Intake of red and processed meat on the incidence of cancer: Are the risks really relevant?

New insights in improving sustainability in meat production: opportunities and challenges

Treating livestock as senseless production machines has led to rampant depletion of natural resources, enhanced greenhouse gas emissions, gross animal welfare violations, and other ethical issues. It has essentially instigated constant scrutiny of conventional meat production by various experts and scientists. Sustainably in the meat sector is a big challenge which requires a multifaced and holistic approach. Novel tools like digitalization of the farming system and livestock market, precision livestock farming, application of remote sensing and artificial intelligence to manage production and environmental impact/GHG emission, can help in attaining sustainability in this sector. Further, improving nutrient use efficiency and recycling in feed and animal production through integration with agroecology and industrial ecology, improving individual animal and herd health by ensuring proper biosecurity measures and selective breeding, and welfare by mitigating animal stress during production are also key elements in achieving sustainability in meat production. In addition, sustainability bears a direct relationship with various social dimensions of meat production efficiency such as non-market attributes, balance between demand and consumption, market and policy failures. The present review critically examines the various aspects that significantly impact the efficiency and sustainability of meat production.

Review: Why and how to regulate animal production and consumption: The case of the European Union

Throughout the world, animal production faces huge sustainability challenges. The latter are exacerbated in the European Union (EU) by consumption issues linked, in particular, to the health and environmental impacts of meat consumption, and by the increasing societal concerns linked to animal welfare. Simultaneously, animal production may also provide benefits, notably from an economic and nutritional point of view. Some livestock systems, notably grass-based systems, may also offer positive climatic and environmental effects. Animal production is highly regulated in the EU, whereas the consumption of animal products is not (or very lightly) regulated. Many of the negative and positive effects are public goods that are not well taken into account by private actors and markets. Thus, there is legitimacy and scope for public policies aimed at reducing the damage and increasing the benefits of animal production and consumption. The last part of the paper explains how this could be achieved in the EU through a significantly revised and extended Common Agricultural Policy that more closely follows the principles of public economics. Public regulation principles that are proposed have a more general scope and can be adapted to other livestock contexts.
