Riesgos climáticos y vulnerabilidades de El Salvador

Climate risk and vulnerabilities of El Salvador

El Salvador is exposed to a complex climate and multi-hazard risk environment shaped by its location in one of the world’s most seismically active regions, its volcanic and mountainous terrain, dense settlement patterns, degraded watersheds, and high dependence on climate-sensitive livelihoods. The country faces recurrent risks from earthquakes, volcanic eruptions, floods, landslides, tropical storms, hurricanes, tsunamis, and droughts, particularly during El Niño conditions. Climate change is intensifying these risks through rising temperatures, irregular rainfall, more frequent drought stress, extreme rainfall events, water scarcity, ecosystem degradation, and heightened pressure on agriculture, food security, infrastructure, public health, and vulnerable communities.

1. Multi-hazard exposure

El Salvador is exposed to both geophysical and hydrometeorological hazards. The World Bank describes the country as being located in one of the world’s most seismically active regions and identifies major hazards including floods, landslides, tropical storms, tsunamis, volcanic eruptions, and droughts, especially during El Niño seasons. (World Bank)

Earthquake risk is particularly important. GFDRR estimates annual average loss from earthquakes at about US$175.93 million, equivalent to 0.70% of GDP, and states that earthquake risk is more significant than hurricane risk in El Salvador. The same profile estimates that a 250-year return-period earthquake could generate losses of about US$3.9 billion, or 15.5% of GDP.

2. Disaster impacts and exposed population

Disasters have had major economic and human impacts in El Salvador. GFDRR reported that, between 1982 and 2007, natural disasters caused about US$4.57 billion in damages, with earthquakes, storms, floods, and droughts accounting for the largest reported losses. GFDRR also reported that around 41% of the population lived in municipalities exposed to high disaster risk, and those municipalities accounted for 74% of disaster-related fatalities.

This means disaster risk is not only an emergency-management issue; it is also a development, fiscal, infrastructure, poverty, and territorial-planning challenge.

3. Climate change as a risk multiplier

Climate change is increasing El Salvador’s vulnerability by altering rainfall patterns, intensifying drought stress, increasing heat exposure, and worsening the impacts of extreme rainfall. The country forms part of the Central American Dry Corridor, where erratic rainfall, recurrent drought, environmental degradation, and low crop yields create high climate vulnerability. (PreventionWeb)

The Green Climate Fund notes that in El Salvador, freshwater availability is already below a critical threshold, while rainfall variability, temperature, and extreme weather are projected to increase. It also links warming temperatures, severe drought, deforestation, and land degradation to water stress in agriculture and threats to food security. (Green Climate Fund)

4. Key climate vulnerabilities

Agriculture, food security, and rural livelihoods

Agriculture and rural livelihoods are highly climate-sensitive, especially in dryland and degraded watershed areas. Drought, irregular rainfall, soil erosion, land degradation, pests, crop failure, and reduced water availability directly affect smallholder farmers, rural workers, and food-insecure households. Climate-fragility analysis highlights how irregular rainfall, drought, environmental degradation, and low yields interact with poverty, migration, and human insecurity. (PreventionWeb)

Water security

Water scarcity is one of El Salvador’s most critical climate vulnerabilities. The country is not necessarily water-poor in absolute terms, but dry-season scarcity, degraded watersheds, deforestation, pollution, poor recharge conditions, and rainfall variability create serious pressure on households, agriculture, ecosystems, and urban water systems. The Dry Corridor context makes water-resource management central to adaptation. (Green Climate Fund)

Floods and landslides

Flood and landslide risks are driven by intense rainfall, steep volcanic slopes, unstable soils, watershed degradation, deforestation, poor drainage, and settlement in high-risk areas. Heavy rainfall can trigger flash floods, river overflow, debris flows, slope failure, damage to roads and bridges, disruption of schools and health facilities, and displacement of vulnerable households.

Seismic and volcanic vulnerability

El Salvador’s earthquake and volcanic risk remains a major threat to lives, housing, schools, hospitals, roads, water systems, and other critical infrastructure. Vulnerability is particularly high where older buildings, informal settlements, public facilities, and poorly enforced construction standards overlap with high seismic exposure. The World Bank has supported seismic risk mitigation for public school infrastructure because school safety is a major risk-reduction priority. (World Bank)

Urban and infrastructure vulnerability

Urban areas are vulnerable to flooding, poor drainage, landslides, slope instability, riverbank erosion, and earthquake damage. Roads, bridges, public buildings, schools, hospitals, water networks, and drainage systems are exposed to cascading impacts from both climate-related and geophysical hazards.

Social vulnerability

The most vulnerable groups include poor households, informal settlers, smallholder farmers, landless rural workers, women-headed households, children, older persons, people with disabilities, migrants, and communities living in flood-prone, landslide-prone, drought-prone, or degraded areas. A World Bank analysis found that around 34% of households are vulnerable to poverty because they are not currently poor but are exposed to hazard events that could push them into poverty. (World Bank)

6. Priority resilience needs

El Salvador’s climate and disaster resilience agenda should prioritize multi-hazard early warning systems, flood and landslide forecasting, seismic risk reduction, resilient school and health infrastructure, watershed restoration, climate-resilient agriculture, drought-risk management, water-security planning, risk-informed land-use zoning, ecosystem-based adaptation, disaster risk financing, and shock-responsive social protection.

Agencia de Protección Civil

Protección Civil es un servicio público, responsable de prevenir, mitigar y atender en forma efectiva los desastres naturales y antrópicos en el país y además desplegar en su eventualidad, el servicio público de protección civil, el cual debe caracterizarse por su generalidad, obligatoriedad, continuidad y regularidad, para garantizar la vida e integridad física de las personas, así como la seguridad de los bienes privados y públicos.

Institutional Framework

Civil Protection is a public service, responsible for preventing, mitigating and effectively addressing natural and man-made disasters in the country and also deploying, in the event of such disasters, the public civil protection service, which must be characterized by its generality, obligation, continuity and regularity, to guarantee the life and physical integrity of people, as well as the security of private and public property.

LEGAL BASIS:

The new Civil Protection, Prevention and Mitigation of Disasters Law in El Salvador was approved by decree No. 777 of August 18, 2005, and was published in the Official Gazette Volume No. 368, number 160. This Law replies the Civil Defense Law issued on April 8, 1976, as well as the Law of Procedures to declare a national emergency issued on July 29, 1988.

MISSION:

To coordinate the development of the country’s capacities for the comprehensive management of disaster risks, through the articulation of the National System of Civil Protection, Prevention and Mitigation of Disasters, which contributes to safeguarding human life in risk situations and the well-being of the inhabitants of the country, as well as safe and sustainable development.
