Indonesia is the world's 3rd largest cocoa producer, producing around 400,000 tonnes pa of cocoa, primarily in small family farms, and this industry contributes ~14% to GDP. Cocoa farming is the main source of income for more than one million smallholder farmers and their families, therefore the economic and environmental sustainability of cocoa production is key for the long-term social and economic stability of farming communities. The sector though is facing significant technical and business challenges which lead to low farming productivities and consequently to low profitability for farmers. Despite a number of public-private initiatives over the last 8 years, significant changes are still needed to improve the sustainability of cocoa production and have an impact on farmers' welfare and economic stability. These include implementing best-known farming practices (e.g. efficient use of fertilisers and pesticides), developing approaches for the exploitation of by-products, improving post-harvesting techniques for cocoa beans, improving infrastructure and transportation, developing education and training programmes for farmers and promoting the development of farmers' co-operatives. The commercial exploitation of cocoa pod husks through their conversion to added-value products, such as biomaterials for food and non-food uses, is a promising strategy and a timely opportunity to address effectively and efficiently some of the sustainability issues of cocoa production. This is high up on the R&D agenda of our industrial partner (Mars Chocolate Ltd) and Indonesian government agencies. Currently, most farmers, after extracting the beans, leave the pod husks on cocoa plantations. This can return some nutrients to the soil (in the absence of any other fertiliser being used), but untreated pod husks can lead to increased pest and disease pressure from cocoa pod borer moth and black pod disease, thus decreasing the productivity of the farms. The aim of the project is to develop a novel value chain for cocoa pod husks which upon implementation will have an impact on the economic stability and welfare of cocoa farmers. The specific objectives are to: (i) elicit the willingness of farmers in Indonesia to adopt the proposed practice changes and assess how these might be aligned with farmers' preferences; (ii) develop scalable process designs for the efficient fractionation of cocoa pod husks into non-soluble fibre, soluble fibre and lignin fractions; (iii) identify and evaluate value-adding applications for such fractions with market potential within the food and non-food sectors; (iv) understand the potential impacts on soil properties and soil nutrient cycling of off-farm removal of husks; and (v) propose a supply chain based on scale and mode of operations (e.g. centralised or decentralised) and evaluate the economic viability from a farmer's and private sector perspective. Developing a new value chain based on the use of cocoa pod husks husks will minimise potentially negative environmental effects associated with their disposal and diversify the activities of farmers through the collection, primary processing and transportation of the husks. All these changes will considerably improve the sustainability of cocoa production. This can potentially have significant impact on the farmers' economic stability and welfare through increased household income, incorporation of modern and sustainable farming practices, public-private investments in infrastructure, manufacturing operations and transportation, introduction to new technologies, development of new skill sets, creation of jobs and entrepreneurial opportunities. The project's outcomes will make a strong case for use of the novel value chain and identify the socio-economic and technological challenges (e.g. adoption of new farming practices by farmers, process efficiency and scalability) and opportunities as well as the risks for its successful implementation.

