Co-management of protected areas by NGOs and African countries helps reduce deforestation
In order to better protect ecosystems and biodiversity, several African countries have set up innovative management models in which protected areas are co-managed by government bodies and international or national NGOs through partnerships that can span several decades. An international research team, led by INRAE and involving Le Havre University, reviews this collaborative management model in 127 partnerships covering almost 1 million square kilometres.

What are the consequences of deforestation and tropical forest degradation on ecosystems?
An international team of researchers from the AMAP laboratory (Botany and Modeling of Plant and Vegetation Architecture), under the auspices of the University of Montpellier and INRAE, has investigated the consequences of deforestation and degradation of tropical forests. The study, published in the journal Nature Ecology & Evolution on December 10, identified "winning" and "losing" species, leading to the functional impoverishment of tropical forest ecosystems.

Bioethanol: optimising wood pre-treatment for profitable production
Various complex processes enable the release of the sugars contained in wood, which are used in particular to produce second-generation bioethanol. Scientists from INRAE, the University of Reims-Champagne-Ardenne and the company Européenne de Biomasse have identified ranges of technological trade-off (temperature and pre-treatment time) that enable oak and poplar residues to be reclaimed while minimising the economic investment.

Maritime pine seeds remember temperature conditions
The seeds of maritime pines remember the temperatures they experienced during early development. This memory persists in young trees for at least two years after germination. The above discovery was made by researchers at INRAE, CEA, FCBA, the University of Orléans, the University of Perpignan, and the University of Lisbon.

Monitoring biodiversity: an embedded camera that captures even the most elusive organisms
Observe almost any animal or plant, in any weather, day or night. This has been made possible thanks to the work of an international team, led by researchers from Westlake University, China in collaboration with INRAE, who have designed an embedded vision camera capable of analysing images in real time.

Biomass: a source of innovative molecules & materials
INRAE scientists are exploring how products and byproducts can be transformed into new molecules and biomaterials with utility in a wide range of sectors, including the pharmaceutical, cosmetic, medical, chemical, agricultural, food processing, automotive, and construction industries. Building a strong bioeconomy is crucial if we wish to achieve carbon neutrality and limit greenhouse gas emissions by 2050.

Species diversification to help forests adapt to extreme drought
The changing climate is leaving forests greatly exposed to droughts and intense heat waves, adversely affecting the strength of the trees. One current route being explored to improve forest resilience is that of increasing species diversity.

How climate change affects deer
A European study, led by the Swedish University of Agricultural Sciences with the participation of INRAE, reviewed 20 years of research into the effects of climate change on deer populations in Europe, Asia and North America. The review, published in Global Change Biology, covered 218 scientific articles and showed that while many deer populations benefit from warmer winters, they may not be able to adapt to hotter and drier summers, which could push the animals towards more northerly areas.

New map reveals discrepancies in protection for watercourses in France
The Water Law protects freshwater ecosystems by regulating activities and infrastructure with a potential impact on watercourses, whose legal definition was established in 2015. A research team at INRAE has developed the first national watercourse map. This map reveals disparities in how this definition is applied from one French département (administrative region) to another, to the detriment of small headwater streams - which are often rich in biodiversity - and intermittent streams.

Diversifying forests to adapt to extreme drought
Climate change is exposing forests to severe drought and heatwaves, leading to a weakening of the trees. One way of improving forest resistance is to diversify the species composition of forests. In a study published on September 24 in Global Change Biology and based on data from 5 experimental forests, an international consortium of scientists, involving INRAE and CIRAD and co-financed by ADEME, shows that 2 factors improve trees' chances of survival in mixed forests: the identity of the species concerned and the species composition of the forest .

The influence of political dynamics on biodiversity preservation: the case of the United States
Protected areas have historically been created to preserve biodiversity, but they are not immune to political decisions. Using the United States as an example, and relying on data from 2001 to 2018, researchers from INRAE, the Institut Agro Montpellier, Duke University and WWF have demonstrated that a shift to a Republican majority in state government increases the risk of reducing or downgrading protected areas.

New mapping reveals inequalities in river protection in France
To protect freshwater ecosystems, the Water Act regulates activities and facilities that can impact watercourses, which have been legally defined since 2015. Researchers at INRAE have drawn up the first national map of watercourses, which reveals inequalities between départements in the application of this definition, to the detriment of small streams at the head of basins, often rich in biodiversity, and intermittent streams.

Potential economic and climatic impacts of windstorms in forests
Windstorms are extreme climatic events: rare occurrences with high environmental and economic costs. INRAE and AgroParisTech researchers used foresight modelling to simulate the effects of windstorms on French forests-important carbon sinks-and the French forestry industry through 2050. In one quarter of simulations, windstorms caused a 24% drop in carbon sequestration.

Extent of CO2 and CO ices in the trans-Neptunian region revealed by JWST
Publication of the LGL-TPE in the journal Nature Astronomy on May 22, 2024. Communication by CNRS Earth & Space on June 19, 2024. Carbon dioxide (CO2) is one of the most abundant ices in the Solar System. It has been detected in giant planet atmospheres and on their moons, on and around comets, and even in regions of Mercury, the Moon and Mars.

Planet 9, do you copy?
Planet 9, do you copy?
For nearly ten years, astronomers have been trying to demonstrate the existence of a massive object thought to be orbiting in the outer reaches of the Solar System. Although the hypothesis is widely debated, a recent study claims that the absence of such a body is statistically impossible. Now that Pluto is no longer considered a true planet, the Solar System counts just eight such bodies.

Warming and nutrient enrichment: The combined effects on freshwater systems
In freshwater environments, warming and nutrient enrichment are reducing the diversity of freshwater food-webs, whose richness and complexity are essential to the well-being of ecosystems. This is what researchers from INRAE, Oxford University, the University of Sheffield and Savoie Mont Blanc University have demonstrated by combining large-scale data from lakes and rivers in France.

Drylands: unexpected plant diversity enables adaptation to extreme climates
Three scientists from INRAE, the CNRS and the King Abdullah University of Science and Technology in Saudi Arabia have coordinated a large-scale international study involving 120 scientists from 27 countries to understand how the plants found in drylands have adapted to these extreme habitats. For 8 years, the teams collected samples from several hundred selected dryland plots across six continents, enabling the analysis of over 1300 sets of observations of 300+ plant species, a first on this scale.

Predicting a crop field’s weather
As the world tries to adapt to climate change, a major challenge is accurately predicting local-level meteorological conditions, such as those found in agricultural landscapes. INRAE researchers recently made a significant step forward: using a supercomputer, they simulated a forest plot's micrometeorological conditions in the early morning.
