Giant bamboo Dendrocalamus asper is recommended in environmental and livelihood programs in the Philippines due to its various ecological, economic and social benefits. However, there are limited data on the ecology of giant bamboo litterfall production, which contributes to soil nutrient availability. Bamboo also contributed in carbon sequestration. The study was conducted within the Taganibong Watershed in Bukidnon, Philippines. Nine litterfall traps measuring 1mx1m were established within the giant bamboo stand in the study area. Results show that giant bamboo litterfall is dominated by leaves. Biological characteristics of bamboo litterfall do no not influence litterfall production but temperature, wind speed and humidity correlate with the amount of litterfall. Findings of the study further revealed that fresh giant bamboo tissue contains high carbon content and the soil in the bamboo stand has higher organic matter than the open clearing. These data indicate the role of giant bamboo in carbon sequestration and soil nutrient availability.

To determine if there is a gender difference in the resource consumption activities of students in Central Mindanao University, a Philippine state university, an ecological foot printing study was conducted in August 2014. Consumption data from 380 student respondents were gathered using a survey questionnaire. A web-based software created by the Global Footprint Network was used to convert the consumption data into its equivalent ecological footprint value. Sample size was reduced to 324 (male = 162; female = 162) through a 1:1 nearest neighbor matching without replacement method for propensity score matching. Subsequently, unpaired t-test was employed for comparing the difference in ecological footprint between the male and female student respondents. Results reveal that the students’ ecological footprint is slightly lower than the national average. Furthermore, most of their ecological footprint comes from their carbon footprint. Male respondents were found to have a significantly higher ecological footprint compared to female respondents. This implies gender difference in terms of resource consumption.
