Rehabilitation Strategy

Mangrove management has been a sustainable concern in coastal wetlands for decades, especially for original near-shore wetlands and environments without mangrove forests. Although studies outlining environmental, social, and economic benefits of mangrove forests have been increasing, few studies have examined sustainability and policies for reducing or removing mangroves. This study explores the current implemented strategies pertaining to the invasion, conservation, and removal of mangroves for wetland sustainability. A total of 19 mangrove sites were sorted out to develop the main patterns and factors for the destruction or protection in estuaries on the western coast of Taiwan. For traditional wetland management, when faced with development pressure, having protected areas under certain laws is a good direction to go for mangrove sustainability. Furthermore, due to the invasion of mangroves in the mudflats, the Siangshan Wetland indicated mangrove removal can be a positive conservation case as an appropriate habitat rehabilitation strategy for benthic organisms. Under special conditions, mangrove removal provides useful insights into the sustainability of wetlands. These insights contribute to facilitating the worldwide move towards sustainable management on mangrove wetlands. The study also presents the following strategies to further reduce or remove mangroves in the coastal wetlands that contain no mangrove forests: (1) Conducting studies to evaluate the effectiveness of mangrove removal; (2) implementing policies to ensure positive influences on coastal wetlands, and (3) providing mangrove conservation education for sustainable development.

We quantified the chlorophyll a content of planktonic algae and benthic algae in periphyton on acrylic rods and in epiphyton growing on macrophytes in 24 coastal wetlands in all five Laurentian Great Lakes. Sites were selected to represent a wide range of environmental conditions ranging from nutrient-poor, clear-water marshes with abundant macrophytes to nutrient-enriched, turbid systems devoid of aquatic vegetation. Water quality and species and percent cover of submergent macrophytes were measured in each wetland. Principal components analysis (PCA) showed that total phosphorus, turbidity, and suspended solids, variables associated with human-induced degradation, were most strongly correlated with PC axis 1 (PC1), accounting for 69% of the total variation. The PC1 site score was significantly related to both periphyton and phytoplankton biomass, respectively accounting for 54 and 70% of the total variation in periphyton and phytoplankton data, whereas PC1 only accounted for 18% of the variation in epiphyton biomass. Periphytic and epiphytic biomass were negatively correlated with percent cover and species richness of submergent macrophytes, but phytoplankton biomass was not. We conclude that periphytic and planktonic chlorophyll a biomass are good indicators of human-induced water-quality degradation and recommend that both benthic and planktonic algal biomass should be routinely monitored as part of an effective wetland management program.

Over the decades the palm oil industry has managed some challenging environmental concerns regarding land transformation and degradation, increase in eutrophication, changing habitats of wildlife, pesticides runoff into inland watercourses, and probable climate change. Countries producing palm oil desire to do so in a more sustainable way that will leave the environment evergreen. Therefore this paper aims to encourage sustainable management of agro-industrial waste and its potential in making financial returns from the same waste. Hence, the study was conducted with the participation of seven local palm oil mills having different capacities and operation age. Attention was given to milling waste as they could cause serious environmental menace if unattended to properly. Milling waste includes lignocellulosic palm biomass namely the empty fruit bunches (EFB), oil palm shell (OPS), mesocarp fibres, palm oil mill effluent (POME), and palm oil mill sludge (POMS), as well as solid waste generated from the further processing of these biomass into the palm oil fuel ashes (POFA) and palm oil clinkers (POC). The opportunities available to the Malaysian palm oil industry and the financial benefits which may accrue from waste generated during palm oil production process cannot be over emphasized.

The 2303 Wetlands of International Importance distribute unevenly in different continents. Europe owns the largest number of sites, while Africa has the largest area of sites. More than half of the sites are affected by three or four impact factors (55%). The most significant impact factors are pollution (54%), biological resources use (53%), natural system modification (53%), and agriculture and aquaculture (42%). The main affected objects are land area and environment of the wetlands, occurred in 75% and 69% of the sites, respectively. The types most affected by land area occupation are river wetlands and lake wetlands, the types with the greatest impact on environment are marine/coastal wetlands and river wetlands, the type with the greatest impact on biodiversity is river wetlands, the types most affected by water resources regulation are marsh wetlands and river wetlands, and the types most affected by climate change are lake wetlands and marine/coastal wetlands. About one-third of the wetland sites have been artificially reconstructed. However, it is found that the proportions of natural wetland sites not affected or affected by only one factor are generally higher than that of wetland sites both containing natural wetlands and human-made wetlands, while the proportions of wetland sites both containing natural wetlands and human-made wetlands affected by three or four factors are generally higher than that of natural wetland sites. Wetland sites in the UK and Ireland are least affected among all countries. Wetland management plans in different regions still have large space for improvement, especially in Africa and Asia. The protection and restoration of global wetlands can be carried out in five aspects, including management and policy, monitoring, restoration, knowledge, and funding.

