Book Description
The FAO Fishery and Aquaculture Circular C942 Revision 3 (C942 Rev. 3) updates and expands the scope of previous revisions of the circular. C942 Rev. 3 is an important baseline document, intended to assist in the global understanding of inland fisheries and inform dialogue on their current and future role. The third revision reviews the status and trends of inland fisheries catch at global, continental and subcontinental levels. It places inland capture fisheries in the context of overall global fish production, and calls attention to the importance of inland capture fisheries with respect to food security and nutrition and the Sustainable Development Goals. It quantifies global inland fisheries resources in terms of food production, nutrition, employment, economic contribution with respect to those countries/regions or subnational areas where they are important. A characterization approach to distinguish large-scale and small-scale fishing operations and their relative contributions is provided. The review provides estimated economic values of inland fisheries, as well as a valuation of potential replacement cost of these (in terms of dollars, other resources such as land and water, feeds). There is also an analysis of the extent and economic value of recreational inland fisheries. The contribution to employment and the gender differences related to this are quantified. The linkages between inland fisheries and biodiversity are also explored. C942 Rev. 3 discusses ways to measure and assess inland fisheries, in particular, how to establish more accurately inland fishery catches in the many situations where there are challenges to collection of catch statistics.

Book Description
The fishery statistics reported to FAO by countries and maintained in the FishStat database are analysed for trends in quantity and composition of catches from 1950 to 2009. Catches have been increasing at a steady rate throughout the period. Fish from inland water capture fisheries are an important source of animal protein, especially in landlocked countries and for populations riparian to lakes and rivers. Finfish contribute about 90 percent of the catch together with some crustaceans and molluscs. The accuracy of reporting of catches by taxonomic group has improved with time and more groups are being reported in 2009 than in 1950. At the same time, the percentage of catches assigned to the generic "freshwater fishes NEI" category has declined. Trends in catches and taxonomic groups are analysed for subcontinental regions under a more general continental heading. The regions are divided mainly by geography, although in some cases economic and political considerations are used. Catches in the various regions of Africa, Asia and South and Central America have risen steadily over the period of the review, although there are local exceptions to the general trend. There is clear evidence that such increases are real in some individual fisheries, but generally the increases are attributed to improvements in reporting, whereby catches that were already there but previously ignored are now being incorporated into the reports. Catches in North America, and most of Europe, have declined in the same period, which is attributed to shifts in economic conditions that make fishing not longer financially viable, and a greater public demand for recreational fishing. Catches from eastern Europe and the Russian Federation declined from a maximum in the 1980s, but have shown some signs of recovery in the last decade. In general, the world's inland fisheries still appear viable although environmental pressures, such as damming, water abstraction and overexploitation, pose a potential threat to the maintenance of present levels of reproduction and recruitment, and hence, ultimately catch.

Book Description
This illustrated report sets out a global review of the state of the world's freshwater resources, based on the collective work of 24 United Nations agencies, following on from the conclusions of the first UN World Water Development Report 'Water for People, Water for Life' published in 2003 (ISBN 9231038818). This second edition discusses progress towards the water-related targets of the UN Millennium Development Goals and examines a range of key issues including population growth and increasing urbanisation, changing ecosystems, food production, health, industry and energy, as well as risk management, valuing and paying for water and increasing knowledge and capacity. It contains 16 case studies which consider key challenges in water resource management and makes a number of recommendations to guide future action and encourage sustainable use, productivity and management of our increasingly scarce freshwater resources.

Book Description
This Scientific Bibliography of the “Far Northern Drakensberg” is a continuation by the Afromontane Research Unit of the University of the Free State (ARU) to document published and other similar works on the mountains of the summer rainfall area of South Africa. It follows “A Scientific Bibliography of the Drakensberg, Maloti and Adjacent Lowlands” which was published in 2020 (Moffett 2020), and which covered the area between the North-Eastern Cape and the North-Eastern Free State. The current work extends this northward by including articles and publications dating back to 1875 (E.Cohen, on the Lydenburg goldfields) reaching as far as the Wolkberg and Woodbush near Tzaneen in Limpopo Province. Figure 1 shows the boundary of the area covered, and although referred to as the Far Northern Drakensberg in this work, it is identical to that described as the LMEE, Limpopo, Mpumalanga & Eswatini Escarpment by Clarke et al (2022). Although slightly separate from the “lower” escarpment, the mountainous Barberton and adjacent Eswatini area, as well as the Leolo Mountains in eastern Sekhukhuneland are also included. Details on how the boundary in figure 1 was determined are given in Clark et al (2022). Bibliographies on two further ranges in the summer rainfall area, viz. the Magaliesberg in Gauteng province and the Soutpansberg in Limpopo province are to be the subject of future compilations.

Book Description
This document has been adapted from the research protocol used to compile country case study data and to produce the results summarized in the 2023 report titled Illuminating Hidden Harvests: The contributions of small-scale fisheries to sustainable development (hereafter, IHH study) (FAO, Duke University & WorldFish, 2023). It has also been designed in conjunction with the e-learning course titled Collecting secondary data on small-scale fisheries, and aims to support practitioners and researchers around the world in compiling national and subnational data and assess the contributions and impacts of small-scale fisheries of interest to sustainable development. These contributions of small-scale fisheries are categorized according to the environmental, economic and social (including gender equality and nutrition and food security) dimensions of sustainable development, as well as the governance of small-scale fisheries. The approach to compile IHH data was developed in a way that: (i) is adaptable to each country’s context and data availability; and (ii) is comprehensive yet straightforward and cost-effective. While originally designed to be conducted at the national level, this approach can and should be modified as desired to fit different scales of study, and to respond to the particular needs and priorities of individual researchers’ regions of interest. As the name implies, the approach was designed to compile existing data on small-scale fisheries, and not to collect it. Rather, this approach only reinforces the importance of collecting more detailed data specific to small-scale fisheries (for example, as distinct from large-scale fisheries, aquaculture and recreational fisheries), in order to help fill the knowledge gap on small-scale fisheries’ contributions to sustainable development. Given the vast diversity of small-scale fisheries in different countries, a standard definition of “small-scale fisheries” is not prescribed here, nor in the IHH study; researchers should refer to the definitions used in each country context. However, to better characterize fisheries and the differences among them that often contribute to local definitions of small or large-scale fisheries, the IHH study and this approach used a fisheries activity characterization matrix. This tool provides a characterization of the small-scale fisheries subsector at the country level and allows researchers to assess the “scale” of small-scale fishing activities in a more relational manner, thus avoiding the imposition of fixed definitions.
