Une des plus grandes expériences écologiques au monde a révélé qu’en plantant une diversité d’arbres, on peut accélérer la restauration d’une forêt tropicale exploitée.
Dos estudios en dos coníferas mediterráneas amenazadas por el cambio climático investigan las bases genéticas que explican su capacidad de adaptarse, resistir y recuperarse frente a la sequía.
Les forêts semi-décidues d'Afrique de l'Ouest, confrontées à de multiples perturbations liées aux activités humaines, sont au cœur d'une nouvelle étude publiée dans Biological Conservation par l’Institut National Polytechnique Félix Houphouët-Boigny, le Cirad et l’Université de Wageningen. Celle-ci dévoile les conséquences à long terme de perturbations telles que les incendies, l'exploitation forestière et les invasions biologiques sur ces précieux écosystèmes.
Selon les méthodes utilisées, la mesure des stocks et flux de carbone des forêts peut passer du simple au double. À l'heure du dérèglement climatique, la guerre des chiffres bat son plein et la rigueur s'impose pour évaluer les potentiels poumons verts que sont les forêts.

Le nouveau rapport de l'Ipbes révèle la menace majeure que constituent les espèces invasives pour la nature, mais aussi pour l'économie, la sécurité alimentaire et la santé. Les coûts quadruplent tous les dix ans depuis 1970.
A UNESCO and IUCN assessment of the status of species reveals that UNESCO World Heritage sites harbour over 20% of mapped global species richness within just 1% of the Earth’s surface. Safeguarding these
Après des années d’essor en apparence irrésistible, les crédits carbone sont de plus en plus décriés. Souvent sans réels bénéfices pour le climat, ils n’incitent pas les entreprises à se transformer pour réduire leurs émissions de gaz à effet de serre. Cette tendance s’est confirmée dans la Déclaration de Nairobi issue du premier Sommet africain sur le climat, organisé début septembre au Kenya. La Déclaration plaide en faveur d’une taxe internationale sur les émissions de gaz à effet de serre issues des combustibles fossiles.
A new open-access database that documents the observed environmental ranges for most known tree species is tipped to be a key development in climate change adaptation and restoration planning. The Center for International Forestry Research and World Agroforestry (CIFOR-ICRAF) has just released the Tree Globally Observed Environmental Ranges database (TreeGOER), which documents the ranges of […]
This document provides potential monitoring tools to guide monitoring, reporting and learning on forest and landscape restoration, and outlines next steps to operationalise monitoring, reporting and learning in Kenya.

Webinars provide forum for discussion on forests and water 06/09/2023Forests are now widely known for their capacity to store carbon and help mitigate the effects of climate change. But it is only relatively recently that recognition has grown of the vital role they also play in providing water that the world depends upon. So how should forests be managed in order to protect and maximise the ‘water services’ they provide? A series of webinars in coming months - organized jointly by the Food and Agriculture Organization of the United Nations (FAO) and the International Union of Forest Research Organizations (IUFRO) – distils the latest knowledge on forest-water management into three 1.5-hour interactive sessions (21 September, 19 October and 16 November 2023) and provides a rare chance for practitioners and researchers to discuss turning the theory into practice. The sessions - open to professionals in land, forest and water management or forest projects and to scientists and organizations specialising in forests and water – are based on the findings of a series of papers written by IUFRO experts and published in Forest Ecology and Management.
Si les espèces végétales des régions les moins chaudes de la planète se retrouvent souvent inadaptées face au réchauffement climatique, qu'en est-il des espèces de régions déjà chaudes, comme les forêts tropicales ?
L’essor du nombre de plantations dans ce pays d’Afrique de l’Ouest repose sur les avantages que les migrants, en grande partie burkinabés, tirent de l’exploitation.
Several coastal ecosystems—most notably mangroves and tidal marshes—exhibit biogenic feedbacks that are facilitating adjustment to relative sea-level rise (RSLR), including the sequestration of carbon and the trapping of mineral sediment1. The stability of reef-top habitats under RSLR is similarly linked to reef-derived sediment accumulation and the vertical accretion of protective coral reefs2. The persistence of these ecosystems under high rates of RSLR is contested3. Here we show that the probability of vertical adjustment to RSLR inferred from palaeo-stratigraphic observations aligns with contemporary in situ survey measurements. A deficit between tidal marsh and mangrove adjustment and RSLR is likely at 4 mm yr−1 and highly likely at 7 mm yr−1 of RSLR. As rates of RSLR exceed 7 mm yr−1, the probability that reef islands destabilize through increased shoreline erosion and wave over-topping increases. Increased global warming from 1.5 °C to 2.0 °C would double the area of mapped tidal marsh exposed to 4 mm yr−1 of RSLR by between 2080 and 2100. With 3 °C of warming, nearly all the world’s mangrove forests and coral reef islands and almost 40% of mapped tidal marshes are estimated to be exposed to RSLR of at least 7 mm yr−1. Meeting the Paris agreement targets would minimize disruption to coastal ecosystems. Without mitigation, relative sea-level rises under current climate change projections will exceed the capacity of coastal habitats such as mangroves and tidal marshes to adjust, leading to instability and profound changes to coastal ecosystems.
