Der Anstieg des Meeresspiegels als Thema für den VN-Sicherheitsrat: Die völkerrechtliche Dimension des Problems muss stärker in den Fokus rücken

Deutschland wird im Juli 2020 den Vorsitz im Sicherheitsrat der Vereinten Nationen übernehmen und den Blick der Staatengemeinschaft erneut auf die sicherheits­relevanten Folgen des Klimawandels lenken. Besorgniserregend ist besonders, dass der Meeresspiegel mit zunehmender Geschwindigkeit ansteigt. Dies birgt die Gefahr einer dauerhaften Überflutung niedrig gelegener Küstengebiete und kleinerer Inseln. Dar­aus ergeben sich auch schwierige völkerrechtliche Fragen, auf die das geltende Recht nur zum Teil Antworten liefert. Daher müssen einzelne Regelungsmaterien wie etwa das Seerecht oder der Individualschutz weiterentwickelt werden. Denkbar ist zum einen, dass etablierte Normen und Prinzipien im Lichte neuer Herausforderungen progressiv ausgelegt werden. Zum anderen ließen sich Lücken durch zusätzliche ver­tragliche Regelungen schließen. Damit politische Spielräume für eine Fortentwicklung des völkerrechtlichen Instrumentariums entstehen können, ist ein breiterer Dia­log unter den Staaten nötig. Der Sicherheitsrat könnte maßgebliche Anstöße liefern, um einen solchen Austausch in Gang zu bringen

A human RNA polymerase II subunit is encoded by a recently generated multigene family

BACKGROUND: The sequences encoding the yeast RNA polymerase II (RPB) subunits are single copy genes. RESULTS: While those characterized so far for the human (h) RPB are also unique, we show that hRPB subunit 11 (hRPB11) is encoded by a multigene family, mapping on chromosome 7 at loci p12, q11.23 and q22. We focused on two members of this family, hRPB11a and hRPB11b: the first encodes subunit hRPB11a, which represents the major RPB11 component of the mammalian RPB complex ; the second generates polypeptides hRPB11bα and hRPB11bβ through differential splicing of its transcript and shares homologies with components of the hPMS2L multigene family related to genes involved in mismatch-repair functions (MMR). Both hRPB11a and b genes are transcribed in all human tissues tested. Using an inter-species complementation assay, we show that only hRPB11bα is functional in yeast. In marked contrast, we found that the unique murine homolog of RPB11 gene maps on chromosome 5 (band G), and encodes a single polypeptide which is identical to subunit hRPB11a. CONCLUSIONS: The type hRPB11b gene appears to result from recent genomic recombination events in the evolution of primates, involving sequence elements related to the MMR apparatus

Creating Conditions for Harnessing the Potential of Transitions to Agroecology in Europe and Requirements for Policy

Food systems require reorientation to take greater account of interactions with the environment, economy, health and society. Transitions to agroecological farming practices and systems can connect policy areas and realise environmental, economic and social aims. These transitions provide a lens for reviewing policy, practice and behaviours of actors in farming systems and value chains, identification of barriers to uptake, and policy areas to which they contribute or where there are gaps. Developing social and human capital, and governance structures that enable transitions to agroecology are key to their prospects of success. Education and life-long learning are key to developing the knowledge and skills of younger generations of land managers and other actors in value chains, throughout their careers. The outcome sought is for a shared understanding of the benefits of agroecological practices and systems, creating opportunities to rebalance policies towards delivering climate neutrality, reversing biodiversity loss, and enhancing rights of citizens. To realise those opportunities policies and strategies should be coherent across territorial and systems levels, and tailored to place, system, people, and stages of transitions. Overall, they should be designed to ensure all citizens are beneficiaries of transitions to agroecological farming systems, over the long term, and that no-one or place is disadvantaged by the processes of change or the outcome intended.</p

