Publication Visualizing rural financial market research in Northern Vietnam through pictures(2003) Geppert, Meike; Dufhues, Thomas BernhardOne of the many tasks of financial market research is to develop client-oriented financial products. In order to ensure that the financial products reflect the necessities and preferences of the clients, profound participation of the target group throughout the whole research process is important. The use of pictures reduces problems of understanding and makes communication more interesting since everybody is now an insider in the discussion and can thus contribute his or her opinion. The use of pictures in research enhances participation and the research findings will be more target-group oriented. The extent to which the expense associated with using pictures in research ? which is not to be underestimated ? justifies the gains in terms of the information and data collected is rarely assessed. This article is addressed to researchers who investigate in similar situations and will offer them a basis of experience that they can take advantage of. The authors assume that information about the usefulness of the different techniques applied might be most interesting for other researchers. They conclude that the use of pictures in financial market research revealed some interesting results, albeit sometimes at quite a high cost. Nevertheless, the impact of supportive pictures on the quality of new knowledge is difficult to assess, since we have no way of answering the question of whether it would have been possible to obtain the same information without the suppor of pictures.Publication Möglichkeiten und Grenzen der Sekundärwalderhaltung im Bundesstaat Sucre, Venezuela - Brachewirtschaft, Agroforstsysteme und forstliche Nutzung in der kleinbäuerlichen Landwirtschaft -(2003) Valqui Haase, Alexis Holger; Heidhues, FranzHalf a billion people are considered as direct actors of tropical deforestation. Especially those, who live in the tropics in forest areas or nearby forests as peasants and landless people. They use and destroy the tropical forests by trying to secure the subsistence of their families. This study analysis the leading socio-economic and legal factors of the use and destruction of forest ecosystems in the small scale agriculture of the Paria Region, in the State Sucre, Venezuela. In the Paria Region the small scale agricultural systems secure their subsistence especially trough the cultivation of agricultural products in fallow systems and agroforestry systems. Following questions are treated: In which way does the agrarian reform law and the local land tenure as well as the forest law and the forest politics influence the protection of forests by peasants? How does the landuse systems contribute to the income and subsistence assurance of peasant families as well as to deforestation? Which functions does the forests fulfil from the point of view of the peasants and what benefit could they realise from the forests? A quantitative and qualitative approach was chosen. Standardised survey as well as econometric and statistical data analysis methods, like Cluster analysis and logistical regression, are combined with semistructured interviews and qualitative analysis methods. Conclusions: Forests are seen in the agrarian reform law as well as at community level primarily as a reserve for agricultural land. The "agrarian occupation" which follows the principle, land is owned by them who use it, is an instrument to avoid land concentration. But in countries like Venezuela it has also deforestation as consequence, where forests are seen as land that is not in use. The fact that forests are seen as land that is not in use or even useless land is reinforced by the restriction which peasants are confronted with, due to the forest law and it's implementation, when they wanted to use the forests for income generation. Also the function of the forests as supplier of subsistence goods for the families is loosing importance because of the substitution of this goods by industrial ones. This restriction and development has the consequence that peasants become more and more "disinterested forests managers". The comparison of the fallow systems and agroforestry systems of the Paria Region shows that agroforestry systems are relative better from the view of income generation and forests conservation. They have a lower land productivity, but they have a relative high work productivity and generated better distributed income. On the other side they are less forest destructive. In most of the cases they can be even seen as secondary forests.Publication Rural financial markets under transformation : a study on credit supply and demand in Romania's private farm sector(2003) Breitschopf, Barbara; Heidhues, FranzThe study analyses the credit supply and demand of farms in the rural area of Romania. A qualitative analysis describes and outlines the problems and bottelnecks the financial and agricultural sector are facing during the transformation period. A detailed quantitative analysis gives the credit supply and demand. Based on a multiple non-linear regression the demand function is derived. Taking into account the special situation in transition countries, the collateral requirements and its evaluation process, the price and market uncertainties as well as the orientation of the farm household on utility maximization, results