Identification of the problem or opportunity that it proposes to address<\/strong><\/p>\n

The production of chestnut is strongly conditioned by the average and extreme weather conditions verified during its annual cycle. The diseases and pests that affect and decimate chestnut trees are also associated with specific environmental conditions. Thus, the economic potential and development strategy of the Castanha Row in Portugal face the difficulties resulting from climate variability and climate change (see technical annex). Climate projections for the future in Portugal suggest significant changes in mean values \u200b\u200b(temperature and monthly and annual precipitation), in variability and in the magnitude and frequency of extreme events (e.g. intense precipitation, drought, heat waves, etc.). This initiative arises in the context of the Fileira's growth strategy (increase in the production area) and aims to provide a set of products to support political decisions and support producer associations. Climate changes currently observed and projected for the future, such as the global increase in air temperature and changes in the precipitation regime, will have, among other effects, a strong impact on the vegetation cover, extremely dependent on atmospheric conditions.<\/p>\n

The chestnut tree presents weaknesses resulting from the low tolerance to the combination of water and thermal stresses that result in the loss of vigor and productivity as well as an abnormal increase in the mortality rate of trees. In fact, recent data from INE for the period between 2000 \u2013 2015 reveal that chestnut production:
\n(i) decreased from 33,000 to 24,000 ton, despite the increase in the cultivated area from 29,000 to 35,000 ha; and,
\n(ii) shows high interannual variability with extreme cases clearly associated with the occurrence of extreme climatic episodes during the growing season.<\/p>\n

Furthermore, it is necessary to take into account the biotic and abiotic threats, responsible for undesirable fluctuations in the fruit market (production and price), which constitute serious problems for the chestnut processing industry. Despite this situation, the sector shows strong growth dynamics reflected in a strategic plan, framed in the proposal of the European chestnut group, to counteract the decrease in chestnut production in Europe, in order to increase the production area to 50,000 ha until 2020. This initiative\/proposal arises in order to seize the opportunity of the sector's development strategy and, in the context of climate change.<\/p>\n

Aimed objectives<\/strong>
\nIn a context of strong growth dynamics in areas of new plantations, it is urgent to provide accurate information to potential investors about the culture model. It is intended to characterize the regions from the point of view of present and future climatic conditions as well as to provide a set of climatically influenced biotic and abiotic parameters that allow technicians and producers to make the best decisions resulting from climate change, namely, to successfully adapt, the existing chestnut groves to the new soil and climate conditions and the definition of new areas for cultivation, in order to maintain adequate levels of nut production.
\nClimCast's goals include:<\/p>\n

\u2013 Comparar comportamento do conjunto das variedades recomendadas para cada DOP em locais com condi\u00e7\u00f5es clim\u00e1ticas contrastantes;
\r\n\u2013 Monitorizar a evolu\u00e7\u00e3o dos solos onde ser\u00e3o feitas as planta\u00e7\u00f5es, dada a depend\u00eancia das suas caracter\u00edsticas f\u00edsico-qu\u00edmicas e biol\u00f3gicas com as condi\u00e7\u00f5es meteorol\u00f3gicas e clim\u00e1ticas, nomeadamente da temperatura e precipita\u00e7\u00e3o;
\r\n\u2013 Implementar o sistema de monitoriza\u00e7\u00e3o clim\u00e1tica ClimCast a partir de cada uma dessas unidades de demonstra\u00e7\u00e3o, que permitir\u00e1 recolher informa\u00e7\u00e3o detalhada em cada SD, melhorar o conhecimento da rela\u00e7\u00e3o entre as condi\u00e7\u00f5es meteorol\u00f3gicas e o castanheiro e que ser\u00e1 o embri\u00e3o de uma futura rede de avisos para o castanheiro;
\r\n\u2013 Identificar as vari\u00e1veis meteorol\u00f3gicas, \u00edndices de dete\u00e7\u00e3o remota e outros par\u00e2metros (e.g., \u00edndices de seca) com maior potencial preditivo da produtividade da castanha em Portugal;
\r\n\u2013 Caracterizar climaticamente as principais regi\u00f5es produtoras de castanha, nas condi\u00e7\u00f5es atuais e de clima futuro para permitir selecionar a melhor variedade para cada situa\u00e7\u00e3o edafoclimatica;
\r\n\u2013 Mapear as regi\u00f5es produtoras e potencialmente produtoras de castanha em fun\u00e7\u00e3o das suas caracter\u00edsticas clim\u00e1ticas e consequente aptid\u00e3o para a produ\u00e7\u00e3o de castanha, criando uma gradua\u00e7\u00e3o da situa\u00e7\u00e3o de risco da cultura;
\r\n\u2013 Desenvolver modelos clim\u00e1ticos de produtividade e carta de produ\u00e7\u00e3o potencial da castanha em Portugal;<\/p>\n

And, finally, to produce a manual of good chestnut cultivation practices, in the context of climate change, aimed at producers in this sector.<\/p>\n

Action plan summary<\/strong>
\nThe new challenges for the grove in the context of climate change. The economic potential and development strategy of the Castanha Row in Portugal faces several difficulties resulting from variability and climate change. The production of chestnut is strongly conditioned by the average and extreme weather conditions verified throughout its annual cycle. The diseases and pests that affect and decimate chestnut trees as well as the presence of rot and pests on the fruits are also associated with specific environmental conditions. Climate projections for the future in Portugal suggest significant changes in mean values \u200b\u200b(temperature and monthly and annual precipitation), in variability and in the magnitude and frequency of extreme events (e.g. intense precipitation, drought, heat waves, etc.). This initiative arises in the context of the Fileira's growth strategy (increase in the production area) and aims to provide a set of products to support political decisions and support producer associations.<\/p>\n

Status \/ Results<\/strong>
\nGO's actions focus on two main axes:
\n1) Installation of demonstration chests accompanied by the installation of weather stations
\n2) Climate modeling.<\/p>\n

Em rela\u00e7\u00e3o ao ponto 1, come\u00e7amos por salientar que a data de inicio do GO acabou por condicionar a instala\u00e7\u00e3o dos soutos. Na verdade a primeira reuni\u00e3o geral do GO foi a 13 de janeiro de 2018, data em que apesar do adiantado da \u00e9poca para preparar planta\u00e7\u00f5es se decidiu avan\u00e7ar. Veio mais tarde a verificar-se n\u00e3o ter sido a melhor op\u00e7\u00e3o porque as planta\u00e7\u00f5es foram feitas a partir de in\u00edcios de mar\u00e7o, tendo-se verificado bastante insucesso nos pegamentos conforme reportado nos relat\u00f3rios. Da\u00ed para c\u00e1, fizeram-se as replanta\u00e7\u00f5es e foram feitas as primeiras enxertias em 2019. Estamos ainda numa fase de reenxertias, embora se tenha j\u00e1 come\u00e7ado a retirar informa\u00e7\u00e3o dos soutos.
\r\nEm rela\u00e7\u00e3o ao ponto 2, os trabalhos de modela\u00e7\u00e3o est\u00e3o numa fase bastante avan\u00e7ada, havendo j\u00e1 modelos de previs\u00e3o de produ\u00e7\u00e3o, baseados em hist\u00f3rico de dados clim\u00e1ticos, com grau bastante grande de fiabilidade. Em rela\u00e7\u00e3o aos dados das esta\u00e7\u00f5es meteorol\u00f3gicas est\u00e3o a centralizados, estando articulado todo o processo.<\/p>\n<\/div>\n<\/div>","protected":false},"excerpt":{"rendered":"
