摘要

西北地区是孟加拉国种植面积最大的地区,对孟加拉国最近实现稻米粮食安全至关重要。仅西北地区就供应了全国约35%的灌溉水稻和60%以上的小麦和玉米。西北地区也是地下水水位下降最令人关切的地区,特别是在巴林德地区,这导致一些地区缺乏饮用水和灌溉用水。然而,目前尚不清楚地下水位的下降是由于观测到的降雨量减少,还是由于过度使用,还是由于这些因素和可能的其他因素的某种组合。为了应对这一挑战,澳大利亚政府通过其外交和贸易部可持续发展投资组合,正在资助一个涉及CSIRO和几个孟加拉国合作伙伴的项目。

Sustaining groundwater irrigation for food security in the northwest region of Bangladesh
The northwest region has the largest areas of cropping in Bangladesh and is crucial to Bangladesh’s recent attainment of rice grain food security. The northwest region alone supplies about 35% of the irrigated Boro rice and more than 60% of the wheat and maize of the whole country. The northwest region is also the region of greatest concern over falling groundwater levels, particularly in the Barind area, which have resulted in a lack of access to water for drinking and irrigation in some areas. However, it is not clear whether the declining groundwater levels result from an observed decline in rainfall, or from excessive use, or from some combination of these and possibly other factors. To address this challenge, the Australian Government, through its Department of Foreign Affairs and Trade (DFAT) Sustainable Development Investment Portfolio, is funding a project involving CSIRO and several Bangladeshi partners.
