Over 90% of global yam production is from West Africa where it provides food and income for above 300 million smallholders’ farmers. However, the major challenge of yam is 10–40% post-harvest losses due to the lack of appropriate storage facilities. This paper assesses a biogas-driven cogeneration system, which could supply electricity and cold storage for ‘yam bank’ within a rural community. Considering 200 households’ Nigerian village as a case study, crop residues are used as anaerobic digestion feedstock to produce biogas, which is subsequently used to power an internal combustion engine. Result shows that the system could store 3.6 tonnes of yam tubers each year and provide enough electricity for domestic and commercial activities. At the current electricity tariff of USD0.013·kWh−1 for rural areas, the system is unable to payback during its life span. The proposed USD0.42·kWh−1 by Nigerian Rural Electrification Agency seems good with less than 3 years discounted payback period but brings about extra burden on poor rural households. Based on the income from cold storage, electricity tariff of USD0.105·kWh−1 with an interest rate of 4% is suggested to be reasonable which results in 6.84 years discounted payback period especially considering non-monetary benefits of renewable energy system.

Improve Access

To improve access to affordable, reliable and sustainable energy in rural areas of the global south, off-grid systems using renewable generation and energy storage are often proposed. However, solution design is often technology-driven, with insufficient consideration of social and cultural contexts. This leads to a risk of unintended consequences and inappropriate systems that do not meet local needs. To address this problem, this paper describes the application of a capabilities-led approach to understanding a community’s multi-dimensional energy poverty and assessing their needs as they see them, in order to better design suitable technological interventions. Data were collected in Tlamacazapa, Mexico, through site visits and focus groups with men and women. These revealed the ways in which constrained energy services undermined essential capabilities, including relating to health, safety, relationships and earning a living, and highlighted the specific ways in which improved energy services, such as lighting, cooking and mechanical power could improve capabilities in the specific context of Tlamacazapa. Based on these findings, we propose some potential technological interventions to address these needs. The case study offers an illustration of an assessment method that could be deployed in a variety of contexts to inform the design of appropriate technological interventions.

Post Harvest

This study assessed post-harvest activities and post-harvest losses of green chili farming in Kabjisa, Punakha, Bhutan. Data came from interviewing 75 chili-growers selected via proportionate random sampling. Most farmers were found selling fresh chili (green chili). Few farmers produced blanched, dried, and powdered chilies for self-consumption. Most grown chili varieties were Wookup ema, Indian chili, and Yangtsep ema. Farmers mostly harvested chilies manually during the daytime in a bucket. The majority of the farmers have sorted and graded chilies based on disease infection, damaged parts, and size. Chilies are usually packed and stored for a night before the sale. Most chili losses occurred during harvesting, followed by marketing and sorting. The price of fresh chilies had to discount significantly during the peak season as farmers could not process chilies into other products. Hence, supporting farmers with dryer, cold storage, chili value addition infrastructure, and contract farming would minimize chili losses.

AbstractThe article presents results from a research on the relevance and challenges of collaboration for the long-term sustainability of rural community enterprises. The study relies on Communities of Practice and Degrowth theories. Methods include semi-standardised interviews and focused ethnography in two community enterprises in rural areas in Germany and Portugal. Main results confirm the relevance of collaborative relations with residents, public sector, peer organisations and within the teams for both stability and transformative power of the organisations’ work. Respectful handling of privileges and balance in participation and professionalisation support sustainability, whereas institutional stagnation and involuntary degrowth may risk it.

A ausência de sistemas de tratamento de esgoto doméstico é uma das principais causas de insalubridade e degradação ambiental, além de ser uma forte ameaça à segurança alimentar das famílias rurais brasileiras. O estudo teve como objetivo fornecer subsídios para a elaboração de um programa de implantação de tratamento de esgoto doméstico na área da microbacia hidrográfica do Córrego do Mato, situado na comunidade rural São Braz, Simonésia, Minas Gerais. Foi investigada a situação do abastecimento de água e do esgotamento sanitário de 67 domicílios. Foi encontrado um cenário preocupante em relação à disposição final do esgoto doméstico, sendo que 96% dos domicílios estão em situação inadequada - disposição in natura em cursos d’água ou fossas rudimentares. Foram propostas alternativas adequadas para o tratamento do esgoto doméstico de acordo com as necessidades e condições locais da área de estudo. As alternativas escolhidas são tecnologias sociais e ecológicas com replicação e já implantadas em outras localidades rurais. Palavras-chave: Águas residuárias. Desenvolvimento rural.

Decentralized technologies appropriate for treating domestic sewage in rural areas: case study for a rural community in Simonesia - Minas Gerais Abstract The absence of domestic sewage treatment systems is one of the main causes of unhealthy and environmental degradation, in addition to being a strong threat to the food security of Brazilian rural families. The study aimed to provide subsidies for the elaboration of a program for the implementation of domestic sewage treatment in the area of the watershed of the Córrego do Mato, located in the rural community of São Braz, Simonésia, Minas Gerais. The situation of water supply and sanitation for 67 households was investigated. A worrying scenario was found in relation to the final disposal of domestic sewage, with 96 % of households being in an inadequate situation - in natura disposal in water courses or rudimentary cesspits. Appropriate alternatives have been proposed for the treatment of domestic sewage according to the needs and local conditions of the study area. The alternatives chosen are social and ecological technologies with replication and already implemented in other rural locations. Keywords: Wastewater. Rural development. Hydrographic basin.

Decentralization of industry from urban to suburban and rural areas is a notable current trend. One zone where it is particularly marked is the rapidly expanding "Bay Area" around San Francisco, where a number of planned industrial communities are springing up. This is a first general report of a study being made by a staff and graduate student group at Stanford University of the movement of industry into a semi-rural community within that area. A prime purpose of the study, which will continue over a period of years, is to assess the special contributions the behavioral science field of social anthropology can make to research on industrial community development.
