“…Fluctuating selection regimes play a crucial role in numerous fundamental and translational biological scenarios. The concept has been discussed before in dynamic cultivation strategies: ‘nomadic’ shifting cultivation and a high growth ‘colonial’ strategy [ 50 ]. The nomadic strategy resembles a cover crop game where one makes loss but improves the soil quality and the colonial strategy is akin to the cash crop game where one makes profit if the soil quality is good but that comes at the cost of depleting soil quality and hence, ultimately is a losing game.…”

Crop rotation, a sustainable agricultural technique, has been at humanity’s disposal since time immemorial and is practised globally. Switching between cover crops and cash crops helps avoid the adverse effects of intensive farming. Determining the optimum cash-cover rotation schedule for maximizing yield has been tackled on multiple fronts by agricultural scientists, economists, biologists and computer scientists, to name a few. However, considering the uncertainty due to diseases, pests, droughts, floods and impending effects of climate change is essential when designing rotation strategies. Analysing this time-tested technique of crop rotations with a new lens of Parrondo’s paradox allows us to optimally use the rotation technique in synchrony with uncertainty. While previous approaches are reactive to the diversity of crop types and environmental uncertainties, we make use of the said uncertainties to enhance crop rotation schedules. We calculate optimum switching probabilities in a randomized cropping sequence and suggest optimum deterministic sequences and judicious use of fertilizers. Our methods demonstrate strategies to enhance crop yield and the eventual profit margins for farmers. Conforming to translational biology, we extend Parrondo’s paradox, where two losing situations can be combined eventually into a winning scenario, to agriculture.

“…They showed that the survival-extinction boundary undergoes a novel transition of monotonicity in the way that for the nonmonotonic regime there is an optimal dispersal rate that maximizes the survival probability. Diffusion of populations can also relate to the emergence of Parrondo's paradox instances for which the combination of two losing (extinction) strategies -diffusion and inefficient α -combined yield a winning (preservation) situation [13,14,15].…”

We investigate the phenomenology emerging from a 2-species dynamics under the scenario of a quasi-neutral competition within a metapopulation framework. We employ stochastic and deterministic approaches, namely spatially-constrained individual-based Monte Carlo simulations and coupled mean-field ODEs. Our results show the multifold interplay between competition, birth-death dynamics and spatial constraints induces a nonmonotonic relation between the ecological majority-minority switching and the diffusion between patches. This means that diffusion can set off birthdeath ratios and enhance the preservation of a species. Keywords Competition • ecological dynamics • dispersal 1 IntroductionThe battle for resources plays a significant role in the dynamics of competitive ecosystems. For a long time, the outcome of such a dispute was directly associated with the set of birth/death ratios of the contending species, λ i /α i . However, that scenario has been chal-

Relieving Cost of Epidemic by Parrondo's Paradox: A COVID‐19 Case Study

COVID‐19, also known as SARS‐CoV‐2, is a coronavirus that is highly pathogenic and virulent. It spreads very quickly through close contact, and so in response to growing numbers of cases, many countries have imposed lockdown measures to slow its spread around the globe. The purpose of a lockdown is to reduce reproduction, that is, the number of people each confirmed case infects. Lockdown measures have worked to varying extents but they come with a massive price. Nearly every individual, community, business, and economy has been affected. In this paper, switching strategies that take into account the total “cost” borne by a community in response to COVID‐19 are proposed. The proposed cost function takes into account the health and well‐being of the population, as well as the economic impact due to the lockdown. The model allows for a comparative study to investigate the effectiveness of various COVID‐19 suppression strategies. It reveals that both the strategy to implement a lockdown and the strategy to maintain an open community are individually losing in terms of the total “cost” per day. However, switching between these two strategies in a certain manner can paradoxically lead to a winning outcome—a phenomenon attributed to Parrondo's paradox.
