Leverage points for improving global food security and the environment

BACKGROUND

Meeting global food demands is still a challenge, yet agriculture has been one of the main driving forces of greenhouse gas emissions. Hence, this study focused on identifying small regions, actions that can be taken and crops with a potential of increasing global yields, with an efficient system of food delivery and reducing the negative impacts of agriculture on the environment.

Growth of native tree species planted in montane reforestation projects in the Colombian and Ecuadorian Andes differs among site and species

BACKGROUND

Tropical Andes in Columbia and Ecuador have been affected by forest clearance and degradation for several centuries. Agriculture has been the primary driver of land use change as well as mining to a lesser extent. To restore the degraded sites, native species have been used in various projects, however with little information on growth performance of the planted tree species in relation to site and soil nutrient status. A greater part of the northern Andes has volcanic ash derived soils.

Nitrogen-fixing trees inhibit growth of regenerating Costa Rican rainforests

BACKGROUND

Nitrogen fixing plants are the primary source of nitrogen in forests, and it is expected that more nitrogen fixers will bring in faster growth. Hence this study conducted, in a humid tropical rainforest North- East Costa Rica, challenged this notion. The area of study had similar dominant species, with P. macroloba being the most dominant Nitrogen fixer.

Pest management through tropical tree conservation

Background

Deforestation and crop monocultures in Veracruz, Mexico are leading to the disappearance of indigenous trees and the animal species that depend on them. This is particularly troubling to local agricultural workers who benefit from species like hymenopteran parasitoids that attack pest fruit flies. This research evaluates the relationship between hymenopteran parasitoids, pest fruit flies and their fruit hosts and proposes potential strategies for conservation and pest management.

Carbon farming with bamboos in Africa: A call for action

BACKGROUND

Bamboos are of paramount importance for livelihoods, landscapes, and climate change mitigation. When compared to other regions, little research has been done about bamboo resources in Africa. This is because National Forest Resources Assessments rarely capture the necessary data. Approximately, there are 38 species of woody bamboos native to sub-Saharan Africa including Madagascar with many endemic species. So far, their population is dwindling but if sustainably managed, they can contribute significantly economically and to the environment.

Safety Nets, Gap Filling and Forests: A Global-Comparative Perspective

BACKGROUND

This paper seeks to prove how forests and wildlands are utilized in developing countries as safety nets to shocks, and how they provide resources for seasonal gap filling. The study was carried out in various developing countries in different continents. Areas where there is no forest at all were excluded and those completely forest covered such as those dominated by hunter- gatherers were not considered.

Impact of Forest Management on Insect Abundance and Damage in a Lowland Tropical Forest in Southern Cameroon

Background

A burgeoning timber industry in Cameroon, which became the fifth largest producer of timber in the world in the 1990’s, led to unsustainably high deforestation rates and high demand for forest regeneration interventions. Research in the Mbalmayo Forest Reserve in southern Cameroon has compared different silvicultural techniques for forest regeneration including complete and partial clearance methods.

Leaf litter arthropod responses to tropical forest restoration

Background

Soil and litter arthropods play critical roles in tropical ecosystem function including driving organic matter decomposition and nitrogen mineralization. With the increasing need for forest restoration projects, it is important to know how these arthropod communities respond to a variety of restoration strategies and techniques in order to maintain healthy ecosystem function. This study was conducted in a mixed-use agricultural landscape in southern Costa Rica, in an effort to contribute to local restoration research efforts.

Fuelwood collection and its impacts on a protected tropical mountain forest in Uganda.

Background

This study examined the patterns, effects and potential management of fuelwood extraction on the forest of Mt Elgon, located in the Eastern part of Uganda, Sub- Saharan Africa. Fuelwood is the main source of energy, mainly collected from the forest. 98% of the households use fuelwood and charcoal for cooking and heating. This is a protected area with a history of conflict between surrounding populations and conservation actors. No other forest remains in its direct vicinity.

Ecosystem-based adaptation for smallholder farmers: Definitions, opportunities and constraints

background

Ecosystem-based Adaptation (EbA) or the use of biodiversity and ecosystem services has been gaining recognition as being a vital part of the overall strategy to help people adapt to the adverse effects of climate change. This study recognizes the importance of EbA in helping smallholder farmers adapt to climate change while providing co-benefits such as livelihood, continued provision of a variety of ecosystem services, and conservation of existing resources.
