<p>Nowadays, the importance of coastal areas is greater than ever, with approximately 10% of the global population living in these areas. These zones are an intermediate space between sea and land and are exposed to a variety of natural (e.g. ground deformation, coastal erosion, flooding, tornados, sea level rise, etc.) and anthropogenic (e.g. excessive urbanisation) hazards. Therefore, their conservation and proper sustainable management is deemed crucial both for economic and environmental purposes. The main goal of the Greece-China bilateral research project “EPIPELAGIC: ExPert Integrated suPport systEm for coastaL mixed urbAn – industrial – critical infrastructure monitorinG usIng Combined technologies” is the design and deployment of an integrated Decision Support System (DSS) for hazard mitigation and resilience. The system exploits near-real time data from both satellite and in-situ sources to efficiently identify and produce alerts for important risks (e.g. coastal flooding, soil erosion, degradation, subsidence), as well as to monitor other important changes (e.g. urbanization, coastline). To this end, a robust methodology has been defined by fusing satellite data (Optical/multispectral, SAR, High Resolution imagery, DEMs etc.) and in situ real-time measurements (tide gauges, GPS/GNSS etc.). For the satellite data pre-processing chain, image composite/mosaic generation techniques will be implemented via Google Earth Engine (GEE) platform in order to access Sentinel 1, Sentinel 2, Landsat 5 and Landsat 8 imagery for the studied time period (1991-2021). These optical and SAR composites will be stored into the main database of the EPIPELAGIC server, after all necessary harmonization and correction techniques, along with other products that are not yet available in GEE (e.g. ERS or Sentinel-1 SLC products) and will have to be locally processed. A Machine Learning (ML) module, using data from this main database will be trained to extract additional high-level information (e.g. coastlines, surface water, urban areas, etc.). Both conventional (e.g. Otsu thresholding, Random Forest, Simple Non-Iterative Clustering (SNIC) algorithm, etc.) and deep learning approaches (e.g. U-NET convolutional networks) will be deployed to address problems such as surface water detection and land cover/use classification. Additionally, in-situ or auxiliary/cadastral datasets will be used as ground truth data. Finally, a Decision Support System (DSS), will be developed to periodically monitor the evolution of these measurements, detect significant changes that may indicate impending risks and hazards, and issue alarms along with suggestions for appropriate actions to mitigate the detected risks. Through the project, the extensive use of Explainable Artificial Intelligence (xAI) techniques will also be investigated in order to provide “explainable recommendations” that will significantly facilitate the users to choose the optimal mitigation approach. The proposed integrated monitoring solutions is currently under development and will be applied in two Areas of Interest, namely Thermaic Gulf in Thessaloniki, Greece, and the Yellow River Delta in China. They are expected to provide valuable knowledge, methodologies and modern techniques for exploring the relevant physical mechanisms and offer an innovative decision support tool. Additionally, all project related research activities will provide ongoing support to the local culture, society, economy and environment in both involved countries, Greece and China.</p>

The International Coconut Genetic Resources Network (COGENT) is a global research network organized by the International Plant Genetic Resources Institute (IPGRI) in 1992 with support from member countries, the Consultative Group on International Agricultural Research (CGIAR), partner institutions, donor agencies, and by regional and international development organizations.                           In the last 12 years, COGENT has been fully operational with 38 member coconut producing countries in five regions (South Asia; Southeast and East Asia; South Pacific; Africa and the Indian Ocean; and Latin America and the Caribbean). It has successfully developed and disseminated to coconut breeders and curators worldwide the International Coconut Genetic Resources Database (CGRD). The CGRD contains characterization data and some pictures of 1,416 accessions which are conserved by national programmes in 28 sites in 23 countries. To further secure conserved germplasm, a COGENT multi-site International Coconut Genebank has been established to conserve 200 important accessions in each region. Coconut varieties with multi-purpose uses are being identified, documented and promoted. The performance of promising 38 high-yielding hybrids are being evaluated in a multilocation  trial involving four African and three Latin America/Caribbean countries to identify suitable varieties and hybrids for resource-poor farmers. Farmers’ varietal preferences in 15 countries are being evaluated. Diversity-linked income-generating activities are being used as a strategy to promote in situ and on-farm conservation and germplasm utilization have been initiated in 15 countries. Protocols for in vitro embryo culture, cryopreservation, morphometric and molecular marker-based methods for locating and characterizing diversity; pest risk assessment and germplasm health management are being developed, tested and upgraded. Strategies and techniques for farmer participatory research, collecting, characterization and ex situ and in situ conservation are being refined.   To strengthen the coconut research capability of COGENT member countries, the COGENT Secretariat and IPGRI have organized 39 country need assessment missions  and conducted 41 workshops and meetings involving 994 coconut researchers to share information and technologies, discuss issues and common problems and opportunities and how to address them; conducted 40 training courses involving 765 participants from 41 countries; supported 274  research and training/capacity building activities  in 30 countries; and led the establishment of the Global Coconut Research for Development Programme (PROCORD). IPGRI and COGENT's current priority involves the further promotion of more effective conservation and use of coconut genetic resources, both regionally and globally.

