Yikes! The knock on effects of climate change seem quite bad… The upside of this is that increasing agricultural productivity, and adaptation to a changing climate, can reduce deforestation pressures… Let’s slow climate change and increase agricultural productivity!

Anyone who has studied development economics has learned about the structural transformation of national economies that occurs amid the development process. The traditional narrative emphasizes intersectoral labour reallocation out of agriculture and into manufacturing and services.

In low-income countries, most people work in farming; in richer countries, they work in services
This graphic illustrates the distribution of the labor force across different sectors—agriculture, industry, and services—based on income levels of countries in 2023.

On the left, there is a stacked bar representing low-income countries, where 59% of the workforce is in agriculture, 10% in industry, and 31% in services. Next, the lower-middle-income group shows a breakdown of 40% in agriculture, 23% in industry, and 37% in services. The upper-middle-income countries have 21% in agriculture, 28% in industry, and 51% in services. Finally, in high-income countries, only 3% of the labor force is in agriculture, with 23% in industry and 74% in services.

The title highlights the trend that higher-income countries have fewer agricultural workers and a greater proportion involved in industry and services. The footer indicates the data source is the International Labor Organization (2025)
