Abstract The Canary Islands are a Spanish archipelago, where the greatest water demand comes from agriculture. Being an outermost European region that receives a large number of tourists per year, the need for greater food sovereignty becomes more important. It is vital to undertake studies on the water footprint (WF) of the main crops, in order to identify the irrigation practices of local farmers and establish recommendations for water saving through improvement of these practices. The results of this study show that the average WF for bananas in the Canary Islands is 340.80 m3 t−1 ± 34.07 and for avocadoes is 1741.94 m3 t−1 ± 286.16. The WF models proposed can explain 92 and 86% of the total variance of the WF for banana and avocado crops, respectively. The WF of both crops can be reduced, and this work can be a starting point for improvement. Farmers will face a change in temperature and water availability due to climate change; useful water saving strategies for local farmers can now be made based on estimation of the WF with yield and net needs data.

Abstract Although the impacts of intensive agriculture on biodiversity and strategies for mitigating these effects have been widely described, small-scale, diversified farms and the opportunities they present for bird conservation have been less thoroughly examined. This omission is potentially significant, because this form of agriculture represents a growing sector of the industry in the populous northeastern USA, and the diverse habitats on these farms contrast with larger, structurally homogeneous intensive agriculture. To evaluate bird-habitat associations and conservation opportunities for supporting species of conservation concern on these small, diversified farms, we conducted avian point count and vegetation surveys across 23 farms in western Massachusetts during the summers of 2017 and 2018. We used Poisson-binomial mixture models and canonical correspondence analysis to assess the effects of a suite of microhabitat-, field- and landscape-scale (1 km buffer around the field) variables on the abundance of bird species. Our results confirmed that shrubland birds, a group of species of elevated conservation concern, accounted for 52% of the total observations, including song sparrow (Melospiza melodia), gray catbird (Dumatella carolinensis), common yellowthroat (Geothlypis trichas) and American goldfinch (Spinus tristis). Species–habitat relationships were diverse; however, smaller field sizes, and increased cover of tall, dense, woody or non-productive vegetation types were associated with higher abundance of shrubland species as well as lower abundance of crop pests such as European starling (Sturnus vulgaris) and house sparrow (Passer domesticus). These findings support the hypothesis that small, diversified farms are supporting birds of high conservation concern, and we provide species-specific guidelines for farmers interested in conserving birds on their land.

Abstract Barley is one of the most consumed cereals, with many different cultivars available worldwide. Like other crops, its yield has been affected by climate change and soil degradation. This work proposes controlled-release protein-based matrices with incorporated zinc to improve barley seed germination and zinc content in the plant. Thus, the main objective of this study was to investigate the use of controlled-release protein-based matrices for massive crops, such as barley. Different barley cultivars of barley were studied: Barke, Golden Promise, Morex, WB-200, WB379, and WB-446. The seeds of each cultivar were also analyzed in order to explain the behavior of plants observed during the growth. To this end, the physico-chemical (FT-IR, Raman spectroscopy, and Zn concentration) and microstructural (SEM) properties of the different seeds were firstly evaluated to establish differences between the studied cultivars. In addition, the use of controlled-release soybean protein-based matrices without zinc (M) or with zinc incorporated (MZ) was evaluated as fertilizers in the different barley cultivars. In this sense, the use of these matrices as a zinc carrier improved seed germination and zinc content in the plants, indicating that the use of matrices improves the amount of zinc assimilated by the crops (up to 30 and 50% with M and MZ, respectively) and allows the proper root growth of all cultivars of barley. In conclusion, this article shows the potential of controlled-release protein-based matrices as substitutes for conventional fertilization.

Abstract To reduce agriculture's carbon, land and water footprint, the diffusion of conservation farming methods is one commonly cited proposition. Yet the process of translating available information on new conservation farming methods into farmers' practices is often a black box in many studies. This understanding is critical to inform strategies for scaling these complex, knowledge-intensive, but necessary practices for improving agriculture's resource and climate balance sheet. By implementing a series of mediation analysis using data from 700 households in Malawi and 930 households in Tanzania, this study examines how an improved understanding of conservation agriculture (CA) principles is an important mediator in the pathway from extension contact to the adoption of two of the CA practices examined. For the adoption of conservation tillage, the share of the mediated treatment effect was in the 31.5–34.4% range, while it was 31.6–46.9% for the adoption of soil cover (mulching). Our results suggest that unless learning from external sources strongly correlates with improved farmers' technical understanding of new farming practices, private learning by doing must be a critical adjunct to other avenues of learning. Beyond the basic promotional goals, improving farmers' technical know-how needs to be the centerpiece of holistic efforts in support of conservation farming and similar knowledge-intensive practices necessary for agriculture's sustinability goals.

