    Gouverner un territoire de l’eau à partir de considérations sur les savoirs liés à la production du paysage by Jacques-Aristide Perrin

    Published 2019-06-01
    “…Following a study carried out between 2014 and 2017 monitoring operations of ecological continuity in the Dordogne and Têt catchment areas, we analysed the consequences of this type of operation on landscapes and on water uses, which sometimes involve significant modifications in the case of the destruction of hydraulic works. Given how landscape issues are addressed in the implementation of this policy, its current framework does not make it possible to depart from a sector-based management approach focused on biodiversity. …”

    Upstream Flows of Water: from the Lesotho Highlands to Metropolitan South Africa by Yannick Rousselot

    Published 2016-01-01
    “…Coalitions of actors have emerged from these new relations that the transfer has produced, and as such, this project should be analysed as a hydraulic assemblage in which three distinct scales of territorialities are clashing or cooperating with each other: the regional scale, made up of South Africa’s political and economic elites, who seek to direct Southern Africa’s water resources towards the thirsty region in and around Johannesburg; the scale of the Lesotho government, which has a nationalist policy of monopolising any social and spatial stakes for the benefit of the national territory; and the scale of the Maloti communities, which claim their rights as a transnational Basotho nation and autonomy in the face of interventionism from the Lesotho state.…”