Socio-economic impact of ecological agriculture at the territorial level

This deliverable investigates the socio-economic effects of ecological approaches to farming through implementing two participatory approaches, namely Delphi exercise and Q-method, at the level of a case study area (CSA). The focus is on how people and other productive assets are employed and remunerated by ecological approaches to agriculture, particularly those aspects that can influence employment, and drive the prosperity and vitality of local communities and some rural businesses. It is based on the collaborative research on Task 4.2 ‘Socio-economic impact of ecological agriculture at the territorial level’ of the LIFT project between UNIKENT (United Kingdom-UK) (Task Leader), BOKU (Austria), INRAE (France), VetAgro Sup (France), DEMETER (Greece), MTA KRTK (Hungary), UNIBO (Italy), IRWiR PAN (Poland), IAE-AR (Romania), SLU (Sweden), SRUC (UK). Beginning with the Delphi exercise, this deliverable presents qualitative information extracted from stakeholders in the following four steps. First, the researchers build a presentation of differences between ecological and conventional farming approaches in each CSA. Second, stakeholders elaborate on how they understand ecological farming approaches to exist in each CSA. Third, stakeholders develop a scenario of adoption of ecological approaches to farming depending on two factors: pattern (ecological farms forming clusters or randomly spread within the territory) and rate of adoption 10 years in the future. After establishing this scenario across two rounds, the stakeholders explore the socio-economic effects of their adoption scenario. The Q-methodology then presents a Q-set of statements that the Delphi has developed and, through factor analysis,studies the key stakeholder perspectives of the socio-economic effects of the perceived adoption of ecological practices in 10 years in the future. Four key results can be derived from the Delphi exercise and the Q-methodology. First, a higher adoption of ecological farming approaches, especially so at a 50% adoption rate, is mostly thought by stakeholders in the Delphi Exercise to lead to an increase in skill level and quality of life in on-farm employment. This is as a result of an increased diversity of farming enterprises on farms using ecological farming approaches, the interest generated from this, the knowledge of natural processes and biology required, engagement with nature and change in machinery that is coming into the industry. Strongly related to this need for skills is a predicted increase in the number of advisers and civil servants to deal with more complicated farms and incentives as well as monitoring of ecological effects on farm. An increase in required skill level is repeated across all Q-studies. Second, especially where farms are clustered together, Delphi Exercise respondents predict an increase in the trade of inputs such as manure and compost replacing synthetic fertiliser, as well as more sharing of capital and labour. Q-methodology highlights that these clusters may support a stronger social movement, more consumers buying local food and increase collaboration between farmers. Supply chains are expected to become shorter as farmers sell more directly and there are fewer intermediaries upstream of the farming sector. As farmers collaborate more with each other on environmental objectives, trading inputs and sharing best practices, farmer relationships should improve in rural communities. Third, Delphi exercise finds that contracting, machinery purchasers, and machinery traders and dealers could increase, decrease or display no change – the anticipated effects are mixed. Stakeholders are in no doubt that machinery use will change and therefore new skills will need to be learnt, but the wider effect on machinery purchase is uncertain. However, stakeholders conclude that a greater specialisation in machinery will occur leading to changes in farm management as well as the suppliers of this machinery. Q-methodology highlights that ecological practices will not mean the end of machinery and a lot more labour – often machinery will be useful in weeding and reducing physical labour as technology has significantly improved and skills are improving too in order to use these technologies. Fourth, Delphi respondents argued that although rural populations might be little affected by ecological farming, a shift in people moving from urban to rural settlements, and thereby a higher rural population density, seeking a more attractive rural environment, might contribute to higher local consumer demand. The Q-methodology highlights that where there is high adoption, rural areas are expected to become more attractive, as landscapes will have a much greater variety of crops instead of fields of monocrops. This variety of crops may include agroforestry (farmers interested in ecological approaches to farming may also be interested in agroforestry as a way of boosting their yields and protecting crops and livestock from the elements) as well as intercropping
