Agriculture diversification acts as income enhancing as well as distress mitigating strategy. India has witnessed rise in per-capita income which in turn has increased the demand for food particularly high-valued food items but agricultural production has failed to keep pace with the growing demand. The purpose of this paper is to examine spatio-temporal variations in agricultural diversification (AD) in India. Second, the authors try to identify the determinants of AD. Third, the authors examine the convergence hypothesis with reference to agriculture diversification across Indian states.

The study is based on the panel data constituting 20 major states of India during 1990–1991 to 2013–2014. It uses Simpson Diversification Index to measure AD. The heteroskedasticity-corrected panel regression model is applied to find out the determinants of AD. The fixed-effects model is used to examine β-convergence in AD across the sample states. Alternative time series models are applied to examine σ-convergence in AD.

The rising per-capita income and urbanization are driving dietary diversity towards high-valued crops and providing ample opportunity for AD. But poor and inadequate cold storage facility and rising cost of cultivation are posing major hindrance to it. Small land holding and road length have negatively influenced AD which is contrary to the traditional wisdom. The study found divergence in diversification and rising inequality in diversification.

The study is based on secondary data. A primary study to complement this could have been better. It is only based on one country.

Food inflation has serious adverse effect on the society at large. It is necessary to promote AD for controlling food price inflation. Minimum support price provided by the government should be extended to all crops; otherwise, it will fuel inflation. Given the fact fragmentation of land holding is adversely affecting AD, community based farming and consolidation of farm land should be the way forward to improve farmers’ income as well as reduce risk.

To best of the authors’ study, this is the first study that examines determinants of AD and convergence in AD during the high growth period of India.

Participation in urban horticulture (UH) is increasing in popularity, and evidence is emerging about the wide range of social and environmental benefits “grow your own” can also provide. UH can increase mental and physical well-being, as well as improve nature connectedness, social capital and community cohesion.

This study focusses on allotments, which is one of the dominant forms of UH that takes place in the United Kingdom. 163 volunteers in England and Wales participated in keeping a year-long allotment diary as part of a citizen science project investigating activities on allotment gardens. This study examines the unprompted comments that 96 of these gardeners offered as observations when visiting their allotment plots.

Participants recorded high levels of social and community activities including the sharing of surplus food produce, knowledge exchange, awareness and interaction with wildlife, emotional connection to their allotment, appreciation of time spent outside and aesthetic delight in the natural world around them.

At a time when waiting lists for allotment plots in the United Kingdom are on the rise, and allotment land is subject to multiple pressures from other forms of development, this study demonstrates that these spaces are important sites not only for food production but also health, social capital and environmental engagement.

This paper aims to explore the literature on vertical farming to define key elements to outline a business model for entrepreneurs. The research aims to stimulate entrepreneurship for vertical farming in a smart cities' context, recognising urban agriculture as technology to satisfy increasing food needs.

The research conducts a structured literature review on 186 articles on vertical farming extracted from the Scopus. Moreover, the bibliometric analysis revealed the descriptive statistics on this field and the main themes through the authors' keywords.

Different perspectives showed the multidisciplinary nature of the topic and how the intersection of different skills is necessary to understand the subject entirely. The keywords analysis allowed for identifying the topics covered by the authors and the business model's elements.

The research explores a topic in the embryonic stage to define key strands of literature. It provides business model insights extending George and Bock's (2011) research to stimulate entrepreneurship in vertical farming. Limitations arise from the sources used to develop our analysis and how the topic appears as a frontier innovation.

Originality is the integration of literature strands related to vertical farming, highlighting its multidisciplinary nature to provide a holistic understanding of the themes. In smart cities' context, innovations allow traditional business models to be interpreted in a novel perspective and revealed the elements for transforming vertical farming from innovative technology to an effective source of food sustenance. Finally, the paper suggests a new methodology application for the analysis of word clusters by integrating correspondence analysis and multidimensional scaling analysis.

