaris, Sonneratia alba, Scyphiphora hydrophyllacea, Xylocarpus moluccensis, Xylocarpus granatum, Talipariti tiliaceum, and Nypa fruticans.

 Production and decomposition of mangrove litter could contribute organic matter and nutrients to the coastal waters. This study was to estimate the extent to which the rehabilitated mangrove of Rhizophora mucronata and Sonneratia alba contribute organic matter. This study was conducted from November 2015 to January 2016. Litter traps were used to collect the litter production and litterbags to measure decomposition rates. The results showed that the average of litter production for Sonneratia alba and Rhizophora mucronata was 4,38 g.m-2.day-1 and 3,61 g.m-2.day-1, respectively. However, Sonneratia alba apparently showed higher decay rates compare with Rhizophora mucronata. Nutrients element (N and P) released were 321,2 kg.ha-1.years-1 and 47,45 kg.ha-1.years-1 for Sonneratia alba; and 131,4 kg.ha-1.years-1 and 13,14 kg.ha-1.years-1 for Rhizophora mucronata. Overall, this study indicated that the mangrove rehabilitation in the area study contributed insignificantly carbon restocking the affected area, although it was able to provide ecological functions of this mangrove ecosystem.
