WHO / UNFCCC Climate & Health Profile 2021

National Context

Country Background

Located on the eastern shore of the Mediterranean Sea, Lebanon’s territory is mostly mountainous with a land area of 10 452 km2 and a coastline of 225 km (1). The economy is dependent upon the service sector, which contributes 45% of the national GDP (2). While the agricultural sector accounts for only around 5% of GDP, agriculture has been impacted by higher world food prices and climate change, which could have significant implications for food security in Lebanon (2,3). Around 90% of Lebanon’s population lives in urban areas, especially in the big cities along the coast (1).

Lebanon’s climate is predominantly Mediterranean, with hot and dry summers from June to September and cool and rainy winters from December to March (1). Due to arid and semi-arid conditions, water resources are scarce and vulnerable to the effects of climate change and consequential changes in precipitation patterns (4). This threatens the agricultural sector, which is also pressured by population growth and urbanization (5). Further, climate change is expected to result in less snow, increased droughts, sea level rise and forest fires. Higher temperatures and frequent extreme events, such as droughts and floods, could lead to health risks such as infectious diseases, increased morbidity and mortality from heat stress, waterborne and vector-borne diseases (1). Encroaching seas are projected to expand seawater incursions into coastal freshwater aquifers and reduce the supply of freshwater for local use. Additionally, higher storm surges could increase damage to low-lying infrastructure and communities, and higher temperatures and reductions in annual precipitation could result in a hotter and drier climate, potentially diminishing future supplies of surface water.

Lebanon updated its Nationally Determined Contribution (NDC) in 2020, increasing its previous mitigation ambitions. The NDC commits unconditionally to reducing its greenhouse gas emissions by 20%, compared with the business-as-usual scenario, by 2030. Climate change is recognized as a threat multiplier in the NDC, which outlines numerous adaptation strategies, including implementing climate-resilient systems to ensure and protect public health, well-being and safety of all communities in Lebanon (4).

Current and Future Climate Hazards

Climate Hazard Projections for Lebanon

Country-specific projections are outlined up to the year 2100 for climate hazards under a ‘business as usual’ (BAU) high emissions scenario compared to projections under a ‘two-degree’ scenario with rapidly decreasing global emissions (see Figures 1–5).

The climate model projections given below present climate hazards under a high emissions scenario, Representative Concentration Pathway 8.5 (RCP8.5 – in orange) and a low emissions scenario (RCP2.6 – in green).a The text describes the projected changes averaged across about 20 global climate models (thick line). The figuresb also show each model individually as well as the 90% model range (shaded) as a measure of uncertainty and the annual and smoothed observed record (in blue).c In the following text the present-day baseline refers to the 30-year average for 1981–2010 and the end-of-century refers to the 30-year average for 2071–2100.

Modelling uncertainties associated with the relatively coarse spatial scale of the models compared with that of geographically small countries are not explicitly represented. There are also issues associated with the availability and representativeness of observed data for some locations.

Figure 1: Mean Annual Temperature, 1900-2100

Rising temperature

Under a high emissions scenario, the mean annual temperature is projected to rise by about 4.3°C on average by the end-of-century (i.e. 2071–2100 compared with 1981–2010). If emissions decrease rapidly, the temperature rise is limited to about 1.3°C.

Figure 2: Total Annual Precipitation, 1900-2100

Decrease in total precipitation

Total annual precipitation is projected to decrease by about 25% on average under a high emissions scenario, although the uncertainty range is large (-37% to -9%). If emissions decrease rapidly, there is little projected change on average: with a decrease of 3% and an uncertainty range of -17% to +4%.

Figure 3: Percentage of hot days ('heat stress'), 1900-2100

More high temperature extremes

The percentage of hot daysd is projected to increase substantially from about 15% of all days on average in 1981–2010 (10% in 1961–1990).
Under a high emissions scenario, about 65% of days on average are defined as ‘hot’ by the end-of-century. If emissions decrease rapidly, about 30% of days on average are ‘hot’. Similar increases are seen in hot nightsd (not shown).

Figure 4: Contribution of very wet days ('extreme rainfall' and 'flood risk') to total annual rainfall, 1900-2100

Small increase in extreme rainfall

Under a high emissions scenario, the proportion of total annual rainfall from very wet dayse (about 20% for 1981–2010) could increase slightly by the end-of-century (to about 23% on average with an uncertainty range of about 5% to 40%), with even less change if emissions decrease rapidly.
These projected changes are accompanied by decreases in total annual rainfall (see Figure 2).

Figure 5: Standardized Precipitation Index (Drought), 1900-2100

Drought frequency and intensity

The Standardized Precipitation Index (SPI) is a widely used drought index which expresses rainfall deficits/excesses over timescales ranging from 1 to 36 months (here 12 months, i.e. SPI12).f It shows how at the same time extremely dry and extremely wet conditions, relative to the average local conditions, change in frequency and/or intensity.

Under a high emissions scenario, SPI12 values are projected to decrease from about -0.3 to -1 on average by the end-of-century (2071–2100) indicating an increase in the frequency and/or intensity of dry episodes and drought events. If emissions decrease rapidly there is little change although year-to-year variability remains large.f

1. COMPLETE AND IMPLEMENT THE HEALTH AND CLIMATE CHANGE STRATEGY/PLAN CURRENTLY UNDER DEVELOPMENT FOR LEBANON

Complete the development of the national health and climate change plan. Assess barriers to implementation of the plan/strategy (e.g. governance, evidence, monitoring and evaluation, finance). Implementation can be supported by exploring additional opportunities to access funds for health and climate change priorities (e.g. GCF readiness proposal). See “WHO resources for action” for further details.

2. STRENGTHEN INTEGRATED RISK SURVEILLANCE AND HEALTH EARLY WARNING SYSTEMS

Meteorological information is not currently used to inform risk surveillance of climate-sensitive diseases. The use of climate/weather information can be integrated into health surveillance systems and used to predict outbreaks of climate-sensitive diseases (i.e. climate-informed health early warning systems) to help ensure a preventive approach to specific climate-sensitive health programmes.

3. ASSESS THE HEALTH CO-BENEFITS OF NATIONAL CLIMATE MITIGATION POLICIES

Health co-benefits of mitigation are currently not included in Lebanon’s Nationally Determined Contribution (NDC). Ensure that climate mitigation policies include the health risks posed from climate change, identify health adaptation priorities and measure and optimize the health co-benefits of climate mitigation action.

4. BUILD CLIMATE-RESILIENT AND ENVIRONMENTALLY SUSTAINABLE HEALTH CARE FACILITIES

Measures can be taken to prevent the potentially devastating impacts of climate change on health care facilities and health service provision while decreasing the climate and environmental footprint of health care facilities. A commitment towards climate-resilient, environmentally sustainable health care facilities can improve system stability, promote a healing environment and mitigate climate change impacts.