Although people have always been aware of the role and importance of green space, trees, and other nature in cities, wider recognition and policy support is of a much more recent date, for example in the context of current climate and public health challenges. The nature-based solutions concept has emerged as a strong, recent attempt for “mainstreaming” of nature in political, planning, and economic areas. Starting from a description of the role of nature in cities, this chapter introduces the nature-based solutions concept and its current spread and implementation in an urban context. It also raises some questions about the next steps in implementing the concept, perhaps moving away from too much focus on a utilitarian view of nature and ecosystem and toward considering nature as a framework for all planning and decision-making.

The Edible Campus project was begun in spring 2007 in Montréal. An action-research project launched by volunteers and researchers from two leading local NGOs and university-based researchers (Alternatives, [online]; Santropol Roulant, [online]; McGill University's Minimum Cost Housing Group, [online]), it sought creative solutions to turn underutilised urban spaces into productive places. It involved citizens in the creation of green community spaces by incorporating productive growing in containers on a prominent but concrete-covered part of McGill University's downtown campus. Not only is it an investigation into making cities more food-secure by increasing urban food production, it is also a live demonstration of how ‘edible landscapes’ can be woven into urban spaces without diminishing their utility or functionality.

This chapter introduces the theoretical and political-practical underpinnings of this volume. It also gives an outline of the editorial organisation of the book and the various chapters. The chapter examines the literature on rural-urban relations, city-near rural areas and current challenges and problems identified in these areas. We identify huge sustainability and resilience problems in current rural-urban relations and metropolitan ruralities. We also relate to writings about a transition from the current carbon-based economy and society to a post-carbon society with reduced ecological footprints. The contributions in this volume are based on the current situation and provide ideas to develop the debate on rural-urban relations, metropolitan ruralities and post-carbon transition.

The purpose of this research is to determine institutional commitment to sustainability by examining Natural Resource Extension program inputs, activities, and participation.

A document analysis of Natural Resource Extension planning and reporting documents was conducted to provide contextual and historical data for the study and 58 in‐depth interviews were conducted with Natural Resource Extension personnel in the Alabama Cooperative Extension System and the Oregon State University Extension Service.

This research moves beyond the familiar teaching and research functions of higher education institutions and focuses on Cooperative Extension, which is the outreach arm of universities. The paper discusses challenges and opportunities associated with implementing sustainability through these outreach education programs. In both Alabama and Oregon, the Agriculture, Home Economics, and 4‐H programs dominate human and economic resource investment in Cooperative Extension. Natural Resource Extension programs in Alabama and Oregon represents 6 and 14 percent, respectively, of all program expenditures in Cooperative Extension. Both states have educational programs that address sustainability of natural resources and those programs were interdisciplinary in nature. Little evidence is found extensive participation in Natural Resource Extension programs by environmental groups, minorities, and other non‐traditional clientele. Lastly, Oregon's political context was more conducive to broadening Natural Resource Extension program work in sustainability.

Educational institutions such as Natural Resource Extension programs at universities play a significant role in educating private landowners, the public, and professionals about various aspects of forestry and natural resources. Based on this study of Natural Resource Extension programs in Alabama and Oregon, the following are needed for extension to address natural resource sustainability through its educational programs: sufficient intellectual and financial commitment to sustainability, diverse and inclusive participation in programs, and collaborative interdisciplinary programming. The analysis presented here can aid other educators as they explore sustainability through educational programming.

Since, Natural Resource Extension programs address societal concerns through problem solving, grassroots education, and research and technology dissemination, they are poised to do work in the sustainability arena. No study to date has examined sustainability from the aspect of Natural Resource Extension educators in Oregon and Alabama. An understanding of current investment in sustainability through education is fundamental to building a strong Extension program in this area.

Many higher education institutions are committed to developing students as skilled professionals and responsible citizens for a more sustainable future. In addition to the formal curriculum for sustainability education, there is an increasing interest in informal learning within universities. This paper aims to extend the current understanding of the diversity and significance of informal learning experiences in supporting students’ learning for sustainability.

Six focus groups were formed with 30 undergraduate and postgraduate students from an Australian higher education institution committed to supporting graduate competencies for sustainability. An inductive and qualitative inquiry was designed to enable participants to reflect on the ways in which their university experiences support meaningful and significant learning for sustainability.

