Brochure, flyer, fact-sheetProtecting cassava, a neglected crop, from pests and diseases 2019
Also available in:
No results found.Cassava (Manihot esculenta Crantz) is the fifth most produced staple food crop in the world, being a basic source of staple food for an estimated 800 million people worldwide. Cassava is an increasingly popular crop. Cassava is grown by smallholder farmers in more than 100 tropical and subtropical countries of Africa, Asia and Latin America. Thanks to its efficient use of water and soil nutrients and tolerance to drought, cassava can produce reasonable yields using limited or no inputs, even in areas with poor soils and unpredictable rainfall. Like other crops, cassava is vulnerable to pests and diseases that can cause heavy yield losses. Insect pests such as white flies and mealybugs, and diseases caused by viruses and phytoplasma, affect the production of cassava worldwide. Of the viral diseases, Cassava mosaic disease (CMD) and Cassava brown streak disease (CBSD) are the most widespread, severely affecting at least 50 percent of cassava crops in Africa. CMD and CBSD pose a serious threat to the food security of 135 million people in Central and East Africa alone. At least half of all plantings in Africa are affected by one of these diseases. Scientists estimate that annually, 15–24 percent (equivalent to approximately 12–23 million tonnes) of the crop is lost due only to CMD in Africa. -
Book (series)Qualitative risk assessment for African swine fever virus introduction
Caribbean, South, Central and North Americas
2022Also available in:
No results found.Following the re-introduction of the African swine fever virus (ASFV) in the Americas after 40 years of absence, FAO conducted a qualitative risk assessment for the likelihood of entry of ASF from the Dominican Republic and Haiti to unaffected countries and territories of the Americas and the likelihood of exposure to susceptible animal populations should the disease be introduced. In addition, the potential economic and social impact of ASFV spreading across the continent was assessed. The risk assessment covers the period of December 2021 to February 2022 and considered six risk pathways of introduction and spread. The methodology, information used and results of the risk assessment and economic impact assessment are available in this publication along with recommendations for prevention and control of ASFV introduction and spread in the region. In addition, the publication compiles information collected from 35 countries/territories in the Americas through a questionnaire and presents evidence on the complex swine/pork value chains in the region retrieved from various sources. -
ProjectSupporting the National Technical Capacity Building for Developing Shrimp Farming Sector in Cambodia - TCP/CMB/3607 2020
Also available in:
No results found.Cambodia experienced a decade of rapid economic growth until 2014, putting it among the world‘s fastest-growing economies during this period. It has also been one of the world’s best performing Millennium Development Goal achievers. The country has a rich biodiversity of freshwater and marine resources, with the primary source of fishery production being the wild capture fisheries in the Great Lake, the Mekong, the Tonle Sap and Bassac rivers and their associated floodplains. Cambodia’s coastal zone, located on the south-west edge of the country, extends for 435 km, and includes 85 100 ha of mangrove forests in three provinces: Koh Kong, Preah Sihanouk Ville and Kampot. However, the production from both inland and marine fisheries has rapidly decreased as a result of overfishing, lost fish habitats, the construction of dams for hydropower, the increased use of chemical agriculture activities and the effects of climate change. Aquaculture thus plays an important role in meeting the present and future protein consumption demands of an ever-increasing population, as recognized in Cambodia’s Rectangular Strategy III, the National Strategic Development Plan 2014-2018, the Agricultural Sector Strategic Development Plan 2014-2018 and the National Strategic Plan for Aquaculture Development in Cambodia 2014-2030. There is great potential in Cambodia for the continued development of marine aquaculture, above all for shrimp, finfish and crustacean farming in the coastal zone. In order to support the development of shrimp farming, the Ministry of Agriculture, Forestry and Fisheries requested FAO support to develop the capacities of the newly established Marine Aquaculture Research and Development Centre. The aim of the project was to equip MARDeC technical staff with up-to-date knowledge and practical skills in shrimp farming using innovative biofloc technology, as well as in other good management practices.
