Having a reliable method to get the number of flowers in a bunch is critical to analyze the effects of different stresses (biotic or abiotic) on blooming and fruit set. Here, it is presented a simple, yet, accurate method to obtain the number of flowers per bunch using a free software image analyzer. The bunches, are randomly selected at the experimental site and take it to the lab. In the lab, flowers are detached from the calyptra and placed in a black matt plastic sheet. Flowers are gently spread on the plastic sheet to avoid overlapping. Next, a picture is taken using a camera fixed to a holder. The plastic sheet must have a reference length for the further analysis with the software. The image is processed using the ImageJ software. Once processed, the number and perimeter of each flower are obtained. The bias analysis gives an overestimate of nearly 10 flowers, which, given the number of flowers per bunch, (for Tempranillo it could be more than 800) it can be considered an acceptable error. However, the bias can be diminished if a specific calibration is set. The images do not need to be clean. Non-desired elements can be removed from the analysis by applying a filtering method. The present methodology provides a simple, fast and precise technique to obtain the number of flowers in a bunch for research purposes.*

Check out the latest article from My Climate Services presenting our project and how it aims to make the European wine industries resilient to climate change: VISCA: Protecting 20 Billion Euros from Climate Change
Organised by the Regional Chamber of Agriculture in Provence-Alpes-Côte d'Azur and a multi-sector committee on 16 - 18 October 2018 in Avignon, France, the MED'Agri trade faire was entirely dedicated to the agricultural production and the agri-technology.
A lot of showcase of innovative techniques were presented during the event. MED'Agri is aimed at professionals of all the agricultural production sectors and farmers and in particular those represented in the South of the France: market gardening, arboriculture, viticulture, olive growing, breeding and also horticulture, beekeeping, truffle, aromatic and fragrant plants, etc. VISCA project was presented at a dedicated stand by SEMIDE as well as the projects involved at the Common Dissemination Booster: WEAM4i and OpIRIS.

The 2nd edition of the Climateurope Festival was organised in Belgrade from 17th to 19th October 2018 in order to support the exchange of knowledge and cultivate efforts for climate change adaptation and mitigation informed by science. The event brought researchers, suppliers, and funders with an emphasis on participants from Central and Eastern Europe. Varied programme was offered including lectures, discussions and networking to explore the state-of-the-art of climate information, and its uses and value in decision-making.
VISCA project was presented during the Climateurope Festival 2018 in 2 different sessions, one on the “Future of wine: Round table / Impulse talks” on October 18th and the other on “Climate information at your services I. Agriculture: Storytelling session & Round table” on October 19th.
On 2nd-3rd May 2018, the EU AgriResearch Conference took place in Brussels targeting scientists, farmers, rural communities, industry, advisors, policy-makers, citizens and NGO representatives who wish to learn about EU agriculture and rural R&I activities and achievements and have their say on how to shape the future of agriculture R&I after 2020. The conference was also a great occasion to network with around 500 peers.
During the conference, different topics about the H2020 program and priorities in the agriculture sector were presented including presentations about EU-funded projects. The implementation of the strategic approach to EU agricultural R&I and present its first achievements on knowledge produced, linkages established between EU policies or new avenues opened in terms of implementation approaches were discussed.
Few farmers also participated in the event and some discussions on how to better involve them took place concluding that the language and the timing of harvest season should always be taken into consideration.
VISCA project was disseminated during the event by SEMIDE. Exchanges and contacts were gathered in order to make collaborations in the replicability and synergies foreseen in the project.
Have a Pint of Science!
Isadora and Dragana from Barcelona Supercomputing Centre (BSC) will talk about new trends in climate change adaptation and innovation. The Pint of Science festival aims to deliver interesting and relevant talks on the latest science and research in an accessible format to the public, mainly across bars and pubs.
Isadora will talk about how and why forecasting the weather is important. The current trend of wine production in the Pyrenees, as a consequence of global warming, is only one of the examples Isa will use to demonstrate how to adapt to climate change and the full potential of computer modelling in tackling the challenges of tomorrow’s life on Earth.
During the 1st Stakeholders Workshop of VISCA project, a questionnaire was created in order to establish an overview of the current adaptation strategies adopted by the different agricultural sectors against climatic changes as well as to gather the users’ requirements and expectations from VISCA tool. The questionnaire was answered by 11 different organisations representing agricultural and climate services communities from the private organisations as well as research centres and professional public institutions. The geographical area of influence of the participating organisations was mostly in Europe, but it also included other regions such as South America, North America, Africa, the Mediterranean basin and Vietnam which gave a global view to VISCA questionnaire.
