New Challenges in Underprivileged Regions Call for People-Centered Research for Development

The need for enhancing food production and availability in underprivileged regions of the world requires the attention of scientists. This article explores the possibilities for rethinking agricultural research for development (R4D) in the light of new challenges characterized by a high degree of scientific uncertainty along with associated intense political differences of interest. New challenges that particularly influence food production in underprivileged regions include global climate change, globalization of food chains, and emerging low-carbon energy systems. We argue that by applying the people-centered sustainable livelihoods approach as a research paradigm in R4D, researchers may be more successful in producing knowledge that is useful to entrepreneurial smallholder farmers. Without such rethinking, traditional scientific approaches and logic may limit the contribution that agricultural R4D can make toward the achievement of the Millennium Development Goals of halving extreme hunger by 2015 and improving the livelihoods of all

Significance of Brettanomyces and Dekkera during Winemaking: A Synoptic Review

Wine comprises a complex microbial ecology of opportunistic microorganisms, some of which could potentially inducespoilage and result in consequent economic losses under uncontrolled conditions. Yeasts of the genus Brettanomyces,or its teleomorph Dekkera, have been indicated to affect the chemical composition of the must and wine by producingvarious metabolites that are detrimental to the organoleptic properties of the final product. These yeasts can persistthroughout the harsh winemaking process and have in recent years become a major oenological concern worldwide.This literature review summarises the main research focus areas on yeasts of the genera Brettanomyces and Dekkerain wine. Specific attention is given to the spoilage compounds produced, the methods of detection and isolation fromthe winemaking environment and the factors for controlling and managing Brettanomyces spoilage

A quality improvement programme in radiotherapy using workflow audits

Background. Evaluation of the quality of healthcare depends on measures of structures, processes and outcomes. Progress in recording data allows for better measures of processes, such as the completeness of clinical data, the performance of professional tasks and the use of checklists.Objectives. To report the results of a radiotherapy (RT) workflow audit and a subsequent online survey of user experience.Methods. The RT workflow audit was developed in 2016 and has been undertaken twice a year at 28 facilities or units, with a total of 32 linear accelerators. Electronic patient folders were reviewed to assess the documentation of 90 task items, of which 64 were scored. The auditor came from another facility. The online survey took place in July 2020. It contained questions on the audit’s process, professional value and future use. Invitations were sent by email to the 151 radiotherapist staff at the 28 units where the audit had been implemented. Responses were anonymous.Results. For the RT workflow audit, scores improved from 60% in some units in 2016 to >90% in all units for at least 2 years since 2018. The number of responders to the online survey was 58, giving a responder rate of 38%. The margin of error of the results was 10%. The audit’s task items were considered appropriate by 77% of responders, and feedback was reported by 78% of them. The audit was considered very or extremely valuable to their unit’s service delivery by 58% of responders. Changes in the unit as a result of the audit were reported by 77% of responders. The audit was very useful or extremely useful to 75% of responders in maintaining personal professional standards. The proportion of responders who were very or extremely supportive of continuing with the audit was 77%. The comments in the online survey will be helpful for ongoing review of the RT workflow audit.Conclusions. The RT workflow audit extends the scope of accreditation audits by including measures of processes. Users of the audit evaluate its processes favourably and report that it has value both in their unit’s clinical service and for their personal professional standards. The audit is effective in developing quality improvement programmes

Monetary valuation of salinity impacts and microbial pollution in the Olifants Water Management Area, South Africa

This paper estimates costs associated with water pollution in the Olifants River Water Management Area (WMA) in South Africa, and, more specifically, the area represented by the Loskop Dam Water User Association. We focus on the impacts of salinisation on commercial irrigated agriculture, and of microbial pollution on the general population of the WMA, many of whom do not have access to municipal water and sanitation services, leaving them vulnerable to microbial pollution inthe water resource. Costs associated with salinity are estimates based on the impacts of increased salinity on the value of marginal product of certain irrigated crops. Costs associated with microbial pollution are estimated based on the direct and indirect costs of human health impacts as a result of microbial pollution in the study area. These monetary value estimates give an indication of the magnitude of the cost of water pollution to society in the WMA. It is concluded that the once-off cost required to provide some pollution prevention infrastructure will be lower than the current annual cost burden of pollution on society in the WMA, and that pollution prevention is therefore cost effective

Recommendations for Haemodynamic and Neurological Monitoring in Repair of Acute Type A Aortic Dissection

During treatment of acute type A aortic dissection there is potential for both pre- and intra-operative malperfusion. There are a number of monitoring strategies that may allow for earlier detection of potentially catastrophic malperfusion (particularly cerebral malperfusion) phenomena available for the anaesthetist and surgeon. This review article sets out to discuss the benefits of the current standard monitoring techniques available as well as desirable/experimental techniques which may serve as adjuncts in the monitoring of these complex patients

