Sugar-Sweetened Beverage Taxes in Brazil

Objectives. We investigated whether taxing sugar-sweetened beverages (SSBs) would improve the diets of households in Brazil. Methods. We used household food consumption data that the Brazilian Institute of Geography and Statistics collected in 2002-2003 from a nationally representative sample of 48470 Brazilian households. The consumption of SSBs is expressed as the total SSB calories consumed and as the SSB percentage of the total calories purchased. We investigated price elasticity with regression models, controlling for demographic variables, income, and prices of all other foods and drinks. Results. Increases in the price of SSBs led to reductions in consumption. A 1.00% increase in the price of SSBs led to a 0.85% reduction of SSB calories consumed (1.03% reduction for the poor and 0.63% for the nonpoor). Increased income had a positive effect on SSB consumption, but the effect was less than half the size of the price elasticity (0.41% increase in SSB calories consumed for every 1.00% increase in income). Conclusions. High SSB price elasticity in Brazil indicates that a tax on purchased weight or volume would lead to reductions in SSB consumption.

Essays in Health Economics

In the first chapter we develop a theoretical model investigating food consumption and body weight with a novel assumption regarding human caloric expenditure (i.e. metabolism), in order to investigate why individuals can be rationally trapped in an excessive weight equilibrium and why they struggle to lose weight even when offered incentives for weight-loss. This assumption allows the theoretical model to have multiple equilibria and to provide an explanation for why losing weight is so difficult even in the presence of incentives, without relying on rational addiction, time-inconsistency preferences or bounded rationality. In addition to this result we are able to characterize under which circumstances a temporary incentive can create a persistent weight loss. In the second chapter we investigate the possible contributions that social norms and peer effects had on the spread of obesity. In recent literature peer effects and social norms have been characterized as important pathways for the biological and behavioral spread of body weight, along with decreased food prices and physical activity. We add to this literature by proposing a novel concept of social norm related to what we define as social distortion in weight perception. The theoretical model shows that, in equilibrium, the effect of an increase in peers' weight on i's weight is unrelated to health concerns while it is mainly associated with social concerns. Using regional data from England we prove that such social component is significant in influencing individual weight. In the last chapter we investigate the relationship between body weight and employment probability. Using a semi-parametric regression we show that men and women employment probability do not follow a linear relationship with body mass index (BMI) but rather an inverted U-shaped one, peaking at a BMI way over the clinical threshold for overweight.

Rechtliche Grundlagen für die Ernährungssicherheit in der Schweiz

The Right to Food, as enshrined in international law, has found its way into national constitutions and practices. What matters from a national and international legal point of view is how this policy objective is implemented. In Switzerland, a number of policies and their instruments are relevant here, namely agricultural, supply/stockpile, trade and development policies. This paper (in German) asks whether the policy instruments are coherent and how implementation conflicts and negative spill-over effects could be minimised. It finds that the four policy objectives enshrined in the Federal Constitution are not in themselves incoherent. However, certain Swiss agricultural policy instruments, even where they are compatible with relevant rules of the World Trade Organization (WTO), do have an avoidable negative impact on the Right to Food of developing country producers, because Swiss Food Security is overwhelmingly and increasingly defined by agricultural (self-reliance) policies (“Food Sovereignty”). This implies higher domestic food prices, commercial displacement and food dumping. The conclusions suggest a number of optimisations as a contribution to the presently on-going reform process for 1983 National Economic Supply Act 1983 (NESA), such as virtual stockpiles and taxpayer-financed stockpile costs.

The Early Spörer Minimum – A Period of Extraordinary Climate and Socio-economic Changes in Western and Central Europe

Throughout the last millennium, mankind was affected by prolonged deviations from the climate mean state. While periods like the Maunder Minimum in the 17th century have been assessed in greater detail, earlier cold periods such as the 15th century received much less attention due to the sparse information available. Based on new evidence from different sources ranging from proxy archives to model simulations, it is now possible to provide an end-to-end assessment about the climate state during an exceptionally cold period in the 15th century, the role of internal, unforced climate variability and external forcing in shaping these extreme climatic conditions, and the impacts on and responses of the medieval society in Central Europe. Climate reconstructions from a multitude of natural and human archives indicate that, during winter, the period of the early Spörer Minimum (1431–1440 CE) was the coldest decade in Central Europe in the 15th century. The particularly cold winters and normal but wet summers resulted in a strong seasonal cycle that challenged food production and led to increasing food prices, a subsistence crisis, and a famine in parts of Europe. As a consequence, authorities implemented adaptation measures, such as the installation of grain storage capacities, in order to be prepared for future events. The 15th century is characterised by a grand solar minimum and enhanced volcanic activity, which both imply a reduction of seasonality. Climate model simulations show that periods with cold winters and strong seasonality are associated with internal climate variability rather than external forcing. Accordingly, it is hypothesised that the reconstructed extreme climatic conditions during this decade occurred by chance and in relation to the partly chaotic, internal variability within the climate system.

