Challenges and Opportunities for Sustainable Urban Farming in South African Low-Income Settlements: A Case Study in Durban

Growing urban centres have been attracting ever higher numbers of rural migrants, including small-scale farmers, looking for better opportunities due to the rise of large-scale farming, loss of land and climate change. Consequently, there has been an increase in the number of spontaneous and informal settlements being constructed as cities do not keep up with the planning and infrastructure development for new arrivals. Urban dwellers in informal, unplanned settlements where issues of land tenure and access to services are prevalent have, consequently, been exposed to precarious living conditions with limited access to food and water scarcity. Urban agriculture (UA) strategies have been adopted by those residents to alleviate poverty and food insecurity, and have been seen to perform other functions, such as environmental, social, cultural and developmental. This study explores challenges and opportunities for sustainable urban farming as an integrated environmental management strategy for the upgrading of informal settlements in three case studies in Durban. This paper demonstrates the need for municipalities to support community driven processes to ensure sustainability of UA initiatives and sustained investment for maintenance. Policy makers need to create an enabling environment for academics, non-governmental organizations (NGOs) and the private sector to co-develop water efficient solutions to manage the food-water nexus and capitalise on localised community structures and groups, such as co-operatives and women groups.</jats:p

The potential of performance targets (imihigo) as drivers of energy planning and extending access to off‐grid energy in rural Rwanda

Rwanda has one of the lowest electrification rates in Sub‐Saharan Africa and ambitious targets of boosting energy access, with an encouraged private sector involvement. However, barriers such as end‐user awareness and participation in policy and business model design prohibit the pace of rural electrification. A case of Rwanda is analyzed, pointing to the potential of the imihigo (performance contracts) framework. Given the adoption of household‐level performance contracts, which can include energy access, it is proposed they could drive local participation among off‐grid communities. Results of a survey with 218 users of Solar Home Systems in North‐Western Rwanda and from five focus groups show that village‐level energy targets impact on the prioritization of energy target setting among households. Including off‐grid energy options in the imihigo booklets distributed to households could influence awareness raising and allow private sector providers to act in a more targeted way, prioritizing areas with most prevalent energy targets. Additionally, community meetings (umuganda) tied to imihigo offer participatory spaces for information and feedback sharing. These will assist in the design of energy planning and business models, which best fit local needs and respond to the challenges faced by the energy poor

Barriers and opportunities for participatory environmental upgrading: Case study of Havelock informal settlement, Durban

Urbanisation is one of the key challenges of this decade with 68% of the global population likely to be living in urban areas by 2050. This challenge is particularly acute in sub-Saharan Africa where future towns and cities will see an influx of residents living in spontaneous human settlements. As cities struggle to keep up with the speed of growth and spread of informal settlements, associated environmental challenges such as air and water pollution and waste management have been significantly increasing posing a health risk in high density settings. Using the case of Havelock informal settlement in Durban, the authors identified key challenges associated with poor environmental conditions, lack of basic infrastructure, and the implications for settlement upgrading. The study uses mixed methods combining transect walks, priority mapping, seasonal calendar, focus group discussions and household interviews to explore the households' most challenging environmental issues faced daily by informal dwellers. This paper seeks to make the case for targeted participatory environmental infrastructure and management delivery in urban settlements in South Africa. The research also highlights the value of adopting a holistic approach to infrastructure provision to effectively enhance the living conditions of communities. Targeted participatory processes are vital to ensure that holistic infrastructure interventions are acceptable, appropriate and embedded in local communities to create sustainable habitats

Integrating psychosocial and WASH school interventions to build disaster resilience

This paper reviews the key disaster risk management (DRM) frameworks used for protecting children's wellbeing in disaster settings and identifies a lack of consideration for (1) psychosocial and (2) water, sanitation and hygiene (WASH) needs. It also demonstrates that these two domains are meaningfully linked, as access to adequate WASH provision may protect psychosocial wellbeing and promote community resilience. As support in both domains is vitally important to children's wellbeing, these gaps warrant immediate attention. Schools are uniquely situated to support these needs as part of disaster risk management and resilience building. Therefore, we consider the ASEAN Common Framework for Comprehensive School Safety (ACFCSS), which is an adaptation of the Comprehensive School Safety Framework (CSS) implemented in schools across the ASEAN region. While the CSS explicitly considers WASH, it only briefly considers psychosocial support; the ACFCCS lacks consideration of both domains. We argue revisions of the ACFCSS should prioritise the inclusion of psychosocial and WASH support and consider the role of schools beyond their capacity as educational institutions. We present an adaptation of ACFCSS with an additional framework pillar to guide this revision. Overall, we advocate for an integrated approach to DRM in schools based on an evidence-based, interdisciplinary perspective. We provide a series of evidence-based recommendations for DRM frameworks to consider, especially for those that intend to safeguard the wellbeing of children

