The informal sector in the labour reserve economies of Southern Africa with special reference to Zimbabwe

This paper is written as a contribution to the research project in Zimbabwe on the informal sector. We have therefore written it in the absence of any detailed research on the subject. Our main purpose has been to raise both theoretical and policy issues we consider relevant to Zimbabwe. Although experiences elsewhere in the Third World may be useful to Zimbabwe, we have deliberately sought to narrow down the set of relevant experiences by highlighting the specificities of the historical experiences of the type of economies that Zimbabwe belongs to. A number of positions adopted in the paper may have to be rethought in light of more information. Hopefully the assertive and at times polemical way in which they have been stated will provoke response from other researchers and enhance our understanding of the informal sector in this country. Furthermore, it is our hope that our presentation will encourage a more sober attitude towards this sector and save Zimbabwean researchers and policy makers some of the euphoria that afflicted much of Africa at the "discovery" of the informal sector

Africa's quest for food security : what is the role of urban agriculture?

The history of urban agriculture in Africa dates to the colonial era when farming flourished in urban areas, largely to meet consumption needs of bureaucrats, settlers, and other elites. Today, urban agriculture is becoming increasingly significant as a source of household food, a trend that is closely linked to declining incomes of vulnerable urban households in the wake of neoliberal economic restructuring, high rates of urbanisation, and the need to serve an emerging niche market in African cities. Urban agriculture is generally viewed as a potentially viable policy response to the complex challenge of feeding a burgeoning mass of urban residents amidst decline in food production in rural areas. Also, recent concern regarding climate change and the need to reduce the environmental footprint that comes from transporting food over long distances has given impetus to the need for urban agriculture. The aforementioned notwithstanding, the balance of evidence from existing literature on urban agriculture indicates that the practice faces varying degrees of opposition from urban authorities and policy-makers, who generally underestimate its actual value and contribution to urban poverty and food insecurity. The apparent lack of political will necessary to promote African urban agriculture over the years is reflected in weak or absent policy frameworks over the years, resulting in an enormous capacity deficit. Policy makers and planners need systematic information for planning and managing capacity development centered on urban agriculture. Such a focus on urban agriculture will unlock its potential to address the growing urban demand for food and to alleviate urban poverty.

ABSTRACT

Covid-19 and the Return of the State in Africa

Abstract: As African countries battled the Covid-19 crisis in 2020, one of the questions that were raised was whether the state was taking a central stage in the affairs of society, especially solutions to major problems. The question was triggered by the fact that there has been a decline in the capacity, role and prestige of the state in Africa for decades. Yet it seems that the responses to Covid-19, following the WHO guidelines, have placed the state at the centre, without dislocating other stakeholders like the private sector and the civil society. This paper uses the evidence from a select number of African countries of different sizes in various regions of the continent to provide an empirical perspective on the role of the state in Covid-19 responses in 2020 to answer the question of whether Covid-19 has occasioned a return of the state, thus reversing the neoliberal designs in favour of a lean and mean state in Africa

Physical factors contributing to rural water supply functionality performance in Malawi

This report communicates the findings generated from one of the project surveys – deconstruction and forensic analysis of 50 individual water points in Malawi. The report presents the new data generated to Malawi’s groundwater resource potential; the nature and condition of hand-pump borehole installations; and the significance of both of these factors to service performance. Based on the evidence collected, the main physical factor affecting functionality performance within Malawi is shown to be the poor condition of handpump components. Functionality of handpumps is considerably higher than in the other study countries, Ethiopia and Uganda, and the resource potential, depth to groundwater and recharge are generally favourable. Improved systems for rapid maintenance and repair would help increase functionality further. This finding should not, however, be considered to be the only driving force of functionality outcomes in these regions of Malawi, and the results of this survey need to be examined alongside the wider project findings. Wider institutional arrangements, resources and dynamics, are likely to play a significant role in the implementation of appropriate borehole construction, siting and design; procurement processes; and the management capacity available for water points at national to local levels

Photoluminescent diamond nanoparticles for cell labeling: study of the uptake mechanism in mammalian cells