Abstract Food loss and waste throughout the food supply chain is a growing issue with significant economic, social and environmental implications. Wasted food represents lost profits for the food industry, increased food insecurity in communities and the unnecessary production of greenhouse gas emissions, among many other detrimental consequences. Due to the large number of stakeholders involved in the food supply chain and the complexity of their relationships, there is increasing interest in addressing food waste issues through collaborative governance approaches, such as food policy councils (FPCs). Assessing how FPCs engage diverse stakeholders and organizations in food waste reduction efforts can provide important lessons for improving local food systems governance more broadly and contribute to the creation of more sustainable food systems. To do this, we leverage the theoretical concept of ‘collaborative advantage’ to analyze how FPCs foster collaboration, both internally and with external partners, to achieve policy and programmatic goals that individual stakeholders could not achieve alone. Drawing on plan documents and semi-structured interviews with members of five FPCs across the USA, we find that FPCs can foster collaborative advantage by establishing comprehensive food system plans, systematically measuring progress toward objectives, and transparently communicating the evidence of their progress to the communities they serve.

Abstract This study evaluated the agro-environmental and economic effectiveness of strips introduced in a diversified organic vegetable system. Two experiments of three experimental years (2018, 2019, 2020) were carried out within the 4-year rotation of MOnsampolo VEgetable organic Long-Term Experiment (MOVE LTE) in Central Italy to test strip cropping vs pure stand. The crop combinations in the two experiments were faba bean (Vicia faba L.)–tomato (Solanum Lycopersicum L.) and common wheat (Triticum aestivum)–zucchini (Cucurbita pepo L.). We determined the productive and economic performances, disease and weed control, nutritional differences and effectiveness in returning carbon to the soil. The two strip cropping systems allowed a better use of resources, enhancing plant biomass and crop residues, particularly for tomato (+24%) and zucchini (+63%). However, the greater plant biomass did not always result in an increase in crop yields. For example, while the wheat–zucchini strip system showed a land equivalent ratio >1 in all three experimental years with a high yield performance in zucchini (+54% of yield), the faba bean–tomato system was more productive in strips only in 2018. On the contrary, this latter system contributed a carbon return >1 in all three experimental years. No significant differences between strip and pure stand systems were observed for fusarium (Fusarium oxysporum f. sp. lycopersici) and oidium (Oidium spp.) diseases on tomato and zucchini crops, respectively, and for weed control. Lastly, greater labor costs associated in both experiments did not affect their profitability (+21% and +319% in faba bean–tomato and wheat–zucchini experiments, respectively). Overall, our findings pointed out that farmers could increase sustainability of their cropping systems with the introduction of a well-designed strip cropping system, which can lead to the reduction of economic risks, greater potential soil carbon and more efficient use of resources on the same land.
摘要本研究评价了在多样化有机蔬菜体系中引入条带的农业环境效益和经济效益。在意大利中部MOnsampolo蔬菜有机长期试验(MOVE LTE)的4年轮作中，进行了三个试验年(2018年、2019年、2020年)的两个试验，以测试带状种植与纯林分种植的对比。两个试验的作物组合为蚕豆(Vicia faba L.) -番茄(Solanum Lycopersicum L.)和小麦(Triticum aestivum) -西葫芦(Cucurbita pepo L.)。我们确定了生产和经济性能、疾病和杂草控制、营养差异和向土壤返回碳的有效性。两种带状种植制度可以更好地利用资源，提高植物生物量和作物残茬，特别是番茄(+24%)和西葫芦(+63%)。然而，更大的植物生物量并不总是导致作物产量的增加。例如，小麦-西葫芦带状种植体系在所有三个试验年份均显示出土地当量比bbbb1，西葫芦产量较高(+产量的54%)，而蚕豆-番茄带状种植体系仅在2018年产量更高。相反，后一种系统在所有三个实验年贡献了100亿美元的碳回报。番茄赤霉病(fusarium oxysporum f. sp. lycopersici)和西葫芦赤霉病(oidium spp. oidium spp.)的防治效果与纯林分系统间无显著差异。最后，两项试验中较高的劳动力成本并未影响其盈利能力(蚕豆-番茄和小麦-西葫芦试验分别为+21%和+319%)。总体而言，我们的研究结果指出，农民可以通过引入设计良好的带状种植制度来提高其种植制度的可持续性，这可以降低经济风险，增加潜在的土壤碳，并更有效地利用同一土地上的资源。

