Today’s ecological crises reveal the increasing awareness that the world is threatened not only by poverty, conflicts and injustices but also by lack of respect for nature. Through the tri-fold participatory and partnership approach, the Sorsogon State College (SSC), together with the LGU of Magallanes and its community beneficiaries collaborated in empowering coastal communities and helped address various concerns affecting them. In a purposive sampling technique, a total of 57 respondents composed of the key informants in the coastal communities and line agency heads gathered for this research cum extension project. The descriptive–evaluative method was employed adopting qualitative research technique. In evaluating the risk scenarios, a retroactive analysis was utilized, the results clearly illustrated the sequence of outcomes of two dreadful disasters in the Magallanes. The assessment of the pressures disclosed various vulnerabilities of the town to hazards. The established Hyogo-Framework of Action (HFA) had strengthened the capacities of the municipality to effectively response and recover in future disaster. In conclusion, ecological crisis is the responsibility of everyone since irresponsible human activities were found to have brought major physical, economic and social consequences to the community. Stewardship of resources should be encouraged through outreach/volunteer participation to a safer healthy environment.

The Guimaras oil spill was a massive oil spill at the Guimaras Strait, the Philippines. It was dubbed as the worst oil spill ever in the Philippines. The oil tanker M/T Solar 1, carrying more than two million liters of bunker fuel, sank on August 11, 2006 at the Guimaras Strait off the coast of the Guimaras and Negros Occidental provinces, causing some 500,000 liters of oil to pour into the strait. It has been said that the recent oil spill has adversely affected marine sanctuaries and mangrove reserves in three out of five municipalities in Guimaras Island and reached the shores of Iloilo and Negros Occidental. The oil spill occurred in the Visayas Sea which is considered a rich fishing ground that supplies most of the fisheries demand for the entire country. This study was therefore conducted to determine what life is among the Guimaras fisher folks after the oil spill in 2006. Interviews were conducted to generate the data needed in this investigation. Results showed that ‘life was not the same before and after the oil spill. Fish catch and sea shells became few and children are now afraid to bathe in the waters for fear of the oil spill’s effects. Development of milkfish fish cage, handicrafts, and food preservation were top most livelihood activities resorted to by the fisher folks after the oil spill. Budget inclusion, research and other trainings were part of the LGU and International interventions that were done after the oil spill.

Industrialization and the unhealthy environmental life of people along river communities have threatened the water quality of coastal waters. This research assesses the water quality of selected areas of Macajalar Bay measured using the following parameters: 1) physical water quality in terms of temperature, salinity and color; 2) chemical water quality in terms of pH, biochemical oxygen demand (BOD), salinity, dissolved oxygen (DO) and total suspended solids (TSS); and 3) biological water quality in terms of the total coliform. This study used the descriptive research design. It described the current quality of water of Macajalar Bay. Also, it carried a comparative aspect when the fragmental characteristics of the water and the quality criteria of the DENR and seaweed farming were considered. The samples were collected during the 4th quarter of 2008 and 1st quarter of 2009. The sampling was done once in every quarter of the year particularly in October (2008) and January (2009). Water samples were collected immediately using sterilized bottles/plastic containers and brought to the Department of Science & Technology (DOST) Laboratory for analysis. Except for the total Coliform, all the physical and chemical characteristics of water across all stations were within the Class B standard of the DENR and seaweed farming. Overall, the Macajalar Bay falls under Class “B” indicating that the water’s quality has remained acceptable.

Mangroves play an important role in the dynamics of the marine ecosystem. This descriptive study determined diversity of mangrove species of Calatagan Mangrove Forest Conservation Park- a Marine Protected Area located at the community of Quilitisan and of a mangrove rehabilitation area located at the community of Balibago, Calatagan, Batangas. A total of 8 quadrats measuring 10m x 10m were laid along the low intertidal zone and mid- intertidal zones of the study sites. Data on abundance, frequency and density parameters were gathered from these quadrats. There were 9 species of mangroves found in the mangrove conservation park while there were 7 species found in the rehabilitation area. The species that are common to the two study sites include A. marina, R. stylosa R. mucronata, R. apiculata, S. alba, and S. caseolaris, The species that are distinct in the community of Quilitisan include A. corniculatum, C. tagal and C. decandra. The mangrove species B. cylindrica was sampled only in the community of Balibago. The mangroves in Quilitisan have average GBH of 21.69 cm; average height of 3.89 m; average crown of 2. 16m; and average DBH of 6.90cm. The mangroves in Balibago have average GBH of 23 cm; average height of 5.62 m; average crown of 1. 76m; and average DBH of 6.90cm. The mangrove forest in Quilitisan, though with higher species richness, is found to have a relatively lower diversity index of 1.05 than that of Balibago which is 1.21 using Shannon- Weiner Diversity Index.

Mangrove ecosystem plays significant role in marine ecology. The study focused on the status of mangrove ecosystem at Buenavista, Looc, Romblon. The method used was descriptive survey, and the data needed were gathered using the transect and quadrat method. The statistical tools used in this study were relative measurement, Analysis of Variance (ANOVA) and Duncan Multiple Range Test (DMRT). The result of the study revealed that preserving the mangrove ecosystem would help the residents determine the benefits given by mangrove species in that area and its importance to marine ecosystem, the volunteers who implement the rules would benefit and also the residents living near the coastal area, the mangrove ecosystem of Buenavista was still in good condition. Analysis of Variance showed that there is significant difference on the four (4) mangrove species in terms of: frequency of occurrence, relative frequency, relative density, relative dominance and importance value. Likewise, there is no significant difference on the four (4) mangrove species in terms of: quadrat of occurrence, number of trees, basal area, percent crown cover, average height and regeneration.

The mangal community in Malhiao, Badian, Cebu was assessed in terms of physicochemical properties, detailed listing of its mangrove-associated flora and fauna and indices of diversity. A Transect Line Plot (TLP) method was employed to obtain data on mangrove community structure. Assessment revealed that there were 12 true mangrove species belonging to 6 families (H=1.78), where R. stylosa was the densest species (51.75%) and had the highest frequency value (30.48%) while N. fruticans was the most dominant (39.13%). Of all species, R. stylosa had the highest importance value (116.13%). Mangrove-associated fauna in Malhiao include 3 species of birds where Egretta is migratory, 4 species of fishes, 4 species of sponges, a species of cnidarian, 9 species of echinoderms, 3 species of insects, 2 species of spiders, 6 species of mollusks, 4 species of crustaceans and a species of mangrove skink. Mangrove-associated flora overlapped with mangroves in the seaward zone and include 5 seagrass species and 3 macroalgal species. Mangroves in Malhiao are not declining, and there is a high regeneration potential. There is evidence of illegal hunting and frequent gleaning of intertidal mollusks which is a growing threat to biodiversity.
