FACING CLIMATE CHANGE EFFECTS ON POTATO CULTIVATION Presentation 2012
The research on climate changes effect on vegetable production was published in 2018
11 June 2018 Predicted environmental changes could significantly reduce global production of vegetables

IPCC 2007 4th assessment In terms of experimentation, there is still a lack of knowledge of CO2 and climate responses for many crops other than cereals, including many of importance to the rural poor, such as root crops, millet, brassica, etc., with few exceptions, e.g., peanut (Varaprasad et al., 2003) and coconut (Dash et al., 2002). IPCC 2007'
2014 IPCC 5th assessment did not give impacts information in general on cultivars (vegetables), including potatoes.
Cassava was included in the assessment. Cassava (also known as manioc) is an important source of food for many people in Africa and Latin America and recent
studies suggest that future climate should benefit its productivity as this crop is characterized by elevated optimum temperature for photosynthesis and growth, and a positive response to CO2 increases'. However this may come with a cost nutritional content (specific research needed). The increased production of cyanide by cassava with climate change is a problem
Fruit and nuts (IPCC 2014)
For perennial crops, winter chill accumulation that is important to many fruit and nut trees is projected to continue its decline, with, for instance, a 40 chill-hours per decade reduction projected for California for the
period up to 2100. Averaging over three GCMs, annual winter chill loss by 2050 compared to 1970 would
amount 17.7% to 22.6% in Egypt . Several studies have projected negative yield impacts of climate trends for perennial
trees, including apples in eastern Washington and cherries in California
Wine (IPCC 2014)
Reductions in suitability for grapevine are expected in most of the wine-producing regions
Potatoes2017, Rubí Raymundo, Climate change impact on global potato production,
Research projected a slight decline in potato yields by 2050 and significant decline by 2100.
Bananas are projected to withstand climate change with a proviso on pests.
