Historical cases and food security risks by country

Cameroon

Historical cases

Cameroon, whose capital is Yaoundé, lying at the junction of western and central Africa, has an ethnically diverse population that is among the most urban in western Africa [1]. The urban population of Cameroon is growing quickly, and secondary cities are where the majority of this expansion is occurring. Even with high rates of engagement in food production, livestock raising, and a robust informal food marketing system, one of the household food security surveys conducted in 2017 indicated that two-thirds of households experienced severe food insecurity, and from the several historical case studies within the country. Below are some of the major pointed out cases [2].

Historical case studies

CS 1.1: Bird Flu
Year of outbreak2016
Affected regionCenter / South / West
Category affectedPoultry
DescriptionThe virus had gone from the main farm in the Center region to the main poultry market in Yaoundé and even in the sub-region. Then, this virus ended up in the Western region. Then it exploded and spread to almost all markets in the Central, South, and West basin.
Severity for the affected categoryHigh
Effect on the ecosystemSupply of eggs and chicken meat was interrupted.
Severity for humansSocial effect: loss of investment, loss of jobs, supply of eggs and chicken meat interrupted.
Effects on economyLoss estimated at around 20 billion F.CFA. More than 160,000 jobs lost, the production of table eggs has fallen from 5 million to around 2 million eggs per day. In the “broiler” component, the production outlook for 520 million chickens has been revised downwards to 26 million at the end of 2017.
Possible mitigation actions / CountermeasuresImplementation of emergency stamping-out operations in the identified foci, their destruction by incineration and burial under the supervision of the heads of the veterinary services. Installation of sanitary barriers at the level of poultry farms, with prohibition of access to any unauthorized person, during the period of the conduct of stamping-out operations and disinfection of outbreaks by special teams.
Possible prevention measuresEstablishment of a surveillance and early warning system in Cameroon and in all the CEMAC States.

Risks

In Cameroon, food insecurity essentially results from inadequate food consumption (10.7% of the population), negative coping strategies based on food consumption or on livelihoods (respectively 10.2% and 17.2% of households), or economic vulnerability, with 33.2% of the population spending 65% or more on food. In addition, 1.1% of households suffer from severe to very severe hunger. Overall, the food insecurity situation has deteriorated from 12.8% in 2019 to 20.4% in 2020. The North West (40.0%), South West (30.7%), Littoral (25.1%), the Far North (24.8%), Adamaoua (22.1%) and the West (20.5%), which are suffering the effects of various humanitarian crises, are the most affected by the food insecurity. In order to ensure the food security of the most vulnerable populations, the following recommendations are made after a National Food and Nutrition Security Survey (ENSAN) in September 2020 [32]:

  • Provide emergency humanitarian assistance to food insecure populations severe, especially in the North West, South West, East and Far North regions.
  • Ensure the nutritional education of populations living in regions where the diet is not very diversified and presenting micronutrient deficiencies.
  • Implement resilience programs to strengthen the livelihoods of vulnerable households over the long term.
  • Set up stocks of food products and agricultural seeds throughout the national territory.
  • Pay special attention in terms of assistance to female-headed households who tend to be more vulnerable.

Historical cases

Uganda, at times referred to as the pearl of Africa, whose capital city Kampala is bordered to the east by Kenya, to the north by South Sudan, to the west by the Democratic Republic of the Congo, to the south-west by Rwanda, and to the south by Tanzania [3]. Despite being estimated that about 70% of Uganda’s working population is employed in agriculture [4], both big and smallholder farmers across the country face a wide range of agricultural production risks, with climate change and variability presenting new risks and vulnerabilities. Below are some of the historical case studies from the country.

Risks

Food and nutrition security remain Uganda’s most fundamental challenge for human welfare and economic growth. The sorry state of food and nutrition security in Uganda spells the need for strategic interventions to enable the government at various levels to meet its obligations towards the many hungry and under-nourished Ugandans [33]. Food and nutrition insecurity is an important component of the development challenge the nation faces and fundamentally undermines efforts to meet its development vision.

In Uganda, the problem is not so much on access to food but, rather, malnutrition. In comprehensively addressing these problems, Uganda Food and Nutrition Strategy (UFNS) was formulated as a guide to action for the Uganda Food and Nutrition Policy (UFNP) that was approved by the government in 2003. The vision of the UFNS is a hunger-free country without malnutrition [34].

