INRAE, CIRAD and IRD joint scientific contribution - Growing biodiversity together

Scientists from CIRAD, INRAE and IRD are delivering key messages in the fight against biodiversity loss. Already raised at the 2021 IUCN World Conservation Congress in Marseille, this is a joint contribution in anticipation of the phase 2 of COP15 on biodiversity, to be held in the autumn.

COP15 biodiversity, a global framework for the next decade

The Fifteenth meeting of the Conference of the Parties (COP15) on Biological Diversity is held in two parts: the first one took place on October 2021 in Kunming, China, with a high-level segment and the declaration "Towards an Ecological Civilisation", and the second will take place in autumn 2022.

Main objective: To adopt the new global biodiversity framework, which sets targets to be achieved by 2030 to reverse the current trend of biodiversity loss.

This new framework follows on from the 2011-2020 strategic plan for biological diversity, adopted in Nagoya at COP10 in Japan and setting 20 Aïchi targets, which have not been met. The new framework aims in particular to tackle the issues of nutrition, food security, health and the livelihoods of the most vulnerable communities.

The new global biodiversity framework, which will be formally adopted at COP15, aims to protect 30% of land and oceans by 2030. In 2022, according to Protected Planet, protected areas cover 16% of land surface (17% with conservation areas) and 8% of sea surface. 

Achieving the 30% goal is inextricably linked to global food security and health issues. Indeed, the surface area concerned will necessarily involve areas cultivated and managed by humans, which are themselves dependent on biodiversity. Based on the ecological interactions between agriculture and natural biodiversity, the authors of this joint proposal, call for the integration of local practices and knowledge to renew agricultural approaches in the developed and developing world, in order to co-construct a new relationship with nature with all stakeholders and for the well-being of all human beings.

Joining hands with natural biodiversity to enable agriculture to adapt to a changing environment

Biodiversity must become a priority for global agriculture, which can rely on agroecological practices or mixed management methods combining intensive activity areas and preserved natural areas. Its management methods must make the most of scientific and local knowledge to characterise and understand the functions of biodiversity and ecosystem services, while integrating combinations of conservation approaches. The authors point out that exchanges between natural and cultivated environments have been successful. Indeed, they have enabled the adaptation of maize to high altitudes in Mexico and millet to Sahelian climates through crossbreeding with wild relatives.

Agricultural and food systems benefit from the services provided by local natural environments

Natural environments also provide important ecosystem services for agriculture, such as pollination. Good management of ecological interactions at the local landscape scale can thus help to develop more resilient agriculture. As for soil biodiversity, it is a determining factor in the closing of the carbon, nitrogen, phosphorus and water cycles.

Taking better account of the role and knowledge of local stakeholders

Traditional agricultural and food systems are particularly rich in biodiversity.  A better understanding of them is therefore essential to build agricultural and food systems that are resilient in the face of climate change, based on local, protected and valued resources. The knowledge of farmers and local communities must be incorporated more into scientific knowledge and decision-making in order to jointly come up with other forms of managing agricultural biodiversity, while ensuring the integration of its wild counterpart.

Biodiversity and services provided by nature: what is known about the impact of pesticides?

To what extent are birds, insects and other living organisms affected by pesticides? What is the effect of these substances on services as essential as pollination or biological pest control? A collective scientific expertise by INRAE and Ifremer provides updated information on the impact of plant protection products on biodiversity and on the services that ecosystems provide to society. It identifies ways to reduce them. The result of two years’ work by a multidisciplinary group, it was carried out at the request of the French ministries in charge of the Environment, Agriculture and Research, and covered all environments: atmospheric, terrestrial, continental and marine aquatic environments.

Press report - Putting biodiversity at the heart of INRAE's research: from diagnostics to solutions

PRESS REPORT - Biodiversity has turned out to be essential to the resilience of ecosystems, food security and health. As a valued inheritance and a common good, it must be protected and restored both for its own sake and for the ecosystem services that depend on it. Beyond the current and immediate erosion of biodiversity, there is also a growing tendency towards uniformity. This is the visible consequence of numerous pressures, but it is particularly linked to human activities and the impacts are, in some instances, further exacerbated by climate change. INRAE’s scientists are working to understand the dynamics of biodiversity and the functions it supports in many ecosystems (including agroecosystems, forests and woodland, lakes and rivers, mountain ranges). They work with local stakeholders to co-design and implement nature-based solutions and to devise ways to halt the erosion of biodiversity and encourage its recovery.

Crop diversification enhances yields, biodiversity and ecosystem services

PRESS RELEASE - This is the outcome of a large-scale synthesis review conducted by a Franco-Dutch research team, including a compilation of the results of 95 meta-analyses, 5,156 studies and 54,554 experiments spanning 85 years and representing more than 120 crop species in 85 countries. Crop diversification was found to enhance crop production by 14% and associated biodiversity by almost 25%. Water quality was improved by 50%, pest and disease control by over 63% and soil quality by 11%. The authors—scientists from CIRAD, INRAE and VU University Amsterdam—distinguished between the diversification strategies implemented, while highlighting the excellent performance of agroforestry-based systems.
