Towards a spatial framework for transfrontier conservation planning in die SADC region

Van der Merwe, Nadia 04 1900 (has links)
Thesis (MSc)--Stellenbosch University, 2003. / ENGLISH ABSTRACT: The Peace Parks Foundation (PPF) was established in 1997 to facilitate Transfrontier Conservation (TFCA) initiatives in the SADC region and thereby support economic development, conservation of biodiversity, as well as the promotion of regional peace and stability. To this effect, their regional planners require a thorough knowledge of the condition of areas in which the estimated actions will be carried out. To date, the PPF have used base datasets, such as land cover and population densities, in their GIS projects to support their decision making processes. However, they have realised the importance of developing rigorous methods for the extraction and generalization of biodiversity information for informed conservation decisions. The main aim of this study was, therefore, to develop a spatial framework for the generalisation and integration of data to become meaningful information that may be readily interpreted. The resultant framework represents a methodology for, firstly, identifying and, secondly, prioritizing core natural areas or units (CNU). CNUs were modelled to represent large blocks (minimum 100 km') of contiguous natural vegetation that are far from major roads and densely populated places. They were, then, ranked into three classes of importance (low, medium and high) according to an ecological value derived for each. This made the framework comprehensive in its considerations of regional biodiversity and robust enough to be used for planning at the SADC scale. By organising data and quantitative approaches logically in a robust, but rigorous, way, spatial frameworks provide the structure for combining specialized knowledge as well as scientific analysis and pragmatic politics in an effective planning process. This could guide plans which are proactive instead of reactive, visionary as well as pragmatic and well founded in research and understanding. / AFRIKAANSE OPSOMMING: Die Peace Parks Foundation (PPF) was gestig in 1997 om oorgrens bewarings-initiatiewe in die SADC streek te fasiliteer en daardeur steun te verleen aan ekonomiese ontwikkeling, die bewaring van biodiversiteit asook die bevordering van vrede en stabiliteit in die streek. Om dit te behaal benodig die betrokke streeksbeplanners 'n grondige kennis van die toestand van die areas waarin die beoogdede aksies uitgevoer sal word. Tot op hede het die PPF basis datastelle, van byvoorbeeld landgebruik en populasie-digtheid, ingespan m hul GIS projekte om besluitnemingsprossese te ondersteun. Daar is egter besef dat dit van hoogste belang is om deeglike metodes te onwikkel vir die onttrekking van biodiversiteits-informasie sodat ingeligte besluitneming moontlik gemaak kan word. Gevolglik was die hoof oogmerk van hierdie studie om 'n ruimtelike verwysingsraamwerk te ontwikkel wat data kan veralgemeen en integreer tot betekenisvolle inligting wat geredelik interpreteerbaar is. Die daaruit-vloeiende raamwerk stel 'n metodologie voor wat Kern Natuurlike Areas (KNA) eerstens kan identifiseer en tweedens kan prioritiseer. Hierdie KNA is gemodelleer om groot blokke (minstens 100km2 ) van aaneenlopende natuurlike plantegroei, ver van hoofpaaie en dig bevolkte gebiede, voor te stel. Hulle is hieropvolgend gesorteer in drie range van belangrikheid (laag, medium en hoog) na gelang van 'n ekologiese waarde wat vir elk afgelei is. Hierdeur is die raamwerk, in terme van voldoende oorwegings teenoor streeks-biodiversiteit, omvattend gemaak en terselfdertyd robuus vir beplanning op die SADC skaal. Deur data en kwalitatiewe benaderings logies en in 'n deeglike en robuuste wyse te organiseer, bied ruimtelike verwysingsraamwerke die struktuur om gespesialiseerde kennis met wetenskaplike analise en pragmatiese politiek te kombineer in 'n effektiewe beplanningsproses. Hierdeur kan planne geformuleer word wat proaktief is instede van reaktief, visionêr sowel as pragmaties, en terselfdertyd goed gefundeer bly op navorsing en begrip.

