Building bridges between environmental and political agendas is essential nowadays in face of the increasing human pressure on natural environments, including wetlands. Wetlands provide critical ecosystem services for humanity and can generate a considerable direct or indirect income to the local communities. To meet many of the sustainable development goals, we need to move our trajectory from the current environmental destructive development to a wiser wetland use. The current article contain a proposed agenda for the Pantanal aiming the improvement of public policy for conservation in the Pantanal, one of the largest, most diverse, and continuous inland wetland in the world. We suggest and discuss a list of 11 essential interfaces between science, policy, and development in region linked to the proposed agenda. We believe that a functional science network can booster the collaborative capability to generate creative ideas and solutions to address the big challenges faced by the Pantanal wetland.

Wetlands are often vital physical and social components of a country’s natural capital, as well as providers of ecosystem services to local and national communities. We performed a network analysis to prioritize Sustainable Development Goal (SDG) targets for sustainable development in iconic wetlands and wetlandscapes around the world. The analysis was based on the information and perceptions on 45 wetlandscapes worldwide by 49 wetland researchers of the Global Wetland Ecohydrological Network (GWEN). We identified three 2030 Agenda targets of high priority across the wetlandscapes needed to achieve sustainable development: Target 6.3—“Improve water quality”; 2.4—“Sustainable food production”; and 12.2—“Sustainable management of resources”. Moreover, we found specific feedback mechanisms and synergies between SDG targets in the context of wetlands. The most consistent reinforcing interactions were the influence of Target 12.2 on 8.4—“Efficient resource consumption”; and that of Target 6.3 on 12.2. The wetlandscapes could be differentiated in four bundles of distinctive priority SDG-targets: “Basic human needs”, “Sustainable tourism”, “Environmental impact in urban wetlands”, and “Improving and conserving environment”. In general, we find that the SDG groups, targets, and interactions stress that maintaining good water quality and a “wise use” of wetlandscapes are vital to attaining sustainable development within these sensitive ecosystems.

The spatial and temporal variability of water levels was investigated across a section of floodplain in the Pantanal that represents typical geomorphic and ecological complexity of these environments. A series of 11 staff gauges were installed along a 12-km transect running perpendicularly from the Cuiabá River into the floodplain. The staff gauges were monitored fortnightly during the flood seasons from 2004 to 2007. Contrary to what is often assumed, the water surface profile was never level, and it was particularly variable when there was less water on the floodplain. Water surface slope varied from 1.4 9 10 -4 (unitless) to 1.3 9 10 -3 indicating substantial water movement that was verified by flow observations. The spatial patterns of water level variation were repeated across years, even though there was considerable interannual variation in magnitude and duration of floodplain inundation. In 2004 and 2005, the duration of inundation was 121 and 120 days, respectively, but in 2006 and 2007, inundation lasted 166 and 157 days, respectively. These observations reveal considerable small-scale spatial variability in the water surface profile, but with persistent patterns over space and time that are related to the river hydrograph and the channels that convey flood waters across the area. This study contributes to our understanding of inundation hydrology and its linkages to ecosystem processes, and additionally provides a valuable data set for calibration and validation of remote sensing approaches to measurement of inundation area and water movement across floodplains.

This paper presents an approach enabling a smart card issuer to verify that a new applet securely interacts with already downloaded applets. A security policy has been de ned that associates levels to applet attributes and methods and de nes authorized ows between levels. We propose a technique based on model checking to verify that actual information ows between applets are authorized. We illustrate our approach on applets involved in an electronic purse running on Java enabled smart cards.
