“…Still, literature related to land drainage is often difficult to retrieve and did not converge in the more recent studies on flood damage modelling, as much of the work is reported in grey literature (see e.g. Hallett et al, 2016).…”

Abstract. This paper presents AGRIDE-c, a conceptual model for the assessment of flood damage to crops, in favour of more comprehensive flood damage assessments. Available knowledge on damage mechanisms triggered by inundation phenomena is systematised in a usable and consistent tool, with the main strength represented by the integration of physical damage assessment into the evaluation of its economic consequences on the income of the farmers. This allows AGRIDE-c to be used to guide the flood damage assessment process in different geographical and economic contexts, as demonstrated by the example provided in this study for the Po Plain (north of Italy). The development and implementation of the model highlighted that a thorough understanding and modelling of mechanisms causing damage to crops is a powerful tool to support more effective damage mitigation strategies, both at public and at private (i.e. farmers) levels.

“…Initiation of habitat and floodplain restoration of the river system would need to take into consideration all of the system-level impacts that contributed to degradation of the system over time. These impacts included (1) leveed floodplains, (2) agriculture and urbanization, (3) increased flood flashiness, (4) increased river flows from diversion, (5) unnaturally high river water levels, (6) invasive species, and (7) high loads of sediment, contaminants, and nutrients (Jackson & Pringle, 2010;Guida et al, 2016;Sparks et al, 2016;Lemke et al 2017a). The story of the Emiquon Preserve began in 2000.…”

Introduction: The ecology of a river floodplain and the Emiquon preserve

Scientific study of the Illinois River began before a century of anthropogenic change, thus providing a unique perspective for describing river ecology restoration. In this issue, we explain how systematic monitoring revealed patterns in the restoration of the 2723-ha Emiquon Preserve on the Illinois River. The papers describe (1) how planktonic microorganisms, vegetation, fish, and waterbird communities responded rapidly to flooding of former shallow lakes and wetlands that had been drained and used for dryland agriculture for 83 years; (2) how variation of hydrologic conditions favors biotic community diversity and conditions for carbon sequestration; (3) how fish populations imposed a trophic cascade and affected diversity, yet may not help control some undesirable fish species; and (4) how simulation models are useful in planning, but that restoration practice and management decisions must adapt to present conditions, involve trade-offs, and are influenced by competing stakeholder interests. Unsurprisingly, water level management remains the most important factor in the restoration ecology of floodplains; however, the establishment of a river-floodplain connection should be managed to achieve a balance between establishing hydrology that mimics natural flood pulses while minimizing contemporary threats, including excessive nutrient and sediment loads and invasive species.

“…Atualmente, as várzeas encontram-se entre os ecossistemas mais impactados, sofrem contínuas modificações em sua estrutura e rupturas de suas conexões com os corpos hídricos em função das obras de engenharia, como represamentos ou vias de acesso (ZEDLER & KERCHER, 2005;GUIDA et al, 2016;WATSON et al, 2016). Não obstante, no Brasil esses sistemas encontram-se ameaçados, visto que a Lei de Proteção da Vegetação Nativa -LPVN (Lei Federal n° 12.651/12) não traz mecanismos para assegurar sua proteção e favorece o aumento da produção agrícola em áreas de vegetação nativa, que eram antes legalmente protegidas (MERTINELLI et al, 2010;JUNK & PIEDADE, 2015).…”

The wetlands are among the most threatened ecosystems, although in the Brazil that situation is worse because of an ecological approach lack in the Law of Native Vegetation Protection, what makes necessary the public power action to safeguard those systems. The present research employed an applied ecological approach (limnology, macroinvertebrates, aquatic macrophytes) for Sorocaba River and its wetlands assessment in Sorocaba-SP municipality, the land cover and its influence on limnological variables, as well as the environmental services demand supplied by the municipality wetlands. Two samples were performed during 2017, one during the rainy (February) season and other on the dry season (June). Patronized methods were employed in the present research. The organic pollution and the anthropic areas predominance are the mainly factors responsible for limnological variables alteration. Some environmental services (i.e. water provision, water flow control, erosive process control, nutrient control, water cycling, recreation fishing and biodiversity intrinsic value) provided by the studied wetlands showed a negative balance (i.e. demand superior to the provision capacity). The macrophyte species and macroinvertebrate families found are organic pollution indicators. Finally, stand out the strategic action contribution and the municipality governance role for wetlands ecosystem management.
