On August 3, ELTI lost a dear friend and colleague with the death of Dr. Arbainsyah (known as “Insya”) due to Covid-19. Insya worked with ELTI in East Kalimantan (Indonesian Borneo) since 2017, first as the Indonesia Program Assistant and then as the Indonesia Program Coordinator. Insya’s loss is truly heartbreaking for us at ELTI. His hard work and dedication will live on as a legacy in both the landscapes that he helped to restore and in the hearts of everyone he trained and mentored along the way.

Please join us in celebrating Insya’s work with ELTI by learning about his training innovations, his work in the field, and the many publications that he developed with partners and colleagues. Link to detailed tribute:

ELTI affiliates in Panama recently attended the closing ceremony for farmers from the Coclé Province who participated in the project: Sustainable Livestock in the Middle and Lower Watersheds of the Santa María River as a Measure of Adaptation to Climate Change. Over the past two years, this project, the largest sustainable cattle ranching project ever implemented in Panama to date, has established 600 hectares of silvopastoral systems with 120 farmers in three provinces of Panama. ELTI along with ELTI’s primary partner in Colombia, the Center for Research on Sustainable Agriculture (CIPAV) were members of a consortium led by the Group for Sustainable Environmental Education and Management (GEMAS) to carry out the project, which was funded by the Adaptation Fund. In 2019 ELTI trained the 120 farmers on silvopastoral systems via their Panama Training Landscape and helped them develop their farm management plans, the first step of the project. For ELTI affiliates, it was inspiring to attend the closing ceremony and witness the results of the project participants such as, Jorge Cedeño, who had converted his conventional pastures into an intensive silvopastoral system and increased the milk production of his dairy farm by 50%.

Mushrooms have long been used by humans both as a food source and as a medicinal ingredient. There are many types of mushrooms that can be cultivated. Two of the most common in Indonesia are Straw mushrooms and Oyster mushrooms, although the production and consumption of mushrooms remains quite low. A recent ELTI online course entitled, "Introducing Oyster and Straw Mushroom Cultivation Techniques for Communities Around Oil Palm Plantations" aimed to help local community members in areas surrounding oil palm plantations develop mushroom production as an alternative livelihood.

January 4, 2021 | Mongabay

Mongabay published an article written by ELTI alumnus David Woodbury and ELTI affiliate Arbainsyah about their research on degraded mine sites in East Kalimantan, Indonesia. The article entitled, “Being realistic about coal mine rehabilitation in Indonesia: An ecological perspective,” describes the challenges associated with an Indonesian law that requires mining companies to restore the degraded land to its “original condition,” an unrealistic target. The accepted solution by the Indonesian government to restoring degraded land is ecological rehabilitation. But ecological rehabilitation cannot restore the land to its “original condition,” and this goal may not align with local community interests or with ecological recovery. You can read the Mongabay article here and find the journal article in Land Degradation & Development here, written in collaboration with other researchers at the Yale School of the Environment, Tropenbos Indonesia and the Indonesian Ministry of Forestry and the Environment.

David and Arbainsyah conducted their research around ELTI's training landscape in Indonesia with in-kind support from the ELTI Indonesia Program and Balitek-KSDA.

April 24, 2020 | Restoration Ecology

Zoraida Calle, CIPAV researcher and ELTI affiliate, co-authored a research article entitled, “Decline in local ecological knowledge in the Colombian Andes may constrain silvopastoral tree diversity” published in the Restoration Ecology journal. Following up on a survey of workers, managers and owners of silvopastoral farms in the Colombian Andes six years later, the authors found that the ability to identify native trees and describe their uses was significantly lower, as well as the interest in planting trees.

The study shows that knowledge about the uses of native species is critical for motivating cultivation of diverse trees in silvopastoral farms, and that multipurpose trees are the most likely to be planted. The authors concluded that local knowledge on the ecology and use of native species plays a critical role on decisions made by cattle farmers about the trees they plant in their farms. “Perhaps it is time to treat local ecological knowledge as what it really is: an irreplaceable treasure,” said Zoraida.

The Roundtable on Sustainable Palm Oil requires that member companies protect, manage and restore High Conservation Value areas within their plantations. An example are areas with “concentrations of biological diversity including endemic species, and rare, threatened or endangered species, that are significant at global, regional or national levels.”

A new livelihood opportunity for communities living around High Conservation Value areas is to raise stingless bees for honey, bee pollen and propolis.

In partnership with Tropenbos Indonesia, Balitek KSDA and Goodhope Asia Holding Ltd., ELTI facilitated a field course in Indonesia to provide conservation managers of oil palm plantations and community members with the knowledge and skills needed to work together to promote stingless beekeeping  for the benefit of biodiversity and community livelihood.

April 14, 2020 | ELTI, Blue Forest Foundation, Tropenbos Indonesia, Balitek-KSDA and Pertamina EP

ELTI’s Indonesia Program, in collaboration with Blue Forest Foundation, Tropenbos Indonesia and Balitek-KSDA, published a book entitled, Bekantan dan Habitatnya di Sungai Hitam (in English, Proboscis Monkey and Their Habitat at the Sungai Hitam Mangrove Forest). The book outlines the results of a social and ecological assessment conducted to determine the best way forward to rehabilitate a riparian habitat for the proboscis monkey in the ELTI training landscape in East Kalimantan, Indonesia. Pertamina EP supported the printing of this publication.

This video features the ELTI field course “Mangrove Forest Restoration and Rehabilitation Techniques,” held in East Kalimantan, Indonesia in November 2019. This field course was designed to increase participant capacity to engage in mangrove rehabilitation.

