Widening the scope of forest-based mitigation options in the tropics

The scope of tropical forest policies has expanded since Kyoto in 1995, from an initial focus on afforestation to the much broader concept of REDD+, which applies to a larger set of territories, services and products – locally and globally.

Economics of Ecosystems and Biodiversity: nature conservation and climate policy are mutually beneficial (Germany)

A new study has assessed the value of ecosystem-based approaches to mitigating climate changes and conserving biodiversity in Germany. The researchers highlight the trade-offs and synergies between climate adaptation and nature conservation and suggest that effective ecosystem-based climate policy requires improved coordination between different sectors, such as agriculture, forestry and energy.

NTFP harvesters as citizen scientists: Validating traditional and crowdsourced knowledge on seed production of Brazil nut trees in the Peruvian Amazon - Forests, Trees and Agroforestry

Understanding the factors that underlie the production of non-timber forest products (NTFPs), as well as regularly monitoring production levels, are key to allow sustainability assessments of NTFP extractive economies. Brazil nut (Bertholletia excelsa, Lecythidaceae) seed harvesting from natural forests is one of the cornerstone NTFP economies in Amazonia. In the Peruvian Amazon it is organized in a concession system. Drawing …

Land disturbance effects of roads in runoff and sediment production on dry-tropical settings - ScienceDirect

Land disturbance effects of roads in runoff and sediment production on dry-tropical settings - ScienceDirect | Ecosystèmes Tropicaux | Scoop.it
Publication date: 15 January 2018
Source:Geoderma, Volume 310
Author(s): Carlos E. Ramos-Scharrón
Accelerated soil loss due to human land use is still one the most critical environmental problems as it can degrade both soils and downstream resources. Major gaps still exist in our knowledge of erosion, particularly in the dry tropics that make up about a fourth of the world's tropical landmass. The Insular Caribbean presents a particular need because erosion here has deleterious effects on soils, nearshore coral reefs, and their associated myriad of ecosystem services. Through plot-scale monitoring of runoff and sediment production over an eleven-month period, this study quantified the impacts of land disturbance on runoff development and sediment production relative to background rates on disturbed surfaces (i.e., roads) in a dry tropical area of Puerto Rico. Results demonstrate that unpaved road surfaces have the potential to generate runoff two to three-and-a-half times more frequently than under natural conditions and that they can produce sediment at rates that are between six to two-hundred times greater than background. These results suggest that land development in small dry-tropical coastal watersheds can potentially induce an increase in the frequency of runoff and sediment delivery into coastal waters even when a relatively small percentage of the land is disturbed. Soil formation simply cannot keep up with accelerated erosion, which implies a net exhaustion of the soil mantle and a decay of the ecological services it provides. Offsetting these soil losses will require implementing proven conservation practices to protect soils and coral reef ecosystems in this and other dry tropical settings.

Taking responsibility for sustainability in the private sector. The damaging practice of clearing land by burning has spread across Indonesia since at least the 1990s, employed by large and small businesses alike. The devastating impact of this practice was brought to international attention when it sparked a regional environmental and public health crisis in 2014-2015. Burning, especially on drained peatlands …

European Forest Institute - News | Ecosystèmes Tropicaux | Scoop.it
Forests are of crucial importance for Natura 2000, the EU-wide ecological network of protected areas. Nearly 25% of the total forest area in the EU is part of the network, but knowledge about how Natura 2000 is implemented in forests, and its effects on biodiversity, forest management and other land uses across the EU is fragmented.
The new What Science Can Tell Us Study from EFI, ‘Natura 2000 and forests: Assessing the state of implementation and effectiveness’, bridges this gap in knowledge. It looks from policy, economic and ecological perspectives at the monitoring of forest biodiversity in Europe, as well as the challenges, achievements, effectiveness and efficiency of the implementation of Natura 2000 in forests in the EU.
Lauri Hetemäki, EFI Assistant Director said: “the new EFI study brings together scientific knowledge and makes recommendations to help policy makers to deal with the many issues related to the practical implementation of biodiversity in EU forests.”
The interdisciplinary scientific study was conducted by a team of 20 scientists from 11 research institutes in 11 countries. Ten of EFI’s Associate Members were involved.
The study’s main outcomes and policy recommendations will be discussed at the ThinkForest seminar, ‘Implementing Natura 2000 in forests: Lessons learned and looking ahead’ in Brussels on 27 September. More information can be found here: http://www.efi.int/portal/policy_advice/thinkforest/upcoming_events/
