According to the Intergovernmental Panel on Global Change (IPCC), global air-temperature has risen by more than 0.7 oC over the last 100 years, with East Asia, particularly Japan exhibiting an increase of nearly 1 oC. A recent survey revealed that this temperature increase has already adversely affected crop growth in various respects, and are particularly noticeable in horticultural crops such as fruit trees, vegetables, and flowers. The phenological changes of horticultural crops caused by increased temperature can be frequently observed in fruit-size enlargement, softening of fruit flesh, increased acidity, skin/leaf burning, insufficient color development and fruit deformity, decreased fruit setting, lack of head formation in heading c rucifers, increased physiological disorders such as tip-burn and blossom end-rot, delay of endodormancy, etc.
To mitigate the adverse effects of climate change on the production and quality of horticultural produce, strategic and technological countermeasures should be developed, as well as adaptation technologies against increased temperature and other climatic abnormalities. In addition, a more reliable and accurate impact assessment of climate change in its nature, degree of severit y, duration and pattern on agriculture must be established.
The international seminar on “Risk Mitigation of Climate Change for the Sustainable Production of High Quality Crops in Asia” was organized by FFTC and its partner, the NARO Institute of Fruit Tree Sciences (NIFTS) of Japan and the Council of Agriculture (COA), Taiwan, ROC. The objectives of the international seminar was to obtain a better understanding of the adverse effects of climate changes on the production and quality of horticultural produce and its strategic and technological countermeasures to mitigate its effects; and to establish a more reliable and accurate impact assessment of climate change in its nature, degree of severity, duration and pattern on agriculture.
