Diverse approaches to learning in rural and development studies: review of the literature from the perspective of action learning

In loosely structured environments such as rural areas, the objectives and methods to encourage knowledge creation and learning are still much debated, leading to a wide diversity of learning systems. Using action-learning theory as a standpoint from which to understand this diversity, a review of the literature was conducted and five specific approaches were identified: (1) extension, (2) community learning, (3) organizational capacity building, (4) empowerment, and (5) social learning. Extension systems and organizational capacity building represent an operational perspective mainly focused on acquiring knowledge and changing practices, through single-loop learning processes. Community learning and empowerment were developed as alternative systems, focusing on changes in values, which can be achieved through double-loop learning. Social learning provides insight into the capacity to influence a wider environment through triple-loop learning, although methods are still rarely formalized. The action-learning perspective enables an understanding of the complementarities between approaches, and thus provides insight into how to devise better learning systems.

Second-home owners and sea-level rise: the case of the Languedoc-Roussillon region (France)

Municipalities of the Languedoc-Roussillon region (South-eastern France) are highly vulnerable to climate-change-induced sea-level rise (SLR) due to their low altitude and the great attractiveness of the region for tourism. This attractiveness has resulted in a very significant development of second homes, which represent half of the housing stock and three quarters of the total capacity for tourism hospitality. In the context of climate change adaptation measures related to SLR, it is imperative to consider the perceptions of second-home owners and their place in local governance arrangements. Scientists advocate the implementation of managed retreat policies to reduce vulnerability by reducing the exposure of buildings, but both the social acceptability and the economic feasibility of these policies are very low. We assume that second-home owners have different perceptions of the risk of inundation and are less involved in the governance mechanisms. It is very difficult to mobilise a large number of owners of small flats who are less concerned with, and less likely to contribute to, policy development, due to their less frequent presence. We studied these issues through a survey in three municipalities, based on a sample of 318 residents and 163 second-home owners faced with inundation risk. We observed a lower sensitivity to risk and a stronger attachment to homes on the part of second-home owners (compared to residents). We also discuss, in terms of equity and efficiency, the impact of their low level of engagement in governance mechanisms.

Assessing aquaculture sustainability: a comparative methodology

Little work dealing with the evaluation of aquaculture system sustainability has so far been undertaken on a global and comparative basis. Moreover, such work is mostly based on very unbalanced approaches in terms of the dimensions of sustainable development that are taken into account. The approach adopted in this article is designed to encompass all the dimensions of sustainability including the institutional one (governance). The taking into account of this latter, in particular, together with the role played by aquaculture in sustainability at the territorial level gives the approach its original and innovative nature. The process of establishing the checklist of sustainability indicators in aquaculture relies on a hierarchical nesting approach which makes it possible to link indicators with general sustainability criteria and principles. At once multidisciplinary and participatory, the approach compares several countries with highly differentiated types of aquaculture system. An original finding from this work is that the technically most intensive farming model scores better than more extensive systems, which might have been thought to be closer to natural systems in their environmental dimension and therefore intuitively more ‘sustainable’. This result suggests relating sustainability outcomes to the level of control and of devolved responsibilities.

Évaluation pluridisciplinaire de la durabilité des pêcheries artisanales autour- des dispositifs de concentration de poissons

Abstract Since fifteen years the introduction of anchored Fish Aggregating Devices (FADs) has been an important component in the development of the small-scale fishery of many tropical island countries. Results however, have not always been as good as expected. In this paper we propose the use of a method to assess the diversity and complexity of changes caused by the FADs on one side, and the sustainability of this innovation process on the other side. The concept of sustainability includes both ecological and socio-economical purposes. The first aims to preserve the resource, the second to secure the innovation process. The assessment framework is based on a grid of twenty-one key parameters of biological, technical, economical and sociological nature. A value ranging from zero to three is given to each parameter according to its effect (no effect, doubtful effect, sustainable effect). An example of this grid is presented by combining experts’ viewpoints in three cases (Comoros, Reunion Island, Vanuatu), which are representative for the diversity of FAD projects. A graphic representation is given for an easier reading of the grid and to improve its use for decision making.

Valuing welfare impacts of climate change in coastal areas: a French case study

Beach protection has become a major issue in reducing coastal risks (erosion and flooding). It is thus advisable to study residents’ preferences for mitigation strategies. Willingness-to-pay (WTP) by permanent and secondary residents for flood protection provided to properties by Languedoc-Roussillon beaches (French Mediterranean coast) is investigated by a contingent valuation study. Results show that WTP is more influenced by risk perception variables than by socio-economic ones. The WTP is then extrapolated on the basis of different adaptation strategies (laissez-faire, managed retreat, denial etc.) which provided information about expected damage associated with sea level rise at the 2100 time horizon.

Dynamics of Research in Aquaculture in North Africa and Support for Sustainable Development and Innovation

ABSTRACT This article examines the supporting role of research in the development of marine aquaculture in the aquaculture-producing countries of North Africa: Algeria, Egypt, Morocco, and Tunisia. Research plays a significant role not only in the support of the development of the sector, but also in the evolution toward sustainable aquaculture practices and a better integrated management of this activity. This analysis was conducted as part of the Aquamed project whose main objective was to create a multi-stakeholder platform (institutional decision makers, producers, researchers, NGOs, etc.) to strengthen cooperation and stimulate innovation for sustainable aquaculture in the Mediterranean. In particular, the Aquamed project aimed at an exploration of forms of collaboration through the identification of sub-groups of countries whose similarity of situations or challenges could help promote dialogue. The study of aquaculture and research in the countries reveals the contrasted situations between Egypt and the three western North African countries (Algeria, Morocco, and Tunisia). The analysis of research capabilities was carried out on the basis of several indicators, which were compiled from a survey among the relevant main institutes in the various countries, as well as from bibliometric research on the publications produced in the field of aquaculture. Beyond the differences identified among the countries, the analysis emphasizes the similarity of the challenges and the benefits of strengthening collaborations on a sub-regional scale.

