Emergencies and disasters pose significant risks to all populations, but older persons often face heightened vulnerabilities due to physical, cognitive, and social factors. In Kenya’s community health context, protecting older persons during such events requires a clear understanding of what constitutes disasters and emergencies, as well as how these situations impact health and wellbeing. This chapter focuses on defining these critical concepts, laying a foundation for effective preparedness, response, and recovery strategies tailored to the needs of elderly populations in diverse Kenyan communities.

7.1 Define Disasters and Emergencies

Disasters and emergencies are terms frequently used interchangeably, yet they have distinct meanings that influence how community health professionals plan and implement protective measures. In Kenya, where natural hazards such as droughts and floods, as well as man-made crises like fires or disease outbreaks, occur regularly, precise definitions help in mobilizing appropriate resources and interventions. For community health workers involved in geriatric care, understanding these definitions is essential for identifying risks, coordinating with stakeholders, and ensuring that older persons receive timely support.

7.1.1 Disasters: Meaning and Characteristics

The term disaster refers to a serious disruption of the functioning of a community or society involving widespread human, material, economic, or environmental losses that exceed the affected community’s ability to cope using its own resources. This disruption often results in significant suffering and requires external assistance. In the Kenyan context, disasters can be natural or human-induced, and they challenge health systems, infrastructure, and social networks, especially impacting vulnerable groups such as older persons.

Characteristics of Disasters

• Sudden Onset and Severity: Disasters typically occur suddenly or escalate rapidly, overwhelming local capacities. For example, the 2018 floods in parts of Western Kenya displaced thousands, including elderly residents who lost homes and access to healthcare.

• Widespread Impact: Disasters affect large populations and geographical areas, disrupting essential services such as water supply, sanitation, and medical care, which are critical for older persons who may have chronic conditions.

• Resource Overload: The scale of damage exceeds local resources, necessitating external aid. County governments often rely on the National Disaster Operations Centre to coordinate relief during disasters.

• Long-term Consequences: Beyond immediate destruction, disasters have prolonged effects on health, livelihoods, and social structures. Older persons may face challenges including malnutrition, isolation, and exacerbation of chronic diseases.

• Multifaceted Nature: Disasters involve physical, social, economic, and environmental dimensions, requiring a multisectoral response. For instance, a drought affects food security, water availability, and disease patterns, all of which influence elderly health.

7.1.2 Emergencies: Definition and Types

An emergency is a situation that poses an immediate risk to health, life, property, or environment and demands urgent intervention but is generally more limited in scale and duration than a disaster. Emergencies can escalate into disasters if not managed promptly. Kenyan community health workers often encounter emergencies such as localized disease outbreaks, road traffic accidents, or fires within informal settlements where older persons live.

Types of Emergencies

• Medical Emergencies: Situations like strokes or heart attacks requiring immediate medical attention. Older persons are at higher risk due to pre-existing conditions.

• Natural Emergencies: Events such as landslides or flash floods that occur suddenly and threaten lives and infrastructure.

• Technological Emergencies: Incidents involving hazardous materials or power outages affecting health facilities and community services.

• Social Emergencies: Events such as civil unrest or displacement that disrupt social order and access to care.

• Environmental Emergencies: Pollution or contamination of water sources impacting health, particularly for elderly individuals dependent on clean water.

7.1.3 Differences Between Disasters and Emergencies

Understanding the distinction between disasters and emergencies helps community health professionals prioritize interventions and allocate resources effectively. While both require prompt action, the scale, duration, and resource demands differ significantly.

Key Differences

• Scale and Impact: Disasters affect larger populations and cause extensive damage, whereas emergencies tend to be localized and more manageable with existing resources.

• Resource Needs: Disasters overwhelm local capacities, requiring national or international assistance, whereas emergencies can often be handled by local agencies.

• Duration: Disasters have prolonged recovery phases, while emergencies are usually short-term events.

• Response Complexity: Disaster response involves coordination across multiple sectors and levels of government, while emergency response may be confined to health or safety services.

• Risk to Vulnerable Groups: Older persons may be at risk in both; however, disasters create systemic challenges that exacerbate vulnerabilities more severely.

7.1.4 Importance of Defining Disasters and Emergencies in Geriatric Care

Clear definitions are vital for designing appropriate preparedness and response strategies that address the unique needs of older persons. In Kenya, community health workers use these definitions to develop risk assessments, emergency plans, and training programs that ensure elderly populations receive tailored support during crises.

Reasons Defining Matters

• Targeted Risk Assessment: Knowing the nature of hazards enables identification of specific risks faced by older persons, such as mobility limitations during floods.

• Effective Resource Mobilization: Differentiating emergencies from disasters guides allocation of medical supplies, personnel, and shelter facilities suitable for elderly care.

• Communication and Coordination: Standardized terminology facilitates collaboration among health workers, county officials, and non-governmental organizations.

• Policy and Planning: Definitions inform national guidelines such as the Kenya National Disaster Response Plan that includes provisions for vulnerable groups.

• Training and Capacity Building: Health professionals receive focused training on managing geriatric needs in various crisis scenarios.

Chapter Summary

This chapter explored the definitions of disasters and emergencies, clarifying their nature as sudden events that disrupt normal life and require immediate action. It examined the various causes of these incidents, including natural phenomena and human activities that can lead to widespread harm. Different types of disasters and emergencies were described, highlighting their diverse characteristics and impacts on communities. The chapter emphasized the particular vulnerability of older persons in such situations, considering factors like reduced mobility, health conditions, and social isolation. It also addressed the importance of preparedness measures tailored to protect older individuals, ensuring their safety and well-being before, during, and after emergencies. Finally, effective response strategies were discussed, focusing on coordinated efforts to meet the specific needs of the elderly population during crises. This comprehensive understanding equips caregivers to better support older persons through all phases of disasters and emergencies.