Abstract Central Kalimantan Province with total area of 15.380.000 ha or about 7.93 % of Indonesian areas consists of coastal regions and forest areas has potential biodiversity such as Orchidaceae. This region has various type of lands involving peat lands, swamplands with acid sulphate soils and up lands. The existence of orchid in Central Kalimantan’s forest can be found scattered in forest areas with high diversity life, form and uses. The methodology used include exploration and collection and they were conducted at six districts, i.e. East Barito, South Barito, North Barito, East Kotawaringin and Murung Raya, starting from March 2016 until December 2018. The objective of this study was as follows: (1). The exploration process, (2). The ex-situ and in-situ conservation, (3). The characterization process, (4). The documentation process. The results of these activities shown that there are several ex situ collection of 8 accessions of medicinal plants that can be used as a source of material for genetic improvement. The orchid plant’s conservation can be conducted through in-situ and or ex-situ. In-situ conservation can be conducted through managing forest areas as the natural habitat of the material for genetic improvement, while for ex-situ conservation, it can be managed outside of the native habitats. Appropriate utilization and research activities are important in conservation of the material for genetic improvement in Central Kalimantan

Conservation of native animal genetic resource is vital to maintain genetic diversity sustainably and to cope with the future challenging climate change. Thus, the aim of this paper was to review the experience of sheep conservation practice in Turkey and future prospects in Ethiopia. In turkey, fifteen sheep types are extinct and other native sheep population decreased by 47% due to an unplanned crossbreeding program. For these reasons, sheep genetic resource ex-situ in vivo conservation project started in 1995 with three sheep breeds. The animal breeding law regarding registration of new breed and conservation of animal genetic resources was enacted in 2001 in Turkey. In-situ conservation subsidies of sheep breeds near to extinction have been continued since 2005. Following these events, in vitro conservation of germplasm of 13 sheep breeds have been initiated in 2007 and two gene banks have been established and thereby sperm, embryo, cell, and DNA of from each sheep breed conserved in the gene bank. Although they were successful in both in-situ and ex-situ conservations with some limitations, in-situ conserved sheep breeds had better productivity than ex-situ in vivo conserved sheep in Turkey. In the case of Ethiopia, in-situ conservation will be compatible with the existing infrastructure. Through balancing the genetic gain and inbreeding level, it is possible to integrate the existing community-based genetic improvement programs (with in breed selection) with sustainable in-situ conservation of native sheep genetic resources in Ethiopia.

