Salinity intrusion and food security : evidence from three food systems in south-western Bangladesh

Munim, Khandaker Mohammed Ashraful 2013 (has links)
Bangladesh is susceptible to salinity intrusion into water and soil during the dry season in the country's south-western region. Climate change is expected to exacerbate this situation, allowing salinity to penetrate into further inland. Some scholars have suggested that salinity has deleterious impact on rice production but favours shrimp production. Yet it is unclear what effect this would have on peoples' food security. This research, therefore, assessed food security, encompassing dietary quantity and quality, seasonality and food vulnerability of households, basing their livelihoods on three prevalent food/farming systems - traditional rice, export-oriented shrimp and innovative mixed (rice and shrimp) systems. Five study areas in southwestern Bangladesh were explored, depicting differential salinity exposures: two each from shrimp and rice and one from mixed systems. Five representative villages were chosen and households were selected using simple random sampling. A questionnaire survey of 385 households provided socio-economic and demographic data, and five focus groups revealed seasonal patterns in food security. Results suggest that despite its clear importance, salinity intrusion is not responsible for significantly restricting or enhancing their food security; rather farming system plays the major role. While the extent of food insecurity is lowest in the mixed system, with shorter hungry season, it is considerably high in the shrimp system. Agricultural labourers are the most food insecure and vulnerable class in all systems, their condition being worst in the shrimp system. Results show that high proportion of marginal, small and medium landholders/farmers remain food insecure and vulnerable in the higher-income generating shrimp system. The corresponding proportions are lower in rice system and lowest in mixed system. Intriguingly, food security in the mixed system is not undermined under moderate salinity exposure; rather it offers the best food security and least food vulnerability among the three systems. The results have important policy implications for food security under climate change.

Consumer concerns about animal welfare and its impact on food choice in Ireland

Dunne, Hilary 2008 (has links)
Evidence of growing consumer concerns about animal welfare demonstrates that it is an important issue for consumers across Europe. Gaps have been identified between high consumer concerns about animal welfare and relatively low market share for animal friendly products. This research examines the nature and extent of consumer concerns about animal welfare using mixed methods, namely; focus groups (n=4), laddering interviews (n=60) and a representative survey (n=500).

The impact of shocks and bargaining power on intra-household food and nutrition security in rural Bangladesh : the importance of gender targeting

Gaskin-Peters, Natasha Theresa 2014 (has links)
This thesis examines the role of gender in the achievement of the food and nutrition security in rural Bangladesh. It does this through the use of anthropometric measures as well intra-household allocation of calories and micronutrients. Quantile regression estimation is used to examine the impact of negative shocks on the calorie and micronutrient intake of individuals and the extent to which gender targeted technology helps these individuals to mitigate the impact of these shocks. Overall, both illness and floods are the two dominant shocks but the magnitude of floods is higher. In fact, I find evidence of women's calorie intake being affected by three negative shocks namely: asset (loss of livestock, crop, productive and consumption assets), illness (loss of income due to the household head being ill and medical expenses due to illness of any person) and flood while that of men is affected only by the latter two. On the other hand, the calorie intake of children in certain quantiles are affected negatively by asset, illness, flood, death (death of the main earner and other earners) and wedding (dowry and other wedding payments). In relation to micro nutrients, I also find strong evidence of both floods and illness along with assets reducing the micronutrient intake of individuals. However, despite the reduction in calorie and micronutrient intake of individuals when negative shocks occur, technology that targets women helps all individuals to mitigate the impact of these shocks except in the event of flooding. In addition, Two-Stage least Squares, Limited Maximum Likelihood and Continuously Updating Estimator models are used to examine the impact of a woman's status on the nutritional status of her child/children because of the presence of weak instruments. I find that a woman's bargaining power - measured using the control of current assets - has a positive a positive and significant impact on the 8MI of her child/children. These findings have significant implications for the achievement of food and nutrition security in poor countries, especially in Asia.

Food aid, power and profit : an historical analysis of the relation between food aid and governance in Sudan

Jaspars, Susanne Sophia Elisabeth 2015 (has links)
Sudan represents one of the world's most severe protracted crises and the country is one of the world's longest-running and largest recipients of food aid. The recent Darfur conflict led to the World Food Programme's largest operation globally. Yet by 2014 international agencies had only limited access to war-affected populations and had decreased food aid despite ongoing conflict, and the Sudan government had come to control who received food aid. Malnutrition levels remained high. This thesis argues that the 'actually existing development' resulting from long-term food aid has benefited the Sudan government and private sector but abandons populations to become resilient to permanent emergency. Using concepts of governmentality and genealogy, the thesis explores how food aid regimes of practices have co-evolved with local governance. It analyses the links between practices, their underlying concepts and assumptions, the truths they produce, and the actual as well as intended effects. The focus is on their effects on human behaviour, power relations and political economy, and the implications for local livelihoods. Methods included examining policy documents, project reports, and interviews with government officials, aid workers, traders, transporters and beneficiaries in Khartoum and North Darfur. Shifts between regimes of practices were brought about by changes in global politics, food crises, the failures of food aid practices and reactions by the Sudan government, which led to a gradual depoliticisation and neoliberalisation of food security and nutrition. In fifty years, food aid has rarely had the effect of saving lives and supporting livelihoods, but the consequences for Sudan's political economy and its aid system have been enormous. The thesis analyses these political and economic consequences and how long-term food aid has led to the Sudan government's own food aid apparatus. The research contributes to knowledge about the political economy of aid and highlights the need for radical reform of the aid industry.

