Environmentally sustainable small-scale rice production mechanisation is a feasible intervention to help enhance yields and reduce food insecurity. Using machinery for rice production can help small farmers economically and promote sustainability through agroecological principles. The study analyses machinery ownership models and suggests stakeholder interactions for sustainable rice production. The study uses primary data from a field survey of 320 farmers within Asutsuare, a rice production hub in Southern Ghana, and secondary data from various sources. Four different ownership models have been proposed and evaluated. The cooperative-owned machinery (COM) model, with a sharing of the initial investment capital outlay for the machinery acquisition, and the individual ownership model, where the farmer owns and offers hiring services to other farmers (the FOHM-2B and FOHM-2T models) were the most economically viable models. The study also identifies necessary stakeholder engagement and pathways for affordable, sustainable, mechanised small-scale rice production. The models and interactions can promote machinery ownership and strengthen social connections in the community. This local knowledge base can help expand the use of machinery within the community. These models and interactions can be replicated easily in Sub-Saharan African farming communities with similar dynamics. This will improve mechanised farming throughout the continent.

Municipalities in the UK are increasingly engaging in local management of one or more parts of the energy system. The municipal energy companies set up to manage this engagement have the potential to contribute to a low-carbon transition through acceleration of low-carbon energy technology roll-out and demand management. However, municipal energy companies face many constraints that limit their growth in number and scale and restrict their potential to contribute to climate change mitigation. This paper aims to develop a better understanding of why and how municipal energy companies form to help to identify how policy and regulation could better support their proliferation and their contribution to climate change mitigation. We conducted a longitudinal analysis (from 2013 to 2017) of five UK cities’ attempts to develop new institutional arrangements to engage in the national energy system and contribute to climate change mitigation. We found that the fundamental purpose of municipal energy companies was different to those of the private sector; using energy to deliver essential services and place-specific outcomes, rather than aiming to deliver energy at least cost. The scope of engagement was dependent on a city’s unique characteristics and factors driving decisions. We found that there was no blueprint for a municipal energy company, rather the final form was shaped by a city’s unique characteristics and decision drivers and emerged from a process of experimentation and learning. This ‘pathway’ towards a municipal energy company is also heavily influenced by the changing policy context, meaning that studying the evolution of municipal energy companies over time is very important. Specific changes in UK policy have significantly reduced the potential of municipal energy companies to contribute to carbon emissions reduction. We propose a framework of characteristics, decision drivers and pathways to better understand the evolution of municipal energy companies and to support the identification of policy and regulation that could enable their proliferation. We illustrate the application of this framework to maximise the contribution of municipal energy companies to climate change mitigation in cities. We identified a need for policy to recognise and enable different institutional drivers (including climate change) and institutional forms and encourage experimentation. Furthermore, new approaches to accounting and valuation are needed that capture social and environmental outcomes and outcomes that occur in the long-term. [ABSTRACT FROM AUTHOR]

Meat consumption behaviours contribute significantly to global greenhouse gas emissions. Interventions to enable meat consumption reductions need to consider the psychological barriers preventing behavioural changes. Our aims were twofold; (1) to explore the psychological barriers to reducing meat consumption and how they can be overcome through a Rapid Evidence Review; and (2) to explore the usefulness of integrating the Kollmuss and Agyeman (K&A) model of pro-environmental behaviour and psychological distance, which provides the analytical framework. This review utilised three databases, focussing on empirical studies since 2010, which returned 277 results with seven eligible studies. We found that habit is the most significant psychological barrier to change, however, values and attitudes could act as moderating variables. We found gaps in the behavioural mechanism, indicating the presence of direct and indirect psychological barriers. We identified several actionable policy recommendations, such as utilising co-benefits, the importance of values in messaging, and targeting repeated behaviours. We found that study outcomes did not always translate into policy recommendations, and they were limited by existing policy paradigms. Psychological distance provides additional explanatory power, when combined with the K&A model, therefore, integrating psychological distance across pro-environmental behavioural research and policy could improve the effectiveness of interventions.

This paper explores the relationships between the moral philosophical foundations and strategic goals of two conceptions of energy justice: the "triumvirate conception" and the "principled approach". We explore the extent to which the goals of these approaches align with their core aims and strategies. Having initially been developed to capture and reflect the values of activist-led environmental justice movements, we find that the triumvirate approach's adoption of a trivalent conception of justice currently lies in tension with its overarching top-down approach. We note that the principled approach does not face the same tensions as the triumvirate conception of energy justice, but would benefit from illustrating the consequences of framing the same energy dilemma with conflicting moral theories. Aiming to ameliorate these limitations and further develop conceptions of energy justice, we outline a case study of hydro power in Hirakud, India and propose a framework which illustrates how using differing theories of justice to conceptualise the same energy dilemmas can result in substantially different normative framings and guidance. We illustrate how this framework, combined with a pluralistic appeal to moral theory, can enable both approaches to draw on a wider range of moral theory to assess energy dilemmas. This in turn provides a broader socio-political backdrop in which to view energy dilemmas. We outline how this backdrop contributes to the creation of a space in which the grievances of those who suffer in relation to energy systems can be heard and better understood. [ABSTRACT FROM AUTHOR]
