Permanent Mare of Tombo, ©Photo : S. Bachir, IRD In SW Niger, close to Niamey, a detailed hydrological survey has been developed for the last 25 years over 10 000 km2 by the international experiments Hapex Sahel and AMMA. Quality and consistency of these long-term observations allowed assessing the…
Abstract : The mutual influences between human activities and natural resources are at the heart of societal debates. The challenges of water management depend on these interdependences differently according to the local situation. In this context, the hydrology research community is investigating the relevance of its models to represent human…
After a trend of decentralisation of large irrigation schemes management, based on surface water, and of an increasing individual and private use of groundwater use in Turkey, there is a current redeployment of the state in irrigation development, through the planning programme “1000 small-dams in 1000 days” over the country.…
This thesis aims to understand what are the effects of the share of information concerning the agents behavior (theirs extraction) on these latter. We want to compare different methods of providing and sharing information and analyze their effects on the extraction. Key words: Information-sharing, Experimental Economics
Calibration of a conceptual hydrological and distributed model is challenging due to a number of reasons, which include fundamental (model adequacy, identifiability) and algorithmic (e.g.local-search versus global-search) issues.
© National Agency of Dams and Transfers - Hydraulic mission in Algeria, overview of the Chéliff dam involved in the transfer of Mostaganem-Arzew-Oran (MAO). This thesis, in economics and geography, studies the water resources scarcity and water policy in Algeria with a case study of the Macta river…
Drip irrigation is considered the best technique to save water in agriculture. However clogging of drippers is the main cause of loss of water efficiency, especially for small farmers involved in a modernization process. The thesis will be based on an experimental characterization of the biofilm development and microbial activities…
A participatory approach was conducted from 2012 to 2016 with a group of partner farmers organised in Communities of Practice (CoP) in the Office of Niger (ON) zone in Mali.
For thirty years, the French water and sewerage services have been influenced by different managerial models: public service principles, performance indicators (with ambivalence between the influence of New Public Management and of seek for more control), quality management and standardization (ISO 9000, 14000), corporate social responsibility, sustainability. Rather than analysing…
This research investigates the process of land reclamation in the Egyptian desert over the past sixty years.
Channel 900 (West Bekaa) built by the state to distribute water from Lake Karaoun is no longer operational because of the pollution of the lake. It is now used as a reservoir by farmers who bring water from their private boreholes This thesis develops a critical analysis of the…
In a semi-arid environment like Tunisia, irrigation leads to increasing the land value. Many farmers do not own any or enough land to farm. For them, getting an irrigated plot to crop through a land contract is the only solution. Some others have access to land, but do not have…

Drip irrigation technique is considered as the most efficient way to supply crops needs in water and fertilizers. As a recognition to this advantage, this technique contribute in the rapidly expansion of the greenhouse horticulture farming in the Algerian Sahara over the last two decades particularly in Biskra; South-East Algeria.…
Participatory processes for water management are expected to induce learning and could impact on the capabilities' (ala Sen or Nussbaum) distribution among participants, driving sustainability and equity. However it cannot be measured reliably and repeatedly, for diverse conditions. This research aims at proposing, testing on real cases and improving a…

Dans les agrosystèmes méditerranéens, les fossés agricoles et canaux d’irrigation fournissent des services « éco-hydrauliques » reposant sur des interactions entre végétation et processus de transport d’eau, de sédiments et de propagules…

This PhD thesis studies Oasis systems in South-West Algeria. It is focused on a traditional channeling system called Foggara, used for 10 centuries and supposed to provide sustainability to oasis systems in the area. The objective is to analyse the impact of new methods and practices brought by agricultural development…
Summary: Harming consequences of floods in societal systems are the likely consequence of socioeconomic factors. New practices in flood damage prevention have moved away from the implementation of structural measures, embracing as well non-structural measures that integrate ecosystem services, taking advantage of the ecosystems’ potential to prevent, regulate and scale…
