Climate change is already happening and affecting many places causing huge problems to coastal ecosystems. Vulnerability and disaster assessment and mapping in coastal areas are essential tasks and undertakings for coastal disaster risk management. The objectives of this study were to assess the climate change vulnerability and disaster risks in the four municipalities (Sta. Cruz, Candelaria, Masinloc and Palauig) of Zambales and to determine the climate change community-based adaptation (CBA) and ecosystem-based adaptation (EBA) strategies. Remote sensing, GIS, secondary data gathering and key informant interview were used to assess vulnerability and disaster risks and mapping in the four municipalities. Survey questionnaire, focus group discussion and key informant interview were utilized in gathering data for the determination of climate change adaptation strategies. Using remote sensing technology, it was revealed that coastline changes have occurred in the shorelines of the four coastal municipalities after a decade. Sea level rise happened in Sta. Cruz and Masinloc, Zambales while there was build-up of soil in the coastline of Candelaria and Palauig, Zambales. Twelve hazard maps, 12 vulnerability maps and 12 disaster risk maps were generated for the three major disasters (flood, landslide, storm surge) in the four coastal municipalities. Based on the flood vulnerability and disaster risk assessment, the municipality of Palauig was found to be the most prone to flooding while the municipality of Candelaria was found to be the most vulnerable to landslide compared to other municipalities. All coastal barangays in the four municipalities were susceptible to storm surge. The four coastal municipalities were conducting community-based adaptation (CBA) and ecosystem-based adaptation (EBA) approaches in order to protect their coastal resources from the damaging impacts of climate change and improve the resilience of their local communities.展开更多

Thus, implementation of climate change adaptation strategies is vital to counter the effects of climate change. It is in this context that this study was undertaken to analyze the need or urgency to adopt community and ecosystem-based adaptation strategies among selected coastal barangays (villages) of Masinloc, Zambales, Philippines. Various methods of data collection were utilized such as secondary data collection, primary data collection through household survey, key informant interviews, and focus group. Results of the study indicate that in terms of community-based adaptation strategies, all of the seven barangays in Masinloc have moderate necessity. However, only Barangays Bani and Collat have high adaptation capacity in terms of infrastructure and disaster preparedness. The execution of several community-based adaptation strategies helps these barangays to respond immediately and appropriately to the moderate risk posed by floods and storm surges. On the other hand, in terms of ecosystem-based adaptation strategies, all of the seven barangays have moderate necessity which implies that they have moderate vulnerability and risk to flood and storm surge but have high adaptation capacity in terms of the conservation and protection of coastal resources (mangroves and sea grasses). The barangays implemented the necessary ecosystem-based adaptation mechanisms that they might need in the future. This only means that when they are faced with disaster, the local communities are prepared to respond appropriately and to cope up with the effects of extreme weather events which lead to floods and storm surge. Even though most of the ecosystem-based adaptation strategies are conducted by the seven barangays, there are several community-based adaptation strategies that are still lacking which will protect them from the effect of floods and storm surges. Hence, carrying out the missing adaptation strategies, both community-based and ecosystem-based, will help in improving the adaptive capacity of the affected barangays and will help them become more resilient to the amplified effects of climate change.展开更多

