DEMOCRATIC REPUBLIC OF CONGO IMPACT OF CROSS-SECTORAL APPROACH TO ADDRESSING KONZO IN DRC Households in Province, DRC rely primarily on agriculture for food; cultivating cassava as the main crop and have limited dietary diversity. Due to the presence of cyanide in cassava, a poisonous chemical in unprocessed cassava, the retting process to leach out cyanide prior to consumption is essential. Improperly processed cassava causes konzo, a neurological ailment triggered by sustained dietary exposure to cyanide. Since local knowledge of the food-related origins of the disease is limited, local beliefs and traditional customs were found to be the main drivers of the high incidence of the disease. DRC

Background What is Konzo? From December 2009 to October Konzo is a sudden epidemic spastic 2011, Action Against Hunger paraparesis (paralytic) disease which (ACF-USA) implemented an leads to a permanent paralysis of intervention in the the affected person’s lower limbs. It is of the Democratic Republic of Congo a neurological ailment triggered by (DRC), addressing factors underlying sustained dietary exposure to cyanide the konzo epidemic affecting the present in improperly processed population of district. cassava. Overall, vulnerability to konzo is heightened by the The “Integrated Programme for the combination of low protein intake Eradication of Konzo in the Territory (associated with low dietary diversity), of Kwango in DRC” project was poor soil conditions (which favor the financed by the European Union (EU) cultivation and consumption of bitter Food Facility and aimed to eradicate cassava varieties high in cyanide), the disease through a cross-sectoral and lack of sufficient water resources approach focused on nutrition for thorough processing. education and training, dietary diversification, improved water access and agricultural processing. Figure 1: ACF program area in , Bandundu province, DRC The strategy also aimed to address the high rates of malnutrition seen in konzo cases [25.8% global acute malnutrition (GAM) prevalence in konzo affected children less than 18 years old, 69.3% of GAM in konzo affected adults]. A total of 22,000 households benefited from these activities. Due to limited resources, project activities were not carried out in all konzo locations, but rather in the most affected villages.

The project was implemented in 396 Diverse environmental factors, villages in the highly affected areas such as soil fertility and soil water of Kahemba, Kajiji, Feshi and Panzi retention, affect the quantity and and to a lesser extent in Kenge, Boko, quality of harvests. Popokabaka, Kasongo Lunda, Wamba Luadi and Kitenda across the Territory Water access is a critical factor in of Kwango. Prior to implementing the konzo incidence, with access limited project, ACF conducted a baseline by both distance to and seasonality study1 in collaboration with the of water points. Water coverage Ministry of Health (MoH)’s PRONANUT levels are very low (4 to 5% or Programme National de Nutrition coverage)2, leading rural farmers in DRC where 2,388 suspected konzo to directly soak the cassava on river cases were screened and 2,218 were banks, in ponds or in swampy areas confirmed. to avoid carrying water back to their homes.

7 This document is part of a set of case studies on ACF Food Security and Livelihoods interventions which aim to reduce and/or prevent undernutrition. It has been developed by the ACF “Aligning Food Security and Livelihoods with Nutrition” Working Group. The aim of the “Aligning Food Security and Livelihoods with Nutrition” Working Group is to promote and scale up nutrition-sensitive Food Security and Livelihoods interventions, within ACF as well as partner organizations. The Working Group promotes these interventions by gathering lessons, building evidence, developing tools and guidance and building capacity.
