Resumo(s)
Crop sustainability can be threatened by new environmental challenges regarding
predicted climate changes and global warming. Therefore, the study of real biological
impacts of future environmental conditions (e.g., increased air [CO2], supra-optimal
temperature and water scarcity) on crop plants, as well as the re-evaluation of management
procedures and strategies, must be undertaken in order to improve crop adaptation
and promote mitigation of negative environmental impacts, thus affording crop
resilience. Coffee is a tropical crop that is grown in more than 80 countries, making it one
of the world’s most traded agricultural products, while involving millions of people
worldwide in the whole chain of value. It has been argued that this crop will be highly
affected by climate changes, resulting in decreases in both suitable areas for cultivation
and productivity, as well as impaired beverage quality in the near future. Here, we report
recent findings regarding coffee species exposure to combined supra-optimal air temperatures
and enhanced air [CO2], and impacts of drought stress on the crop. Ultimately, we
discuss key strategies to improve coffee performance in the context of new environmental
scenarios. The recent findings clearly show that high [CO2] has a positive impact on coffee
plants, increasing their tolerance to high temperatures. This has been related to a better plant vigor, to the triggering of protective mechanisms, and to a higher functional status of
the photosynthetic machinery. Even so, coffee plant is expected to suffer from water
scarcity in a changing world. Therefore, discussion is focused on some important management
strategies (e.g., shade systems, crop management and soil covering and terracing),
which can be implemented to improve coffee performance and sustain coffee production
in a continually changing environment