Orientador: Maurício Cesar Delamaro / Coorientador: Rodolfo Jose Sabiá / Banca: Fernado Augusto Silva Marins / Banca: Paulo Valladares Soares / Banca: Roberto do Santos Bartholo Junior / Banca: Francisco do Ó de Lima Junior / Resumo: Compreender o meio ambiente como um sistema frágil e limitado é uma necessidade atual e somente por meio de estratégias e ferramentas voltadas para a sustentabilidade socioambiental dos recortes locais pode-se pensar no equilíbrio de áreas de proteção ambiental, como é o caso da APA da Chapada do Araripe. Neste recorte espacial, a atividade turística encontra-se em forte expansão e é relevante as preocupações em busca de tornar a atividade compatível com a preservação e a conservação desse ambiente destino. Parte integrante dos equipamentos turístico, os meios de hospedagens são reconhecidos na literatura consultada como uma atividade geradora de significativos impactos ao meio ambiente e, quando instalados em áreas de ecossistemas frágeis, demandam intervenções que possam orientar e disciplinar o uso desse espaço. Fiel ao principio que a sustentabilidade é sempre situada, esta tese teve como objetivo geral identificar os fatores críticos para a promoção de negócios hoteleiros sustentáveis na APA Chapada do Araripe, e como objetivos específicos historiar a evolução da intervenção humana na área da APA Chapada do Araripe, identificar os principais impactos gerados pelas atividades econômicas atuais e rastrear os indicadores mais significativos para a construção de uma hotelaria sustentável para esta unidade de conservação e por fim, propor uma norma situada que possa nortear os meios de hospedagens na busca de uma gestão sustentável para a atividade.

Only through strategies and tools geared to the socio-environmental sustainability of local cuts may one think of the balance of environmental protection areas such as the APA (place for forest protection) in the Chapada of Araripe. In this spatial cut, tourism activity is in strong expansion and concerns are relevant in seeking to make the activity compatible with the preservation and conservation of these destination environments. An integral part of tourism equipment, lodging facilities are recognized in the literature as an activity that generates significant impacts to the environment and when installed in areas of fragile ecosystems require interventions that can guide and discipline the use of this space. Faithful to the principle that sustainability is always located, this thesis had, as general objective, to identify the critical factors for the promotion of sustainable hotel business in the APA in the Chapada do Araripe, and as specific goals to record the evolution of human intervention in the APA area. Identify the main impacts generated by the current economic activities and trace the most significant indicators for the construction of a sustainable hotel for this conservation unit and, finally, propose a situated norm that can guide the means of lodging in the search of sustainable management for the activity.

This study aims to evaluate the potential for the creation of protected areas according to the SNUC in Vitassay and Rosa Pinhal in the municipality of Boituva and was organized in two articles. In a rticle 1 , the areas were evaluated trough the scoring method, where areas were scored in 11 pre - established criteria. These criteria were analyzed through phytosociological study, rapid ecological assessment and landscape analisys . The score was summed and converted to a scale from 0 to 100 . Fragment 1 (Vitassay) scored 53,48 and Rosa Pinhal scored 76,74 points in 100 possible. The conclusion was that Vitassay can become an "Area of ecological interest" , a sustainable use conservation unit, and Ro sa Pinhal may be settled to an i ntegral p rotection conse rvation unit such as " Natural Municipal Park" . In article 2 w as conducted a phyt osociological analysis trhough plots method. 