The Dutch Energy Markets in 2009: Target Scenario – Obstacles – Measures

Competition on the wholesale gas market is still in its early stages. Measures have already been put in place to eliminate some shortcomings, these are the new market model and the market-based balancing system. Both of these are the result of the Gas Letter from the Minister and the underlying TTF advice from the NMa. These measures facilitate a development towards more competition. But for a better functioning market the commitment of all market participants is required. Gasterra, the exclusive marketer of Groningen gas, has a key responsibility here. Energy suppliers should be able to obtain gas on the TTF in the required periods and quantities. Otherwise the development of the wholesale gas market will just be stalled further.Monitoring, electricity, gas, competition, infrastructure

Sphingolipids as emerging mediators in retina degeneration

The sphingolipids ceramide (Cer), sphingosine-1-phosphate (S1P), sphingosine (Sph), and ceramide-1-phosphate (C1P) are key signaling molecules that regulate major cellular functions. Their roles in the retina have gained increasing attention during the last decade since they emerge as mediators of proliferation, survival, migration, neovascularization, inflammation and death in retina cells. As exacerbation of these processes is central to retina degenerative diseases, they appear as crucial players in their progression. This review analyzes the functions of these sphingolipids in retina cell types and their possible pathological roles. Cer appears as a key arbitrator in diverse retinal pathologies; it promotes inflammation in endothelial and retina pigment epithelium (RPE) cells and its increase is a common feature in photoreceptor death in vitro and in animal models of retina degeneration; noteworthy, inhibiting Cer synthesis preserves photoreceptor viability and functionality. In turn, S1P acts as a double edge sword in the retina. It is essential for retina development, promoting the survival of photoreceptors and ganglion cells and regulating proliferation and differentiation of photoreceptor progenitors. However, S1P has also deleterious effects, stimulating migration of Müller glial cells, angiogenesis and fibrosis, contributing to the inflammatory scenario of proliferative retinopathies and age related macular degeneration (AMD). C1P, as S1P, promotes photoreceptor survival and differentiation. Collectively, the expanding role for these sphingolipids in the regulation of critical processes in retina cell types and in their dysregulation in retina degenerations makes them attractive targets for treating these diseases.Fil: Simon, Maria Victoria.

Potential Applications of Food-Scanners in Fruit and Vegetable Supply Chains and Possible Consequences for the German Market

Originally advertised as tools for end-consumers, food-scanners have recently gained publicity and show potential as instruments for quality assessment along the fruit and vegetable supply chain. The current study explores preferences and concerns of chain actors regarding the implementation of this technology through semi-structured interviews. Results indicate that food-scanners could facilitate quality control at different levels of the fresh produce supply chain by providing fast, non-destructive and objective measurements. Concerns about the application of food-scanners could be identified with respect to potential additional requirements of trading companies resulting in more pressure on producers. The use of food-scanners by end-consumers is discussed critically. To further a goal-oriented and user-directed development of this new technology, future research should be directed at its impacts on perception of fruit quality along the chain as well as end-consumers’ readiness to use these devices in everyday life

Assessment of agricultural information needs in African, Caribbean and Pacific (ACP) States for CTA’s Products and Services: Country Study: Mozambique

