Resource Shortage

Klimawandel und Ressourcenverknappung sind die wesentlichen Herausforderungen unserer Zeit, denen sich auch der Massivbau stellen muss. In diesem Beitrag werden zunächst die Herausforderungen wie die stetige Zunahme der verwendeten Betonmenge, Treibhausgasemissionen und Ressourceneffizienz bei der Herstellung von Beton und die wachsende Baunachfrage in den Blick genommen. Mit Bezug zur Struktur des deutschen Bauwesens werden die stagnierende Arbeitsproduktivität als Indikator für ineffiziente Prozesse, das fragmentierte, wenig digitalisierte Planen und Bauen und das kleinteilige, kaum ganzheitlich betrachtete Vorgehen analysiert. Ausgehend von den Herausforderungen und der Analyse der Rahmenbedingungen werden erste Lösungsansätze aufgezeigt: die Planungsoptimierung auf Grundlage digitaler Bauwerksmodelle, die Erhöhung der Effizienz von Betonbauteilen sowie die verlängerte Nutzung von Bestandsbauwerken. Ziel ist es, Beispiele für notwendige Veränderungen aufzuzeigen, ohne den Anspruch auf ein vollständiges oder abschließendes Bild für den klimafreundlichen und ressourceneffizienten Massivbau zu haben.

Environmental Crimes

Balancing between economic growth and environmental protection is the core of sustainable development. However, both developed and developing countries are facing many difficulties in dealing with global challenges such as climate change, pollution and resource shortage. In an effort to promote environmental protection and legislate punishment, environmental crimes have been included in criminal law. In order to increase its effectiveness, criminal law on environmental crimes need to be further specified, such as identification of environmental offences, inclusion of new offences, expansion of scope of application, increase on fine, and supplement existing sanctions for environmental offences. These changes can bring tremendous impacts on Vietnam’s sustainable development in the nearfuture.

Averting robo-bees: why free-flying robotic bees are a bad idea

Insect Interactions

Food security and the sustainability of native ecosystems depends on plant-insect interactions in countless ways. Recently reported rapid and immense declines in insect numbers due to climate change, the use of pesticides and herbicides, the introduction of agricultural monocultures, and the destruction of insect native habitat, are all potential contributors to this grave situation. Some researchers are working towards a future where natural insect pollinators might be replaced with free-flying robotic bees, an ecologically problematic proposal. We argue instead that creating environments that are friendly to bees and exploring the use of other species for pollination and bio-control, particularly in non-European countries, are more ecologically sound approaches. The computer simulation of insect-plant interactions is a far more measured application of technology that may assist in managing, or averting, ‘Insect Armageddon' from both practical and ethical viewpoints.

Abstract We are in a period of relatively rapid climate change. This poses challenges for individual species and threatens the ecosystem services that humanity relies upon. Temperature is a key stressor. In a warming climate, individual organisms may be able to shift their thermal optima through phenotypic plasticity. However, such plasticity is unlikely to be sufficient over the coming centuries. Resilience to warming will also depend on how fast the distribution of traits that define a species can adapt through other methods, in particular through redistribution of the abundance of variants within the population and through genetic evolution. In this paper, we use a simple theoretical ‘trait diffusion’ model to explore how the resilience of a given species to climate change depends on the initial trait diversity (biodiversity), the trait diffusion rate (mutation rate), and the lifetime of the organism. We estimate theoretical dangerous rates of continuous global warming that would exceed the ability of a species to adapt through trait diffusion, and therefore lead to a collapse in the overall productivity of the species. As the rate of adaptation through intraspecies competition and genetic evolution decreases with species lifetime, we find critical rates of change that also depend fundamentally on lifetime. Dangerous rates of warming vary from 1°C per lifetime (at low trait diffusion rate) to 8°C per lifetime (at high trait diffusion rate). We conclude that rapid climate change is liable to favour short-lived organisms (e.g. microbes) rather than longer-lived organisms (e.g. trees).
