As part of our HERBESREG project funded by Generalitat de Catalunya we keep sampling our experimental rice fields to assess how different water management practices shape weed communities and impact rice yield.

🕷️🌾 Looking forward to arrive Pontevedra to join @sibecol-aeet-25.bsky.social I'll talk Monday evening (19:15) in session TSB.8 about cascading effects of water-saving strategies in rice farming across the freshwater-terrestrial interface. Be there to know more!

Stay tunned if you want to know how these changes in freshwater biological communities translate in terms of multifuncionality provisioning (carbon sequestration potential, nutrient cycling, weed an pest control, food provisioning, etc). Next chapter of Seba's thesis.

BUT.... Abundance of larvae of aquatic bugs, dragonflies and damselflies, and specially tadpoles was remarkably reduced in AWD managed plots when compared to permanent flooded plots. Intermediate values were found for MSD-managed plots. Species diversity also declined at both AWD and MSD plots.

As expected methane emissions dropped sharply under water-saving irrigation.
– AWD reduced methane by 92.5%
– MSD by 67.3%
when compared to continuous flooding. This confirms strong mitigation potential associated to the drainage periods, which inhibits methanogenesis.

Specifically, we evaluated 3 irrigation practices that represents a gradient of water use:
* Traditional continuous flooding (CONV) – no drying periods during the growing season
* Mid-Season Drainage (MSD) – 1 drying period
* Alternate Wetting and Drying (AWD) – Multiple drying periods
* Traditional continuous flooding (CONV) – no drying periods during the growing season
* Mid-Season Drainage (MSD) – 1 drying period
* Alternate Wetting and Drying (AWD) – Multiple drying periods

In this study we performed a field-scale experiment in the Ebro Delta Experimental Research Station to evaluate potential trade-offs of mitigation strategies in terms of methane emissions and biodiversity outcomes (diversity/abundance of tadpoles, fishes & aquatic macroinvertebrates)

However, the potential negative impacts of these mitigation strategies on freshwater biodiversity associated to rice fields (e.g., amphibians, fishes, or aquatic macroinvertebrates) have been completely ignored until now. Foto: Antonio Camacho Lorenzo

Flooded rice farming is a major source of methane, but also an important complementary habitat to natural wetlands. To reduce the contribution of rice farming to climate change (CC hereafter), different water-saving irrigation practices are being promoted globally; even considered in carbon markets

Environmental policies quite often suffers from carbon tunnel vision—a narrow focus on reducing GHG emissions, but neglecting potential side effects on other agrienvironmental issues (e.g. biodiversity loss). Our new study highlights why this is a pervasive oversimplification in rice agroecosystems

We are specially interested in biological control of the rice water weevil (Lissorhoptrus oryzophilus), a recently introduced species in the Ebro Delta, which spend most of the day swimming in the water layer but climb to rice leaves for feeding.

11/11 In conclusion, our study highlights the multiple benefits of field margin restoration, but also the need to identify strategies that maximize multifunctionality while remaining economically feasible for farmers.

10/11 Overall, all restoration strategies promoted a relatively similar multifunctionality, when accounting for the economic cost of restoration actions, the spontaneous restoration emerged as the most cost-efficient strategy

9/11 Finally, restoration reduced the erosion of margin soil, especially in hedgerows which exhibited a more developed radicular system than flower strips or the passive restoration strategy.
