Accurate estimates of the location, timing, and severity of soil-erosion events on arable land have eluded erosion-prediction technology for decades. Here, for the first time, we demonstrate how a machine learning model can nowcast the occurrence and relatively rank the severity of erosion events on arable field parcels at the regional scale with h...

Heat and drought are major abiotic stressors threatening cereal yields, but little is known regarding the spatio-temporal development of their yield-effects. In this study, we assess genotype (G) × environment (E) × management (M) specific weather-yield relations utilizing spatially explicit weather indices (WIs) and variety trial yield data of win...

Earth observation with advanced, large-scale technologies as satellite piloted Synthetic Aperture Radar (SAR) appear essential to monitor agricultural ecosystems in near future. Radar backscatter e.g. allows insights to crop conditions, soil properties and direct mapping of vegetation growth. Precise SAR pre-processing is a substantial prerequisite...

Crop yields are increasingly affected by climate change-induced weather extremes in Germany. However, there is still little knowledge of the specific crop-climate relations and respective heat and drought stress-induced yield losses. Therefore, we configure weather indices (WIs) that differ in the timing and intensity of heat and drought stress in...

Detection of woody landscape elements using LiDAR data of the Digital Twin Germany

Digital transformation is a key to turn public authorities into organisations that make decisions based on data-driven insights. The use of big geodata can enable public authorities to tackle complex sustainability issues. However, the efficient management of large amounts of geodata through implementing viable data infrastructures represents a maj...

Insect diversity and abundance are decreasing with negative consequences for important ecosystem services. Especially changes in cultivation practices, often summarized as intensification, are discussed as major drivers of insect decline. Recent agri-environmental schemes fail to counteract the declining trends as a) ecologically effective measures...

Environmental, economic, and socio-cultural challenges to agroecosystems are diverse, numerous, and often strongly interlinked in complex ways. To tackle such complex challenges and develop ecologically sensible, socially acceptable, and economically sustainable solutions, traditional approaches in science need to be rethought. Agroecological Livi...

Over the last decade, Drosophila suzukii Matsumura, an invasive pest of soft-skinned fruits, gradually established itself in Europe, often resulting in significant economic losses. In 2011, when D. suzukii was first described for Germany, the Julius Kühn Institut (JKI) started a monitoring program in southwest Germany to study the occurrence and ac...

A relatively recent invasive pest of soft-skinned fruits in Europe is Drosophila suzukii (Spotted wing drosophila - SWD). It has already caused severe economic damages in many fruit-crops and some susceptible grape varieties and seems to have successfully adapted to survive under a variety of conditions. The Julius Kühn Institute (JKI) set up a pri...

The overarching goal of the PAM3D research project is to support farmer in complying with legal regulations, designed to protect terrestrial and aquatic ecosystems from pesticides contamination caused by run-off and erosion from sloping agriculture fields.

SYNOPS a pesticide risk indicator model to assess environmental risk – contribution to and benefits of LOD

The presence and spatial distribution of various landscape elements play an important role in pest occurrence and damages. While high-resolution landscape data is widely available, sampling data are often not gathered with landscape studies in mind. In this presentation, we explore methods to analyse trap-capture data of Drosphila suzukii from sout...

Small water bodies (SWB) are freshwater ecosystems of high ecological relevance. However, they receive considerably higher inputs of pesticides compared to larger water bodies owing to their close connection to adjacent agricultural fields in combination with their low water volume or discharge. Monitoring of the pesticide contamination of lentic a...

The overall objective of PURE is to provide practical IPM solutions to reduce dependence on pesticides in selected major farming systems in Europe. This paper summarises methodological advances with regards to the design and assessment of IPM solutions. The presented case studies include major crops (cropping systems based on wheat or maize), field...

Crop protection in general and apple crop protection in particular often rely on pesticides, although several alternative pest management measures are available. In this context European agricultural policy requires the implementation of Integrated Pest Management (IPM) by 2014. Within IPM, more than one strategy can be practiced but selecting the...

The present study was performed to characterise in-stream pesticide exposure within the Palatinate vineyard region in south-west Germany, evaluate the influence of buffer strip widths and identify mitigation measures for the relevant entry pathways. In-stream water and sediment samples that were taken at nine sampling sites of different buffer widt...

By December 2012, EU Member States must complete and initiate the implementation of the National Action Plans (NAP), that will make it possible to reach the objectives of the new EU directive on the sustainable use of pesticides (2009/128/EC). The German NAP is designed to provide incentives for further risk reduction with the overall goal to reduc...

In this work we propose a novel approach to model realistic spray drift deposition distributions for any distances up to 75 m for arable crops and 150 m for permanent crops. The model can be used in georeferenced exposure and risk assessments of surface waters on landscape and stream segment scale. The approach is described for field crops as an ex...

The development of new and innovative strategies of pesticide use in orchards may contribute strongly to an overall reduction of the environmental risk. To quantify the impact of new strategies on the environmental risk and to analyse the risk-behaviour of farmers it is mandatory to assess the risk potential in the context of the landscape. For thi...

Within the GeoRisk project a new approach for the aquatic risk assessment of plant protection products in Germany is further developed and evaluated. The aim is to establish a more realistic risk assessment to allow simplified and reduced substance specific risk mitigation measures while maintaining the existing level of protection. GeoRisk focuses...

1. Introduction Small streams differ greatly from the standardised water body used in the context of aquatic risk assessment for the regulation of plant protection products in Germany. The standard water body is static, with a depth of 0.3 m and a width of 1.0 m. No dilution or water replacement takes place. Spray drift happens always in direction...

Increasing Bt maize in Germany will consequently lead to a high risk concerning adaptation of the European corn borer, Ostrinia nubilalis (Hübner), populations for Bacillus thuringiensis endot- oxins. Obligatory growing of susceptible maize cultivars by farm- ers as refuge close to Bt fields will sustainably face this develop- ment. The high effici...