in different capital demand structures. The credit supply of the financial institution with variing transactions costs is derived from a partial profit function. The results show, that a strong focus of the financial institutions on collateral prevents a matching of credit supply and demand since the farm households are not willing to provide collateral when their total assets are rather limited. A higher screening effort of the banks increases transaction cost but also reduces the default risk.Publication Towards demand-driven financial services in Northern Vietnam: a participatory analysis of customer preferences(2003) Dufhues, Thomas BernhardAnalyzing secondary and primary data, this paper suggests a shift in national development policies from solely promoting rural credit to supporting savings activities. The household data are econometrically analyzed applying the Conjoint Analysis (CA). The CA gave valuable insights into how to improve outreach of formal financial institutes (FFIs) by adapting the credit products to client preferences and revealed an unattended demand for savings instruments. Due the enormous credit outreach of the FFIs in Vietnam, it would be more efficient to launch a credit consolidation policy and to implement a reliable and sustainable deposit collection system at the village level. However, in national policymaking a paradigm change must take place and the capability of rural households to save needs to be recognized by policy-makers.Publication Regional development perspectives in Vietnam: insights from a 2002 provincial social accounting matrix (SAM)(2004) Heidhues, Franz; Breisinger, ClemensGrowing regional disparities in Vietnam have encouraged plans to extend the national Comprehensive Poverty Reduction and Growth Strategies (CPRGS) to the provincial level. The northern mountainous province of Son La has distinctive development perspectives. It was selected as the site of Vietnam?s planned biggest dam and hydroelectric power plant. Large-scale infrastructure investments are expected to contribute to economic growth and poverty reduction in the region. The impacts of these investments on the regional economy can be assessed with a multiplier model based on a regional social accounting matrix (SAM). In this paper, we present a 2002 SAM for Son La. To shed light on the socioeconomic situation, we review insights from this detailed database. A SAM-based multiplier model is then put forward to examine linkages within the provincial economy and to present first results of demand-side effects of infrastructure investment in the local construction sector.Publication Assessing participation in agricultural research projects: an analytical framework(2004) Neef, Andreas; Neubert, DieterRecent discourse in the field of agricultural research has focused on how to assess and optimize the use of participatory approaches. In this paper, we propose a new Analytical Framework for the Assessment of Participatory Agricultural Research (AFAPAR) that seeks to evaluate participatory research elements along different dimensions and over several research phases and thus takes into account the complexity and dynamics of agricultural research projects. Empirical data from a long-term collaborative research program on ?Sustainable Land Use and Rural Development in Mountainous Regions of Southeast Asia? (The Uplands Program ? SFB 564) are used to explore the potential and shortcomings of AFAPAR. Findings suggest that while there is a need for further refinement, the analytical framework provides a sound basis for a differentiated assessment of participatory approaches in agricultural research that goes beyond the existing one-dimensional typologies of participatory research with their inherent claim of ?the more participation, the better?.Publication Media supported communication in agricultural extension and participatory rural development in Northern Thailand(2004) Fischer, IsabelThe inhabitants of Northern Thailand, Thais as well as the members of the different ethnic groups, the so-called hill tribes, face a variety of very complex problems that range from natural resources conflicts via human rights issues to health problems. All in all, those issues constitute the initial point of departure for every extension, development and research activity, regardless of whether carried out by governmental, non-governmental organizations and/or other agencies. In order to analyze the current extension situation in Northern Thailand, field research was carried out in collaboration with different governmental and non-governmental organizations. Insights were gained into major areas of operation as well as currently used extension methods and media (especially picture supported communication tools) that are used in extension and rural development work, particularly when the target group is illiterate. Three organizations were observed in more detail and will serve as case studies. The paper presents Methods and Media Used by Different Organizations as well as major Criteria for Using Media in Extension and Development Work. Furthermore, the Application of Criteria for Different Methods and Media will provide the basis for the discussion of major potentials and limitations of currently used media in comparison to the Flannelgraph method, which was chosen as a major methodological tool of reference. In summary, it appears that the extension situation