Environmental Labelling of Food
(2011)An invited conference presentation that discussed the finding of a recent state-of-the-art review into environmental labelling of food that lead to polict recommendations to Defra for teh way forward for the UK. -
Environmental labels for food : Scientific, practical and economic issues
(Food Ethics Council, 2010-09-14)A report of the Business Forum meeting on 14th September 2010 -
Environmental Management For Agriculture (EMA) : A Catalyst for the Evolution of Sustainable Agriculture
(2000-04-10)The potential environmental impacts from agriculture can be diverse. They can be local and site-specific, such as damage to biodiversity and landscape, or more global in nature, such as emissions of ammonia and greenhouse ... -
Environmental Management for Agriculture: Grass & livestock enterprises. : Final report to Defra and Milk Development Council, NT1908, CSA 2628.
(Department for Environment, Food and Rural Affairs (Defra), 1998) -
Environmental management for arable agriculture : An Eco-rating system for pesticide use
(1996)The University of Hertfordshire, funded by MAFF and in collaboration with ADAS and IACR-Rothamsted, is currently developing a computer-based decision support system to encourage and enhance best practice within arable ... -
Environmental Management in Agriculture : An expert system approach
(1996-02)The development of quantitative measures for self-assessment of the environmental performance of farming enterprises is described. A rule-based expert system approach is adopted based on well established sources of guidance. ... -
Environmental sustainability or commercial viability? : The evolution of the EC regulation on genetically modified foods
(1996-03)In October 1995 the Council of Ministers of the European Community finally agreed a common position on a regulation on novel foods and food ingredients. Environmental, organic agricultural and consumer and health concerns ... -
The Environments of Active Galaxies over Cosmic Time
(University of Hertfordshire, 2014-05-27)The overall aim of this thesis is to investigate the environments of AGN, in particular, the density of galaxies in the environments of radio-loud and radio-quiet AGN. This determines whether AGN trace dense environments ... -
The environments of FR II radio sources
(Astronomical Society of the Pacific, 2001)Using ROSAT observations, we estimate gas pressures in the X-ray-emitting media surrounding 63 FR II radio galaxies and quasars. We compare these pressures with the internal pressures of the radio-emitting plasma estimated ... -
The environments of FRII radio sources
(2000)Using ROSAT observations, we estimate gas pressures in the X-ray-emitting medium surrounding 63 FRII radio galaxies and quasars. We compare these pressures with the internal pressures of the radio-emitting plasma estimated ... -
The Environments of High Redshift Active Galactic Nuclei
(2012-08-30)In this thesis I study the links between Active Galactic Nuclei (AGN) and their surrounding large scale environments mainly at high redshift. I firstly use Spitzer space telescope data for one of the largest and most ... -
The environments of radio-loud AGN from the LOFAR Two-Metre Sky Survey (LoTSS)
(2018-10-10)An understanding of the relationship between radio-loud active galaxies and their large-scale environments is essential for realistic modelling of radio-galaxy evolution and environmental impact, for understanding AGN ... -
The environments of z ~ 1 active galactic nuclei at 3.6 μm
(2010)We present an analysis of a large sample of active galactic nuclei (AGN) environments at z∼ 1 using stacked Spitzer data at 3.6 μm. The sample contains type 1 and type 2 AGN in the form of quasars and radio galaxies, and ... -
