While the last 50 years of agriculture have focused on meeting the food, feed, and fiber needs of humans, the challenges for the next 50 years go far beyond simply addressing the needs of an ever-growing global population. In addition to producing more food, agriculture will have to deal with declining resources like water and arable land, need to enhance nutrient density of crops, and achieve these and other goals in a way that does not degrade the environment. Biotechnology and other emerging life sciences technologies offer valuable tools to help meet these multidimensional challenges. This paper explores the possibilities afforded through biotechnology in providing improved agronomic “input” traits, differentiated crops that impart more desirable “output” traits, and using plants as green factories to fortify foods with valuable nutrients naturally rather than externally during food processing. The concept of leveraging agriculture as green factories is expected to have tremendous positive implications for harnessing solar energy to meet fiber and fuel needs as well. Widespread adaptation of biotech-derived products of agriculture should lay the foundation for transformation of our society from a production-driven system to a quality and utility-enhanced system.

The potential of integrating multiagent systems and virtual environments has not been exploited to its whole extent. This paper proposes a model based on grammars, called Minerva, to construct complex virtual environments that integrate the features of agents. A virtual world is described as a set of dynamic and static elements. The static part is represented by a sequence of primitives and transformations and the dynamic elements by a series of agents. Agent activation and communication is achieved using events, created by the so-called event generators. The grammar defines a descriptive language with a simple syntax and a semantics, defined by functions. The semantics functions allow the scene to be displayed in a graphics device, and the description of the activities of the agents, including artificial intelligence algorithms and reactions to physical phenomena. To illustrate the use of Minerva, a practical example is presented: a simple robot simulator that considers the basic features of a typical robot. The result is a functional simple simulator. Minerva is a reusable, integral, and generic system, which can be easily scaled, adapted, and improved. The description of the virtual scene is independent from its representation and the elements that it interacts with.

The aim of this commentary is to set out a priority research agenda which will make more systematic the evidence base about why investing in a range of 'public health assets' is important for population health. It will rehearse in brief some of the issues that have been raised over the past few years as experience has grown about how to apply the idea to public health practice.

Increases in the rate and extent of lakeshore development along inland lakes in Ontario are adversely impacting water quality. Despite growing awareness, there is a lack of knowledge about the land use policies and tools in place to protect inland lakes in rural Ontario. This research evaluated official plans for water quality protection policies for inland lakes in the County of Renfrew, Ontario to address this gap. The findings suggest that municipalities implicitly link water quality to land use planning policy and fail to incorporate innovative methods to protect water quality.

This paper, which draws on research findings from the NEUJOBS project, encourages EU and national policy-makers to invest in a more comprehensive view of the phenomenon of ‘low-skilledness’. The ‘low-skilled’ label can hide a number of different scenarios: labour market detachment, migration and obsolete skills that are the result of macroeconomic structural changes. For this reason, the authors argue that it is necessary to promote lifelong learning to allow workers to keep pace with new technologies and to shield workers from the risk of skills obsolescence and detachment from the labour market.

Despite the rapidly escalating situation in Ukraine, Michael Emerson discerns in this CEPS Commentary a very slim margin of possibility that cooler heads may still prevail in the Crimean peninsula and allow a return to a mundane and peaceful normality.

The political balance in Sweden was upset in this year’s elections to the European Parliament (EP). The far-right ‘Sweden Democrats’ almost tripled their vote-share and the Greens gained enough votes to become the second-largest Swedish party in the EP after the Social Democrats. Support for the current government incumbents, the Moderates, fell beyond expectation. The party will not recover in time for the national elections in September, whereas both the Greens and the Sweden Democrats are likely to repeat their EP election success. Since the Sweden Democrats are unlikely to form part of the coalition government – the election-winners will be the Greens and Social Democrats – Sweden’s political landscape is set to undergo a shift to the left.
