More water is being allocated to our needs for food, public supply, hydro-electric power and industrial goods to support growing populations and mounting life-style expectations. To achieve this, less water is often being retained for water-dependent ecosystems. Environmental protection agencies and conservation organisations have highlighted the resulting threat to freshwater biodiversity and associated ecosystem services that support human livelihoods and well-being. Careful assessments are therefore required to advise on the optimum allocation of water and to determine the risk of developments that require redistribution of water resources. Along the northern fringes of the Guadalquivir River delta and estuary in southern Spain about 40% of all jobs derive from agriculture. The production of olives, fruit trees, rice and berries is a major component of the local economy producing large exports, but it requires significant water from local rivers and the underlying aquifers. The economy is also reliant on tourism that brings many thousands of people to the area in the summer for which groundwater abstraction is augmented. The delta is the location of the Doñana wetland complex of lagoons, marshlands, fixed and mobile dunes that was designated as a Biosphere Reserve by UNESCO in 1980, as wetland of international importance (Ramsar Site) under the Convention on Wetlands in 1982 and as a World Heritage Site by UNESCO in 1994. Fears have been expressed that increasing human water use is putting the wetlands at risk of drying out, despite efforts by the river basin authority to limit abstraction to sustainable levels. This paper reports on a methodology that analyses best available eco-hydrological scientific knowledge together with information on the likely success of abstraction control measures to determine the risk to the wetland ecosystem of current and future planned water allocation. The method was applied to Doñana by the joint UNESCO/ IUCN/Ramsar Reactive Monitoring mission to in 2020. The results are also provided in the paper, which raised many important scientific and related political, legal and social issues concerning the impacts of water withdrawals on the ecology of the wetlands. The methodology has wide application to environmental water allocation assessments.

The goal of this rapid response assessment, carried out on behalf of UN Environment and based on the efforts of more than 30 contributors, is to raise awareness about the importance of the world's peatlands and to encourage immediate action to preserve them.

Coots nested only on the latter. Nesting success depended on drying out of the marshes, and vegetative cover of the nests provided some protection against aerial predators. The density of nests was lower in marshes which dried out early. The distribution of nests in the marshes was related to the distribution of emergent vegetation at least 30 cm tall. Nest distribution changed during the reproductive period as the peripheral parts of the marsh dried out and new emergent vegetation grew up. Regular nest checks revealed that nesting started earlier in years with high water levels and on marshes with large areas covered by emergent vegetation. Nesting started first on Phragmites marsh and on tamarisk trees, followed with a delay of 10-20 days on a mixed vegetation of Typha and Scirpus. Nests were bes...

River systems provide many services to people, including freshwater provisioning, carbon storage, fisheries, recreation, transportation, and biodiversity. Here, we review the services provided by rivers and describe a conceptual model relating services to drivers, pressures, ecosystem state, and management responses. This approach allowed us to highlight how policies and decisions can lead to trade-offs among services, which must be considered for sustainable watershed management. We have used this conceptual framework to compare two rivers, the Don River in the Russian Federation and the Roanoke River in Virginia/North Carolina, USA, to demonstrate the usefulness of the ecosystem services approach. Future science needs for ecosystem services in rivers are to identify service indicators and map services, link drivers/pressures to services with models, and relate natural systems to social and economic systems.

It is the most important wintering site in the worm for the white-headed duck Oxyura leucocephala, a globally threatened species. It has also hem internationally important numbers of 10 other waterbird species. The lake is threatened by the construction of an industrial complex and airport on the northern shore. Falling water levels (from construction of upstream dams), sedimentation (from catchment erosion), organic pollution (from food processing and sewage) and inorganic effluent (from a sulphur mine) represent long-term threats to the lake system. Illegal hunting from the shore has a serious impact upon white-headed ducks, which concentrate close inshore and show little escape response in the presence of hunters. White-headed duck numbers have fluctuated