12 plots of 10x10m w ere demarcated in each of the fragments, distributed in two blocks containing six parcels each, forming a set of 20x30m , measuring 600m² in each of the four areas, 1200m² in Rosa Pinhal and other 1200m² in Vitassay, totaling an area of 2400m² sampled vegetation. The calculations were made using the Fitopac 2.1 application. They sampled 365 individuals belonging to 82 spe cies, 171 individuals and 46 species in the area Rosa Pinhal, and 1 94 individuals and 4 8 species in Vitassay area. The Shannon diversity index (H ') was 3.473 in Rosa Pinhal and 3 . 463 in Vitassay. In Rosa Pinhal the ten species with higher cover values (IV C) totaled 64.5% of the total IVC and , in Vitassay , summed 70.23% of the total IVC. Related to the successional groups in Rosa Pinhal area only 17.3% (8 species) species are pioneers and 67.3% (31 species) not pioneers. In Vitassay 34% (16 species) are pio nner and, 59.5% (28 species) are not pioneer s . Four endangered species were found in Rosa Pinhal and three in Vitassay. The results and analysis allowed the construction of a diagnosis of Vitassay and Rosa Pinhal fragments in the municipality of Boituva an d it was found that both areas have characteristics that favor conservation due to the presence of endangered species and diversity found in this fragments. / Da contínua preocupação com os problemas ambientais e a finitude dos recursos naturais, surge a necessidade da criação de espaços especiais para a manutenção da natureza e conservação da biodiversidade - essas áreas são denominadas Unidades de Conservação (UCs). Este trabalho tem como objetivo avaliar o potenc ial para criação de unidades de conservação de acordo com o Sistema Nacional de Unidades de Conservação ( SNUC ) nas áreas Vitassay e Rosa Pinhal no Município de Boituva e foi organizado em dois artigos. No artigo 1 foi utilizado o método de pontuação avalia ndo 11 critérios pré - estabelecidos. Esses critérios foram avaliados através de uma análise de paisagem , estudo fitossociológico, e análise da integridade biótica. A pontuação foi somada e convertida para uma escala de 0 a 100. No fragmento 1 (Vitassay) a pontuação foi de 51,16 e no fragmento 2 (Rosa Pinhal) de 76,74 de 100 possíveis . Concluiu - se que Vitassay pode se tornar uma “Área de relevante interesse ecológico” UC de Uso Sustentável e Rosa Pinhal possui vocação para UC de Proteção Integral como “Parqu e Natural Municipal”. No artigo 2 foi feita uma análise fitossociológica utilizando o método de par celas. F oram demar cadas em cada um dos fragmentos 12 parcelas de 10x10m distribuídas em 2 blocos contendo 6 parcelas cada formando um conjunto de 20x30m (600 m²) em cada uma das 4 áreas sendo 1200m² em Rosa Pinhal e outros 1200m² em Vitassay, totalizando assim uma área de 2400m² de vegetação amostrada. Os cálculos foram realizados utilizando o aplicativo FITOPAC 2.1. Foram amostrados 365 indivíduos pertencentes a 82 espécies, sendo 171 indivíduos e 46 espécies na área Rosa Pinhal, e 1 94 indivíduos e 4 8 espécies na área Vitassay. O índice de diversidade de Shannon (H’) foi de 3,473 em Rosa Pinhal e 3,463 em Vitassay. Em Rosa Pinhal as dez espécies com maior valor de cobertura (IVC) somaram 64,5% do IVC total e em Vitassay somaram 70,23% do IVC total. No que diz respeito ao grupo ecológico na área Rosa Pinhal percebe - se que apenas 17,3% (8 espécies) das espécies são pioneiras, 67,3% (31 espécies) não pioneiras. Na área Vitassay visualiza - se uma maior quantidade de espécies pioneiras 34% (16 espécies), 59,5% (28 espécies) não pioneiras. Foram encontradas 4 espécies ameaçadas em Rosa Pinhal e 3 em Vitassay. Desa forma foi possível construir um diagnóstico dos fragment os Vitassay e Rosa Pinhal e verificou - se que ambas as áreas possuem características que favorecem a conservação devido à presença de espécies ameaçadas e d a diversidade encontrada nos fragmentos.

