| In the analysis, we will - identify the most significant changes over time in relevant market, regulatory, institutional and territorial conditions, - assess the social, economic and other resources available among different groups of primary producers, - relate conditions and resources to the (adaptation) strategies pursued (e.g. regarding the management of the chain and risks), and - explore the (potential) impacts of the resulting (or expected) changes on social, economic and environmental performances. The analysis aims at capturing the interrelationships between external and internal conditions, (adaptation) strategies and (sustainability) performance. A first important step in the analysis is to express conditions, strategies and... |

| The mountainous northwest of Vietnam is home for the majority of the country’s ethnic minorities. Poverty and food insecurity are common in the region, increasing population and land scarcity have induced the expansion of agricultural areas and consequent decline of land productivity due to soil erosion and land degradation. Local farmers have begun to practice agroforestry through the introduction of high value trees into traditional cropping systems with various combinations of timber, fruit, nut forage trees and annual crops. However, because of inherent production risks and many remaining uncertainties, assessing the long-term performance of agroforestry has remained challenging. We simulated prospective system benefits of agroforestry options by... |

| Bei heterogenen Bodenverhältnissen - die für eine Vielzahl von Regionen und Landschaften charakteristisch sind - entscheidet primär die Auswahl der Versuchsfläche über die erfolgreiche Durchführung von Feldversuchen. Der Auenboden des Untersuchungsstandortes - Versuchsbetrieb für Organischen Landbau "Wiesengut", Hennef nahe Bonn - weist kleinräumig teilweise innerhalb weniger Meter wechselnde Bodenverhältnisse auf und schränkt damit die Durchführung von pflanzenbaulichen Feldversuchen ein. Für die gezielte Auswahl geeigneter Feldversuchsflächen wurde ein Kriterienkatalog erarbeitet, der folgende Datenbereiche umfaßt: Tachymetrische Vermessung - Kartenwerk der bodenbedingten Bestandesunterschiede; Multitemporale und multispektrale Luftbildaufnahmen;... |

| Yield differences and trends, organic matter accumulation, and the loss of nutrients to deeper soil horizons are discussed using data from organic and conventional maize/tomato cropping systems from the Long Term Research on Agricultural Systems Project (LTRAS) at the University of California, Davis. Compared to the conventional system, higher and increasing yields of tomatoes were observed in organic systems, but lower yields of maize. Fruit quality, measured as soluble solids, was not significantly different. Soil organic matter increased in the organic system, but remained stable in the conventional one. More irrigation water was used in the organic system than in the conventional one due to higher rates of infiltration, but less winter runoff... |

| Circadian rhythms established by the endogenous clocks enable organisms to anticipate periodic and cyclic changes in their environment. This internal time-keeping system is highly conserved amongst animals and provides them with adaptive advantages as biological processes can be scheduled to occur at the most crucial times of the day. Circadian rhythm is emerging as an important regulator of immune functions. However, there is a paucity of information on the influence of this biological phenomenon in the immune mechanisms of teleost fish. A series of studies was conducted to investigate the circadian rhythms of systemic and mucosal innate immunity using model (i.e., zebrafish, Danio rerio) and non-model (i.e., permit, Trachinotus falcatus; rainbow trout,... |

| Ein besseres Verständnis der Dynamik hinter der Freisetzung von pflanzenverfügbaren Nährstoffen aus Boden oder organischen Dünger und eine Verbesserung der Nährstoffverwertung von Ackerfrüchten sind zwei wichtige Herausforderungen, um die Produktivität im ökologischem Ackerbau zu erhöhen. Doch diese Prozesse sind stark sowohl von biotischen (z.B. Bodenmikroben) als auch abiotischen (z.B. Temperatur, Niederschlag, Bodenfeuchtigkeit, Bodenstruktur) Faktoren beeinflusst und erschweren effiziente Untersuchungen. Fernbilderkundung-Technologien (remote sensing) haben sich in den letzten Jahren stark weiterentwickelt und bieten heute neue Ansätze und Methoden, um der Ernährungsstatus von Pflanzen sowie die Dynamik des Pflanzenwachstums nicht destruktiv zu... |

| Earthworms are key organisms and indicators of soil quality, which also links to the productivity of an ecosystem. The higher the earthworm density and diversity, the better the earthworm’s living conditions and the more fertile is the soil. They are relatively easy to detect and determine into three ecological groups. The number and distribution of the three ecological categories and the numerous earthworm species depends on soil management, soil type, the Vegetation and climate conditions. In this technical note, various methods how to sample, measure and interpret earthworms are shown. |

| Detta utbildningsmaterial om emergianalys vänder sig till universitets- och högskolestuderande samt övriga intresserade av analysverktyget emergianalys. Materialet består av en animerad textdel, som översiktligt beskriver metodiken och teorin bakom verktyget, samt en serie exempel och övningsmallar. Exempel och övningsmallar är avsedda att stimulera till egen akademisk lek med verktyget emergianalys. Utbildningsmaterialet gör inte anspråk på att vara heltäckande utan används med fördel i samband med en kurs eller gruppdiskussioner kring resursanvändning och miljöpåverkan ur ett systemperspektiv. Eftersom metodiken kring emergianalys utvecklas mycket snabbt, rekommenderar jag läsaren att komplettera med den senaste vetenskapliga litteraturen inom... |

| The development of scenario analysis (SA) to assist decision makers and stakeholders has been growing over the last few years through mainly exploiting qualitative information provided by experts. In this study, we present SA based on the use of qualitative data for strategy planning. We discuss the potential of SA as a decision-support tool, and provide a structured approach for the interpretation of SA data, and an empirical validation of expert evaluations that can help to measure the consistency of the analysis. An application to a specific case study is provided, with reference to the European organic farming business. |

| Life Cycle Assessment (LCA) is a method that can be used to assess the environmental impact of agriculture, but impact categories and the functional unit of classical LCA’s must be adapted to the specific agricultural production process. Serving as an example, the framework of a LCA of 18 grassland dairy farms covering three farming intensity levels and carried out in the Allgäu region in southern Germany is presented. By focussing on the chosen impact categories and the respective, suitable functional units, the specific needs and backgrounds of conducting an agricultural LCA are discussed in general. aus: Haas, G. und Wetterich, F. und Geier, U.

| The aim of this handbook of experimental guidelines is to help conduct experiments for organic horticulture in greenhouses throughout Europe. It considers vegetables, fruit and ornamental production. Using standardised research procedures for experiments will aid a comparison of results and dissemination of knowledge. The editors have tried to incorporate as many climatic zones, countries and crops as possible in order to represent a wide area of Europe although some smaller crops or certain specific climates could not be included. |
