Transport is a key economic sector, supporting economic development and growth, and facilitating exchange. At the same time, motor vehicles are major emitters of gaseous and particulate pollution in urban areas. The transport industry’s quest to limit its impact on the environment and improve road safety continues to drive policy, research and development. Eco-driving is a well-established, aff...

In this paper, the simple eco-grammar systems with prescribed teams of ter Beek [2] are reconsidered. We show that limited L systems can be simulated by such systems. Furthermore, we introduce the concept of programming which is imposed upon the prescribed teams of the systems. Depending on the success of the application of a team to the actual state of the system, it is specified which teams a...

Organizations are under increasing pressure to account for their environmental footprint and to adopt environmental sustainable practices, and information systems can support organizations in becoming more environmentally sustainable. Through the analysis of expert interviews with eleven representatives from organizations concerned with environmental sustainability, and drawing on a conceptual ...

A large amount of work has analysed systems approaches to innovation and investigated associated methods of innovation measurement. However, relatively little of this literature has discussed the measurement of eco-innovation. Policies and measures to promote eco-innovation are hampered by a lack of relevant data and indicators. Hence, the research reported here aimed to assess whether innovati...

Ecological security and environmental sustainability are the foundations of sustainable development. With the acceleration of urbanization, increasing human activities have promoted greater impacts on the eco-spaces that maintain ecological security. Regional key eco-space has become the primary need to maintain environmental sustainability and can offer society with continued ecosystem service...

Climate change is strongly linked to human behavior and technologies, and many of the barriers to sustainable behavior are rather psychological than technological. More sustainable technologies and food products have been introduced to combat climate change, most often labeled with morally loaded labels such as “organic” or “environmentally friendly”. The purpose of this thesis was, first, to g...

Estimates made just before the 21st century indicate that, by the year 2100, Earth may have between 10 and 11 billion people—not quite double the 6 billion population count reached in October 1999. Sustainable use of the planet requires that human needs be met without impairing the integrity of the planet’s ecological life support system. This objective will almost certainly require equity and ...

We briefly present a synthesis of theoretical models in eco-epidemiology which merges the fields of ecology and epidemics. In particular we discuss the role of parasites/pathogens in community assembly formation and species coexistence, as well as the potential of biological control. Recent works have revealed that the complexity in parasite-mediated interactions can alter the dynamic behavior ...
