Role of Crop Research and Development in food Security of Africa

Food security is the main concern in Africa as the production and productivity of crops are under continuous threat. Indigenous crops also known as orphan- or as underutilized- crops provide key contributions to food security under the present scenario of increasing world population and changing climate. Hence, these crops which belong to the major categories of cereals, legumes, fruits and root crops play a key role in the livelihood of the resource-poor farmers and consumers since they perform better than the major world crops under extreme soil and climate conditions prevalent in the continent. These indigenous crops have the major advantage that they fit well into the general socio-economic and ecological context of the region. However, despite their huge importance, African crops have generally received little attention by the global scientific community. With the current production systems, only a fraction of yield potential was achieved for most of these crops. In order to devise strategies towards boosting crop productivity in Africa, the current production constraints should be investigated and properly addressed. Key traits known to increase productivity and/or improve nutrition and diverse conventional and modern crop improvement techniques need to be implemented. Commitments in the value-chain from the research, production, marketing to distribution of improved seeds are required by relevant national and international institutions as well as African governments to promote food security in a sustainable manner. The review also presents major achievements and suggestions for stakeholders interested in African agriculture.

About DNA databasing and investigative genetic analysis of externally visible characteristics: A public survey.

During the last decade, DNA profiling and the use of DNA databases have become two of the most employed instruments of police investigations. This very rapid establishment of forensic genetics is yet far from being complete. In the last few years novel types of analyses have been presented to describe phenotypically a possible perpetrator. We conducted the present study among German speaking Swiss residents for two main reasons: firstly, we aimed at getting an impression of the public awareness and acceptance of the Swiss DNA database and the perception of a hypothetical DNA database containing all Swiss residents. Secondly, we wanted to get a broader picture of how people that are not working in the field of forensic genetics think about legal permission to establish phenotypic descriptions of alleged criminals by genetic means. Even though a significant number of study participants did not even know about the existence of the Swiss DNA database, its acceptance appears to be very high. Generally our results suggest that the current forensic use of DNA profiling is considered highly trustworthy. However, the acceptance of a hypothetical universal database would be only as low as about 30% among the 284 respondents to our study, mostly because people are concerned about the security of their genetic data, their privacy or a possible risk of abuse of such a database. Concerning the genetic analysis of externally visible characteristics and biogeographical ancestry, we discover a high degree of acceptance. The acceptance decreases slightly when precise characteristics are presented to the participants in detail. About half of the respondents would be in favor of the moderate use of physical traits analyses only for serious crimes threatening life, health or sexual integrity. The possible risk of discrimination and reinforcement of racism, as discussed by scholars from anthropology, bioethics, law, philosophy and sociology, is mentioned less frequently by the study participants than we would have expected. A national DNA database and the widespread use of DNA analyses for police and justice have an impact on the entire society. Therefore the concerns of lay persons from the respective population should be heard and considered. The aims of this study were to draw a broader picture of the public opinion on DNA databasing and to contribute to the debate about the possible future use of genetics to reveal phenotypic characteristics. Our data might provide an additional perspective for experts involved in regulatory or legislative processes.

Jatropha mahafalensis for rural energy supply in south-western Madagascar?

In many parts of the eastern African region wood-based fuels will remain dominant sources of energy in coming decades. Pressure on forests, especially in semi-arid areas will therefore continue increasing. In this context, the role of liquid biofuels as substitutes for firewood and charcoal, to help reducing pressure on woody biomass and contributing to a better energy security of rural communities, has remained controversial among researchers and practitioners. At household level, the economic and technical feasibility of straight vegetable oil (SVO) was assessed mainly on Jatropha curcas, with unpersuasive results. So far nothing is known about the suitability as an energy carrier of Jatropha mahafalensis Jum. & H. Perrier, the only endemic representative of the Jatropha genus in Madagascar. This paper explores the potential of this plant as a biofuel feedstock in the agro-pastoral area of Soalara, in the semi-arid south-western part of Madagascar. Only hedge-based production was considered to rule out competition over land with food crops. Yield data, the length of currently existing hedges and energy consumption patterns of households were used to assess the quantitative potential and economic viability of J. mahafalensis SVO for lighting and cooking. Tests were conducted with cooking and lighting devices to assess their technical suitability at household level. The paper concludes that J. mahafalensis hedges have some potential to replace paraffin for lighting (though without much economic benefit for the concerned households), but not to replace charcoal or firewood for cooking. The paper recommends that rural energy strategies in similar contexts do not focus only on substituting current fuels with SVO, but should also take into consideration other alternatives. In the case of cooking, there seems to be substantially more potential in increasing the efficiency of current fuel production and consumption technologies (kilns and stoves); and in the case of lighting, solutions based on SVO need to be compared against other options such as portable solar devices.

