There is a scarcity of fresh water in many rural communities where solar stills can be used to produce drinking water at a minimal cost. These stills use solar energy, which is a sustainable form of energy, and hence this can contribute towards achievement of United Nations (UN) Sustainable Development Goals (SDG). This study aims to develop empirical models of a solar stills based on experimental data obtained at Werrington South, New South Wales, Australia. Two solar stills were used in the experiment, a conventional design (Con-Still) and a con-still modified with adding extra thermal mass inside the still (mod-still). Regression analysis was adopted to develop prediction equations using Pi (productivity in L/m2/day) as the response variable and ambient temperature (Ta), sky temperature (Ts19), global radiation (Gh), and wind velocity (W) as the predictor variables. The mean and median productivity values of the mod-still were found to be 17%, and 22% higher than that those for the con-still. The proposed mod-still can be further improved and used in rural areas to produce fresh water from sea water and other forms of contaminated water.

In a context of political and economic austerity, social innovation has been presented as a solution to many social challenges, old and new. It aims to support the introduction of new ideas in response to the current urgent needs and challenges of vulnerable groups and seems to offer promising solutions to the challenges faced by rural areas. Yet the evidence base of the impacts on the sustainable development of rural communities remains scarce. In this paper, we explore social innovation in the context of community forestry and provide a brief synthetic review of key themes linking the two concepts. We examine a case of social innovation in the context of community forestry and analyse its type, extent, and scale of impact in a marginalized rural area of Scotland. Using an in-depth case study approach, we apply a mixed research methodology using quantitative indicators of impact as well as qualitative data. Our results show that social innovation reinforces the social dimension of community forestry. Impacts are highlighted across domains (environmental, social, economic, and institutional/governance) but are mainly limited to local territory. We discuss the significance of those results in the context of community forestry as well as for local development. We formulate policy recommendations to foster and sustain social innovation in rural areas.

Mobile ICTs have addressed the digital divides between the global south and the global north. While a phenomenal mobile penetration in developing countries has enabled ICT4D innovations by connecting previously unconnected people, several communities suffer adverse inclusion or lack access altogether. Such digital divides within countries have been attributed to technical, social, and economic issues. As a result, many approaches to bridging the digital divides have been used by both academics and practitioners. This chapter, therefore, discusses the potential use of community networks for providing sustainable and affordable access to rural communities in developing countries. In addition to the advantages of community networks, the chapter presents the challenges thereof, and it contributes to the vexed question about how to harness ICTs to empower the disadvantaged communities in developing countries. A case study of Zenzeleni Makhosi community network in South Africa's Eastern Cape province is presented and analysed using Sen's capability approach.

There has been increasing recognition that for regional competitiveness in rural areas there needs to be a focus on sustainable farming initiatives especially for family farms that are competing with global conglomerates. Family farms, whilst declining in number, are the purpose of this paper studying the rural entrepreneurship in family farms as they are at the heart of rural communities and the overall agricultural industry and comprise a high percentage of total farms. This paper takes a case study approach using in-depth semi structured interviews to delve into the types of entrepreneurial strategies that are distinctive of family farms in terms of their sustainability approach to farming. Dairy farms in the West Victorian area of Australia are studied and the findings suggest that family farms can increase their regional competitiveness and international standing by focusing on their collaborative, social and sustainable entrepreneurial strategies.

Taking tourism in Namibian rural areas as an empirical case study, this paper analyses the main factors that explain the economic outcome in a negotiation process in which local communities and private operators bargain over the distribution of income generated through a partnership lodge. While much research has focused on the required preconditions (especially property rights) and efficiency effects of tourism partnerships, a Nash bargaining model allows us to assess the distributive effects of such contracts. In particular, variables such as insecure community land tenure, and the resulting reduced value of land, the remoteness of lodges and the community's impatience and attitude towards risk could explain why rural communities have not so far captured the lion's share from tourism activities in communal lands. Finally, the paper shows that future research will be needed to complete the model in order to provide an account of the contractual problems that limit the efficiency of tourism partnerships in rural areas – transaction costs and underinvestment.

