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 (stand-alone)Save and grow: Cassava
A guide to sustainable production intensification
2013This guide is the first on the practical application of FAO's Save and Grow model of agriculture to specific smallholder crops and farming systems. It comes as cassava production intensies worldwide, and growers shift from traditional cultivation practices to monocropping, higher-yielding genotypes, and greater use of agrochemicals. Intensication carries great risks, including soil nutrient depletion and upsurges in pests and diseases.The guide shows how ecosystem-based Save and Grow approaches and practices can help tropical developing countries to avoid the risks of unsustainable intensication, while realizing cassava's potential for producing higher yields, alleviating hunger and rural poverty, and contributing to national economic development. -
ProjectStrengthening Capacity in Managing the Incursion of Cassava Mosaic Virus Infestation in Cambodia - TCP/CMB/3604 2020
Also available in:
No results found.Cassava is the second largest income contribution to Cambodian smallholder farmers after rice. More than three hundred thousand smallholders are involved in planting this crop throughout the country. However, Cassava Mosaic Disease (CMD) poses a serious threat to the cassava industry in Cambodia, as well as in the region, as it can reduce cassava yield by up to 80 percent or more in susceptible varieties. Plant quarantine authorities had limited capacity and facilities to conduct field surveillance and diagnosis and regular pest monitoring, in order to take appropriate actions to restrict disease outbreaks and prevent further spreading to other areas. Farmers also had limited understanding about the disease, and how to respond to and manage the threats it posed. The main focus of the project was to develop human and institutional capacity to tackle CMD, and to control and prevent its spread.
