Compound-event analysis in non-stationary hydrological hazards: a case study of the Niger River in Niamey
This study examines compound hydrological hazards in a non-stationary context, specifically focusing on the Niger River in Niamey. The hazard results from the confluence of local Sahelian and more remote Guinean tributaries, displaying seasonal floods. The study first investigates whether Niamey’s annual flood hazard is a compound result of Sahelian and Guinean flows, and then […]
Geospatial Capacity Building for Flood Resilience in the Sahel: the SLAPIS project case study
This study focuses on the development of a people-centred early warning system (EWS) against floods in the Sirba River basin between Niger and Burkina Faso. This densely populated area has witnessed an increase in extreme flooding events in recent years. Several flood forecasting systems in the Sahel exist, although there is no EWS that integrates […]
Comparative Trend Analysis of Precipitation Indices in Several Towns of the Sirba River Catchment (Burkina Faso) from CHIRPS and TAMSAT Rainfall Estimates
The increasingly frequent pluvial flood of West African urban settlements indicates the need to investigate the drivers of local rainfall changes. However, meteorological stations are few, unevenly distributed, and work irregularly. Daily satellite rainfall datasets can be used. Nevertheless, these products often need to be more accurate due to sensor errors and limitations in retrieval […]
Les Services Agrométéorologiques pour les producteurs ruraux pour le développement et la durabilité de l’agriculture au Sénégal, Mauritanie, Mali, Burkina Faso et Niger
L’agriculture sahélienne depuis son origine est confrontée à la variabilité climatique qui a caractérisé son développement au cours des millénaires et a conduit les agriculteurs à adopter des stratégies fonctionnelles pour minimiser les risques. Dans la seconde moitié du XXe siècle, l’agrométéorologie s’est développée comme une science appliquée pour soutenir l’agriculture, réduire les risques climatiques […]
The added value of the process in climate services co-production: Lessons from Niger
Climate services are recognized as an essential tool for sustainable development in strategic and climate-sensitive sectors. In developing countries, particularly in Africa, the literature offers successful examples of application, especially in the agricultural sector, which is dramatically sensitive to climate variability and change. While, initially, particular emphasis was placed on the outcomes of these services […]
Field survey data on the effectiveness of agrometeorological services for smallholder farmers in Niger
The dataset contains the answers of smallholder farmers to a semi-structured field survey and the 2020 yield plot measurements conducted in 8 municipalities of the Dosso and Tillabéri regions in Niger. It is a systematic sampling of about 320 questionnaires and 192 yield plot samples equally distributed in eight municipalities of intervention. The dataset contains […]
Slapis Sahel
SLAPIS SAHELProject Système Locale d’Alerte Précoce pour les Inondations au Sahel Slapis Sahel A Training and Research for Development Project The increase in the frequency and intensity of extreme hydro-meteorological events has prompted Sahelian governments to request support from the international community in implementing early warning systems to help vulnerable riverine communities manage the risk […]
Effectiveness of agrometeorological services for smallholder farmers: The case study in the regions of Dosso and Tillabéri in Niger
The increasing frequency of extreme events in West Africa, such as droughts and floods, has made populations that base their subsistence mostly on rainfed agriculture even more vulnerable to climate threats. Climate Services (CS) are largely acknowledged as effective tools for tackling climate risks in agriculture, particularly in semi-arid developing countries but evidence of their […]
Participatory risk assessment of pluvial floods in four towns of Niger
Intense rainfalls in Sub-Saharan Africa are increasing in frequency. Land degradation, watercourses siltation, and flood defence failure turn these events into disastrous floods. Over the last decade flood risk assessments have been prepared to face these disasters. However, they have frequent limitations in design, accuracy, and completeness. The objectives of this study are (i) to […]
Hydrological Web Services for Operational Flood Risk Monitoring and Forecasting at Local Scale in Niger
Emerging hydrological services provide stakeholders and political authorities with useful and reliable information to support the decision-making process and develop flood risk management strategies. Most of these services adopt the paradigm of open data and standard web services, paving the way to increase distributed hydrometeorological services’ interoperability. Moreover, sharing of data, models, information, and the […]
