FAO Fisheries and Aquaculture Circulars While many countries in the Asia-Pacific region have made commendable efforts to set up policies, as well as administrative, legal and regulatory frameworks to properly develop and manage aquaculture, some countries are still lagging behind. And in some of the countries that have made conducive policies, implementation is delayed by a lack of financial and skilled human resources. This issue must be addressed as a priority if the Asia-Pacific aquaculture sector is to continue to develop sustainably.

The Asia-Pacific region is remarkably diverse and wide ranging, geographically, in its flora and fauna, culturally, institutionally and economically. The region includes the two most populous countries in the world, China and India, a greater part of the Asian continent, the Australian continent, and many small islands, mostly in the Pacific Ocean, which are some of the smallest island nations in the world. Fisheries and aquaculture are socio-economically important sectors to most nations in the Asia-Pacific region and most nations in the region have high rates of fish consumption, mostly sourced from aquaculture although the small island nations depend to a greater extent on capture fisheries. This review entails analyses of the aquaculture sector in Asia-Pacific including the status and trends, progress made in achieving sustainable development, salient challenges, issues and anticipated future development. Status and trends are based on data extracted from the FAO Fishery and Aquaculture Statistics (FAO, 2020a; FAO, 2020b), unless stated otherwise, and are mostly for the period from 2008 to 2018 and occasionally for the period from 1990 to 2018 for relevant historical comparison and longer-term contextual analyses.

The Near East and North Africa (NENA) region covers 18 countries and territories: Algeria, Bahrain, Egypt, Iraq, Jordan, Kuwait, Lebanon, Libya, Morocco, Oman, Palestine, Qatar, Saudi Arabia, Syrian Arab Republic, Tunisia, United Arab Emirates, Western Sahara and Yemen with a total land area of 9.8 million km2. The region is mostly arid or semi-arid but has extensive coastlines and includes a wide range of different economies from high income, hydrocarbon-rich countries to low-income states, some of which have been severely impacted by conflict in recent years. NENA aquaculture production was worth USD 2.3 billion in 2018, two-thirds of which came from Egypt and around one-quarter from Saudi Arabia. Production has grown rapidly since the 1980s, more than doubling over ten years and increasing by 50 percent over the five years preceding 2018 to reach 1.7 million tonnes. Egyptian fish farms accounted for 92 percent of production and Saudi Arabia for 4.2 percent while other significant producers included Iraq (25 737 tonnes), Tunisia (21 826 tonnes), Algeria (5 100 tonnes), the United Arab Emirates (3 350 tonnes) and the Syrian Arab Republic (2 350 tonnes). Although current aquaculture production levels are low, all these countries have high ambitions with further developing the sector, often for improved food self-sufficiency.

The present regional review and synthesis for sub-Saharan Africa (SSA) provides an overview of major issues and trends in the aquaculture sector between 2004 and 2014 with emphasis on outstanding issues over the last five years. The regional review reflects development in 41 countries in SSA for which production was reported to FAO in 2014. The production volume and value data have been derived from the latest FAO global aquaculture dataset 1950-2014 (FishStat).

This book focuses on the transformation of Bangladesh in respect to its people, geography, economy and environment. The authors discuss current problems such as vulnerability caused by environmental degradation in Bangladesh but also opportunities of this rapidly changing country. The book explains how the country is rapidly transforming from a rural subsistence agrarian based economic system to a new economic partner contributing to global processes. Bangladesh is presented as an example for the changes in the Global South, where a mismatch is often observed in linking resources and activities with environmental sustainability, possibly due to insufficient base-line knowledge. As faster growth is marginalizing resources to increase the GDP, the sustainability of resource exploitation is being questioned. The authors describe the vulnerable situation caused by possible sea-level rise, soil degradation, biodiversity loss, climate extremities, urbanization, and population displacement. This volume offers comprehensive knowledge about the geography and environment of Bangladesh and aims to help readers further investigate the issues and work on solutions. The book appeals to academics, professionals and students at all levels interested in Bangladesh as well as environmental problems and geographical issues in a rapidly transforming country.

FAO Fisheries and Aquaculture Circulars All Near East and North Africa countries have sea borders, whereas fresh water resources are scarce. Yet, aquaculture production in the region has doubled over the past decade, with an average annual growth rate of 9.7 percent, and the role of aquaculture in total fish production is steadily increasing. It should be noted that the Arab Republic of Egypt and the Islamic Republic of Iran contributed 74 and 21 percent respectively to total aquaculture output.

Due to the increasing pressure of a globalized economy and under the effects of a changing climate, biological invasions have become a frequent feature of marine and freshwater environments. Global fisheries and aquaculture are therefore required to adjust to these changes, with the dual aim of reducing the negative ecological consequences caused by these species and making the most of the advantages they might bring. Here, capitalizing on a wide spectrum of management actions which can be implemented to control and/or adapt to aquatic invasions, nine measures are presented; they can be grouped under environmental, social or socioeconomic strategies, exploring their potential, main challenges and enabling factors. The nine measures, provided with key recommendations, are: #1: Develop and manage a commercial fishery #2: Promote recreational harvesting #3: Explore market opportunities #4: Implement outreach programmes #5: Foster stakeholder engagement #6: Implement spatial control #7: Implement biological control #8: Restore ecosystems #9: Do nothing These suggestions, discussed among a group of international experts and presented in a synthetic form, may be used as a practical resource (though not an exhaustive one), to aid in the evaluation and identification of appropriate fisheries management responses to aquatic invasive species in the context of climate change. While it may not address all the complexities of the subject, it provides a starting point for adaptation strategies, recognizing the diverse legal, cultural and socioeconomic conditions in different fishery contexts, offering valuable insights for policymakers, fisheries managers, and practitioners who have to deal with aquatic invasions.
