People, process and policy perspectives on food security: An exploration using systems archetypes

Sharif, Amir M., Irani, Zahir 03 June 2016 (has links)
No / This paper aims to identify a wider holistic view of the inter-relationships relating to food security from a people, process and policy perspective. This is so that decision and policy makers can identify relevant alignments between disparate and conflicting priority elements in the field. Noting the complexity of inter-related challenges posed by food security, food supply chains and growing concerns over food waste, this paper also seeks to identify cross-cutting themes relative to shared energy and water security objectives also. The authors develop and adapt an existing food security framework to encapsulate the above culminating in a systems archetype that defines the intimate feed-forward relationship. As a viewpoint piece, there is no empirical work to report in this paper. An exploratory review of the literature has allowed for the extraction of food security concerns that need the attention of stakeholders across the enterprise to ensure robust food supply chains can be created, maintained and sustained through a better understanding and usage of information, knowledge and data. The authors present an adaptation of an existing food security framework to include dimensions of people, process and policy through the inclusion of a number of broad thematic areas including (amongst others): management best practices; sustainable business operations; consumption rights, behaviours and trading policies; lifecycle management; recovery and extraction; regulatory changes and policy reform; environmental and climate change impacts. The authors outline an overarching systems archetype based upon a combination of the Limits of Growth, Tragedy of the Commons and Attractiveness Principle archetypes. In doing so, providing decision and policy makers to identify and explore a range of food security scenarios and potential outcomes. This paper is a position paper that provides strategic directions on the impact of people, process and policy aspects on the development of food security policies from the perspective of local and central government decision makers. This paper provides a holistic worldview on key aspects of the global and national food security debate that seeks to assist decision and policy makers frame their decisions and policy interventions across dimensions of people, process and policy. Noting the impact of securing and maintaining the production, supply, consumption, health benefits and waste recovery aspects of food this paper provides a perspective on the inter-relationships that exist within the topical area and the socially mediated inter-relationships which exist and should be considered when engaging with the food security and food supply chain topical area. The paper raises awareness and highlights inherent inter-relationships within the food debate for the benefit of decision and policy makers present at the organisational level, specifically around people, process and policy.

Enablers to implement sustainable initiatives in agri-food supply chains

Mangla, S.K., Luthra, S., Rich, N., Kumar, D., Rana, Nripendra P., Dwivedi, Y.K. 26 September 2020 (has links)
Yes / Due to rapid agricultural industrialization, increased global food demand, and, increasing concerns related to food quality and safety, the concepts of sustainability and supply chain transparency are becoming critically important to the agriculture and agri-food sector. The new focus on sustainability performance objectives emphasizes the effective utilization and consumption of natural resources to balance ecological, economic and societal aspects of agri-food businesses. The management of sustainability adds a new demand on business managers who often have small profits and receive stringent requirements from large powerful customers and retailers. In this paper, we recognize and analyze the key enablers in implementing sustainable initiatives for Agri-Food Supply Chains (A-FSCs). Ten important sustainability driven enablers were considered from a rigorous literature review and phase of expert consultation. The identified enablers were then analyzed using a combined Interpretive Structural Modeling (ISM) - fuzzy Decision Making Trial and Evaluation Laboratory (DEMATEL) based framework. The ISM approach enabled an appreciation of the contextual relationships among the enablers and to classify the enablers based on their driving and dependence potential. The fuzzy DEMATEL technique supported the determination of the influential and influenced enablers and also to categorize them into cause and effect groups. An empirical case study, drawn from a vegetable and fruit retail supply chain in India, is used to focus and test the applicability of the proposed research framework. The paper facilitates professional management practice and researchers to uncover and explore the enablers for the real execution of sustainability oriented initiatives in the agri-food business sector.

