    A wide range of climatic conditions in Ukraine causes significant regional differences in the vulnerability of forests to climate change. The mitigation/adaptation strategy should be based on assessments of their vulnerability at the regional level. Phytoindication model by prof. Y.P. Didukh (1994) was used to assess forest vulnerability. The model gives a quantitative estimation of climate as one of major environmental factors affecting the distribution, condition and productivity of vegetation on the base of climate-related indicators – continentality, humidity and frost. For these indicators climate suitability scales were calculated. Modeling was carried out for main forest species: Pinus sylvestris L., Quercus robur L., Fagus sylvatica L., Picea abies (L.) H.Karst, Betula pendula Roth., Alnus glutinosa (L.) Gaertn. and Robinia pseudoacacia L. Climate projections based on the Euro CORDEX time series (up to 2100) and 2 scenarios of the Representative Concentration Pathways (RCP 4.5, RCP 8.5) were used. By means of Q-GIS the maps containing zones of suitability to climate for each of studied species were created for current climate conditions and future time series. The directions for strengthening the mitigation and adaptive capacity of forests are considered. The mainstream for nature-based solutions is adaptive sustainable forest management, which provides: 1)optimization of land use structure and increasing the forested area; 2) development and implementation of a national forestry program considering the priorities of climate change and low-carbon development; 3) using wood to substitute greenhouse gas intensive-materials and fossil fuels; 4) best forestry practices through the introduction of modern Climate Smart Forestry principles.

    The land-use change in the Hasdeo River watershed has been observed with all its subwatersheds. The changing patterns may portend localized impairment to forest and agricultural watershed. In this study, Land-use land-cover (LULC) change was modeled using terrset modeling software. The Hasdeo river watershed (geographical extent of 10,396.373 km2) is a part of the Mahanadi River basin in Chhattisgarh, India. Hasdeo River originates from Sonhat (Koriya district, Chhattisgarh, India) and is submerged into the river Mahanadi. It flows in the stretch of 330 km from north to south direction. This river has eight subwatersheds with rich forest diversity and perennial water resources. IRS-1D & P6 LISS3 images from the years 2000 and 2013 were used to investigate the LULC pattern. This has been used for the prediction of LULC change patterns for the years 2035 and 2050 based on the Markov model. The result of the project LULC map for the year 2000-2035 and 2000-2050 shows that the dense forest area will decrease by 12.30% and 15.68% respectively. The settlement area will significantly increase by 20.13% (2035) and 34.90% (2050) and will be the dominant land-use type in the watershed. It shows that population pressure will directly affect forest vegetation and agriculture activities. This study will be helpful for the effective sustainability approach for maintaining the proper LULC pattern of LULC pattern of land-use change in the watershed. This changing pattern will also influence the farming pattern in the catchment area of the Hasdeo River watershed.

    Preserving biodiversity in a warming climate: adapting strategies in forestry and nature conservation

    It is a challenge for today’s conservation managers to adapt their strategies to a changing climate. We systematically compiled recommendations from scientific literature reviews regarding adapting biodiversity conservation to climate change in boreal and temperate regions. Both direct (changed temperature, precipitation, sea level) and indirect effects (such as increased natural disturbances and changed land use) of climate change were considered. Most recommendations belonged to eight dominating categories: (i) Promote both connectivity that facilitates dispersal through the landscape and connectivity that maintains populations within the landscapes; (ii) Focus on certain types of sites, especially those that can act as climate refugia, since they have heterogeneous climatic conditions; (iii) Protect a few large areas rather than many smaller, since then species can to a higher extent persist within the protected areas at climate change; (iv) Consider the regional location, especially by locating conservation measures at sites predicted to become important for biodiversity in the future, such as sites located at higher elevations and closer to the poles; (v) protect areas also temporarily, as a response to extreme events or changes in range distributions; (vi) increase habitat diversity over landscapes by protecting many different habitats; (vii) mitigate habitat deterioration caused by climate change and restore degraded habitats in production landscapes, and (viii) decrease the intensity and adapt practices in forestry to climate change, for example by increasing the ecological resilience to climatic stresses.
    Climate change implies that more conservation efforts are required to reach conservation goals. To protect forest biodiversity in the future, both traditional conservation strategies and strategies adapted to climate change are needed; in addition, novel approaches developed as a response to climate change will become increasingly relevant.