Soft materials include colloids, polymers, emulsions, foams, surfactant solutions, powders, and liquid crystals. Domestic examples are (respectively) paint, engine oil, mayonnaise, shaving cream, shampoo, talcum powder and the slimy mess that appears when a bar of soap is left in contact with a water. High tech examples of each type are used in drug delivery, health foods, environmental cleanup, electronic displays, and in many other sectors of the economy. Soft materials also include the lubricant that stops our joints scraping together; blood; mucus, and the internal skeleton that controls the mechanics of individual cells. The intention of this Programme is to use a combination of theoretical and experimental work, alongside large scale computer simulation, to establish scientific design principles that will allow the creation of a new generation of soft materials demanded by 21st Century technologies. This will require significant advances in our scientific understanding of the generic, as well as the specific, connections between how a material is made and what its final properties are. As soft materials become more complex and sophisticated, they will increasingly involve microstructured and composite architectures created from components that may be living, synthetic, or a combination of the two. The design principles we seek will ultimately allow scientists to start from a specification of the interactions between these components, and then create new materials by intentional design, rather than simply trying out various ideas and hoping that one of them works. There could be great rewards from being able to do this. Even in long-established industries (such as the food industry, home cleaning, personal care products, paints etc.) products made of soft materials are continually being updated or replaced. This is often in order to make them healthier, safer, or more environmentally friendly to produce. Currently, however, the process of developing new soft materials, or improving existing ones, usually involves a large element of trial and error. A set of design principles, based on secure fundamental science, could speed up that process. This would reduce costs, increase competitiveness, and improve the well-being of consumers. The benefits would be even greater in new and emerging industries such as renewable energy. Soft composite materials have many potential applications for use in high-energy low-weight batteries; low cost solar cells; hydrogen fuel cells; and possibly biofuels. However the design requirements for these applications are demanding, and often involve quite complex microstructures with specific functionality. The same applies in other emerging areas, such as industrial biotechnology and tissue engineering, where soft materials are used to create specific environments in which enzymes, cells or other live components can be used to perform particular tasks. As well as shortening lead-times and costs, by establishing the general principles needed to put new design ideas into practice, we hope to allow innovative soft-matter products to be created that otherwise might never come to market at all.

Our GCRF TRADE Hub addresses a global challenge that has led to dramatic decline in biodiversity and ecosystem resilience in the past century, and if not addressed will significantly imperil the development of lower income nations. Trade in wildlife and agricultural commodities from low and middle income to higher income countries has increased rapidly over the last decades, and is projected to expand rapidly into the future to meet demands. Although trade is vital for national development, it also can carry heavy environmental and social costs, particularly for poor rural people in DAC countries, mainly because there is a great imbalance of power within the decision-making system and the most affected people are relatively powerless and voiceless in the decision-making process. The development of these trades over the past decades have has also resulted in considerable impacts on natural systems, threatening with extinction thousands of species globally. Addressing the issue of balancing the positives of ever-expanding trade with its costs is essential to addressing several of the SDGs, to protect and promote livelihoods within vulnerable communities in DAC countries, and is important for the UK in terms of negotiating sustainable trade deals that also meet other environmental and social development commitments. The Hub will work on a number of key trade flows that are particularly important to our focal developing countries and the UK, and where we have existing strengths that will allow us to have real impact in the lifetime of the Hub. This will include trade that has a direct impact on biodiversity - for example the global trade in wildlife for a range of uses, including the regional and national trade in wild meat. It will also include agricultural commodity trades that have indirect impacts on biodiversity through conversion or degradation of habitats. Its strong international and interdisciplinary research team, including economists, trade modellers, political scientists, ecologists and development scientists, will produce novel, impact-orientated research. Through involving companies, UN-related trade bodies and governments, the project will be embedded in the needs of the economy and development at large. We have ten work packages: During the project design phase WP0 will further elaborate a detailed theory of change and mapping exercise leading to the co-design of the research programme with critical stakeholders (private sector actors, trade organisations and NGOs). This will lead into the delivery of eight interlinked work packages: WP1: Understanding wildlife trade from DAC countries (live animals, skins, non-timber products, wildmeat) at the supply end; volumes and characteristics of local and export trade, and impacts on biodiversity and resource users; WP2: Understanding supply to demand-end agricultural commodity trade pathways, volumes and characteristics, within and exported from DAC countries; WP3: Determining the magnitude and spatial-temporal distribution of social benefits and costs for selected wildlife and commodity supply chains from the supply to demand ends; WP4: Understanding how trade and economic policies impact on wild-sourced and agricultural commodity trades and their impact on people and nature; WP5: Modelling the implementation of different scenarios of trade policy and corporate decision making; WP6: Developing solutions and building capacity through engagement with the private sector (large corporations and investors); WP7: Developing solutions and building capacity, through engaging with trade public sector rule-setting agencies and national policy makers; WP8: Outreach and Technology Solutions. We also have a cross-cutting WP9: building DAC partner capacity to ensure ongoing, sustainable research-led solutions to TRADE's intractable challenge. We involved DAC countries, corporations, investment bodies, and UN-linked trade agencies in the co-design of this Hub from the outset.

