University licensing of patents for varietal innovations in agriculture

There has been a sharp increase in the number of patented agricultural varieties from public universities in the United States. We develop an experiment to examine the revenue stream to universities from licensing plant‐based innovations. In the experiment we asked subjects to bid for access for a patented input that would be used to produce a differentiated product; treatments were employed to solicit bids that were financed by fees, royalties, and a combination of the two mechanisms under exclusive and nonexclusive contracts. The literature studying the economics of downstream duopoly competition in quantity suggests that revenues for the innovator would be greatest under a nonexclusive contract that uses fees and royalties. In our experiment we allow more than two firms to obtain access to the patent in the nonexclusive treatments, and our empirical results suggest that innovator revenues are greatest when royalties are used alone in a nonexclusive contract.     

Exploring farmer perceptions of agricultural innovations for maize-legume intensification in the mid-hills region of Nepal

Maize-legume intercropping is a fundamental component of mixed farming systems in the mid-hills of Nepal. However, its productivity is constrained by several biophysical and social factors, and limited adoption of proven agricultural innovations. In this study, we assessed the productivity impact of a selection of relevant agricultural innovations and changes in the associated perceptions of farmers through a series of two-year participatory on-farm trials. The evaluated innovations resulted in higher yields as compared to farmers' current practices. The active involvement of farmers enlarged our understanding of underlying decision-making factors to adopt or non-adopt agricultural innovations. Additionally, the in-depth farmer engagement in our onfarm trials positively influenced farmer perceptions of the innovations and their interest to adopt the agricultural innovations. Yet, farmers final decisions to adopt some of the evaluated innovations were limited by a host of factors including labour scarcity, the availability of inputs, and by cultural preferences despite the increased yields. This was particularly true for low and medium resource-endowed farmers. This study shows the importance of active farmer participation and context-specific design of research and development projects aiming for local impact.     

The optimal diffusion of mitigation options for environmental management

A new direction for evaluating pollution policy is proposed, focused on optimal investment pathways for mitigation capital. The approach allows practitioners to draw directly from key principles in the diffusion literature. A two‐stage, policy‐development framework is introduced. The first stage consists of empirical modelling to assess optimal diffusion pathways for diverse mitigation options. The second involves determining the relative strengths of different policy actions to address diffusion rates or maximum levels of adoption that diverge from optimal levels. The advantages of this new approach are demonstrated in an agri‐environmental context, concerning the off‐site impacts of intensive agriculture on water quality. The viewpoint provided by the novel approach establishes the importance of adoptability – alongside the traditional measures of abatement effectiveness and cost – for mitigation practices in policy assessment. The key role that durable mitigation capital plays in addressing dynamic externalities is demonstrated, alongside the importance of structured diffusion cascades for alternate mitigation options.     

The fourth industrial revolution,agricultural and rural innovation,and implications for public policy and investments: a case of India

The Indian Government and public–private partnerships are developing and disseminating a dizzying number of innovative, networked solutions, broadly known as the Digital India initiative, to increase the efficiency of safety nets and worker productivity and to improve life. Yet, challenges to turn the power of information and other technologies into a farmer‐friendly technological revolution for India's 156 million rural households are considerable, including: (1) reliable, up‐to‐date, location‐specific message content for a diverse agriculture to help stratified households shift to productive, knowledge‐intensive agriculture as a business—government, private sector, and civil society have big roles to play; (2) digital literacy, i.e., teaching farmers how to choose and use apps, even where the digital divide is absent; apps are, or soon to be, in regional languages; and (3) monitoring actual use and impacts on users’ lives by understanding the adoption and adaptation processes. These challenges call for bottom‐up, complementary investments in physical, human, and institutional capital, and farmer‐friendly e‐platforms, while forging ahead with many top‐down policy and institutional reforms currently underway, in which progress is real and constraints holding back greater success are better understood.     

Multi-year assessment of Unilever's progress towards agricultural sustainability II: outcomes for peas (UK), spinach (Germany,Italy), tomatoes (Australia,Brazil, Greece,USA), tea (Kenya,Tanzania, India) and oil palm (Ghana)

The foods, home and personal care company, Unilever, is a large user of raw materials from agriculture, and a major buyer of goods on world markets. The continued supply of these materials is seen as an important component in the business's long-term success. The company has a long history of seeking to farm responsibly on company farms and for directly contracted raw materials, but it became clear that an approach based solely on suppliers' good agricultural practice would not safeguard supplies where increasing social and environmental pressures on agriculture were growing, or where increasing consumer concerns about the food chain could undermine markets and brands. Both threats suggested the need for a more radical approach. This resulted in the development of a mission statement, the agreement of four principles for sustainable agriculture, the identification of ten sustainable agriculture indicators (later 11), and the selection of five key crops the sustainable supply of which was significant to the company.

This paper summarizes progress towards the sustainable supply of these crops by reporting on selected sustainability indicators for the crops (peas, spinach, tomatoes, tea and oil palm) in 11 countries. Some of the businesses using these products have been subsequently sold, but these are reported here because the aim is to explore how responsive are different indicators of sustainability to management action in different crops in widely differing locations. This paper focuses on a selection of findings for each of the 10 indicators, in order to illustrate the extent of changes that have been observed over time. These also indicate some of the difficulties faced in making improvements on the ground. The gathering of data on sustainability indicators is closely tied to the development of alternative practices that should quickly deliver improvements in a variety of outcomes. An assessment is also made of the key changes that have occurred for each of the main five crops as a result of adopting the sustainability indicator system and associated new management practices.

Multi-year assessments were conceived as the way to understand and demonstrate progress towards more sustainable agriculture. The important developments were of systems that combined ensuring that agricultural suppliers performed to an acceptable set of criteria, and then had the capacity and willingness to identify the most critical areas where further progress was required. The challenge for the company is now to encourage others to adopt their approach to making supply chains more sustainable, both for their customers and the consumers of their branded goods.