Executive summary Introduction CTA works primarily through intermediary organisations and partners (non-governmental organisations, farmers’ organisations, regional organisations) to promote agriculture and rural development and to deliver its various information products and capacity building services. By partnering with these organisations, CTA seeks to increase the number of ACP organisations capable of generating and managing information and developing their own information and communication management strategies. In the period 2003 – 2005, CTA undertook a series of needs assessment studies in 21 countries in the ACP Pacific and Caribbean. As a continuation of this process, CTA have now commissioned assessments of the agricultural information needs of 6 countries emerging from prolonged conflict situations in ACP Africa, including Mozambique, which forms the focus of this report. Objectives of the Study The objectives of this study are to develop a strategy for CTA’s approach to post-conflict countries, to improve the effectiveness of CTA’s support for post-conflict countries and to compile baseline data on the status of ICM and ICTs in agriculture and rural development in Mozambique. Methodology The country profile was produced through a desk study. This study relied heavily on information available on the internet and additional information was obtained from various institutions in Mozambique, internationally and from key informants. Through the desk study we were able to identify a list of nine key institutions. This list was discussed with CTA and informants in Mozambique and face to face interviews were requested with each institution. Of these, seven of the institutions agreed, whilst one indicated that it would be closing its operations within a year and was therefore removed from the list. Expected results This study will provide: 1) an inventory of the status of agricultural information services, institutions and other actors and their needs as their relate to physical infrastructure, information availability and access and human capacity development; 2) an assessment of the current and / or planned interventions of the government and bi- or multilateral agencies in the field of information for agriculture and rural development; 3) an overview of the needs of potential partners for CTA activities and services in terms of building capacity for information and communication management; 4) a short-list of potential partners / beneficiaries for CTA activities and services; 5) baseline data to facilitate subsequent monitoring activities. The study will also provide a framework for CTA to develop a framework for action and fashion a strategy aimed at institutions in countries emerging from conflict situations and provide input into its 2006 – 2010 strategic plan. Findings Following the signing of a peace agreement in 1992 to end 16 years of conflict, Mozambique has achieved impressive economic growth and lowered its prevalence of poverty. Sustained by strong foreign investment, real GDP in Mozambique has been growing at rates in excess of 7 percent for the last 4 consecutive years, and per capita income in US dollars has increased by nearly 50 percent between 2001 and 2004. Mozambique’s economic growth, however, implies an important transformation in the composition of its GDP, although services remain the dominant sector. The share of industry in total GDP increased to 27 percent in 2004 from about 16 percent in 1996, whereas the share of agriculture decreased to 23 percent from about 30 percent in the same period. The agricultural sector, however, still supports 80 percent of the economically active population, and agriculture still provides major export earnings from commodities such as prawns and fish, cotton, sugar, timber and cashew nuts. The forestry sector also has an important role in the country, contributing 4 percent of gross domestic product and supplying about 80 percent of the energy used. There is no unified policy or strategy in Mozambique with regard to the management of agricultural information and broad dissemination networks are not well developed. Institutions that fall outside of the state or donor worlds often find it difficult to get hold of information. Information exchange between institutions tends to be informal rather than structured. Agricultural research generally is restricted by the insufficient number of scientists who can formulate and carry out studies relevant to Mozambican needs. Budgets for information management tend to be a low priority. In-house capacity for maintaining and troubleshooting computer networks is a constraint; reliance is made upon private companies specialised in IT. Retention of staff at the centre with IT skills, in the face of competition from the private sector, was cited as a problem by all of the state agencies. Building the capacities of in-house staff was therefore felt to be important. Existing websites, maintained by some of the key institutions vary in their effectiveness as publishing outlets and often tend to be reflections of the institution, its structure and its work programme, rather than being designed specifically to disseminate information, reports, studies, etc. that are produced, or to act as advocacy tools. Use of radio as a means of disseminating information in vernacular languages is still rather limited. Problems in this respect are the costs of translation and payments for the transmissions. Training in how to pass information on to low literacy groups was also indicated by several agencies. This included training in more effective writing skills and training in how to compile radio programmes and audio visual materials. There is a general lack of metadata; documentation on who is doing what and types of available information is generally poor. This has a double negative effect. On one hand, potential data and information users have difficulties finding or getting access to relevant information and on the other hand, information suppliers do not know what they have, which prevents better organisation of information for dissemination. Conclusions Most of the institutions which we interviewed have fairly well-developed links to relevant sources of information; data on the functioning of markets, prices and production levels in the agriculture and fisheries sectors has vastly improved in recent years. Some of these agencies need information on regional and international markets and production levels. Technical data is still harder to source, particularly in Portuguese. There are information needs regarding developments in thinking on food security, forms and means of supporting organisations at community level, participatory approaches to resource management, information on low cost technologies for increasing production and conserving produce, on gender, on HIV/AIDS prevention and mitigation strategies and on general rural development issues. Respondents requested capacity building in information management to increase the effectiveness of their organisations. Government services and NGO staff indicated the importance of training in the analysis of socio-economic data. Training in the use of the internet to obtain information and in the targeting of information by library and documentation services was also a broad need. The design and development of web sites was indicated by many respondents, but it is felt that there is a particular need for support in how to conceptualise these as sources of information rather than just ‘publicity’. Training in effective communication to low literacy target audiences, in the development of extension materials and the use of radio and audio-visual materials is also important. Recommendations We recommend that CTA provide support to the development of a national IMC strategy for agricultural information that takes full advantage of the opportunities offered by the new GovNet infrastructure. The ICM strategy should ensure that information is easily available to all stakeholders in rural development. Furthermore, the ICM strategy should prevent a gap from evolving between organisations connected to GovNet and those that are not. Finally, the ICM should provide for communication channels from the rural poor to research organisations and policy makers, to ensure that research and policies are guided by the needs of poor rural households. We recommend that CTA attempts to increase the amount of information disseminated in Portuguese language, particularly in regard to food security, forms and means of supporting organisations at community level, participatory approaches to resource management, information on low cost technologies for increasing production and conserving produce, on gender, on HIV/AIDS prevention and mitigation strategies and on general rural development issues. We recommend that CTA support short term research activities targeted at Mozambican-specific issues in relation to agricultural production and the conservation of produce. Links should be set up to inform IIAM and DNER about the information needs of poor farmers, women and PLWHA. These links can be set up through members organisations such as ORAM and UNAC, through Farmer Field Schools and through NGOs to which DNER has outsourced extension activities. We recommend that CTA investigate ways of supporting exchange of experience between organisations involved in training through associations and support to the development of training packages for associations. These should be provided to increase the effectiveness and efficiency of extension efforts in the field. In the long term, the required technical information can be provided to associations through newly developed training packages.The objectives of this study are to develop a strategy for CTA’s approach to post-conflict countries, to improve the effectiveness of CTA’s support for post-conflict countries and to compile baseline data on the status of ICM and ICTs in agriculture.

