Impact of climate change on pepper cultivation - A global suitability analysis

Black pepper plays a central role in the culinary traditions of many countries and in the global economy. But how will climate change affect the cultivation of this important spice? This question was the focus of the research project, which for the first time examined the global cultivation areas of pepper under current and future climatic conditions.

Shifting of suitable cultivation areas possible

‍

The research team created a comprehensive model to illustrate the global suitability of pepper for cultivation. Climatic, topographical and soil-related factors were taken into account, as well as various socio-economic developments.

The results show that the current pepper cultivation areas could experience both positive and negative changes in the future. While higher temperatures could even be beneficial in some regions, changing precipitation patterns and longer periods of drought could make cultivation considerably more difficult. The availability of water in particular will therefore be a decisive factor for successful pepper cultivation in the future.

This study is an important first step in understanding the future suitability of pepper for cultivation and developing possible adaptation strategies. It also provides a valuable tool to assess the impact of climate change on other important spices and herbs.
