Understanding ecosystems from an integrated perspective that includes human activities is essential for addressing environmental issues under ongoing climate change. Whereas tropical rainforests have received much attention for their large biomass and high diversity, seasonally dry tropical forests have received less attention, even though they cover about 40% of the tropical region. Climate change is expected to intensify climatic extremes, raising concerns about the vulnerability of seasonally dry tropical forests. While most dry forests around the tropics are degraded or fragmented, Ankarafantsika National Park in northwestern Madagascar harbors large remnants of natural dry forests, on which local communities sustainably depend for their livelihoods. However, these forests have recently been threatened by increasing anthropogenic disturbances and by climate change. Therefore, it is urgent to understand the ecosystem, including human activities, in order to ensure the sustainability of local communities. Following decades of zoological studies in the Ankarafantsika forests, a botanical research project was launched in 2019. After establishing a 15-ha long-term forest dynamics monitoring plot, our data are revealing ecological characteristics of plants, animals, and their interactions. In this symposium, we aim to develop an integrated understanding of the dry forest ecosystem, focusing on the interactions among soil, plants, animals, and human activities. Each presenter will discuss their respective topic related to the ecosystem of Ankarafantsika National Park, drawing comparisons with previous studies conducted in other regions. Following the presentations, we will hold an open session involving the commentator and audience participants to discuss the importance and future directions of dry forest studies in Madagascar and in the world.
