Coffee, wine and chocolate? Climate change coming for popular foods – Key Biscayne Portal

Report on Climate Change Impacts on Key Agricultural Commodities and the Efficacy of Climate Intervention

Introduction: Threats to Sustainable Development

A recent study highlights the severe threat posed by global warming to the global supply of coffee, wine, and chocolate. The cultivation of grape, coffee, and cacao crops is increasingly vulnerable to the effects of climate change, directly impacting several Sustainable Development Goals (SDGs). These crops are vital to many economies and provide livelihoods for millions of farmers worldwide, making their stability crucial for achieving SDG 1 (No Poverty) and SDG 8 (Decent Work and Economic Growth). Fluctuations in crop yields caused by rising temperatures and altered rainfall patterns jeopardize the economic security of these communities and disrupt progress toward SDG 2 (Zero Hunger) by affecting the income used to ensure food security.

Analysis of Climate Change Impacts on Global Agriculture

Threats to Livelihoods and Economic Stability (SDG 1 & SDG 8)

The primary challenge identified is the increasing volatility in agricultural production, which undermines the stability required for sustainable economic growth and poverty reduction. Key impacts include:

• Increased vulnerability for grape, coffee, and cacao crops, which are cornerstones of many national and local economies.
• Significant variations in crop yields from year to year, preventing farmers from relying on stable harvests and predictable income.
• Direct risks to the livelihoods of farming communities who depend on these crops for their economic survival.

Evaluation of Stratospheric Aerosol Injection (SAI) as a Climate Action (SDG 13)

The study investigated the potential of Stratospheric Aerosol Injection (SAI), a hypothetical geoengineering technique, to mitigate climate change impacts on agriculture. The research aimed to determine if SAI could stabilize growing conditions in line with SDG 13 (Climate Action).

Research Methodology

The assessment of SAI’s effectiveness was conducted through a systematic process:

1. Climate simulations were run to model the effects of SAI on 18 key crop-growing regions across western Europe, South America, and West Africa.
2. The study focused on the period between 2036 and 2045.
3. Crop suitability was assessed based on critical factors including temperature, rainfall, humidity, and disease risk.
4. The results from SAI scenarios were compared against a future scenario without climate intervention.

Key Findings and Limitations

While SAI demonstrated some potential, its overall effectiveness was found to be limited and unreliable for securing agricultural stability.

• SAI was effective in reducing surface temperatures across the studied regions.
• However, it failed to consistently preserve the comprehensive conditions required for successful crop cultivation.
• Only six out of the 18 regions (one-third) showed reliable improvement in growing conditions under the SAI scenarios.
• The primary limitation was SAI’s inability to manage unpredictable rainfall and humidity, which undermined the benefits of temperature reduction.
• This inconsistency in managing hydrological cycles leads to continued unpredictability in crop yields and revenue, failing to provide a stable solution for farmers.

Conclusion and Recommendations for Achieving Sustainable Development Goals

The Insufficiency of Singular Technological Interventions

The research concludes that technological interventions focusing solely on temperature reduction are insufficient. For example, cacao is highly susceptible to pests and diseases exacerbated by a combination of high temperature, rainfall, and humidity. Even with cooler temperatures from SAI, the unmanaged hydrological factors would continue to threaten the crop. This underscores that isolated climate interventions cannot fully address the complex challenges facing agriculture.

A Call for Integrated Global Action (SDG 17)

Achieving long-term agricultural sustainability requires a multifaceted approach grounded in global partnership, as outlined in SDG 17 (Partnerships for the Goals). The study’s findings lead to the following recommendations:

• Recognize that climate interventions like SAI are not a guaranteed solution for the challenges facing specialized crop farming.
• Develop and implement adaptation strategies tailored to local environmental and social conditions, a key target of SDG 13.
• Increase investment in resilient agricultural practices that can withstand climate variability, directly supporting the aims of SDG 2.
• Foster global cooperation to ensure the protection of these vital crops and the communities that depend on them for their livelihoods.

