| In recent years there has been a great deal of interest in assessing the sustainability of agriculture in terms of its social, environmental and economic impact and a number of indicators and tools are used. Measurements take place at the farm or product level and indicators can be outcome related e.g. number of butterfly species present, or management related e.g. percentage of fields with margins growing wildflowers to attract butterflies. Given its underlying ethos, the organic/ecological agriculture sector should aim to be at the forefront of sustainability. The development of assessment approaches and recent discussions within the movement have identified continuous improvement towards best practice in sustainability to be one of the important... |

| A pesquisa buscou analisar a dinâmica de uso e ocupação das terras no município de Bonito (MS), entre os anos de 1986 e 2004, através de técnicas de geoprocessamento e sensoriamento remoto, com vistas a subsidiar estratégias de planejamento do uso e ocupação ideal para a região. Houve a criação de um banco de dados georreferenciados para as análises, numa dinâmica espacial e temporal. No período avaliado, a vegetação nativa passou de 58,30% para 48,10% da área total do município, enquanto que as áreas antropizadas aumentaram de 41,70% para 51,90%. Bonito deve estabelecer estratégias de ações direcionadas ao uso racional das terras, principalmente para as áreas de cerrado típico (cerrado sensu stricto), de acordo com a legislação ambiental em seus... |

| Das Ziel eines geschlossenen Nährstoffkreislaufes auf der Betriebsebene ist ein grundlegendes Leitprinzip des ökologischen Landbaus. Aus der Sicht der Tierernährung bestehen jedoch erhebliche Zweifel hinsichtlich der Übereinstimmung mit den realen Verhältnissen und mit dem Ziel einer nachhaltigen Erzeugung von Produkten tierischer Herkunft. Zur Auswertung kamen veröffentlichte Betriebsbilanzen aus der ökologischen Milchviehhaltung bezüglich Futtermittelzukauf und Nährstoffsaldo, um die Größenordnungen der Nährstoff-Importe in Öko-Betriebssysteme zu bewerten. Die Bilanzen weisen auf Nährstoffimporte von N, P und K in beträchtliche Mengen über zugekaufte Futtermittel und zeigen großen Unterschiede zwischen den einzelnen Betrieben. Vom Ziel eines weitgehend... |

| Today, and especially in the years to come, agriculture, as well as all other human activities, will have to pay much more attention to their environmental impacts. In other words, it is expected that in the near future only technologies which care about environmental aspects will be promoted and accepted by policy makers, scientists, consumers, and society in general. This is not surprising since the environmental problems are among the most urgent ones our civilization will have to tackle and solve. This demand for more careful stewardship of environment is also acknowledged by philosophy of sustainable development - a widely recognized concept and necessity of future development. Although established at the very beginning of this century, ecological... |

| While the role of livestock in sustainable food systems is heavily debated, recent studies show that livestock can contribute to global nutrition security by converting leftover streams – products humans cannot or do not want to eat - into animal-source food (ASF). Where these studies clearly underpin livestock’s role in global food security, the current study aims to identify which combination of livestock systems, differing in production level, can optimally convert leftover streams into protein. To this end, we developed an optimization model containing a variety of livestock systems (pigs, dairy cattle, beef cattle, laying hens and broilers), differing in production level (low, mid and high), to enable better utilization of the various (low quality)... |

| This study was part of a three-year (2004-2007) project entitled "Assessment and reduction of heavy metal inputs into Finnish agro-ecosystems" that was funded by the Ministry of Agriculture and Forestry in Finland. The main aim of this study was to estimate field balances of trace elements at the farm level on typical crop and dairy farms in Finland in 2004. Field balances estimated at the farm level showed that the balances of the harmful heavy metals, Cd and Hg, were often slightly positive leading in accumulation of these metals into the soil on the crop and dairy farms. Selenium indicated a highly positive balance resulting in enrichment of this element in the soil in both farming systems. Also, the Cu and Zn balances were positive on the dairy... |

| The problems of overproduction within the European Union countries and the environmental impact of agriculture have lead to the introduction of schemes that aim to reduce both. Beef (Bos taurus) production forms a large component of the Irish agricultural industry and accounts for more than one quarter of agricultural economic output. Recently, the European CAP (Common Agricultural Policy) has been re-evaluated to include supplementary measures that encompass the environmental role of agriculture rather than just the production role. A life cycle assessment (LCA) method was adopted to estimate emissions per kilogram of CO2 equivalent per kilogram of live weight (LW) leaving the farm gate per annum (kg CO2 kg−1 LW yr−1) and per hectare (kg CO2 ha−1 yr−1).... |

| Dramatically increasing urbanization is observable worldwide and brings pressure on space within urban areas as the built environment intensifies. Considerable evidence suggests that contact with nature is important for city dwellers, although it is not known whether residents’ appreciation of the forms of urban green spaces is constant across different contexts. More specifically, it has not yet been shown whether our appreciation of nature is innate and inherently human, is cultural and something that we learn, or is a mixture of both. This article describes an exploratory study consisting of 17 interviews carried out in Zurich, Switzerland. Kelly’s repertory grid technique is used to identify preferred urban landscapes, which were contrasted with... |

| There is a need for valid and representative data on the production,resourceuse and emissions from different farm types in Denmark for publicregulation and assessment.The data should be usable for both area-based environmental assessment(e.g. nitrate leaching per ha)and product oriented environmental assessment(e.g. greenhouse gas emissions per kg pork).The objective of this study was to establish a national agricultural model for estimating data on resource use, production and environmentally important emissions for aset of representative farmtypes. Every year a sample of farm accounts is established in order to report Danish agro-economical data to the ‘Farm Accountancy Data Network’ (FADN), and to produce ‘The annual Danish account statistics for... |

| The study was conducted in Puruzinho lake (Humaitá, AM) considering seasonal periods of rainy and dry in way to elucidate the flood pulse importance in the deposition, remobilization and distributions of mercury and organic matter in bottom sediments in the Madeira River Basin (Brazilian Amazon). Bottom sediments and soils samples were analyzed for total mercury and organic matter. Mercury concentrations obtained in bottom sediment were 32.20-146.40 ng g-1 and organic matter values were 3.5 - 18.0%. The main region for accumulation of mercury and organic matter was in the central and deepest lake area In the rainy season there was a greater distribution of Hg and organic matter, mainly controlled by means of income of the Madeira river water during... |

| The current situation of worldwide concern over the emission of greenhouse gases and its effect on the climate demands an evaluation, from the perspective of energy efficiency and more specifically of non-renewable energy sources, of tendencies for change in the management of agricultural systems that have arisen in recent years. This article uses energy balances to evaluate the contribution of organic agriculture to the increase in the energy efficiency of Spanish agriculture. The results show the higher nonrenewable energy efficiency (NREE) and the lower use of nonrenewable energy (NRE) in organic systems compared with conventional ones. Nevertheless, agricultural systems in general could still improve their energy efficiency. |
