Agroecological practices in vineyards can enhance agroecosystems multifunctionality, by reducing pesticides use and their adverse effects on human health and the environment. However, growers remain concerned about potential negative impacts of plant diversification on grapevine performance, and existing literature report conflicting findings. This study employs both taxonomic and functional approaches to characterize weed communities in inter-rows of agroecological vineyards and assesses the effects of different plant diversification strategies-tillage (Tviti), service crop (Aviti), service crops and agroforestry (Dviti)- on soil quality, grapevine performance, and natural regulation processes over a two-year period in the south of France. Management practices shaped weed communities functional traits, with high tillage (Tviti) favoring acquisitive strategies plant communities. Those traits directly affected several of the indicators of services: service crops competed for soil resources, particularly nitrogen, affecting negatively grapevine yield and vigor. However, in 2023, more diverse systems (Aviti, Dviti) exhibited improved soil aggregate stability and increased natural enemy diversity. However, results varied significantly across years, highlighting the importance of environmental factors. Finally, no clear agroforestry effect was observed, likely due to the young age of the trees. A deeper understanding of the relationships between functional diversity and multiple ecosystem services in vineyards could help mitigate potential trade-offs associated with plant diversification. Furthermore, adapting management practices to local abiotic conditions and growers’ requirements is essential for optimizing both vineyard productivity and ecological sustainability.

Agriculture is an important source of greenhouse gases (GHG) globally. Unlike conventional practices which have contributed to declines in biodiversity, soil health and soil organic carbon, regenerative agriculture has the potential to mitigate and enhance resilience to climate change, support the restoration of soil health and biodiversity, among other advantages. Increasing plant diversity in grasslands has shown multiple environmental benefits, but similar studies in cereal crops are lacking. To study the impact of increased plant diversity on GHG and other agronomical parameters, zero to eight undersown species were intercropped with barley in southern Finland. GHG fluxes were measured with the chamber technique over two years alongside environmental parameters. Results showed higher CO uptake in barley with undersown species compared to barley monoculture during the shoulder seasons. In 2020–2021, based on gap-filled CO data and aboveground biomass, treatments with undersown species lost 42% less carbon than barley monoculture. Overall, CH and NO fluxes were small, and no differences were observed between treatments except in fall 2020. Soil temperature was modestly but significantly lower in barley with undersown species by 0.36 °C in summer 2020 while no differences were observed in soil moisture. There were no clear trends between one, four or eight undersown species, which suggest that adding one undersown species can already have an impact on CO fluxes, vegetation and soil parameters. Further studies are needed to more specifically assess how the different functional traits of the undersown species, such as rooting depth and nitrogen-fixing properties, impact GHG emissions.

Weed management is a key to the adoption of conservation agriculture practices in Sub-Saharan Africa. This study assessed the effect of conservation agriculture practices, strip-tillage and direct mulch-based cropping system on weed emergence, biomass and community structure in cotton-based cropping systems in northern Benin. The experiment was conducted in 2023 and 2024 using a randomized complete block design with three replications under three cropping systems: conventional tillage, strip tillage (cotton in biannual rotation with maize-cowpea intercropping over strip tillage) and direct mulch-based cropping system (cotton in three-season rotation with maize and Stylosanthes guianensis intercropping and sorghum and soybean intercropping over direct mulch-based cropping system). Weed emergence and species were inventoried at seven-day intervals starting from the first rainfall triggering their germination. Weed biomass was measured at each weeding. Conservation agriculture systems significantly reduced weed emergence compared to conventional tillage. The reductions were 15 % (cotton) and 46 % (maize) under strip tillage, and 33 % (cotton) and 56 % (maize) under direct mulch-based cropping system. Weed biomass increased significantly under the strip tillage system, i.e. by 40 % in cotton plots and by 41 % in maize plots. Crop yields were not significantly affected by systems. Weed community structure was shaped by the interaction between the cropping system and seasons, with distinct indicator species associated with cropping systems. These findings demonstrate that conservation agriculture practices can reduce weed emergence and alter weed community structure without compromising yield performance. This is the first study to characterize weed management under conservation agriculture in Sub-Saharan African cotton-based cropping systems.