Comparison of CO2 From Coal Capture Processes and Valorisation Technologies

Coal is the most plentiful and evenly distributed fossil fuel worldwide. Based on current production, it is estimated that the reserves will last approximately 130 years. Its use worldwide has been increasing, mainly due to consumption by emerging countries. CO2 emissions generated by combustion and the repercussions of such on climate change support the view that it could no longer be used. CO2 capture may be the solution to continue using it, which would cater for the growing energy demand worldwide. The aim of this study is to compare different processes concerning CO2 capture that may be economically viable, ultimately showing that coal, a fossil energy source widely distributed around the world, can, as a result of using different CO2 capture processes, be used as a clean source of electricity. Hence, in places where geological hurdles may render the costs of CO2 storage considerably higher, since it might have to travel far, coal may be used for other purposes, thus valorising CO2 within the industrial sector. This research is focused on the technical and economic comparison of the most relevant CO2 capture projects designed in Spain using different existing technologies. The oxyfuel project in Ciuden (Leon, Spain), the IGCC Elcogas, precombustion CO2-capture project (Puertollano, Spain) and the postcombustion project in Carboneras (Almeria, Spain) will be analyzed in order to assess the options available to valorise captured CO2. Valorising captured CO2 may be an adequate solution in areas where, although CO2 capture is still possible, storage is not equally so, thus generating a further benefit. The possible uses of CO2 will be assessed in vegetable growing greenhouses, harnessing CO2 in vegetable life cycles. This will also be used in growing algae for subsequent biodiesel production. Both CO2 capture and valorising will eventually lead to the clean use of coal, which will thus enhance the level of self-supply, aiding the development of electric vehicles, which require large amounts of electricity, as well as improve the level of energy autonomy in countries around the world. Another type of fuel, biodiesel, will also be obtained, without this affecting international food prices.

Análisis y prospectiva del sector Desarrollo Rural y Seguridad Alimentaria Nutricional desde el enfoque de la Cooperación Española Internacional al Desarrollo

