Modelling the economics of agroforestry at field- and farm-scale
This report (Deliverable 6.18) assesses the economics of agroforestry systems at field- and farm-scales and compares them with alternative land uses such as arable cropping, pasture and forestry. This analysis is undertaken in terms of financial profitability (e.g. from a farmer perspective) and economic benefits (e.g. from a societal perspective)N/
Quantifying regulating ecosystem services with increased tree densities on European Farmland
Agroforestry systems have been compared to agricultural and forestry alternatives, providing a land-use solution for additional environmental benefits while maintaining similar levels of productivity. However, there is scarce research assessing such patterns across a pan-European scale using a common methodology. This study aims to improve our understanding of the role of trees in three different regulating ecosystem servicesâ(1) soil erosion, (2) nitrate leaching and (3) carbon sequestrationâin traditional and innovative agroforestry systems in Europe through a consistent modeling approach. The systemsâ assessment spans environmentally from the Mediterranean environmental region in Portugal to the Continental environmental region in Switzerland and Germany to the Atlantic environmental region in the United Kingdom. Modeled tree densities were compared in the different land-use alternatives, ranging from zero (agriculture with only crops or pasture) to forestry (only trees). The methodology included the use of a biophysical model (Yield-SAFE) where the quantification of the environmental benefits was integrated. Results show a consistent improvement of regulating ecosystem services can be expected when introducing trees in the farming landscapes in different environmental regions in Europe. For all the systems, the forestry alternatives presented the best results in terms of a decrease in soil erosion of 51% (±29), a decrease of nearly all the nitrate leaching (98% ± 1) and an increase in the carbon sequestration of up to 238 Mg C haâ1 (±140). However, these alternatives are limited in the variety of food, energy and/or materials provided. On the other hand, from an arable or pure-pasture alternative starting point, an increase in agroforestry tree density could also be associated with a decrease in soil erosion of up to 25% (±17), a decrease in nitrates leached of up to 52% (±34) and an increase in the carbon sequestered of 163 Mg C haâ1 (±128) while at the same time ensuring the same levels of biomass growth and an increase in product diversification.We acknowledge the financial support provided by the Portuguese Foundation for Science and Technology (FCT) through the scholarship (SFRH/BD/52691/2014) and the European Community's Seventh Framework Programme under Grant Agreement No. 613520 (Project AGFORWARD).

Towards the coordinated and fit-for-purpose deployment of Unmanned Aerial Systems (UASs) for flood risk management in England
This is the final version. Available on open access from IWA Publishing via the DOI in this recordData availability statement:
Data cannot be made publicly available; readers should contact the corresponding author for details.Preparedness for flood emergency response is crucial for effective flood management. The need for advanced flood decision support tools that aid flood management has been recognized by several authors. This work examines the variability that currently exists across England with regard to the Unmanned Aerial System (UAS) data collection and processing strategy in flood emergency events. Expert elicitation was carried out using a tailored questionnaire about UAS deployment in three flood emergency scenarios. The survey highlighted that reduced equipment assembly time, a national network of appropriately qualified UAS pilots and the effective UAS deployment when on-site, can reduce the response time to flood emergency. For improved comparability and reduced bias in data collection and interpretation, clear guidelines on which data products are most beneficial for particular purposes, processing time required, platform and sensor selection may also be necessary. We consider that releasing a comprehensive documentation pack, which includes guidelines, standards and protocols that detail the methods, tools, technology, quantity and quality of data, to UAS pilots on a flood emergency call, will enhance the timely response.Engineering and Physical Sciences Research Council (EPSRC
Modelling the Interactions of Soils, Climate, and Management for Grass Production in England and Wales
This study examines the effectiveness of a model called LINGRA-N-Plus to simulate the interaction of climate, soil and management on the green leaf and total dry matter yields of ryegrass in England and Wales. The LINGRA-N-Plus model includes modifications of the LINGRA-N model such as temperature- and moisture-dependent soil nitrogen mineralization and differential partitioning to leaves and stems with thermal time from the last harvest. The resulting model was calibrated against the green leaf and total grass yields from a harvest interval x nitrogen application experiment described by Wilman et al. (1976). When the LINGRA-N-Plus model was validated against total grass yields from nitrogen experiments at ten sites described by Morrison et al. (1980), its modelling efficiency improved greatly compared to the original LINGRA-N. High predicted yields, at zero nitrogen application, were related to soils with a high initial nitrogen content. The lowest predicted yields occurred at sites with low rainfall and shallow rooting depth; mitigating the effect of drought at such sites increased yields by up to 4 t haâ1. The results highlight the usefulness of grass models, such as LINGRA-N-Plus, to explore the combined effects of climate, soil, and management, like nitrogen application, and harvest intervals on grass productivity
AGFORWARD Project Final Report
Executive summary:
The AGFORWARD project (Grant Agreement N° 613520) had the overall goal to promote
agroforestry practices in Europe that will advance sustainable rural development. It had four
objectives (described below) which address 1) the context and extent of agroforestry in Europe, 2)
identifying, developing and field-testing agroforestry innovations through participatory networks,
3) evaluating innovative designs and practices at field-, farm-, and landscape-scales, and promoting
agroforestry in Europe through policy development and dissemination. Agroforestry is defined as
the practice of deliberately integrating woody vegetation (trees or shrubs) with crop and/or animal
systems to benefit from the resulting ecological and economic interactions.
