Small-scale irrigation initiatives are expanding rapidly in Burkina Faso. However, in many cases optimal yields are not being obtained despite the available water and the required nutrient applications. Local stakeholders need an easy-to-use decision-support tool to assess irrigation water use and its impact on yield. In this study, a water-driven crop model, AquaCrop, developed by FAO, was adapted for cabbage (Brassica oleracea L.) using a limited dataset and leave-one-out cross-validation (LOOCV). The experiment was conducted in south-western Burkina Faso on small irrigated farmer plots, where optimal managerial conditions could not always be guaranteed. Statistical indicators – normalized root mean square error (nRMSE) and index of agreement (d) – suggested that the model is very reliable for simulating cabbage biomass yield and soil water content (low nRMSE and d-index near 1). The relationship between observed and simulated yield produced a d-index of 0.99 and an nRMSE of 1.39% (or 0.59 ton/ha). The comparison between observed and modeled soil water content gave a d-index of 0.90 and an nRMSE of 4.38% (or 9.13 mm). Also of interest was the indirect link between plant density and yield via maximum canopy cover, which can considerably simplify yield estimation. It was concluded that AquaCrop was a very useful tool for enabling local end-users to evaluate and optimize cabbage yield and irrigation water use. [less ▲]

In recent decades, the Kou watershed in south-western Burkina Faso has suffered from poor water management. Despite the abundance of water, most water users regularly face water shortages because of the increase in the amount of land under irrigation. To help them achieve a more equitable allocation of irrigated land, local stakeholders need an easily managed low-cost tool for monitoring and mapping these irrigated zones. The aim of this study was to develop a fast and low-cost procedure for mosaicing and georeferencing amateur small-scale aerial photographs for land-use surveys. Sets of tens (2009) and hundreds (2007) of low-altitude aerial photographs, with a resolution of 0.4 m and 0.8 m, respectively, were used to create a detailed land-cover map of typical African small-scale irrigated agriculture. A commercially available stitching tool and GIS allowed georeferenced ‘mono-images’ to be constructed; both mosaics were warped on a high-resolution SPOT image with a horizontal root mean square error (RMSE) of about 11 m. The RMSE between the two image datasets was 2 m. This approach is less sensitive to atmospheric conditions that are non-predictable in programming satellite imagery. [less ▲]

The Kou watershed in south-western Burkina Faso has suffered from poor water management for several decades. Covering 1,800 km², this small watershed is the site of the second largest city in Burkina Faso (Bobo-Dioulasso), a former State-run irrigated rice scheme and several informal agricultural zones. Notwithstanding the abundance of water resources, most water users regularly face water shortages due to a population increase and low irrigation inefficiency. Local stakeholders therefore need low-cost, easy-to-use decision-support tools to enable them to monitor and exploit the water resources to best advantage at different spatial and user levels. A top to bottom series of adapted water management tools has been successfully installed to address current problems, from watershed level (top) to individual field level (bottom), and including the 1,200 ha irrigated rice scheme. Remote sensing techniques have been developed to map the agricultural lands. Combined with data from a network of hydrologic gauging stations, regional water-use maps have been compiled. SIMIS software is being used for the public-private management of the irrigated rice scheme. A simple field-crop-water balance model, AquaCrop, is being used by extension workers to draft optimal irrigation charts. Day to day water use on irrigated plots was monitored by soil humidity and crop canopy measurements. Each water management tool is applied independently, requiring only limited data, but their combined results are contributing to improved integrated water management. [less ▲]

Within the framework of a national policy on food sufficiency dating back to the late 1960s, a 1,200 ha State-run irrigated rice scheme, called the ‘Kou Valley’ scheme, was established in south-western Burkina Faso. Jointly managed over a long period by State officials and a series of international development agencies, all aid ended abruptly in 1993, leaving the farmers and their hastily assembled Water Users Association (WUA) poorly prepared to assume management of the scheme. Concerned about the poor state of the water management and aware of their lack of management skills, the WUA turned to a private external operator for support via a public-private partnership (PPP), which involved outsourcing the water management. Initially, the PPP was funded and assisted by an international development agency. The costs are now gradually being met by the WUA and will ultimately represent 12% of the water fees collected from WUA members. An irrigation advisor was appointed on a full-time basis, and technical studies were conducted to assess the water management problems and put forward viable solutions using decision-support tools (SIMIS). At various stages, participatory meetings were organised to enable the farmers to express their opinions and to propose and discuss possible solutions. After 3 years, there was some improvement in the land occupation situation and the water distribution was more equitable in some parts, as shown by various performance indicators and a general survey. However there are limits to what water management change alone can achieve without essential infrastructural improvements. As the WUA members lacked the necessary education, effective knowledge transfer was not possible and therefore assistance on water management is likely to remain in private or State hands. The farmers, however, have indicated their satisfaction with the proposed approach and their willingness to participate in PPP-based management of the scheme. [less ▲]