in Northern Thailand is too heterogeneous to identify the one ?right? extension approach. The use of media and the choice of extension methods depend on specific financial, logistic, methodological and cultural criteria as well as further issues, such as infrastructure, target group and the costs of the respective tool. In order to increase the potential and decrease the limitations of the currently used methods, the organizations have to concentrate on a better use of the already existing means as well as the improvement of those factors that are not fully used at the moment.Publication Constraints and potential of livestock insurance schemes: a case study from Vietnam(2004) Fischer, Isabel; Dufhues, Thomas Bernhard; Lemke, UteLivelihood systems of poor rural households are often so fragile that a small misfortune can destabilize households for years. Strategies for coping with risk include informal mutual aid agreements and/or formal microinsurance schemes. In developing countries, insurance markets are usually underdeveloped.Nevertheless, if the development path is supported by strong structures and institutions, anonymous markets will, over time, replace informal insurance networks as they are more efficient. In Vietnam, livestock is an important household income source and has additional non-economic functions in the households. For a long time, rural financial institutions in Vietnam financed only a small array of agricultural investments, but these frequently included livestock purchase. The absence of off-farm investment possibilities further promotes investment in livestock production. Failure of an investment, especially when loan-funded, can leave a household in an extremely vulnerable position. Livestock death is considered to be a major factor contributing to poverty. Farmers using credit to purchase livestock face two risks at once: (1) loss of the livestock due tovdisease and subsequently (2) failure of investment. Farmers would like to reduce the uncertainty, but a broad-based livestock insurance scheme does not exist in Vietnam. There are only a few formal and semi-formal schemes with very limited outreach. Thus, access to formal insurance is almost non-existent, and farm households have to rely mainly on informal mutual aid schemes within their social networks to reduce their risks. The objective of this paper is to contribute to the discussion on the general feasibility of a livestock insurance scheme in Vietnam. In this context, the demand for and supply of livestock insurance schemes is discussed. Quantitative (N=322) and qualitative data collection took place between 2001 and 2004. The quantitative data comprise cross-sectional household-level data from three different districts in Northern Vietnam. Four different types of insurance providers were selected for analyzing the supply side: 1. Insurance tied to credit within a state-owned company; 2. Insurance tied to credit within a development project; 3. A state-owned insurance company (which collapsed); 4. A private insurance company. By selecting these different insurance providers, the range of livestock insurance types offered in Vietnam was covered. The main result is that provision of sustainable livestock insurance is hampered principally by unreliable data on livestock mortality and by premia that are set politically at a low evel.Publication On the distribution and adoption of genetically modified seeds in developing countries(2004) Basu, Arnab; Qaim, MatinGiven the proprietary nature of most genetically modified (GM) seed technologies, the question arises as to how farmers in developing countries can gain proper access to these innovations. Based on empirical observations, a theoretical model is developed which focuses on farmers? adoption decisions in response to the pricing strategies of a foreign patent holder and the government. If the government is able to commit to the announced policy, subsidizing the use of traditional seeds can increase coverage of GM technology and domestic welfare. The possibility of the government obtaining a license to distribute GM seeds domestically through a transfer to the monopolist is also considered.Publication Sozio-ökonomische Beurteilung von Innovationen: Untersuchungen über die Innovationenakzeptanz auf Betriebs-Haushaltsebene in Niger(2004) Haigis, Jörg; Heidhues, FranzThe presented research study deals with the question, which socio- economic and personal characteristics of the heads of household as the main decision persons within the nigerian farm-household-systems influence significantly their adoption behaviour. Simultaneous innovation adoption of thirteen selected different new technologies were in the focus of the study. The study emphasizes especially the time of the adoption state, which could be observed for all considered innovations by all investigated heads of household at a certain reference point of time. The reference point of time is the year 1995. The analysis of the selected farm-household-systems produced an erratic use for most of the thirteen considered innovations over time until first adoption. Simultaneously the adoption behaviour of the household chiefs show a distinct regional emphasis in terms of the adopted technology type. These emphasis merely reflect rudimentary the climatical site conditions in the republic of Niger. They correspond only apparently the climate gradient of the research sites. At