by Alik Pelman, Jerke W. De Vries, Sigal Tepper, Gidon Eshel, Yohay Carmel, Alon Shepon Providing equitable food security for a growing population while minimizing environmental impacts and enhancing resilience to climate shocks is an ongoing challenge. Here, we quantify the resource intensity, environmental impacts and nutritional output of a small (0.075 ha) low-input subsistence Mediterranean agroecological farm in a developed nation that is based on intercropping and annual crop rotation. The farm provides one individual, the proprietor, with nutritional self-sufficiency (adequate intake o ..read more

by Michał Bączyk, Koen Frenken, Matthijs B. Punt, Iris Wanzenböck This study analyzes the role of international alliances in the adoption of new technology at the national level. We look at the worldwide diffusion of six key infrastructure technologies during the past six decades among 161 countries: nuclear power, solar power, wind power, marine power, high-speed rail, and telecommunication satellites. Acknowledging that international relations are not solely structured by formal alliances, we further investigate the impact of neighboring states on technology diffusion, as neighbors tend to m ..read more

An assessment of policies to promote perennial energy crop and woodland planting
PLOS » Sustainability and Transformation
by Judith S. Ford, Peter G. Taylor
2M ago
by Judith S. Ford, Peter G. Taylor If the UK is to meet its target of reducing greenhouse gas (GHG) emissions to net zero by 2050, significant land-use change will be required. More woodland will have to be created and more perennial energy crops (PECs) will need to be grown. Land will also be required for food production, habitat restoration, and for new settlements. Government intervention will be required if landowners are to deliver this transition in land use. This research identified 43 policies that had been proposed for delivering increased planting of PECs and new woodlands. Their des ..read more

by Haruna Sekabira, Shiferaw Feleke, Victor Manyong, Leonhard Späth, Pius Krütli, Guy Simbeko, Bernard Vanlauwe, Johan Six Achieving the United Nation’s 2030 agenda which aims, among other goals, to ensure sustainable consumption and production patterns, requires a sustainable resource use model deployed at scale across global food systems. A circular bioeconomy (CBE) model of resource use has been proposed to reuse of organic waste in agricultural production to enhance food security. However, despite several initiatives recently introduced towards establishing a CBE in sub-Saharan Africa (SSA ..read more

by Irene S. Fortune, Alethea S. Madgett, Ann Scarborough Bull, Natalie Hicks, Milton S. Love, David M. Paterson Offshore oil and gas platforms (OGP) have been installed worldwide and initially with limited consideration given to the nature of their positive or negative long-term interactions with the natural marine habitats. However, as OGP reach the end of their useful life, with many being decommissioned and removed, it is timely to review the growing evidence of the association of marine biota with OGP to provide a summary and synthesis for policy makers and to give insight to decisions in ..read more

Disposable diaper consumption in sub-Saharan Africa: Estimating the risks of associated unsafe waste

by Mair L. H. Thomas-Possee, Peter J. Shaw, Robert E. S. Bain, Allan G. Hill, Joseph Okotto-Okotto, Lorna G. Okotto, Mawuli Dzodzomenyo, Jim A. Wright Disposable diaper use is widespread in many low- and middle-income countries whilst waste collection services are scarce. Despite the potential environmental and public health impacts of disposable diaper consumption by households lacking waste services, an international system for monitoring such consumption is lacking. This study therefore aims to develop and evaluate a method for estimating disposable diaper use based on secondary data, speci ..read more

Strategic styles of hardware product development could accelerate commercialization in cleantech startups

by Erin Looney, André Buscariolli, Maria C. Yang, Geoffrey Raymond, Tonio Buonassisi, Ian Marius Peters Hardware-based startups risk having longer times-to-market, deterring investment in the clean technologies that are critical to a sustainable future. We interviewed 55 leaders at hardware startups, 20 of which are cleantech, mapped their development timelines, and found prototyping to be the longest development step (median of 19 weeks per prototype) regardless of prototype complexity or iteration. Qualitative interview analysis reveals the prototyping team’s choice of development style is a ..read more

by Jeremy Kohlitz, Melita Grant, Ratan Bahadur Budhathoki, Shova Chhetri, Heman Paneru, Min Prasad Basnet, Sunetra Lala, Gabrielle Halcrow, Naomi Carrard Transformative change in how local governments support rural water services is required to accommodate the increasingly extreme effects of climate change on water service systems. This study explores the potential for contextualised soft systems thinking activities to prepare local government officials with responsibilities pertaining to rural water services in Nepal to shift towards more transformative thinking. First, the study presents the ..read more

To trust or not to trust? Trust landscape of organic animal husbandry: Mapping consumer attitudes and information demands in Germany
PLOS » Sustainability and Transformation
by Elisa Bayer, Sarah Kühl
5M ago
by Elisa Bayer, Sarah Kühl A mainly positive attitude of consumers towards organic animal husbandry with its higher keeping standards compared to the legal regulations is evident. However, less is known about consumers’ detailed expectations of organic husbandry and in particular their attitude and trust along the value chain of organic animal products. Which consumers trust the most, and how do they want to be informed about organic animal husbandry? Where along the chain are trust deficits that should be addressed in the future to support sustainable food consumption with high animal welfare ..read more

5M ago
by Ipsita Das, Leonard le Roux, Richard Mulwa, Remidius Ruhinduka, Marc Jeuland Nearly 2.3 billion people lack access to clean cooking fuels and technologies worldwide, representing a critical failure to achieve SDG7’s cooking energy access goal. In Sub-Saharan Africa, dependence on polluting cooking fuels is particularly high, resulting in considerable environmental, health, and time-related costs. Progress in the region has been greatest in urban areas, partly because incomes are higher and alternative fuels more widely available than in rural areas, but understanding of the dynamics of urba ..read more
