Rice cultivation is the main economic livelihood for many families around the world. This activity represents several challenges for farmers and community members for rural sustainability, a cross-cutting element of the Sustainable Development Goals (SDGs) of the United Nations (UN). In response, the Polytechnic University (ESPOL), fulfilling its mission of linking with society, implemented a community program where students and professors interact and collaborate with rice farmers in the rural community of Paipayales, located in the Santa Lucia canton, Guayas province. This article explores the impact of university-community projects through the Participatory Action Research (PAR) approach in order to evaluate them as a tool for contributing towards rural sustainability in communities. As a result, it was determined that the main problems faced by most of the farmers of the “Dios con Nosotros” Association are the availability of water in the wells and the commercialization of paddy rice. Considering these problems, the wells were geolocated and a board was designed for proper water management; at the same time, water quality was studied and recommendations were presented according to the problems encountered. Two proposals were also presented to create a rice husker and a rice separator to increase their profit margin by selling rice directly to retailers and wholesalers. As relevant conclusions, the importance of implementing links and relationships between the university community and society was highlighted, guaranteeing the value of working in transdisciplinary teams and achieving a comprehensive intervention that would lead to significant improvements in the community.

Energy production, supply and consumption are global issue with many economic, environmental and social implications. Mentioned issue is even more expressed in remote rural areas, in particular in developing countries, as are the countries of the Western Balkans (WB). Renewable energy sources (RES) could represent optimal energy alternative for sustainable performing of agricultural and other activities, as well as for improving the current state of living conditions in rural communities. The main goal of research is to mark the most suitable RES alternative (six alternatives) for wider implementation in rural space of WB. The applied methodology framework implies experts’ opinion (engagement of eight experts) and the use of multi-criteria decision-making methods (MCDM), (specifically fuzzy-rough LMWA and fuzzy-rough CRADIS methods) under the predefined criteria (nine criteria). Derived results show that the implementation of the solar energy plants could play an optimal solution, while as the relatively unsuitable alternative could be marked the use of energy potential of watercourses. Gained final result, i.e. ranking order of the considered alternatives is additionally verified by the appliance of other MCDM methods, while the sensitivity analysis was also performed.

Human capital development is increasingly gaining policy relevance especially with the implementation of the Sustainable Development Goals (SDGs). This study examined the correlates of human capital expenditure in rural Nigeria. General Household Survey dataset collected by the National Bureau of Statistics was used for this study. Descriptive statistical tools, principal components analysis and the Heckman selection model were used to analyse relevant data. The study found majority of the households were maleheaded, with an average size of 7 people. In terms of access to education, 62.1% of the surveyed households had access to education and spent an average of NGN 12,570.56 on education. The age of household head, access to loans, marital status and household size were the correlates of human capital expenditure in rural Nigeria. Also, school fees and registration accounted for 41.2% of households’ expenditure on education. The study found paucity of funds, low priority placed on education and low interest were the main constraints to human capital expenditure. The study recommended the design and implementation of pro-poor educational interventions especially for children from rural households. Also, there is the need for government, multilateral organisations and financial institutions to position rural households for financial inclusion.

This study examined the livelihood strategies and food security situation of rural households around Derba Cement Factory by taking a randomly selected sample of 215 heads of farm households from three rural kebeles. A mixed research approach was employed to triangulate concurrently collected data through household survey, key informant interviews and focus group discussions. Informed by the sustainable rural livelihood framework, descriptive statistics were used to describe rural households’ livelihood strategies and challenges they faced while inferential statistics was employed to explain households’ food security situations with different livelihood combinations. While mixed farming was found to be the mainstay of the household economy, small-scale irrigation and extracting forest products were also used as supplementary economic activities. More than a half of the respondents (52.5%) reported at least one non-farm activity. Land shortage was identified as a major constraint to expand crop production and this was further aggravated by the activities (e.g. querying leading to displacement) of the Derba Cement Factory. This further affected household labour allocation and natural resources utilization. The result of household food (in) security access scale indicated that 59% of the respondents have experienced food access insecurity in 2016. However, respondents who combined agriculture and non-farm activities appeared relatively more food secure than those engaged in agriculture alone or in non-farm activity only. Overall, households with multiple livelihood strategies had diverse food entitlements to maintain sustainable food consumption. Yet, necessity induced diversification was found to affect food access security of households. This calls for inclusive policies and strategies that integrate rural non-farm activities to subsistence farming in order to assure sustainable livelihood in rural communities.

Rural households are displaced from their lands without any plan in place to resettle or compensate them, for a promise of improvement in their living standards. This has not only resulted in a decline in the living standard of the rural populace, in terms of loss of land and livelihoods, the poor are also further marginalized and impoverished. This study examines the welfare implication of domestic land grabs among rural households in Delta State, Nigeria, employing primary data obtained from one hundred and seventy-three representative farming households. Descriptive analysis revealed that majority were low-income earners and engaged in farming as their major occupation. Econometric analysis revealed land size, secondary education, community leaders’ influence, compensation and the use to which the grabbed land was put into as some of the significant factors influencing domestic land grabs in the study area. Further, the size of land grabbed, no compensation for the use of land and low farm output were found to have negative effects on the welfare of the farmers. Thus, the need to intensify efforts to ensure that the rural populace is not being unreasonably dispossessed of its lands, becomes imperative. The need for commensurate compensation of rural households whose lands were grabbed and periodical checks on community leaders who positively influence domestic land acquisitions arbitrarily also becomes pertinent for improvement in the welfare of the farmers. This is especially so, if these small-scale farmers are to be significant drivers of global food security.

As the use cases for rural unmanned aerial vehicle (UAV) missions are evolving, the next step is to make on-site UAV missions controlled over long distances. The control is called Beyond visual line of sight (BVLOS) and there is a great need for use cases to become autonomous or self-sustaining over long distances. Designing airspace to include autonomous and BVLOS UAV involves proposals for traffic that do not exist to date, different actors, and a multitude of risks; system design must answer a wide range of questions before its release. Luckily, most of the technical questions are already solved, most of the safety regulations are there in place in general aviation, and the industry is waiting for a new type of transportation. In this paper, the authors propose action for policymakers on how to approach the challenge of developing UAV Traffic Management (UTM) systems that can be applied to any geographic location and identify missing links in decision-making to enable development.
