BookletCorporate general interestLessons from two decades of tilapia genetic improvement in Africa
Genetics in aquaculture: A case study
2023Also available in:
No results found.African aquaculture has increased in importance since 2000 due primarily to dwindling capture fisheries and its demonstrable success in Egypt, which is the only African country among the world’s top ten producers of Nile tilapia (Oreochromis niloticus). This case study provides an overview of tilapia breeding programmes in Africa with a main focus on the Genetically Improved Abbassa Nile Tilapia (GIANT) breeding programme in Egypt. The main steps for establishing a tilapia breeding programme are described, together with the specific lessons learnt in Egypt. -
Brochure, flyer, fact-sheetBrochureGenetically improved farmed tilapia: the GIFT that keeps on giving 2022
Also available in:
No results found.Today, tilapia is the second most cultured fish species in the world. After 28 years of selective breeding, WorldFish’s genetically improved farmed tilapia (GIFT) is now producing its twenty third generation and is being used by 17 governments around the world. The GIFT strain has improved by nearly 10 percent in growth performance per generation. The selective breeding method has also been successfully applied to other tilapia species, Indian major carps and Chinese silver carp. GIFT yields were significantly higher than non-GIFT yields and GIFT species were more profitable and cost-effective than non-GIFT species. WorldFish has commenced selecting GIFT for resilience against pathogens, for improved feed conversion efficiency and better growth under low oxygen conditions, using DNA-based approaches and genomic tools. -
Book (stand-alone)Technical studyThe potential of farming tilapia (Oreochromis niloticus) and freshwater prawn (Macrobrachium rosenbergii) in Vanuatu 2004
Also available in:
No results found.Under the auspices of the Food and Agriculture Organization of the United Nations (FAO) Sub-Regional Office for the Pacific Islands (SAPA) in Samoa, a feasibility study on farming tilapia and prawns was undertaken by SPC Aquaculture Office in November 2003. The objectives were to survey the potential to develop Tilapia (Oreochromis niloticus) and Prawn (Macrobrachium rosenbergii) farming in Vanuatu (further details are given in the Terms of References in Appendix 2).

Book (stand-alone)High-profileStatus of the World's Soil Resources: Main Report 2015
Also available in:
No results found.The SWSR is a reference document on the status of global soil resources that provides regional assessments of soil change. The information is based on peer-reviewed scientific literature, complemented with expert knowledge and project outputs. It provides a description and a ranking of ten major soil threats that endanger ecosystem functions, goods and services globally and in each region separately. Additionally, it describes direct and indirect pressures on soils and ways and means to combat s oil degradation. The report contains a Synthesis report for policy makers that summarizes its findings, conclusions and recommendations.The full report has been divided into sections and individual chapters for ease of downloading:

Book (series)FlagshipThe State of Food Security and Nutrition in the World 2020
Transforming food systems for affordable healthy diets
2020Updates for many countries have made it possible to estimate hunger in the world with greater accuracy this year. In particular, newly accessible data enabled the revision of the entire series of undernourishment estimates for China back to 2000, resulting in a substantial downward shift of the series of the number of undernourished in the world. Nevertheless, the revision confirms the trend reported in past editions: the number of people affected by hunger globally has been slowly on the rise since 2014. The report also shows that the burden of malnutrition in all its forms continues to be a challenge. There has been some progress for child stunting, low birthweight and exclusive breastfeeding, but at a pace that is still too slow. Childhood overweight is not improving and adult obesity is on the rise in all regions.The report complements the usual assessment of food security and nutrition with projections of what the world may look like in 2030, if trends of the last decade continue. Projections show that the world is not on track to achieve Zero Hunger by 2030 and, despite some progress, most indicators are also not on track to meet global nutrition targets. The food security and nutritional status of the most vulnerable population groups is likely to deteriorate further due to the health and socio economic impacts of the COVID-19 pandemic.The report puts a spotlight on diet quality as a critical link between food security and nutrition. Meeting SDG 2 targets will only be possible if people have enough food to eat and if what they are eating is nutritious and affordable. The report also introduces new analysis of the cost and affordability of healthy diets around the world, by region and in different development contexts. It presents valuations of the health and climate-change costs associated with current food consumption patterns, as well as the potential cost savings if food consumption patterns were to shift towards healthy diets that include sustainability considerations. The report then concludes with a discussion of the policies and strategies to transform food systems to ensure affordable healthy diets, as part of the required efforts to end both hunger and all forms of malnutrition. -
Book (stand-alone)Technical bookSoil erosion: the greatest challenge for sustainable soil management 2019
Also available in:
Despite almost a century of research and extension efforts, soil erosion by water, wind and tillage continues to be the greatest threat to soil health and soil ecosystem services in many regions of the world. Our understanding of the physical processes of erosion and the controls on those processes has been firmly established. Nevertheless, some elements remain controversial. It is often these controversial questions that hamper efforts to implement sound erosion control measures in many areas of the world. This book, released in the framework of the Global Symposium on Soil Erosion (15-17 May 2019) reviews the state-of-the-art information related to all topics related to soil erosion.