Esta investigación nace de la necesidad de aunar el máximo conocimiento sobre el sector Desarrollo Rural, Seguridad Alimentaria y Nutrición en la Cooperación Española, tanto desde un punto de vista teórico como práctico, que facilite, por un lado, precisar los límites que abarca el sector, conceptuales y de aplicación, mejorando la eficiencia y eficacia de las intervenciones en él, y por otro, conformar una prospectiva del mismo. La tesis propone una metodología de investigación-acción, puesto que por la propia posición de trabajo de la investigadora en la AECID y en el sector, esta es, a la vez, objeto y actora de la realidad vivida y del cambio a futuro. Para el trabajo de campo se ha contado con un importante grupo de expertos en la materia, que han participado en talleres de reflexión y en la encuesta Delphi, así como con una serie de entrevistas en profundidad. El requisito de contar con un marco teórico en el que se sustente el sector es esencial y el capítulo IV contempla este, partiendo de los antecedentes y marco normativo de la política de cooperación española, substancialmente la Ley de Cooperación Internacional para el Desarrollo, pasando por los principales instrumentos de planificación de esta política: Planes Directores, Estrategias sectoriales y Plan de Actuación Sectorial de Desarrollo Rural y Lucha contra el Hambre. Se puntualiza la cooperación reembolsable en el sector, y se repasan las principales actuaciones que han tenido lugar en el contexto internacional con especial hincapié en la crisis provocada por la subida del precio de los alimentos y las medidas más significativas que se tomaron para combatirla, pasando a continuación al proceso post-2015, los Objetivos de Desarrollo Sostenible y la posición española en él. En el marco conceptual se revisan términos tales como Derecho Humano a la Alimentación, Seguridad Alimentaria y Nutrición, Seguridad alimentaria, Seguridad alimentaria nutricional, Soberanía alimentaria, Seguridad alimentaria como Bien Público Mundial, Desarrollo Rural, Desarrollo Rural Territorial, Enfoque Territorial y Resiliencia, concluyendo este apartado con la búsqueda de las interrelaciones entre Seguridad alimentaria, Derecho Humano a la Alimentación y Desarrollo Rural Territorial. El capítulo termina con un breve repaso de lo que hacen en esta materia las principales agencias de Cooperación Internacional de los donantes más importantes del CAD. En el Marco de Aplicación se acomete una comparación de la evolución de la AOD en el marco temporal de la investigación, del 2000 al 2013, concedida al sector por la Cooperación Española en función de los distintos subsectores y también una comparativa de la ayuda otorgada por los principales donantes del CAD para este mismo periodo. Posteriormente se examinan las intervenciones centrales de la Cooperación Española en Derecho Humano a la Alimentación con la sociedad civil, con la FAO y con el relator especial de NNUU para el Derecho a la Alimentación, Seguridad Alimentaria Nutricional, destacando el Fondo España-ODM y el Programa Especial de Seguridad Alimentaria (PESA)y Desarrollo Rural Territorial , sobre el proyecto EXPIDER I y II (Experiencias de desarrollo local rural en América Latina) , y el proyecto PIDERAL ( Proyecto de políticas innovadoras de desarrollo de los territorios rurales en América Latina ) y tres intervenciones con enfoque regional como son :La Iniciativa América Latina y Caribe sin Hambre (IALCSH), la Estrategia Centroamericana de Desarrollo Rural Territorial (ECADERT) y la intervención de la Cooperación Española apoyando la Política Agraria de la CEDEAO. La investigación empírica esencialmente con un enfoque cualitativo, se examina y detalla en el capítulo VI, reflejándose las principales conclusiones de la misma en el capítulo del mismo nombre, tras haber contrastado las hipótesis formuladas y posteriormente cotejar las aplicaciones prácticas de la tesis y proponer posibles nuevas líneas de investigación. ABSTRACT This research stems from the need to combine the best knowledge about the Rural Development, Food Security and Nutrition sectors in Spanish Cooperation, both from a theoretical and practical point of view, that enables, on the one hand, to specify the limits that the sector covers, both conceptual and of implementation, improving the efficiency and effectiveness of interventions in it, and on the other, shape the future thereof. The thesis proposes a methodology of research-action, which is the AECID researcher´s own position in the sector, being at the same time, both researcher and participant of the reality experienced and future change. The field work benefitted from the support of a major group of experts in the field, who participated in reflection workshops, the Delphi survey and a series of in-depth interviews. The requirement for a theoretical framework that sustains the sector is essential and Chapter IV provides for this, starting with the background and legal framework of the policy of Spanish cooperation, essentially the International Development Cooperation Law, through the main instruments of policy planning: Master Plans; sectorial strategies; the Sectorial Action Plan for Rural Development; Fight against hunger. Refundable cooperation in the sector is specified, and the key actions that have taken place in the international context with special emphasis on the crisis caused by rising food prices and the most significant measures taken to combat it are reviewed. Then continuing with the post-2015 process, the Sustainable Development Objectives and the Spanish position in them. Conceptional framework terms such as Human Right to Food, Food Security and Nutrition, Food Security, Nutritional Food Security, Food Sovereignty, Food Security as a global public good, Rural Development, Rural Regional Development, Regional Approach and Resilience are reviewed, ending this section with the search for the interrelationship between Food Security, Human Right to Food and Rural Regional Development. The chapter ends with a brief overview of what the main agencies for International Cooperation of the major DAC donors do in this area. In the implementation framework, a comparison is provided of the evolution of the ODA within the time frame of the investigation, from 2000 to 2013, granted to the sector by the Spanish Cooperation in terms of the various subsectors and also a comparison is made of the support provided by the DAC's major donors for the same period. Subsequently the core interventions of Spanish Cooperation in the Human Right to Food with civil society, with FAO and the UN Special Rapporteur on the Right to Food, Food Security Nutrition are examined, highlighting the Spain MDG Fund and the Special Programme for Food Security (PESA) and Regional Rural Development on the EXPIDER I and II project (Rural local development experiences in Latin America), and the PIDERAL project (Innovative policy development project of rural areas in Latin America) and three regionally focused interventions such as: the Latin America and Caribbean without Hunger (HFLACI) Initiative, the Central American Strategy for Rural Development (ECADERT) and the intervention of the Spanish Cooperation to support the ECOWAS Agricultural Policy. Empirical research, essentially with a qualitative approach, is examined and detailed in Chapter VI, reflecting the main conclusions of the investigation in the chapter of the same name, after having contrasted the ideas put forward, and then later compares the practical applications of the thesis and proposes possible new lines of research.

RED vs. REDD: Biofuel Policy vs. Forest Conservation. Factor Markets Working Document No. 41, May 2013

This paper assesses the complex interplay between global Renewable Energy Directives (RED) and the United Nations programme to Reduce Emissions from Deforestation and forest Degradation (REDD). We examine the interaction of the two policies using a scenario approach with a recursive-dynamic global Computable General Equilibrium model. The consequences of a global biofuel directive on worldwide land use, agricultural production, international trade flows, food prices and food security out to 2030 are evaluated with and without a strict global REDD policy. We address a key methodological challenge of how to model the supply of land in the face of restrictions over its availability, as arises under the REDD policy. The paper introduces a flexible land supply function, which allows for large changes in the total potential land availability for agriculture. Our results show that whilst both RED and REDD are designed to reduce emissions, they have opposing impacts on land use. RED policies are found to extend land use whereas the REDD policy leads to an overall reduction in land use and intensification of agriculture. Strict REDD policies to protect forest and woodland lead to higher land prices in all regions. World food prices are slightly higher overall with some significant regional increases, notably in Southern Africa and Indonesia, leading to reductions in food security in these countries. This said, real food prices in 2030 are still lower than the 2010 level, even with the RED and REDD policies in place. Overall this suggests that RED and REDD are feasible from a worldwide perspective, although the results show that there are some regional problems that need to be resolved. The results show that countries directly affected by forest and woodland protection would be the most economically vulnerable when the REDD policy is implemented. The introduction of REDD policies reduces global trade in agricultural products and moves some developing countries to a net importing position for agricultural products. This suggests that the protection of forests and woodlands in these regions reverses their comparative advantage as they move from being land-abundant to land-scarce regions. The full REDD policy setting, however, foresees providing compensation to these countries to cover their economic losses.
