Purpose The Philippines is among the countries vulnerable to adverse impacts of climate change. However, many local government units (LGUs) and people themselves are not aware change phenomenon do have capacity undertake appropriate adaptation measures. purpose this paper discuss strategies communities LGUs barriers recommendations enhance their adaptive capacity. Design/methodology/approach study covered five impacts. Information on extreme climatic events undertaken were gathered through...
Landscape fragmentation, the breaking up of land use type into smaller parcels, is damaging watersheds worldwide. Without addressing its causes, landscape fragmentation can permanently destroy habitats and compromise ecosystem services (ES) that a watershed provides. This paper aims to establish associations between ES by integrating science (satellite imageries analyses) local geographic knowledge (key informant interviews focus group discussions) at different time periods. Using case...
Abstract One of the main impact areas climate change (CC), and land use cover (LULCC) is hydrology watersheds, which have negative implications to water resources. Their can be indicated by changes on streamflow, quantifiable using process-based streamflow modelling baseline future scenarios. Here we include uncertainty associated risk for a robust assessment agriculture. We created model models CC LULCC “impact scenarios” that use: (1) new projections until 2070 (2) scenarios worsened...
The Baroro River Watershed, like most watersheds in the Philippines, has been experiencing widespread land use changes. With increasing interest on studies of as valuable water resources, this study attempted to assess use/land cover changes and forest fragmentation using landscape metrics. Three official maps (2003, 2010, 2015) were obtained. Cross-tabulation detection method Geographic Information System module was used detect during first period (2003-2010) second (2010-2015). tool (LFT...
Changes in the forest landscape of Mt. Makiling Forest Reserve were evaluated given three different time periods remotely sensed datasets using ISOCLUST method. The classification explicitly figured out that areas are persistent or still intact while spatially expanding coverage from area. change analysis revealed spatial distribution various land-cover categories was subjected to gain and loss based on latest previous data sets. High gains for many losses agroforestry established at certain...
This study analyzed the economic value of Calliandra calothyrsus Meissn. as a pioneer species in watershed rehabilitation using benefit-cost analysis (BCA). A cashflow was developed and 15% discount rate, net present (NPV) benefit cost ratio (BCR) were computed. Planting C. is financially feasible having positive NPV PhP202,090 ha-1 BCR 14 at 12 years rotation. Following natural order succession, benefits derived from planting species, this case calothyrsus, include reduced labor for weeding...
This study determined the impacts of landscape pattern on population density C. cebuensis within AWR, a conservation priority in Cebu, Philippines. Three land uses were identified, namely, (a) cultivated (3,399 ha/45%); (b) forestlands (3,002 ha/40%); and (c) build-up (1,050 ha/15%). Forest patches at class have irregular/complex shapes; thus forest areas AWR are more fragmented heterogeneous. Estimated was 52 53 individuals per hectare mixed natural forests. There only three predictors four...
This study examined the changes and variability in temperature rainfall patterns past 31 years (1981-2012) assessed their impacts on livelihood vulnerability of farming households City Koronadal, South Cotabato, a less studied area Mindanao located Southern Philippines. Using Intergovernmental Panel Climate Change (IPCC) framework, household was using survey data from 265 respondents, complemented with focus group discussion, field observations 2013 to 2015. Results showed significant...
