孟加拉国主要河流活跃的泛滥平原上的居民几乎没有得到政府帮助他们应对洪水的支持，他们制定了自己的战略。在这些地区，洪水和侵蚀每年都会影响到许多易受影响的人，因此不可能进行重大的洪水预测工程。对严重洪灾影响的调查发现，他们的全部损失和生命错位是巨大的。这些损失数据被用来评估小规模防洪措施的财务可行性，如房屋加高和防洪避难所，这是这些人的偏好。这些措施的回报率比内地地区的堤防工程更高，前提是该地区在四到八年内不受侵蚀。需要资源、技术援助和当地危险评估的结合，以及政府承诺改善活跃的泛滥平原居民的生活条件。
The inhabitants of the active floodplain of Bangladesh’s main rivers receive little government support to help them cope with floods and have developed their own strategies. Major flood projection works are not possible in these areas where floods and erosion annually affect many vulnerable people. Surveys of the impact of severe floods found that total losses and the dislocation to their lives is substantial. These loss data were used to assess the financial viability of small scale floodproofing measures, such as house raising and flood shelters, which are the preferences of these people. Such measures give better rates of return than embankment projects in mainland areas, provided that the location is not affected by erosion for four to eight years. A combination of resources, technical assistance and local hazard assessment is needed, and a government commitment to improve the living conditions of the inhabitants of the active floodplains.
