Effect of changes in the institutional structure of irrigation water property rights on the willingness to pay of farmers for water: case of Tunisia
No full textThis paper assesses the economic value of changes in the attributes of farmers’ irrigation water property rights in Tunisia. Changes on attributes generated by the transfer process of the property rights from the collective to the individual level in addition to changes in “constitutional” attributes were integrated into three scenarios. The valuation was conducted using the Contingent Valuation Method through the elicitation of individuals’ willingness to pay. Results show positive willingness to pay values for all scenarios. However, farmers of the studied region are shown willing to pay more for changes in the constitutional attributes. Furthermore their willingness to pay appears to be most affected by their perceptions concerning the organization and the functioning of the water users’ association to which they belong and by their productivity.Property rights, irrigation water, Contingent Valuation, Resource /Energy Economics and Policy,
Mapping Social Networks for Performance Evaluation of Irrigation Water Management in Dry Areas
No full textCollaboration between actors is an important determinant of water governance, particularly in developing countries suffering from lack of institutional and organizational performances for water management. The objective of this paper is to use the social network (SN) concept in bringing depth to the understanding of local irrigation governance in three irrigated schemes located in dry regions of southern Tunisia. Local stakeholders in the considered schemes interact around different water-related issues. These include authorizations for access to water, extension services for irrigated crops, training on the use of irrigation technologies, and finance and subsidies of irrigation water saving equipment. We considered each of these types of interactions as different tie and we mapped social networks around each of them. Foreach network, actors’ densities, frequencies, and weight were reported. The results were revealing that better performances of water management are observed in areas with high SN density and high centrality of water users’ associations. The relative "weights" of actors in the three considered areas were significantly different, indicating that the application of a standard decentralization process of irrigation water may result in different local organizational arrangements, depending on pat- terns of social interactions
Gestion de l’usage d’une nappe par un groupement d’agriculteurs: l’expérience de Bsissi Oued El Akarit en Tunisie
No full textEn Afrique du Nord, de nombreux aquifères sont surexploités, principalement du fait d’une agriculture irriguée intensive. Cependant, les politiques publiques qui ont cherché à réguler cet usage se sont montrées jusqu’à maintenant peu efficaces, du fait du manque de moyens et parce que les agriculteurs les considèrent comme peu légitimes. L’article analyse un cas de gestion collective de l’usage des eaux souterraines par les agriculteurs eux-mêmes, dans le cadre d’une association au Sud de la Tunisie. Dans la zone de Bsissi Oued El Akarit, l’administration multipliait dans les années 1990 les procédures de contrôle des puits, conduisant à de nombreux conflits. En 1999, les agriculteurs et l’administration se sont mis d’accord pour qu’un groupement de développement agricole soit créé spécifiquement pour contrôler les puits et forages dans cette zone. Depuis, le groupement a effectivement réussi à mettre en œuvre un tel contrôle, mais reste toujours fragile financièrement car il ne s’auto-finance pas. Le processus de concertation qui a conduit à ce dispositif de gestion a réussi grâce à : i) la posture de l’administration, à la fois ferme en matière d’application des lois en vigueurs, et ouverte à la concertation avec les agriculteurs, et ii) aux compétences et à la légitimité des leaders du groupement. Cette expérience montre que, dans certains cas, les agriculteurs peuvent devenir partie prenante d’une cogestion des eaux souterraines pour un usage durable de cette ressource
Biophysical and econometric analysis of adoption of soil and water conservation techniques in the semiarid region of sidi bouzid (Central Tunisia)
No full textSoil and water conservation technologies (SWCT) are important to farmers, to the research community, as well as to the policy makers, given that declining soil health, and increasing erosion and moisture stress have implications for agricultural livelihoods, national food security, and more generally for well-being within rural communities. Yet, despite Tunisia was at forefront of introducing them, the uptake of SWCT by farmers has been less broad than desired. This study aims to identify and analyze those factors that have affected the rate of adoption of SWCT within the Sidi Bouzid governorate of Central Tunisia; a region that is representative of resource-poor environments within the country, and one where land degradation is of both historical and contemporary concern. Employing a binary logistic regression model, with data obtained from a survey of 250 farmers, our results suggest that socio-economic and institutional factors play an important role in the adoption of SWCT. Membership within an agricultural cooperative was positively correlated with adoption. Surprisingly, however, participation in organized trainings for SWCT was negatively correlated with adoption, similarly to livestock holdings. We provide plausible explanations for this counterintuitive finding, together with an argument that conventional processes for knowledge transfer and dissemination are in need of reform
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
No full text“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