This research presents a conceptual model to illustrate how people living in rural areas can harness bioenergy to create beneficial ‘community-driven’ income-generating activities. The research is contextualised within the rural developing areas of Bangladesh where people live in abject poverty and energy deficiency. The research methodology applied in this study aims to determine the basic requirements for implementing community-based anaerobic digestion (AD) facilities and illustrate how an AD facility positively impacts upon the lives of rural communities directly after its installation. The survey results demonstrate that implementing a biogas plant can save 1 h and 43 min of worktime per day for a rural family where women are generally expected to for cook (by the long-term tradition). In addition to the positive impacts on health and climate change through adoption of clean energy generation, this time saving could be utilised to improve women′s and children’s education. The research concludes that, by providing easy access to clean bioenergy, AD can change people’s quality of life, yielding major social, economic and environmental transformations; key benefits include: extending the working day; empowering women; reducing indoor air pollution; and improving people’s health and welfare. Each of these tangible benefits can positively contribute towards achievement of the UN’s Sustainable Development Goals. This work demonstrates the potential to increase the implementation of AD systems in other developing world countries that have similar geographic and socioeconomic conditions.

Background: The year 2017 marked the 21st anniversary of the South African Cuban Medical Collaboration (SACMC) programme that offers disadvantaged South African (SA) students an opportunity for medical training in Cuba. Graduates are expected to return to practice at a primary care level in rural communities; however, little is known about the professional trajectories and career choices of graduates from the programme.Aim: This study explored the reasons why students enrolled in the programme, their professional and career choices as graduates and their career intentions.Setting: The study setting was the whole of SA although participants were primarily drawn from KwaZulu-Natal.Methods: An exploratory, qualitative case study used a purposive sampling strategy to gather data through semi-structured interviews from participants.Results: Graduates (N = 20) of the SACMC programme were all practicing in local SA settings. Participants preferred the SACMC programme as it offered them a full scholarship for medical training. Nineteen doctors had fulfilled their obligation to work in rural areas. Thirteen doctors are engaged in primary healthcare practice, either as private practice generalists or as public service medical officers. Three doctors had completed specialty training: one doctor was training towards specialisation, one doctor was employed at national government and two doctors were employed as medical managers. At the time of the study, 11 doctors were practicing in rural locations and 19 had indicated a long-term intention to work and live within South Africa.Conclusion: The participants of this study who graduated from the SACMC programme are fulfilling their obligations in rural communities. They all intend to contribute to the SA medical workforce in the long-term.

The paper proves that sweeping digital transformations are a global trend in agri-food development. Significantly improved economic efficiency, rational use of natural resources, operational exchange of relevant information, new markets, and economic opportunities under modern climate change are possible owing to digital transformations. It is grounded that the elimination of world hunger based on the provided internal food security and secured rural communities should be the primary goal of the digital innovations in agri-food systems within Sustainable Development Goals (SDGs). The paper states that along with the significant benefits of digital technologies, the great destructive impact on the overall societal development is possible due to the corporate monopolization of digital processes. Thus, there is the risk of the development of food systems, which are characterized by decreasing in the food supply, loss of biodiversity and rural livelihoods. Proposals to mitigate the threats of digitalization, strengthen internal food security and enhance the development of rural communities through information and communication technologies (ICT) are substantiated. The specific of the agri-food digitalization in Ukraine is outlined, which is determined by the duality of the organizational structure of agriculture (corporate and individual sector) with a tendency to the concentration of land, power, and financial resources in favor of corporations expanding opportunities for digitalization. Appropriate safety measures to mitigate the negative impact on the development of small producers, rural areas, and Ukrainian society are identified.

<p><em>Poverty often occurs in rural areas rather than urban areas, low education which results in low quality of human resources and lack of access is often the cause of rural poverty. In addition, most of the economies of rural communities rely solely on the traditional agricultural sector. Various poverty reduction policies have been implemented, including village fund policies. This study aims to examine the management of village funds in the Balong sub-district of Madiun Regency with a case study in the villages of Tatung and Karangmojo villages covering the management of village funds in Tatung village and Karangmojo village. Balong Subdistrict and the impact of empowerment in the villages of Tatung and Karangmojo, Balong District. This research was conducted in Balong Subdistrict, Ponorogo Regency with a Case study in Tatung Village and Karangmojo Village with qualitative methods. In the village of Tatung village funds are managed as tourist villages with a focus on Paragliding tourist rides. Whereas in Karangmojo village it is used for Bumdes in the form of Lovebird birds, providing Gapoktan assistance, and infrastructure development.</em></p>