Determining Sustainability Key Performance Indicators for Food Loss Reduction

Al-Dalaeen, Q.R., Sivarajah, Uthayasankar, Irani, Zahir 15 November 2020 (has links)
Yes / Purpose: this paper presents notable themes regarding the relationship between sustainability development and the food loss issue. In doing so, it provides coherent knowledge concerning this global problem and highlights the key research areas in this context. Design/methodology/approach: this paper is a viewpoint piece; normative literature and supposition are used to orientate the views of the authors. Findings: this paper has identified the main causes of food loss at each stage of the food supply chain. It has then classified the causes into three groups based on organisational environment: internal causes, micro-environmental causes and macro-environmental causes. In addition, the authors suggest a need to adopt a holistic view of the performance measurement system in the food industry through incorporating sustainability pillars with traditional performance perspectives in the context of food loss. Practical implications: food loss generating from various causes along the supply chain means that more food should flow across the supply chains to reach consumers’ homes. This paper provides reassuring insights that will help the decision-makers in food companies to revise the performance measurement system in the context of food loss reduction. Social implications: reducing food loss will contribute to increasing food availability and decreasing food prices, which leads to strengthening economic and physical access for those people who are not able to get food. Consequently, it considers a mandatory step to enhance food security. Originality/value: to raise the significance of food loss reduction along the supply chain and to stress an urgent need to adopt a holistic view of the sustainability performance measurement system with a particular focus on the food loss issue.

Supply chain agility responding to unprecedented changes: empirical evidence from the UK food supply chain during COVID-19 crisis

Do, Q., Mishra, N., Wulandhari, N.B.I., Ramudhin, A., Sivarajah, Uthayasankar, Milligan, G. 02 May 2021 (has links)
Yes / Purpose: The COVID-19 outbreak has imposed extensive shocks embracing all stages of the food supply chain (FSC). Although the magnitude is still unfolding, the FSC responds with remarkable speed, to mitigate the disruptive consequences and sustain operations. This motivates us to investigate how operationalising supply chain agility (SCA) practices has occurred amid the COVID-19 crisis and expectations for how those practices could transform the supply chain in the post-COVID-19 era. Design: Following an exploratory case-based design, we examine the various agile responses that three supply chains (meat, fresh vegetables and bread) adopted and elaborate using the dynamic capability (DC) theoretical lens. Findings: First, the findings demonstrate how, in the wake of the COVID-19 pandemic, each affected case pursued various agile responses through sensing and seizing capabilities. Sensing includes identifying and assessing the relevant opportunities and threats associated with the specific supply chain context. Seizing involves acquiring, combining and modifying the tangible and intangible resources at the firm and supply chain levels. Second, supply chain transformation is likely if firms and their supply chain develop the sustaining capability to ensure that the desirable changes outlast the crisis. Originality: This study provides a novel and unique perspective on the role of SCA in crisis—in this case, the pandemic. We synthesise the empirical stories of the agile responses in the FSC and elaborate on the DC framework, to identify theoretical and practical implications. We establish the sustaining capability as the missing DC capability for enabling transformation in the post-COVID-19 era. Practical contribution: This study provides an actionable guide for practitioners to develop agile responses to systemic changes in times of crisis and to sustain favourable changes so as to enable their outlasting the crisis. / Project 777742: EC H2020-MSCA-RISE-2017

Food security across the enterprise: a puzzle, problem or mess for a circular economy?

Irani, Zahir, Sharif, Amir M. 07 October 2017 (has links)
Yes / Purpose – The purpose of this paper is to explore the use, applicability and relevance of strategic planning as a process and tool when applied to exploring food security challenges, in the context of existing research on food security and food waste in the food supply chain. The issues associated with robust and resilient food supply chains within a circular economy are increasingly being seen as supportive of creating enhanced levels of food security but the authors argue that this is only sustainable when strategically planned as part of a cross-enterprise, information-rich and complex supply chain. The relevance of the Political, Economic, Social, Technological, Legal and Environmental (PESTLE) strategic planning tool is explored to establish whether it can play a role tacking the complexity of food insecurity (i.e. a lack of food security). Design/methodology/approach – This is a viewpoint piece therefore as a result, thought, normative literature and supposition are used as a means to ground and orientate the views of the authors. Findings – The authors identify and conclude that strategic planning tools like PESTLE across enterprises may not be relevant in supporting the reduction of food insecurity. This conclusion is predicated on the heightened level of complexity surrounding the pursuit of food security and the simplistic categorisation of PESTLE factors in a linear fashion that underpin this tool. Rather, the authors’ call for the use of strategic planning tools that are able to capture a large number of inter-related factors holistically. Practical implications – This insight to the inter-related factors that contribute to food insecurity will allow policy developers, decision makers and others to develop their understanding of how strategic planning can support increased levels of food security within a circular economy and across cross-enterprises. Originality/value – The authors contribute to the literature through a new insight of how normative strategic planning tools need to evolve in a complex, inter-connected world of international business and geo-politics. In doing so, it is expected that this research will motivate others to develop their line of enquiry around uncovering and exploring those inter-relationships connecting PESTLE factors.