Analysis of Sustainable Development Goals in the Article

1. Which SDGs are addressed or connected to the issues highlighted in the article?

The article highlights issues that are directly connected to several Sustainable Development Goals (SDGs). The primary themes of climate change, its impact on agriculture, and the subsequent economic consequences for farmers and economies link to the following SDGs:

1. SDG 13: Climate Action
   • The core issue discussed is “global warming” and “rising global temperatures” threatening specific crops. The article explicitly examines the effects of climate change and a potential climate intervention strategy (Stratospheric Aerosol Injection – SAI), which places it squarely within the scope of SDG 13.
2. SDG 2: Zero Hunger
   • While the crops mentioned (coffee, wine, chocolate) are not staple foods, the article focuses on agricultural stability and food production systems. It warns that climate change causes “big variations in crop yields from year to year,” threatening the stability of harvests. This directly relates to the goal of ensuring sustainable food production and resilient agricultural practices.
3. SDG 8: Decent Work and Economic Growth
   • The article states that the affected crops are “vital to many economies and provide livelihoods for farmers worldwide.” The threat to these crops is a direct threat to the economic stability and employment of communities that depend on them, linking the issue to sustainable economic growth and decent work.

2. What specific targets under those SDGs can be identified based on the article’s content?

Based on the article’s discussion of climate impacts on agriculture and livelihoods, the following specific SDG targets can be identified:

1. Under SDG 13 (Climate Action):
   • Target 13.1: Strengthen resilience and adaptive capacity to climate-related hazards and natural disasters in all countries. The article discusses how crops are “increasingly vulnerable to the effects of climate change,” such as “rising temperatures and changing patterns of rainfall.” It also highlights the need for “adaptation strategies tailored to local conditions” to cope with these hazards.
2. Under SDG 2 (Zero Hunger):
   • Target 2.4: By 2030, ensure sustainable food production systems and implement resilient agricultural practices that increase productivity and production… and strengthen capacity for adaptation to climate change, extreme weather, drought, flooding and other disasters. The article’s central theme is the threat to the “successful cultivation of the crops” due to climate change. It implicitly calls for “resilient agricultural practices” by noting that current systems are failing to provide a “stability of their harvest.”
3. Under SDG 8 (Decent Work and Economic Growth):
   • Target 8.2: Achieve higher levels of economic productivity through diversification, technological upgrading and innovation… The article discusses how climate change threatens the productivity of high-value crops that are “vital to many economies.” The instability of harvests and “projected revenue” directly impacts the economic productivity of these agricultural sectors.

3. Are there any indicators mentioned or implied in the article that can be used to measure progress towards the identified targets?

The article does not explicitly mention official SDG indicators, but it implies several metrics that can be used to measure the problems and any progress towards the targets:

• Climatic Condition Indicators: The study assesses crop suitability based on measurable factors like “temperature,” “rainfall,” and “humidity.” The article mentions that Stratospheric Aerosol Injection (SAI) “did reduce surface temperatures” but failed to manage “unpredictable rainfall and humidity.” These factors serve as direct indicators of changing climate conditions affecting agriculture.
• Agricultural Productivity Indicators: The article repeatedly refers to “crop yields” and the “stability of their harvest.” The “big variations in crop yields from year to year” is presented as a primary negative outcome of climate change. Therefore, measuring the annual yield and its stability would be a key performance indicator for Target 2.4.
• Economic Viability Indicators: The article mentions that inconsistent crop yields lead to unstable “projected revenue” and affect the “livelihoods of farmers.” Tracking the income of farmers and the revenue generated by these crops would be an indicator of progress towards Target 8.2.
• Pest and Disease Risk Indicators: The article notes that cacao is “highly susceptible to pests and diseases caused by a combination of high temperatures, rainfall, and humidity.” The incidence of crop disease could therefore be used as an indicator of agricultural resilience.
