The impact of climate change and investment on fruit crop development

Abstract
An integrated approach is proposed to link the results of climate change impacts on average yields and economic development of orchard production. Based on the available data on the characteristics of the Southeastern region of Bulgaria and the main fruit crops grown there, a methodology for predicting average yields of apples, pears, apricots and zarzali, peaches and nectarines, and plums and zucchini is developed and validated, taking into account climate change. On the basis of the empirical relationships obtained between the average yields of these crops and the climatic factors on which they depend, the expected yields up to 2050 are predicted, as well as the areas required for each crop. Opportunities for fruit crop production are identified. The scale of production and the investment needed for it have been determined and their efficiency examined.