Exploring Artificial Intelligence in Food Supply Chains : A Qualitative Study on the Effects of AI from the Retailers’ Perspective

Hermansson, Sofia, Lindgren, Simon January 2024 (has links)
Recent developments in artificial intelligence (AI) have sparked a large interest across various sectors, where it has been praised for its capabilities of transforming the way businesses operate. The food supply chain (FSC) is a particularly complex and unique supply chain due to its nature of dealing with perishable products. With sustainability becoming an increasingly important aspect for stakeholders, it stresses the importance of the FSC optimizing their operations to ensure minimal environmental impact while maximizing efficiency. Although the topic of AI is widely discussed in society, research concerning the topic remains limited. While the existing literature frequently discusses AI’s potential in broad terms, it is lacking in showcasing the practical effects it can entail within specific industries. Therefore, investigating the implications of the technology in the FSC is highly relevant from both a practical and theoretical standpoint. The study’s purpose is to contribute with insights into how the implementation of AI has affected food supply chains in Sweden. It holds an exploratory research design and an inductive research approach, taking the perspective of the inbound logistics part of the FSC. To gain a clear understanding of what practical effects AI has entailed, the study highlights both the dynamics of the FSC before implementing AI, as well as its dynamics after implementing it. This study used a qualitative method with semi-structured interviews to obtain its empirical data. The interviews were conducted with two of the large food retailers in Sweden, and a thematic analysis was then employed to identify a few key areas that the empirical findings showed.  The results show that the main areas where AI has affected the FSC is in (1) time-savings, (2) inventory management, (3) waste management, and (4) internal supply chain efficiency. The common denominator between these areas was identified to be the improved forecasting ability that AI provides. Forecasts play a significant role in improving efficiency since they entail a supply chain-wide impact where both suppliers, warehouses, and ultimately the end-customer are impacted from them. However, the findings indicate that although AI is an effective tool, it remains to have certain limitations and still requires human maintenance to properly function.

Provisioning Johannesburg, 1886-1906

Cripps, Elizabeth Ann 02 1900 (has links)
The rapidity of Johannesburg’s growth after the discovery of payable gold in 1886 created a provisioning challenge. Lacking water transport it was dependent on animal-drawn transport until the railways arrived from coastal ports. The local near-subsistence agricultural economy was supplemented by imported foodstuffs, readily available following the industrialisation of food production, processing and distribution in the Atlantic world and the transformation of transport and communication systems by steam, steel and electricity. Improvements in food preservation techniques: canning, refrigeration and freezing also contributed. From 1895 natural disasters ˗ droughts, locust attacks, rinderpest, East Coast fever ˗ and the man-made disaster of the South African War, reduced local supplies and by the time the ZAR became a British colony in 1902 almost all food had to be imported. By 1906, though still an import economy, meat and grain supplies had recovered, and commercial agriculture was responding to the market. / History / M.A (History)

HIV/AIDS and climate in food security crises :a study of Southern Africa, 2001-2005.

Van Riet, Gideon 12 1900 (has links)
Thesis (MA (Political Science.International Studies))--University of Stellenbosch, 2006. / This study is based on the premise that HIV/AIDS and variable rainfall, in other words, events such as droughts and floods (climate), are likely to be prevalent in Southern Africa for the foreseeable future. Thus, these two factors are likely to accompany future food crises in the region. This study investigates the Southern African Food Crisis in the period 2001-2005, with certain objectives in mind. Firstly, the impact of HIV/AIDS and climate on food security is investigated. Secondly, in light of the findings relating to the first objective, it is investigated what an optimal humanitarian intervention in a food crisis in the Southern African context, characterised by variable rainfall and high prevalence of HIV/AIDS, might entail. Finally, the appropriateness of humanitarian interventions in the Southern African Food Crisis to ameliorate the long-term impacts of HIV/AIDS and climate on the region is considered. The study makes use of an extensive literature review, supplemented by a smaller set of e-mail and semi-structured interviews. Especially with regards to the second and third research objectives, the Consortium for the Southern African Food Security Emergency (C-SAFE) is used as a case study of an intervention in the above stated context. C-SAFE – composed of a consortium of international and local non-governmental organisations - is the largest humanitarian intervention programme that was created with the specific goal of ameliorating the food crisis in the Southern African region. They were primarily active in four countries: Lesotho, Malawi, Zambia and Zimbabwe. The study focuses on C-SAFE operations in these four countries in order to asses the impact of variable rainfall and HIV/Aids and other underlying causes – such as macroeconomic factors and government policy – on food insecurity in Southern Africa and to examine how these factors influence a humanitarian intervention programme such as C-SAFE. The most important findings of this study are that neither HIV/AIDS nor climate is driving food insecurity in Southern Africa. The impact of HIV/AIDS can however be devastating at household level. It is found that both factors, serve as catalysts bringing to the fore the underlying vulnerability of households. The findings of this study further suggest that interventions should provide resilience building to shocks such as drought, indicating a complex set of relief and developmental needs in the region. Furthermore, HIV/AIDS can be seen as a crisis in itself, requiring a comprehensive multisectoral response, however possibly requiring special attention in times of food insecurity. Finally it is argued that livelihoods erosion over time has meant that the work of relief agencies fulfilling their mandate, providing short-term relief to households and communities in need, regardless of the quality of such interventions, are ineffectual in addressing cycles of vulnerability in Southern Africa as inadequacies at national level, most notably a lack of government capacity, remain.

