The process of forest conservation in Vanuatu : a study in ecological economics

Tacconi, Luca, Economics & Management, Australian Defence Force Academy, UNSW January 1995 (has links)
The objective of this thesis is to develop an ecological economic framework for the assessment and establishment of protected areas (PAs) that are aimed at conserving forests and biodiversity. The framework is intended to be both rigorous and relevant to the decision-making process. Constructivism is adopted as the paradigm guiding the research process of the thesis, after firstly examining also positivist philosophy and ???post-normal??? scientific methodology. The tenets of both ecological and environmental economics are then discussed. An expanded model of human behaviour, which includes facets derived from institutional economics and socioeconomics as well as aspects of neoclassical economics, is outlined. The framework is further developed by considering, from a contractarian view point, the implications of intergenerational equity for biodiversity conservation policies. The issues of intragenerational distribution and allocation are then considered. In this regard, cost-benefit analysis (CBA), as applied to the valuation of forests, PAs, and biodiversity, is critically reviewed. A participatory approach to decision-making, which may also include CBA, is then proposed. The resulting ecological economic framework may be thus summarised: (a) ecosystem use patterns should be chosen on the basis of their sustainability, distributional, and efficiency aspects; (b) systems of PAs should be established in order to achieve minimal intergenerational equity; (c) intragenerational equity requires the correction of the asymmetrical distribution of the costs and benefits arising from the establishment of PAs; (d) the institutional features relevant to the environmental-economic issues being analysed should be considered; and (e) the decision-making process should be participatory and action oriented. The framework is applied to two case studies in Vanuatu. These applications detail (a) stakeholders??? views and trade-offs faced in relation to forest management (b) modes of participatory research and decision-making, (c) forms of compensation that may be adopted in correcting asymmetrical distributions of the costs and benefits of PAs, and (d) institutional influences on ecosystems use and implications for conservation projects. The institutional arrangements developed for the establishment of the PAs are presented. The application of this ecological economic framework has resulted in the formal establishment of one PA and the identification and assessment of five other PAs.

Análise morfométrica e biodiversidade da vegetação na microbacia hidrográfica da Fazenda Experimental Edgárdia /

Moreira, Lilian, 1976- January 2007 (has links)
Orientador: Valdemir Antonio Rodrigues / Banca: Antônio de Pádua Sousa / Banca: Luiza Helena Duenhas / Abstract: The preservation of the biodiversity of the vegetation in the micro watershed is of basic importance for the maintenance of the animal and vegetal wild life, ambient services and protection of the biosfera. The morphometry is a tool of great importance as diagnostic of susceptibility to the ambient degradation or conservation and guides the planning and handling of the micro watershed. The present study had as objective the morphometric characterization and analysis of biodiversity in the micro watershed of the Edgárdia Farm, Botucatu - SP. The micro watershed of the Edgárdia Farm belongs to the College of Agronomicas Ciencias/UNESP, city of Botucatu - SP. The program used for the attainment of the morphometrical variable was the ILWIS 3.2 version and the topographical letter of the IBGE with 1:50.000 scale. In the study of biodiversity four transects in the micro watershed had been installed, in the parts high (superior third), medium high and medium low (medium third) and low (inferior third) of the micro watershed, in which parcels of 10 x 5 meters had been installed. In the four transects, the forest species had been quantified and commanded in popular and classified families, species, names in its respective ecological successions (pioneer, secondary or climax). It was measured in each tree the height and the diameter in the height of the chest (DAP). The morphometrical variable and the results were: area of 7,205 kmø; perimeter of 11,59 km; length and width of micro watershed 3,578 the equal 3,016 km; length of the draining net and quotas of 15,68 km and 1100,00 km; factor of form 0,79, considered very high; density of draining of 2,18 km.kmø, classified as average; the high declivity of 76,98%, in accordance with the classes of declivities and types of relief of the micro watershed, was classified as scarped; frequency of rivers the 3,19 segments of rivers...

Conhecimento tradicional associado ao recurso genético: os desafios da legislação brasileira na tutela de interesses coletivos

