Type of session: Speed Talk Session


The food security agenda is gaining in importance as an increasing number of arenas are putting it in under the spotlight. At the same time in other arenas water management and conservation remains a key issue for developing a sustainable future. Additional trends including climate change, demographic and economic growth, local food production, and conditions for international trade, modify the connections between these issues. We assume here that land use choices are the key drivers of these connections, making them more or less compatible, with consequences on resilience of socio-ecosystems. A substantial integrated analysis of this land, food and water nexus has still to be made, building on already existing de facto arrangements around the world.


Some of these existing arrangements have long histories while others have been rapidly adapting to changes in their environment. Their analysis should obviously include direct linkages, such as water as a required resource for food production, or the need for energy. But it should also include the trade-offs with other ecosystem services, or trade-offs between a market-based system built on local competitive advantages and the need for autonomy for these essential goods (i.e. a low dependency to imports of these goods). Frameworks based on balances, such as the calculation of footprints (or virtual rescources), constitute an interesting starting point, to which we need to add an analysis of system dynamics and inclusion of political strategic choices.


The purpose of the session is to acknowledge the diversity of these arrangements, as well as to build upon an understanding of them to provide the keys to fine tune suitable arrangements in other places. We assume that this diversity can be explained by factors associated with local conditions, including local social choices. Comparison of cases should enable as unpacking of the interactions between entities at stake.


The session will be composed of presentations with a common format in order to detail such arrangements, compare them, learn about existing diversity, and further propose a common framework to describe new case studies at a scale that “makes sense” for the people within them. Cases will be compared according to the resulting fragility of land-water-food systems, the contribution to needs at larger scales or the level of their autonomy. The session will also build on outcomes of previous sessions on agriculture and sense of place. The ultimate goal is to identify strengths and barriers to resilience of these socio-ecological systems due to existing arrangements, in order to inform research and policy arenas related to food security and water management.


Speakers will agree prior to the session on a common framework of description of the arrangements they will describe. This framework should include the elementary components and dynamics required to understand the cases, as well as typical scenarios to assess their contribution to resilience. The session will start with a quick presentation of this common framework, followed by the presentation of cases. Discussion will then build on the comparison of cases in order to propose a generic description of land-food-water arrangements. The descriptive framework will serve as a backbone to the session, and a boundary object among participants. At the end of session we aim to publish a revised version of the framework and case studies as a collective academic paper.


Program overview

The session will commence with a short introduction of the common framework then a presentation of the 5 following case studies, Other participants in the session will then be more than welcome to contribute with their own examples.

- Walmadany in Kimberley, Australia (A. Poelina, Ph Vaillant)

- Kongulai Water Supply Catchment, Guadalcanal, Solomon Islands (I. White, I. Lekelallu)

- Tensions between independent water access, benefits from ecosystem services and agricultural production in Thau basin, France (O. Barreteau, A. Richard-Ferroudji, G. Abrami)

- Symbiosis or exploitation? Assessing the Ramifications of Rural-Urban Water Transfers in Tamil Nadu, India (S. P. Gnanasekaran, T. Clark)

- Tana Delta in Kenya (S. Duvail)