The drums of war are the drums of hunger: A comparative analysis of the use of food as a weapon in Darfur and Somalia

Kamphuis, Anneke Imke 03 1900 (has links)
Thesis (MA (Political Science))--University of Stellenbosch, 2010. / ENGLISH ABSTRACT: The aim of this thesis has been to analyse which similarities exist in combatants’ control over food supply lines to non-combatants in African civil conflict and evaluate whether these similarities are sufficient to permit generalisations about the use of food as a weapon in African civil conflict. The nature of this study is both descriptive and explanatory. The case studies of Darfur and Somalia form the descriptive part of this study. This thesis is also explanatory in that it aims to make a first attempt at theory building where such theory did not exist before. I try to explain if, how and why combatants intentionally use food as a means of power in civil conflict. Is the control over food a deliberate and rational choice by combatants or are situations of food scarcity and even hunger or famines simply a consequence of war? The case studies of Darfur and Somalia provide many similarities concerning the impact of conflict on livelihoods and food security. Famine is more an issue of limited access rather than availability. The use of food as a weapon displays a number of important similarities. Attacks on food security can be divided into acts of omission, commission and provision. In Darfur, combatants exercise a greater level of control over food supply lines than in Somalia. Finally, I argue that famine in African civil conflict is highly functional and has a distinct political-economic character. The creation of famine is often deliberate, with a hidden political agenda. In both Darfur and Somalia, attacks on food security serve a political, economic and military rationale. The political logic of attacks on food security was most important in Darfur, although here the signs of a sustainable war economy become apparent. In contrast, in Somalia, food production and procurement are attacked without the intent to destroy the livelihoods of specific societal groups, with the exception of the politically and economically marginalised groups in the south-central part of the country. The political logic is very superficial in Somalia. The level of deliberateness and organisation of attacks on food security, and hence the importance of the political logic, seem to tie in with the level of organisation of the central government, as well as with the presence or absence of a powerful ideology that clearly divides certain sections of the population from others. I recommend that further research be undertaken to analyse if theory on resources and conflict applies to attacks on food. Furthermore, additional research is needed on how to mitigate the negative effects of Food Aid. Finally, it is valuable to investigate to what extent effective government control and/or the presence of a binding ideology affect the importance of the political logic behind the attacks on food security. To this point, this research should be extended to include more case studies, with a specific focus on the factors of governmental control, ideology and political logic. / AFRIKAANSE OPSOMMING: Die doel van hierdie tesis was om die ooreenkomste oor die beheer wat gewapendes oor die voedselvoorsieningslyne vir ongewapendes in Afrika se siviele konflikte te ondersoek, en om te evalueer of hierdie ooreenkomste genoegsaam is om veralgemenings te maak oor die gebruik van voedsel as ‘n wapen in hierdie konflik. Die omvang van hierdie studie is beide beskrywend en verduidelikend. Die gevallestudies van Darfur en Somalia vorm die beskrywende deel van hierdie studie. Hierdie thesis is ook verduidelikend in die sin dat dit poog om ‘n eerste probeerslag te skep vir die bou van teorie waar dit voorheen nog nie bestaan het nie. Hierdie studie poog om te verduidelik as, hoe en wanneer gewapendes voedselvoorrade intentioneel gebruik as ‘n bron van mag in siviele konflikte. Is die beheer oor voedsel deurdagte en rationele keuse deur gewapendes, of is situasies van voedseltekorte of selfs hongersnood eenvoudig ‘n gevolg van oorlogvoering? Die gevallestudies van Darfur en Somalia bied vele ooreenkomste rakende die impak van konflik op oorlewingsmeganismes en voedselsekuriteit. Hongersnood is meer ‘n geval van beperkte toegang, eerder as beskikbaarheid. Gebruik van voedsel as wapen het ‘n aantal belangrike ooreenkomste opgelewer. Aanvalle op voedselsekuriteit kan opgedeel word in dade van weerhoud, kommissie en provisie. In Darfur het gewapendes ‘n groter vlak van beheer oor die lyne van voedselverskaffing as in Somalia. Uiteindelik is dit die argument van hierdie tesis dat hongersnood in siviele konflik in Afrika grootliks funksioneel is en duidelike polities/ekonomies van aard is. Hierdie oorsaak van hongersnood is telkemale opsetlik met ‘n gepaardgaande verskuilde politiese agenda. In beide Darfur en Somalia het aanvalle op voedselsekuriteit ‘n politiese, ekonomiese en militêre rationale. Die politieke aard van aanvalle op voedselsekuriteit was besonder opmerksaam in Darfur, alhoewel tekens van ‘n onderhoudbare oorlogsekonomie duidelik begin word het. In teenstelling is voedselproduksie en versekering in Somalia onder aanval sonder die bedoeling om die lewenswyse van sekere sosiale groepe te vernietig of van stryk te bring, met die uitsondering van die politiese en ekonomies gemarginaliseerde groepe in die suid-centrale deel van die land. Die politieke logika is baie oppervlakkig in die geval van Somalia. Die vlak van beplanning rakende aanvalle op voedselsekuriteit, en gepaardgaande die belang van die politieke redenasies, blyk samehorig te wees met die vlak van organisasie van die sentrale regering, asook die teenwoordigheid of afwesigheid van ‘n sterk ideologie wat sekere dele van die populasie duidelik onderskei van andere. Ek beveel aan dat verdere navorsing onderneem word om te analiseer of gepaste teorie op hulpmiddele en konflik relevant geag kan word in verband met voedselaanvalle. Verder word addisionele navorsing benodig ingevolge die beperking en kontrolering van die newe effekte van Food Aid. Uiteindelik is dit van pas en belangrik om die omvang van effektiewe regeringsbeheer en/of die teenwoordigheid van ‘n oorkoepelende en bindende ideologie aangaande die effek daarvan op die politieke beredenerings agter die aanvalle op voedselsekuriteit te bestudeer. In hierdie opsig behoort hierdie navorsing uitgebrei te word om meer gevallestudies in te sluit met ‘n spesifieke fokus op die individuele faktore van regeringsbeheer, ideologie en politieke redenasie.

