Weather extremes can drive substantial crop losses. Farm-level management strategies play a critical role in mitigating the impacts of and consequences for farmer livelihoods and food security. While the impacts of extreme weather on crop yields are well documented in recent studies, these predominantly focused on expansive geographical scales and...

(1) Introduction: Antimicrobial agents have played an important role in improving the productivity of worldwide livestock production by reducing the impact of livestock diseases. However, a major drawback of antimicrobial use is the emergence of antimicrobial-resistant pathogens in food-producing animals. To reduce the use of antimicrobials, it is...

The Nitrate rapport 2020 containing the results of monitoring effects of the EU Nitrates Directive action programmes Over the past thirty years, the Netherlands government has taken measures to reduce nitrogen and phosphorus concentrations. This has improved the quality of ground and surface water. However water quality is not yet adequate everywhe...

Antimicrobial resistance is one of the biggest health threats for both humans and animals. This justifies the need for a conceptual framework that provides an integrated assessment of the measures and strategies that can be applied within livestock supply chains to reduce the risks of human exposure to resistant pathogens. The aim of this study is...

The aim of the present study was to explore the relation between both farm performance and antimicrobial use (AMU) of broiler farms. Farm performance was expressed as technical efficiency, obtained by using a bootstrap data envelopment analysis. AMU was expressed as treatment incidence. Cluster analysis is used to obtain groups of farms with simila...

Antimicrobial resistance is a global threat for both human and animal health. One of the main drivers of antimicrobial resistance is inappropriate antimicrobial use in livestock production. The aim of this study was to examine the technical and economic impact of tailor-made interventions, aimed at reducing antimicrobial use in broiler production....

Development of antimicrobial resistance (AMR) is considered to be one of the main human health problems. Livestock production, particularly hog and broiler production, are regarded as sources of human exposure to resistant pathogens. It is envisaged that the issue of AMR will be on the agenda of both policy makers at various levels (e.g. supra-nati...
