"Die christliche Nächstenliebe ist ein zentraler Aspekt im Werk Gregors des Großen. Durch die Analyse seines Gesamtwerks zeigt Susanne Barth, wie stark der römische Bischof sowohl sein theologisches Denken als auch sein kirchenleitendes Handeln am Nutzen für den Mitmenschen ausrichtet."

Grasslands cover a significant proportion of the land mass of the world, and play a pivotal role in global food production. At the same time we are faced with several challenges that affect the way in which we think about this valuable set of resources. The population of the world is expected to exceed 9 billion by 2050, and increase of about one third relative to today’s levels. This population increase will be focused in urban areas, and in what are currently viewed as “developing” countries, meaning that the buying power of this increased population will be greater – shifting the balance of demand from staple crops to high value items such as meat and dairy products. Overall that the world will have to approximately double agricultural output across all categories of food to meet the demands of this larger, urbanised population. This is occurring against a backdrop of equally large challenges in terms of global climate change. Agriculture is already a significant contributor to e.g. greenhouse gas emissions, deforestation and soil erosion. The situation is made more complex by an increased emphasis on biofuels as a solution for our imminent oil shortage, resulting in increased competition between land utilised for food and fuel. In short, agriculture must continue to feed the world, whilst not contributing to damaging it further. It must be sustainable. Plant breeding plays a significant but frequently understated role in meeting the challenges presented by this complex and changing scenario. However, plant breeding and improvement is itself undergoing radical change driven by technology. This book explores how forage and turf breeding is changing and adapting to meet these challenges using the technological advances being experienced in plant breeding as a whole.

This book presents a flavour of activities focussed on the need for sustainably produced biomass to support European strategic objectives for the developing bioeconomy. The chapters cover five broad topic areas relating to the use of perennial biomass crops in Europe. These are: ‘Bioenergy Resources from Perennial Crops in Europe’, ‘European Regional Examples for the Use of Perennial Crops for Bioenergy’, ‘Genotypic Selection of Perennial Biomass Crops for Crop Improvement’, ‘Ecophysiology of Perennial Biomass Crops’ and ‘Examples of End-Use of Perennial Biomass Crops’. Two major issues relating to the future use of biomass energy are the identification of the most suitable second generation biomass crops and the need to utilise land not under intensive agricultural production, broadly referred to as ‘marginal land’. The two main categories of plants that fit these needs are perennial rhizomatous grasses and trees that can be coppiced. The overarching questions that are addressed in the book relate to the suitability of perennial crops for providing feedstocks for a European bioeconomy and the need to exploit environments for biomass crops which do not compete with food crops. Bioenergy is the subject of a wide range of national and European policy measures. New developments covered are, for example, the use of perennial grasses to produce protein for animal feed and concepts to use perennial biomass crops to mitigate carbon emissions through soil carbon sequestration. Several chapters also show how prudent selection of suitable genotypes and breeding are essential to develop high yielding and sustainable second generation biomass crops which are adapted to a wide range of unfavourable conditions like chilling and freezing, drought, flooding and salinity. The final chapters also emphasise the need to be kept an eye out for potential new end-uses of perennial biomass crops that will contribute further to the developing bioeconomy.