The Kou watershed is characterized by important water resources used for drinking, agriculture (especially in the important irrigated areas), industry and the preservation of aquatic fauna and flora. For several decades there has been increasing pressure on the Kou’s water resources, partly because of the expansion of the irrigated agricultural areas. This study was conducted to examine this issue, focusing on one specific irrigated area. In order to monitor the expansion of irrigated areas in developing countries, a low-cost remote sensing method based on Landsat images and aerial photographs was developed. The method is based on maximum-likelihood classifications, followed by backward and forward change detection analysis requiring agronomic expertise. Using pixel trajectory analysis, the method connects all pixels to their consecutive states in order to correct their current states. The study showed that the irrigated area has expanded by almost 80% over 20 years, with most of this expansion occurring in the past 10 years. The approach, if validated, could be used to obtain information on past occupation in the rural irrigated areas for which there is no archived data. [less ▲]

Water is a priceless natural resource very sensitive to external factors and environmental degradation. It becomes more valuable as competing uses multiply. Therefore, integrated and cooperative water resources management is essential within a watershed. The Kou watershed (Burkina Faso) has significant water resources which are divided between domestic (water supply, etc.), agricultural (irrigation) and industrial uses. The hydro-agricultural context of the Kou watershed is marked by a perennial river, along which are located several agricultural areas. Over time, once satisfying water needs degraded to irrigation water deficits, mainly due to a reduction in water supply and an increase in irrigated farmland. Irrigation water deficits are mostly encountered in the more downstream agricultural areas. The socio-economic context is characterized by a growing trend for highly profitable and water consuming crops (e.g. banana). This further increases the irrigation water deficits, as well as the upstream-downstream water-sharing inequalities. In the context of the study area, the main factor that may influence the agricultural water withdrawals is the farmers' production system. The main hypothesis of the study was to verify whether these agricultural production systems could be the lever to optimize irrigation water use. The methodology of the study was to provide a sufficiently accurate knowledge of the water management system, so that improvements could be proposed. A decision support tool based on the ‘multi-agent systems’ approach (MAS) was developed in order to provide an answer to the problems of the study area’s water management by simulating management scenarios. The findings of the study showed (using the MAS tool) that through actions on agricultural production systems it is possible to optimize irrigation water withdrawals. Within the production systems, it is mainly changes in irrigation practices that have led to an optimization of the water management. Finally, the study showed that the use of MAS in resolving agricultural water management issues in the Kou watershed could be the starting point for a new approach in water management. This approach allows the effective integration of the consequences of farmers' decisions regarding water management. More generally MAS-based natural resources management tools provide a common representation of the environment within a model that can help raise awareness concerning a better management of these natural resources.

The Kou watershed is a geographical space having important water resources, whose are used between: drinking water supply of Bobo-Dioulasso city (Burkina-Faso’s second most important city) and surrounding localities; agriculture through very important irrigated surfaces; industry; fauna and flora preservation, through a minimal sanitary debit guaranteed. Since some decades, one observes more and more increased pressure on Kou water resources. From an agricultural point of view, a comparative visual observation of irrigated surfaces during the years 1980 and during years 2000 shows an increase of surfaces. It would be then appropriate to establish a potential of irrigation of the set of available water resources in order to estimate maximal irrigable surfaces by water resources. Thus, this study has for goal the evaluation of Kou watershed irrigated zones surface, with the help of remote sensing. In order to facilitate irrigated zones detection, the study will focused on the period between January and June, where all cultures are irrigated with Kou watershed surface water and/or groundwater. The chosen methodology is images classification in order to extract irrigated zones surface. We had for this study a set of images and various data: Landsat-4 TM, Landsat-5 TM, Landsat-7 ETM+, SPOT 5, aerial views, agro meteorological data, cartographic data (GIS), data investigation reports, etc. Because of images various origins, we conducted images pretreatment that essentially consisted in image reflectance calibration. This operation appears to be indispensable when working with images from coming different sensors. Classification methods that we used are: a maximum likelihood classification, then a decision tree classification applied to images for which vegetation index (NDVI) has been calculated. The later classification method has been introduced in order to permit a better discrimination between natural vegetation and crops which can often react in similar spectral ranges. This method is based on threshold detection of vegetation classes. Classification methods used allowed us to estimate until a certain point irrigated surfaces, without having, however, a finer information. With 30 m spatial resolution images covering a survey zone with "reduced" to "mean" agricultural lands size, it is sometimes enough difficult to discern natural vegetation pixels from crop pixels. So, we should have considered mixed classes of pixels that strongly skewed our final results. The overall accuracy of our classifications are between 70% and 90%, with Kappa coefficients between 0.4 and 0.85. These Kappa coefficients our results between "tolerable" and "good". However, our evaluations seem to be near enough of those gotten by the means of hydro agricultural inventories led on the same zone. The committed mistakes remain in an interval of +/-20%. [less ▲]

