The Standardized Precipitation Evapotranspiration Index (SPEI) analysis was conducted using monthly precipitation data and temperature data on a 12.5 km × 12.5 km resolution based on a Representative Concentration Pathways (RCP) 8.5 climate change scenario, and the characteristics of drought were identified by the threshold. In addition, the changes in drought severity and intensity were projected using the threshold based on the run-length concept and frequency analysis. As a result of the analysis, the probability density function of the total drought and maximum drought intensity moved the upper tail for the upcoming years, and the average drought intensity was also projected to become stronger in the future than in the present to the right side. Through this, it could be projected that the drought scale and frequency and the drought intensity will become severer over South Korea because of future climate change.

The problem of climate change and global warming both in whole and in particular has become one of the most serious and urgent directions of scientific and technical activity at the present stage. The future food security of Ukraine depends on the effectiveness of adaptation of agriculture to new conditions dictated by the global anthropogenic warming. In order to evaluate possible impact of climate change in Ukraine on agroclimatic indicators the scenario A1B - "moderate" was used providing a balance between all energy sources. Researches of sunflower harvest formation are carried out using a dynamic model of agricultural crops productivity. For a comparative analysis of scenary meteorological variables with previous data the period from 1986 to 2005 is taken from agroclimatic directory of Ukraine. It serves as a base when performing calculations. According to calculations of A1B climate change scenario, periods of sowing and subsequent phases of development will occur earlier than at present, which will lead to reduction of the whole vegetation period at most parts of the area under study. As a result of comparative analysis of temperature and precipitation regime it was found that, subject to implementation of the climate change scenario under study, expected weather conditions will be more favourable for cultivation of sun-flower in the Western and Central forest-steppe, as well as at the Right-Bank Ukraine and in the Donetsk sub-zone of Northern steppe of Ukraine.

In recent years, agroforestry has gained increasing attention as an option to simultaneously alleviate poverty, provide ecological benefits, and mitigate climate change. The present study simulates small-scale farmers’ agroforestry adoption decisions to investigate the consequences for livelihoods and the environment over time. To explore the interdependencies between agroforestry adoption, livelihoods, and the environment, an agent-based model adjusted to a case study area in rural Indonesia was implemented. Thereby, the model compares different scenarios, including a climate change scenario. The agroforestry system under investigation consists of an illipe (Shorea stenoptera) rubber (Hevea brasiliensis) mix, which are both locally valued tree species. The simulations reveal that farmers who adopt agroforestry diversify their livelihood portfolio while increasing income. Additionally, the model predicts environmental benefits: enhanced biodiversity and higher carbon sequestration in the landscape. The benefits of agroforestry for livelihoods and nature gain particular importance in the climate change scenario. The results therefore provide policy-makers and practitioners with insights into the dynamic economic and environmental advantages of promoting agroforestry.
