Bolivia's Climate Crisis: A Country's Struggle

Bolivia is a landlocked country in central South America, with a varied topography and a wide range of climates. The country is highly dependent on natural resources such as agriculture, mining, and hydrocarbons, which leaves it vulnerable to the effects of climate change. Bolivia has already experienced the impacts of climate change, including longer and more frequent droughts, floods, and storms, with negative consequences for agricultural yields and local livelihoods. Climate change is expected to exacerbate these issues, leading to increased water scarcity, more frequent and intense natural disasters, and a higher risk of mosquito-borne diseases and forest fires.

Water scarcity and security

Bolivia is one of the countries most affected by climate change, and this is having a profound impact on its water security. The country is already experiencing increasing water scarcity, with around three million people in rural areas lacking water security and five million without access to adequate sanitation.

The changing climate is causing more frequent and intense droughts, which are reducing water availability in the arid and semi-arid valleys and highland regions. This is particularly impacting areas that rely on rudimentary water systems using wells or rivers, as these systems are vulnerable to water availability and often lack reserves to last through the dry season. The reduction in glaciers due to global warming is also contributing to decreased water availability in the medium to long term.

At the same time, climate change is leading to more frequent and severe flooding, which can cause significant damage to infrastructure and agricultural yields. While regional scenarios predict a reduction in overall rainfall, there is also an increased probability of heavy rains during short periods, leading to intense flooding. The lack of early warning systems and integrated management of watersheds further increases the vulnerability of human populations, especially in unplanned settlements.

To address these challenges, the Bolivian government is working to improve water security and manage water resources more efficiently and sustainably. Initiatives such as the Integrated Rural Development at the River Basin Level (PROCUENCA) aim to bring together various stakeholders, including government ministries and local communities, to develop and implement climate-sensitive water management plans. These plans focus on protecting water resources from pollution and overuse, improving water security, and increasing the resilience of the population to the impacts of climate change on their water supply.

The social empowerment tool of "water committees" has also emerged as a grassroots solution to the water crisis. These committees gather and disseminate knowledge on water resource management, climatology, and emergency response, fostering a strong awareness of water culture and promoting sustainable and participatory access to water.

Extreme weather events

Bolivia is highly vulnerable to climate change, and extreme weather events are already impacting the country. In the past, Bolivia has experienced storms with winds above 100 km/h, violent hailstorms, droughts, floods, and forest fires. These events are projected to increase in frequency and intensity as the planet warms.

One of the key impacts of climate change in Bolivia is the increase in extreme hydro-meteorological events, such as storms and hailstorms. These events are expected to become more frequent and intense due to the impact of climate change. In the past, Bolivia has experienced storms with winds exceeding 100 km/h, as measured on the Beaufort scale, which have caused significant damage. The country has also witnessed violent hailstorms, such as those that occurred in La Paz in February 2002 and 2003. Under climate change scenarios, the conditions that fuel these extreme events are likely to become more favourable, increasing the likelihood of their occurrence.

Droughts are another pressing concern for Bolivia due to climate change. The country, particularly its arid and semi-arid valleys, already experiences water scarcity, and climate change is expected to exacerbate this issue. Many productive and urban areas in these arid regions rely on basic water systems, such as wells or rivers, which are highly vulnerable to water availability. As temperatures rise, evaporation rates increase, further reducing water availability and impacting both human and natural systems. The reduction in water availability also affects agricultural practices, threatening food security in the country.

Climate change is also predicted to bring more intense rains, leading to devastating floods. While regional scenarios suggest a reduction in overall rainfall, the intensity of rain during shorter periods is expected to increase. This shift towards more intense rainfall events will likely result in significant infrastructure damage and economic losses. The lack of early warning systems and rain pattern studies in Bolivia further increases the vulnerability of its human populations, especially those in unplanned settlements.

The impact of climate change on glaciers is also a significant concern for Bolivia. The Bolivian glacier Chacaltaya, located near La Paz, has lost a substantial portion of its surface area since 1982 and is projected to melt entirely. This glacier reduction will lead to increased seasonal runoff in the short term and heightened dependence on seasonal rains for water supply in the medium to long term.

The combination of these extreme weather events poses a severe threat to Bolivia's communities, particularly those in poverty and Indigenous groups. The impacts of these events extend beyond environmental damage, threatening livelihoods, stability, and lives. As temperatures rise and extreme weather events become more frequent and intense, the challenges of adapting to and mitigating the impacts of climate change in Bolivia become increasingly urgent.

Deforestation and forest fires

In 2022, Bolivia was ranked third in the world for primary forest loss, and this trend has continued, with a 32% increase in deforestation from 2021 to 2022. Most of this deforestation is happening in Santa Cruz, Bolivia's most economically dynamic region, driven by the expansion of agriculture, particularly soybean farming. The country's booming agribusiness is leading to more land being cleared for crops and livestock, and the slash-and-burn practice of chaqueo is commonly used to clear old vegetation and prepare the soil for planting.

