Towards biodiversity-based livestock systems: review of evidence and options for improvement

A major challenge for livestock farming systems (LFSs) is to reconcile production with the management of natural resources, especially biodiversity and ecosystem services. Based on a review of research conducted on grassland- and rangeland-based LFSs, this paper addresses this challenge by analysing biodiversity as a product of and a key resource for LFSs. Although most studies reveal antagonisms between biodiversity and production, our findings show that it is possible to move towards synergies. The literature review sheds light on five points: (i) moving beyond an antagonistic view of biodiversity and production by considering biodiversity as a resource requires new criteria for biodiversity categorization from a taxonomic view to a functional one; (ii) functional biodiversity (both domestic and wild) considered as a resource provides beneficial properties (e.g. stability and resilience) to LFSs; (iii) links between production and biodiversity cannot be simply summarized as having a negative impact of production intensity as management practices have various impacts on the different components of biodiversity; (iv) impact assessment studies linking management of LFSs and biodiversity reveal complex multi-level interactions between grassland or rangeland management and biodiversity; (v) a large range of management options are available to move towards biodiversitybased LFSs. We conclude that future research should address the challenge of collective management of wild biodiversity at higher levels of organization (landscapes, territories, etc.) and that such collective management would greatly benefit from the experience of domestic biodiversity.

Mutual learning between researchers and farmers during implementation of scientific principles for sustainable development: the case of biodiversity-based agriculture

A part of scientific knowledge that aims to promote sustainable development consists in management principles of complex systems. Its implementation requires a precise understanding of the situation of action and of the actors’ involvement in the situation. It can no longer be thought of in terms of transfer. Successful implementation relies on changing the ways of understanding and valuing the local context, as well as the actors’ practices. Transdisciplinary approaches are proposed to facilitate mutual learning between researchers and local actors that lead to a better understanding of the action situation. We explore the benefits of such approaches and their implications for those involved in the field of agroecology. Agroecology is based on the implementation of scientific principles that aim to make agriculture more sustainable. These include the creation of agricultural production based on biodiversity. Analysis of three case studies concerning the biodiversification of forage production shows that implementation is not getting farmers involved in the researcher’s project, but rather that researcher’s intentions find a place in the farmer’s projects. Researchers adapt their scientific production to the farmer’s needs while farmers review their goals and means as a result of these interactions. The result is a better understanding of the situation to be transformed by both researchers and farmers. This new insight justifies making implementation an integral part of the scientific approach. However, both researchers and farmers committed to the situation need to be ready to leave their comfort zone.

How the development of products valorizing local breeds changes breeding goals: examples from French cattle breeds

A way of making local breeds more sustainable is to promote their products through individual or collective initiatives. Those initiatives can induce new points of view on the breed and lead to discussions or even tensions between stakeholders. We illustrate this statement with examples of French cattle breeds. Several kinds of changes in breeding goals are described in this paper, with the appearance of new challenges and/or new stakeholders linked to the development of strategies to add value to the breed. Then the several ways in which those changes occurred are explained. The situations analysed show configurations with easy consensus to build as well as situations of conflicts. Those case studies highlight the importance of the existence of arenas where the diverse points of view can be expressed. The role of the breed associations is then essential, but remains complex as, in some cases, breeding goals are strongly discussed. The question of the orientation of the breed then becomes a key question when initiatives to add value to local breeds are taken. New choices of add value generally have important consequences on the definition of breeding goals.

Managing local breeds: a dynamic connected to livestock farming systems that concerns different levels of organization

Management of local breeds is closely linked to the global challenges involved in genetic resources management. However, it cannot be reduced to this genetic dimension alone and is an integral part of the entire farming system of which it is a part. The aim of this paper is to show why it is essential to have an approach to local breed management that takes the dynamics of livestock farming systems (LFS) into account. After a presentation of the LFS approach, we show how genetic management is strongly linked to other dimensions of farming systems, at the farm scale as well as at more comprehensive scales. We illustrate our claim with different examples of the management of local breeds of different species.

No Development, No Conservation: Elements from the Conservation of Farm Animal Genetic Resources

Using concrete examples of conservation of farm animal genetic resources, we show that conservation and development should not be considered as two opposing processes. On the contrary, their synergies can facilitate conservation dynamics. We discuss conservation and development dynamics, and provide examples of synergies between the two dynamics to underline how development dynamics can help conservation programs.

Challenges for local breed management in Mediterranean dairy sheep farming: insights from Central Greece

Local breeds are recognized as an important element for the maintenance of various and specific farming systems. Challenges for local breeds’ management, in a context of crossbreeding with exotic highly productive breeds, have been mainly studied in tropical countries. However, similar situation and challenges are likely to exist in Mediterranean countries subjected to climatic and feed scarcity issues. The objective of this work is to identify the challenges for local breed management in a regional context of informal crossbreeding with highly productive breeds. For this purpose, the case of dairy sheep farming in the region of Thessaly, in Central Greece, was examined. Semi-structured interviews were performed in 46 farms and processed through hierarchical classification on principal components. A follow-up on seven farms raising the Karagouniko sheep breed, the main local breed of the region, was carried on during one milk campaign. Results showed that a diversity of breeding strategies involving local purebred and crossbred flocks coexist in the region. The Karagouniko breed is facing several challenges. The supply in exotic breeding males and their crosses could be wide-scaled and involved a diversity of operators, whereas the supply in breeding males of Karagouniko breed was restrained to between-farm supply among flocks under milk recording scheme. In addition, the heterogeneity of access and quality of collective rangelands affected the farming of Karagouniko breed ewes, whose purebred flocks were significantly associated with the grazing on native grasslands. Finally, unfavorable dairies’ policies led Karagouniko farmers to seek higher flock milk production through levers that could impact the vulnerability of the farm, such as earlier lambing period or earlier weaning age. Farmers also questioned the use of highly productive breeds as a potential lever to reach higher flock milk production.