Ethiopia

Historical cases

Ethiopia is located in the Horn of Africa and has a diverse topography with an altitude ranging from 125 m below sea level in the Danakil Depression to 4,620 m above sea level in the Ras Dashen [5]. The climate varies from a temperate type in the highlands to hot arid in the lowlands. The country is the second most populous in Africa with nearly 120 million inhabitants. Ethiopia’s economy is dependent on agriculture, which accounts for 33 percent of the total GDP, 80 percent of exports, and supports an estimated 75 percent of the country’s workforce [6]. The livelihood of the rural community depends mainly on crop production and livestock rearing. Hence, given the inherent link of these livelihood activities to natural resources, they are largely at the mercy of uncertainties driven by climate change, including extreme events such as drought and flooding in lowland areas of the country. Frequent occurrence of drought and flooding in the country created conducive environmental conditions for various disease outbreaks, tsetse fly, desert locust and invasive aquatic weed infestation, with a consequent significant negative impact on crop, livestock and fish production. The net effects of these climate crises affected the livelihood of people and led millions to the greatest hunger crisis, mass displacement, livestock death and degradation of natural resources including surface water and soil. Scanning the spatial and temporal analysis of climate extremes, which are directly or indirectly responsible for the occurrence of other disasters, is very crucial to strategically design long-lasting interventions and prevention measures for the country and other African countries in general. Hence, the tables below present the major historical cases which resulted in food insecurity in Ethiopia and affected production of export commodities to EU-Africa countries that require sustainable mitigation and prevention measures.

Year of outbreakSince 2002
Affected regionLakes Tana, Ziway, Hawasa, Abaya, Koka
Category affectedFish and livestock
DescriptionThe lakes of Ethiopia are recognized for their outstanding biological diversity, fish production and societal significance. However, the lakes are facing substantial threats due to anthropogenic factors such as intensified pollution from point and non-point sources and increased water abstraction for growing irrigation. Currently, a decline of 20% in fish production has been reported from the major fish-producing lakes. Moreover, the nutrient-rich effluents entering the lakes through runoff create conducive conditions for eutrophication and toxic algae development, affecting fish production and the health of livestock and humans dependent on the lake water.

Possible prevention measuresSatellite-based monitoring of infestation, apply control mechanisms, restock fish fingerlings from hatcheries, control nutrient runoff from the catchment, control by utilisation.

Risks

Ethiopia is committed to the Sustainable Development Goals and has wholeheartedly participated in the UN Food Systems Summit (UNFSS). The Ethiopian food systems transformation (EFS) course charted by bringing together the public institutions, multilateral and bilateral organizations, the private sector, civil society organizations, and universities and research institutes. The high-level First EFS National Dialogue evaluated the current state of Ethiopian Food Systems and identified the key challenges that need to be addressed; and then identified and prioritized key 22 ‘game changing solutions’ to address the challenges identified in the First Dialogue. The Third National Dialogue then brought together key stakeholders to launch the EFS vision and affirm Ethiopia’s commitment to create a strong and equitable food system [35].

Ethiopia has made great strides in ensuring food security for all citizens. However, extensive research has identified persistent challenges that remain across the Ethiopian food system, from production to distribution to consumption. Production diversity and productivity are inhibited by limited access to appropriate inputs like fertilizer, improved crop seeds and animal breeds and agricultural technologies. Prices of nutrient dense foods have increased significantly over time making healthier diets unaffordable for the majority. Population growth and agricultural intensification has led to soil erosion, land degradation and deforestation. Besides, animal diseases, drought, flood and loss of crop yield due to pests are the challenges too that should be addressed through engagement of stakeholders representing the EU-Africa High Level Policy Dialogue Platform and to gather insights into the challenges often encountered by the farmers during production.

Rwanda

Historical cases

Rwanda is one of the most densely populated countries in Sub-Saharan Africa (SSA), with a population of 13 million people and a population density of 525 per km² [7]. Paradoxically, there is overwhelming evidence that off-farm employment is also dependent on agricultural sector productivity and income growth. Fortunately, while the industrial sector is responsive to capital growth, the agricultural sector is more responsive to technological innovations. Hence, sustainable solutions to productivity decline and food insecurity rely on pro-poor technology interventions. Despite this, African countries, especially those located in the eastern African region, have been facing unusual changes in their weather patterns, driven by climate change during the last few decades. Among the disasters, drought and flooding have caused significant crop loss, death of farm animals and damage to the ecosystem. Rwanda has made important development gains in food security and economic growth during the last two decades. However, due to disasters such as frequent drought, heavy rain, flooding, and disease outbreaks, the country has encountered low agricultural productivity leading to food insecurity, which in turn has an impact on people’s livelihoods [8]. Furthermore, the frequent occurrence of drought and flooding created favourable conditions for disease outbreaks like Rift Valley fever, cassava and other crop diseases, and foot and mouth disease, whose spread impacts the economic growth of the country. In view of this, identifying the major historical cases and understanding the conditions leading to their occurrence and trends are important to suggest possible prevention and adaptation strategies for building an agricultural resilience framework across the country and beyond. Ensuring sustainable agricultural development and economic growth under such prevailing challenges requires strong cooperation and partnership both among African countries and with other potential partners such as the EU. Consequently, the tables below present the major historical cases (both livestock and crop) which have significantly resulted in food supply disruptions, with possible mitigation measures, in Rwanda.

