Monthly flowrate calculation data for the Nwokuy Sub-Basin, Mouhoun Watershed, made for study: "Integrated Water Resources Management in Burkina-Faso through numerical modeling: Case study of the Mouhoun Basin" Population explosion, random changes in weather conditions and human actions are all factors that influence the water resources availability. The objective of the study is to develop a strategy for sustainable water management in the Nwokuy sub-basin by assessing the availability and sustainability of water resources use in this basin through hydrological modelling. Two models were used, namely the GR2M model and the WEAP model. The GR2M (the hydrological model) was applied to fill the gaps in the historical flow data set obtained at the Nwokuy station. With the WEAP model, four scenarios were created and projections were made to the year 2100. Application of the WEAP model scenarios shows that in both deficit years and wet years, water demands for irrigation and domestic use are covered 100% for the first three scenarios. However, anthropogenic action such as the construction of the Samendeni dam could, in the future, lead to cases of unmet demand. The Samendeni flow scenario shows that the water deficit for irrigation could start in 2080 and the water deficit for domestic needs in 2090.

Amount of irrigation water diverted to farms measured at farm inlet. The are data collected based on current practice by farmers in the Bongo Irrigation Scheme and the Vea Irrigation Schemes for the 2014/2015 and 2015/2016 dry seasons.

Researchers in WASCAL, scientists in Ghana and agricultural extension officers in the Upper East Region have been asked for their expert knowledge on different issues related to food and water provision under land use and land cover changes in the Upper East Region. The survey with the scientists in Ghana was conducted between October and November 2015; the survey with WASCAL scientists between December 2015 and May 2016; the survey with agricultural officers between July and August 2016. 37 field officers, 15 scientists in Ghana and 9 scientists in WASCAL have been consulted.
