Substantial floods affected the north of the country in early November and the districts of Mpila and Kangabanzi in the north-east of Brazzaville in late November/early December. The security situation has improved in the Pool region over the past months but remains fragile. Severe malnutrition is affecting the displaced population. Nutrition centres have been recently opened to help malnourished people. The rate of return of displaced people to the cities is rising fast. Of an estimated 810 000 people displaced last year, 370 000 were estimated to have returned by the beginning of January. By February the number of returnees is expected to be more than 400 000, and if the pace continues, some 600 000 could have returned by April or May.