Diamond nanoparticles (nanodiamonds) have been recently proposed as new labels for cellular imaging. For small nanodiamonds (size <40 nm) resonant laser scattering and Raman scattering cross-sections are too small to allow single nanoparticle observation. Nanodiamonds can however be rendered photoluminescent with a perfect photostability at room temperature. Such a remarkable property allows easier single-particle tracking over long time-scales. In this work we use photoluminescent nanodiamonds of size <50 nm for intracellular labeling and investigate the mechanism of their uptake by living cells . By blocking selectively different uptake processes we show that nanodiamonds enter cells mainly by endocytosis and converging data indicate that it is clathrin mediated. We also examine nanodiamonds intracellular localization in endocytic vesicles using immunofluorescence and transmission electron microscopy. We find a high degree of colocalization between vesicles and the biggest nanoparticles or aggregates, while the smallest particles appear free in the cytosol. Our results pave the way for the use of photoluminescent nanodiamonds in targeted intracellular labeling or biomolecule deliver

Eureka and beyond: mining's impact on African urbanisation

This collection brings separate literatures on mining and urbanisation together at a time when both artisanal and large-scale mining are expanding in many African economies. While much has been written about contestation over land and mineral rights, the impact of mining on settlement, notably its catalytic and fluctuating effects on migration and urban growth, has been largely ignored. African nation-states’ urbanisation trends have shown considerable variation over the past half century. The current surge in ‘new’ mining countries and the slow-down in ‘old’ mining countries are generating some remarkable settlement patterns and welfare outcomes. Presently, the African continent is a laboratory of national mining experiences. This special issue on African mining and urbanisation encompasses a wide cross-section of country case studies: beginning with the historical experiences of mining in Southern Africa (South Africa, Zambia, Zimbabwe), followed by more recent mineralizing trends in comparatively new mineral-producing countries (Tanzania) and an established West African gold producer (Ghana), before turning to the influence of conflict minerals (Angola, the Democratic Republic of Congo and Sierra Leone)

Commodifying development experience: deconstructing development as gift in the development blockbuster

This paper discusses the recent rise of popular ‘blockbuster’ books written by international development industry insiders and produced by commercial publishers. The paper explores a set of common stylistic devices found within this emerging genre. Though each book is different, a key trope is the story of an author's earlier professional life—the hard lessons and gritty insights that have supposedly emerged from it—that normally underpins each narrative. By living the challenges involved in development work at first hand, and by making mistakes and experiencing epiphanies along the way, these author-professionals want readers to know that they have found out the hard way that long-cherished beliefs about development now need to be questioned. Readers are invited to relive these lessons and epiphanies, and to think and act differently about development by upholding a highly pragmatic form of development professionalism. Combining elements of research monograph, self-help book and personal memoir, these development blockbuster books can be understood not only as commodities, but also as part of the development gift. The authors promise a gift of experience but, in reality, these books are mundane commodities enmeshed in capitalist exchange relations

Surgical care for the direct and indirect victims of violence in the eastern Democratic Republic of Congo

ABSTRACT: BACKGROUND: The provision of surgical assistance in conflict is often associated with care for victims of violence. However, there is an increasing appreciation that surgical care is needed for non-traumatic morbidities. In this paper we report on surgical interventions carried out by Medecins sans Frontieres in Masisi, North Kivu, Democratic Republic of Congo to contribute to the scarce evidence base on surgical needs in conflict. METHODS: We analysed data on all surgical interventions done at Masisi district hospital between September 2007 to December 2009. Types of interventions are described, and logistic regression used to model associations with violence-related injury. RESULTS: 2869 operations were performed on 2441 patients. Obstetric emergencies accounted for over half (675, 57%) of all surgical pathology and infections for another quarter (160, 14%). Trauma-related injuries accounted for only one quarter (681, 24%) of all interventions; among these, 363 (13%) were violence-related. Male gender (adjusted odds ratio (AOR)=20.0, p<0.001), military status (AOR=4.1, p<0.001), and age less than 20 years (AOR=2.1, p<0.001) were associated with violence-related injury. Immediate peri-operative mortality was 0.2%. CONCLUSIONS: In this study, most surgical interventions were unrelated to violent trauma and rather reflected the general surgical needs of a low-income tropical country. Programs in conflict zones in low-income countries need to be prepared to treat both the war-wounded and non-trauma related life-threatening surgical needs of the general population. Given the limited surgical workforce in these areas, training of local staff and task shifting is recommended to support broad availability of essential surgical care. Further studies into the surgical needs of the population are warranted, including population-based surveys to improve program planning and resource allocation and the effectiveness of the humanitarian response