Indonesia is blessed with the wonderful and beautiful Lake Toba catchment area where diverse bamboo species grow and provide socio economic benefits to the Bataknese community indigenous to the region. The bamboo resource, however, hasn’t been sustainably managed due mainly to over-cutting while cultivation has been insignificant. This study aims to investigate the relevant interventions for achieving sustainable bamboo resource in this region. Data were derived from questionnaire surveys of 154 women and in-depth interviews with 65 respondents in Simalungun and Karo districts. In order to identify the cause of problem and strategies for sustainable management, a problem tree analysis was conducted. Findings of the study show that strengthening institutional framework, utilizing efficiently, enhancing initiatives on bamboo conservation and development, and promoting local stakeholders are identified as strategies for sustainable management. The basic notions are that achieving sustainable management is feasible only with stakeholders’ support, and local communities must be provided with decent incomes by efficient utilization. Furthermore, bamboo management must be supported by promoting gender equality and empower women related to their control over bamboo plantation and harvesting, market access and other decision-making opportunities on income and expenditure. The study recognizes that there is a strong relationship between decision making authority and women empowerment.

Subject The rising threat from BACRIM. Significance Organised criminal groups are now the non-state actors most frequently responsible for internal displacement of Colombians, according to a recent UN report. There is also evidence that the so-called BACRIM (criminal bands) are seeking to fill the vacuum after an eventual demobilisation of the Revolutionary Armed Forces of Colombia (FARC). The BACRIM, and Los Urabenos in particular, have expanded control over rural areas and the mining sector, posing a threat as the government seeks to attract foreign investment to boost development in a post-conflict environment. Impacts Criminal violence in cities along the western coast is already causing damage to Colombia's international image. Increased insecurity perceptions risk marring the political and economic benefits the government expects from the peace process. Criminal groups such as Los Urabenos will benefit from the vacuum left by the FARC if a peace treaty is signed later this year.

Rural tourism is seen as a potential sector in promoting country to the world and at the same time generates incomes to local communities. However, due to the lucrative economic benefits, tourism destination’s sustainability and quality of services is often being ignored. Thus, this study highlights the importance of sustainable management and destination marketing efforts in rural tourism destinations with identified significant contributively factors from local communities’ perspective. A total of 168 respondents comprising of local communities from <em>Kampung Telaga Air</em> and <em>Kampung Semadang</em>, Kuching, Sarawak took part voluntarily in this study. To assess the developed model, SmartPLS 2.0 (M3) is applied based on path modelling and bootstrapping. Interestingly, the findings revealed that local communities believed factors like climate change, carrying capacity of a destination, and environmental education are significantly affect both tourism destination sustainable management and destination marketing efforts. Furthermore, community support is also found to be important too for tourism destination marketing efforts. Surprisingly, community support was found no relations with destination sustainable management from local communities’ point of view. This study further discussed on the implications of the findings, limitations, and direction for future research.

Mangrove forests are type of salt tolerant vegetations, living in tidal zones in tropical and subtropical coastal areas with unique ecosystem that have a strategic function as a connector and counterweight of terrestrial and marine ecosystems. These forests as a whole is considered a productive ecosystem and it have complex functions, such as physical functions, biological functions and socio-economic functions. Fishery resources of mangrove forests are very productive, both quantitatively and qualitatively, because the mangrove forests act as the natural habitat (spawning, nursery and feeding grounds) for various species of fish, shrimps and crabs, as well as a source of germplasm and genetic pool. Mangrove forests also provide valuable ecosystem services to coastal communities, tourist attractions, nature conservation, education and research. However, these ecosystems are fragile because it is very sensitive to environmental changes, usually because anthropogenic influences; therefore, it is difficult to be restored. In addition, these ecosystems are so openly accessible that easily exploited by humans; this can reduce its quality and quantity. Local communities who use mangrove forests and their resources may have considerable botanical and ecological knowledge about their forests. Silvofishery techniques in aquaculture are very suitable for community-based mangrove forests conservation efforts. Silvofishery is an integrated model that considers both economically benefit and conservation.
