ahmed idris, al jazeera, otuocha . tom: as we heard, the flooding has been made worse by seasonal rain and planned water release from a dam in neighboring cameroon. lagdo dam is in northern cameroon and was built in 1982. nigeria was supposed to build its own dam to offset the excess, but never finished it. every few years, water is released from the lagdo dam and spills into the benue river. that then floods the revere and its tributaries that flood into nigeria. even with advance warning, the water from the dam affects 13 lead prone states in nigeria, many of which supply the rest of the country with grain and oil. let's bring in our guests now. at the namibian capital windhoek , suleiman adamu, nigeria's minister of water resources. and in abuja, david arinze. a warm welcome to both of you. just a note, we did invite one from the cameroon government to join us on the show but they declined. david, i want to start with you first of all. can you give us a bit of an idea of how bad the flooding is? david: thank you so