Food in utopia : eating our way to perfection

Levi, Jane Elizabeth 2015 (has links)
This work asks what part food has played in the formation, daily life and success (or failure) of utopian communities, andconsiders why food is significant to utopian ideas. In this connection it primarily considers three things: the ways in which food and gastronomy have figured in utopian thinking to express or attempt to realise better ways of living; the extent to which utopian ideas about food have become mainstream, and in what ways; and why some aspects of utopian thinking on the subject have been adopted and others not. The approach is interdisciplinary, and although the thesis is built on detailed textual analysis of primary sources, it also draws on the methodologies of literature, history, sociology and cultural anthropology to provide a more complete picture of the food-­‐related theories and experiences of selected utopias in Europe and North America between the mid-­‐seventeenth and twenty-­‐first centuries. Moreover, the discussion engages with the theoretical proposals of utopian thinkers as they relate to eating, dietary choices, agriculture, production and food supply, assessing the every-­‐ day experience of people executing these ideas inside utopian communities. The thesis places examples into their historical context with an eye to contemporaneous mainstream ideas concerning food and gastronomy, paying particular attention to their mutual influences, conflicts and points of differentiation. Often dismissed as fictional fantasies, utopian ideas are frequently condemned as unrealistic, impossible or the work of fanatics. While notions of utopia may lie on the borderline between the possible and the impossible, the factual and the fictional, a review of a critical everyday component—food—makes it possible to take a fresh look at this conceptual “no place”. By providing alternative perspectives on the origins of many of our current preoccupations with food-­‐related questions, new ways of thinking about both utopia and our attitudes to food emerge.

Energy scarcity and food security : strategies for transition to resilient food system governance

Foord, Wayne 2016 (has links)
This thesis addresses the impacts of emerging energy scarcity on food security, and explores strategies for transition to a sustainable food system. The core research questions focus on the transition movement, its political strategy, and proposals for food sustainability. Contextual questions include: What post-peak oil scenarios are plausible/implausible given current evidence regarding global oil production, and available energy alternatives? Do any current trends indicate the unfolding of one scenario, in particular? And how might this scenario impact on food security, and what are the implications for transition movement strategy? Evidence is presented that global oil production has already ‘plateaued’, and the most likely scenarios for industrial societies now lie on a continuum between forced, gradual energy descent and rapid collapse. Emerging trends indicate that energy scarcity is associated with the evolution of a post-liberal order, as anticipated by some contributors to the ‘politics of scarcity’ debate in the 1970’s. These trends are also manifesting within the global food system, in the form of ‘land-grabbing’ and widespread imposition of GM-based industrial agriculture. In light of imminent forced energy descent, emerging global trends, and learning from the Cuban Special Period, it is argued that both green political theory and transition movement strategy should focus on the contested politics of transition, in conjunction with a prospective politics that steers transition towards a new societal equilibrium. A diverse, adaptive repertoire of political strategies is proposed, including: solutions-based activism; oppositional activism; insurgent citizenship; transformative engagement with local government; and ‘de-linking’ initiatives. Scaling up of local Transition initiatives should include: promotion of regional solidarity networks between urban centres; regional food system planning; and alliance-building with other counter-hegemonic social movements. It is further proposed that a ‘food sovereignty’ framing is adopted, and that scaled up, farm sector agroecology is promoted, to complement existing permaculture and organic approaches.

Modelling greenhouse gas emissions for the UK and overseas food production

York, Elizabeth 2012 (has links)
Despite the large quantity of research undertaken into the sustainability of food production and transportation systems, there is currently little consensus on the total contribution that greenhouse gas (GHG) emissions make to the overall GHG budget of food production systems. To date, most research has focused on the miles that food has travelled and the energy put into the production of pesticides and fertilisers associated with crop production. Understanding whether food imported from distant countries has a higher GHG footprint than locally produced food remains a very topical issue. Our fundamental lack of knowledge of this issue is limiting policy development in this area. Due to difficulties in field measurements mathematical models such as DNDC (DeNitrification DeComposititon) are being used to predict GHG emissions from different ecosystems. In this thesis, a combination of field measurements and model simulations were used to evaluate GHG emissions from different agricultural production systems undertaken in different countries (UK, Spain and Kenya). This thesis also considered the accuracy of the model by undertaking a sensitivity analysis and evaluating the outputs from different model versions. In addition, the accuracy of using a QIO value approach to predict organic matter degradation was also evaluated. Overall, the results suggested that different model versions gave varying outputs, suggesting that predictions of GHG emissions obtained with models such as DNDC should be treated with caution. However, the model did predict similar results to those obtained in the field, although the model outputs tended to be higher. For comparison of GHG emissions from vegetable types grown in different geographical regions, no specific region produced lower GHG results when averaged across all crops. However, when individual crops were considered, Spain had the highest GHG emissions. The models showed different degrees of sensitivity to different inputs, with some not showing any variation at all. In the Q10 evaluation experiments the Q10 values varied greatly, though all gave results above the standard Q10 of 2. Further research is needed into the accuracy of climate and farm management models, and whether or not it is necessary to compare large data sets when considering different vegetable types and areas.
