Perspectives on the Restoration of the Mississippi Delta. Springer, New York. 194 p.
The purpose of this book is to show how the neglected and degraded landscape of the Mississippi River Delta might be brought back to life. It consists of a collection of scientific essays that focus on applying the results of a new era of scientific discovery to the prospect of large-scale delta restoration. These essays were written by members of the Science and Engineering Special Team (SEST), that began to meet in the aftermath of the Deepwater Horizon disaster of 2010. While this new disaster focused attention on the iconic Birdsfoot Delta, it became clear that few were aware of the way it and the rest of the Mississippi River Delta is being managed nearly into oblivion, largely with public tax dollars and the activities of resource users. The authors seek not only to provide information on ways to halt the ongoing loss of coastal wetlands, but also on how to restore the delta as a fully functional geological and ecological system. The eleven essays contained in this book address some of the challenges facing this process. The book addresses a range of issues including an historical analysis of the delta, river morphodynamics and sediment dynamics, fisheries, flood control and navigation, wetlands and eutrophication, the socio-economic value of the delta, human communities of the delta, and the potential impacts of climate change and energy scarcity. This book clearly presents the enormous challenges facing sustainable management of the delta and charts a way forward. The authors make the clear point that the delta can be restored but that ongoing trends must be taken into consideration and that major restoration must begin soon or it may be too late.

Different contributions of riverine and oceanic nutrient fluxes supporting primary production in Ishikari Bay
Although riverine nutrient ﬂuxes were a major source of DIN and Si(OH)4 nutrient supply in the bay, oceanic nutrient contribution from bottom upwelling and horizontal advection was a major source of PO4. While riverine nutrients signiﬁcantly fuel primary production, the estuarine circulation process may contribute signiﬁcantly to compensating for the inadequate supply of riverine PO4 in an oligotrophic system like Ishikari Bay. Also, unlike the usual estuarine system in which nutrient concentration at a deeper layer is high due to the regeneration of nutrients at depth, concentration in Ishikari Bay was very low due to an inﬂuence of oligotrophic waters. It concludes that riverine nutrient ﬂux contributes a large portion of the total ﬂux in Ishikari Bay.

• IW science and research on LBSP should link natural and social scientists and policy-makers.
• Common frameworks help frame key environmental issues and adaptive management efforts.
• IW science addresses rationales for global research initiatives such as Future Earth.
In 2010 the Global Environment Facility [GEF] developed a medium-sized project on ‘Enhancing the use of science in International Waters projects to improve projects results׳ to examine the role of science and technical analysis in transboundary water projects. This article follows up an analysis of the LBSP working group. The emphasis was on examining the science-policy interface in over forty projects dealing with LBSP. The analytical framework combined descriptive [scientific component-incorporation into project design and implementation], evaluative [extent of use of analytical tools] and prescriptive elements. Best practices for management of LBSP were identified. The prescriptive analysis discussed the importance of enhancing communication among scientists and policy makers. The authors conclude that a common framework [here the DPSIR, further developed as DPSWR approach] should be applied across projects to enable collective framing of the key environmental issues and working towards informal adaptive management.