drier sites there the households favour particularly resource saving innovations, for which an internal input availability exist. In contrast the farmers put their emphasis on the adoption of labour-saving technologies at the climatical favourable sites. With a closer look there are less the climatical conditions which influence this behaviour than local particularities, especially within the farm-household-systems. Above all this particularities are the limited access of agricultural active women to use the household labour force for the work on their fields. Exclusively women cultivate groundnuts in this region. Thereby the groundnut cultivation is the main activity within the crop production. Groundnut production is predominantly for the women a profitable business through processing. Because of these circumstances in this region exist a well funded demand for wage labour to prepare groundnut fields with animal-drawn implements. The temporal discontinuity of an adopted innovation is found especially for external and yearly obtainable inputs. Accordingly the cumulative behaviour of each household chief show a variable mixture of actual, former and never occurred adoption. Five adopter groups can be found within this complex appearing behaviour situation with the help of cluster analysis methods. The group-specific adoption behaviour rises in an order from low until especially innovative. Except of the low innovative household chiefs, each adopter group show a significant technological emphasis in terms of the type of adopted technologies. This emphasis coincide with the regional one. The order of the adoption behaviour does not correspond with the climate gradient. Neither a comparison of the identified adopter groups with variance analysis nor the econometric analysis using a multi-nomial logit-model resulted in a clear finding that personal or socio-economic characteristics of the household chief influence significantly their adoption behaviour. In fact the results of the logistic regression confirm a high dependency from the location for the observable adoption behaviour. The distinct regional division between high and special innovative household heads on the one side opposite to all others indicates a significant influence on the individual adoption behaviour by local and regional factors. But the question could not be resolved in the context of this farm-household-system based study, wherein these factors are in detail. The adoption of technological innovations shows not only a distinct regional emphasis and a partly temporal discontinuity but also it is characterised by an adaptation in terms of the spatial use of adopted technologies. The farmers cultivate their fields not homogeneously over the whole field area. Rather they apply a kind of site-specific cul¬tivation. In doing so they adapt each cropping measure to the site conditions changing on a small-scale within in a field. This spatial adaptation includes also the adopted innovations. The observable adoption behaviour of the household chiefs points up the basic willingness to use new technologies and with it the change of the previous traditional cropping methods. The identified particularities of the innovation adoption confirm on the one hand the significant adaptation ability of the farmers to the particular local and temporal conditions. On the other hand these particularities are an indication of the inadequate adaptation of the recommended innovations. As a result the success of further efforts to modernise the nigerian agricultural farms depends greatly from the stronger consideration of these particularities in the future development and diffusion of new technologies.Publication Comparative advantage of Vietnam's rice sector under different liberalisation scenarios: a policy analysis matrix (PAM) study(2004) Nguyen, Manh Hai; Heidhues, FranzThe rapidly changing global economic environment and domestic economic reforms in Viet-nam have brought the issue of comparative advantage of the rice sector to the forefront. In recent years, Vietnam has had to compete in an increasingly competitive rice export market. This paper examines the fluctuations in the comparative advantage of Vietnamese rice production based on different scenarios of trade liberalisation and economic reform in Viet-nam. To do this, a Policy Analysis Matrix (PAM) was used in conjunction with an econo-metric model. The study involved simulation of a large number of scenarios of trade liberalisation and macroeconomic reform, using variations in a single factor and in a group of factors such as product price and input costs, i.e., the price of imported fertilisers, land, water and labour costs, etc. The empirical results show that in 1998 (the baseline scenario), the comparative advantage in rice was relatively high and that the use of domestic resources ? i.e., land, labour and water ? was efficient in economic terms. The estimated DRC elasticities in respect of the world rice price and the shadow exchange rate in 1998 showed a considerably improved com-parative advantage. The estimated DRC elasticities for land rent, the social costs of labour, the import price of fertilisers and irrigation water charges were small in absolute values indi-cating small and negative impacts on comparative advantage with a rise in these prices. The results of sensitivity analyses revealed that the comparative advantage of rice