Crop Yields Reduced By Climate Extremes

Mar 14, 2023

From 1980 to 2009, farmers faced an ever-increasing chance of having to deal with a growing season that was too hot and dry for their crops, according to a new study from an international team led by researchers at Aalto University. Wheat growers saw the biggest change, with the chance of extreme heat and drought during the growing season increasing sixfold over the study period. The risk for maize, rice, and soybean doubled – a smaller increase, but nevertheless considerable.

The researchers also investigated the effect of these conditions on crop yields. Their model showed that heat and drought reduced wheat yields by about 4% overall, though some regions saw much greater reductions, notably parts of Russia and China, both major global producers globally.

Video: Democratizing Gene Editing - Pairwise’s Vision for the Future of Agriculture

Pairwise has built its business around an idea that runs counter to how many companies approach innovation: make transformative technology easier to access.

In this Seed World interview, CEO Tom Adams discusses why broader access to gene editing could speed crop improvement, expand innovation opportunities and help agriculture address emerging challenges. He explains why Pairwise believes no single company can solve all of agriculture's problems alone—and why making advanced breeding technologies available to more organizations could accelerate progress across the industry.

The conversation explores how consumer trust influences technology adoption, why innovations like pitless cherries and seedless blackberries matter beyond convenience, and how future crop improvements could help address labor shortages, automation, harvest efficiency and other production challenges. Adams also shares his perspective on what the industry may be underestimating about the next wave of gene editing innovation.

Watch the full interview to hear why Pairwise believes agriculture is approaching an important inflection point for gene editing, and why the pace of innovation over the next decade could surprise the industry.

Topics Covered:

o Democratizing agricultural innovation

o Consumer trust and technology adoption

o The business case for sharing innovation

o Expanding innovation beyond major crops

o Next-generation breeding technologies
