Climate information services (CIS) are increasingly in demand to assist farmers in managing risks associated with climate variability and extremes experienced in food production. However, there are significant gaps in the availability and accessibility of these services, especially in aquatic food production in developing countries. In response, this study aims to generate the background knowledge for developing climate information and decision support services tailored for aquaculture farmers in Bangladesh. We surveyed 800 fish-farming households, interviewed 30 key informants, and conducted a systematic literature review to identify climate-sensitive operations and management decisions in aquaculture and to document fish-farmers' awareness of the relationships between climate variability and aquatic food production systems. We also sought to identify the lead time and communication method(s) needed to deploy forecasts effectively and prepare aquaculture farmers to act in response to the forecasts. A fish-farming activity calendar was developed that identified high temperature, cold spell, heavy rainfall, and dry spell events as key climatic phenomena affecting year-round aquaculture operations, including pond preparation and maintenance, fingerling stocking, grow-out management, and harvesting. We also identified five climate-sensitive management decision points and 26 potential advisories in line with specific climate variability to manage induced risks in the day-to-day operations of fish farmers. Finally, the research team developed a decision framework based on the temperature and rainfall thresholds for the grow-out phase of four widely cultivated and economically important fish species in Bangladesh. This innovative decision support approach is to our knowledge the very first endeavor to develop CIS using species-specific temperature and rainfall thresholds to reduce climate risks and ensure resilience capacity for South Asian aquaculture system.

Background: In order to meet the soaring demand for food, there is need for increased food production in Nigeria. Integrated Rice-fish farming is a significant approach to increase food production that will provide social, economic and environmental benefits. Aim: To describe the socio-economic characteristics of integrated rice-fish farmers and to ascertain the availability of rice-fish farming technologies in the study area. Study Design: This was a cross-sectional study. 243 farmers were assessed for their socio-economic characteristics and the availability of rice-fish farming technologies in the study area. Methodology: Primary data were obtained from the field using structured questionnaire. The questionnaire contained questions that address the objectives of the study. Farmers were asked to indicate the rice-fish farming technologies available in the area. Descriptive and inferential statistical tools were used in achieving the objectives of the study in the form of Frequency score, Mean and Percentages. Results: The result indicated that the majority (68.0%) of the farmers were male while 32.0% were female. The mean age of the farmers was 47 years. The result also showed that 79.8% of the farmers were, 9.5% of the farmers were single, while 10.7% were widowed. The result indicated that majority of the farmers 53.5% attained secondary school certificate, 21.8% had primary education. The result revealed that stocking of carp fish (78.60%), use of pests and disease resistant varieties (74.07%), use of organic fertilizer (61.73%), followed by transplanting of rice seedlings (69.96%) and skills in harvesting of rice before fish(53.50%) were the technologies perceived by the farmers as being the most available in the area. Conclusion: The majority (68.0%) of the farmers were male while 32.0% were female and the technology that was most available to the farmers was stocking of carp fish. Recommendations: There is need to encourage more females to engage in farming because female participation will have a positive multiplier effect not only on the family but on the entire community. Federal, State governments and Extension organizations must ensure that farmers are assisted in the use of available technology. The Extension agents should mount more aggressive awareness campaign in the area to enable more farmers embrace the practice of rice- fish farming.

Brackish Water Aquaculture

AbstractAquaculture is the most rapidly growing food production sector globally. In certain coastal social-ecological systems, this has resulted in significant changes and sustainability challenges. In particular, coastal environments which used to support only capture fisheries are becoming sites for brackish water aquaculture production; this impacts the sustainability of aquatic food production. Sustainability challenges associated with aquaculture expansion and intensification necessitate a contextually rooted understanding of institutions and institutional changes which can be used as an informed basis for leveraging institutions to achieve desirable sustainability outcomes in the aquatic food sector. This research used a qualitative empirical case study involving in-depth interviews, participant observation, and analysis of institutional documents in the region of Central Luzon, Philippines. It applied the inter-institutional systems concept which considers multiple institutions with distinct but linked purposes and functions in the societal spheres of state, market, and civil society. The study found that aquaculture emerged as an important livelihood because of rice farmers’ need to adapt to saltwater intrusion into what were formerly rice farms. It grew into an industry due to developments in the availability and accessibility of inputs such as fingerlings and feeds. This process was also driven by the high demand and high profitability of fish farming at the time. Regulatory institutions have not adequately adapted to protect the environment. Market institutions adapted but the changes mostly benefited consignacions (middlemen) and large-scale players. However, organised groups of collaborating smallholder fishers and fish farmers are helping to address the disadvantages they face.

The central role of quality agri-food production in the promotion of a given territory is actually widely recognized by both the economic and marketing literature and the stakeholders involved in the enhancement process of rural systems. On this basis, this work analyzes one of the finest Italian agri-food products: the truffle. This work tries to point out the main problems characterizing the current regulatory framework, the trade and the production of the Italian truffle sector, emphasizing their causes, consequences and possible solutions.
