Abstract | Links | BibTeX | Tags: orangutan @conference{nokey,Interaction between humans and orangutans can hurt both parties. Crop losses and heightened fear and anxiety among local communities due to orangutan presence often contribute to negative perceptions, which may influence actions towards these primates. Additionally, limited public awareness regarding the risks of keeping orangutans as pets can elevate the potential for zoonotic disease transmission. Habitat loss caused by deforestation and the conversion of forests to agricultural or anthropogenic-used land exacerbates the risk of human-orangutan encounters in Kalimantan. Consequently, understanding these interactions’ trends and spatial distribution is essential for devising strategic interventions to mitigate the conflict. Using web scraping methods, we collected article data from various Indonesian news sources from 2011 to 2024. 172 human and orangutan negative interactions were documented and categorized into six types: orangutan sightings, attacks, crop damage/raiding, hunting, capture, and orangutan rearing. These interactions occurred across 125 villages from 28 districts/cities in Kalimantan. Most incidents were reported in settlement areas (35%) and plantations (45%). Orangutans have also been sighted in public places, such as airports and harbors, over the past 5 years. Given the broad distribution of these interactions, coordinated efforts among multiple stakeholders are crucial for mitigating and managing human-orangutan conflicts as part of broader Bornean orangutan conservation initiatives. |

Abstract | Links | BibTeX | Tags: orangutan @conference{Condro2019,Primates, the closest living biological relatives with human, play the important roles in the livelihoods, human-health, and ecosystem services. In the Anthropocene, populations of 75% of primate species are decreasing globally – due to cultivation activities, logging harvesting, hunting, and climate change. In this study, we focus on Bornean orangutan (Pongo pygmaeus) as the global conservation icons. Hence, understanding Bornean orangutan’s distribution dynamics is crucial regarding to conservation and climate mitigation strategies. The objectives of this study are: (1) to predict current and future spatial distribution of orangutan in Borneo using pessimistic climate model and land cover projection as well; (2) to identify spatial dynamics of Bornean orangutan distribution due to climate and land cover change in 2030. Species distribution modelling of baseline and future scenario was performed using logistic regression model. Land cover categories and climate parameters (i.e. annual temperature and precipitation) were used for model predictors. Presence points of observed primate species were retrieved from Ministry of Environment and Forestry Indonesia (MoEF). We used WorldClim v2.0 annual temperature and precipitation data for the baseline and CMIP5 MIROC-ESM model RCP8.5 2030 for the future climate scenario. We performed cellular automata algorithm to retrieve 2030 projected land-use for the future. Distance to road and distance to selected important land covers were used for transition potential modelling of land cover projection. Generally, the prediction shows that suitable habitat of Bornean orangutan will decrease in 2030. However, we found the gain of suitable area of Bornean orangutan. Findings of this study should support the identification of priority conservation area of Bornean orangutan for the future and wildlife corridor management planning. |
