Sustainability Consulting – International Cooperation Authors: Stéphane Baudé,

Since the popularisation of the work of Elinor Ostrom, winner of the Nobel Prize in Economics in 2009, the rediscovery of the Commons as a mode of sustainable management of natural resources (i.e., modes of management of a resource by the community of its users, which defines rules for allocation and use of the resource, aiming to guarantee its availability and sustainability) has opened up new av. [...] The objectives of the fishing rules are to ensure the reproduction of the resource by protecting the key moments of the reproductive cycle, in order to ensure that the economic interests of different human groups settled along the plain are taken into account equitably, and to regulate the distribution of fishery products within domestic units. [...] The terms of reference ratify the limits of the zone, the rules of use, detail the organisation of the zone's management bodies, and provide for sanctions in the event of non- compliance with the rules. [...] From the 1980s onwards, the extension of cultivated areas, the increase in the number of herds, and the new importance of fishing in the marshlands led to the overlapping of agricultural uses, pastoral uses, and fisheries. [...] This fluidity in the modes of coordination between farmers and stockbreeders was the basis for the spatiotemporal reorganisation of agricultural and pastoral activities under the effect of changes in the environment, the densification of the plot of land, and the increase in the number of herds.