CS 4.31: Fish Death
Year of outbreak2016 and 2021
Affected regionMuhazi Lake (Rwamagana District, Munyiginya and Musha sectors) and Kayonza District (Kawangire sector), Eastern Province of Rwanda
Category affectedFish
DescriptionAfter physio-chemical parameter analysis, it was concluded that the cause of fish death was low dissolved oxygen in the water. The oxygen deficiency in this zone of Lake Muhazi was caused by an algal bloom, triggered some days before the event by wind mixing the deep, nutrient-rich water of the lake with the upper water. The minerals plus good sunshine caused a rapid development of algae (“algal bloom”). These phytoplankton produce oxygen during the day through photosynthesis but consume a lot of oxygen during the night. Consequently, the fish did not get enough oxygen and died.
Severity for the affected categoryHigh (100%)
Effect on the ecosystemHigh.
Severity for humansFood insecurity, depletion of households’ income.
Effects on economyLow productivity, decreased incomes.
Possible mitigation actions / CountermeasuresCheck different water parameters (dissolved oxygen, pH, temperature, NH4, NO3, and water transparency) on a daily basis; monitor phosphorus and nitrogen levels, since their high concentrations influence the fast growth of algae that the ecosystem cannot handle (“algal bloom”), which seriously reduces oxygen in the water. Move cages to give enough space between one cage and another to facilitate water exchange, which helps increase the oxygen level where DO has been observed as unsuitable for tilapia life. Reduce the stocking density in each cage. Harvest mature fish in the range of 500 g to 1 kg.
Possible prevention measures(1) Monitor the lake regularly (once a month) to record water parameters and limnological data at different layers of the lake, focusing mainly on sites with cage fish farming; (2) fast-track the inclusion of aquaculture in the subsidised insurance scheme, as with other agricultural and animal resource commodities; (3) develop cage fish farming guidelines for each lake (Kivu, Burera, Ruhondo, and Muhazi) recommended as suitable for cage fish farming in Rwanda; (4) monitor farms regularly to avoid exceeding the capacity of a given concession; (5) limit the number of fish farming projects in shallow lakes; (6) train farmers on water parameter monitoring and biosecurity measures for their projects.

Nigeria

Historical cases

Nigeria [9], whose national capital is Abuja, is located on the western coast of Africa with a diverse geography, with climates ranging from arid to humid equatorial. However, Nigeria’s most diverse feature is its people, with the country having abundant natural resources, notably large deposits of petroleum and natural gas. Despite the country being a leader in various types of agricultural production, such as palm oil, cocoa beans, pineapple, and sorghum, and being a large global exporter in this sector — oil, fruits, nuts, and seeds are among its ten best-performing export categories — the country’s agricultural sector faces many challenges which impact its productivity. Below are some of the documented historical case studies [10].