Lost learnings: Breaking the silence of failure in the energy and development sector

It is often said that in order to succeed, one most fail and yet, all too often, we fail to talk about failure. This is particularly true in energy and development (E&D), a sector that faces complex challenges leading to relatively high chances of project failure. This paper explores failure in E&D, specifically how it is discussed, its impact and mechanisms encourage discussion of failure. This was achieved through a review of academic literature, workshops and informal interviews, and is the first study to holistically examine the important topic of failure in E&D. The results show that failure is complex and linked to multiple factors. There is an important distinction to be made between “productive failures”, where new learnings are assimilated and shared, and “unproductive failures”, where this does not happen. Although failed projects consume scarce resources, reduce the productivity of the sector and increase the perceived risk of future projects, we argue that failure is a necessary part of experimentation and risk taking that generates new knowledge and important learnings. Changes to the nature of funding in the sector, compulsory project or research registration, open-source reporting on productive failure and networks that provide safe spaces for peer-to-peer learning could improve openness about failure. These mechanisms could increase the likelihood of future project success and accelerate progress towards Sustainable Development Goal 7

Scalable off-grid energy services enabled by IoT: A case study of BBOXX SMART Solar

This case study intends to show how Internet of Things (IoT) technology can be used to tackle development challenges by using the case study of BBOXX- a Solar Home Systems provider operating in South-Western Kenya and across Rwanda, and its SMART Solar platform applied to nearly 20,000 currently active systems. It aims to highlight the benefits of such technology to its users and how it can be utilised to create scalable business models for energy access through improved customer understanding. However, it also shows the difficulties in designing, developing and deploying appropriate technologies in an affordable and impactful way. Similar applications in the water sector are briefly looked at to further explore the potential and the challenges of IoT technologies in driving social and economic development. The case study raises ethical questions about the storage, collection and sharing of data and explores whether the data protection models prevalent in the developed world are applicable in a development context. It offers ideas for future research and policy recommendations, pointing to the need of including financial, socio-economic and ethical considerations in the processes of innovative solutions development

СОВЕРШЕНСТВОВАНИЕ ОБСЛЕДОВАНИЯ ЗРИТЕЛЬНОГО АНАЛИЗАТОРА ПРИ РАССЕЯННОМ СКЛЕРОЗЕ

137 (274 eyes) relapsing-remitting multiple sclerosis patients have been given detailed neuroophthalmologic examination. 58 of these patients (74 eyes) had a previous history of optic neuritis. As a result, the most informative methods of examination have been identified. These include the estimation of the frequency characteristics of the vision (vizokontrastoperimetriya, low-contrast tests Sloan), standard static automated perimetry, pattern visual evoked potentials, and optical coherence tomography which is used to measure macular volumes and retinal nerve fiber layer thickness. The above – mentioned methods make it possible to reveal the involvement of the optic analyzer in the inflammatory and neurodegenerative process at the pre-clinical stage. The obtained results allow us to recommend inclusion of the methods in the standard algorithm for the examination of patients with probable multiple sclerosis. Проведено детальное нейроофтальмологическое обследование 137 пациентов с рецидивирующеремиттирующей формой рассеянного склероза (274 глаза). Из них 58 пациентов (74 глаза) имели в анамнезе оптический неврит. Были определены наиболее информативные методы обследования, позволяющие еще на доклинической стадии выявить вовлечение зрительного анализатора в воспалительный и нейродегенеративный процессы: оценка частотных характеристик органа зрения (визоконтрастопериметрия, низкоконтрастные таблицы Слоан), статическая автоматизированная периметрия, зрительные вызванные потенциалы на шахматный паттерн, оптическая когерентная томография для определения толщины слоя нервных волокон сетчатки. Полученные результаты позволяют рекомендовать их включение в стандартный алгоритм обследования больных с вероятным рассеянным склерозом.