Situé au Sud-ouest du Burkina Faso, d’une superficie de 1.823 km², le bassin versant du Kou, avec ses importantes ressources en eau, fait l’objet d’une exploitation intensive de ses réserves (alimentation en eau potable, irrigation des zones agricoles, ...). Face à la croissance démographique, l’élaboration d’un état de lieux des ressources en eau s’avère indispensable. L’objectif de cette étude est la réalisation d’un bilan d’eau du bassin versant du Kou et s’inscrit dans le cadre d’un travail de recherche contribuant à l’amélioration de la connaissance, de la gestion et de la protection des ressources en eau pour l’agriculture. Cela a nécessité l’utilisation du modèle hydrologique HYSIM. La mise en œuvre de ce modèle, réalisée sur une année hydrologique (année 2000), et particulièrement sur le sous bassin versant en amont de Badara a révélé la relative complexité de ce bassin versant due à la présence de nombreux processus hydrologiques actifs en son sein: ruissellement de surface, contribution de la nappe aux débits d’écoulement, précipitations, évapotranspiration, infiltration. Les résultats obtenus sont satisfaisants et indiquent que pour un apport d’eau annuel de 1027,7 mm, à l’exutoire 57% provient de la pluie et 43% provient de la nappe, à travers le bassin 77% (863,8 mm) est perdu par évapotranspiration, 13% (151,5 mm) participe au ruissellement de surface et 10% (112 ,4 mm) s’infiltre.

Le bassin du Kou, situé dans le sud-ouest du Burkina Faso, est depuis quelques décennies le théâtre de différentes formes de conflits liés à toute une série de problèmes que l’on rencontre généralement dans des zones irriguées. Dans le bassin du Kou, les aménagements hydroagricoles recensés couvrent une superficie totale de près de 3.200 ha. Il s’agit pour l’essentiel de périmètres privés formant la ceinture maraîchère, horticole et fruitière de Bobo-Dioulasso et d’un grand périmètre de 1.200 ha réalisé par l’Etat à Bama et spécialisé dans la production du riz. Outre l’abondance en eau liée à la présence de sources importantes, d’une nappe phréatique facilement exploitable, d’un cours d’eau pérenne et un hivernage à caractère sub-humide, la plupart des utilisateurs d’eau se retrouvent régulièrement en pénurie d’eau à cause d’une augmentation de la population et d’une intensification de l’agriculture irriguée. Ceci conduit les gestionnaires du bassin à rechercher des outils de contrôle et de suivi. [less ▲]

Cette étude consiste à trouver un modèle de prévision de la production de coton dans la rovince du Houet d’une part, mais également de tenter d’évaluer la sensibilité de la méthode vis-à-vis des données nécessaires à cette prévision. Celles-ci sont de trois types : des données météorologiques, des données NDVI et des données agro-météorologiques. Ces facteurs sont issus d’une série de logiciels : VAST, AgroMetShell, WinDisp et Statistica. Plusieurs modèles de prévision ont été construits, et mettent en évidence une bonne corrélation entre certaines variables explicatives et les données de rendements du coton dans la province du Houet. Le meilleur modèle trouvé se caractérise par un coefficient de détermination (R²) de 0.75 et une erreur-type de 73 kg/hectare, ce qui représente une erreur d’environ 6.5%. Ce modèle retenu fait appel à seulement 4 variables d’entrée faciles à obtenir. [less ▲]

En Mai 2007, un recensement hydro-agricole du bassin du Kou a été organisé par le projet et l’AEDE, et effectué par les agents de la Direction Provinciale de l’Agriculture, de l’Hydraulique et des Ressources Halieutiques. Les compétences en appui-conseil sur le terrain de la DPAHRH-Houet ainsi que la confiance dont profitent ses encadreurs dans le milieu agricole étaient indispensables pour le bon déroulement des enquêtes. L’AEDE et le projet ont assumé les besoins en formation et en matériel au niveau de la DPAHRH. Le traitement des enquêtes a été fait par le projet, les résultats et la base de données résultante ont été restitués au niveau de l’administration. Pour les différentes zones agricoles du bassin du Kou, les données suivantes ont été recensées par exploitant : données d’identification & coordonnées (GPS) ; données de cultures : superficie, calendrier, ... ; points d’exhaure : prise en rivière, puisard, ... ; caractéristiques du moyen d’exhaure ; calendrier d’irrigation ; caractéristiques du puisard & coordonnées GPS. Plus de 1.200 exploitants et groupements ont été identifiés dans les 11 différentes zones agricoles. Une base de données a été élaborée à partir de ces enquêtes. Les cartes suivantes ont été établies : occupations agricoles du bassin du Kou ; utilisation des eaux de surface vs. eaux souterraines ; moyens d’exhaure ; efficiences en irrigation ; positionnement par rapport aux berges. Les superficies potentielles irrigables sont déjà atteintes dans certaines régions, mais l’expansion est loin d’être freinée. Le grand enjeu pour le développement de l’irrigation se situe dans la gestion de la ressource en eau. La sensibilisation des agriculteurs sur les bonnes pratiques de l’irrigation permettrait de limiter les pertes lors de l’application de l’eau sur les parcelles et de réduire les inégalités d’accès à la ressource qui existent entre les utilisateurs situés en amont et en aval du cours d’eau.
