Consumers are increasingly focused on making sustainable food choices, necessitating transparent and trusted systems for providing sustainability information. This can be implemented, for instance, through application of traceability systems that “carry” sustainability information about production and distribution. Currently, the literature on trac...

Existing research on the social and cultural (S&C) values of treescapes tends to be limited in scope, for example to recreation, aesthetic or health values, and much is primarily qualitative, which provides rich detail but does not lend itself easily to incorporation into decision‐making. Having a way to quantify the range of S&C values associated...

We describe experiences between 2018 and 2021 co-designing tree health policy options linked with the UK’s evolving land use policy post EU-Exit within the Future Farming and Countryside Programme. Policy makers, researchers and more than 250 land managers took part in a series of co-design engagements in a three-phase iterative co-design process t...

Various food safety and environmental problems in China have raised consumer awareness of food safety issues and negative environmental impacts in various supply chains. This research assessed consumer preferences and willingness to pay (WTP) for food safety and ecosystem delivery attributes associated with apples, demonstrated through the applicat...

Early detection of pests at a low population prevalence is a key pillar of surveillance for plant health. A novel pest is expected to undergo exponential growth when it first occurs in a host population. This allows for the use of mathematical rules of thumb for the number of samples required to detect presence before it reaches a target prevalence...

The research aimed to understand farmers’ willingness to adopt (WTA) and willingness to pay (WTP) for precision pesticide technologies and analyzed the determinants of farmers’ decision-making. We used a two-stage approach to consider farmers’ WTA and WTP for precision pesticide technologies. A survey of 545 apple farmers was administered in Bohai...

Ensuring the reliability of diagnostic activities is an essential cornerstone of plant health strategies to reduce the risk of entry and spread of plant pests in a region and ultimately their impacts. Diagnostic tests should be validated to ensure that they are fit for purpose. Validation is usually done by diagnostic laboratories, although compani...

Innovation in environmental fields such as plant health is complex because of unbounded challenges and lack of certainty of commercial uptake. In this paper we present a Technology Readiness Level (TRL) framework, specifically to assist with assessment of technologies to support detection of tree pests and pathogens, but also for wider potential ad...

China is one of the largest apple-producing countries in the world, with large orchards and diverse climates. Accurately forecasting the first-flowering time of apple trees can assist orchard managers in their deciding when to apply anti-freeze. The temperature-driven sequential model from previous studies can be used to forecast the flowering phen...

Background Research into public risk perceptions associated with emerging risks in agriculture and supply chains has focused on technological risks, zoonotic diseases, and food integrity, but infrequently on naturally occurring diseases in plants. Plant virus infections account for global economic losses estimated at $30 billion annually and are re...

Precision agriculture (PA) technologies offer a potential solution to food security and environmental challenges but, will only be successful if adopted by farmers. Adoption in China lags behind that in some developed agricultural economies despite scientifically proven benefits of PA technologies for Chinese agriculture. Adoption is dependent on f...

Apple is one of the most important cash crops in China. However, negative economic, environmental and social impacts are associated with its production. This study aims to apply a holistic systems perspective to understand existing problems associated with apple production in China and use this information to improve its sustainability. A structure...

Rapid socio-economic changes in China, such as land conversion and urbanization, are creating new scopes for the application of precision agriculture (PA).An experiment to assess the economic benefits of two precision agriculture methods was applied for one year – precision seeding and precision seeding with land leveling. Whilst the results for th...

Forests worldwide are facing increasing pressures, with human travel and trade assisting the spread of pests and diseases. Climate change is likely to enhance the negative impacts of pests and diseases, which cause global declines and local extinctions. In this research we focus on three local and regional knowledge networks in the UK concerned wit...

Precision agriculture (PA) technologies offer a potential solution to food security and environmental challenges but, will only be successful if adopted by farmers. Adoption in China lags behind that in some developed agricultural economies despite scientifically proven benefits of PA technologies for Chinese agriculture. Adoption is dependent on f...

p>VALITEST is an EU-funded project built to improve the reliability of diagnostic tests performed in plant health laboratories across the European and Mediterranean region. The project is undertaken by a consortium of 16 partners composed of research institutions, private companies (such as diagnostic kit providers), national plant protection organ...

Plant health is relatively poorly funded compared with animal and human health issues. However, we contend it is at least as complex and likely more so given the number of pests and hosts and that outbreaks occur in poorly monitored open systems. Modelling is often suggested as a method to better consider the threats to plant health to aid resource...

