Abstract
Changing of agroclimatic indicators is one of the most problematic challenges of our time, affecting agroecosystems and biodiversity across the globe. Abiotic stress refers to the negative impact of non-living factors on living organisms in an ecosystem. Rhythms of change in agroclimatic indicators in recent years have been higher than expected. Abiotic stress brings changes in plant growth, development and metabolism, leading to reduced plant yields and changes in ecosystems. The study focused on the multi-year analysis of main climate indicators, such as temperature and precipitation. Collected data from hydrometeorological stations in the Korça region, Albania, were processed and compared with the corresponding indicators of data from the previous 30-year periods. Heat and drought are undoubtedly the two most important stresses that have a major impact on crop productivity. The average temperature and its extremes show an increasing trend from year to year. The annual amount of precipitation shows insignificant fluctuations, while the amount of precipitation that falls on fewer days but in larger daily amounts is a concern for plants. The structure of the diagram, where are integrated the temperature and average monthly precipitation, showed that there is an increase in the drought period. Changes in agroclimatic indicators present a challenge for producers in the field of agriculture, for the remodeling of agricultural areas and the determination of the most appropriate technologies for the cultivation of agricultural crops.
