The global uncontrolled rise of antimicrobial resistance (AMR) is a major societal threat and it is well documented that AMR is already negatively affecting healthcare and intensive livestock farming systems. Nonetheless, capture fisheries are still essential to the global food supply providing over 50% of the world’s aquatic organism production. To facilitate improved management, it is therefore imperative that we better understand reservoirs of AMR and how gene transmission occurs in the aquatic environment. In order to discern which AMR bacteria and genes are present in the marine environment, sediment and seawater samples were collected and Atlantic Mackerel were captured at the beginning of summer and autumn in the Solent Strait (Portsmouth, U.K). In addition, commercially available Atlantic mackerel were purchased at a local fish market. Using culture-dependent techniques we obtained more than 700 bacterial and 20 fungal isolates from skin, intestinal lining, and intestinal content. Ten different cefotaxime-resistant Pseudomonas spp. were isolated from the seawater and market fish skin samples, and one cefotaxime-resistant Rhanella sp. was isolated from wild fish digesta. Results from ongoing whole-genome shotgun metagenomics analysis will be discussed, as well as the connection between AMR bacteria and AMR gene presence within the marine coastal environment and the local fish markets, which are the last link between capture fisheries and consumers.

Nutritional Strategies

Reproductive efficiency of farm animals has central consequences on productivity and profitability of livestock farming systems. Optimal reproductive management is based on applying different strategies, including biological, hormonal, nutritional strategies, as well as reproductive disease control. These strategies should not only guarantee sufficient reproductive outcomes but should also comply with practical and ethical aspects. For example, the efficiency of the biological- and hormonal-based reproductive strategies is mainly related to several biological factors and physiological status of animals, and of nutritional strategies, additional factors, such as digestion and absorption, can contribute. In addition, the management of reproductive-related diseases is challenged by the concerns regarding the intensive use of antibiotics and the development of antimicrobial resistant strains. The emergence of nanotechnology applications in livestock farming systems may present innovative and new solutions for overcoming reproductive management challenges. Many drugs (hormones and antibiotics), biological molecules, and nutrients can acquire novel physicochemical properties using nanotechnology; the main ones are improved bioavailability, higher cellular uptake, controlled sustained release, and lower toxicity compared with ordinary forms. In this review, we illustrate advances in the most common reproductive management strategies by applying nanotechnology, considering the current challenges of each strategy.

Nitrates Directive

The previous articles have shown that preoccupations concerning discharge of nitrate emissions are not recent, even if they have not yet resulted in expected reductions. The Water Framework Directive, which aims at a ‘good’ ecological state of all aquatic environments in 2015, enlarges the objectives of the Nitrates Directive. We are currently witnessing the broadening of objectives for reducing emissions of all forms of nitrogen from livestock farming systems to other compartments, in particular the atmosphere. The reduction of ammonia emissions, which was a little concerned by the French context until now, is a priority for animal systems in several northern European countries. It is a subject of intense efforts of international regulations.

Livestock Systems

Pasture-based livestock systems, often located in High Value Nature farmland areas, hold the greatest potential to deliver public goods across European agricultural systems. They play an important role in preserving agricultural landscapes, farmland biodiversity, cultural heritage, and in sustaining rural development. However, many of these functions are ignored in evaluation frameworks because public goods do not have market price and are often ignored in policy design, so farmers do not get the appropriate incentives to provide them. Different conceptual frameworks can be utilized to evaluate the multiple functions or services of these systems: Multifunctional Agriculture, Ecosystem Services, and Total Economic Value. We analyze the common characteristics of these concepts (e.g. they place human benefits and societal demands at the core of their definitions), their specificities (e.g. use of different units of analysis and spatial-temporal scales), and how they can be embedded in the wider concept of sustainability. Finally, we illustrate how the different concepts can be combined to evaluate pasture-based livestock farming systems from a socio-cultural and economic perspective. The public goods (ecosystem services) provided by representative case studies in Mediterranean and Nordic regions are quantified (also in monetary terms) under different environmental/policy scenarios. The results show that there is a clear underestimation of the socio-cultural and economic values of ecosystem services provided by these farming systems. They also show that the social welfare loss linked to further abandonment of livestock farming, and the associated environmental degradation, is very large. From a societal perspective, it is necessary to jointly measure the biophysical, socio-cultural and monetary values of ecosystem services (market and nonmarket) in order to promote the sustainability of pasture-based livestock systems.
