Composite health measures are increasingly applied in studies aiming at describing the burden of diseases, and food and water-borne diseases (FWDs) are no exception. The Burden of Communicable Diseases in Europe (BCoDE) is a project led and funded by the European Centre for Disease Prevention and Control (ECDC) with the purpose of encouraging and empowering public health experts in the estimation of the impact of communicable diseases expressed in Disability Adjusted Life Years (DALYs). Calculation of DALYs and a critical assessment of burden of disease outputs require a thorough consideration of a number of methodological and epidemiological decisions ranging from modelling (e.g. incidence versus prevalence), disease model parameters (e.g. risks of developing complications or death) and the data feeding the number of cases.Burden of disease studies produce useful results for public health decision-making, in particular when they aim at informing preventive strategies. For this purpose, we attributed FWDs results from the BCoDE 2015 study to different exposure routes. We discuss these in the more general perspective of generating burden of disease evidence for planning and prioritisation, including the potentials and limitations of its methodology.

The water, energy and food nexus (WEF nexus) is currently quite popular in environmental management. The concept found a fertile ground in science and policymaking, but there is no consistent view on the meaning of integration within the nexus. Here, a wealth of publications is reviewed in an endeavour to: (1) reveal the lines of justification for the need of the WEF nexus debate and (2) identify the range of tools for analysing the interdependent resource issues of the nexus using an integrated framework of science and policy. There are three drivers behind the emergence of the nexus thinking. These are a) increasing resource interlinks due to growing scarcities, b) recent resource supply crises, and c) failures of sector-driven management strategies. Evaluation of the WEF nexus integrative debate can be carried out using four key criteria, namely ability to change current policy debates, issue and thinking novelty, practicability and measurability, and clearness and implementation roadmap. It is clear that, although the nexus has been quite successful in changing policy debates, issue prioritization is missing and seems to be left to specific case studies and policymakers' choices. There is a high need for ‘incorporation’ and ‘cross-linking’ of issues between the three resources. In this regard, nexus governance is the missing link in the nexus debate.

During the past three decades, the Pisque watershed in Ecuador's Northern Andes has become the country's principal export-roses producing area. Recently, a new boom of local smallholders have established small rose greenhouses and joined the flower-export business. This has intensified water scarcity and material/discursive conflicts over water use priorities: water to defend local-national food sovereignty or production for export. This paper examines how including peasant flower farms in the capitalist dream – driven by a ‘mimetic desire’ and copying large-scale capitalist flower-farm practices and technologies – generates new intra-community conflicts over collective water rights, extending traditional class-based water conflicts. New allocation principles in Ecuador's progressive 2008 Constitution and 2014 Water Law prioritising food production over flowers' industrial water use are unlikely to benefit smallholder communities. Instead, decision-making power for peasant communities and their water users' associations on water use priority would enable water user prioritization according to smallholders' own preferences.

Safe and secure access to drinking water and sanitation are human rights that are vital to social, economic, and environmental wellbeing. While interpretations of these rights often focus on domestic water access – for example, whether someone has sufficient drinking water – there is increasing recognition that water for health, food security and nutrition, and basic livelihood needs are inextricably linked. A progressive approach to the human rights to water needs to consider interlinked priorities around food and livelihoods. | Non-PR | 1 Fostering Climate-Resilient and Sustainable Food Supply; IFPRI5 | EPTD

Population and economic growth pose unique challenges in securing sufficient water, energy, and food to meet demand at the sub-national (regional), national, and supra-national level. An increasing share of this demand is met through trade and imports. The unprecedented rapid growth, extent, and complexity of global value chains (GVCs) since the 1980s have reshaped global trade. The GVCs – and new economic patterns of regionalization – affect the demands on water, energy, and food within countries and across global supply chains. East Asia is of particular interest due to the region’s rapid economic growth, substantial population size, high interdependence of the region’s economies, and varying degree of resource availability. While greater interdependence across the region has increased the efficiency of production and trade, these activities require the input of water-energy-food and generate disturbances in the environment. The transnational inter-regional input-output approach is utilized in a tele-connected Water-Energy-Food Nexus (WEFN) analysis of the East Asia GVC to assess competing demands for these resources and environmental outcomes.This analysis demonstrates the hidden virtual flows of water, energy, and food embodied in intra-regional and transnational inter-regional trade. China’s current national export oriented economic growth strategy in East Asia is not sustainable from the WEFN perspective. China is a net virtual exporter of nexus resources to Japan and South Korea. China’s prioritization of economic growth and trade in low value added and pollution intensive sectors consumes a great amount of nexus resources within its territory to satisfy consumers’ demands in Japan and South Korea. Japan’s Kanto and Kinki regions and South Korea’s Sudokwon region were the major beneficiaries while China bore the environmental burden associated with the production of exports. For example, net virtual exports from China’s East region included over 1.2billionm³ of scarce water and 61.3million metric (CO₂ equivalent) tons of greenhouse gases (i.e. CO₂, NH₄, and N₂O) and 2 million metric tons of SOₓ emissions.Trade is an important mechanism for overcoming resource bottlenecks, but, taking into account environmental linkages, regional specialization is not necessarily mutually beneficial. This analysis demonstrates a mismatch between regional water-energy-food availability and final resource consumption and the lack of attention for environmental impacts in national economic growth strategies. Resource scarce countries like China must, therefore, incorporate trade-off decisions between pursuing national economic growth, incurring environmental degradation, and food security into strategic regional development policies.