Historical case studies

CS 5.1: Fall Armyworm Infestation
Year of outbreak2016
Affected regionThe infestation affected many states in Nigeria, including Borno, Adamawa, Gombe, Bauchi, Taraba, Plateau, Kaduna, and Kano, among others.
Category affectedMaize, sorghum, millet, and other cereal crops.
DescriptionThe Fall Armyworm infestation is a destructive pest that attacks maize and other cereal crops. The larvae of the pest feed on leaves, causing significant damage to the plants and leading to a reduction in crop yield.
Severity for the affected categoryThe infestation caused significant damage to maize crops, with up to 50–80% yield losses reported in some areas.
Effect on the ecosystemThe infestation could have negative impacts on the cereal farming ecosystem, as it may disrupt the food web and affect other organisms that depend on the crops.
Severity for humansThe infestation had negative impacts on food security, as maize and other cereal crops are staple foods in many parts of Nigeria.
Effects on economyThe infestation could have negative impacts on the economy, as maize is a major crop in Nigeria, and the reduction in production could lead to increased prices for the crop.
Possible mitigation actions / CountermeasuresMitigation actions could include the use of pesticides, biological control measures, and cultural practices such as crop rotation and intercropping.
Possible prevention measuresPrevention measures could include the use of early warning systems, proper quarantine procedures, and the promotion of integrated pest management strategies.
More infoThe Fall Armyworm infestation is a global problem, estimated to have caused up to $3 billion in crop losses globally. The infestation was first reported in Nigeria in 2016 and has since spread to many other African countries. The Food and Agriculture Organization (FAO) of the United Nations has been working with governments and other stakeholders to help mitigate its impacts.
CS 5.2: Maize Lethal Necrosis
Year of outbreak2013
Affected regionThe disease has been reported in many states in Nigeria, including Plateau, Kaduna, and Kano, among others.
Category affectedMaize crops
DescriptionMaize lethal necrosis is a viral disease that affects maize plants, causing the leaves to become yellow and the plant to become stunted. The virus is spread by insects, and once a plant is infected there is no cure for the disease.
Severity for the affected categoryThe disease can cause significant damage to maize crops, leading to up to 100% yield losses in severe cases.
Effect on the ecosystemThe disease could have negative impacts on the ecosystem, as it may disrupt the food web and affect other organisms that depend on maize crops.
Severity for humansThe disease could have negative impacts on food security, as maize is a staple food in many parts of Nigeria. The reduction in maize production could also lead to increased prices for the crop.
Effects on economyThe disease could have negative impacts on the economy, as maize is an important crop in Nigeria, with the country being one of the largest producers of the crop in Africa. The spillover effects extend to animal feed production, as maize is a major input.
Possible mitigation actions / CountermeasuresMitigation actions could include the use of disease-resistant maize varieties, cultural practices such as removal of infected plants, and the use of insecticides to control the spread of the disease.
Possible prevention measuresPrevention measures could include the use of clean planting materials, the promotion of disease-resistant varieties, and the use of integrated pest management strategies.
More infoMaize lethal necrosis is a significant problem in many parts of sub-Saharan Africa, estimated to cause significant economic losses each year. The disease is a major threat to food security, as maize is an important staple food in many countries in the region. Efforts are ongoing to develop disease-resistant maize varieties and to promote integrated pest management strategies to help mitigate its impacts.
CS 5.3: Recurrent Flooding
Year of outbreakFloods are a recurring event in Nigeria; the country has experienced several major flood events in recent years, including in 2012 and 2020.
Affected regionFloods can affect many parts of Nigeria, but the areas most at risk are those located in low-lying areas and those close to rivers or other bodies of water.
Category affectedFloods can affect both crops and livestock, as well as infrastructure and homes.
DescriptionCaused by heavy rainfall or the overflow of bodies of water. Floods can cause significant damage to crops, livestock, and infrastructure, and can lead to loss of life and displacement of people.

Possible mitigation actions / CountermeasuresMitigation actions could include the adoption of integrated pest management strategies.
Possible prevention measuresFarmers opted for the use of tissue culture, so that quality, disease-free materials can be produced.

Risks

Nigeria faces multiple food security risks that challenge its agricultural resilience framework across three key categories: (i) sustainable intensification, (ii) agriculture and food systems for nutrition, and (iii) expansion and improvement of agricultural markets and trade. Climate change and variability, land degradation, and pest and disease outbreaks threaten sustainable intensification efforts by impacting crop yields and water availability. Malnutrition and micronutrient deficiencies are pressing issues within the agriculture and food systems for nutrition, stemming from limited dietary diversity and inadequate consumption of nutrient-rich foods. Furthermore, post-harvest losses, limited access to credit and financing, and infrastructure deficits hinder the expansion and improvement of agricultural markets and trade. Addressing these risks is crucial to building a more resilient and sustainable agricultural sector in Nigeria, ensuring food security, and promoting economic growth. In the following tables, we highlight some of these risks.

Kenya

Historical cases

Kenya [11] is a country located in East Africa, bordering the Indian Ocean to the southeast. The country is known for its diverse wildlife and scenic landscapes. The climate of Kenya varies depending on the region: generally, the coastal areas are hot and humid, while the highlands are cooler. The country has two rainy seasons — the long rains from March to May and the short rains from October to December [12]. Kenya is a major producer of tea, coffee, and horticultural products like flowers, fruits, and vegetables.