Tropical cyclones have a high incidence of passing through the Philippine islands during the months of September to November with an average time overland at 11 hours north of 14.5<span style="white-space:nowrap;">°</span> contrasted to 20 hours south of 14.5<span style="white-space:nowrap;">°</span>. Due to the frequent occurrence of typhoons and tropical cyclones in this country, most of the provinces of the Philippines experience flood-related disasters that affect the people, their livelihood and many infrastructures. It is deemed necessary for the Philippines to come up with strategies to prevent further damage to its people and their properties. In this study, through the use of important parameters such as earth observations, Light Detection and Ranging (LiDAR) and Geographic Information System (GIS), assessment of buildings in Dagupan, the Philippines with the possibility of being affected by floods during different typhoon scenarios was done. GIS overlay analysis of the CLSU Phil-LiDAR 1 Project outputs, the 3D building GIS database, and flood hazard maps was done for the assessment. One (1) meter resolution LiDAR Digital Elevation Models (DEMs), geo-tagged video captured data and high-resolution images in Google Earth were used for processing and analysis to produce a 3D building GIS database. HEC HMS and HEC RAS were used to develop flood models that were used to produce flood hazard maps with different hazard levels. The results of this study were the series of flood exposure maps and vulnerability maps with statistics at different rainfall scenarios. Moreover, the buildings that will be affected by flood in the area were quantified and these were categorized according to their type. It was observed that as the rainfall return period increases, the number of buildings predicted to be exposed and vulnerable to flood also increases. The houses, business establishments, government offices, hospitals and other building types that are at risk of being affected by the flood were counted. Through analysis, it was predicted that there is a higher risk of building exposure and vulnerability during the 100-year rainfall return period. Out of the 71,884 buildings extracted from the area, a predicted 69,214 buildings will be exposed to flood during the 100-year rainfall return period, 59,137 buildings, 9253 buildings, 824 buildings at low, medium and high flood hazard level, respectively. Moreover, a total of 9297 buildings are foreseen to be vulnerable to flood, 4614 buildings, 4368 buildings, 315 buildings at low, medium and high flood hazard levels, respectively. The maps produced through the study are a valuable asset for the development and preparedness of the community in the Dagupan floodplain. Warnings and other information on evacuation measures will be easier to disseminate through the use of the produced maps in this study.展开更多

The objectives of the study were to assess climate change impacts and vulnerability of Bongabon, Gabaldon and Cabanatuan City, Nueva Ecija;to assess the vulnerability and suitability of growing various crops, goats and chicken;to generate vulnerability and suitability maps;and to validate the maps produced. A comprehensive scoping, profiling, vulnerability assessment and crop, chicken and goat suitability assessment of the municipalities and agroecosystems of the study sites was done. Generation and validation of the vulnerability and suitability maps were also conducted. Results revealed that Bongabon obtained moderate vulnerability to floods and typhoon while low vulnerability to drought and soil erosion. Gabaldon had moderate vulnerability to floods, soil erosion and drought while low vulnerability to typhoon. Cabanatuan City attained moderate vulnerability to floods and drought while low vulnerability to typhoon. There were four crops suitable to grow in the current condition with flood and landslide hazards and in the two projected future scenarios (RCP 4.5 with good conditions and RCP 8.5 with the worst conditions). Only three crops are highly suitable to grow in Gabaldon for the future conditions while in Cabanatuan City four crops are very suitable for the three situations. Native chicken and goats are highly suitable to raise in the three study sites for the three conditions. There were 16 vulnerability maps developed and generated in Bongabon, 16 in Gabaldon and only 12 in Cabanatuan City. Furthermore, 21 crop, chicken and goat suitability maps were produced in Bongabon, 27 maps in Gabaldon and 21 maps in Cabanatuan City. Overall, validation of the maps in the study sites had high accuracy.展开更多

The rapid build-up of toxic pollutants (metals, radionuclide, and organic contaminants in soil, surface water, and ground water) not only affects natural resources, but also causes major strains on ecosystems. Interest in phytoremediation as a method to solve environmental contamination has been growing rapidly in recent years. This green technology that involved “tolerant plants” has been utilized to clean up soil and ground water from heavy metals and other toxic organic compounds. Phytoremediation involves growing plants in a contaminated matrix to remove environmental contaminants by facilitating sequestration and/or degradation (detoxification) of the pollutants. Plants are unique organisms equipped with remarkable metabolic and absorption capabilities, as well as transport systems that can take up nutrients or contaminants selectively from the growth matrix, soil or water. As extensive as these benefits are, the costs of using plants along with other concerns like climatic restrictions that may limit growing of plants and slow speed in comparison with conventional methods (i.e., physical and chemical treatment) for bioremediation must be considered carefully. While the benefits of using phytoremediation to restore balance to a stressed environment seem to far outweigh the cost, the largest barrier to the advancement of phytoremediation could be the public opposition. The long-term implication of green plant technology in removing or sequestering environmental contaminations must be addressed thoroughly. As with all new technology, it is important to proceed with caution.展开更多

