Avocado and Climate Change: How Global Warming is Affecting Avocado Production
With their creamy texture and rich taste, avocados have become a staple in diets worldwide. Beyond their culinary appeal, avocados play a significant role in the global economy, with countries like Mexico, the Dominican Republic, Peru, and Indonesia leading the production. However, the future of this beloved fruit is under threat due to climate change.
Avocado Production Today
Avocado production has seen significant growth in recent years. In 2021, the estimated total world production for avocados was 8,685,672 metric tonnes, up 7.2% from 8,104,028 tonnes in 2020. Mexico was the largest producer, accounting for over 28% of global production.
In the context of climate change, this growth in avocado production is noteworthy. Avocados are grown in a variety of locations across the globe, but they are sensitive to poor drainage and cannot tolerate standing water. They also cannot survive in a saline environment. Therefore, changes in rainfall patterns and rising sea levels, both consequences of global warming, could potentially impact avocado production.
Moreover, avocados can live and perform well in climatic circumstances ranging from real tropical to warmer areas of the temperate zone, depending on the race and variations. As global temperatures rise, the suitable areas for avocado cultivation may shift, which could have implications for future production.
In India, for example, West Indian, Guatemalan, and Mexican horticultural breeds adapted to tropical and sub-tropical environments were tested. Changes in climate could affect the suitability of these environments for avocado cultivation.
In the United States, California accounts for the majority of U.S. avocado production, followed by Florida and Hawaii. The value of U.S. avocado production measured $341.9 million in 2021. Changes in climate in these regions could also impact U.S. avocado production.
Overall, while avocado production is currently thriving, the effects of climate change could present challenges in the future. It’s crucial for producers and researchers to continue monitoring these changes and developing strategies to ensure the sustainability of avocado production in the face of a changing climate.
Impact of Climate Change on Avocado Production
Climate change, characterized by global warming, erratic rainfall patterns, and increased frequency of extreme weather events, is altering the ideal growing conditions for avocados.
For instance, avocados require a substantial amount of water, and the predicted decrease in rainfall due to climate change could severely impact their growth. Additionally, the rise in temperatures could make the current major production areas unsuitable for avocado farming.
In Mexico, the world’s largest producer of avocados, rising avocado prices have contributed to illegal deforestation. In Colombia, farmers who can no longer grow crops like avocados are among the most affected.
New research conducted by Zurich University shows that climate change may fundamentally impact the way avocados are grown. The study, which projects the agricultural future of these fruits, found that by the year 2050, avocado production will look vastly different from how it looks today. Climate change is impacting the soil where avocados are grown, like the Dominican Republic, Indonesia, and Peru. The Swiss university’s research shows that in 28 years, these areas will be less suitable for avocado growth.
However, there’s still plenty of research to be done that explains exactly how this will happen. This doesn’t mean that avocados will simply stop existing in 2050, but people — especially farmers — should expect the need to pivot. The researchers suggest growing the crops in locations with higher altitudes and focusing on adaptations like breeding plant varieties that can live more easily amidst rising temperatures and frequent droughts.
Predictions for the Future
If the current trends continue, avocado production could look very different by 2050. The traditional avocado-producing regions might struggle to maintain their output, while new regions, such as the United States, Argentina, China, and East Africa, could become major producers. However, these potential new regions will face their own challenges, including adapting to new crops and managing pests and diseases.
Adapting to Change
Adapting to climate change in the context of avocado farming involves several strategies:
- Relocation: Some farmers are considering moving their farms to higher altitudes, where temperatures are cooler. This is because avocados grow best in moderate temperatures, and higher altitudes can offer a cooler climate as global temperatures rise.
- Breeding New Varieties: Scientists and farmers are also investigating the possibility of breeding new varieties of avocados that can withstand the changing conditions1. This could involve developing strains of the fruit that are resistant to extreme temperatures.
- Irrigation Strategies: Implementing new irrigation strategies could be another way to adapt. As rainfall patterns change due to climate change, managing water resources effectively becomes crucial.
- Soil Enrichment: Enriching soils could help make them more suitable for avocado growth in changing climate conditions.
- Diversification: Farmers could also consider diversifying their crops. This could help ensure their farms remain productive even if avocado yields decrease due to climate change.
It’s important to note that these adaptation strategies require resources and support. Small growers who live from one harvest to the next may find it particularly challenging to implement these changes due to the costs involved. Therefore, policy support and funding for research and development in this area are crucial to help farmers adapt to climate change and ensure the sustainability of avocado production.
There are several innovative solutions being explored to tackle these challenges. For instance, climate-smart technologies are being developed that could transform the way we grow food, including avocados. These technologies include reducing tillage, expanding crop rotations, planting cover crops, and reintegrating livestock into crop production systems.
The future of the global avocado industry is at a crossroads due to climate change. Traditional avocado-producing regions may face significant challenges, while new regions could emerge as major producers. However, this transition will not be without its own set of challenges. Adapting to these changes will require innovative strategies such as relocating farms to higher altitudes, breeding new avocado varieties, implementing effective irrigation strategies, enriching soils, and diversifying crops. These strategies, however, require substantial resources and support, particularly for small growers. Therefore, policy support and funding for research and development are crucial. Additionally, the exploration of innovative solutions, such as climate-smart technologies, could transform the way we grow food, including avocados. The sustainability of avocado production in the face of climate change will depend on our collective ability to adapt, innovate, and support those most affected by these changes. The beloved avocado’s future hangs in the balance, underscoring the urgent need for action in the face of climate change.