Estrutura genética e diversidade clonal de jatobá-do-cerrado (Hymenaea stigonocarpa Mart. ex Hayne) em duas populações no Cerrado do Estado de São Paulo / Genetic structure and clonal diversity of jatobá-do-cerrado (Hymenaea stigonocarpa Mart. ex Hayne) in two populations of the Cerrado in the State of São Paulo

Maria Andréia Moreno 26 June 2009 (has links)
Este trabalho teve como objetivo avaliar a estrutura populacional e genética de Hymenaea stigonocarpa Mart. ex Hayne em duas áreas no Cerrado do Estado de São Paulo. Para tanto, foram transferidos oito iniciadores microssatélites nucleares (SSR) de Hymenaea courbaril para H. stigonocarpa, além de cinco iniciadores microssatélites cloroplastidiais (cpSSR) universais. O presente trabalho respondeu às hipóteses sobre a dispersão restrita de sementes, a existência de propagação vegetativa e a viabilidade evolutiva das populações nas unidades de conservação analisadas. O estudo foi conduzido em duas unidades de conservação administradas pelo Instituto Florestal do Estado de São Paulo e representam alguns dos últimos remanescentes protegidos de Cerrado no Estado, com fisionomias e históricos contrastantes. Na população localizada na Estação Ecológica de Itirapina (EEI), Itirapina, S.P., foram encontrados 68 indivíduos de H. stigonocarpa dispostos em reboleiras. Utilizando marcadores SSR, foram constatados apenas 18 genótipos diferentes (genetes), evidenciando a propagação vegetativa na EEI. Apesar do número reduzido de genetes na área, esta população apresentou excesso de heterozigotos. Mesmo assim, a área mínima viável para conservação ( AMV ) foi maior do que a área total da EEI devido à baixa densidade de indivíduos. A análise de paternidade, utilizando todas as sementes disponíveis na EEI (n = 71), revelou que 42,46% tiveram doadores de pólen fora na área amostrada e o tamanho efetivo de vizinhança de polinização foi de 1.283 ha, mostrando a importância da preservação de áreas particulares ou a expansão da unidade de conservação. Houve dominância de doadores de pólen e a distância média de polinização foi de 2.325 m, variando de 0,35 a 3.570 m. Além disso, os marcadores cpSSR revelaram um forte efeito fundador, com a existência de um único haplótipo. Contrastando com a EEI, a população estudada na Estação Ecológica de Assis e na Floresta Estadual de Assis (EEA) apresentou 47 indivíduos distintos geneticamente (genetes). O uso de marcadores SSR na população da EEA revelou um alto e significativo índice de fixação ( f = 0,177), associado a uma significativa estrutura genética espacial (EGE) ( xy q = 0,075) até 750 m. A EGE foi resultante de uma dispersão restrita de sementes, comprovada pelo uso de marcadores cpSSR. A alta divergência genética demonstrada pelos marcadores SSR e o número de haplótipos privados encontrado na população da EEA fez com que cada população fosse considerada uma Unidade Independente para o Manejo (UIM) e, ao mesmo tempo uma Unidade Evolutiva Significativa (USE). Essas designações implicam que, apesar das populações da EEA e da EEI possuírem um tamanho efetivo ( e N ) e uma AMV insuficientes para a manutenção da endogamia local de H. stigonocarpa em curto prazo, a localização específica dessas unidades permitiu englobar reservatórios gênicos distintos, importantes para se iniciar uma conservação evolutivo-adaptativa. Assim, programas visando a restauração florestal ou melhoramento de H. stigonocarpa devem contemplar genótipos de cada USE. Além disso, a coleta de sementes visando a conservação deve obedecer a uma distância mínima de 750 m quando os indivíduos não estiverem dispostos em reboleiras. / This study aimed to evaluate the population and genetic structure of Hymenaea stigonocarpa Mart. ex Hayne in two areas of Cerrado in the State of São Paulo. For this, eight nuclear microsatellite (SSR) primers from Hymenaea courbaril and five universal chloroplastidial microsatellite primers (cpSSR) were transferred from Hymenaea coubaril to H. stigonocarpa. This study answered the assumptions regarding restricted seed dispersal, vegetative propagation and the existence of the populations evolutionary viability in the studied conservation units. This study was conducted in two protected areas managed by the Forest Institute State of São Paulo and represent some of the last protected remnants of Cerrado in the State with contrasting physiognomies and history. The 68 trees of H. stigonocarpa on the population located in the Ecological Station of Itirapina (ESI), Itirapina, S.P., were spatially clumped. Using SSR markers only 18 different genotypes (genets) were found, showing the existence of vegetative propagation in ESI. Despite the limited number of genets in the area, this population showed an excess of heterozygotes. Even so, the minimum viable area for conservation ( AMV ) was greater than the total area of the ESI due to low density of individuals. The paternity analysis using all the available seeds in ESI (n = 71) revealed that 42.46% of pollen donors were outside the sampled area and the effective neighborhood size of pollination was 1283 ha demonstrating the importance of surrounding areas and the expansion of the protected area. There was pollen donor dominance and the average distance of pollination was 2325 m, ranging from 0.35 to 3570 m. Furthermore, the markers cpSSR revealed a strong founder effect, with the existence of a single haplotype. In contrast to the ESI, the population studied in the Ecological Station of Assis and in the Assis State Forest (EEA), had 47 trees, all genets. The use of SSR markers in the population of the ESA revealed a high and significant fixation index ( f = 0177), associated with a significant spatial genetic structure (SGS) ( xy q = 0075) up to 750 m. The SGS was originated by a limited seed dispersal, as evidenced by the use of cpSSR markers. The high genetic divergence shown by SSR markers and the number of private haplotypes found in the population of the ESA are reasons to consider each population independent units for management (IUM) and at the same time an Evolutionary Significant Unit (ESU). These designations mean that, in despite of the populations of the ESI and ESA have insufficient effective sizes ( e N ) and AMV for the maintenance of H. stigonocarpa inbreeding level in the short term, the specific location of these units allowed to include different gene pools, important in starting an adaptive-evolutionary conservation. Thus, programs aimed at forest restoration or breeding of H. stigonocarpa shall address each ESU genotypes. Moreover, the collection of seeds for conservation should have a minimum distance of 750 m among trees, when these are not clumped.

Benefits beyond boundaries : cross-border tourism collaboration in southern African transfrontier conservation areas

Wyllie, Richard January 2014 (has links)
"In a world beset by conflict and division, peace is one of the cornerstones of the future. Peace parks are building blocks in this process, not only in our region, but potentially in the entire world." These words of the l ate- former President Nelson Mandela of South Africa on the concept of Peace Parks, underl ines their importance beyond the na tural into the human domain . This disser ta tion focusses on an understanding o f Peace Parks or Transfrontier Conservat ion Areas (TFCAs) in the context of southern Africa and shows how c ol laboration can be used as a tool for the development o f these a re as . T h e t hr ee m ai n a im s of “TFC As ” are t o co nse rv e bio lo gic al d iversity, crea te a plat form for pover ty allevia tion and most importantl y, to promote a culture of peace amongst all nati ons i nvol ved in their development. In order to address this concept, the Great Limpopo Transfront ier Conservation Area (GLTFCA) i s used as an example of how South Africa, Mozambique and Zimbabwe are col laborating their ef for ts towards common goals in terms of biological conserva tion and pover ty alleviation as wel l tou rism and economic development .
