FFTC Consultant Dr. George Kuo joins the discussion about the worldwide adverse effects of climate change as UPLB Chancellor Dr. Rex Victor Cruz, PCAARD's Executive Director Dr. Patricio Faylon and Director Rodolfo Ilao listen
Crop yield decrease of 3 to 10% may occur in the 2020s and 5 to 30% in the 2050s mostly in upland production areas in Asia according to reports from Intergovernmental Panel on Climate Change. Yield reduction is partly due to limited water resources, intense soil erosion, and evolvement of new pests due to changing climatic conditions.
Sloping lands, a fragile environment, has more than 1.5 billion inhabitants from the Southern hemisphere including Asia, says a United Nations Environment Report. Many countries in Asia have sloping to upland landscapes prone to adverse effects of climate change. South China, for example, has 90% of its subtropical regions in mountainous or hilly areas. Thailand has 35% of its total land area classified as uplands. The Philippines uplands comprise 31% and Vietnam has more than 70%.
Unfortunately, almost 50% of these upland agro ecosystems are degraded because of rapid depletion of forest cover, slash and burn practice of some farmers, migration of people in the uplands, and other man-made reasons. These anthropogenic causes when coupled with natural calamities further worsen land degradation.
In response to these concerns, participant-experts of the International Workshop on Sustainable Farming Strategies for Increased Resiliency of Sloping Land Agro Ecosystem Amid Climate Change presented and discussed some strategies and measures.