Some of the less studied areas in the Philippines are the river systems in the Cordillera which are equally important as that of the other freshwater systems in the country. Amburayan River in Kapangan, Benguet is one of the rivers in the said region. Thus assessment study of the diversity of macro aquatic species was conducted to provide a baseline data in the formulation of resource management strategies and polices. By using a mixture of qualitative and quantitative research methods, the study determined and identified the presence of macro species in the study area. It applied the National Stock Assessment Program (NSAP) procedures in the gathering of samples while identification and determination of fish stocks were done by morphometric analysis of the catch with the help of available references and assistance of experts. This is later verified through submission of samples to the National Fisheries Research Development Institute (NFRDI) as part of the NSAP areas for DNA analysis. The measurement of the impacts of human activities to the river systems was done using the checklist method by Smith and Smith. The study found that there is low biodiversity of macro aquatic species in the area because of the presence of introduced species, illegal fishing practices, quarrying and mining activities. There are also no indigenous or traditional management measures conducted to conserve the river ecosystem biodiversity. The study recommended that similar study be done in other areas of the river and that the government agencies to undertake fisheries programs which would regulate the exploitation and utilization and allow regeneration of macro aquatic species in the river system.展开更多

The purpose of the study was to find out how local communities perceived about IEC materials on community-based adaptation techniques and ecosystem-based approaches to combating climate change. It also examined the relationship be-tween respondents’ sociodemographic characteristics and the IEC materials’ attributes. Forty-two (42) coastal barangays in Zambales yielded 640 responses using survey questionnaires. Data analysis included frequency, percentage, and correlation. IEC materials were effective in comprehension, relevance, content, visual appeal, acceptance, and impact. Respondents were able to swiftly understand simple statements concerning climate change. Respondents were significantly impacted by attractiveness, visually appealing and recognizable images about adaptation and mitigation strategies for climate change. Municipalities were associated with practically all IEC material attributes. Education and respondent type influenced some IEC material characteristics. Coastal municipalities had different views on IEC material attributes. Because of IEC materials’ effectiveness, coastal communities are more inspired and motivated to take climate action. IEC materials give local populations useful knowledge about climate change that they may apply even in the absence of formal education.展开更多

文摘Climate change will impact coastal ecosystems,threatening subsistence fisheries including those in mangrove forests.Despite their global contributions and roles in nutrition and cultural identity,mangrove subsistence fisheries are poorly studied.Here,we offer a foundation for improving the management of mangrove subsistence fisheries to deal with the impending effects of climate change.This multidisciplinary review—drawing on organismal biology,ecology,fisheries,and social science—focuses on the climate impacts relevant to mangrove ecosystems:heat waves,low-category,and high-category typhoons.First,we provide an overview of the mangroves,their harvestable stocks(fish,crustaceans,molluscs),and the fishers,offering an understanding of how they may be affected by relevant environmental variables;i.e.,shifts in temperature,salinity,oxygen,flooding,and sediments.Then,we examine the potential effects of climate change on mangrove stocks and fishers,indicating the scope of impending changes.By combining the above information,we develop a simple model that forecasts the number of“fishing-days”lost by fishers due to climate change over the next decade(between 11 and 21 days will be lost per year per fisher).This indicates which aspects of climate change will have the greatest impacts on stocks and fishers.We found that high-category typhoons had more impacts than heat waves,which in turn had a greater impact than low-category typhoons).Finally,recognising gaps in our knowledge and understanding,we offer recommendations for approaches for future work to improve our predictions.