Context: European agroforestry has been estimated to cover 10.6 Mha (using a literature review)
and 15.4 Mha using the pan-European LUCAS dataset (i.e. 8.8% of the utilised agricultural area).
Livestock agroforestry (15.1 Mha) is, by far, the dominant type of agroforestry. The LUCAS analysis
provides a uniform method to compare agroforestry areas between countries and over time.
Identify, develop and field-test agroforestry innovations: 40 stakeholder groups (involving about
820 stakeholders across 13 European countries) developed and field-tested agroforestry innovations
which have been reported in 40 âlesson learntâ reports, and in a user-friendly format in 46
âAgroforestry innovation leafletsâ. The innovations for agroforestry systems of high nature and
cultural value included cheaper methods of tree protection and guidance for establishing legumes in
wood pastures. Innovations for agroforestry with timber plantations, olive groves and apple
orchards include the use of medicinal plants and reduction of mowing costs. Innovations for
integrating trees on arable farms included assessments of yield benefits by providing wind
protection. Innovations for livestock farms included using trees to enhance animal welfare, shade
protection, and as a source of fodder. Peer-reviewed journal papers and conference presentations
on these and other related topics were developed.
Evaluation of agroforestry designs and practices at field- and landscape-scale: a range of publicly
available field-scale analysis tools are available on the AGFORWARD website. These include the
âCliPickâ climate database, and web-applications of the Farm-SAFE and Hi-sAFe model. The results
of field- and landscape-scale analysis, written up as peer-reviewed papers, highlight the benefits of
agroforestry (relative to agriculture) for biodiversity enhancement and providing regulating
ecosystem services, such as for climate and water regulation and purification.
Policy development and dissemination: detailed reviews of existing policy and recommendations
for future European agroforestry policy have been produced. The support provided is far wider than
the single specified agroforestry measures. The recommendations included the collation of existing
measures, and that agroforestry systems should not forfeit Pillar I payments. Opportunities for farmlevel
and landscape-level measures were also identified. The project results can be found on the
project website (www.agforward.eu), a Facebook account (www.facebook.com/AgforwardProject),
a Twitter account (https://twitter.com/AGFORWARD_EU), and a quarterly electronic newsletter
(http://www.agforward.eu/index.php/en/newsletters-1514.html). The number of national
associations in Europe was extended to twelve, and a web-based training resource on agroforestry
(http://train.agforward.eu/language/en/agforall/) created. AGFORWARD also supported the Third
European Agroforestry Conference in Montpellier in 2016 attracting 287 delegates from 26 countries
including many farmers. We also initiated another 21 national conferences or conference sessions
on agroforestry, made about 240 oral presentations, 61 poster presentations, produced about 50
news articles, and supported about 87 workshop, training or field-visit activities (in addition to the
stakeholder groups)
AGFORWARD Third Periodic Report: July 2016 to December 2017
Project context
The European Union has targets to improve the competitiveness of European agriculture and
forestry, whilst improving the environment and the quality of rural life. At the same time there is a
need to improve our resilience to climate change and to enhance biodiversity. During the twentieth
century, large productivity advances were made by managing agriculture and forestry as separate
practices, but often at a high environmental cost. In order to address landscape-scale issues such as
biodiversity and water quality, we argue that farmers and society will benefit from considering landuse
as a continuum including both agriculture and trees, and that there are significant opportunities
for European farmers and society to benefit from a closer integration of trees with agriculture.
Agroforestry is the practice of deliberately integrating woody vegetation (trees or shrubs) with crop
and/or animal systems to benefit from the resulting ecological and economic interactions.AGFORWARD (Grant Agreement N° 613520) is co-funded by the European
Commission, Directorate General for Research & Innovation, within the 7th

Translating and applying a simulation model to enhance understanding of grassland management
Each new generation of grassland managers could benefit from an improved understanding of how modification of nitrogen application and harvest dates in response to different weather and soil conditions will affect grass yields and quality. The purpose of this study was to develop a freely available grass yield simulation model, validated for England and Wales, and to examine its strengths and weaknesses as a teaching tool for improving grass management. The model, called LINGRA-N-Plus, was implemented in a Microsoft Excel spreadsheet and iteratively evaluated by students and practitioners (farmers, consultants, and researchers) in a series of workshops across the UK over 2âyears. The iterative feedback led to the addition of new algorithms, an improved user interface, and the development of a teaching guide. The students and practitioners identified the ease of use and the capacity to understand, visualize and evaluate how decisions, such as variation of cutting intervals, affect grass yields as strengths of the model. We propose that an effective teaching tool must achieve an appropriate balance between being sufficiently detailed to demonstrate the major relationships (e.g., the effect of nitrogen on grass yields) whilst not becoming so complex that the relationships become incomprehensible. We observed that improving the user-interface allowed us to extend the scope of the model without reducing the level of comprehension. The students appeared to be interested in the explanatory nature of the model whilst the practitioners were more interested in the application of a validated model to enhance their decision making
