Buffers for biomass production in temperate European agriculture: A review and synthesis on function, ecosystem services and implementation Organic Eprints
Christen, Ben; Dalgaard, Tommy.
In addition to their potential for biomass production, buffer strips on agricultural land have been shown to protect surface water quality by reducing erosion and nutrient leaching, and can play a key role in nature and flood protection, and the design of bioenergy landscapes resilient to climate changes, and the environmental pressures from intensive agriculture. Use of conservation buffers by farmers outside of designated schemes is very limited to date, but the increasing demand for bioenergy and the combination of agricultural production with nature protection calls for a much wider implementation. This paper reviews the knowledge on buffer functioning, socioeconomics and practical farming aspects. It describes how a defined three-zone buffer design,...

Concepts for a multi-criteria sustainability assessment of a new more biobased economy in rural production landscapes Organic Eprints
Dalgaard, Tommy; Jørgensen, Uffe; Kristensen, I.T.; Gylling, M.; Dejgaard, J.; Dubgaard, Alex; Kjeldsen, Chris; Hermansen, J.E.; Turner, K.G.; Christen, Ben; Andersen, P.S..
This study presents a new approach to model the biophysical potentials for increased biomass harvest in Denmark, and a multi-criteria sustainability assessment of the socio-economic and environmental effects of different scenarios for such increased production and new biobased economy in rural landscapes. Thereby the results serve as input to the ongoing productivism – post-productivism debate related to rural spaces in Europe. Empirical results from a case study of large scale conversion to biorefenery technologies, aiming to increase the total Danish harvest of biomass by 10 million tonnes via the conversion to new types of crop production and land management, is used as an example, and will be related to the common conceptual model presented by the...

Possible beneficial effects of biomass for bioenergy crops Organic Eprints
Christen, Ben.
Debate about biomass for heat and/or power generation often revolves around the potential for greenhouse gas (GHG) emission mitigation versus the detrimental effects of growing the crops on biodiversity and landscape aesthetics. This mini review aims to highlight some of the possible beneficial effects of growing bioenergy crops, including other options than the most talked about miscanthus or salix/populus. To keep the text short, it explicitly does not deal with the issue of GHG emission mitigation by substituting non-renewable energy sources with a renewable source and omits all negative impacts that biomass crops may have, highlighting only possible benefits. This strong bias allows for more detailed examination of less common aspects and options...
