“…Further, they indicated that these barriers outweighed irrigation issues, although some are linked. This finding is consistent with Torou et al (2013), who reported that lack of access to seeds and fertilizer are problems affecting the productivity of groundwater irrigation schemes in Niger. The present findings suggest that lack of finance could be a root cause of many of these barriers.…”

Irrigation is a key strategy for food security and poverty alleviation among small farmers in Tanzania. However, the potential of irrigation to improve food security is limited by multiple barriers. This article discusses these barriers within the Kiwere and Magozi schemes. Results indicate that water supply barriers are caused by poor irrigation infrastructure and management. Lack of finance is also a critical barrier to increasing overall productivity. Finance affects farmers' timely access to adequate supply of quality inputs and machinery and availability of transport to access inputs and profitable markets. There is evidence that these barriers have to be addressed holistically.

“…La promotion de la petite irrigation privée à partir des eaux souterraines peu profondes est économiquement envisageable car les coûts des ouvrages de captage et des moyens d'exhaure sont réduits. Depuis 1990, les PIP suscitent un engouement certain dans le pays (Torou et al, 2013). Il s'agit de stimuler cette dynamique à travers des politiques appropriées ; l'adoption en 2015 de la SPIN s'inscrit bien dans cette logique.…”

Résumé -Dans les pays du Sahel, le développement de l'agriculture irriguée est une des solutions pour améliorer la sécurité alimentaire. À travers l'exemple du sud-ouest du Niger, cette étude montre que le développement d'une irrigation à faible coût est possible par pompage de l'eau des nappes phréatiques, ressource renouvelable et mieux répartie dans l'espace que les eaux de surface. Les ressources en eau et en terres irrigables de la zone ont été localisées, quantifiées et leur potentiel à long terme réévalué à partir de données actualisées. Les résultats montrent que 50 000 à 160 000 ha (3 à 9 % de la surface totale cultivée) pourraient être mis en valeur par la petite irrigation à partir des eaux souterraines les plus accessibles (jusqu'à 20 m de profondeur). Cette estimation est du même ordre de grandeur que celle déjà avancée pour les seules eaux de surface, doublant ainsi le potentiel irrigable de la zone.Mots clés : eau souterraine / ressource en sol / irrigation / pauvreté / crise alimentaire Abstract -Small irrigation from shallow groundwater, a sustainable solution to alleviate poverty and food crises in Niger? In Sahelian countries, the development of irrigated agriculture is one of the solutions to avoid repetitive food crises. Considering south-western Niger as a regional case study, this paper demonstrates that increasing low-cost groundwater irrigation represents a long-term solution, using shallow, unconfined perennial groundwater, widely distributed in this region. Groundwater resources and soil characteristics were described and localized in space, quantified in volume and/or surface area, and their longterm potential estimated as a function of updated datasets. Data analysis demonstrates that ∼50,000 to 160,000 ha (3 to 9% of present-day cultivated areas) could be turned into small irrigated fields using accessible shallow groundwater (water table depth 20 m). This would double the regional capacity for irrigation.

“…The transformation of the pastoral zone into a contested landscape will continue unabated, especially due to the agreed usefulness of irrigated gardening in supporting livelihoods facing climate variability in Niger. Yet, under what conditions should such gardens and their respective enclosures be established (see also Torou et al, 2013)? Enclosures redefine the political and social order of a system with new rules and institutions on how the environment is accessed and managed (Schmidt and Pearson, 2016), who benefits, and who is able to decide on boundaries.…”

a b s t r a c tDivergent adaptation to climate variability produces unequal adaptive capacities between user groups and contributes to a contested landscape. This article examines divergent adaptations in the context of land tenure shifts in the pastoral zone of Niger. The management of the pastoral commons is shifting from a commonly-shared to private regime as former pastoralists take up new livelihoods, such as irrigated gardening. A method combining political ecology and remote sensing is used to study social ecological system (SES) dynamics in order to demonstrate the relationship between divergent adaptation, water-based conflict, land tenure shifts and land use/land cover change. Examining pastoral and agro-pastoral users' historical perceptions of land use and tenure change, results indicate that disputes over the access to and use of commonly shared natural resources are linked to increasing enclosures of ephemeral and permanent lakes in the pastoral zone of Niger. Remote sensing-derived information is used to identify and quantify the area and volume of enclosures around commonly shared water sources in the northern pastoral zone of Niger from 2003 to 2013. The study identifies the government-supported development of irrigated gardens in the pastoral zone as a divergent adaptation with its related conflict dynamics between user groups and highlights the land tenure shifts from a commonly to a privately managed regime. The findings have broader implications for the wider Sahel and provide recommendations as to how adaptation programs could be better designed and implemented in the pastoral system.
