Scientists develop decision support systems (DSSs) to make agricultural science more accessible for farmers and extension officers. Despite the growing use of participatory approaches in agricultural DSS development, reflection on this endeavour has largely focused on the ‘doing’ of participation or the ‘problem of implementation’ when DSSs have not been adopted by stakeholders. There has been little reference to relevant theoretical approaches to the social processes involved in ‘participation’ or ‘ ...

In agriculture, value chain research provides a capacity to increase efficiencies, business integration, responsiveness and ultimately market competitiveness. In sugar, such research has expanded rapidly over the past two decades, and has been motivated by low world sugar prices and rising costs of production. In this paper, we highlight the future opportunities in value chain research to achieve more profitable and sustainable sugar industries in different countries. We do this by: (a) conducting ...

Transformative actions are increasingly being required to address changes in climate. As an aid to understanding and supporting informed decision-making regarding transformative change, we draw on theories from both the resilience and vulnerability literature to produce the Adaptation Action Cycles concept and applied framework. The resulting Adaptation Action Cycles provides a novel conceptualisation of incremental and transformative adaptation as a continuous process depicted by two concentric ...

Decision support systems (DSSs) are one of the ways in which agricultural scientists have attempted to make agricultural systems science more accessible to farmers and to foster innovation. Recently, there has been a shift towards more participatory processes in development and application of DSSs to enhance their end-user use. Apart from increasing adoption, these participatory processes are also likely to enhance co-learning resulting from development/application of DSSs. Learning is a valuable ...

The tendency toward higher packing densities and higher frequencies for telecommunication devices based on ceramic technology requires smaller dimensions for electrical wiring. Electrical thick-film circuits for ceramic and LTCC-substrates have, up to now, been printed with screen printing, where the printing lines width limit is about 125 /spl mu/m in mass production. A silicone polymer direct gravure printing (Si-DGP) process has been developed to perform smaller dimensions, down to 20 /spl mu/m ...

The food industry is vulnerable to climate change. Producers will need to adapt to climate change if they, and the communities dependent on them, are to remain viable. There are essentially two ways to adapt—incrementally and transformationally. We differentiate between incremental and transformative adaptation mostly on the basis of the size of the change needed. Here, we studied the Australian peanut industry, which is already experiencing the effects of climate change. We expand on the notion ...

Primary resource industries considering adaptation action in response to current or future climate changes need to consider the adaptive capacity of their constituent members if an industry-wide response is to occur. In particular, they need to know the extent to which the capacity to adapt exists and whether it can be enhanced. We focus on the role of climate change awareness in influencing adaptive capacity within an Australian primary industry that is already experiencing the impacts of climate ...

There is increasing interest in transformational adaptation to climate change in agriculture, i.e. adaptation that involves large-scale, novel responses to reduce vulnerability to climate risks. Transformational adaptation is less well understood than incremental adaptation, since there are few studies of agricultural enterprises making transformative changes in response to climatic change. This paper is an in-depth study of an agricultural company's attempt to implement transformational adaptation ...

Continued population growth and land intensification put increasing pressure on agricultural production and point to a need for a ‘step change’ in agriculture to meet the demand. Advances in digital technology—often encapsulated in the term ‘big data’—are increasingly assumed to be the way this challenge will be met. For this to be achieved, it is necessary to understand the ways that farmers and other industry stakeholders perceive big data and how big data might change the industry. It is also necessary ...

Advances in Smart Farming and Big Data applications have the potential to help agricultural industries meet productivity and sustainability challenges. However, these benefits are unlikely to be realised if the social implications of these technological innovations are not adequately considered by those who promote them. Big Data applications are intrinsically socio-technical; their development and deployment are a product of social interactions between people, institutional and regulatory settings, ...

A highly selective isophorone‐boronate ester based chemosensor, ( 1 ) , having a dicyanovinyl moiety as a convenient colorimetric probe, has been designed. Different types of anionic analyte such as CH 3 COO − , ClO 4 − , Cl − , F − , PF 6 − , Br − and HSO 4 − were tested and among them only highly nucleophilic F − anion displayed significant response towards the sensor. Addition of the fluoride anion across the boron atom disrupts the π‐conjugation thereby shifts the absorption wavelength towards the redshift region due to the ...

This perspective paper integrates theories of responsible innovation (RI) with the nascent development of the concept of mission-oriented innovation to address wicked socio-institutional challenges. Theoretically, steering a Mission-oriented Innovation System (MIS) and associated 'mission arena' toward activities that create virtuous cycles of RI practice will lead to cumulative impacts on the evolution of innovation system cultures. We explore this claim using nascent future-oriented 'missions' developing ...