Mapping synergies and trade-offs between energy and the Sustainable Development Goals

The 2030 Agenda for Sustainable Development—including 17 interconnected Sustainable Development Goals (SDGs) and 169 targets—is a global plan of action for people, planet and prosperity. SDG7 calls for action to ensure access to affordable, reliable, sustainable and modern energy for all. Here we characterize synergies and trade-offs between efforts to achieve SDG7 and delivery of the 2030 Agenda as a whole. We identify 113 targets requiring actions to change energy systems, and published evidence of relationships between 143 targets (143 synergies, 65 trade-offs) and efforts to achieve SDG7. Synergies and trade-offs exist in three key domains, where decisions about SDG7 affect humanity’s ability to: realize aspirations of greater welfare and well-being; build physical and social infrastructures for sustainable development; and achieve sustainable management of the natural environment. There is an urgent need to better organize, connect and extend this evidence, to help all actors work together to achieve sustainable development. On 5 September 2015, the 193 members states of the United Nations (UN) adopted a new 2030 Agenda for Sustainable Development. The 2030 Agenda succeeds the UN’s Millennium Development Goals (MDGs), and features 17 Sustainable Development Goals (SDGs) with 169 targets, which UN member states have committed to implement by 2030. Energy was not explicitly referred to in the MDGs, and came to be referred to as the ‘missing’ MDG. During the operational period of the MDGs and negotiation of the 2030 Agenda, it was increasingly recognized that energy underpins economic and social development, without which it would not be possible to eliminate poverty. This change in status made sustainable energy provision and access one of the central themes of the 2030 Agenda, whose preamble calls for “universal access to affordable, reliable and sustainable energy” and recognizes that “social and economic development depends of the sustainable management of our planet’s natural resources”. SDG7 is accompanied by five targets to be achieved by 2030: ensure universal access to affordable, reliable and modern energy services (7.1); increase the share of renewable energy in the global energy mix (7.2); double the global rate of improvement in energy efficiency (7.3); enhance international cooperation to facilitate access to clean energy research and technology (7.a), and promote investment in energy infrastructure and clean energy technology (7.b). By understanding the complex links between the SDGs and their constituent targets, researchers can better support policymakers to think systematically about interactions between the different SDGs, including how actions to achieve each goal affect each other within and between sectors. Studies to date have lacked a target-level approach or have focussed on only a few of the SDGs. Here we present a formative attempt by an interdisciplinary group of researchers to identify the full range of goals and targets in the 2030 Agenda that call for changes in energy systems, and characterize evidence of synergies or trade-offs between delivery of each of the 169 targets and efforts focussed on pursuit of SDG7 and each of its constituent targets. The purpose of this Perspective is not to provide definitive answers. Instead we aim to lay a foundation for systematic (and context-specific) exploration of the interlinkages between each of the SDG targets, in the context of decision-making about development and the transformation of energy systems

Neuroimaging in anxiety disorders

Neuroimaging studies have gained increasing importance in validating neurobiological network hypotheses for anxiety disorders. Functional imaging procedures and radioligand binding studies in healthy subjects and in patients with anxiety disorders provide growing evidence of the existence of a complex anxiety network, including limbic, brainstem, temporal, and prefrontal cortical regions. Obviously, “normal anxiety” does not equal “pathological anxiety” although many phenomena are evident in healthy subjects, however to a lower extent. Differential effects of distinct brain regions and lateralization phenomena in different anxiety disorders are mentioned. An overview of neuroimaging investigations in anxiety disorders is given after a brief summary of results from healthy volunteers. Concluding implications for future research are made by the authors

Non-nociceptive roles of opioids in the CNS: opioids' effects on neurogenesis, learning, memory and affect.

Mortality due to opioid use has grown to the point where, for the first time in history, opioid-related deaths exceed those caused by car accidents in many states in the United States. Changes in the prescribing of opioids for pain and the illicit use of fentanyl (and derivatives) have contributed to the current epidemic. Less known is the impact of opioids on hippocampal neurogenesis, the functional manipulation of which may improve the deleterious effects of opioid use. We provide new insights into how the dysregulation of neurogenesis by opioids can modify learning and affect, mood and emotions, processes that have been well accepted to motivate addictive behaviours