is very sensitive to changes in its export price. In addition, the exchange rate and land rent are also important determinants of the rice sector?s comparative advantage in Vietnam. Other empirical results show that Vietnam is still likely to retain its comparative advantage in rice production in the next decade; however, its comparative advantage might be seriously affected or even dis-appear entirely if Vietnam is exposed to a number of unfavourable economic conditions simultaneously. The major recommendation of this paper is that production should be diversified, with appropriate agricultural policy support, within a broader framework of macroeconomic transformation and trade liberalisation.Publication Debt position of developing countries and new initiatives for debt reduction: a panel data fixed effects estimation of the impacts of the HIPC initiatives(2005) Houssou, Nazaire; Heidhues, FranzIn September 1996, the World Bank and the International Monetary Fund launched the Heavily Indebted Poor Countries Initiative (HIPC). This initiative was endorsed by 180 governments around the world as an effective and welcome approach to help poor, severely indebted countries reduce debt as a part of the overall poverty reduction strategy. Three years later, the initiative was enhanced to provide for faster, broader and deeper debt relief. Using a panel data fixed effect estimation, this study assesses the achievements of the first and second HIPC initiatives and explores further areas of intervention that might help the HIPCs graduate from debt rescheduling and achieve sustainable growth and poverty alleviation. Despite moderate achievements of the HIPC measures so far, this paper argues in favour of a HIPC III initiative. Much more relief is needed to link debt reduction to poverty alleviation if the expectations raised by the HIPC initiatives are to become reality.Publication Außerlandwirtschaftliche Diversifikation im Transformationsprozess. Diversifikationsentscheidungen und -strategien ländlicher Haushalte in Slowenien und Mazedonien(2005) Möllers, Judith; Heidhues, FranzNon-farm rural diversification is gaining prominence in the debate on rural development since the end of the 1990s. The expansion of non-farm employment and the diversification of incomes are important policy objectives because they offer a solution to the employment and structural problems of a shrinking agricultural sector. Development policies focusing on the rural non-farm sector aim at offering employment options and reducing urban migration. They can contribute to poverty reduction, economic growth and a more equal income distribution. This research is based on a household survey including 240 randomly selected rural households in Slovenia and Macedonia. Since empirically based insights on diversification dynamics in transition countries are hardly available, the objective of this research is to contribute to filling this gap. The analysis focuses on diversification strategies and determinants of the decision-making process of rural people in regard to non-farm employment. The methodology combines an inductive and deductive approach with qualitative and quantitative components. For the statistical analysis primarily logistic regression models are applied. The results show that rural households in the research area are highly dependent of non-farm incomes. As expected the poverty risk between the two countries differs: Rural household incomes in Macedonia are less equally distributed. Decomposed Gini-coefficients based on non-farm incomes point at their positive effect on the income distribution. The analysis of diversification strategies indicates that coping strategies as well as risk-minimising strategies prevail. Accumulation strategies, which point at demand-pull dynamics and entrepreneurship, are less common. Attitudes towards agriculture seem to influence diversification decisions in particular. While attitudes towards non-farm activities are predominantly positive, they vary towards agriculture. Negative attitudes towards agriculture are wide-spread among the younger generation. In the age group from 16 to 25 years the proportion of negative attitudes is high in both countries, but the share in Macedonia with 50% is twice as high as in Slovenia. Important constraints of diversification in Macedonia are the non-farm labour market, low wages, insecurity and late wage payments. In both countries capital and credit availability are named as the most important reasons for not starting a business in the non-farm sector. The pressure to adapt income strategies is lower in Slovenia in general. When looking at individual employment strategies it becomes apparent that in both countries there is a declining trend of agricultural and combined employment while non-farm employment alone is increasing. In Slovenia the high level of diversification at the household level is stabilising while the structural problems in the agricultural sector persist. In contrast, the level of diversification in Macedonia is expected to further increase even though the willingness to give up agricultural activities altogether is significantly higher than in Slovenia. A promotion of the rural non-farm sector is an important policy objective as non-farm employment has a positive impact on rural incomes, particularly in poorer households. The effect of non-farm incomes on the income distribution is