TL;DR: In this paper, the authors provide key insights into ecosystem services trade-off analysis at different scales from a land use perspective, by comprehensively reviewing the trade-offs analysis tools and approaches that addressed in ecology, economics and other fields.
Abstract: Ecosystem services are substantial elements for human society. The central challenge to meet the human needs from ecosystems while sustain the Earth’s life support systems makes it urgent to enhance efficient natural resource management for sustainable ecological and socioeconomic development. Trade-off analysis of ecosystem services can help to identify optimal decision points to balance the costs and benefits of the diverse human uses of ecosystems. In this sense, the aim of this paper is to provide key insights into ecosystem services trade-off analysis at different scales from a land use perspective, by comprehensively reviewing the trade-offs analysis tools and approaches that addressed in ecology, economics and other fields. The review will significantly contribute to future research on trade-off analysis to avoid inferior management options and offer a win-win solution based on comprehensive and efficient planning for interacting multiple ecosystem services.

TL;DR: This work investigates how information asymmetry and procurement contracting strategies interact to influence the supply chain parties' incentives to collaborate, and identifies a simple strategy, expected margin commitment EMC, that effectively promotes collaboration.
Abstract: During development of an innovative product there is often considerable uncertainty about component production cost, and it is of interest for both the manufacturer and the supplier to engage in a collaborative effort to reduce this uncertainty and lower the expected cost. Despite the obvious benefits this brings, the supplier may be reluctant to collaborate as he fears revealing his proprietary cost information. We investigate how information asymmetry and procurement contracting strategies interact to influence the supply chain parties' incentives to collaborate. We consider a number of procurement contracting strategies, and identify a simple strategy, expected margin commitment EMC, that effectively promotes collaboration. The manufacturer prefers EMC if collaboration leads to a large reduction in unit cost and/or demand variability is low. Otherwise, a screening contract based on price and quantity is preferred. We also find that, paradoxically, ex post efforts to enhance supply chain efficiency may hinder ex ante collaboration that precedes production.

TL;DR: In this paper, the authors aimed to map and assess water provisioning services and associated benefits to support the ecosystem-water-food-energy nexus by taking into account environmental flow requirements for riverine ecosystems using the hydrological model Soil and Water Assessment Tool (SWAT).
Abstract: Water, food and energy are at the core of human needs and there is a boundless complex cycle among these three basic human needs. Ecosystems are in the center of this nexus, since they contribute to the provision of each component, making it imperative to understand the role of ecosystems in securing food, water and energy for human well-being. In this study we aimed to map and assess water provisioning services and associated benefits to support the ecosystem–water–food–energy nexus by taking into account environmental flow requirements for riverine ecosystems using the hydrological model Soil and Water Assessment Tool (SWAT). We developed a framework that includes indicators of renewable water (capacity of ecosystem to provide water) and water use (service flow) and we applied it in the Danube river basin over the period 1995–2004. Water scarcity indicators were used to map the possible water scarcity in the subbasins, and analyze the spatial match of water availability and water use. The results show that modelling is instrumental to perform the integrated analysis of the ecosystem–water–food–energy nexus; and that spatial mapping is a powerful tool to display environmental availability of water provisioning and regulatory services delivered by ecosystems, and can support the nexus analysis.
