Mexico is one of the world’s most vulnerable countries to climate change.
The climate of Mexico has shifted dramatically over the last few decades, with an increase in extreme weather events and natural disasters. Climate change has increased environmental disasters, droughts, and floods.
The country is taking steps to mitigate these effects by utilizing renewable energy sources, but it is not yet sufficient.
This guide will highlight how Mexico’s vulnerability to climate change affects its regions, what steps it has taken so far to combat these effects, and what the global community can do to help Mexico succeed in this endeavor.
The impacts of climate change on Mexico
Mexico’s climate has changed dramatically over the last few decades, and it continues to be vulnerable.
A World Bank study report detailed how climate change has uniquely affected each region of Mexico. Droughts and decreased crop yields have impacted the North. In contrast, increased flooding has impacted the Center-West, stronger hurricanes have affected the South, and sea levels and coastal erosion are affecting the Yucatan Peninsula.
These events have resulted in fatalities, infrastructure damage, citizen displacement, and adverse economic consequences.
Mexico has taken measures to mitigate these effects. The country is emphasizing the expansion of renewable energy sources such as solar and wind power. These projects have been successful in the North of Mexico, but more work is needed throughout the country.
Mexico’s high-climate-impact zones
- The North: The effects of climate change have been most severe in Mexico’s North. Drought and low crop yields have resulted in food insecurity and loss of life. Wildfires are also on the rise in the region.
- The Center-West: Flooding has increased in the Center-West of Mexico, causing infrastructure damage and displacing people.
- The South: In recent years, the South of Mexico has seen more intense hurricanes that have destroyed communities and taken lives.
- Yucatan Peninsula: The Yucatan Peninsula is experiencing significant climate change impacts because of its geographical location. Because of melting ice caps, sea levels are rising, putting coastal areas at risk of flooding. As a result, many people in these communities have lost their homes and livelihoods.
The sustainability of Mexican cities
According to The Economic Commission for Latin America (ECLA), Mexico has the greatest impact from natural disasters.
This has increased its vulnerability to disasters such as earthquakes, landslides, droughts, and hurricanes, all of which are expected to become more severe as a result of climate change. Mexico’s vulnerability to climate change is also exacerbated by a lack of infrastructure, poverty, and social inequality.
The North-Central region of Mexico is one of the most affected by climate change. Water availability has decreased as a result of decreased precipitation and an increase in temperature. This has increased competition for water resources and has had an impact on agriculture. Maize production has decreased, despite the fact that it is an important staple food in the region.
Another region facing severe climate change risks is the Gulf of Mexico. The area is vulnerable to hurricanes, which are becoming more powerful as a result of climate change. This endangers coastal communities and the tourism industry.
Climate change is also posing severe threats to the Yucatan Peninsula. Temperatures have risen while rainfall has decreased, resulting in a decrease in water availability. This has an impact on agriculture and is causing issues with the drinking water supply.
Mexico is taking action to address the threats posed by climate change. The country has created a National Climate Change Strategy to reduce greenhouse gas emissions and increase adaptive capacity. Mexico is also a signatory to the Paris Agreement, which commits countries to reduce emissions to limit global temperature rise to less than two degrees Celsius.
Climate change and its potential impacts on Mexico’s health
Climate change is already having an impact on the health of Mexicans, and this trend is expected to continue. Mexico’s most vulnerable regions to climate change include those with high levels of poverty and inequality, as well as areas prone to natural disasters.
Climate change’s health effects can be divided into two categories: direct and indirect effects.
Direct health effects include the spread of infectious diseases as temperatures rise, an increase in respiratory illnesses as air quality deteriorates, and water-related risks such as diarrhea caused by flooding or a lack of access to safe drinking water.
In addition to the direct effects of climate change on public health, changes in the location and severity of storms, floods, and droughts can have an indirect impact on health. People have been displaced, property and livelihoods have been lost, food insecurity and malnutrition have increased, and psychological stress has been reported.
For many years, the Mexican government has worked to address the public health impacts of climate change.
It was one of the first countries to develop a national climate change policy in 2007, and it released an integrated health sector response plan in 2009. Since then, numerous additional initiatives have been implemented across various government sectors to address both direct and indirect impacts on public health.
The Mexican government has also considered national priorities for mitigating climate change (including lowering greenhouse gas emissions) and adapting to its health effects.
Mexico City’s air quality, weather, and climate
Mexico is located on the continent of North America. The country has a total population of about 124 million people, with nearly half of them living in cities near Mexico City known as urban agglomerations. Ciudad Nezahualcóyotl and Ecatepec de Morelos, both in the state of Mexico, are examples of urban agglomerations.
The International Development Research Centre (IDRC) published a study on Mexico City’s air quality and its effects on human health. The researchers discovered a link between certain pollutants in the city’s atmosphere at different times of day and their impact on cardiovascular disease events.
The researchers discovered that while cardiovascular disease events were most common during the day, their frequency increased significantly at night. The researchers concluded that this was due to higher concentrations of particulate matter in Mexico City’s atmosphere at night when compared to levels recorded on days when cardiovascular disease events were more common.
Mexican agriculture and global warming
Extreme weather events have become more common in Mexico as the world has warmed. There were three times as many days with temperatures above 100 degrees Fahrenheit between 1996 and 2005 as any other time period on record.
The rise in global temperature is also making it more challenging to grow crops in previously temperate areas. According to a recent study, the maize crop in central Mexico will likely decline by up to 50% as a result of global warming.
This is a significant issue because maize accounts for nearly one-third of all calories consumed in Mexico.
Crops are becoming more challenging to grow, and changes in weather patterns are causing pests and diseases to spread more quickly. Because of warmer temperatures and increased rainfall, the coffee rust fungus, for example, has spread throughout Mexico.
Climate change has far-reaching consequences that go beyond agriculture. Sea-level rise is endangering coastal communities, and changes in precipitation patterns are causing water shortages in many parts of the country.
Mexico has taken several steps to reduce carbon emissions and conserve water to address these challenges. By 2024, the country intends to generate 35% of its electricity from renewable sources while also improving energy efficiency in many homes.
The government is also attempting to improve farming practices to make them more resistant to changes in weather patterns caused by global warming. They have introduced new maize planting techniques and are working with farmers to put them into practice.
Mexico is not acting alone in its efforts to combat climate change. The United States, China, and the European Union have all pledged to cut their carbon footprints. On the other hand, Mexico has set some of the most ambitious goals of any country.
It will be a difficult task, but if Mexico achieves its objectives, it may serve as a model for other countries to follow.
