PART 1 WORLD REVIEW biological characteristics”. The indicator to measure progress against this target is the “proportion of fish stocks within biologically sustainable levels” (see also “Fisheries and the Sustainable Development Goals: meeting the 2030 Agenda” in Part 2). Based on FAO’s assessment, this proportion was 66.9 percent in 2015. It seems ver y unlikely that the world’s fisheries can rebuild the 33.1 percent of stocks that are overfished in the ver y near future, because rebuilding requires time, usually two to three times the species’ life span. capture fisheries. Almost 95 percent of the world’s inland f isher ies catch is in developing countr ies (Bartley et al., 2015), and 90 percent of inland capture production is consumed in the developing world ( World Bank, 2012). Approximately 43 percent of global inland catch occurs in low-income food deficit countries (LIFDCs) (see Box 11 in Part 2, page 117). This is important, as it illustrates how allocation of resources for monitoring and catch data collection of inland fisheries is often not a priority in countries with more pressing issues to address. One effect of the limited monitoring of inland fisheries is that national catch statistics may be under-reported, as noted i n prev ious ed it ions of The State of World Fisheries and Aquaculture and other in-depth analyses. Pa r t ly a s a consequence of t h i s i nacc u rac y, t he potential for inland fisheries to contribute to nutrition and livelihood resilience in v ulnerable countries may not be fully recognized, particularly in relation to compet ing dema nds for the use of water (see ”Global inland fisheries revisited: their contribution to achievement of the SDGs” in Part 2). However, the continuous increase in the percentage of stocks fished at biologically unsustainable levels does not mean that the world’s marine fisheries have not made any progress towards achieving SDG target 14.4. Yet the world has diverged, with worsening overcapacit y and stock status in developing countries and improved fisheries management and stock status in developed countries (Ye and Gutierrez, 2017). For example, the proportion of stocks fished within biologically sustainable levels increased from 53 percent in 2005 to 74 percent in 2016 in the United States of America (2018), and from 27 percent in 2004 to 69 percent in 2015 in Australia (FRDC, 2016). This divergence is fueled by economic interdependencies through international trade and fisheries access agreements, coupled with limited management and governance capacities in developing countries (see Box 4 in Part 2, page 91). Achieving SDG target 14.4 will require effective partnership between the developed and developing worlds, particularly in policy coordination, financial and human resource mobilization and deployment of advanced technologies (e.g. for monitoring fisheries). Practical experience, as ref lected in the above examples, has proved that overfished stocks can be rebuilt, and rebuilding will produce not only higher yields, but also substantive social, economic and ecological benefits. For some fisheries, increased stock abundance will eventually bring higher catch rates which can benefit fishers through increased profitabilit y. T he catc h f ig u re repor ted at t he nat iona l le vel represents an aggregate of all national production and hence does not provide information on individual fisheries. Increasing or decreasing national catch does not necessarily reflect the state and sustainability of individual fisheries and their stocks, or provide i nsight i nto whether decl i nes i n one f isher y (or subnational area) are offset by gains in another. In the absence of a management f ramework and systematic monitoring, production statistics do not typically provide information on the status of inland fisheries, but rather an estimate of their contribution to food supply. Long-term trend analyses of production are also weak indicators of how well fisheries are m a n ag ed a nd t he s u s t a i n abi l it y of t he f i sh i ng press u re.
