Tropical peatlands in Indonesia are increasingly degraded by conventional oil palm practices involving drainage and chemical fertilizers. This study evaluates AeroHydro Culture (AHC), a method applying microbe-enriched organic media aboveground, as a sustainable alternative that maintains high groundwater levels while supporting plant productivity...

This study investigated the impacts of a farmer field school (FFS) programme focused on farm forestry in arid and semi-arid lands (ASALs) in Kenya from 2017 to 2020. Specifically, we examined whether this agricultural extension approach enhanced livelihood diversification and reduced vulnerability to climate-related shocks among rural households...

In rural Ethiopia, small-scale farmers have suffered from recurrent extreme climate events, such as droughts, that have caused crop failures and the death of livestock. The Farmer Field School (FFS) approach is an agricultural extension approach considered to support climate-resilient farming and livelihoods. Focusing on an FFS project implemented...

In general, it is known that extreme climatic conditions such as El Niño and positive Indian Ocean Dipole (IOD+) cause prolonged drought in Indonesia's tropical peatlands so that groundwater levels (GWL) drop and peat is prone to fire. However, 27 years of GWL measurements in Central Kalimantan peat forests show the opposite condition, where the...

Larch forestry has thrived in Atsuma town under a relatively mild climate and clear-cutting operations have been carried out with well-developed forest roads. Besides, a new trend is emerging. It is a trial-and-error process to find diversity in the way people relate to the forest and reflect it in the way they make a living. The horse logging...

At the end of World War II, the Battle of Okinawa was fought between Allied and Japanese forces on the Okinawa islands. The Battle of Okinawa was a ground war directly involving the people of the prefecture, and 120,000 of the then population of approximately 490,000 were killed. Of these, 94,000 were civilian casualties. After the war, Okinawa was...

At 14:46 on March 11, 2011, the largest earthquake ever recorded, with a magnitude of 9.0 on the Richter scale, occurred, and together with the subsequent tsunami, caused extensive damage along the Pacific coast of the Tohoku region in Japan. The human casualties, as reported by the National Police Agency on April 10, 2015, were 15,891 dead and 2...

Efforts in Aya over the past half century to coexist with nature have been based on collaboration with a diverse range of people and organizations, not only locally but also from all over Japan and abroad. Activities leading up to the present day were triggered by opposition to a deforestation plan in a state-owned forest, but since then, the...

Natural resource management in developing countries is often placed in the context of strengthening climate change resilience. However, the resilience concept is highly abstract. This study will analyze how the resilience concept is reflected in policies, measures, and implementation in Ethiopia and Kenya, two countries with arid and semi-arid...

Peatlands are unique and rare ecosystems that, despite only covering around 3-4% of the planet’s land surface, they contain up to one-third of the world’s soil carbon, which is twice the amount of carbon as found in the world’s forests. Keeping this carbon locked away is absolutely critical to achieving global climate goals. However, about 12% of...
