No Thumbnail AvailableProjectProgramme / project reportInland fish farming alternatives for Ghana: technical and economic aspects 1991
Also available in:
No results found.The purpose of this report is to identify those fish farming alternatives which are best suited to Ghanaian conditions. The perspective is that of the next ten years. In order to identify these alternatives, the authors review: species, culture systems and their economic consequences, water needs and costs, supply of fingerlings and finally specify the physical and economic aspects of the culture systems. The report does not discuss the markets for the fish produced in the fish farm; that is done in Field Technical Report 3 Neither does it discuss the economic availability of inputs; that is done in Field Working Paper 4. However, the analysis of this report rests on the conclusions of those two sections. -

No results found.Ghana has a vast area of inland waters amounting to more than 1 million ha that will continue to be a much more important source of fish than can be supplied by fish farming for the foreseeable future. The estimated potential is about 65,000 t. In order to reach even 20% (13,000 t) of this by fish farming, a total pond surface of 3,250 ha yielding 4000 kg/ha/y would be required. This compares with a present operational pond surface of 209 ha and a yield estimated at about 300 t. Clearly, the man agement and further development of inland fisheries will continue to be an important objective along side the acceleration of the expansion of aquaculture. At present the amount of surface area in which CBF is best justified is relatively small and consists mainly of artificial water bodies in the northern part of the country where stocking and species enhancements can make an important impact on food security, income and employment in an area that is less well off than the rest of the country . Even in the northern part of the country it appears that many of the water bodies which are the potential targets of CBF are self-replenishing and are thus of low priority for stocking. Therefore, encouragement of fishing in water bodies not already fished and promotion of year around fishing in those only fished once per year is a higher priority than stocking.

BookletCorporate general interestEmissions due to agriculture
Global, regional and country trends 2000–2018
2021Also available in:
No results found.The FAOSTAT emissions database is composed of several data domains covering the categories of the IPCC Agriculture, Forestry and Other Land Use (AFOLU) sector of the national GHG inventory. Energy use in agriculture is additionally included as relevant to emissions from agriculture as an economic production sector under the ISIC A statistical classification, though recognizing that, in terms of IPCC, they are instead part of the Energy sector of the national GHG inventory. FAO emissions estimates are available over the period 1961–2018 for agriculture production processes from crop and livestock activities. Land use emissions and removals are generally available only for the period 1990–2019. This analytical brief focuses on overall trends over the period 2000–2018. -
Book (series)FlagshipThe State of Food Security and Nutrition in the World 2021
Transforming food systems for food security, improved nutrition and affordable healthy diets for all
2021In recent years, several major drivers have put the world off track to ending world hunger and malnutrition in all its forms by 2030. The challenges have grown with the COVID-19 pandemic and related containment measures. This report presents the first global assessment of food insecurity and malnutrition for 2020 and offers some indication of what hunger might look like by 2030 in a scenario further complicated by the enduring effects of the COVID-19 pandemic. It also includes new estimates of the cost and affordability of healthy diets, which provide an important link between the food security and nutrition indicators and the analysis of their trends. Altogether, the report highlights the need for a deeper reflection on how to better address the global food security and nutrition situation.To understand how hunger and malnutrition have reached these critical levels, this report draws on the analyses of the past four editions, which have produced a vast, evidence-based body of knowledge of the major drivers behind the recent changes in food security and nutrition. These drivers, which are increasing in frequency and intensity, include conflicts, climate variability and extremes, and economic slowdowns and downturns – all exacerbated by the underlying causes of poverty and very high and persistent levels of inequality. In addition, millions of people around the world suffer from food insecurity and different forms of malnutrition because they cannot afford the cost of healthy diets. From a synthesized understanding of this knowledge, updates and additional analyses are generated to create a holistic view of the combined effects of these drivers, both on each other and on food systems, and how they negatively affect food security and nutrition around the world.In turn, the evidence informs an in-depth look at how to move from silo solutions to integrated food systems solutions. In this regard, the report proposes transformative pathways that specifically address the challenges posed by the major drivers, also highlighting the types of policy and investment portfolios required to transform food systems for food security, improved nutrition, and affordable healthy diets for all. The report observes that, while the pandemic has caused major setbacks, there is much to be learned from the vulnerabilities and inequalities it has laid bare. If taken to heart, these new insights and wisdom can help get the world back on track towards the goal of ending hunger, food insecurity, and malnutrition in all its forms. -
