How Climate Change Is Affecting Pea and Chickpea Harvests: What It Means for Your Favorite Snacks

Peas and chickpeas have become the darlings of the healthy snacking world. From crunchy roasted chickpeas to lightly salted pea snacks, these legumes are celebrated for their protein, fiber, and versatility. But behind every bag of your favorite snack lies a delicate agricultural process that is increasingly threatened by climate change.

As global temperatures rise and weather patterns become more unpredictable, farmers who grow peas and chickpeas are facing unprecedented challenges. In this article, we explore how climate change is affecting pea and chickpea harvests, the implications for the food supply chain, and what snack enthusiasts should know about the future of their go-to treats.

The Vulnerability of Legume Crops to Climate Shifts

Peas and chickpeas are cool-season legumes that thrive in moderate temperatures and consistent rainfall. Unlike hardier grains such as wheat or corn, these crops are highly sensitive to heat stress and water extremes. When temperatures exceed 30°C during flowering or pod filling, yields can drop dramatically—sometimes by 20 to 40 percent.

In major producing regions like Canada, India, and the U.S. Pacific Northwest, farmers have reported earlier springs and hotter summers that compress the growing window. Chickpeas, in particular, are vulnerable to drought because they have shallow root systems. Meanwhile, peas can suffer from excessive rain that leads to fungal diseases and lodging, where plants fall over and rot before harvest.

• Optimal growing temperature for peas: 13–21°C; for chickpeas: 15–25°C
• Heat waves during flowering can cause flower abortion and reduce pod set
• Erratic rainfall patterns increase the risk of both drought and waterlogging

Regional Impacts: From the Prairies to the Punjab

Canada is the world’s largest exporter of peas and a top producer of chickpeas. In recent years, the Canadian prairies have experienced severe droughts that cut pea yields by nearly 30% in some areas. Farmers have been forced to rotate away from legumes or invest in expensive irrigation systems.

In India, the world’s largest producer of chickpeas, monsoon variability is a growing concern. Delayed or insufficient rains during the sowing season can delay planting, while unseasonal heavy rains at harvest time damage mature pods. These disruptions not only reduce crop volume but also affect the quality—shriveled, discolored chickpeas are less desirable for snack manufacturers and fetch lower prices.

Australia, another key producer, has seen its chickpea acreage shrink as farmers switch to more drought-tolerant crops like sorghum or cotton. The combination of heat, water scarcity, and rising input costs is making legume farming riskier than ever.

• Canada: drought reduced pea yields by up to 30% in some regions
• India: monsoon variability threatens chickpea quality and quantity
• Australia: chickpea acreage declining due to water scarcity

How Climate Change Affects Snack Production and Prices

When harvests are disrupted, the ripple effects travel all the way to your snack shelf. Lower yields mean higher raw material costs, which can translate into higher retail prices for products like roasted chickpeas or crunchy pea snacks. Manufacturers may also face inconsistent supply, making it harder to maintain flavor profiles and product availability.

For snack brands that rely on consistent quality—such as those producing seasoned varieties like sea salt or barbecue—fluctuations in pea or chickpea size and color can complicate production. Smaller or misshapen legumes may not roast evenly, affecting the final crunch and taste. To mitigate these issues, some companies are investing in longer-term contracts with farmers, supporting sustainable farming practices, or exploring alternative legume sources.

• Supply shortages can lead to price increases for pea- and chickpea-based snacks
• Inconsistent raw material quality affects roasting and seasoning processes
• Brands are increasingly sourcing from multiple regions to hedge against climate risks

Adaptation Strategies: What Farmers and the Industry Are Doing

To safeguard future harvests, agricultural scientists are developing heat-tolerant and drought-resistant pea and chickpea varieties. Breeding programs in Canada, India, and Australia are selecting for traits like deeper root systems, earlier maturity, and better heat tolerance during flowering. These improved cultivars could help maintain yields even under warmer conditions.

On-farm practices are also evolving. Conservation tillage, cover cropping, and precision irrigation help retain soil moisture and reduce heat stress. Some farmers are shifting planting dates to avoid peak summer heat, while others are using shade nets or intercropping with taller plants to protect legumes from direct sun exposure.

For snack manufacturers, diversifying supply chains is key. By sourcing from different geographic regions and investing in long-term partnerships, companies can buffer against local crop failures. Some are also exploring indoor or controlled-environment agriculture for high-value legume ingredients, though this remains costly for large-scale production.

• Breeding heat-tolerant legume varieties is a top research priority
• Conservation tillage and precision irrigation reduce climate vulnerability
• Supply chain diversification helps snack brands maintain consistent product availability

What This Means for Snack Lovers

As a consumer, you might notice subtle changes in your favorite snacks—perhaps a slightly different texture, a variation in flavor intensity, or a higher price tag. But the good news is that the snack industry is resilient and innovative. Many brands are already taking steps to ensure that products like Crunchy Peas and Chickpeas Variety Pack remain available and delicious.

By supporting companies that prioritize sustainable sourcing and climate adaptation, you can help drive positive change. Look for brands that are transparent about their supply chains and invest in regenerative agriculture. And remember, choosing plant-based snacks like peas and chickpeas is already a more environmentally friendly choice compared to many animal-based or highly processed alternatives.

• Expect potential price increases or occasional flavor variations
• Support brands that invest in sustainable and climate-resilient sourcing
• Plant-based snacks like peas and chickpeas have a lower carbon footprint than many alternatives

Climate change is reshaping agriculture, and pea and chickpea harvests are on the front line. While challenges abound, the combination of scientific innovation, farmer adaptation, and industry commitment means your favorite crunchy snacks are likely here to stay—though they may evolve. To explore a range of delicious, responsibly sourced options, check out the Chickpeas Variety Pack and discover how you can enjoy great taste while supporting a more sustainable food system.