Food Waste Within South Africa and Saudi Arabia

The food waste reduction potential within the countries of the Middle East and Africa is large and understudied. Countries in the region are faced with food security and sovereignty issues, with over 50% of food imported in some countries. Due to the many differences in this region, this chapter highlights the state of food waste in two prominent countries: South Africa and Saudi Arabia. Both South Africa and Saudi Arabia have their own food waste challenges and solutions. This chapter summarises the current state of food waste research in each country, and reports the estimated volumes of food waste in South Africa and Saudi Arabia along with any notable policy developments

Primary health care facility infrastructure and services and the nutritional status of children 0 to 71 months old and their caregivers attending these facilities in four rural districts in the Eastern Cape and KwaZulu-Natal provinces, South Africa

Objective: To assess primary health care (PHC) facility infrastructure and services, and the nutritional status of 0 to 71-month-old children and their caregivers attending PHC facilities in the Eastern Cape (EC) and KwaZulu-Natal (KZN) provinces in South Africa. Design: Cross-sectional survey. Setting: Rural districts in the EC (OR Tambo and Alfred Nzo) and KZN (Umkhanyakude and Zululand). Subjects: PHC facilities and nurses (EC: n = 20; KZN: n = 20), and 0 to 71-month-old children and their caregivers (EC: n = 994; KZN: n = 992). Methods: Structured interviewer-administered questionnaires and anthropometric survey. Results: Of the 40 PHC facilities, 14 had been built or renovated after 1994. The PHC facilities had access to the following: safe drinking water (EC: 20%; KZN: 25%); electricity (EC: 45%; KZN: 85%); flush toilets (EC: 40%; KZN: 75%); and operational telephones (EC: 20%; KZN: 5%). According to more than 80% of the nurses, problems with basic resources and existing cultural practices influenced the quality of services. Home births were common (EC: 41%; KZN: 25%). Social grants were reported as a main source of income (EC: 33%; KZN: 28%). Few households reported that they had enough food at all times (EC: 15%; KZN: 7%). The reported prevalence of diarrhoea was high (EC: 34%; KZN: 38%). Undernutrition in 0 to younger than 6 month-olds was low; thereafter, however, stunting in children aged 6 to 59 months (EC: 22%; KZN: 24%) and 60 to 71 months (EC: 26%; KZN: 31%) was medium to high. Overweight and obese adults (EC: 49%; KZN: 42%) coexisted. Conclusion: Problems regarding infrastructure, basic resources and services adversely affected PHC service delivery and the well-being of rural people, and therefore need urgent attention.Keywords: primary health care facilities; nutritional status; children; caregivers’ rural; South Afric

Market Integration Shape Organic Farmers’ Organisation

Increasing consumption of organic products in globalised food chains will require the involvement of thousands more smallholder farmers in many regions of the world. A study of Egypt, China and Uganda identified the three key factors of property rights regimes, cultural differences and social organisation as determents of the supply chain organization and farmers’ degree of direct integration in the export markets. Patterns are emerging where smallholder farmers are being socially and economically linked to larger farmers who may do some processing before the raw materials are handed over to the contracting company. Where transactions costs are high, local communities may develop and contract out the land directly to exporting companies who farm using employees. Four organisational patterns are identified which each leads to different types of livelihood benefits for the producers; preliminary results indicate that income and a reliable market access is the dominant benefits

African leafy vegetables in South Africa

In this article the term ‘African leafy vegetables’ was adopted to refer to the collective of plant species which are used as leafy vegetables and which are referred to as morogo or imifino by African people in South Africa. Function is central in this indigenous concept, which is subject to spatial and temporal variability in terms of plant species that are included as a result of diversity in ecology, culinary repertoire and change over time. As a result, the concept embraces indigenous, indigenised and recently introduced leafy vegetable species but this article is concerned mainly with the indigenous and indigenised species. In South Africa, the collection of these two types of leafy vegetables from the wild, or from cultivated fields where some of them grow as weeds, has a long history that has been intimately linked to women and their traditional livelihood tasks. Among poor people in remote rural areas the use of these types of leafy vegetables is still common but nationwide there is evidence of decline, particularly in urban areas. Cultivation of indigenous or indigenised leafy vegetables is restricted to a narrow group of primarily indigenised species in South Africa. Seven groups of indigenous or indigenised African leafy vegetables that are important in South Africa were given special attention and their local nomenclature, ecology, use and cultivation are discussed.Keywords: African leafy vegetables, morogo, imifino, history, ecology, gender, collection, cultivation, use, processing, storag
