Article
Tropical forests are the most diverse and productive ecosystems on Earth. While better understanding of these forests is critical for our collective future, until quite recently efforts to measure and monitor them have been largely disconnected. Networking is essential to discover the answers to questions that transcend borders and the horizons of...

The specialty coffee sector represents opportunities for coffee farmers and other actors due to increased value within the supply chain, driven by elevated consumer purchase prices. We investigated these relationships up to the export stage, as well as the potential for specialty coffee to improve stakeholder participation in biodiversity conservat...

The forest structure and composition of Afromontane forests in Ethiopia, where Arabica coffee is originated and grown as an understorey shrub, have been deteriorating following intensive and ever-increasing management interventions for coffee production. The study conducted in Zege Peninsula Dry Afromontane forest to (1) examine the impacts of coff...
Chapter
The highlands of Ethiopia are home to many plant and animal species, including endemic and globally threatened ones. These highlands are part of the Eastern Afromontane Biodiversity Hotspot, ancient landscapes where human civilization and agriculture originated, and one of Vavilov’s centres of origin and diversity for crop plants worldwide. Besides...
Article
Full-text available
Smallholder farmers dependent on rain-fed agriculture are particularly vulnerable to extreme climate events and, therefore, it is necessary to identify adaptive measures that would increase farmer resilience to these shocks. The management options in a low-input system, like forest coffee (Coffea arabica), are limited and there are several factors...
Article
Full-text available
Forest resources are often well managed by local communities either through their own initiatives using traditional institutions or being organized with assistances from development actors such as non-governmental organization (NGOs) and governmental organizations (GOs). The study was aimed to assess forest management practices, and the contributio...

Arabica coffee (Coffea arabica) is a key crop in many tropical countries and globally provides an export value of over US$13 billion per year. Wild Arabica coffee is of fundamental importance for the global coffee sector and of direct importance within Ethiopia, as a source of harvestable income and planting stock. Published studies show that clima...

Article
Ethiopia has lost 90% of its forest extent. Remnant patches in the southwest are often semi-forest coffee (SFC), a system whereby coffee is managed beneath the canopy. Here, we (1) quantify aboveground live carbon (AGC) stored by trees in SFC and other land use types in the Jimma Highlands; and (2) determine coffee farmers' preference for canopy sh...

Diversity patterns of vascular plant species were studied along geographical gradients in the Afromontane regions of Ethiopia. Vegetation data were sampled from five moist evergreen Afromontane forest fragments, namely Harenna (southeast), Bonga, Maji, Berhane-Kontir and Yayu (southwest). In each forest, quadrats of 20x20 m were laid along transect...
Conference Paper
The Ethiopian moist montane forests host high species diversity and are likely to be strongly affected by climate change, as are tropical mountain forest ecosystems worldwide. It is difficult, however, to estimate the impacts of a changing climate on tropical plant species because their specific environmental requirements are often only incompletel...