Historical case studies

CS 6.1: Locust
Year of outbreak2020
Affected regionMultiple regions
Category affectedAgricultural sector
DescriptionIn 2020, countries in the Horn of Africa as well as surrounding countries in the Middle East and even India faced a deadly locust infestation. Rainy conditions, climate change, unfortunate wind directions and COVID-19 meant the perfect conditions were created for locusts to breed, creating a nearly uncontrollable infestation.
Severity for the affected categoryThe severity of the infestation was almost the worst seen in 75 years in the region of Kenya.
Effect on the ecosystemPesticides used to keep the locust population under control contained chemicals harmful to humans. Articles estimate that more than 95% of the pesticides used to combat the locusts contained chemicals harmful to human health, noting the use of chlorpyrifos — a chemical banned in the EU due to causing brain damage in people and even foetuses on contact.
Severity for humansPesticides used against locusts contain chemicals harmful to humans and foetuses. Locusts damaged crops, furthering food insecurity and negatively impacting the agricultural economy in countries where the outbreak was prevalent. Rainy conditions and flooding in the Indian Ocean at the time furthered the issue by creating the perfect conditions for locusts to breed. The added strain of COVID-19 at the time also worsened the negative impacts.
Effects on economyEconomic issues, particularly in the agricultural sector, as many farmers lost their crops. COVID, flooding, droughts and pest issues all occurring consecutively meant the scale of the issue was hard to deal with. Crop decline for a few years due to different reasons pushed more people into food insecurity in the region, and also increased the cost of goods as demand for food was not being met.
Possible mitigation actions / CountermeasuresUse of biopesticides to reduce impact on human health and surrounding ecosystems.
Possible prevention measuresUse of chemicals that promote the plant’s natural defence mechanisms to deter pests, e.g. chitin, or the use of species competitive with locusts, which helps reduce damage to non-target species.
More infoAlternative methods of administering pesticides to better target an area and avoid damage to the wider ecosystem, being careful not to use groundwater-contaminating chemicals near water sources, for instance.
CS 6.2: Flood
Year of outbreak2020
Affected regionMultiple regions
Category affectedAgricultural sector
DescriptionThe downpour caused flooding in many areas as rivers such as the Nzoia broke their banks, forcing people to flee, and rivers like the Turkana flooded nearby land. The rains also loosened the earth and caused landslides in some areas, damaging land.
Severity for the affected categoryHigh
Effect on the ecosystemFlooding damaged infrastructure and animal habitats and left a lot of arable land unusable. Harmful animals such as poisonous snakes were displaced from their habitats and forced to encroach into spaces where humans dwell, causing further problems. Flooding in quick succession meant animals were left unable to cope with rapid changes in climate, so many species are currently struggling with loss of habitat and food chain damage.
Severity for humansThe effects of the flooding left an estimated 40,000 people homeless and a further 116,000 people displaced. Landslides caused by flooding damaged infrastructure, reducing access to essential services such as hospitals. Loss of crops and livestock due to flooding also pushed people further into food insecurity.
Effects on economySignificant funds were required to repair flood damage to infrastructure. Loss of crops meant the agricultural sector took a massive hit, and agriculture is the biggest sector of Kenya’s workforce. This pushed more people into food insecurity and placed pressure on the government to alleviate stresses caused by food insecurity and displacement due to weather conditions.
Possible mitigation actions / CountermeasuresUse of alternative water sources to accommodate for times of drought, e.g. purifying water from the sea.
Possible prevention measuresUse of flood barriers around lakes and rivers that are likely to burst their banks during periods of heavy flooding.
More infoGMO plants / use of chemicals that can help boost plants’ defences against pests, to help reduce competition for remaining crops after flooding.
CS 6.3: Drought
Year of outbreak2020–2022
Affected regionMultiple regions
Category affectedAgricultural sector
DescriptionThe ongoing drought in Kenya has caused issues for people, animals and the economy. The drought between 2020–2022 is among the worst Kenya has ever faced.
Severity for the affected categoryHigh
Effect on the ecosystemThe environment is also under threat from these unpredictable changes, as animals in the ecosystem struggle to keep up with rapid weather shifts.
Severity for humansCrop shortages caused by the drought have put nearly 2.1 million Kenyans at risk of starvation and projected a 50% crop loss for maize (Kenya’s most staple food source). Loss of crops due to drought also pushed people further into food insecurity. For almost five consecutive harvest seasons, farmers have struggled to get good crop yields due to pressures from locusts, other pests, and climate issues. Lack of water and food sources has also caused livestock populations to decline, with some farmers losing all their livestock to the drought.
Effects on economyLoss of crops meant the agricultural sector took a massive hit, and agriculture is the biggest sector of Kenya’s workforce. This pushed more people into food insecurity and placed pressure on the government to alleviate stresses caused by food insecurity and displacement due to weather conditions. Climate hazards are estimated to have knocked 3% off Kenya’s economy, with signs that unpredictable climate conditions will only become more severe.
Possible mitigation actions / CountermeasuresUse of alternative water sources to accommodate for times of drought, e.g. purifying water from the sea.
Possible prevention measuresUse of alternative water sources to accommodate for times of drought, e.g. purifying water from the sea.

