Considering the critical importance of the quality of input data for landslide susceptibility, we investigate the performance improvements that can be achieved by different globally available digital elevation models (DEMs) using different state-of-the-art statistical and machine-learning models. For this purpose we compare the predictive performan...

A detailed understanding of herd types is needed for animal disease control and surveillance activities, to inform epidemiological study design and interpretation, and to guide effective policy decision-making. In this paper, we present a new approach to classify herd types in livestock systems by combining expert knowledge and a machine-learning a...

We present a new modelling framework to address the evaluation of national control/surveillance programs planned in line with the European Animal Health Law (AHL) for livestock diseases. Our modelling framework is applied to the cattle sector in Ireland where there is need for policy support to design an optimal programme to achieve bovine herpesvi...

Many studies report age as a risk factor for BoHV-1 infection or seropositivity. However, it is unclear whether this pattern reflects true epidemiological causation or is a consequence of study design and other issues. Here, we seek to understand the age-related dynamics of BoHV-1 seroprevalence in seasonal calving Irish dairy herds and provide dec...

Bovine Viral Diarrhoea (BVD) has been the focus of a successful eradication programme in Ireland, with the herd-level prevalence declining from 11.3% in 2013 to just 0.2% in 2023. As the country moves toward BVD freedom, the development of predictive models for targeted surveillance becomes increasingly important to mitigate the risk of disease re-...

The poster aims to present the progress and challenges in the eradication of Bovine Viral Diarrhoea (BVD) in Ireland and highlight the unresolved issues that require further research and action.

Research funded by the Department of Agriculture, Food and the Marine, Ireland. Overview of the study estimating the livestock biomass and the related economic value of the Irish cattle sector from 2011 to 2021.

The poster highlights some of the pitfalls when analyzing age-related prevalence data

Summary of a model study to examine the impact and costs of a potential IBR eradication program in Ireland

Background The cattle sector is the most important economic production unit of the Irish farming and agri-food sector. Despite its relevance, there has been limited quantitative information about the structure of differing cattle production types and of the connections between them. This paper addresses this gap by providing, for the first time, an...

Models can be applied to extrapolate consequences of climate change for complex ecological systems in the future. The acknowledged systems’ behaviour at present is projected into the future considering climate projection data. Such an approach can be used to addresses the future activity and density of the castor bean tick Ixodes ricinus, the most...

Die Unterscheidung von Rinderbetrieben nach Produktionsart ist von zentraler Bedeutung für die Entwicklung, Planung und Bewertung von Programmen zur Überwachung von Rinderkrankheiten und des Antibiotikaeinsatzes. Dies ist besonders im Rahmen des neuen europäischen Tiergesundheitsgesetzes (AHL) wichtig, welches unterschiedliche Überwachungsstrategie...

The tropical dry forests of NW Peru are heavily shaped by the El Niño Southern Oscillation (ENSO), where especially El Niño brings rain to arid to semi‐arid areas. However, the resulting effects on biodiversity patterns remain largely unknown as well as the effect of environmental variables on the floristic composition under varying rainfall patter...
