In the developing world, the majority of people who fish in inland areas do so primarily for subsistence needs. This suggests that survey or census questionnaires which collect information concerning the occupations of respondents will underreport the number of people who fish, and corollary to this, misrepresent dependence on fishing as a support service for food and supplemental income.
The small-scale fisheries sector in many Pacific islands is facing increasing challenges in relation to resource availability, economic opportunity, and demographic and social pressure. In particular, intensifying cash-oriented livelihood strategies can exacerbate existing vulnerabilities and threaten food security and resource conservation.
This report provides a situational analysis of the Egyptian aquaculture value chain conducted in 2013/2014. It deals with the conditions within which the farmed fish value chain operates in Egypt and the general trends that exist in the environment.
Rotational zoning systems (RZSs) have been applied as a spatial management tool for fisheries in developed countries. Fishing grounds are divided into numerous plots and assigned a cyclical periodicity for harvest. This is a distinct spatial management measure that differs from more common measures in the tropics, like periodic closures or marine protected areas. We find that biological prerequisites for rotational closures are tenuous for many tropical reef species, and they are likely to put stocks of threatened species at further risk.
Over recent decades it has become widely accepted that managing fisheries resources means managing human behaviour, and so understanding social and economic dynamics is just as important as understanding species biology and ecology. Until recently, fisheries managers and researchers have struggled to develop effective methods and data for social and economic analysis that can integrate with the predominantly biological approaches to fisheries management. The field is now growing fast, however, and globally, researchers are developing and testing new methods.
Aquaculture has experienced spectacular growth in the past decades, during which continuous innovation has played a significant role, but it faces increasing criticism regarding its ecological and social sustainability practices and the resulting challenges for future innovation processes. However, in the aquaculture literature, there is limited systematic knowledge of how innovation has been approached in terms of how the focus and the scope of aquaculture innovation processes are understood and managed.
Hydropower development with concomitant changes in water and land regimes often results in livelihood transformation of affected people, entailing changes in intra-household decision-making upon which livelihood strategies are based. Economic factors underlying gender dimensions of household decision-making have been studied rigorously since the 1970s. However, empirical data on gender and decision-making within households, needed for evidence-based action, remain scarce. This is more so in hydropower contexts.
This paper aims to devise a farmer participatory method that not only improves farmer management of natural resources, but also monitors the impact of improvements. This assessment is made in terms of: economic efficiency, biological material recycling, species biodiversity and material input-output balance. Results suggest that high performance in all indicators can occur simultaneously and that economic loss from crop failure does not jeopardise performance in biodiversity and recycling.
Pangasius production in Vietnam is widely known as a success story in aquaculture, the fastest growing global food system because of its tremendous expansion by volume, value and the number of international markets to which Pangasius has been exported in recent years.
During the 1930s, people in the Lake Chilwa Basin in Malawi had to cope with both the drying up of Lake Chilwa and the global economic depression. We chose to describe this confluence on Chisi Island as the ‘double crisis,’ and it may at first glance seem obvious, but on examination becomes quite complex. In the case of the Lake Chilwa, the colonial administration introduced cotton production on the dry lake bed to boost the economy of Nyasaland in the face of the economic depression. However, the people of Chisi Island successfully resisted cotton farming.
