RESEARCH GOALS

The major goal of the research in the City of Lodz is application of ecohydrology in Integrated Urban Water Management.Water in the urban space has been considered traditionally mostly from the perspective of water supply, sewage purification and storm water management. Recent years brought up awareness of the necessity of environmental conservation. However there has been still little holistic consideration of the potential of freshwater and terrestrial ecosystems as a tool for control of the hydrological cycle in city catchments.According to ecohydrology concept, urbanization should be seen as a process that by extinction of natural structures and their replacement with artificial ones, disrupts flow paths of energy, water and matter, within and between adjacent ecosystems, re-directing them into unsustainable, human originated tracks. Such transformations pose major ecological consequences for freshwaters which are the receivers of the deregulated, extreme runoff and accelerated flow of water and matter from disrupted natural cycles (Zalewski 2000). These changes not only directly affects water quality and quantity in degraded catchment, but also handicaps the resilience of freshwater ecosystems – their ability to maintain oscillations within the steady state. Consequently, ecosystems functions and ability to provide services may be permanently amended (Krauze & Wagner, 2007), affecting human health and wellbeing in cities (Kuprys-Lipinska et all, in press).Ecohydrology assumes, that due to the above processes, environmental degradation can not be compensated by application of only technological solutions, which do not address efficiently the effects of degradation of the elements of natural cycles in catchments (Zalewski & Wagner, 2005). Reduction of impacts in urban areas is the foremost and fundamental conditions, however should be supported by simultaneous procedures allowing: 1) increasing absorbing capacity of urban catchments for minimizing impact, and 2) reduction of the occurrence of degradation symptoms by augmenting assimilative capacity of freshwater ecosystems (Zalewski & Wagner, 2005). According to ecohydrology concept this can be achieved by using ecosystem properties as a management tool, e.g., in order to reduce hydro peaking, improve water quality and retention, convert excess nutrients, pollutants and sludge in to re-usable bioenergy (e.g., from biomass). Thus the need for cost-efficient, integrated solutions extending technical systems for urban water management with ecological measures, that may not only improve the quality of environment but also lower costs of management and rise economic income for society (Wagner- Lotkowska at al, 2004). Ecohydrology is a trans-disciplinary approach, using the understanding of relationships between hydrological and biological processes at the catchment scale to improve water quality, biodiversity and sustainable development (Zalewski 2006). The concept has been applied in variety of semi-natural and medium-disturbed catchments (e.g., Wagner-Lotkowska et al., 2005, Agostinho et al., 2005, Wolanski et al., 2006), while it’s testing in the city landscape which is addressed in his demonstration Project still reminds to be a challenge.
