Ridge and ditch technique: A strategy for sustainable land management in swampy land areas in southern Bangladesh

Abstract

In Bangladesh, there is a need for socioeconomic sustainability in land management systems. An exploratory study was conducted in the southern part of Bangladesh (Nesarabad) to evaluate the successful strategy of sustainable land management (SLM), where swampy land is transformed, using ridges and ditches. Approximately 25 agro-based sites were studied to evaluate their relevant land use, management, and economic aspects. We determined that nearly 100% of the cultivated lands adopted this technology, representing a combination of SLM measures. The technology was based mainly on structural measures, combined with other conservation measures. The maintenance and recurring activities increased the efficiency of the technology and improved the land quality, making it more useful for various agricultural practices. Most of the lands were cultivated with fruit trees and vegetables, which provided high net average profits with low effort during cultivation. Land users claimed some weaknesses in establishment cost, marketing, transportation, etc. This study assesses these constraints and recommends some suggestions to generate a more suitable scheme for more SLM measures.
