Problems and issues

  1. poverty Derai is one of the poorest upazilas in the country, with a mean Relative Wealth Index of about -0.279 in the 2nd national decile (rank 50/452). So what: Deep deprivation leaves households with almost no buffer against a lost harvest. Source: Meta Data for Good Relative Wealth Index (HDX)
  2. climate disaster Early pre-monsoon flash floods filling Derai's haors routinely arrive before the boro harvest, repeatedly destroying the upazila's only rice crop. So what: A pre-harvest flood wipes out the year's primary food and income. Source: Department of Disaster Management
  3. water Derai's boro fields depend on aging submersible embankments that are prone to breach when the haors fill early. So what: Embankment failure floods the crop weeks before it can be cut. Source: Bangladesh Water Development Board
