Freshwater allocation in an environment of increasing demand and declining quality and availability is a major societal challenge. While biodiversity and the needs of local communities are often in congruence, the over-riding necessity of meeting national demands for power, food and, increasingly, mitigation of the hydrological effects of climate change, often supersedes these.
Fisheries and aquaculture policy for education, research and extension is derivatives of the main national agriculture policy. Fisheries and aquaculture is a dynamic sub-sector of agriculture sector having high growth potential but with low organizational stature in Nepal. The modern aquaculture along with fisheries practices contributes nearly 1% of Gross Domestic Production (GDP) and 2.68% of Agriculture Gross Domestic Production (AGDP).
The Mekong River is one of the great rivers of the world and is characterized by high fish biodiversity. A number of organizations are working at observing and protecting aquatic biodiversity in this hotspot of global importance. Among them are international organizations such as the WWF, Wetlands International, the International Union for Conservation of Nature (IUCN), and the United Nation Environment Program (UNEP) but also regional institutions and national line agencies or nongovernmental organizations (NGOs).
The findings are presented of a survey conducted in Malawi to determine the acceptability by fish farmers of raisingfish in excreta-fed ponds. The use of livestock excreta appeared to be acceptable to the majority of farmers, whereas the use of human excreta was not. Various recommendations are made regarding the promotion of the use of excreta in small-holder farms.
There are increasing requirements for impact assessment by development partners in order to increase the accountability and effectiveness of research and development projects. Impact assessment research has been dominated by conventional economic methods. This context challenges agricultural research organizations to develop and apply alternative impact assessment methods incorporating economic, social, and environmental impact components.
Effects of stocking density on the growth, production, and economics of all-male tilapia (Oreochromis niloticus) were investigated in a rain-fed rice-fish ecosystem for a period of 120 days. Fish were stocked at the rate of 4000, 5000, and 6000 ha-1 in treatments T1, T2, and T3, respectively. Water quality was suitable for fish culture. Significantly higher growth was observed in T1 as compared to other treatments. SGR ranged from 1.26 to 1.51. Survival varied between 79% and 88% with treatment T1 producing the highest survival.
The CGIAR Research Program on Aquatic Agricultural Systems (AAS) is one of the CGIAR’s 15 research programs. Through a program of participatory action research, referred to as “Research in Development”, the Program aims to improve the lives of the many millions of people who depend on aquatic agricultural systems. This Strategy will create the platform to capture, collect, produce, manage, brand and share information that is generated throughout the Program’s lifecycle.
Common-pool resource management is a critical element in the interlocked challenges of food security, nutrition, poverty reduction, and environmental sustainability. This paper examines strategic policy choices and governance challenges facing Cambodia‘s forests and fisheries, the most economically important subsectors of agriculture that rely on common-pool resources. It then outlines policy priorities for institutional development to achieve improvements in implementing these goals.
This handbook is a guide to procedures and practices that should be observed during hub roll-out by the teams coordinating the planning, implementation and reporting of the activities of the CGIAR Research Program on Aquatic Agricultural Systems (AAS-CRP). Given that the program promises to change the way research in development is planned, implemented and reported, it is important that similar practices be observed from the start. This will assist later cross-hub comparisons.
The CGIAR Research Program on Aquatic Agricultural Systems (AAS) has developed its Gender Research in Development Strategy centered on a transformative approach. Translating this strategy into actual research and development practice poses a considerable challenge, as not much (documented) experience exists in the agricultural sector to draw on, and significant innovation is required. A process of transformative change requires reflecting on multiple facets and dimensions simultaneously.
