THE STATE OF WORLD FISHERIES AND AQUACULTURE 2018 „ „ enabling access to finance; „ „ improving management practices; „ „ creating a resilient sector that is better adapted to climate change and other threats; „ „ improving market linkages (e.g. proximit y to transport and markets). animal diseases, environmental concerns, limited production, social conf licts, restricted access to post-har vesting ser vices, risks for financing, and a lack of resilience to climatic variabilit y, climate change and other threats and disasters (FAO and World Bank, 2015). Aquaculture spatial planning is fundamental for integrated management of land, water and other resources and to enable the sustainable development of aquaculture in a way that accommodates the needs of competing economic sectors and minimizes conf lict. Spatial planning should integrate social, economic, environmental and governance objectives of sustainable development in accordance with the FAO Code of Conduct for Responsible Fisheries (FAO, 1995). The ecosystem approach to aquaculture (see section on this topic in Part 2) and blue growth (see Part 4) are useful frameworks in this context (FAO and World Bank, 2015). Blue growth adds value to the ecosystem approach by linking it to other advances such as improved energ y efficiencies, climate change adaptation and innovations that can improve social, economic and ecosystem outcomes. Continuing advances in remote sensing (e.g. satellites and drones) and mapping technologies, ICT, ecological modelling, improved Internet connectivit y and computer processing enhance support to spatial planning and management processes. FAO provides technical assistance on spatial planning to its Members through studies, technical g uidance, capacit y development and innovative tools (Ag uilar-Manjarrez, Soto and Brummett, 2017). For the future promotion of sustainable aquaculture, it is imperative that integrated spatial planning be effectively applied at both the national and regional levels. In addition, a sound legal and reg ulator y planning and development framework should be in place. Participator y spatial planning, resource allocation and management are essential if aquaculture is to maximize its potential to secure food securit y for a growing population. Spatial planning processes and tools need to be adaptable to a range of local factors, including changing markets, competition, input costs and supply, capital, labour and the urgency of problems or opportunities, as well as the potential impacts of climate change. A growing number of countries are engaging in aquaculture spatial planning. For example, in the Mediterranean, the General Fisheries Commission for the Mediterranean (GFCM) is promoting the concept of allocated zones for aquaculture (A ZAs) (Sanchez-Jerez et al., 2016). Some initiatives in wider marine spatial planning processes integrate the spatial concerns of fisheries and aquaculture with those of other users of the marine space (Meaden et al., 2016), which aim to optimize the sustainable use of marine space for all stakeholders. Feed resources During the period 1995 to 2015, production of farmed aquatic species reliant on feeds increased more than fourfold, from 12 to 51 million tonnes, largely through intensification of production methods for shrimp, tilapias, carps and salmonids (Hasan, 2017a). Today, 48 percent of total global aquaculture production including aquatic plants (66 percent excluding aquatic plants) is produced using exogenous feed. Given the projected increase in aquaculture production, are the trends in feed use sustainable? Aquaculture spatial planning offers many specific opportunities, including: „ „ mapping the presence, absence and distribution of aquatic animal disease to support disease sur veillance, zoning and risk assessment of disease spread (disease risk prevention and management); „ „ ensuring that aquaculture operations stay within the ecosystem’s carr ying capacit y; „ „ reducing conf licts; „ „ improving public perceptions of aquaculture; „ „ promoting the creation of management areas to facilitate certification (Kassam, Subasinghe and Phillips, 2011); While some feeds are farm made and/or comprise fresh ingredients, commercially manufactured feeds are increasingly widely used. Feed may be used to supplement natural production (often | 145 |
