“…Energy is transformed into latent heat, which cools down the landscape. These relations have been described and are supported by research and data measurements in the following studies (Monteith 1981;Kedziora 1987, 2007;Ripl 2003Ripl , 2010Hesslerová et al 2012Hesslerová et al , 2013Pokorný et al 2010;Eiseltová et al 2012;Brom et al 2012;Procházka et al 2009;Huryna and Pokorný 2010;Makarieva et al 2013).…”

The aim of this study is to demonstrate and emphasize the importance of wetlands and permanent vegetation in an agriculture landscape. We compared functional aspects (surface temperature, wetness, and vegetation) of seven different cadastres (administrative units) in two distinctive regions in the Czech Republic. In terms of land cover, one is represented by heterogeneous mosaic, the other by intensive agriculture. Functional aspects were calculated for each cadastre and then within the region compared among themselves. The comparison was realized during the growing season, i.e., in the months of May to September.The study, based on Landsat satellite data assessment, confirmed that areas with a higher proportion of forest and wetlands can provide a more balanced temperature-moisture regime of the landscape throughout the growing season, low temperatures, and high humidity. In these areas, the solar radiation is transformed into latent heat which leads to landscape cooling, minimizing erosion, and loss of water, matter, and nutrients. In the landscape where crops dominate, temperature-moisture regime is characterized by high temperature and its amplitude and low humidity. The exception is the beginning of the growing season when the landscape is cooled by intensive crop growth. In periods of high stage of maturity or after harvest, the agricultural landscape is characterized by high surface temperature. At the end of this chapter, we present suggestions for sustainable management of agricultural landscape, which is represented by construction of wetlands.

“…Accordingly, vegetation that is well supplied with water can effectively reduce temperature gradient occurring between adjacent areas. The differences between vegetation well supplied with water and drained areas can reach up to 20 C (Hesslerova et al 2013). The diurnal mean evapotranspiration was up to 1.3 mm, 1.7 mm, 3.4 mm and 1.1 mm higher at the wet meadow in comparison with barley field, wheat, cornfield and rapeseed, respectively, for days with high intensity of solar radiation.…”

“…(Milly 1997;Adegoke and Carleton 2000;Eckhardt and Ulbrich 2003). Land-use practices such as deforestation, agriculture, and grazing may impact on a local hydrological cycle and climate (Bryant et al 1990;Pielke et al 1991;Vitousek 1994;Pielke et al 1998;Hesslerova et al 2013). Recent studies have showed that extensive deforestation has decreased evapotranspiration (Henderson-Sellers et al 1993;Werth and Avissar 2002;Sanches et al 2011;Ma et al 2013).…”

This study examines the impact of plant cover on water and energy exchange between land and atmosphere in the Třeboň Biosphere Reserve, Czech Republic. Energy fluxes, evapotranspiration and evaporative fraction were determined over typical crops of agriculture landscape and compared with fluxes in an adjacent wet meadow. The results show distinct differences in heat and water exchange between these ecosystems. Diurnal average difference in evapotranspiration rates for days with high irradiance over the wet meadow and arable crops ranged from 1.1 mm day À1 to 3.4 mm day À1 . Furthermore, the evapotranspiration differences between C3 (rapeseed) and C4 (cornfield) was about 2.3 mm day À1 . Analysis of thermovision pictures showed that temperature variation reached about 9 C between the ploughed field and meadows at the time of maximum intensity of solar radiation. Heat exchange (sensible heat flux) was greater over arable lands, while water exchange (latent heat flux) was stronger over the wet meadow. The evaporative fraction displayed that more than 100 % of available energy was released by the wet meadow through evapotranspiration due to the advection of dry air from the surroundings. Wetlands show equal or even inverse temperature in vertical profile, whereas corn and wheat show noticeable higher temperature at soil surface in comparison with plant stand surface. Therefore, we suggest that introduction of wetlands to agricultural land is one of the most important instruments for the management of water and heat balance of the landscape.

“…This fact imply that impact of regional warming in the Lisnyky forest has been mitigated probably due to the water body cooling effect coupled with canopy shading and evapotranspiration (Hesslerová et al, 2013;Elisson et al, 2017). Micro-and mezoclimate investigations in riparian ecosystems suggest that soil moisture, air humidity, air and soil temperature are different from those in surrounding territory (Brosofske et al, 1997;Danehy & Kirpes, 2000;Agafonov & Gurskaya, 2013;Capon et al, 2013;Hadaš, 2003).…”

Climate change has a significant impact on natural ecosystems, particularly on floodplain forests that are among the most transformed ecosystems in the world. The climate sensitivity of dominant species is likely to play a key role in determining the susceptibility of flooded forests to climate changes. Here, we use dendrochronological approaches and local climate records from 1880 to 2015 to assess the response in pedunculate oak (Quercus robur L.) trees growing in a floodplain of the Dnipro River near Kyiv to climatic variables. Correlation analysis reveals the strongest positive association of the Q. robur tree-ring width chronology with May-June precipitation, May-June temperature, and May self-calibrating Palmers drought severity indices (scPDSI). The moving-window correlation analysis points to positive association with the scPDSI after the 1950s, when local river regulation was implemented. The positive correlation with current March precipitation is the least expected change in the oak growth-to-climate relationship that occurred in the aftermath of human alterations in the local river and regional climate changes. This study discusses the probable ecological consequences and ecophysiological mechanisms of observable climate-to-growth relationships and their temporal stability.