<p>Colombia es reconocida en el mundo por su megadiversidad en fauna, flora y microorganismos, atribuida a su gran complejidad ecosistémica y a procesos evolutivos de los Andes, la Orinoquia, Amazonia y de sus costas Pacífica y Caribe, en los que se encuentran páramos, selvas tropicales, humedales, llanuras y desiertos, entre otros. Con una superficie continental de alrededor del 0,77% del área terrestre del mundo, alberga aproximadamente el 10% de las especies vegetales y animales conocidas. Estos recursos genéticos tienen un valor estratégico importante para el país, y sus inventarios son una herramienta fundamental para el análisis del estado actual y potencial de ellos y para la toma de decisiones sobre medidas de conservación y renovación. En este ámbito, el Gobierno colombiano facilitó la conformación del Sistema de Bancos de Germoplasma de la Nación para la Alimentación y la Agricultura, el cual figura en cabeza del ICA y es manejado por Corpoica por medio de un convenio de Cooperación Técnica y Científica, suscrito con el ICA. Del total de accesiones vegetales que posee Colombia, mantenidas en condiciones ex situ, el 70% se maneja en Corpoica. El 30% restante corresponde a bancos activos. En general, en Colombia existen bancos de germoplasma donde se conservan las especies en la modalidad ex situ, lo que complementa procesos de mantenimiento in situ, que incluyen materiales en fincas de los productores.</p><p><strong><br /></strong></p><p><strong>State of Research of Plant Genetic Resources in Colombia: Germplasm Banks System</strong></p><p>Colombia is recognized worldwide for its megadiversity, which includes fauna, flora and microorganisms. The above is attributed to its highly ecosystemic complexity, derived from evolutionary processes in the Andes, the Orinoco, the Amazon and its Pacific and Caribbean coasts; regions where are located highlands, tropical jungles, wetlands, plains and deserts, among others. With about 0.77%, of the world’s land area, the country holds approximately 10% of the plant and animal species known around the world. These genetic resources hold an important strategic value for the country, and their inventories are a fundamental tool for the analysis of their current option and use values, as well as, for taking actions related to their conservation, renewal and utilization. In this context, the Colombian government promoted the establishment of a National Germplasm Bank System for Food and Agriculture, which comprises vegetal, animal and microorganism species, The System is administrated by ICA and managed by Corpoica, through a Technical and Scientific Cooperation Agreement subscribed by the last two entities. From all the plant species accessions, held under ex situ conditions at Colombia, 70% of those are included in the above System. The remaining 30% correspond, mainly to species, held under the criteria of active banks. From the above and, in relation to plant genetic resources, Colombia has an ex situ National Germplasm Bank System, for Food and Agriculture, which complements in situ conservation processes done in farm by local producers.</p>

<p>El crecimiento poblacional y los cambios en el entorno requieren de la disponibilidad de diversidad genética para el desarrollo de sistemas de producción sostenibles, eficientes y competitivos. Esto implica colectar, conservar y conocer los atributos de las poblaciones en mantenimiento de especies de valor actual y taxones relacionados, al igual que entidades biológicas con potencial de desarrollo, lo cual cobra importancia dada la creciente erosión genética. Esto plantea la necesidad de estrategias complementarias de conservación ex situ e in situ, dando prioridad a la variabilidad genética a ser incluida en el proceso, debido a los costos de mantenimiento, y considerar factores no sólo económicos sino también sociales, así como los limitantes actuales para acceder a la diversidad internacional. Este artículo presenta una revisión sobre la importancia de la conservación de los recursos genéticos vegetales, animales y de microorganismos de la agrobiodiversidad, e incluye una discusión y algunos aspectos requeridos para la priorización de taxones y tipo de materiales que se deben incluir en el proceso. Para ello, se parte de la premisa de que la conservación de la diversidad genética sirve para la realización de procesos de valor agregado y de utilización posterior.  </p><p> </p><p><strong>Agrobiodiversity genetic resources conservation for the development of sustainable production systems</strong>  </p><p>Human population growth and environmental changes require the availability of genetic diversity for the development of sustainable, efficient and competitive production systems. This means collection, conservation and characterization of the attributes present in the genetic resources of current important taxa and wild related, and promising species with development potential, which is magnified for a current genetic erosion. It requires complementary ex situ and in situ conservation strategies as well as prioritization of the diversity to be included in the process, due to the conservation costs, considering not only economic values, but also social aspects and the access limitations to genetic resources at international level. The current paper includes a revision related to the importance of the conservation of the plant, animal and microorganisms genetic resources, concerned to agrobiodiversity, with some discussion related to this topic, as well as aspects to be considered for the priorities of species and type of materials to be conserved. For such purpose, the premise is that such diversity, after added-value processes, could be used for the development of sustainable agricultural production systems. </p>
