“…The concepts that make up this cluster refer to air pollution and the negative consequences that bad agricultural practices imply, as well as to the lack of actions to implement CE. Examples of the investigations studying this issue are the documents under the titles "How to reduce the carbon footprint of an irrigation community in the southeast of Spain by use of solar energy" and "Mitigating ammonia and greenhouse gas emissions from stored cattle slurry using agricultural waste, commercially available products and a chemical acidifier" [82,83].

In this current and global context led by scarcity of resources, environmental degradation, global climate change, and a progressive demand for food, the circular economy (CE) represents a key economic model or framework for sustainable, restorative, and regenerative agriculture. Hence, CE applied to agriculture seeks to close the life cycle of products, services, waste, water, and energy to obtain a better use of resources and a reduction of the ecological impact. An initial review of the literature corroborates the hypothesis that the CE framework has not yet been comprehensively adapted to the field of agriculture. This research seeks to overcome this gap in relation to the performance of the circularity of agricultural production systems in support of decision-making processes. A bibliometric analysis of 1060 documents was carried to synthesize the knowledge base on this topic. The results show recent studies that identify weaknesses derived from food production, such as waste generation, biomass, water pollution, and greenhouse gas emissions. It has been identified how their analysis has developed to date and what terms allow us to visualize new approaches; consequently, it is a useful tool for researchers and sponsors who provide financial resources for the development of new lines of research.

Kavanagh et al (2020) hebben een scala aan organische producten toegevoegd aan de drijfmest om de pH biologisch te verlagen en daarmee de emissies te reduceren.

“…Alleen de toevoeging van melasse 5% leidde tot een zodanige pH verlaging dat de emissie van ammoniak daadwerkelijk verlaagd werd (ibid.). Methaanemissies nemen in de meeste gevallen toe omdat er enerzijds onvoldoende pH-verlaging optreedt voor de methanogenese en er anderzijds makkelijk afbreekbare organische stof wordt toegevoegd (Bussink et al, 2014;Melse et al, 2015 ;Kavanagh et al, 2020).…”

Perspectief van het aanzuren van mest in Nederland om methaan-en ammoniakemissie te reduceren. Wageningen Livestock Research, Rapport 1375.Samenvatting NL: Het aanzuren van mest is een kansrijk principe om de methaan-(uit mest) en ammoniakemissies te reduceren. Mest aanzuren heeft echter in Nederland geen voet aan de grond gekregen, onder andere door de hogere kosten van deze systemen ten opzichte van ammoniakemissiearme vloeren, de noodzaak van een externe mestopslag, zorgen over de mogelijke risico's op verzuring en verhoogde concentratie zwavel in de bodem en in het grond-en oppervlaktewater. Ten aanzien van emissies lag in Nederland lange tijd de focus met name op ammoniak. Vanwege de problematiek van klimaatverandering en de internationale en nationale klimaatdoelstellingen is daar de noodzaak bijgekomen om methaanemissies in de landbouw te beperken. In samenhang met de hardnekkige stikstofcrisis en de behoefte aan integrale oplossingen zou de balans ten aanzien van mest aanzuren mogelijk naar de andere kant kunnen omslaan.Het doel van deze studie is daarom om kansen en belemmeringen voor de implementatie van systemen voor het aanzuren van mest in Nederland te identificeren.Summary UK: The acidification of manure is reported as a promising measure for reducing the emissions of ammonia and (manure related) methane. However, this measure has not been implemented in the Netherlands because of, among other reasons, the high costs compared to available flooring systems, the need for manure storage outside the barns, and concerns about the possible acidification of the soil and an increased concentration of sulfur in soils and surface water. Regarding emissions, the focus in the Netherlands was mainly on ammonia. Due to climate change and related national and international agreements, objectives are also being formulated regarding methane emissions. Therefore, the aim of this research is to identify opportunities and barriers for the implementation of manure acidification in the Netherlands.

“…added in feed reduces from 80% up to 98% of CH 4 emissions from livestock, depending on feed digestibility [ 85 , 86 ]. Other feed additives, such as 3-nitrooxypropanol (3-NOP) synthetic product [ 87 ] and other alternatives have been studied such as slurry chemical amendments [ 88 ] and protected urea [ 89 , 90 , 91 ] to reduce overall livestock GHG emissions. However, most are still being studied.…”

Current livestock practices do not meet current real-world social and environmental requirements, pushing farmers away from rural areas and only sustaining high productivity through the overuse of fossil fuels, causing numerous environmental side effects. In this narrative review, we explore how the Voisin Rational Grazing (VRG) system responds to this problem. VRG is an agroecological system based on four principles that maximise pasture growth and ruminant intake, while, at the same time, maintaining system sustainability. It applies a wide range of regenerative agricultural practices, such as the use of multispecies swards combined with agroforestry. Planning allows grazing to take place when pastures reach their optimal resting period, thus promoting vigorous pasture regrowth. Moreover, paddocks are designed in a way that allow animals to have free access to water and shade, improving overall animal welfare. In combination, these practices result in increased soil C uptake and soil health, boost water retention, and protect water quality. VRG may be used to provide ecosystem services that mitigate some of the current global challenges and create opportunities for farmers to apply greener practices and become more resilient. It can be said that VRG practitioners are part of the initiatives that are rethinking modern livestock agriculture. Its main challenges, however, arise from social constraints. More specifically, local incentives and initiatives that encourage farmers to take an interest in the ecological processes involved in livestock farming are still lacking. Little research has been conducted to validate the empirical evidence of VRG benefits on animal performance or to overcome VRG limitations.
