Level of awareness and practices on solid waste management (SWM) among college students
Perla R Bautista
The earth suffers from many environmental problems which need to be tackled at the individual level, requiring individuals to develop that awareness that will guide them to become environmentally supportive. The study endeavored to determine the significant relationship between the level of awareness and practices among Filipino college students on solid waste management. It employed a descriptive correlational research design with 150 randomly sampled students. Using the adopted standardized survey instrument surfacing the level of awareness of solid waste management of students and their practices. Gathered data were analyzed and interpreted using descriptive and inferential statistics. The findings of the study showed that the students are aware of solid waste management. Most of them were aware of the policies and management of SWM but relatively not aware of their roles as students in the implementation of SWM. The students also have good practices in solid waste management in terms of properly disposing of, recycling, and reusing but moderately practice proper segregation and reducing. Results of the inferential statistics revealed that the level of awareness of the students influenced their practices on proper segregation, reduction, and recycling but no influence to their practices on solid waste management in terms of reuse and disposal. Present findings can be a basis for policy development on SWM implementation at the campus level. Source J. Bio. Env. Sci. 14(1), 131-138, January 2019.
Above-ground biomass and carbon stock estimation of Arroceros Forest Park “The Manila’s Last Lung” using geographic information system (GIS)

In an area where urbanization is rapidly growing, carbon is slowly sequestered which clogs the ozone layer. With forest biomass, carbon is easily sequestered and stored by trees. This research focuses on the potential carbon storage of the Arroceros Forest Park, one of the last lungs of the metropolis located in the heart of the National Capital Region, Manila, Philippines. Trees with ≥10 cm diameter at breast height (DBH) were inventoried, from two (2) hectare areas of the site. These trees were used in the estimation of the biomass and carbon stock. The Power-Fit Equation from Banaticla (insert year), = 0.342 (DBH (exp (0.73))) was used in the study. Results showed that Swietenia macrophylla dominated the park. The species with the highest contribution of biomass and carbon is the Swietenia macrophylla with a value of 149.55t/ha. The carbon formed from this was 45%, and the estimated carbon stock present is 30.59Ct/ha. Total Above-ground biomass and carbon stock in the forest park is estimated at 640.21t/ha, and 130.95Ct/ha, respectively. Provided the carbon stock estimate, this could give more importance to Arroceros Forest Park in carbon sequestration. The site must be protected and enhanced to promote the important role of green spaces in Metro Manila.