Abstract Urban community gardens promote human health, offer recreational space and support urban biodiversity. Urban gardens are situated in diverse landscape contexts and have diverse social contexts with gardeners of various horticultural experiences and backgrounds, both of which results in the wide plant species variety of urban garden habitats. These plants represent a range of traits, one of which may be the production of substances that are poisonous to humans. These plants may also be of ecosystem functioning and biodiversity conservation value, creating an ecosystem service trade-off of human health promotion. In this paper, we report on the occurrence of poisonous plant species in 30 urban community gardens in two German cities (Berlin, Munich) and discuss potential concerns around poisonous and highly poisonous plants in urban gardens. We conclude that, depending on the garden participants as well as the goals of the garden organization, poisonous plants should be carefully monitored and managed to dually mitigate health risks while supporting biodiversity conservation. We propose possible strategies to manage potential threats posed by these plants while simultaneously allowing them to reside alongside people in urban gardens.

Abstract As organic food increases in popularity, there has been increased interest in the history of organic farming. Previous scholarship has done excellent work documenting the social and political aspects of organic and sustainable agriculture, but less research has been done on the history of organic farming methods. The purpose of this study was to address this deficiency by surveying the organic and sustainable farming community in the midwestern and northeastern United States to identify influential authors, publications and organizations. Information about influences on farming practices was created using an anonymous online survey, distributed through organic and sustainable agriculture organizations in the target region. Out of the 224 respondents who completed the survey, 171 (76%) listed books, 169 (75%) listed organizations and 123 (55%) listed influential individuals. A total of 218 authors were identified, with Eliot Coleman receiving the most mentions, followed by Rodale publications, Wendell Berry, Acres U.S.A. magazine, Masanobu Fukuoka, Joel Salatin and Michael Pollan. 242 organizations were listed, with Marbleseed (MOSES), MOFGA, NOFA, PASA, OEFFA, LSP, SFA-MN and MOFFA most frequently mentioned. These results provide a useful starting point for future research on the development and dissemination of farming methods in this region. Research priorities include conducting oral histories with still-living authors of influential books and archiving organizational records before critical historical information is lost.

Abstract Farmers and food entrepreneurs are encouraged to enter direct and intermediated markets for value-added food products, but do not have information that they need to determine whether the markets are financially feasible for their operations. We conduct timed trials in a state-of-the-art regional shared-use food processing facility in the Northeast, and test production costs for two high-quality, safe, value-added frozen products: blueberries and spinach. We combine this with research on capital costs, field research on distribution costs and baseline per-unit revenues, and published research on potential market returns, and assess the conditions under which frozen produce sales can be a good business choice for farmers and food businesses in local and regional food markets. We develop a roadmap and a calculator tool that potential market entrants, extension agents, regional food business centers and other agricultural support providers can modify to reflect local and regional market conditions. The tool can help determine whether entering the frozen produce market is a good fit for a farm or food business. In general, we find that frozen regional blueberries have potential to generate a profitable return for medium-scale farmers with access to a shared-use facility, or farmer aggregators with the ability to invest in their own facilities. Frozen regional spinach is unlikely to generate a profitable return at the regional scale. Our results provide critical information to policy makers regarding the scale of production necessary to justify investments in regional shared-used kitchens. Results also suggest that policy makers should be cautious when encouraging farmers and food businesses to enter value-added markets, as there is significant potential for these markets to under-perform.

Abstract Pollinators are a crucial group of organisms due to their role in the maintenance of environmental biodiversity and crop production. Pollinators may be very diverse; however, in temperate areas they are mainly insects, and the most active and important are certainly the bees. Not only the well-known honeybee: there are almost 2000 species of wild bees in Europe, and about 1000 just in Italy. There is an increasing public worry related to their decline and to the impact that this decline may have on agricultural production. The way public perception of the pollinator issue arises is generally neglected, especially by important stakeholders such as the farmers. Moreover, direct actions were not indicated by the policy till recently. We surveyed the main steps that possibly drove the current political perspective at the European and national (Italian) level. We found an increased boost toward healthier environments through the release of various documents. To look for changes that may include pollinator protection, we need to address the Common Agricultural Policies (CAPs), the tool that shapes the European agro-environments. A new CAP document has been recently released, and the Member States are moving toward the definition of eco-schemes to be adopted by farmers after payments. Italy placed pollinators in pole position with a dedicated eco-scheme: will pollinators finally be acknowledged?
