Subsídios para o planejamento estratégico costeiro do município de Jaguaruna, Santa Catarina

The unplanned occupation of the Coastal Zone has promoted the replacement of the original natural environment by the anthropic environment. This transformation generates conditions that unbalance the Environmental Diversity (abiotic and biotic natures) and prejudice the anthropic environment. This problem tends to continue and worsen in small municipalities; as is the case of municipality of Jaguaruna, Santa Catarina, Brazil. The present paper presents the method of structuring the irst steps of a coastal strategic plan developed in Camacho Balneary/Jaguaruna through actions and scenarios of management based on conlict conditions mapping, the application of the Legal - Environmental Criticality Index (ICLA, in Portuguese), the paradigm of Geodiversity and the local sedimentary dynamics. In a Geographic Information System environment, the regionalization of the Environmental Diversity landscape was carried out by "map algebra" of abiotic and biotic information. After identifying and ranking the main conlict conditions by applying the ICLA, each conlict condition with an area over 1,000 m2 was evaluated. There were 71 conlict conditions, which cover 79.91% of the areas occupied with urban or agricultural activities. When comparing the results with the current management instruments, the main restrictions observed were: disrespect for legal and environmental constraints of occupation; poor sanitation; territory and urban zoning incoherent with the socio-spatial dynamics of Jaguaruna; lack of inancial investment; and insuicient technical staf

Brazilian Flora 2020: Leveraging the power of a collaborative scientific network

International audienceThe shortage of reliable primary taxonomic data limits the description of biological taxa and the understanding of biodiversity patterns and processes, complicating biogeographical, ecological, and evolutionary studies. This deficit creates a significant taxonomic impediment to biodiversity research and conservation planning. The taxonomic impediment and the biodiversity crisis are widely recognized, highlighting the urgent need for reliable taxonomic data. Over the past decade, numerous countries worldwide have devoted considerable effort to Target 1 of the Global Strategy for Plant Conservation (GSPC), which called for the preparation of a working list of all known plant species by 2010 and an online world Flora by 2020. Brazil is a megadiverse country, home to more of the world's known plant species than any other country. Despite that, Flora Brasiliensis, concluded in 1906, was the last comprehensive treatment of the Brazilian flora. The lack of accurate estimates of the number of species of algae, fungi, and plants occurring in Brazil contributes to the prevailing taxonomic impediment and delays progress towards the GSPC targets. Over the past 12 years, a legion of taxonomists motivated to meet Target 1 of the GSPC, worked together to gather and integrate knowledge on the algal, plant, and fungal diversity of Brazil. Overall, a team of about 980 taxonomists joined efforts in a highly collaborative project that used cybertaxonomy to prepare an updated Flora of Brazil, showing the power of scientific collaboration to reach ambitious goals. This paper presents an overview of the Brazilian Flora 2020 and provides taxonomic and spatial updates on the algae, fungi, and plants found in one of the world's most biodiverse countries. We further identify collection gaps and summarize future goals that extend beyond 2020. Our results show that Brazil is home to 46,975 native species of algae, fungi, and plants, of which 19,669 are endemic to the country. The data compiled to date suggests that the Atlantic Rainforest might be the most diverse Brazilian domain for all plant groups except gymnosperms, which are most diverse in the Amazon. However, scientific knowledge of Brazilian diversity is still unequally distributed, with the Atlantic Rainforest and the Cerrado being the most intensively sampled and studied biomes in the country. In times of “scientific reductionism”, with botanical and mycological sciences suffering pervasive depreciation in recent decades, the first online Flora of Brazil 2020 significantly enhanced the quality and quantity of taxonomic data available for algae, fungi, and plants from Brazil. This project also made all the information freely available online, providing a firm foundation for future research and for the management, conservation, and sustainable use of the Brazilian funga and flora