However, the combination of deforestation and forest fires is exacerbating the impacts of climate change in Bolivia. The country is experiencing more frequent and intense droughts, and these dry conditions are fuelling the forest fires. In 2023, satellites detected widespread fire activity in Bolivia's lowlands, with nearly 7,761 active fires in a single day in October. These fires spread into natural ecosystems, including the Chiquitano forests, and the smoke became so heavy that schools had to be closed.

The forest fires are causing long-term damage to Bolivia's forests. While grasslands can recover quickly after a fire, tropical forests can take decades or longer to regenerate. The fires are also impacting local communities, with crops and grazing lands destroyed and towns threatened by the advancing fires.

The Bolivian government has declared a state of emergency in response to the severe fires, and the armed forces have been deployed to help fight the wildfires. However, with climate change intensifying droughts and heat waves, and deforestation continuing, Bolivia is facing a challenging situation that threatens its unique ecosystems and the livelihoods of its people.

Food security and farming

Bolivia is a landlocked country in central South America, with a varied topography and a wide range of climates. Agriculture, forestry, and fishing employ nearly 44% of its workers, and in the highlands region, most agricultural workers are engaged in subsistence farming.

Bolivia is particularly vulnerable to climate change due to widespread poverty, its variety of ecosystems, weather extremes, melting glaciers, and high deforestation rates. The impact of climate change on water availability and quality will have a significant effect on food security and farming in Bolivia.

The country has already experienced longer and more frequent droughts, floods, and storms due to climate change. These extreme hydro-meteorological events are expected to increase in magnitude and intensity. The increase in violent hailstorms has been observed in La Paz in 2002 and 2003, for example. Droughts, caused by a combination of higher temperatures and reduced rainfall, will likely become more frequent and intense, particularly in arid and semi-arid valleys and the highlands. This will impact water availability for both irrigation and livestock farming, reducing agricultural yields.

Climate change is also expected to lead to more intense rains and flooding, causing significant damage to infrastructure. While regional scenarios predict a reduction in overall rainfall, there is a probability of an increase in heavy rains during short periods. This will result in land degradation, a decline in aquifer recharge, and reduced water availability, all of which will negatively impact agricultural productivity and income for farmers.

Additionally, the reduction of glaciers due to global warming will increase seasonal runoff in the short term and increase dependence on seasonal rains for water in the medium to long term. The Bolivian glacier Chacaltaya, located near La Paz, has lost 82% of its surface area since 1982 and could have completely melted by 2013. This will further impact water availability for agriculture.

The impact of these changes on food security and farming is significant. Unpredictable weather patterns and water scarcity will make it difficult for farmers to plan and successfully grow crops, threatening their livelihoods, especially for small-scale and subsistence farmers. Women, who are often in charge of agricultural production and left to tend families and farms, are often the hardest hit, with fewer alternative livelihoods when crops are lost.

To address these challenges, Bolivia has developed strategies such as the National Climate Change Program and the National Adaptation Plan, which aim to reduce vulnerability to climate change and promote adaptation in various sectors, including food security. The country has also incorporated cross-cutting policies and programs into its National Development Plan to guarantee an early response to the impacts of climate change.

Glacier retreat and flooding

The impact of glacier retreat is already being felt in Bolivia. One of the most serious effects is the reduced water availability for Andean populations' agriculture, consumption, and ecosystems. Densely populated cities such as La Paz and El Alto are experiencing water shortages as demand outstrips supply. The retreat of glaciers also contributes to the overall challenge of climate change adaptation in the country.

The Bolivian Andes, specifically the Cordillera de Apolobamba, hold the largest continuous glaciated area in the country. This region has witnessed the formation of small and medium-sized lakes on the glacier terminus due to the retreat of glaciers. While these lakes can be picturesque, they pose a significant threat. Many of them are contained only by loose moraine debris, which means a breach could result in catastrophic flooding downstream.

The risk of GLOFs in Bolivia is not adequately addressed or monitored. There is a lack of documentation and awareness regarding these hazards, which has led to insufficient adaptation strategies. However, some progress has been made in recent years. Since 2008, the Global Environment Fund has financed a project implemented by the World Bank to mitigate the effects of glacier retreat and define costs. Small-scale risk assessments are also being conducted to demonstrate the benefits of more automated, water-conscious agriculture.

The future of Bolivia's glaciers is uncertain, but the current trends are concerning. The continued melting of glaciers will likely lead to further water scarcity issues and increase the risk of flooding events. Adaptation and mitigation strategies are crucial to address these challenges and protect vulnerable communities and ecosystems in Bolivia.