positive. This underlines the importance of the non-farm sector as an essential component of a poverty-oriented rural development policy. In the long term rural development policies should aim at overcoming the unfavourable small-scale agricultural structure which is the main cause of distress-pushed diversification ? particularly if full-time employment in the non-farm sector is not available. For this it is essential to support education and knowledge-building, and to offer expert advice. The intention should be to enhance entrepreneurship, creativity and the willingness and ability to take economic risks. Furthermore, the success of any effort to improve rural development policies depends on locally developed strategies, since the heterogeneity of the non-farm sector calls for decentralised political concepts. With these prerequisites the non-farm sector will be able to absorb labour released from agriculture, and the necessary structural adjustment of the agricultural sector can take place.Publication Outreach of credit institutes and households' access constraints to formal credit in Northern Vietnam(2005) Dufhues, Thomas; Buchenrieder, GertrudAbstract Most policy and research interest regarding rural credit markets revolves around the perception that poor households in developing countries lack access to credit, which is believed to have negative consequences for household welfare. An important feature of the rural credit market is that access to credit is easier for some groups than for others. The Vietnamese government supplied credit on preferential terms, particularly to rural households, throug state-owned financial intermediaries. The share of the informal sector was thus considerably reduced from 78% (1992/93) of all outstanding loans to 54% (1997/98) in favor of the formal sector. However, there is evidence from other developing countries that credit constraints persist despite the expansion of rural finance. Hulme and Mosley (1996) state that there is increasing evidence that the poorest 20% of the population are excluded from rural credit programs. Thus, even in Vietnam the question remains: did the Vietnamese government succeed in reaching the poor, or do groups of people exist who are still access-constrained? Quantitative (N=260) and qualitative data collection took place between March 2000 and 2001. The quantitative data comprise cross-sectional household-level data from two different districts in Northern Vietnam. The poverty outreach of formal rural lenders was analyzed using Principal Component Analysis, while access to formal credit was investigated using a binary logit analysis. The poverty outreach of the formal lenders is quite satisfactory since about 50% of all predominantly poor rural households have access to formal credit. However, the poorest households are seldom clients of formal lenders. Yet, it is not their extreme general poverty that determines their access to formal credit. The results indicate that only certain aspects of poverty, e.g. low quality of housing, have an important influence on access to formal credit in Vietnam. The poorest households simply have much less demand for formal credit. Offering new credit products would only slightly improve the credit coverage of poorer households. More promising would be a specialized pro-poor extension service to widen the scope of their investment ideas and possibilities, combined with general improvement of the infrastructure. All in all, the most appropriate tool to incorporate poorer households into the formal financial system would be mobilization of savings. Nevertheless, the number of access-constrained households is surprisingly low. One reason for the low number is the weakening or eradication of former access constraints. Some acces barriers do still exist, e.g. towards ethnic minorities or female-led households. To reduce these access barriers, the actions to be taken should be catering to the specific needs and the circumstances of those households that lack access.Publication Micronutrient malnutrition and the impact of modern plant breeding on public health in India: How cost-effective is biofortification?(2006) Stein, Alexander J.; Qaim, MatinMillions of people worldwide suffer from micronutrient malnutrition or ?hidden hunger?. The related deficiencies can have devastating consequences for the life, health and well-being of the affected individuals, but they may also perpetuate a vicious circle of undernutrition, low economic productivity and poverty. Hence, in many developing countries vitamin and mineral deficiencies are public health problems of primary concern. While economic development and rising incomes can only address undernutrition in the long run, conventional approaches also have weaknesses of their own. Therefore, ?biofortification? may be a promising intervention. The idea is to breed food crops for higher micronutrient content, which can be done through cross-breeding or genetic engineering. Targeting staple crops that fortify themselves has several advantages: the enriched crops simply follow the normal food chain and are eaten by the poor in bigger quantities. Moreover, the underlying germplasm of micronutrient-rich crops only needs to be developed once and can then be used around the world ? and farmers can grow and reproduce biofortified crops year on year and share the micronutrient-dense seeds. Therefore, the initial investments