Patterns and controls on island-wide aboveground biomass accumulation in second-growth forests of Puerto Rico

Background

Secondary or second-growth forests after land abandonment are a valuable contribution to global carbon sinks. Approximately 70% of the world’s tropical forests are secondary growth, so understanding the carbon sequestration rates on a large scale is important. Sequestration rates are controlled by both abiotic and biotic factors in each region.

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.

Ten principles for restoring campo rupestre, a threatened tropical, megadiverse, nutrient-impoverished montane grassland

Background

In the U.N. Decade on Ecosystem Restoration, one of the most overlooked ecosystem types is tropical grasslands. Studies on these ecosystems are lacking, as are the foundations for restoration. These foundational points of policy, practice, and governance in addition to science need to be addressed. The authors provide 10 principles to restore the campo rupestre, a tropical grassland that is threatened by human activities including mining.

Assisted restoration interventions drive functional recovery of tropical wet forest tree communities

Background

Integrating science and practice is one of the main goals of the U.N. Decade on Ecosystem Restoration. A variety of factors can influence the application of restoration treatments across tropical ecosystems. Deciding where to apply a restoration strategy on the spectrum between natural regeneration an active restoration planting can be challenging and there is not enough current knowledge that compares these methods.

Identifying hotspots for ecosystem restoration across heterogeneous tropical savannah-dominated regions

Background

In the U.N. Decade on Ecosystem Restoration, ecological restoration projects are a valuable tool for meeting global sustainability climate goals. Tropical regions are at the center of attention for their high biodiversity, carbon sink, and benefits to culture and human livelihood. Tropical dry savannahs are understudied even though they cover a large portion of tropical regions. Savannah dominated landscapes are valuable for their high plant diversity and vegetation type variation and high species turnover. Benefits to restoring these ecosystem types are also understudied.

Tropical forest restoration under future climate change

Background

Climate change mitigation requires a large amount of carbon sequestration from the atmosphere. One major avenue for accomplishing this is looking to tropical forests. These ecosystems are heavy carbon sinks and bring a multitude of benefits to people and the planet. However, these ecosystems are frequently degraded and forest restoration projects may be hindered in the future due to altered fire regimes, extreme heat or drought, and other characteristics of severe climate change.

The importance of insects on land and in water: a tropical view

Background

Insects provide a wide variety of ecosystem services such as pollination, nutrient cycling, and seed dispersal. The UN Sustainable Development Goals are thought to be supported by the conservation of diverse insect communities. The roles of tropical insects in ecosystem services and their contributions are summarized in this literature review. The authors identify research trends, knowledge gaps, and potential avenues for future investigations.

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.

Why bees are critical for achieving sustainable development

Background

Bees are the most dominant group of pollinators and they may hold a key to achieving the United Nation’s Sustainable Development Goals (SDGs). They have a great potential for promoting agricultural success, providing people with crop pollination services. However bee populations are declining due to habitat loss, pesticide use, and climate change. Knowing the extent to which bees contribute to SDGs  and identifying their critical roles within SDGs is important for conservation targeting.