CS 6.4: Maize Lethal Necrosis
Year of outbreak2021
Affected regionKenya, with significant reports from the Rift Valley, Nyanza, and Western regions
Category affectedAgricultural sector / maize crop
DescriptionMaize Lethal Necrosis is a viral disease that affects maize plants, causing severe symptoms including yellowing and stunting. The disease is spread by insect vectors, primarily thrips and leafhoppers. Infected plants exhibit chlorosis, necrosis, and in many cases, plant death. No cure is available once a plant is infected.
Severity for the affected categoryThe disease has caused significant yield losses in maize crops, with some areas experiencing up to 100% loss in severe cases.
Effect on the ecosystemThe outbreak led to disruptions in the ecosystem, particularly affecting species that rely on maize as a food source. The reduction in maize availability could have cascading effects on the food web.
Severity for humansThe impact on humans was profound, as maize is a staple food in Kenya. The disease led to food insecurity, higher maize prices, and economic strain on households.
Effects on economyThe economic impact was severe due to maize’s central role in Kenya’s agriculture. Significant losses were reported, affecting not just farmers but also industries dependent on maize, such as animal feed production.
Possible mitigation actions / CountermeasuresMitigation included the introduction of disease-resistant maize varieties, implementing strict cultural practices like removal of infected plants, and the use of insecticides to control the vectors.
Possible prevention measuresPrevention measures focused on the use of certified clean planting materials, promoting resistant varieties, and integrated pest management strategies to reduce the spread of the disease.
More infoMLN continues to be a significant threat to maize production in Kenya and other parts of sub-Saharan Africa. Ongoing research aims to develop more resistant maize varieties and improve management practices to mitigate future outbreaks.
CS 6.5: Foot-and-Mouth Disease (FMD) Outbreak in Kenya in 2003
Year of outbreak2003
Affected regionMultiple regions across Kenya, with significant reports from Rift Valley, Central, and Eastern provinces
Category affectedLivestock, particularly cattle, sheep, and goats
DescriptionFoot-and-Mouth Disease (FMD) is a highly contagious viral disease affecting cloven-hoofed animals, including cattle, sheep, and goats. It is characterized by fever, blisters in the mouth and on the feet, lameness, and reduced milk production in dairy animals. FMD can spread rapidly through contact with infected animals, contaminated equipment, or even through the air.
Severity for the affected categoryThe outbreak led to widespread infection in livestock, causing significant losses in meat and milk production. Infected animals often experienced severe weight loss, and some died if not managed properly.
Effect on the ecosystemThe disease can have a significant impact on the ecosystem, particularly in regions where livestock play a crucial role in the agricultural economy. The outbreak can disrupt the balance of grazing lands and affect other wildlife that may come into contact with infected animals.
Severity for humansAlthough FMD does not typically affect humans, the outbreak had severe indirect effects on human populations, particularly pastoralist communities that rely heavily on livestock for their livelihoods. The outbreak led to food insecurity, reduced income, and increased poverty in affected areas.
Effects on economyThe economic impact was substantial, as livestock are a critical component of Kenya’s agricultural sector. The outbreak led to trade restrictions, loss of livestock productivity, and significant financial losses for farmers. The ripple effects extended to industries such as dairy production and meat processing.
Possible mitigation actions / CountermeasuresMitigation strategies included mass vaccination campaigns, movement restrictions for livestock, culling of infected and exposed animals, and public awareness campaigns to educate farmers about the importance of disease control measures.
Possible prevention measuresPrevention measures focused on maintaining regular vaccination schedules, enforcing quarantine protocols for new or returning animals, and improving biosecurity measures at the farm and community levels.
More infoFoot-and-Mouth Disease remains a significant threat to livestock in Kenya and other parts of Africa. Ongoing efforts aim to improve vaccination coverage and enhance disease surveillance systems to prevent future outbreaks [13] [14].
CS 6.6: Desert Locust Invasion
Year of outbreak2020
Affected regionWidespread across Kenya, including Northern, Eastern, and Rift Valley regions
Category affectedCrops and rangelands
DescriptionThe 2020 locust invasion in Kenya was one of the worst in decades. Desert locust (Schistocerca gregaria) swarms, driven by unusual weather patterns and favorable breeding conditions, devastated crops and pasturelands. The locusts consumed large quantities of vegetation, including staple crops like maize, sorghum, and millet, as well as grazing areas vital for livestock. The invasion posed a severe threat to food security and livelihoods, particularly in arid and semi-arid regions.
Severity for the affected categoryThe locust swarms caused widespread destruction of crops and rangelands, leading to significant losses in food production and pasture. Some areas reported near-total destruction of crops, with millions of hectares of farmland and grazing land affected. The impact was particularly severe in regions already facing food insecurity.