The paper presents a typology of the diverse communities of informal learning that students create and engage with. These range from ongoing to transient groups, from environmentally to more socially oriented groups and from incidental to intended learning, from local to national in scale, with varying types and degrees of connection to the formal curriculum and the university campus. The paper demonstrates that these student-led experiences support three domains of learning: cognitive, practical and affective.

Deepening the understanding of the forms and significance of student-led learning within their university experience contributes to the identification of the roles that informal learning may play alongside formal education in developing graduates as agents of change for a more sustainable future.

The achievement of the sustainable development goals (SDGs) for all communities and jurisdictions require a comprehensive roadmap that encompasses all dimensions of data infrastructure, social, economic, environmental and governance ecosystems. With this in mind, this paper aims to establish the link between the curriculum and intended learning outcomes of undergraduate and postgraduate subjects offered by the University and sustainability. This study is a part of a wider university strategy to embed sustainability knowledge and values in the university curricula. The 17 SDGs developed as a part of the 2030 Agenda for Sustainability Development was used as tool to measure and map how the subjects are linked with sustainability.

To incorporate sustainability into the curriculum, this paper developed an interdisciplinary approach for analysing the interconnection between the SDGs, the expected subject learning points and the relevant aspects of sustainability (geospatial information, the legal, policies and institutional components). As part of the approach, in the first phase of the study, qualitative data were collected through a review of published information on the SDGs and the content of the subjects available in the subject handbook. Subject codes were assigned to the keywords and key phrases extracted from the SDGs and the subject content, and then compared and matched to establish the link between the subjects and the SDGs. Six university schools offering over 2,157 subjects were investigated. In the second phase, a survey was conducted involving subject coordinators with the purpose of validating the findings of the first phase and determining the strength of the linkages between the subjects and the SDGs. In the third phase, a plugin was designed to be used in the digital twin platform developed in the UoM, allowing visualisation of the research outcomes.

Based on the interim findings, it was found that some subjects within the schools are linked to more than one SDG. However, not all of the subjects within the schools can be linked to the SDGs. There is a scope of improvement for embedding sustainability in more subjects within the schools. Some of the schools were also found to have weak linkages with sustainability, which demonstrate the challenge in technical subjects in linking their subject contents with sustainability.

This study provides a methodology which enables the integration of sustainability into current state of the curricula at the university to be established. Further, with the advancement of geospatial technology and new visualisation opportunities through the use of the digital twin platform provides capabilities to communicate the outcomes of sustainability and involvement of each faculties and departments more effectively to the university community and wider stakeholders.

The purpose of this paper is to assess consumer motivation and willingness to pay (WTP) for “safer” vegetables from the use of non-treatment options of wastewater use in urban/peri-urban vegetable production.

As a theoretical basis, consumer theory of maximizing utility being an indicator of individual preference was examined through choice experiment (CE) method to measure the WTP for value of safety within the context of health reduced risk (pathogen reduction) of illness. WTP was tested empirically using survey data from 650 households in the two largest cities in Ghana (Accra and Kumasi) that are characterized by a number of well-established vegetable producers who use wastewater in their production and a large urban and peri-urban vegetable consumer market.

Experience of vegetable borne diseases drives the need for safer vegetables and income and gender are key demographic factors influencing WTP. It was further found that consumers are willing to pay an average amount of GH¢ 4.7 ($2.40) per month for a technology change that would result in the production of “safer” vegetables.

Understanding WTP offers insight into consumer concerns, behaviour and their readiness to pay for safer vegetable options. However, a further consideration of the impact of the combinations of the various non-treatment options on pathogen reduction and the assessment of the financial viability of each option will collectively ensure an efficient and cost-effective implementation of the technologies.

WTP insight gained has implications for vegetable production, marketing and public health policy. The understanding from the findings forms a solid basis to canvass for certification system for urban/peri urban vegetables. The information provided also helps to formulate effective public education on the safety of vegetables.

Measuring WTP for safer vegetables by Ghanaian urban/peri-urban consumers is novel. The CE approach is robust and the findings can inform vegetable production and marketing decisions as well as public health policy formulation.