Evaluation of the determinants of improved food security in South Africa by 2030

Vermeulen, Cornel 03 1900 (has links)
Thesis (MPhil)--Stellenbosch University, 2011. / Africa is the continent where home sapiens was born and with its worn out soils, fitful rain and rising population could very well provide a glimpse of our species’ future. The trends that are behind the current deterioration in food security go far beyond agriculture itself. South Africa is food secure at a national level and has been meeting its food needs from domestic sources in the past twenty years. However, in spite of its food secure status, 35% or 14.3 million South Africans are vulnerable to food insecurity. Food security challenges appear to be considerable against a backdrop of a South Africa being a net importer of wheat together with local cereal production that can fluctuate by up to 36% between years. It is unknown to what extend the true impact of climate change might affect this and other agricultural activity; a declining indigenous population as the HIV/AIDS pandemic takes effect; a population poorly endowed with an entitlement to gain access to sufficient food and nutrition; a dependency on oil for energy resulting in an outflow of foreign exchange, expensive agriculture and agricultural crops changed into fuel crops and markets that allocates the limited resources, but not feeding the needy poor. Considering the above, the determinants of food security for South Africa were grouped under the following headings: - Entitlement - Demography - Agriculture - Energy - Climate change - Markets. Nobody who has money to pay for food is starving therefore, given the pervasiveness of malnutrition, the money made by merchants in the food trade does seem an affront to common notions of economic justice. The economic and political point is missed when merchants are blamed for conditions that promoted huge food imports and malnutrition. Merchants are not interested in famine but in commercial markets. These merchants thrive upon a system that excludes the hungry. Recent protectionist behaviour by food export countries and the structural shift in the demand of food require South Africa to evaluate its food security determinants. South Africa requires accurate policies to guide its food security efforts towards 2030.
