Synopsis (short abstract) vast tract of low lying tidal flood plain in the coastal area of Bangladesh is flooded twice in a day. For many years, these lands used to be protected by dwarf embankment under the initiative of local Zamindars. Paddy cultivation in rotation with fish production were the main activities of the people of the area. Dykes constructed by the Zamindars were of inadequate section, low quality and required continuous maintenance. Dykes often collapsed due to hydrostatic pressure and errossive action of wind and current. Drainage facilities provided were also inadequate. After abolition of Zamindari system in Bangladesh, the Government started construction of Coastal Embankment Project in 1961 under USAID assistance. An area of about 5000 sq. miles were given protection in the districts of Khulna, Barisal, Noakhali and Chittagong. The Coastal Embankment Project was intended to increase agricultural production by preventing saline water inundation, reducing the flood hazards and preservi ng sweet water in the internal channel system. Effect of river confinement and future land use pattern were not taken into consideration and century long practice of paddy-cum-fish culture were stopped. An important consequence of the river confine ment was the rapid river siltation. This problem was very much pronounced in the western zone of the delta and many of the drainage sluices could not effectively function during the monsoon result inundation within the polders. Coastal Embankment Pr oject, however, has provided a favourable infrastructure

    Integrated agriculture-aquaculture: a primer 2001
    Also available in:
    This primer is an edited and slightly revised version of a previously published integrated agriculture-aquaculture (IAA) technology information kit. It contains 38 contributions in seven sections covering sociocultural, economic and environmental considerations in introducing IAA technologies, overviews and various examples of integrated farming systems including livestock-fish and rice-fish integration, as well as selected aspects of fish feeding and management, and fish breeding and nursing in IAA. The document aims to give decisionmakers concerned with agriculture and rural development an overview and a basis for understanding the principles of IAA, and to help them decide whether to embark on IAA activities and include these in their program portfolio. For those who work directly with farmers, this primer aims at providing good examples of IAA, but it is not intended to be a compilation of procedures that should be strictly followed. Rather, this primer should help convince i ts readers/users that farmers can improve their livelihoods by either introducing IAA, or by further developing the many IAA opportunities on their existing farms.