Evaluation of Aquaculture System Sustainability: A Methodology and Comparative Approaches

Over the last 30 years, aquaculture has experienced an unprecedented development in global animal production with an average yearly growth rate of over 10% between 1980 and 2000 (FAO, 2009). During the same period, capture fisheries saw their progression gradually grind to a standstill and growth stopped from 1995 (total catch fluctuating between 90 and 95 Mt/year according to the year). The growth of aquaculture, despite its benefits and the fact that it is the only way to meet the increase in demand for sea products, evaluated at 270Mt in 2050 (Chevassus au Louis et Lazard, 2009; Wijkstrom, 2003), raises a certain number of issues directly related to its sustainable development. Amongst these are issues related to feed for the farmed organisms, to their biological diversity, to the farms’ economic sustainability, to the impact of aquaculture development on social equity and to the set of arrangements constituting the sector’s governance. Feed, for example, is currently the subject of significant controversy as shown by the emblematic article of Naylor et al. (2000) that exposes the impact on catches of the massive use of fish meal and fish oil in fish and prawn aquaculture and advocates the return to sparser aquaculture systems, directly inspired by traditional Asian systems which use more extensive techniques based on polyculture and fertilisation and where artificial feed is only seen as a potential supplement. This diagnosis, although interesting as it generated much debate, was, however, incomplete and, in fact, inaccurate: by focusing on a single criterion and a single dimension (environmental) of sustainability, the authors were led to make proposals that had no chance of being adopted by the actors. De facto, farming systems have continued to intensify and this has led to a sustained increase in the use of

Resistance to relocation in flood-vulnerable coastal areas: a proposed composite index

ABSTRACT The increasing number of coastal floods in recent years in France has resulted in the design of new adaptation principles for the most endangered coastal areas. The aim of the government is to reduce the vulnerability of these areas by relocating property and infrastructure. These measures have, however, come up against considerable opposition from the population concerned. Using a survey of 421 inhabitants of Hyères, a coastal town in the South of France, this article proposes the study of resistance to relocation through the creation of an index for resistance that incorporates attachment to place, residential mobility and risk perception. The results show a correlation for the index and distance from the sea that highlights the existence of conflicting interests with adaptation measures depending upon population categories. Key policy insights In France, although coastal flooding risk is a key issue in numerous populated coastal areas, coastal dwellers show little willingness to relocate. Resistance to relocation can be assessed through a composite index integrating place attachment, residential mobility and risk perception. Application of such an index shows a correlation between willingness to relocate and distance from the sea. Conflicts of interest with adaptation measures also depend on the age of the dwellers, their standard of living and on home ownership.

Mesurer les impacts des infrastructures de données géographiques (IDG) et des observatoires - Application à l’IDG SIG-LR

Cet article presente les effets economiques generes par l’infrastructure d’information geographique (IDG), SIG-LR situee en Languedoc-Roussillon. A partir de l’analyse de la bibliographie et du fonctionnement des IDG une typologie des effets a ete produite. Une enquete menee aupres de 51 adherents de SIG-LR, a permis de mesurer les principaux effets en termes d’emploi, de gain de productivite et d’economies d’intrants. En outre l’enquete a aussi permis de caracteriser un faisceau d’effets qualitatifs en termes de diversification et de qualite des services rendus, de mise en reseau, de transparence de l’information et d’impacts sur la gouvernance territoriale. Sachant que le budget de SIG-LR est de 0,9 million d’euros on obtient un total d’effets de 3,77 millions soit un ratio d’un euro investi qui produit un impact economique de quatre euros a l’echelle de la communaute des usagers de SIG-LR et de l’economie regionale.

Impact of justice and solidarity variables on the acceptability of managed realignment

Sea-level rise due to climate change will have significant effects on coastal areas and populations. Adaptation policies recommend the managed realignment of the most vulnerable assets and activities. Despite their medium- and long-term benefits, these policies face significant friction due to social acceptability in the communities where they are implemented. This article investigates the hypothesis that respecting principles of justice in the implementation of managed realignment should increase its acceptability. We compare preferences of those people who are exposed to the risk of climate-change-induced flooding and those who are not, as regards funding managed retreat policies and defining compensation criteria for assets at risk. The main theories of social justice provide the four principles included in the analysis: efficiency, need, responsibility and priority assigned to property rights. A choice experiment survey was conducted with 258 residents of coastal and hinterland communities in the south of France. Four attributes were selected to define the managed realignment policy: the dialogue arrangements, the implementation period, the policy implementation schedule and the cost. The results show support for a relatively fast launch of these policies (within 15 years) but in stages and through a process of dialogue with the population. Peoples perceptions of the funding criteria reveal a preference for national solidarity. Finally, national funding of managed retreat policies and compensation criteria based on market prices have a significant positive influence on the acceptability of managed realignment policies, whereas introducing responsibility-based compensation criteria tends to favour the status quo over the adaptation policy. Policy relevance Prioritization of the funding criteria reveals the preference for national solidarity. Preferences for the justice criteria underpinning compensation reveal a great diversity of values. Besides implantation modalities, preferences for managed realignment policies depend on which level they are implemented at, on the expropriation criteria (the emphasis given to property rights, i.e. market price), on the attachment (people perceived as worst off, i.e. the property is their main residence rather than a second home or they have lower levels of income) and on the degree of responsibility (related to the date of purchase, i.e. on the information given at the time on the risk).