Ernährungssicherheit in der Schweiz

Viele Länder verankern die Versorgungs- oder Ernährungssicherheit als staatspolitisches Ziel in ihrem Grundgesetz. Neuerdings wird auch das Recht auf Nahrung und auf die Erfüllung weiterer Grundbedürfnisse aufgeführt. Das Schweizer Parlament hat darüber hinaus sogar den Grundsatz der Ernährungssouveränität im Landwirtschaftsgesetz verankert. Die zur Förderung dieser Ziele genannten Aufgaben und Eingriffsrechte des Staates sind jeweils unterschiedlich und unterschiedlich präzise formuliert. Dabei gibt es für jedes Land eigentlich nur zwei Möglichkeiten zur Ernährung: Inlandproduktion und Einfuhr. Eine zusätzliche Option ist die Bildung von Nahrungsmittelreserven zur Überbrückung von Versorgungsengpässen. Die Schweiz benützt und fördert alle drei Möglichkeiten zu ihrer Ernährungssicherheit, im Wesentlichen mit vier Politiken: Versorgungs-, Aussenwirtschafts-, Agrar- und Entwicklungspolitik. Bei Störungen sollen die durch Grenzabgaben finanzierten Pflichtlager während rund sechs Monaten die Inlandnachfrage sichern. Die Optimierung und die Abstimmung unter den verschiedenen Sektorpolitiken, welche unter Berücksichtigung der internationalen Rahmenbedingungen eine grösstmögliche Ernährungssicherheit herbeiführen, gehört zu den Kernaufgaben jedes Staates. Die Umsetzung der genannten Sektorpolitiken ist jedoch in der Praxis nicht immer kohärent, geschweige denn konfliktfrei. Dieser Artikel beschreibt zunächst die internationalen rechtlichen und ökonomischen Parameter für die Schweizer Versorgungspolitik und ihre Beziehung zur Wirtschaftsfreiheit im Allgemeinen, und speziell auf ihre Zweckmässigkeit hinsichtlich der Ernährungssicherheit. Die Analyse der Wechselwirkungen und der Konflikte bei der Umsetzung zeigt, dass die Schweizer Ernährungssicherheitspolitik (food security) in Wirklichkeit eine Politik zur einheimischen Produzentensicherheit ist (farm security). Den Abschluss bilden einige Vorschläge zur Minderung der sektorpolitischen Inkohärenzen und der festgestellten negativen Auswirkungen der Agrarpolitik auf die Schweizer und globale Ernährungssicherheit.

Negotiating an Energy Deal under TTIP: Drivers and Impediments to U.S. Shale Exports to Europe

The problem of global security of energy supply is growing in importance. TTIP negotiations represent an opportunity to improve energy security in Europe and negotiate a legal framework for bilateral trade in energy, which could serve as a model for future negotiations at a multilateral level. This paper explores some of the thorniest legal, geopolitical, and economic issues that need to be taken up by TTIP negotiators for the promotion of a secure and sustainable trade in energy between the United States and European Union. It gives an account of the most recent developments in the TTIP negotiations on energy and examines the link between a possible legal framework for energy trade under TTIP and other energy-related regional and international fora. The paper critically assesses the negotiating positions of the European Union and the United States in light of their reciprocal energy profiles and needs. It offers an overview of the critical items most likely to be on top of the TTIP agenda on energy based on a comparative analysis of energy provisions in E.U. and U.S. legislation and in light of the both parties’ interests. Finally, it discusses the main driving forces and inhibiting factors capable of facilitating or rather impeding a successful conclusion of an energy trade deal between the United States and the European Union.
