“…Stretching of the cropping calendar has however been observed to increase the probability of drainage problems, which results in increased production costs and/or loss of production and rice quality. In the Office du Niger irrigation scheme, about 40% of farmers are confronted with them (Vandersypen et al 2007b). …”

Increasing irrigation efficiency in irrigation schemes has always been high on the agenda of policy makers. Despite quite some 'social' experiments, whereby large portions of management were carried over to the farmer level, results often remained disappointing. This paper explores why this came about for a case study in the Office du Niger irrigation scheme in Mali. Since Irrigation Management Transfer, farmers are responsible for the tertiary level, but collective action for water management remains below expectations. This paper applies an analytical framework based on the conceptual model developed by van Noordwijk et al. (Conserv Ecol 5:21, 2002) and proceeding in two steps. Firstly, an interview-based stakeholder analysis assesses the objectives and mental models of farmers and the central management regarding water management. It appears from the interviews that the central management wants to increase irrigation efficiency through fully-fledged collective action, whereas farmers value the latter only when it favours easy irrigation. Secondly, the relation between collective action and performance was tested through a field study on a sample of 36 tertiary blocks. Results indicate that only collective action at the inlet of the tertiary canal, currently implemented on less than a third of the tertiary blocks, increases irrigation efficiency (with 14%). Collective action for water allocation is implemented within almost three quarters of tertiary blocks and effectively reduces irrigation problems. However, if they lack the necessary social capital, not all farmers can establish collective action when needed. Based on this analysis, the paper proposes a mix of incentives and measures to resolve the conflict between farmers and the central management to their mutual benefit.

“…In the rice crop season, pre-drainage, such as midseason drainage, will be effective in enhancing root activity and decrease in CH4 production potential in the soil (Furukawa et al, 2008). Also, drainage problems at harvest might have important financial consequences for farmers, both because of increased production costs and of a reduction in rice quantity and quality (Vandersypen et al, 2007). Paddy fields have specific characteristics.…”

“…It was noted by the zone managers that the zone of Molodo is generally considered as the worst performing area. Drainage problems due to excess supply and poor maintenance or absence of drainage canals are common (Vandersypen et al 2007; Aw and Diemer 2005). Due to drainage problems, large sections are inundated and overgrown with weed (Typha sp.).…”

“…Calibrating the biomass production map with field measured rice yields will improve the spatial estimates of rice yields from remote sensing imagery. Vandersypen et al (2007) report that drainage problems at the time of harvest are widespread. Saturated fields induce lower rice quality and loss of production, which may be an explanation for the low H i (0.33) that was found.…”

The irrigation performance of the Office du Niger in Mali, a large-scale rice-based irrigation scheme, was analysed with the use of remote sensing technology. The major advantage of remote sensing derived data over field measured data is that it provides system-wide, spatially distributed and objective information. Four irrigation performance indicators, entirely based on remote sensing, were applied at different organisational levels of the system. The surface energy balance algorithm for land model was applied to high-resolution Landsat images to calculate rice production and water consumption spatially. These maps were used to analyse the productivity of water, the uniformity of water consumption and head-/tail-enders issues at the level of the system, the five administrative zones and smaller management units (casiers). The sustainability of the system was assessed using a long-term time series of the normalised difference vegetation index. The results were discussed and interpreted with the irrigation managers of the Office du Niger. The analysis provided new insights in the performance of the system such as existing head-tail patterns in water consumption and rice yields.