Effect on the ecosystemThe locust invasion led to significant ecological disruptions, including loss of vegetation cover, which impacted soil health and biodiversity. The destruction of rangelands affected wildlife and livestock, leading to competition for remaining food resources. The large-scale use of pesticides to control the locusts also raised concerns about environmental and human health.
Severity for humansThe invasion severely impacted food security, particularly for pastoralist and farming communities. With the destruction of crops and grazing lands, many households faced food shortages, increased malnutrition rates, and economic hardship. The invasion also exacerbated poverty and led to displacement in some affected areas.
Effects on economyThe economic impact was substantial, with losses estimated in the hundreds of millions of dollars. The agriculture sector, a critical component of Kenya’s economy, was hit hard, leading to reduced crop yields, loss of livestock, and increased food prices. The government had to allocate significant resources for emergency response and locust control efforts, straining an already stretched budget.
Possible mitigation actions / CountermeasuresMitigation actions included aerial and ground spraying of pesticides to control the locust swarms, monitoring and early warning systems to track locust movements, and the deployment of international assistance to support local efforts. Farmers were also advised to implement adaptive strategies such as planting fast-maturing crops and diversifying income sources.
Possible prevention measuresPrevention measures focused on enhancing regional cooperation for locust surveillance and control, improving early warning systems, and investing in research to develop more effective and environmentally friendly locust control methods. Strengthening community resilience through diversification of livelihoods and improved land management practices was also emphasized.
More infoThe 2020 locust invasion highlighted the vulnerability of agricultural systems to climate-related events and the importance of international collaboration in managing transboundary pests. Ongoing efforts are needed to build resilience against future invasions. [Source: FAO, 2020; World Bank, 2020]
CS 6.7: Cassava Brown Streak Disease (CBSD)
Year of outbreak1990s, with increasing severity in subsequent years
Affected regionInitially reported in coastal regions, later spreading to other parts of Kenya, including Western and Nyanza regions
Category affectedCassava crops
DescriptionCassava Brown Streak Disease (CBSD) is a viral disease caused by the Cassava Brown Streak Virus (CBSV). It affects cassava plants by causing necrosis of the root tissue, resulting in brown streaks within the roots that make them unmarketable and unfit for consumption. Above-ground symptoms include chlorosis, leaf distortion, and stem lesions. The virus is primarily spread through infected planting material and by whitefly vectors (Bemisia tabaci).
Severity for the affected categoryCBSD can cause severe yield losses, particularly in root quality, with some affected areas experiencing up to 70% losses in marketable cassava roots. Infected plants may produce roots unfit for consumption or sale, significantly impacting both food security and income.
Effect on the ecosystemThe outbreak disrupts the agricultural ecosystem, particularly in areas where cassava is a staple crop. The disease can lead to abandonment of cassava cultivation, reducing plant diversity and affecting soil health. The reduction in cassava availability can also disrupt local food chains and negatively impact other species that rely on cassava as a food source.
Severity for humansThe disease poses a serious threat to food security in regions where cassava is a major staple. The loss of cassava crops due to CBSD leads to food shortages, increased malnutrition, and economic hardship for farming communities. The reduced availability of cassava also drives up prices, further straining household food budgets.
Effects on economyThe economic impact of CBSD is significant, particularly in regions where cassava is a primary cash crop. The disease leads to reduced income for farmers, increased costs for disease management, and losses in both local and export markets. Broader effects include reduced agricultural productivity, increased poverty in affected regions, and strain on local and national food systems.
Possible mitigation actions / CountermeasuresMitigation actions include the development and deployment of disease-resistant cassava varieties, the use of clean planting materials, and integrated pest management practices to control whitefly populations. Extension services are crucial for educating farmers on disease recognition and management practices. Rapid response measures, such as removal and destruction of infected plants, are also essential to controlling the spread of the disease.
Possible prevention measuresPrevention measures focus on the use of certified disease-free planting materials, regular monitoring and early detection of the disease, and the promotion of resistant cassava varieties. Implementing strict quarantine measures and improving the distribution of clean seed systems are also vital in preventing the spread of CBSD.
More infoCBSD continues to be a significant threat to cassava production in Kenya and across sub-Saharan Africa. Ongoing research and development efforts are focused on breeding more resistant cassava varieties, improving disease management practices, and enhancing farmer education to prevent and control future outbreaks [15].

