Abstract Europe imports large amounts of soybean that are predominantly used for livestock feed, mainly sourced from Brazil, USA and Argentina. In addition, the demand GM-free human consumption is project to increase. Soybean has higher protein quality digestibility than other legumes, along with high concentrations isoflavones, phytosterols minerals enhance nutritional value as a food ingredient. Here, we examine potential increase production across feed direct consumption, review possible...
The global land system is facing unprecedented pressures from growing human populations and climatic change. Understanding the effects these may have necessary to designing management strategies that ensure food security, ecosystem service provision successful climate mitigation adaptation. However, number of complex, interacting involved makes any complete understanding very difficult achieve. Nevertheless, recent development integrated modelling frameworks allows for exploration...
Phosphorus (P) is a key limiting factor in crop growth and essential for agriculture. As plant uptake of P inefficient, it commonly applied to maintain yields leading range negative environmental issues when excess. Additionally, mineral fertilisers derived from mined rock phosphate, which finite resource that needs be sustainably managed order food security the long-term. Phosphatase activity one several mechanistic responses deficiency plant-soil system, enabling mineralization organic...
Abstract Globally pervasive increases in atmospheric CO 2 and nitrogen (N) deposition could have substantial effects on plant communities, either directly or mediated by their interactions with soil nutrient limitation. While the direct consequences of N enrichment communities are well documented, potential rising globally widespread phosphorus (P) limitation remain poorly understood. We investigated simultaneous elevated (eCO ) P additions grassland biodiversity, community functional...
The combined indirect and direct impacts of land use change climate on river water quality were assessed. A allocation model was used to evaluate the response catchment long-term climatic changes. Its results drive a assess impact alterations freshwater nitrate phosphorus concentrations. Climatic projections employed estimate likelihood such response. River Thames (UK) as case-study. If is considered static parameter, according results, alone should reduce average concentration, although...
Abstract The importance of soils to society has gained increasing recognition over the past decade, with potential contribute most United Nations’ Sustainable Development Goals (SDGs). With unprecedented and growing demands for food, water energy, there is an urgent need a global effort address challenges climate change land degradation, whilst protecting soil as natural resource. In this paper, we identify contribution science decade addressing gaps in our knowledge regarding major...
Responses to future changes in climatic and socio-economic conditions can be expected vary between sectors regions, reflecting differential sensitivity these highly uncertain factors. A analysis was conducted using a suite of impact models (for health, agriculture, biodiversity, land use, floods forestry) across Europe with respect key climate variables. Depending on the indicators, aggregated grid or indicative site results are reported for eight rectangular sub-regions that together span...
Understanding how agricultural practices alter biogeochemical cycles is vital for maintaining land productivity, food security, and other ecosystem services such as carbon sequestration. However, these are complex, highly coupled long-term processes that difficult to observe or explore through empirical science alone. Models required capture the main anthropogenic disturbances, whilst operating across regions long timescales, simulating both natural environments, shifts among these. Many...
Long-term urban heat island (UHI) observations are uncommon and where available, generally unable to distinguish changing climate drivers from expansion; neither driver is treated independently.We overcome this limitation using a generalized additive model learn the variability in UHI intensity (UHII) at central London weather station (St James's Park) over 10-year observation period (2010)(2011)(2012)(2013)(2014)(2015)(2016)(2017)(2018)(2019).We then use reconstruct 70 years of monthly...
Abstract Bank erosion can contribute a significant portion of the sediment budget within temperate catchments, yet few catchment scale models include an explicit representation bank processes. Furthermore, is often simplistic resulting in inability to capture realistic spatial and temporal variability simulated erosion. In this study, component model SHETRAN developed incorporate key factors influencing spatio‐temporal rate erosion, due effects channel sinuosity vegetation. The applied Eden...
Channel bank erosion processes are controlled by numerous factors and as such both temporally spatially variable. The significance of channel to the sediment budget is difficult quantify without extensive fieldwork/data analysis. In this study, importance key physical controlling erosion, including slope, upstream catchment area, confinement, sinuosity, was explored using regression resulting analysis can be used in practical studies provide a first approximation rates (in catchments similar...
Abstract Natural Flood Management (NFM) techniques aim to reduce downstream flooding by storing and slowing the flow of stormwater river channels. These include a range measures, including setback outfalls physical restoration channels floodplains, improve natural functioning catchments. An additional benefit NFM measures is potential reduction in sediment pollutant delivery channel. Urban development releases variety heavy metal nutrient pollutants that enter rivers through with adverse...
Carbon stores in the terrestrial biosphere globally represent over 50 % of present-day organic carbon reservoirs and have significantly altered last three centuries owing to anthropogenic disturbances. Conversion natural land agricultural uses often results a loss soil carbon, whilst atmospheric deposition pollutants such as nitrogen has increased storage both biomass. Terrestrial underpins range ecosystem services, including climate regulation, food production, water services. This is...
Abstract. Ecosystems limited in phosphorous (P) are widespread, yet there is understanding of how these ecosystems may respond to anthropogenic deposition nitrogen (N) and the interconnected effects on biogeochemical cycling carbon (C), N, P. Here, we investigate consequences enhanced N addition for C–N–P pools two P-limited grasslands, one acidic limestone, occurring contrasting soils, explore their responses a long-term nutrient-manipulation experiment. We do this by combining data with an...
Abstract Carbon sequestration (C seq ) in soils and plant biomass is viewed as an important means of mitigating climate change. Recent global assessments have estimated considerable potential for terrestrial C , but generally lack sensitivity to warming, nutrient limitations perspective on local land use. These are factors since higher temperatures can accelerate the decomposition soil organic matter, availability affects productivity, while use pressures put broader constraints matter...
Riparian zones are critical interfaces to freshwater systems, acting as gateways for the conveyance and modification of macronutrient fluxes from land rivers oceans. In this paper, we propose that certain riparian conditions processes (conceptually ‘Riparian Reactive Interfaces’) may be susceptible environmental change with consequences accelerating local nutrient cycling cascading global impacts on cycles carbon (C), nitrogen (N), phosphorus (P). However, argue concept is insufficiently...
As a result of growing food demands, the area land used globally for agriculture has rapidly increased over last 300 years. Clearance natural vegetation and conversion to is often associated with terrestrial carbon loss, from both soil stores. Changes in storage implications production, climate water regulation. Quantifying these changes therefore vital understand risks resilience benefits. Land use East England significantly changed during this period now predominantly agriculture,...
Abstract. In many temperate ecosystems, nitrogen (N) limits productivity, meaning anthropogenic N deposition can stimulate plant growth and subsequently carbon (C) sequestration. Phosphorus (P) N-P co-limited grasslands are widespread, yet there is limited understanding of their responses to deposition, which may transition more ecosystems toward P-limited or states. Here, we investigate the consequences enhanced addition on C-N-P pools in different states nutrient limitation. We explored...
