This document presents ex-ante impact evaluations of research for development projects related to aquaculture in Bangladesh, Malawi and Ghana. The Ghana chapter also includes an ex-ante evaluation of a fisheries project. The case studies utilized preliminary versions of guidelines developed specifically for ex-ante evaluations of aquaculture and fisheries projects. The guidelines, found in A Practical Guide for Ex-Ante Impact Evaluations in Fisheries and Aquaculture, are designed to provide an approach for a qualitative examination of the potential for a project to deliver impacts.
The author discusses the development of aquacultural development in Egypt.
Aquaculture has long been promoted by development institutions in Bangladesh on the understanding that it can alleviate poverty. Most of this attention has focused on forms of the activity commonly referred to as ‘small-scale’. This article draws on concepts from the literature on agricultural growth and elaborates a typology of aquaculture based on relations of production which suggests that, in Bangladesh, quasi-capitalist forms of aquaculture may possess greater potential to reduce poverty and enhance food security than the quasi-peasant modes of production generally assumed to do so.
A three-year project was funded by the BMZ/GIZ to examine the benefits of integrating aquaculture and small scale irrigation by identifying improved water allocation and management strategies under current and future climate change scenarios. An integrated modeling approach was adopted to analyze the complex issues involved in the decision processes. A water budgeting approach was used in estimating and balancing the water resources available to farming communities (the supply aspect) and the water demand for agricultural use, including crops and fish farming, within a catchment.
Over the last decade, dramatic increases in the production of a variety of species from commercial aquaculture systems and sharp increases in per capita fish consumption have occurred in Bangladesh. This transition has been made possible by widespread adoption of semi-intensive and intensive production practices, accompanied by growth in the production and use of aquafeeds. Findings relating to the current status of aquaculture in Bangladesh have been reported in greater detail elsewhere.
Details are given of the process of cultivation of mullet (Mugil so-iuy ) used in China, describing the guiding of fry into ponds, harvesting, overwintering, production, disease and predators. Artificial breeding is also discussed, indicating the source and selection of mature fish, hormones and dosages, fertilization and incubation and larval rearing.
Post-tsunami rehabilitation and reconstruction activities in Aceh have been criticised as focusing on vertical reporting at the expense of lateral coordination, leading in some cases to ‘overlaps and redundancies, mistargeting and hastily planned and implemented programs’. Our experience is that effective coordination between implementing agencies, linked to appropriate Indonesian government agencies, can effectively improve the delivery of services, in this case to coastal aquaculture farmers in Aceh.
This paper evaluates the existing evidence of how and to what extent capture fisheries and aquaculture contribute to food security and poverty reduction. In doing so the authors evaluate the quality and scientific rigor of that evidence, identify the key conclusions that emerge from the literature, and assess whether these conclusions are consistent across the sources.
An examination is made of problems involved in the extension of aquaculture in traditional villages in Malawi.Aquaculture is relatively new in the country and requires technical support from very competent personnel who are highly trained in specialized institutions. Extension depends upon effective communication, which is very difficult inthe traditional environments in rural Africa due to the different social structures.