Assessment of agricultural information needs in African, Caribbean and Pacific (ACP) States for CTA’s Products and Services: Country Study: Angola

Executive summary Introduction CTA works primarily through intermediary organisations and partners (non-governmental organisations, farmers’ organisations, regional organisations) to promote agriculture and rural development and to deliver its various information products and capacity building services. By partnering with these organisations, CTA seeks to increase the number of ACP organisations capable of generating and managing information and developing their own information and communication management strategies. This study is one of six country assessment studies of needs for agricultural information needs in countries emerging from prolonged conflict situations in Africa. Objectives The objectives of this study are to develop a strategy for CTA’s approach to post-conflict countries, to improve the effectiveness of CTA’s support for post-conflict countries and to compile baseline data on the status of ICM and ICTs in agriculture and rural development in Angola. Methodology The country profile was produced through a desktop study that relied heavily on information available on the Internet. Additional information was obtained from informants through e-mail contacts. Using the desktop study we compiled a list of key institutions to interview. This list was discussed via e-mail with CTA and informants in Angola. Informants of nine key institutions were then interviewed face-to-face. Expected results This study will provide: 1) an inventory of the status of agricultural information services, institutions and other actors and their needs as their relate to physical infrastructure, information availability and access and human capacity development; 2) an assessment of the current and / or planned interventions of the government and bi- or multilateral agencies in the field of information for agriculture and rural development; 3) an overview of the needs of potential partners for CTA activities and services in terms of building capacity for information and communication management; 4) a short-list of potential partners / beneficiaries for CTA activities and services; 5) baseline data to facilitate subsequent monitoring activities. The study will also provide a framework for CTA to develop a framework for action and fashion a strategy aimed at institutions in countries emerging from conflict situations and provide input into its 2006 – 2010 strategic plan. Findings During the civil war between UNITA and the Angolan Government that lasted until 2002, the infrastructure in Angola, especially in rural areas, was almost completely destroyed. Since 2002, up to 4.5 million displaced people were resettled in their area of origin or preference and received emergency support. About 2.2 million households (75% of the population) are engaged in subsistence agriculture. Agricultural production is still low but growing rapidly. Since 2002 the area under cultivation has increased with 50 % to 3.2 million hectare but that represents still only 5% of all arable land and Angola still imports about half of its cereal requirements. The main export crops are coffee and palm oil. Livestock numbers are also increasing rapidly since 2002. The production is concentrated in the southern provinces. Access to water is the main constraint for livestock holders in these areas. Fisheries are an important sector, providing direct employment to 35,000 people. Firewood and charcoal are an important source of income for up to 18% of the rural households and the only source of energy to almost all rural households. Timber production is concentrated in Cabinda province. Agriculture, forestry and fisheries contribute 8% to the GNP. Because of the weak infrastructure and the focus on emergency projects, which spent only the minimum on obtaining information and ICM, there is limited information available about the situation in rural areas. The information that is available is fragmented and scattered in many project evaluation reports. To cope with this situation, an informal network of information exchange has developed between NGOs, GoA and bi- and multilateral agencies in Angola over the last four years. The language barrier and outdated libraries are the main obstacles encountered by organisations searching for technical information on agriculture. Limited access to mass media and weak infrastructure are the main obstacles encountered in extension activities. There is currently no national strategy on information management and none of the organisations interviewed had an organisational strategy on information management. Organisations working in the area of agriculture and rural development are now changing to development activities and this change is accompanied by some important changes in information demands. Firstly, there is an increased need for active participation in the planning and implementation of activities by the target group. Secondly, new actors are coming in, while present ones are leaving. Thirdly, it is expected that rural households in Angola will increase production above subsistence level in the near future and will be looking for opportunities to market excess production or divert resources to cash crops. Fourthly, the government is relaxing media controls, allowing freer communication between all stakeholders and a potential increase in the use of media by NGOs. Conclusions Most respondents need information on the actual situation on the ground. Existing information produced between 2002 and 2006 is scattered over many organisations and reports. This information must be consolidated in a data-base before the main implementers leave Angola. Respondents also need information about developments in thinking on food security, rural livelihoods, participatory approaches to resource management and rural development preferably in the form of reference books. Furthermore, information is needed on micro credit and support to associations. This information should be in the form of manuals and exchange visits to successful projects, preferably in Portuguese speaking and/or African countries. Finally, technical information on food crops and fisheries is needed. Respondents need capacity building in information management to increase the effectiveness of the organisation. Especially government officials requested training in the analysis of socio-economic data. Training in the design of questionnaires and in training the interviewers is also necessary. Furthermore, respondents wanted training in the use of the Internet to obtain information and in the design and development of websites, in effective writing and the development of extension materials, in the use of participatory methods and in demand driven extension. Finally, some respondents wanted training in the use of mass media, especially radio and in the production and use of audio-visual training material. Recommendations We recommend that CTA support IDA with the development of a national IMC strategy for agricultural information that will encourage a pro-poor and gender sensitive development strategy. CTA should also supports IDA, FONGA and ADRA with the establishment of an institutional ICM. This would include building a data-base with all information produced to date. Additionally CTA should support a policy for the use of mass media, especially community radio in extension programmes. Simultaneously, the most needed information will have to be made available at central level for ongoing work. Small libraries can be set up for this at IDA and FONGA. Second, a programme of capacity building is needed to enable all actors to implement the policies formulated in the first phase. This programme should be accompanied by a limited provision of resources (Internet access, increased libraries). Trained personnel musts have the resources to use their new skills to implement activities. Successful approaches used at central level can be replicated at provincial level during this stage. Care must be taken that the information system remains pro-poor and gender sensitive. Possibly, specific actions to help prevent the spread of HIV and mitigate its effects should be taken during this phase. Finally, in the long term, specific technical information will need to be supplied for specific target groups such as fish breeders and farmers specialising in niche markets.The objectives of this study are to develop a strategy for CTA’s approach to post-conflict countries, to improve the effectiveness of CTA’s support for post-conflict countries and to compile baseline data on the status of ICM and ICTs in agriculture.

