Global population is forecast to reach around 9 billion by 2050. To feed the world, global agricultural output must increase by around 60% from present levels. This must be achieved against a background of increasing competition for natural resources such as water, feed ingredients and farming sites.
Maintaining environmental integrity while massively increasing food production will require farming systems to reduce their unit production environmental footprint. Many farming practices that are regarded as sustainable today will not be acceptable when scaled up. Sustainable intensification of aquaculture means doing more with less. The Sustainable Farming Systems Programme aims to help aquaculture become a more efficient user of natural resources, both in terms of farm productivity and environmental efficiency.
The programme develops better management practices for major aquaculture farming systems, and promotes aquaculture as a secondary or additional use of water resources. The programme focusses on practical interventions that can be directly achieved by small-scale farmers in a developing country context.
Key activities of the programme are:
Development of better management practices for key aquaculture production systems.
Organising small-scale farmers into associations to facilitate cluster-based approaches to extension.
Development of culture-based fisheries as a secondary use of water bodies.
Development of strategic policy frameworks to guide governments and development agencies in promoting sustainable intensification of aquaculture.
The Climate Change and Emerging Global Issues Programme provides policy guidance on key strategic and emerging issues such as climate policy, energy efficiency and alternatives to use of fish meal in aquaculture feeds. The programme endeavours to bring to public domain the positive aspects of aquaculture as a significant contributor to food security and the livelihoods of rural communities, and actively promotes south-south cooperation.
Ths paper enumerates different carp integrated farming systems being prevalent in Asia along with successful case studies indicating potential and constraints of such systems. It recommends to integrate carp farming with agriculture and irrigation, livestock farming, sewage utilisation and water pollution control not only to increase the productivity of land and water and improve the economic conditions of poor farmers but also to maintain health and hygiene of the rural poor and city dwellers alike.
This document briefly describes the status of the aquaculture in the Regional Aquaculture Lead Centre for Thailand circa 1981, in terms of available species and research priorities. Work was conducted on air-breathing catfish Clarias batrachus, snakehead Channa striatus, giant freshwater prawn Macrobrachium rosenbergii, silver barb Puntius gonionotus, snakeskin gourami Trichogaster pectoralis, mussels Perna viridis and oysters Crassostrea spp. Includes brief descriptions of culture methods prevalent for these species at the time.