It is a major problem to exploit the new ideas emerging from the Photonics/Plasmonics/Metamaterials academic community (in which the UK is strong) for real-world applications. In this field, the intricate structure of metals and dielectrics on the nanoscale produces radically new optical properties which are the basis for many devices and materials. However because the nanoscale architectures are designed by academics with little thought to manufacturability, most of these ideas founder very early against cost, method and volume considerations. We aim to invert this model, examining much more seriously a number of different fabrication routes that look promising for delivering scale-up of manufacturing nanostructures with novel and useful photonic materials and metamaterials functionality. However, blind approaches from considerations only of manufacturability are unlikely to locate useful functionalities. As a result we are strongly guided by a set of successful platforms developed over the last 5 years, which already embed the promise of scale-up due to their use of bottom-up self-assembly. In this programme, we develop such directed-assembly towards real capabilities for manufacturing. Success in this domain will be directly exploited by a number of UK companies, both large and small, but even more importantly will be transformative for UK approaches to manufacturing. Despite huge investments in top-down nanofabrication in the UK, little commercial return has been produced. Alternative approaches based on self-assembly already have traction (for instance inside Unilever), and offer routes to mass-scale production with a cost model that is realistic. What industry needs is not the ideas, but a well-developed research programme into the manufacturing space that will allow them to make use of these advances. Our programme will deliver this through tightly coupling nanoassembly, nanophotonics, and nano-manufacturing.

Soft matter and functional interfaces are ubiquitous! Be it manufactured plastic products (polymers), food (colloids), paint and other decorative coatings (thin films and coatings), contact lenses (hydrogels), shampoo and washing powder (complex mixtures of the above) or biomaterials such as proteins and membranes, soft matter and soft matter surfaces and interfaces touch almost every aspect of human activity and underpin processes and products across all industrial sectors - sectors which account for 17.2% of UK GDP and over 1.1M UK employees (BIS R&D scoreboard 2010 providing statistics for the top 1000 UK R&D spending companies). The importance of the underlying science to UK plc prompted discussions in 2010 with key manufacturing industries in personal care, plastics manufacturing, food manufacturing, functional and performance polymers, coatings and additives sectors which revealed common concerns for the provision of soft matter focussed doctoral training in the UK and drove this community to carry out a detailed "gap analysis" of training provision. The results evidenced a national need for researchers trained with a broad, multidisciplinary experience across all areas of soft matter and functional interfaces (SOFI) science, industry-focussed transferable skills and business awareness alongside a challenging PhD research project. Our 18 industrial partners, who have a combined global work force of 920,000, annual revenues of nearly £200 billion, and span the full SOFI sector, emphasized the importance of a workforce trained to think across the whole range of SOFI science, and not narrowly in, for example, just polymers or colloids. A multidisciplinary knowledge base is vital to address industrial SOFI R&D challenges which invariably address complex, multicomponent formulations. We therefore propose the establishment of a CDT in Soft Matter and Functional Interfaces to fill this gap. The CDT will deliver multidisciplinary core science and enterprise-facing training alongside PhD projects from fundamental blue-skies science to industrially-embedded applied research across the full spectrum of SOFI science. Further evidence of national need comes from a survey of our industrial partners which indicates that these companies have collectively recruited >100 PhD qualified staff over the last 3 years (in a recession) in SOFI-related expertise, and plan to recruit (in the UK) approximately 150 PhD qualified staff members over the next three years. These recruits will enter research, innovation and commercial roles. The annual SOFI CDT cohort of 16 postgraduates could be therefore be recruited 3 times over by our industrial partners alone and this demand is likely to be the tip of a national-need iceberg.
