Leverage points for improving global food security and the environmentBACKGROUNDMeeting 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.

Pest management through tropical tree conservationBackgroundDeforestation 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.

Building Pastoral and Agro-Pastoral Community Resilience Against Drought in the Context of the Paris Agreement: The Case of Isiolo County, KenyaBACKGROUNDUnder the Paris Agreement, countries that are party to the negotiations are obliged to meet its National Determined Contributions (NDC). Kenya, a member state of the United Nations Framework Convention on Climate Change or UNFCCC, has made strides in the climate change arena, keeping up with its NDCs and establishing climate change legislation and policy measures. This chapter provides insights on how resilience building amidst the climate-change induced droughts is possible through multi-stakeholder collaboration between pastoral and agro-pastoral communities, county and the national government.

Biofuels: The Impact of Oil Palm on Forests and ClimateBackgroundThis publication summarizes the proceedings of a 2009 conference held Singapore titled "Biofuels: The Impact of Oil Palm on Forests and Climate". With the emergence of palm oil industry, particularly in Asia, there has been a strong debate concerning the ability of this and other biofuels to reduce greenhouse gases but also its contribution to large-scale land conversion. This conference aimed to bring together experts from various fields to discuss potential solutions or alternatives to the industry. The report summarizes the opening remarks of the conference along with four panels, each of which were based on a specific question. Open access copy available |
Functional divesity changes during tropical forest successionBackgroundThis paper evaluates changes in species richness and functional diversity during tropical secondary forest succession following shifting cultivation in Chiapas, Mexico, particularly examining whether speces richness is a good predictor of functional diversity. Functional diversity was calculated based on a combination of nine functional traits, and two individual traits important for primary production (specific leaf area) and carbon sequestration (wood density).

Policy Options for the World's Primary Forests in Multilateral Environmental AgreementsBackgroundAround the world, primary forest continue to decline. The authors of this article recognize that international forest policies is one means to slow or turn around these trends and thus they identify four new actions that can provide a policy foundation for key international negotiations.

Targeted habitat restoration can reduce extinction rates in fragmented forestsBackgroundHabitat lost is one of the primary drivers of species extinction. This study examines two highly-fractured ecosystems, the Eastern Arc Mountains of Tanzania and the Atlantic Forest of Brazil, and evaluates the rate at which habitat loss may lead to extinction and thus biodiversity loss. Specifically, the authors use halflife vs. area relationship to determine how long it will take to lose one-half of all tropical bird communities in each habitat. Open access copy available |
Tropical forest restoration: Fast resilience of plant biomass contrasts with slow recovery of stable soil C stocksBackgroundThe study looks at three land-use types: 1) land left barren after a clear-cut in the 1950s, with only a sparse cover of shrubs, grasses, and vines, 2) a Eucalyptus exserta plantation established in the 1960s, and 3) a eucalyptus plantation that was clear-cut in 1974 and converted into a plantation of native tree species, now considered a secondary forest. The biomass and soil carbon (C) of these three land-use types were compared to a nearby natural old-growth forest. Open access copy available |
Restoration of Ecosystem Carbon Stocks following Exclosure Establisment in Communal Grazing Lands in Tigray, EthiopiaBackgroundThe study examines changes in ecosystem Carbon stocks (ECS) after the establishment of exclosures on communal grazing lands. Exclosures are areas where livestock are prohibited from grazing. Available with subscription or purchase |
Drug Policy as Conservation Policy: Narco-DeforestationBackgroundCentral America exploded into prominence as a drug trafficking corridor in the last decade. The authors documented that an unprecedented flow of cocaine into Central America “coincided with a period of extensive forest loss”. The authors discuss the evidence that supports the idea that "trafficking of drugs (principally cocaine) has become a crucial—and overlooked—accelerant of forest loss” in Central America.
