“…Additionally, recent studies indicate that when factoring in the land use in third-party importers that will compensate for the domestic yield reduction, organic farming could in some cases increase GHGs net emissions (Smith et al, 2019). Studies also report that GHGs emissions can increase due to the use of organic fertilizers and soil amendments (Shakoor et al, 2021;He et al, 2023). On the contrary, integrated fertilization and pest management strategies could significantly reduce the use of agrochemicals (within the boundaries of EGD) and maintain the yields, without compromising neither the environment, nor consumers' safety (Pretty and Pervez Bharucha, 2015;Tang et al, 2022;Weltin and Hüttel, 2023).…”

The European Union (EU) has been actively combating climate change for decades, and in 2019 it introduced its most ambitious project to date, the European Green Deal (EGD). EGD includes a variety of policies and strategies aimed at mitigating the adverse effects of climate change, foster an economic growth, and promote social equity. Recently, the European Commission has been contemplating the development of the European Blue Deal (EBD), which aims to address the growing water crises and water insecurity issues within the EU. Similar to the EGD, the EBD would encompass all sectors of the European economy, seeking integrated solutions to these pressing environmental problems. This review aims to assess the progress of the EGD, evaluate the objectives of the EBD, and provide insights into the factors that could either catalyze or hinder their effective and harmonious implementation. The concept of a "Teal Deal" (a combination of the blue and green color) which combines elements of both the EGD and the EBD, is explored, with particular emphasis on its implications for the agrifood sector. Here we argue on the necessity for a holistic approach to agricultural sustainability, rapid advancements in renewable energy, the adoption of crop diversification strategies, and the development of effective international policies to ensure global cooperation and support for these transformative initiatives. By addressing these key areas, the EU can make significant strides towards achieving its environmental and economic goals.

This study undertakes a comprehensive analysis of vegetable production efficiency in China using input–output data from 30 provinces spanning 2011 to 2017. By incorporating environmental pollution costs as undesirable outputs alongside vegetable output value, we employ Data Envelopment Analysis (DEA) with the Banker, Charnes, and Cooper (BCC) model and the Malmquist index model. Our assessment reveals both annual and inter-period efficiency changes. The findings highlight a modest overall efficiency in China’s vegetable production and significant regional disparities. Technical progress emerges as a pivotal determinant of total factor productivity (TFP). Recognizing these dynamics, we propose policy recommendations that prioritize technical innovation, sustainable practices, rural infrastructure enhancement, and specialized cultivation methods. Implementing these recommendations could bolster China’s position in international trade negotiations due to increased exports and potentially drive broader environmental policy reforms. As vegetable production becomes more efficient and sustainable, there might be a shift in labor needs, potentially leading to migration patterns or changes in employment structures. These insights contribute to the sustainable development of China’s vegetable industry, offering a broader understanding of the dynamics of agricultural efficiency in the context of environmental sustainability.

“…Numerous studies have investigated the impacts of fertiliser application on GHG fluxes, mainly N 2 O, from agricultural soils (Inselsbacher et al 2010;Mateo-Marin et al 2020;Adelekun et al 2021). The overarching consensus is that soils amended with organic fertiliser have higher N 2 O and CH 4 emissions than those amended with inorganic fertiliser (Thangarajan et al 2013;Walling and Vaneeckhaute 2020;He et al 2023). The effects of using plasma-treated slurry as an organic fertiliser on soil N 2 O and CH 4 emissions is relatively unknown, however, and most of the existing research on plasmatreated organic waste has focused on the effects of plasma-treated cattle slurry on crop yield, soil biota and NH 3 emissions (Mousavi et al 2022;Cottis et al 2023).…”

The use of livestock waste as an organic fertiliser releases significant greenhouse gas emissions, exacerbating climate change. Innovative fertiliser management practices, such as treating slurry with plasma induction, have the potential to reduce losses of carbon and nitrogen to the environment. The existing research on the effectiveness of plasma-treated slurry at reducing nitrous oxide (N2O) and methane (CH4) emissions, however, is not comprehensive, although must be understood if this technology is to be utilised on a large scale. A randomised block experiment was conducted to measure soil fluxes of N2O and CH4 from winter wheat every two hours over an 83-day period using automated chambers. Three treatments receiving a similar amount of plant-available N were used: (1) inorganic fertiliser (IF); (2) pig slurry combined with inorganic fertiliser (PS); (3) plasma-treated pig slurry combined with inorganic fertiliser (TPS). Cumulative N2O fluxes from TPS (1.14 g N m−2) were greater than those from PS (0.32 g N m−2) and IF (0.13 g N m−2). A diurnal pattern in N2O fluxes was observed towards the end of the experiment for all treatments, and was driven by increases in water-filled pore space and photosynthetically active radiation and decreases in air temperature. Cumulative CH4 fluxes from PS (3.2 g C m−2) were considerably greater than those from IF (− 1.4 g C m−2) and TPS (− 1.4 g C m−2). The greenhouse gas intensity of TPS (0.2 g CO2-eq kg grain−1) was over twice that of PS (0.07 g CO2-eq kg grain−1) and around six times that of IF (0.03 g CO2-eq kg grain−1). Although treating pig slurry with plasma induction considerably reduced CH4 fluxes from soil, it increased N2O emissions, resulting in higher non-CO2 emissions from this treatment. Life-cycle analysis will be required to evaluate whether the upstream manufacturing and transport emissions associated with inorganic fertiliser usage are outweighed by the emissions observed following the application of treated pig slurry to soil.
