In 2005, roughly 45% of the total populations of Bangladesh living below the poverty line and of them 53% are rural poor people. Therefore, a significant gain in rural poverty reduction will be crucial for Bangladesh to reach the national poverty reduction target. As 63% of the total employed people engage in some kind of agricultural activities, without pro-poor agricultural growth it is impossible for a country like Bangladesh to reduce poverty. This article attempts to analyse the impact of agricultural growth on rural poverty reduction by using time series analysis in Bangladesh during 1973 to 2003. The study shows that rural poverty reduction is possible by increased agricultural production, for which again efficient spending of government budget and skilled human capital are crucial factors. Also findings suggest that, increased the share of non-farm activities will help to poverty alleviation in rural Bangladesh.
