Precision agriculture on grassland: Applications, perspectives and constraints

Abstract Precision agriculture (PA) is an innovative, integrated and internationally standardized approach aiming to increase the efficiency of resource use and to reduce the uncertainty of decisions required to control variation on farms. Worldwide, investments in research and technology on PA have considerably increased during the past decades. Advances in agricultural research, combined with application [...]

Pest Control Agents from Natural Products

Abstract Natural products have been used to control animal pests, plant diseases, and weeds since ancient times. Plants have been the most important sources of natural pesticides for centuries and preparations standardized for the active ingredient(s) by modern analytical methods became available in the last decades, making possible the manufacture of reliable products. More recently [...]

Landscape Trajectory Analysis: Spatio-temporal Dynamics from Image Time

Abstract Landscape dynamics can be revealed through analysis of image times series. The temporal development of spatial patterns holds significant information about ecosystem processes. Yet, the tools for the characterization of spatio-temporal structure are few. We describe some of the challenges facing spatio-temporal analysis and demonstrate a method for identifying and measuring pattern in image [...]

Fuzzy Synthetic Evaluation of Water Quality of Hei River System

Abstract Identification of water quality conditions in a river system based on limited observations is an essential task for meeting the goals of environmental management. Various classification methods have been used for water quality estimation. However, a discrepancy frequently arises from the lack of a clear distinction between each water utilization mode, the uncertainty in [...]

Ecology, Engineering, and Economics

Abstract There appears to be increasing evidence that contemporary social and environmental problems and energy shortage are symptomatic of prebreakdown stresses inherent in the technical and socioeconomic organization of our system of production and consumption processes as it evolved under the “explosive” force of the industrial revolution. In an effort to understand these stresses and [...]

Prospects for combining chemical and biological methods for integrated environmental assessment

Abstract …Besides deploying a chemicals-driven strategy for the ecological risk assessment of the pollutants, it is necessary to apply and to explore biological strategies. Consequently, bioassays, biosensors and effect-directed analysis (EDA) to identify pollutants responsible of particular effects have become increasingly important. We give a broad overview of how to assess biological monitoring of ecosystems [...]
