STRATEGIES FOR CIRCULAR AGRICULTURE TO REDUCE GHG EMISSIONS WITHIN AND BETWEEN FARMING SYSTEMS ACROSS AN AGRO-ECOLOGICAL GRADIENT

Challenge

Over the past decades, European farms have trended towards specialization and high per ha yields but have become increasingly dependent on external inputs to compensate for declining recycling of nutrients. Meanwhile, farms in sub–Saharan Africa less specialized, have low inputs and yields and much higher vulnerability to climate change compared with European farms. More efficient (re)cycling of resources (water, energy and land) across the agri-food sector and enhanced resilience is imperative to deliver food security whilst respecting ecological boundaries and rural livelihoods. In Europe, recoupling (direct and/or remote) of livestock and crop systems could play an important role in more efficient (re)cycling of resources across livestock and crops, and food value chains. In Africa, integrating sustainability and resilience objectives with enhanced food security could avoid some of the trade-offs currently experienced in Europe (eg high GHG emissions and N pollution).

Approach

CircAgric-GHG will draw upon state-of-the-art knowledge, research methods and models to assess how circular practices can deliver sustainable food systems Using farm typologies as a baseline, the extent of existing circular practice implementation will be evaluated Promising practices to enhance circularity will be proposed across typologies and agro-ecological zones. High-resolution modelling of resource cycling and GHG emissions at farm and landscape level will be undertaken using process and farm models, with remote sensing of particularly uncertain land-use emission fluxes using novel satellite and drone technology. LCA will be applied to integrate modelling outputs into environmental footprints of food production, developing a novel framework for future projects Farm scale modelling will also inform a marginal abatement cost curve and a decision support tool, enabling robust comparison of GHG abatement efficacy of specific circular practices.

Meanwhile, stakeholder dialogue via workshops and focus groups will identify systemic lock-ins and levers pertinent to wide-scale deployment of circular practices, culminating in a Transition Roadmap Scenario analysis will then integrate farm-scale abatement with macro resource flow and land-use change consequences of promising practices Consequential. LCA will be applied to evaluate the technical potential for circular scenarios to meet 2030 Farm to Fork and 2050 climate neutrality targets, with the screening of major ES effects.Results will be made available in an open-access database. Project partners will engage their stakeholder networks and outreach organisations to leverage impact through transdisciplinary research, maintaining dialogue via social media, workshops and focus groups, as well as traditional academic channels. Emphasis will be placed on the diversity of circular practices needed to improve resource efficiency and sustainability, and GHG abatement across mixed crop-livestock systems at different scales (farm to international).​

The CircAgric-GHG consortium is ideally positioned to deliver impact, spanning a diverse range of farm typologies and agro-ecological zones, representing a wealth of expertise across alternative feeds, ruminant methane mitigation, mixed-species swards, protein-crop rotations, dairy-beef system interconnections, biological waste- and co-product recycling and on-farm bioenergy production. CircAgric-GHG will draw upon data from existing projects, insight from ongoing stakeholder dialogue, and a basket of state-of-the-art scientific methods, in a strategic manner to assess relevant practices at the appropriate scale to shape sustainable food system transitions across Europe and Africa over the coming decades.

First results

Stefano Sari, Luciana Bava, Stefania Colombini and Giulia Gislon (all from UNIMI) visited a farm rearing the italian beef cattle Piedmontese breed (http://www.cascinamonache.it/). The farm is a part of the CircAgric-GHG project and was selected since it is an example of suckler cows to beef system. This system is an alternative to more intense beef cattle rearing systems where animals weighted up to about 450 kilos are imported from other EU-countries and fattened in Italy during the last part of the cycle. During the visit details about farm characteristics were collected.

The project will use various remote sensing technologies to detect CH4 and CO2 fluxes from landscapes and animals.

  • Circular agriculture to improve sustainable food production - Produced by: Ffion Evans, Bangor University. In the past mixed crop livestock farming, a system that grows crops and raise livestock on the same farm, was common. However, driven by economy competitiveness and agricultural policy, production has become more specialized and less connected.  To further explain to the stakeholders the concept of circularity, summarizing how circular agriculture can improve sustainable productions compared to more intensive farming systems.