Risks

Kenya has many similarities in risks on food security mainly with Ethiopia, Uganda and Rwanda. Thus, we can highlight, without explicitly replicating, the following food security risks:

Risk FS2.1.1: Inadequate Pest and Disease tolerant and resistant varieties
Risk FS2.2.1: Livestock Feed Shortage and Coping Mechanisms
Risk FS2.2.2: Poor breed performance
Risk FS2.2.3: Zoonotic disease challenges
Risk FS3.2.2: Scarcity of water and feed for animals
Risk FS3.2.3: Low adoption of animal breeding technologies and under-performing breeds
Risk FS4.1.3: High pressure of pests and diseases
Risk FS4.1.9: Climate change and weather variability

Nevertheless, especially for Kenya, one of the main risks is the scarcity of water (FS3.2.2) and climate change (FS4.1.9), which have led to unpredictable weather patterns, droughts, and floods that affect agricultural production. Another risk is the over-reliance on rain-fed agriculture, which also contributes to low productivity and food insecurity [36]. Over 80% of Kenya’s lands are classified as arid and semi-arid land (ASAL), based on the relatively low amounts of annual rainfall received. The Integrated Food Security Phase Classification (IPC) analysis in Kenya focuses on 23 counties/territories (following Table ) that comprise the Arid and Semi-Arid Lands (ASAL) region and whose population is generally the most food insecure given the high level of poverty, high vulnerability to shocks and hazards, particularly climatic shocks linked to rainfall variability [37]. In 2023, corresponding with the harvest season, the Acute Food Insecurity IPC analysis results indicated that out of the 23 counties/territories analysed, 12 are in IPC AFI Phase 3 (Crisis) while the remaining 11 counties are classified in IPC Phase 2 (Stressed). For this analysis, around 4.4 million (27% of the analysed population) are estimated to be in IPC Phase 3 (Crisis) or above. This includes around 774,000 (5%) people in IPC Phase 4 (Emergency) and 3.6 million (22%) in IPC Phase 3 (Crisis). Five counties reported over 50% of their population in IPC Phase 3 or above: Turkana (50%), Garissa (55%), Mandera (55%), Marsabit (55%), and Wajir (55%), which are predominantly pastoral livelihood zones. Latest data shows a likely unprecedented deterioration in Kenya’s food security situation, with over 5.4 million people experiencing acute food insecurity. In the current period, corresponding to the short rain harvest season, a slight decrease in the severity of food insecurity is observed across Kenya’s arid and semi-arid lands (ASAL) areas, which presented four counties in IPC AFI Phase 4 (Emergency) in the previous season (namely Isiolo, Turkana, Marsabit and Mandera) that improved to IPC Phase 3 (Crisis). This is mainly due to the direct impact of the rains on livelihoods in these areas. However, the improvement is expected to be limited in time, and further deterioration is projected in 2023. The provisional alleviation of food insecurity conditions in these areas, however, did not translate into an improvement to the Extremely Critical level (IPC AMN Phase 5) of acute malnutrition in parts of Marsabit (Laisamis) and Turkana South, and other areas, like North Turkana, Wajir and North Horr, are also projected to reach Extremely Critical levels of acute malnutrition.

Yet, in 2024 the severity of food insecurity is expected to worsen again: about 5.4 million people (32% of the population analysed) are projected to face high levels of acute food insecurity (IPC AFI Phase 3 or above), of which 1.2 million people (7%) will likely be in Emergency. This latest projection represents the highest magnitude and severity of acute food insecurity in the ASAL areas in years; urgent action is required to reduce food gaps, protect livelihoods, and prevent and treat acute malnutrition (Figure below).

In addition, pests and diseases pose a serious threat to food security, with invasive pests like the fall armyworm, Tuta absoluta and desert locusts causing significant damage to crops. Poor infrastructure, such as inadequate storage facilities and poor transportation networks, also puts Kenya’s food security at risk by causing post-harvest losses and reducing access to markets.

Finally, inadequate policies and regulations to guide the food sector and inadequate investment in research and development may hamper the implementation of Kenya’s food security roadmap. The COVID-19 pandemic has had a significant impact on food security, leading to supply chain disruptions, reduced incomes, and increased prices of food items, particularly for the vulnerable population. Overall, addressing these risks is crucial for successful implementation of Kenya’s food security roadmap.
