L’érosion hydrique est une préoccupation agronomique, économique et environnementale importante en milieu semi-aride méditerranéen. Le choix de la méthode pour l’estimer dépend des données disponibles et des conditions de la zone d’étude. Cet article vise à quantifier et spatialiser l’érosion hydrique en utilisant l’équation universelle des pertes en sol (Universal Soil Loss Equation [USLE]) dans ses versions modifiée (Modified − MUSLE) et révisée (Revised − RUSLE) et couplées à un Système d’information géographique (SIG) : MUSLE-SIG et RUSLE-SIG.
This study established physicochemical and sensory characteristics of virgin olive oils (VOOs) and linked them to consumers’ liking using external preference mapping. We used five Tunisian and two foreign VOO varieties produced by two processing systems: discontinuous (sp) and continuous three-phase decanter (3p). The samples were analyzed and evaluated by a panel of 274 consumers. The external preference mapping revealed five VOO clusters with a consumer preference scores rating from 40% to 65%.
Dans un contexte de rareté de l'eau, les pays de l’Afrique du Nord Ouest (NWA) consomment 70% de leurs ressources en eau renouvelables. La surexploitation des eaux souterraines, estimée à près de 50%, est devenue un défi majeur pour la conception et la mise en oeuvre de politiques durables d'allocation et de gestion de l'eau dans la région. Cette situation menace l'avenir de l'irrigation, où la contribution des eaux souterraines est déterminante : 100 % en Libye, 68 % en Tunisie, 54 % en Algérie.
This manual provides a set of conceptual definitions and practical implementation protocols for knowledge and scaling hubs. Both concepts of knowledge and scaling hubs are developed to aggregate, leverage, and coordinate the efforts undertaken by pilot research project with larger development programs and local scaling dynamics.
The objective of this paper is to analyse the olive oil value chain (OVC) in the Governorate of Medenine (south-east of Tunisia) and the relationships between its main operators for an effective involvement and better performance and resilience of olive sector. Based on semi structured interviews and participatory multi-stakeholders’ workshops, OVC has been analysed and described. MACTOR approach has been applied to establish linkages among chain operators and activities in a partnership approach.
Providing farmers with essential agricultural information and training in the era of COVID-19 has been a challenge that has prompted a renewed interest in digital extension services. There is a distinct gender gap, however, between men’s and women’s access to, use of, and ability to benefit from information and communication technologies (ICTs).
This event launches a new phase of the JP RWEE that will even further enhance its holistic approach to advancing rural women’s economic empowerment by integrating a climate resilience lens to tackle deep rooted social norms which limit women’s participation and leadership in rural communities including through applying gender transformative approaches.
This case study presents an analysis undertaken for the IFAD-funded Agropastoral Value Chains Project in the Governorate of Médenine, Tunisia. High-resolution imagery makes it possible to track the development of roads, buildings, irrigation schemes, and other types of investments. Over 140 km of road constructed or rehabilitated by the project are easily detectable on satellite imagery.
This regional workshop was designed to strengthen the capabilities of representatives of NIFUs for analyzing the situations of their NAIS, and to use their national experiences to identify strengths, weaknesses, and threats/challenges affecting seven key areas influencing development of NAIS, namely: (i) strategy/policy, (ii) institutional aspects, (iii) stakeholders, (iv) content, (v) people, (vi) infrastructure, and (vii) financial aspects. Possible solutions for the key weaknesses and threats /challenges were defined by participants.
Le principal défi des systèmes alimentaires africains à l’avenir sera de fournir de la nourriture à une population en croissance rapide dont les régimes alimentaires et les préférences alimentaires évoluent. Alors que la population européenne diminue, les consommateurs exigeant des aliments produits de manière écologiquement et socialement responsable, la population africaine va plus que doubler entre 2020 et 2050, la demande alimentaire augmentant encore plus en raison des changements alimentaires.