Metagenetic analysis of patterns of distribution and diversity of marine meiobenthic eukaryotes

AimMeiofaunal communities that inhabit the marine benthos offer unique opportunities to simultaneously study the macroecology of numerous phyla that exhibit different life-history strategies. Here, we ask: (1) if the macroecology of meiobenthic communities is explained mainly by dispersal constraints or by environmental conditions; and (2) if levels of meiofaunal diversity surpass existing estimates based on morphological taxonomy. LocationUK and mainland European coast. MethodsNext-generation sequencing techniques (NGS; Roche 454 FLX platform) using 18S nuclear small subunit ribosomal DNA (rDNA) gene. Pyrosequences were analysed using AmpliconNoise followed by chimera removal using Perseus. ResultsRarefaction curves revealed that sampling saturation was only reached at 15% of sites, highlighting that the bulk of meiofaunal diversity is yet to be discovered. Overall, 1353 OTUs were recovered and assigned to 23 different phyla. The majority of sampled sites had c. 60-70 unique operational taxonomic units (OTUs) per site, indicating high levels of beta diversity. The environmental parameters that best explained community structure were seawater temperature, geographical distance and sediment size, but most of the variability (R-2=70%-80%) remains unexplained. Main conclusionsHigh percentages of endemic OTUs suggest that meiobenthic community composition is partly niche-driven, as observed in larger organisms, but also shares macroecological features of microorganisms by showing high levels of cosmopolitanism (albeit on a much smaller scale). Meiobenthic communities exhibited patterns of isolation by distance as well as associations between niche, latitude and temperature, indicating that meiobenthic communities result from a combination of niche assembly and dispersal processes. Conversely, isolation-by-distance patterns were not identified in the featured protists, suggesting that animals and protists adhere to radically different macroecological processes, linked to life-history strategies.Natural Environment Research Council (NERC) [NE/E001505/1, NE/F001266/1, MGF-167]; Portuguese Foundation for Science and Technology (FCT) [SFRH/BD/27413/2006, SFRH/BPD/80447/2014]; EPSRC [EP/H003851/1]; BBSRC CASE studentship; Unilever; Biotechnology and Biological Sciences Research Council [987347]; Engineering and Physical Sciences Research Council [EP/H003851/1]; Natural Environment Research Council [NE/F001290/1, NE/F001266/1, NE/E001505/1, NBAF010002]info:eu-repo/semantics/publishedVersio