Indonesia has the largest area of mangrove forest in Southeast Asia. The rate of deforestation, however, is very high, reaching 40% over the last thirty years. This high rate is largely due to coastal development and conversion to shrimp and fish ponds.

ELTI, Tropenbos Indonesia and other local partners have been working together to maintain, restore and improve the function of a mangrove forest as a Proboscis monkey habitat in Sungai Hitam, East Kalimantan. Mangrove forest rehabilitation is aimed at ensuring the sustainability of Proboscis monkeys while enhancing local community livelihoods.


March 10, 2020 | GEF Small Grants Programme

In one of the most deforested regions of Panama, the Azuero Peninsula, water is becoming very limited for livestock during dry seasons. Farmers are struggling to adapt to the effects of climate change and are seeking innovative approaches to manage natural resources more sustainably.

ELTI alumni and members of the Save a Tree, Live Better Ecological Producer’s Association (SAVIM) received $20,000 USD in support from the Global Environmental Facility's Small Grants Programme to explore a promising innovative solution to limited water supply.

Over the next 15 months, the famers will establish three rainwater harvesting systems to supply water for a native species tree nursery, an agroecological garden at the local primary school and cattle aqueduct for silvopastoral systems.

As the first of its kind in the region, this project will contribute to the UN’s Sustainable Development Goals to reduce environmental impacts while improving the quality of life of local communities. The project will also directly address priorities set forth by the Panamanian government to optimize the use of water resources, soil and climatic conditions to guarantee the production of water throughout the year.

These photos from a Panamanian landscape illustrate the extreme seasonal changes during the year and consequently the increased vulnerability of degraded pastures to provide water and sustain livestock production.

January 30, 2020 | Land Degradation and Development

Restoration techniques for lands degraded from surface-mining are well established in temperate regions. However, until recently, restoration practitioners in East Kalimantan, Indonesia had little scientific guidance on best practices for mine reclamation in moist tropical regions.

Determined to find answers to inform future restoration efforts, ELTI alumnus David Woodbury and collaborators published a paper entitled, “Filling a void: Analysis of early tropical soil and vegetative recovery under leguminous, post-coal mine reforestation plantations in East Kalimantan, Indonesia.” Contrary to the popular practice of planting monocultures of fast-growing leguminous trees on degraded lands, results suggest that this practice alone may not be sufficient to restore native forests. Instead, greater emphasis should be placed on establishing healthy soil from the onset of mine rehabilitation projects, which will build the forest’s foundation for recovery.

David conducted his research around ELTI's training landscape in Indonesia with in-kind support from the ELTI Indonesia Program.


January 30, 2020 | CANOPY by the Yale School of Forestry and Environmental Studies

October 27, 2019 | Visayas State University

ELTI and Visayas State University are celebrating their longstanding partnership in the Philippines. Since 2009, ELTI has partnered with the university’s Institute of Tropical Ecology and Environmental Management (ITEEM) with the shared mission of empowering local communities to design and implement sustainable land-use practices, and to conserve and restore tropical forests and native tree cover in human-dominated landscapes.

One of the key approaches used by ITEEM and ELTI is Rainforestation Farming. This agroforestry approach aims to restore ecosystem functions and services by harnessing the power of native species, local communities, and partner organizations to rehabilitate degraded landscapes. By providing more than 25 field trainings and reaching over 700 individuals, ELTI and ITEEM have demonstrated the potential of Rainforestation to address ongoing environmental challenges and to strengthen community resiliency in the Philippines. In light of the ten-year anniversary, ELTI will continue to conduct field trainings and hopes to conduct a nationwide survey of all ELTI alumni in the Philippines.

October 11, 2019 | The Sustainability Agenda

ELTI Director Dr. Eva Garen was featured on The Sustainability Agenda podcast to discuss ELTI’s work in Latin America and Southeast Asia. The Sustainability Agenda explores innovative approaches to sustainability around the world. Dr. Garen shared ELTI’s approach to capacity development and restoration, with insights from her 25+ years working on the social aspects of conservation and development in the tropics.

The ELTI Indonesia program in partnership with the Research Institute for Natural Resources Conservation Technology (Balitek KSDA) developed a leaflet to encourage ecotourism in the riparian forest of Sungai Hitam in Samboja, East Kalimantan, Indonesia.

The riparian forest of the Sungai Hitam River provides critical habitat for the endangered Proboscis monkey (Nasalis larvatus) but is threatened by the fact that the region is not part of a protected area. Currently, the riparian zone is fragmented by other land uses including plantations, agriculture, livestock, mining and municipal waste management. To address these habitat issues, tours in which visitors can watch monkeys and birds from the comfort of a boat will be offered, and funding for habitat restoration and protection will increase. In addition to increasing funding for the conservation of habitats of the Proboscis monkey, ecotourism is an important opportunity to gain local support to protect this important species, restore their habitat and enhance community livelihoods.

Water shortages in Panama’s La Villa River watershed are becoming a problem for both farmers and cities in the Azuero Peninsula. With over 78% of the watershed deforested due mostly to conventional agriculture and ranching practices, more sustainable land-management activities are needed.

With support from the Conservation, Food & Health Foundation, ELTI will train and support farmers and extension agents within the La Villa River watershed to become environmental leaders. ELTI was selected from a pool of 300 applicants to apply our training-of-trainers model, which offers experiential learning opportunities for farmers to learn from ELTI and local experts about land management practices at ELTI’s Panama Azuero training landscape. ELTI will provide follow-up training to help farmers establish and manage model farms, as well as learn how to share their knowledge and experience. By demonstrating and communicating results to others, this group of environmental leaders will help to replicate more sustainable farming throughout the region.