in R&D of biofortification can be followed by a continuous stream of benefits that accumulates over time and space, which suggests that biofortification can be a very cost-effective intervention. However, a more rigorous and comprehensive assessment of biofortification is still outstanding. This book has been written to narrow this knowledge gap and to offer a sound basis for future research and policy decisions regarding biofortification ? covering both, crops that are produced through conventional breeding and genetically modified organisms (GMOs). For this ex ante evaluation of biofortification, an impact assessment of five different crops (iron-rich rice and wheat, zinc-rich rice and wheat and beta-carotene-rich Golden Rice) has been done for India to determine their effectiveness. The main contribution of this study lies in the development of a methodology that reproduces the whole sequence of effects between the cultivation of the micronutrient-rich crops and their ultimate health impacts, taking into account various micronutrient levels in the crops, different rates of adoption and acceptance, and the ensuing improvements in individual nutrition status. To this end in this book the disability-adjusted life years (DALYs) framework has been refined and applied to determine the disaggregate burden of disease of iron deficiency anaemia (IDA), zinc deficiency (ZnD) and vitamin A deficiency (VAD) in India. The assessment of the potential impact of the biofortified crops has been complemented by an economic evaluation, because mere effectiveness is a poor guide to policy making when resources are limited. Therefore, a cost-effectiveness analysis (CEA) and a cost-benefit analysis (CBA) have been carried out for each of the crops to determine their efficiency and their overall social profitability. The attributable costs of the R&D for the crops as well as the costs for related dissemination and extension activities within India have been juxtaposed to the expected health benefits. The resulting cost-effectiveness measure ($/DALY saved) has been compared to alternative micronutrient programmes and to benchmarks of international organisations for assessing public health interventions. By attaching a minimum value to each DALY saved, the benefits of biofortification were translated into monetary terms to calculate a lower bound of the social rates of return of the crops. These economic indicators could then be compared to those of other agricultural technologies. While conventionally bred biofortified crops are less contentious, genetically modified crops (GM crops) and, thus, the transgenic Golden Rice are controversially discussed in the ongoing debate about plant biotechnology. Therefore, related issues are discussed in more depth in special sections of this book, where the validity of common claims about Golden Rice is scrutinized. The study concludes that biofortification has the potential to help control vitamin and mineral deficiencies in a lasting and sustainable way ? even though the commitment and the support of key stakeholders may be necessary to achieve its full impact. The various economic analysis have also shown that biofortification promises to be a very cost-effective, efficient and socially profitable intervention, both if compared to alternative public health measures and if compared to other agricultural innovations. Nevertheless, to control micronutrient deficiencies, the importance of a more comprehensive strategy is underlined; in such a strategy other micronutrient interventions like targeted supplementation, fortification, dietary diversification, nutrition education and poverty reduction may all have a role to play.Publication Agricultural sciences in upland Northern Vietnam : situating research in a dynamic environment(2006) Friederichsen, RupertThis paper aims to provide an introductory overview over the socio-cultural context of Northern Vietnam to agricultural researchers. The paper focuses on the interplay between Vietnam?s lowlands and the uplands to specify what makes the Northern uplands a distinct region; as an object of empirical agricultural research and as a context of application of research results. The paper reviews the developments of selected social institutions from pre-colonial times to the current era of ?renovation?. First, developments in Vietnam?s legal and administrative structures are outlined. Second, education and higher education, particularly the agricultural sciences, are discussed. The third and main part elaborates on social, political, and economic specifics of the Northern Uplands. It is suggested that the relationship between formal and informal institutions is crucial for understanding the dynamics of contemporary uplands Vietnam, particularly in the given multi-cultural situation.Publication Potential impacts of iron biofortification in India(2006) Bhutta, Zulfiqar A.; Stein, Alexander J.; Qaim, Matin; Meenakshi, J. V.; Nestel, Penelope; Sachdev, H. P. S.Iron deficiency is a widespread nutritional problem in developing countries, causing impaired physical activity and cognitive development, as well as maternal mortality. Although food fortification and supplementation programmes have been effective in some countries, their overall success remains limited. Biofortification, that is, breeding crops for higher micronutrient content, is a relatively new approach. We propose a methodology