L’eau d’irrigation est une ressource cruciale pour le développement économique et social en Tunisie. Dans un contexte de décentralisation et de délégation du rôle de l’État, une part importante de la gestion de cette eau d’irrigation a été confiée aux groupements de développement agricole (GDA). Ces groupements souffrent cependant d’un manque de reconnaissance de la part des usagers, qui se manifeste essentiellement par un faible consentement de leur part à payer les redevances.
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.
The world’s population is likely to reach 9 billion by the middle of this century. The Food and Agriculture Organization of the United Nations (FAO) believes that 60 per cent more food will be needed by 2050 to sustain all these people. Where possible, this food should be produced where it is needed – in developing countries.
Feeding the world’s steadily growing population while respecting the planetary boundaries will be a key challenge for humanity in the future. Prevailing production and consumption patterns are leading to a loss of natural resources and destroying ecosystems and their functions. More than 820 million people were affected by malnutrition in 2017. Climate change is exacerbating this development and pushing natural ecosystems to their limits, something that is having far-reaching consequences for the environment, the economy and humanity.
La population mondiale atteindra probablement les neuf milliards de personnes d’ici le milieu du siècle. Selon les estimations de l’Organisation des Nations unies pour l’alimentation et l’agriculture (FAO), il faudrait augmenter la production alimentaire de 60 pour cent pour les nourrir. Ces produits alimentaires supplémentaires devraient dans l’idéal être produits là où ils sont censés être consommés, c’està-dire dans les pays en développement. Pour y parvenir, ces pays doivent augmenter sensiblement leur production.
Sustainability is GIZ’s guiding principle and forms the basis for our contributions to shaping a society that is fit for the future. We compile and analyse all the most important climate and environmental data every year to gain a better understanding of our environmental sustainability and continuously improve our performance. Externally validated information about our activities in Germany is provided by the Eco-Management and Audit Scheme (EMAS).
Disasters are increasing worldwide, with more devastating effects than ever before. While the absolute number of disasters around the world has almost doubled since the 1980s, the average number of natural disasters in Middle East and North Africa (MNA) has almost tripled over the same period of time. In the MNA, the interplay of natural disasters, rapid urbanization, water scarcity, and climate change has emerged as a serious challenge for policy and planning.
The aim of this paper is to propose an innovative operational framework that couples life cycle assessment (LCA) and a participatory approach to overcome these issues. The first step was to conduct a progressive participatory diagnosis of the socio-ecological structure of the rural territory and to characterise the main cropping systems. The results of the diagnosis and other data were progressively triangulated, validated and consolidated with the stakeholders at the territorial level. The paper discusses the quality and validity of data obtained using a participatory approach.
The “Partnerships for Improving Pastoral Policies” PIPP project has as its objective to update the Tunisian pastoral law and / or to develop a pastoral code. The approach involves multiple institutional levels that include local communities, national governments and international actors. The engagement of different stakeholders in the negotiation process is recognized and fostered. Furthermore, the approach aims to develop capacities of stakeholders involved.
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.
