Shaded-Coffee: A Nature-Based Strategy for Coffee Production Under Climate Change? A Review

Background

Coffee agroforestry systems are a natural climate solution that are used to reduce the impact of coffee cultivation on ecosystem health. Coffee generates over $200 billion in income globally each year, so ensuring the efficiency and success of cultivation is crucial for human livelihood. Coffee agroforestry systems are often variable, and there lacks a compiled knowledge base about these systems and practices.

The Embedded Agroecology of Coffee Agroforestry: A Contextualized Review of Smallholder Farmers’ Adoption and Resistance

Background

Agroforestry crops are known to provide many benefits to both people and nature. Implementing agroforestry practices can be complex and requires improvement in certain regions and practices. Coffee agroforestry is not widely adopted and there is a lack of knowledge about the implementation of agroforestry techniques for coffee production.

Goals and Methods

The authors conduct a literature review including coffee production in Colombia, Malawi, and Uganda to understand their perceptions of coffee agroforestry, decisions on implementation, local policies, and capacity to adopt new practices.

Small scale eucalyptus cultivation and its socioeconomic impacts in Ethiopia: A review of practices and conditions

Background

In order to support growing populations in developing countries such as Ethiopia, people turn to fast-growing crop and timber species to support their livelihoods. Eucalyptus is introduced to Ethiopia for its fuel and construction as well as for its high growing rate and low maintenance costs. There is a current conflict around Eucalyptus cultivation, with many smallholder communities depending on it but clear environmental issues and expansion across farmland boundaries.

The eco-evolutionary history of Madagascar presents unique challenges to tropical forest restoration

Background

Madagascar forests contain high biodiversity and species endemism, while also being heavily threatened by deforestation. Restoration of these forests may be unique to many other restoration projects due to the unique evolutionary history of the island.

Goals and Methods

The authors conduct a literature review of publications to determine if forest restoration in Madagascar is more challenging. With compiled literature from 1990 to 2022, the authors consequently describe unique challenges to Madagascar forest restoration in order to facilitate higher quality restoration projects.

Climate-Smart Conservation Agriculture, Farm Values and Tenure Security: Implications for Climate Change Adaptation and Mitigation in the Congo Basin

Background

The Congo Basin forest houses a high amount of biodiversity and is an important area to conserve in light of climate change. This region is also important for agriculture and local livelihoods, though current practices are degrading the forest. Certain policy issues surrounding land tenure and investments may be hindering climate smart agriculture.

The association between rainforest disturbance and recovery, tree community composition, and community traits in the Yangambi area in the Democratic Republic of the Congo

Background

Forests in the Congo Basin are becoming increasingly threatened by human disturbances. These forests play a crucial role in global biodiversity, though understanding the full impact of forest degradation has been difficult due to the intact canopy cover. It is important to assess the extent that human activities have impacted these forests to make decisions on the forests’ conservation and management practices.

The Effects of Prescribed Dry Season Burning on Woody Species Composition, Mole National Park, Ghana

Background

Savannas are valuable ecological communities that support many species and are known to be heavily shaped by fire disturbances. Fire is a recognized tool for controlling excess fuel and improving habitat. However, it is thought that the timing and frequency of fire prescriptions may impact characteristics of savanna growth and composition.

Suppression of seed production as a long-term strategy in weed biological control: The combined impact of two biocontrol agents on Acacia mearnsii in South Africa

Background

Acacia mearnsii is a woody plant native to Southeastern Australia and Tasmania. Introduced into South Africa in the mid-1800s for timber, the species has become invasive to the region. Reducing the amount of precipitation reaching the ground, hindering agriculture and lowering biodiversity are just a few of the detrimental impacts. Though there has been pushback to controlling this species for commercial interests, two biological control agents, a seed-feeding weevil and a flower-galling midge are known to control species spread and are introduced to the region.

Old timber plantations and secondary forests attain levels of plant diversity and structure similar to primary forests in the West African humid tropics

Background

There is a high rate of biodiversity loss and deforestation in tropical ecosystems. In order to maintain global biodiversity, it is necessary to conserve plant diversity in alternative forest landscapes such as secondary forests and plantations. Comparing conservation values and tradeoffs of different forest landscapes is important for sustainable forest management and conservation practices.

A cautionary note for forest landscape restoration in drylands: cattle production systems in northwest Madagascar’s dry forests

BACKGROUND

It is evident that land tenure security is crucial for successful restoration. Unfortunately, in Madagascar, dry forests are considered unoccupied and unowned even when communities have long-established claims under customary tenure systems. The authors stated that collective tenure recognition efforts were underway in Madagascar, but limited knowledge of agropastoralist cattle production strategies impeded the efforts to develop tenure reforms. The authors examined how cattle raisers in the Boney Region in northwest Madagascar organize pastoral spaces and cattle production strategies in the area’s dry forest.
