Ecological redesign of crop ecosystems for reliable crop protection. A review

Agronomy for Sustainable Development, Journal Year: 2024, Volume and Issue: 44(6)

Published: Oct. 23, 2024

Abstract To attain food security, we must minimize crop losses caused by weed growth, animal herbivores, and pathogens (or “pests”). Today, production depends heavily on the use of chemical pesticides “pesticides”) to protect crops. However, are phased out as they lose efficiency due pest resistance, few new appearing market. In addition, policies national action programs implemented with aim reducing pesticide risks. We redesign our cropping systems successfully crops against pests using fewer or no pesticides. this review, I focus principles for redesigning ecosystem. Ecological aims enhance ecological functions in order regulate populations diminish losses. Exploring ecology ecosystems plays an important role transition. Guiding system can be drawn from understanding its ecology. Ecosystem community ecologists have identified four principal characteristics that biotic regulation processes across ecosystems: (i) advanced ecosystem succession through introducing conserving perennial landscape habitats; (ii) reduced disturbance frequency intensity; (iii) increase both managed wild functional biological diversity, above below ground; (iv) matched spatial extent land (e.g., field size) dispersal capacity predators). review practices link these protection grain commodity agricultural landscape.

Precrop-treated soil influences wheat (Triticum aestivum L.) root system architecture and its response to drought

Frontiers in Plant Science, Journal Year: 2024, Volume and Issue: 15

Published: June 4, 2024

Aims Root system architecture (RSA) plays an important role in the plant’s ability to sustain yield under abiotic stresses such as drought. Preceding crops (precrops) can affect of proceeding crop, partially by affecting RSA. This experiment aims explore interactions between precrop identity, crop genotype and drought at early growth stages. Methods Rhizotrons, sized 60 × 80 3.5 cm, were used assess root two winter wheat (Triticum aestivum L.) genotypes, using precrop-treated soil around seedlings differing water regimes. The rhizotrons automatically imaged 3 times a week track development. Results Precrop-treated affected RSA changes caused reduced treatment (RWT) different depending on precrop. Largest these was 36% reduction depth after wheat, but 44% OSR. indicates that effects be simulated, least partially, transferring soils controlled environments. genotypes had differential reacted differently RWT, with Julius maintaining 8.8-13.1% deeper compared Brons RWT. In addition, combined environmental differently. Conclusion Our results could help explain discrepancies found from precrops enhance they indicate differences preceding effect when experiencing stress. Further, are genotypic interactions, which select adapt for specific rotations, year. Additionally, we have shown viable method stimulating partial seedling stage greenhouse setting field germinated seed.

Effectiveness of Options for the Adaptation of Crop Farming to Climate Change in a Country of the European South

Agriculture, Journal Year: 2024, Volume and Issue: 14(10), P. 1814 - 1814

Published: Oct. 15, 2024

This study quantitatively evaluates the effectiveness of three main options for adaptation crop farming to climate change (i.e., shift planting dates, increase/addition irrigation, and resilient hybrids/cultivars) in Greece, a country southern Europe. The potential effect each option on yields several crops all Greek regions is estimated 2021–2040 2041–2060 compared with those under historical local 1986–2005, by using agronomic statistical regression models, data from different climatic simulations scenarios. Our results reveal that examined have significantly reduce yield losses occurring no adaptation, particularly during when many more than half can be compensated for. Notably, some cases this period, measures resulted are higher climate. However, diminished very adverse conditions, highlighting dynamic nature adaptation. Assessing combined evaluating additional criteria (e.g., feasibility) represent essential areas future research.

Changes in the Yield Effect of the Preceding Crop in the US Corn Belt Under a Warming Climate

Global Change Biology, Journal Year: 2024, Volume and Issue: 30(11)

ABSTRACT Crop rotation has been widely used to enhance crop yields and mitigate adverse climate impacts. The existing research predominantly focuses on the impacts of under growing season (GS) climates, neglecting influences non‐GS (NGS) climates agroecosystems. This oversight limits our understanding comprehensive climatic and, consequently, ability devise effective adaptation strategies in response warming. In this study, we examine both GS NGS conditions yield effect preceding corn‐soybean systems from 1999 2018 US Midwest. Using causal forest analysis, estimate that increases corn soybean by 0.96 0.22 t/ha average, respectively. We then employ statistical models indicate increasing temperatures rainfall reduce benefits, while warming enhances benefits for soybeans. By 2051–2070, project will 6.74% Shared Socioeconomic Pathway (SSP) 1‐2.6 17.18% SSP 5‐8.5. For soybeans, are expected increase 8.36% 13.83% Despite these diverse crops, could still improve county‐average yields, as neither nor was fully rotated.

Crop impacts from compound weather extremes in major breadbaskets under climate change

Published: Dec. 14, 2024

Staple crops such as wheat, maize, and soybean are essential for global food security, yet they remain highly vulnerable to extreme weather events like heat waves, cold spells, droughts, excessive rainfall. The interplay between different stressors can amplify crop damage significantly. When multiple occur together, their combined impact on yields be far greater than individual alone. Misunderstanding these complex interactions risks underestimating how climate change could affect agricultural production. In recent decades, production has become concentrated in a few key breadbasket regions. Teleconnections the El Niño Southern Oscillation (ENSO) synchronize failures across regions, posing severe threats supply creating security trade-dependent areas. These adverse conditions lead compounding impacts time space.
