Abstract This paper investigated the vulnerability of the agriculture sector and rural agriculture livelihoods in the Bicol River Basin (BRB) of the Philippines to projected changes in climate. The geographical characteristics of the BRB feature eight major sub-basins or watersheds consisting of Libmanan-Pulantuna, Ragay Hills, Thiris, Naga-Yabo, Pawili River, Waras-Lalo, Naporog, and Quinali. The study applied the combination of the participatory tools and the Climate Risk Vulnerability Assessment (CRVA) framework to gather information on local climate vulnerabilities and contexts. Briefly, the CRVA employed geospatial modeling and utilized a number of indicators that are presumed to affect vulnerability including exposure, sensitivity, and adaptive capacity which were aggregated to provide an index of vulnerability. This enabled us to identify areas of exposure and vulnerability and pointed areas of greatest need for strengthened adaptive capacity and risk management. Our findings revealed that vulnerability in the BRB was perceived to be relatively prevalent and that typhoons, flooding, and drought were identified to contribute significant impacts to the rural livelihood. Furthermore, our findings in the CRVA suggested significant regional differences in vulnerability in the BRB. Majority of the towns in the north and central portions of the BRB will largely experience increased vulnerability, particularly, in the Thiris sub-basin including some parts of Ragay Hills, Waras-Lalo, and the northwestern Libmanan-Pulantuna sub-basins. On the contrary, the entire Quinali region on the south revealed to have the lowest vulnerability index. The clear policy implication of these accounts will be on how to mobilize developmental thrusts in both areas of disaster risk reduction and climate change adaptation at the sub-national level to reinforce local-based climate priority setting in adaptation interventions and policies.

Anthropogenic caused environmental changes coupled with rapid population growth are altering the Earth’s biota at unprecedented rates, posing an alarming threat to the long-term persistence of many species of both animals and plants and so, a science-based prioritisation encompassing multiple dimensions is necessary. In the over 7000 Islands of the Philippine archipelago, a large proportion of bat diversity constitute the mammalian fauna of the country, which performs various ecological functions. However, many species are in need of high conservation attention yet the level and understanding of their vulnerability remain anecdotal. In this study, we aim to determine the vulnerability of Philippine bat species from different threats, which is important to establish effective conservation decision making and prioritisation in the future. We found that habitat loss and direct human-driven (e.g., hunting) is the main threat to more than half of the Philippine bat species. As expected, threatened and endemic species are facing higher levels of vulnerability with the strong positive relationship between Species Vulnerability Index (SVI) and Absolute Number of Threats. However, a weak relationship between Species-Research Effort Allocation (SREA) and SVI indicating a strong disparity in efforts and priorities among species. Given the high species richness, endemism, vulnerabilities, and disparity in efforts, the Philippine is indeed a conservation hotspot for bat biodiversity. We suggest that priorities should holistically consider multiple facets in knowledge paucity, levels of threats and species vulnerability for effective conservation process. Eyeing carefully on the emerging and unknown threats, increasing conservation education, and forging equitable partnerships and capacity building to bolster bat conservation in the Philippines.

Abstract This paper investigated the vulnerability of the agriculture sector and rural agri-fishery livelihoods in the Bicol River Basin (BRB) in the Philippines to projected changes in climate. The geographical characteristics of the BRB features eight major sub-basins or watersheds consisting of Libmanan-Pulantuna, Ragay Hills, Thiris, Naga-Yabo, Pawili River, Waras-Lalo, Naporog, and Quinali. The study adopted the Climate Risk Vulnerability Assessment (CRVA) which employed geospatial modelling through the use of geographic information systems (GIS) data, briefly, a number of indicators which are presumed to affect vulnerability were used including exposure, sensitivity, and adaptive capacity which were aggregated to provide an index of vulnerability. These components were integrated and modelled using GIS by identifying exposure to natural hazards, assessing the sensitivity of major crops to climate variations using ecological model (MaxEnt) under high emission climate scenario (RCP8.5), and identifying key aspects of adaptive capacity. Additionally, we also analyzed the perception of stakeholders towards vulnerability using participatory approaches. This enabled us to identify areas of exposure and vulnerability, and pointed areas of greatest need for strengthened adaptive capacity and risk management. Our findings suggested that majority of the towns in the north and central portions of the BRB will largely experience increased vulnerability, particularly, in the Thiris sub-basin including some parts of Ragay Hills, Waras-Lalo and the northwestern Libmanan-Pulantuna sub-basins. On the contrary, the entire Quinali sub-basin in the south revealed to have the lowest vulnerability index. The information derived from the study can be utilized to reinforce local-based climate policies.
