“…The corn typically provides support for the climbing beans. The beans simultaneously enrich the soil in nitrogen through their association with nitrogen-fixing rhizobacteria, and the squash or pumpkins inhibit the growth of weeds and maintain soil moisture by generating a ground cover [25].…”

Rotating crops is a sustainable agricultural technique that has been at the disposal of humanity since time immemorial. Switching between cover crops and cash crops allows the fields avoids overexploitation due to intensive farming. How often the respite is to be provided and what is the optimum cash cover rotation in terms of maximising yield schedule is a long-standing question tackled on multiple fronts by agricultural scientists, economists, biologists and computer scientists, to name a few. Dealing with the uncertainty in the field due to diseases, pests, droughts, floods, and impending effects of climate change, is important to consider when designing the cropping strategy. Analysing this time-tested technique of crop rotations with a new lens of Parrondo's paradox allows us to improve upon the technique and use it in synchronisation with the burning questions of contemporary times. By calculating optimum switching probabilities in a randomised cropping sequence, suggesting the optimum deterministic sequences and judicious use of fertilisers, we propose methods for improving crop yield and the eventual profit margins for farmers. Overall we also extend the domain of applicability of the seemingly unintuitive paradox by Parrondo, where two losing situations can be combined eventually into a winning scenario.

“…• Using polyculture systems in contaminated soils has the potential to improve the efficiency of Cu phytoremediation processes. eases or enriching soils, thereby contributing to improved crop yields (Crews et al, 2018;Iverson et al, 2014;Ngapo et al, 2021). However, as urban agriculture gains traction in cities plagued by an industrial past, involved residents become more aware of the situation and raise legitimate concerns about soil contamination exceeding local guidelines for open-field cultivation, a phenomenon that may ultimately contribute to the failure of community food production enterprises (Beausoleil, 2010;Laidlaw et al, 2018;Lewis & Rosales, 2020;Peters et al, 2023;Wortman & Lovell, 2013).…”

Urban planners are increasingly focused on integrating urban farming as a creative strategy for producing sustainable, local food in underutilized spaces, once occupied by polluting industries, in peri‐urban areas. However, before urban farming's contribution to local self‐sufficiency can be determined, it is crucial to gather quantitative data on the effectiveness of tailored strategies, including polyculture, and the suitability of different vegetables, to adequately assess the value of brownfields. This study aims to provide quantitative agronomic data on a copper‐contaminated urban garden with the dual objective of assessing its capacity for food production and mitigating the spread of soil contamination. Tomato (Solanum lycopersicum) plants were grown for one growing season in brownfield soils with different copper concentrations (up to 2000 mg kg−1), accompanied by different plant species assemblages typically used in phytoremediation (Achillea millefolium, Salix discolor, and Trifolium repens). The most successful assemblage yielded over 800 fruits per square meter with low copper concentrations (<5 mg kg−1), indicating that one square meter could satisfy the annual fresh tomato weight requirement of an average individual. Although some amendments can improve adaptability to local soils, the highest fruit‐producing assemblage consisting of S. lycopersicum, S. discolor, and T. repens also proved to be the one of the most effective for copper phytoextraction, removing over 30 g ha−1 from the contaminated soils. Overall, the data indicated that all assemblages phytostabilized copper. The quantitative results of this study provide a valuable benchmark for urban planners and researchers to implement large‐scale urban agriculture on brownfield sites.

“…Evidence shows that some First Nation societies lived in agricultural settlements, cultivated land, and effectively farmed (Boyd et al, 2014;Carter, 2014). Here, research shows the historical and contemporary importance of companion planting the complementary crops of corn, beans, and squash-the "Three Sisters" (e.g., Bodirsky & Johnson, 2008;Ngapo et al, 2021;Norman, 2015).…”

This study explores diversity, equity and inclusion (DEI) policy texts in Canadian agriculture from a policy-as-information perspective. Public policy is a powerful form of information in shaping citizenship behaviour and identity. Borrowing theory from social constructionism and using “policy texts” as data, this article enables us to start to understand the discursive framework constructing under-represented groups in agriculture. The article finds that there is a patchwork quilt approach with DEI agricultural policy in Canada: Federal, provincial and territorial governments and non-governmental organizations are individually pursuing DEI agendas. The conclusion calls for future information research on DEI agricultural policy in Canada, with contributions from academics, practitioners, industry and farmers. The contribution of this article is twofold: It provides policy practitioners with a snapshot of current DEI policies in agriculture across Canada and it attempts to stimulate research and discussion among policy scholars through suggestions for future research.