The impact of agricultural cooperatives on apple farmers’ technical efficiency (TE) in China was examined. The cooperatives were divided into two groups: a collective marketing group for farmers and an equivalent non-marketing group that did not provide a marketing service, although other functions remained the same. Using the propensity score matc...

In order to prevent and control the emergence of biosecurity threats such as vector-borne diseases of plants, it is vital to understand drivers of entry, establishment, and spatiotemporal spread, as well as the form, timing, and effectiveness of disease management strategies. An inherent challenge for policy in combatting emerging disease is the un...

Invasive alien species (IAS) are one of the most severe threats to biodiversity and are the subject of varying degrees of surveillance activity. Predictive early warning systems (EWS), incorporating automated surveillance of relevant dataflows, warning generation and dissemination to decision makers are a key target for developing effective managem...

Land produces a range of benefits, from ecosystem services, but markets only incentivise the production of a small proportion of them. The Ecosystem Approach develops plans for moving towards a more optimal mix. This requires stakeholders to understand the value of ecosystem services and how these values change with land-use and management. We inve...

Precision agriculture has the potential to deliver improved and more sustainable food production. Despite the various Chinese policy initiatives to strengthen national food security, there is evidence that the adoption of precision agriculture technologies in China has been much lower when compared to other developed agricultural economies. This st...

Ash dieback Hymenoscyphus fraxineus (T. Kowalski), is an alien fungal disease probably introduced to Europe from Asia that currently presents a significant threat to native ash (Fraxinus L. spp.). In the United Kingdom a large proportion of ash trees are found outside of woodlands. This means that a wide diversity of land owners and managers are st...

The challenges to forest health from climate change, globalization, contemporary trade practices and new recreational patterns require effective biosecurity. We asked: How is the biosecurity border for tree health understood and enacted by state and non-state actors? What are the consequences for tree health? Semi-structured interviews (N = 10) wer...

Precision agriculture (PA) technologies have great potential for promoting sustainable intensification of food production, ensuring targeted delivery of agricultural inputs, and hence food security and environmental protection. The benefits of PA technologies are applicable across a broad range of agronomic, environmental and rural socio-economic c...

This chapter presents an overview of how economics considers plant pests and disease, the tools available to assess possible responses and how economics interacts with policy making. Plant health exhibits a number of public good characteristics that suggest the need for public intervention—left to its own devices, the market would underprovide bios...

Technological innovations demand interactions across academics, end-users and commercial stakeholders if they are to be ‘fit for purpose’. Stakeholder engagement can enhance the efficacy of new biosecurity technologies, increase buy-in as well as uptake and build relationships to increase ‘preparedness’. We explore the role of stakeholder engagemen...

Valuing amenity trees is important for calculating loss of amenity and replacement value following wilful or negligent damage, and for several aspects of urban forest management: planning, budget setting and decision-making. Capital Asset Value for Amenity Trees (CAVAT) is a tool for valuing amenity trees; it was first presented publicly in 2003. I...

There is concern that insect pollinators, such as bees, are currently declining in abundance, and are under serious threat from factors such as increased use of certain pesticides, land use changes, competition from invasive alien species, pathogens, parasites and climate change. Using the contingent valuation (CV) method, this paper evaluates how...

1. Many alien taxa are known to cause socio-economic impacts by affecting the different constituents of human well-being (security; material and non-material assets; health; social, spiritual and cultural relations; freedom of choice and action). Attempts to quantify socio-economic impacts in monetary terms are unlikely to provide a useful basis fo...

Near real-time epidemic forecasting approaches are needed to respond to the increasing number of infectious disease outbreaks. In this paper, we retrospectively assess the performance of simple phenomenological models that incorporate early sub-exponential growth dynamics to generate short-term forecasts of the 2001 foot-and-mouth disease epidemic...

Veterinary medicinal products (VMPs) require, as part of the European Union (EU) authorization process, consideration of both risks and benefits. Uses of VMPs have multiple risks (e.g., risks to the animal being treated, to the person administering the VMP) including risks to the environment. Environmental risks are not directly comparable to thera...

Background Antimicrobial resistance is becoming a major threat to public health and there is much current activity to ameliorate that threat. However, the relative contributions that potential sources of antimicrobial resistant (AMR) bacteria represent are not well established. Over-prescription of antimicrobials by clinicians is one source of sele...

Heritage gardens, heathland and woodland are increasingly under threat from the non-native tree and plant diseases Phytophthora ramorum and Phytophthora kernoviae. However, there exist only limited literature that estimates the public non-market value that may be lost from a continued spread of Phytophthora ramorum and Phytophthora kernoviae into t...
