Political and Economic Contexts (15 credits)

The trade in horticultural produce and commodities is dependent upon a variety of political and economic factors. An awareness of these and how they affect markets in both the national and international contexts is a vital part of modern horticultural business enterprise. The impact and influence of consumer demands and values, and trade agreements is closely examined as is the role of international legislation on areas such as climate change and the environment, packaging and labelling. Assurance schemes such as GlobalGAP, HACCP and BRC or equivalents are covered as are policy drivers for climate change action, biodiversity conservation and human well-being. Key issues on renewable energy, sustainable resource management and payment for public services are integral elements of the module.

Fresh Produce Production (15 credits)

Fresh produce sales in UK supermarkets are worth approx. £10.8 billion. A supply of nutritious affordable foods for public health that meets the five a day campaign requires production and supply systems that assure high standards of quality and safety. The UK is currently reliant on imports and this a sector that is seeing fast paced change and innovation both in the UK and world agricultural systems. The module will give you the opportunity to assess developments and the potential of fresh plant produce production including root, salad and fruit crops which are of increasing importance in certain parts of the UK and overseas, where they contribute significantly to farm output. It will look at the role of this sector to the UK economy, EU imports and from a global perspective. This module will connect with other key modules to consider production systems and consumer behaviour in terms of dietary needs and food preferences in the UK. Its content will keep pace with rapid change through industry engagement and will be delivered in the context of food security, imports and exports, the resilience of supply changes, marketability, consumer demands, waste and sustainability. The content will look at products that can uphold standards of quality, plant health and sustainability. The opportunity to focus on the ornamental and flower production sector is also included part of the module. Specific crops will be evaluated and the agronomy discussed within the framework of Integrated Farm Management to promote the sustainable techniques and the production of high quality produce for multiple retailers and specific markets. Management issues will be evaluated to assess the factors necessary to produce high value field crops profitably while operating within the parameters of environmental sustainability and social values. The opportunity to apply concepts to novel crops and production systems and evaluate developments will also be included. Current developments in technology and those intended to operate within circular economic principles, to reduce ecological footprint and minimise waste output, will be evaluated along with the requirements of highly perishable crops as these are likely to make significant contributions to the efficient production of marketable produce in the future. The opportunity to work with the sector and visit local farmers, processors, packers and retailers will form part of the module.

Year 3

Natural Resource Management (15 credits)

In the last 50 years global gross domestic product has doubled, enabling immense progress in parts of the world, and providing a quality lifestyle for millions of people. However, this economic growth has been fuelled by grossly unsustainable demands on the planet’s natural resources. Overexploitation together with the production of non-recyclable waste and pollution has driven many of the natural ecosystems into a state of collapse or irreversible change. Estimated boundaries of tolerance for ecosystem structures and function, including biodiversity, climate and nitrates have been exceeded. The United Nations 2019 Global Resources Outlook report reveals that 90 per cent of biodiversity loss and water stress are caused by resource extraction and processing. These same activities contribute to about half of global greenhouse gas emissions. Moreover, the benefits of this type of resource use disproportionately limited to a relatively small section of global society in developed parts of the world. High-income countries maintain levels of per capita material footprint consumption that are 60 per cent higher than upper-middle income countries and more than thirteen times the level of the low-income countries. Economic growth which comes at the expense of our planet is simply not sustainable. Through the theory and principles of systems science this module critically examines cause-effect dynamics and drivers of change in land use management, and the implications of unsustainable global food systems and natural resource management on climate, biodiversity and human well-being. The complexity of the problem is a central tenet, and so the need to adopt a multidisciplinary approach is emphasised throughout: one that interrogates current problems in land use practice through the lenses of contemporary scientific theory, specifically, complex systems theory, ecosystem theory and principles of adaptive management. Using case studies, you are tasked with analysing models of sustainable development and nature based solutions, and to work with concepts of cooperative, multidisciplinary and multi-stakeholder based approaches.

International Trade and Markets (15 credits)

The trade in horticultural produce has become increasingly internationally based, with many countries involved in the trade of produce. Ensuring the reliability of trade and supply lines is a key aspect within this, as are the systems used to assure quality and safety of various products. This module sets out to examine the causes and types of food loss as well as where it occurs in the food chain and systems. The aim is to illustrate the variety of methods available to reduce loss through packaging, training appropriate equipment etc. Economics and sustainability are included in the debate on food loss, as is the relevance of Fairtrade. Reference to the UN sustainability goals will be implicit to discussions on future developments holding central the tenets of social justice, ethical business and human well-being. You also become acquainted with the methodologies associated with measurement of quality relating to biological change, as well as marketing requirements on local and global bases and the issues of health and food safety in day to day operations.

Crop Management and Technologies (15 credits)

This module will examine how the productivity of a crop is influenced by a combination of crop physiology, crop husbandry and crop technology. The yield potential of crops will be examined within the context of environmental change. Current topics of importance to the management of horticultural plants and crops will be debated.

Community Horticulture (15 credits)

This module critically examines the interaction between people and horticulture. As the majority of people live in towns and cities, the module will particularly, but not exclusively, be focused on urban communities and their environments. Communities are being empowered to take greater responsibility for their neighbourhoods from writing neighbourhood development plans through to asset management of behalf of the local authority. Community-run projects can bring many benefits but require co-ordination and co-operation. The module will critically evaluate how people within a community can be contacted and brought together through a range of community horticultural projects.

Managing Urban Blue Green Infrastructure (15 credits)

Urban landscapes that include green spaces (like parks and gardens), blue spaces (such as rivers and lakes and blue-green infrastructure (integration of both) offer significant benefits to the people who live and work in them, as well as being important in supporting biodiversity and offer key environmental services. These areas offer significant benefits to individuals and communities living in urban areas, impacting both human health and wellbeing, community cohesion and quality of life in built up cities and towns. Importantly they also offer ways of directly and indirectly mitigating climate change, which can capitalise on the diversity of horticultural species and promote sustainability contributing to climate risk reduction In this module, you’ll examine how these spaces can be used , how examples were planned and designed, with a focus on the choice of planting and the use of ornamentals, trees and green spaces examining their contribution and management today. The structural and functional benefits of plants in such environments will be examined. You’ll critically evaluate key legislation, strategy, research and policy measures relating to the protection and management of urban greenspace. There will be an opportunity to focus on examples such as private and community gardens, parks, recreational / open green space, green corridors, tree street and hedge planting, playing fields, rain gardens and the use of green roofs and walls alongside the aesthetic use of plants in green and blue infrastructure. The interrelationship and multifunctional use of these infrastructures such as water and flood risk management, thermal regulation, carbon capture and storage and supporting biodiversity will be considered in the context of public and environmental benefit.
