En matière de gestion de l'eau et des milieux aquatiques, la participation est notamment utilisée dans l'élaboration et la mise en oeuvre des SAGE et contrats de milieu * afin d'impliquer l'ensemble des acteurs concernés et intéressés sur le territoire. Elle est quasi-systématiquement associée aux démarches de gestion, et souvent rendue obligatoire. Elle est devenue à la fois un champ de questionnements et de débats. Comment piloter la dimension politique des projets ? Qui associer ? Avec quel mandat et rôle ? A quelle occasion et quelle fréquence ? Pour quelle part d'accès à la décision ? etc.

Although the relationships between habitats and ecosystem services (ESs) have been acknowledged, investigating spatio-temporal change in these has received far less attention. This study assesses the influence of habitat changes on ES delivery across space and time, based on two time points some 60 years apart, 1946 and 2009. A 1946 aerial photo coverage of two catchments in Scotland was used to construct digital photo mosaics which were then visually interpreted and digitised to derive historic habitat maps.

Effective subnational and local implementation of the National Biodiversity Strategies and Action Plans (NBSAPs) and the Convention on Biological Diversity (CBD) in general depends on two interconnected elements: the capacity of each level of government to develop, execute and monitor their own biodiversity strategies and action plans or related instruments that mainstream biodiversity into their wider objective and cover the obligations of an NBSAP, and the coordination mechanisms between these levels, including synergies across levels of government in planning BSAPs.

Interactions between biodiversity loss and climate change present significant challenges for research, policy and management of ecosystems. Evidence suggests that high species diversity tends to increase plant community stability under interannual climate fluctuations and mild dry and wet events, but the overall pattern of diversity–stability relationships under climate extremes is unclear.

4ème cause de perte de biodiversité dans le monde, les espèces exotiques envahissantes - ou espèces invasives - soulèvent d’importants enjeux environnementaux. Alors qu’une stratégie nationale se met en place pour mieux gérer ces invasions biologiques, Irstea poursuit ses travaux pour améliorer les connaissances et les modes de gestion d’une des espèces végétales les plus envahissantes en France, la renouée du Japon. Mais aussi pour mieux comprendre le comportement de la communauté des espèces invasives dans son ensemble.

Les aires terrestres protégées font-elles assez pour la biodiversité? Probablement pas, estiment des chercheurs dans la revue Nature. Selon leur étude, elles pourraient grandement gagner en efficacité, en allant au-delà du seul critère de la diversité en espèces.

Practical issues for consideration in National Biodiversity Strategies and Action Plans to minimize the use of agrochemicals
Abstract: This Technical Guidance Document addresses the need for mainstreaming biodiversity and ecosystem services into agriculture, at the national level. More specifically, it is aimed to assist countries in developing and implementing their National Biodiversity Strategy and Action Plans (NBSA Ps), to consider ecosystem services – and opportunities for their management – in agricultural production systems. Through an EU -funded project on “Capacity-building related to multilateral agreements (MEA s) in AC P countries (Phase 2)”, this document focuses on the East Africa region, and provides concrete examples and cases primarily from Kenya.

Global areal protection targets have driven a dramatic expansion of the marine protected area (MPA) estate. We analyzed how cost‐effective global MPA expansion has been since the inception of the first global target (set in 1982) in achieving ecoregional representation. By comparing spatial patterns of MPA expansion against optimal MPA estates using the same expansion rates, we show the current MPA estate is both expensive and ineffective. Although the number of ecoregions represented tripled and 12.7% of national waters was protected, 61% of ecoregions and 81% of countries are not 10% protected. Only 10.3% of the national waters of the world would be sufficient to protect 10% of each ecoregion if MPA growth since 1982 strategically targeted underrepresented ecoregions.

Designating protected areas is relatively easy, but hardly anyone seems to be bothering with the hard work of actually protecting them.
Dans le contexte actuel d’anthropisation croissante des milieux, l’identification et la cartographie des derniers espaces de nature sauvage (ou wilderness) deviennent un enjeu majeur dans le domaine de la conservation de la nature. Le concept de naturalité, adaptation francophone de wilderness, est de plus en plus communément utilisé dans la littérature pour désigner différentes qualités, parfois antagonistes, d’un espace. Encore polysémique, ce concept souffre d’un manque de définition et son utilisation pour établir des cartographies est encore marginale

Management of large carnivores is among the most controversial topics in natural resource administration. Regulated hunting is a centrepiece of many carnivore management programmes and, although a number of hunting effects on population dynamics, body-size distributions and life history in other wildlife have been observed, its effects on life history and demography of large carnivores remain poorly documented.

The concept of Green Infrastructure incorporates social, economic, and environmental benefits: water clearly provides us with all three of these, and is essential to protect. From providing a habitat in its own right to supporting other habitats, from enabling human life to making industry possible, water is crucial for humans and our surrounding ecosystems. The EU’s Water Framework Directive aims to enable sustainable water policy, and Green Infrastructure can play an important role in that by creating structures that support a healthy water cycle so vitally needed water is available to ecosystems and humans alike.

Large marine protected areas (>30,000 km2) have a high profile in marine conservation, yet their contribution to conservation is contested. Assessing the overlap of large marine protected areas with 14,172 species, we found large marine protected areas cover 4.4% of the ocean and at least some portion of the range of 83.3% of the species assessed. Of all species within large marine protected areas, 26.9% had at least 10% of their range represented, and this was projected to increase to 40.1% in 2100.

Aichi Target 11 (AT11), adopted by 193 Parties to the Convention on Biological Diversity (CBD) in 2010, states that protected areas (PAs) must be equitably managed by 2020. However, significant challenges remain in terms of actual implementation of equitable management in PAs. These challenges include, among others, the lack of a standardized approach to assess and monitor social equity and the difficulty of reducing social equity to a series of metrics.