for ex-ante impact assessment of iron biofortification, which builds on disability-adjusted life years (DALYs) and a large household data set. Our analysis of iron-rich rice and wheat in India indicates sizeable potential health benefits. The cost-effectiveness of iron biofortification compares favourably with other interventions.Publication Can genetic engineering for the poor pay off? : an ex-ante evaluation of Golden Rice in India(2006) Qaim, Matin; Sachdev, H. P. S.; Stein, Alexander J.Genetic engineering (GE) in agriculture is a controversial topic in science and society at large. While some oppose genetically modified crops as proxy of an agricultural system they consider unsustainable and inequitable, the question remains whether GE can benefit the poor within the existing system and what needs to be done to deliver these benefits? Golden Rice has been genetically engineered to produce provitamin A. The technology is still in the testing phase, but, once released, it is expected to address one consequence of poverty ? vitamin A deficiency (VAD) ? and its health implications. Current interventions to combat VAD rely mainly on pharmaceutical supplementation, which is costly in the long run and only partially successful. We develop a methodology for ex-ante evaluation, taking into account the whole sequence of effects between the cultivation of the crop and its ultimate health impacts. In doing so we build on a comprehensive, nationally representative data set of household food consumption in India. Using a refined disability-adjusted life year (DALY) framework and detailed health data, this study shows for India that under optimistic assumptions this country?s annual burden of VAD of 2.3 million DALYs lost can be reduced by 59.4% hence 1.4 million healthy life years could be saved each year if Golden Rice would be consumed widely. In a low impact scenario, where Golden Rice is consumed less frequently and produces less provitamin A, the burden of VAD could be reduced by 8.8%. However, in both scenarios the cost per DALY saved through Golden Rice (US$ 3.06-19.40) is lower than the cost of current supplementation efforts, and it outperforms international cost-effectiveness thresholds. Golden Rice should therefore be considered seriously as a complementary intervention to fight VAD in rice-eating populations in the medium term.Publication Vitamin A and iron consumption and the role of indigenous vegetables: a household level analysis in the Philippines(2006) Weinberger, Katinka; Qaim, Matin; Ecker, Olivier; Hönicke, MireilleMicronutrient malnutrition is a public health problem in many regions of the developing world. Severe vitamin A and iron deficiencies are of particular concern due to their high prevalence and their serious, multiple health effects on humans. This paper examines dietary patterns and nutrient intakes, as well as their socioeconomic determinants among households in the Philippines. Since promotion of indigenous vegetables is often considered as an avenue to reduce micronutrient malnutrition, special emphasis is placed on analyzing the contribution of this particular food group to household vitamin A and iron intakes. We use a sample consisting of 172 resource-poor households located in peri-urban areas of Laguna Province. A 24-hour food consumption recall allows for detailed, meal-specific examination of diets. Results of the dietary analysis suggest that fish is of major importance for vitamin A and iron intakes. But also vegetables, and especially indigenous vegetables, play an essential role for balanced household diets. In order to determine socioeconomic factors influencing vitamin A and iron intakes, we employ an econometric model, which shows that deficiencies are strongly associated with low household incomes and poverty. Thus, poverty alleviation will help reduce the problem of micronutrient malnutrition in the medium and long run. However, in the interim, more targeted interventions will be needed. Our results suggest that promotion of indigenous vegetables can play a role in this respect, especially among the poor, who can often not afford sufficient amounts of animal products.Publication Land property, tenure security and credit access: a historical perspective of change processes in China(2006) Jia, Xiangping; Piotrowski, StephanThe North China Plain is the country?s granary: most of wheat and maize is supplied by this region in the northeast of China. Intensity of agricultural production has risen sharply in the last decades and the negative environmental effects like water scarcity, salinization and nitrate contamination have been widely acknowledged. In the wake of the country?s rapid economic development it becomes at the same time more and more urgent to narrow the gap between the well-being of the urban and rural population. In order to better understand the paths that lead to this present dilemma, this paper provides a historical overview of the development of the land and water markets and the rural financial system. It highlights the linkages and reciprocal restraints between these three sectors and gives some conclusions and policy recommendations on how to proceed in order to further a more sustainable development in the North China Plain. Apart from literature review, data from an original farm household survey, conducted by the authors, is used to substantiate the arguments put forth in this paper.
