The allocation of labour to perennial crops

The production of perennial crops by smallholders has played an important part in many developing economies, something that is no less true in the stabilization and structural adjustment era today than it was in colonial or post-colonial times. Yet, as this review shows, knowledge about smallholder perennial crop production systems is sporadic and incomplete. This is especially so concerning the non-price related opportunities and constraints which determine under what conditions smallholders are inclined to produce perennial crops. This is a review of material published since the 1940s which shows the factors involved in labour decisionmaking: the interaction of family and hired labour, longand short-term contracts; the effect of different kinship systems; and of gender and age. It also looks at the threats posed by HN/AIDS and natural disasters. The review shows how labour can determine what crops are grown as well as the way crops and seasonality impose their own restrictions on the choice of labour. The conclusions show the importance of taking account of the decision-making process concerning labour during policy planning as well as the limitations labour imposes on perennial crop production. They also identify gaps in current knowledge and suggest areas for further research

Pastoral groups and cereal storage systems. Report on an exploratory visit to Nigeria (NRI report no. R1999 (S))

Following an extensive literature review (Fowler and Moorehead, 1992) into grain storage and marketing by pastoralists, a first field study was conducted to look at the social and technical aspects of grain storage, marketing and production amongst Fulani pastoralists in Nigeria

Moving from traditional government to new adaptive governance: the changing face of food security responses in South Africa

The food system faces increasing pressure from dynamic and interactive, environmental, political and socio-economic stressors. Tackling the complexity that arises from such interactions requires a new form of 'adaptive governance'. This paper provides a review of various conceptions of governance from a monocentric or politicotechnical understanding of governance through to adaptive governance that is based in complex adaptive systems theory. The review is grounded by a critique of the existing institutional structures responsible for food security in South Africa. The current Integrated Food Security Strategy and tasked governmental departments are not sufficiently flexible or coordinated to deal with an issue as multi-scalar and multidisciplinary as food security. However, actions taken in the non-governmental sector signal the emergence of a new type of governance. Apart from an increasing recognition of food security as an issue of concern in the country, there is also evidence of a changing governance structure including collaboration between diverse stakeholders. We review these governance trends with an understanding of the food system as a complex adaptive socio-ecological system where actors in the food system self-organize into more flexible networks that can better adapt to uncertain pressure

Implementation and evaluation of a transit dosimetry system for treatment verification

PURPOSE: To evaluate a formalism for transit dosimetry using a phantom study and prospectively evaluate the protocol on a patient population undergoing 3D conformal radiotherapy. METHODS: Amorphous silicon EPIDs were calibrated for dose and used to acquire images of delivered fields. The measured EPID dose map was back-projected using the planning CT images to calculate dose at pre-specified points within the patient using commercially available software, EPIgray (DOSIsoft, France). This software compared computed back-projected dose with treatment planning system dose. A series of tests were performed on solid water phantoms (linearity, field size effects, off-axis effects). 37 patients were enrolled in the prospective study. RESULTS: The EPID dose response was stable and linear with dose. For all tested field sizes the agreement was good between EPID-derived and treatment planning system dose in the central axis, with performance stability up to a measured depth of 18cm (agreement within -0.5% at 10cm depth on the central axis and within -1.4% at 2cm off-axis). 126 transit images were analysed of 37 3D-conformal patients. Patient results demonstrated the potential of EPIgray with 91% of all delivered fields achieved the initial set tolerance level of ΔD of 0±5-cGy or %ΔD of 0±5%. CONCLUSIONS: The in vivo dose verification method was simple to implement, with very few commissioning measurements needed. The system required no extra dose to the patient, and importantly was able to detect patient position errors that impacted on dose delivery in two of cases

Political Corporate Social Responsibility: Reviewing Theories and Setting New Agendas

There has been rising interest in political corporate social responsibility (political CSR), defined as activities where CSR has an intended or unintended political impact, or where intended or unintended political impacts on CSR exist. Based on a survey and content analysis of 146 peer-reviewed academic articles from 18 journals over the 14-year period 2000–2013, this paper systematically reviews the existing applications of general theories (such as legitimacy theory, the resource-based view and Habermasian political theory) within the political CSR literature.The survey indicates that the political CSR field is dominated by institutional theory and stakeholder theory, but future theory development needs to go beyond these theories in order to address a number of critical gaps. This review specifically points to several avenues for future political CSR research with regard to the individual level of analysis, domain integration and political CSR in multinational enterprises. The paper ends with a call for a new theory-informed and pluralist research agenda on political CSR to integrate different perspectives and re-examine the role of the state

The Paradox of Power in CSR: A Case Study on Implementation

Purpose Although current literature assumes positive outcomes for stakeholders resulting from an increase in power associated with CSR, this research suggests that this increase can lead to conflict within organizations, resulting in almost complete inactivity on CSR. Methods A single in-depth case study, focusing on power as an embedded concept. Results Empirical evidence is used to demonstrate how some actors use CSR to improve their own positions within an organization. Resource dependence theory is used to highlight why this may be a more significant concern for CSR. Conclusions Increasing power for CSR has the potential to offer actors associated with it increased personal power, and thus can attract opportunistic actors with little interest in realizing the benefits of CSR for the company and its stakeholders. Thus power can be an impediment to furthering CSR strategy and activities at the individual and organizational level

Global nuts and local mangoes: a critical reading of the UNDP Growing Sustainable Business Initiative in Kenya

This article provides a conceptual and empirical assessment of UN brokered partnerships that seek to deepen or create inclusive and sustainable agricultural supply chains in sub-Saharan Africa. More specifically it appraises the decision-making mechanisms, processes of partnership brokerage and project implementation within the UNDP Growing Sustainable Business Initiative (GSB) in Kenya. The paper argues that the lack of bottom-up participation in decision-making mechanisms and the predominantly economic imperatives driving the GSB partnership projects have failed to reach out to the partnerships’ intended beneficiaries—Kenyan small producers of nuts and mangoes. In conclusion it is suggested that opening up the GSB platform might hold the promise of reconciling sustainable business models with (some) poverty reduction

Unintentional social consequences of disorganised marketing of corporate social responsibility: figurational insights into the oil and gas sector in Africa.

Corporate Social Responsibility (CSR) has become a concept that is widely associated with large transnational corporations (TNCs) and increasingly small and medium sized enterprises (SMEs). The concept is contentious with wide ranging debates about intent and impact, not least from critics who perceive CSR to ostensibly be a marketing tool. Before examining some of the current flaws within CSR, it is important to establish how the concept is being applied
