“…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.

“…Forest cover contributes importantly to local atmospheric cooling through the energy exchange occurring with evaporation and transpiration (Fall et al, 2010;Hesslerova et al, 2012Hesslerova et al, , 2013. Evidence of warming associated with deforestation has been observed in numerous studies (Cook et al, 2010;Kravcík et al, 2007;Millán et al, 2005Millan M. M., 2007Costa and Pires, 2009).…”

Aspectos Físico-Químicos Da Água Do Ribeirão Das Abóboras Em Rio Verde (Go) E Impactos Na Qualidade Hídrica

O desenvolvimento de uma região depende de disponibilidade hídrica em quantidade e qualidade adequadas para atender sua demanda. Entretanto, as bacias hidrográficas vêm passando por transformações em sua paisagem em decorrência de ações antrópicas. Rio Verde (GO) é o principal município da microrregião Sudoeste de Goiás, com destaque na produção de soja, milho, aves e suínos, além de apresentar diversas empresas instaladas. Esse desenvolvimento econômico, sem planejamento ambiental adequado, tem causado danos às fontes de água. Nesse contexto, o objetivo deste estudo foi analisar aspectos físico-químicos da água do ribeirão das Abóboras, principal fonte fornecedora de água para a população urbana rio-verdense e de outros usos no município. Foram analisadas as variáveis temperatura, pH, oxigênio dissolvido, condutividade elétrica, sólidos totais dissolvidos, turbidez, demanda bioquímica de oxigênio, nitrato e fósforo total. Resultados da demanda bioquímica de oxigênio e de fósforo total não atenderam aos limites estabelecido pela Resolução CONAMA 357/05 para água doce classe 2. Níveis de condutividade elétrica inferem que a água está impactada. Este trabalho pode subsidiar o planejamento e a gestão das bacias hidrográficas do município e de outras regiões, melhorando a qualidade ambiental.
