Legume-rice rotations increase rice yields and carbon sequestration potential globally
Rice feeds half of the world's population but faces the pressures of yield demand under increasing environmental and climate pressures. Diversified cropping systems such as legume-based rotations may be a viable solution, but rice yield responses and environmental implications have not been synthesized globally. Here, based on 1,483 data pairs covering 17 major rice production countries worldwide, we revealed that legume inclusion increased subse…
Quantification and comparison of subnational and national agricultural nitrogen flows in Denmark and Sweden
Ensuring food production with low nitrogen (N) environmental emissions requires good quantitative knowledge of N flows in agricultural systems to monitor emissions and N use efficiency (NUE, the ratio of N outputs to inputs). Our study quantifies the main N agricultural flows at subnational and national scales in Denmark and Sweden from 2011 to 2020, calculating the NUE for crop and livestock production and associated nitrous oxide (N 2 O) and am…
From field measurements to national inventories and smart incentives—the SmartField approach for agricultural soil N 2 O fluxes
Significantly reducing greenhouse gas (GHG) emissions from agricultural production is crucial to limiting climate change. Fertilized soils are a major source of nitrous oxide (N 2 O), a potent GHG. Reducing N 2 O emissions is a key interest for many countries, including Denmark, where approximately 90% of N 2 O emissions originate from agricultural soils. Although the link between nitrogen (N) fertilization and N 2 O emissions is well-known, quan…
Optimize farm size and agronomic practices to improve agricultural sustainability
Synthesizing the evidence of nitrous oxide mitigation practices in agroecosystems
Nitrous oxide (N 2 O) emissions from agricultural soils are the main source of atmospheric N 2 O, a potent greenhouse gas and key ozone-depleting substance. Several agricultural practices with potential to mitigate N 2 O emissions have been tested worldwide. However, to guide policymaking for reducing N 2 O emissions from agricultural soils, it is necessary to better understand the overall performance and variability of mitigation practices and i…
Evidence for increasing global wheat yield potential
Wheat is the most widely grown food crop, with 761 Mt produced globally in 2020. To meet the expected grain demand by mid-century, wheat breeding strategies must continue to improve upon yield-advancing physiological traits, regardless of climate change impacts. Here, the best performing doubled haploid (DH) crosses with an increased canopy photosynthesis from wheat field experiments in the literature were extrapolated to the global scale with a …
Methodology to assess the changing risk of yield failure due to heat and drought stress under climate change
While the understanding of average impacts of climate change on crop yields is improving, few assessments have quantified expected impacts on yield distributions and the risk of yield failures. Here we present the relative distribution as a method to assess how the risk of yield failure due to heat and drought stress (measured in terms of return period between yields falling 15% below previous five year Olympic average yield) responds to changes …
Land-use and agriculture in Denmark around year 1900 and the quest for EU Water Framework Directive reference conditions in coastal waters
The EU Water Framework Directive (WFD) aims to protect the ecological status of coastal waters. To establish acceptable boundaries between good and moderate ecological status, the WFD calls for reference conditions practically undisturbed by human impact. For Denmark, the nitrogen (N) concentrations present around year 1900 have been suggested to represent reference conditions. As the N load of coastal waters relates closely to runoff from land, …
Nitrate leaching losses from two Baltic Sea catchments under scenarios of changes in land use, land management and climate
Pollution with excess nutrients deteriorate the water quality of the Baltic Sea. The effect of combined land use and climate scenarios on nitrate leaching and nitrogen (N) loads to surface waters from two Baltic Sea catchments (Norsminde in Denmark and Kocinka in Poland) was explored using different models; the NLES and Daisy models for nitrate leaching, and MIKE SHE or MODFLOW/MT3DMS for N transport. Three Shared Socioeconomic Pathways (SSP1, SS…
Spatially differentiated regulation
The Baltic Sea Action Plan and the EU Water Framework Directive both require substantial additional reductions of nutrient loads (N and P) to the marine environment. Focusing on nitrogen, we present a widely applicable concept for spatially differentiated regulation, exploiting the large spatial variations in the natural removal of nitrate in groundwater and surface water. By targeting mitigation measures towards areas where nature’s own capacity…
Future socioeconomic conditions may have a larger impact than climate change on nutrient loads to the Baltic Sea
The Baltic Sea is suffering from eutrophication caused by nutrient discharges from land to sea, and these loads might change in a changing climate. We show that the impact from climate change by mid-century is probably less than the direct impact of changing socioeconomic factors such as land use, agricultural practices, atmospheric deposition, and wastewater emissions. We compare results from dynamic modelling of nutrient loads to the Baltic Sea…
Possibilities for near-term bioenergy production and GHG-mitigation through sustainable intensification of agriculture and forestry in Denmark
To mitigate climate change it is necessary to further increase the deployment of renewable energy, including bioenergy. This analysis shows how this can be achieved in Danish agriculture and forestry before 2020. The key is a sustainable intensification and we show through three scenarios how it is possible to increase production while at the same time decreasing environmental impact and with only minor consequences on food and feed production. A…
Spatial Variation of Temperature and Precipitation in Bhutan and Links to Vegetation and Land Cover
Bhutan, located in the Himalayas in the South Asian monsoon region, has extremely high variation in elevation, climatic conditions, and land cover despite its small geographical area, as well as great biodiversity. This paper provides the first comprehensive description of climatic conditions in Bhutan. It assesses the spatial variation of temperature and precipitation across the country and evaluates the causes for this variation based on daily …
Knowledge Asymmetries Between Research and Practice
This article discusses the problem of implementing scientific knowledge in practice. The discussion is based on a case study of barriers to implementing research-based principles of sustainable organic arable farming. The current literature tends to see this problem either as a dissemination issue (the linear approach) or as a failure of science to address real-world problems (the co-constructive approach). We argue that Luhmann's theory of socia…
Policies for agricultural nitrogen management—trends, challenges and prospects for improved efficiency in Denmark
With more than 60% of the land farmed, with vulnerable freshwater and marine environments, and with one of the most intensive, export-oriented livestock sectors in the world, the nitrogen (N) pollution pressure from Danish agriculture is severe. Consequently, a series of policy action plans have been implemented since the mid 1980s with significant effects on the surplus, efficiency and environmental loadings of N. This paper reviews the policies…