Silveira, Carolini Guedes Barros da 21 August 2007 (has links)
Made available in DSpace on 2015-04-11T13:55:15Z (GMT). No. of bitstreams: 1 Carolini Siveira.pdf: 52413 bytes, checksum: fb03050abd7aca5339af29064552d74e (MD5) Previous issue date: 2007-08-21 / With the international dilemma formed, on the one hand, the countries, holders of technology, supported on the devices of the Agreement of the Rights of Intellectual Properties Related to Trade of the World Commerce Organization in order to guarantee that the genetic resources be considered common patrimony of humanity and, on the other hand, the countries, holders of genetic resources, sticked to the Convention on Biological Resources, based on the sovereignity principle of the State to explore its own resources, Law becomes fundamentally important in the intermediation of such antagonistic interests. This conflict is materialized by means of the practice known as biopiracy, which involves as much the genetic resource as the knowledge related to the mentioned resource, damaging mostly countries like Brazil. With the ratification of the Convention of Biological Diversity in 1994 and the edition of the legislation MP nº 2.186-16 in 2001, Brazil regulated affairs that involve the traditional knowledge related to genetic resource. But will this legislation take into account the interests of traditional populations? With the aim to analyse the applicability of Brazilian legislation which regulates the acess to traditional knowledge related to genetic resource of two native populations who inhabit the surroundings of Benjamin Constant city, located in the region of High Solimões River, in Amazonas, Brazil, one denominated Aldeia Kokama, of Kokama ethnic group, and the other Native community of Novo Paraíso, of Ticuna ethnic group. This research founded on the Sociological concept of Law, developed by Bourdieu (1989), and as logical sustainability the systemic abordage of Morin (2002), and employing the case study methodology, more specifically of two cases: the legislation and the human group. Thus, with the development of the research, it was been observed that Brazilian legislation, the MP nº 2.186-16, presents conceptual inaccuration and lack of practicability. With regard to the native populations of Nova Aliança and of Novo Paraíso, it was observed that these human groups develop a relation of community and live daily in an environment little modified in a region of Amazonian Forest which contains high concentration of biodiversity, demonstrating a great knowledge on the genetic resources that sorround them. Nevertheless, their lack of information and of legislative knowledge render impossible the application of such legislation rules and, consequently, the demand of their rights. The analysis of Brazilian legislation which regulates the acess to traditional knowledge related to genetic resource and of the native populations of Nova Aliança and of Novo Paraíso showed the correspondence between both, but with sorrowful confirmation of the inapplicability of the legislation for these people, caused mainly by the lack of information they showed regarding the rights due to them. / Com o dilema internacional formado, de um lado os países detentores de tecnologia, apoiados nos dispositivos do Acordo sobre Aspectos dos Direitos de Propriedade Intelectual Relacionados com o Comércio (TRIPS), da Organização Mundial do Comércio (OMC), para garantir que os recursos genéticos sejam considerados patrimônio comum da humanidade, e de outro os países de origem de recursos genéticos, agarrados à Convenção sobre Diversidade Biológica (CDB), baseada no princípio de soberania dos Estados para explorar seus próprios recursos, o Direito torna-se de fundamental importância na intermediação de interesses tão antagônicos. Esse conflito é materializado pela prática conhecida como biopirataria, a qual engloba tanto o recurso genético propriamente dito como o conhecimento que o envolve e, por isso, atinge sobremaneira países como o Brasil. Com a ratificação da CDB em 1994 e a edição da MP nº 2.186-16 em 2001, o Brasil regulamentou questões que envolvem o conhecimento tradicional associado ao recurso genético. Mas será que essa legislação mantém correspondência com os interesses das populações tradicionais? Com o intuito de analisar a aplicabilidade da legislação brasileira que regulamenta o acesso ao conhecimento tradicional associado ao recurso genético em duas populações indígenas localizadas no município de Benjamin Constant, região do Alto Solimões do estado do Amazonas, autodenominadas Aldeia Kokama Nova Aliança, de etnia kokama, e Comunidade Indígena Novo Paraíso, de etnia tikuna, utilizamos como base teórica desta pesquisa o conceito sociológico de Direito desenvolvido por Bourdieu (1989) e como sustentabilidade lógica a abordagem sistêmica de Morin (2002), tendo sido empregada a metodologia estudo de caso, mais especificamente de dois casos: a legislação e o grupo humano. Nesse sentido, com o desenvolvimento do estudo, pode-se dizer que a legislação brasileira, aqui representada pela MP nº 2.186-16, apresenta imprecisão conceitual e falta de executividade. No que tange às populações indígenas de Nova Aliança e de Novo Paraíso, afirma-se que são grupos humanos que transmitem uma relação de coletividade e por conviverem diariamente com um ambiente natural pouco modificado, em uma zona da F loresta Amazônica de alta concentração de biodiversidade, demonstram ter um grande conhecimento sobre os recursos genéticos que os cercam. No entanto, a falta de informação e preparação legislativa desses povos impossibilita a aplicação de tais normas e, conseqüentemente, a exigência de seus direitos. A análise da legislação brasileira que regulamenta o acesso ao conhecimento tradicional associado ao recurso genético e das populações indígenas de Nova Aliança e de Novo Paraíso demonstrou correspondência entre ambas, mas com a triste constatação de negativa de aplicabilidade da legislação a esses povos, ocasionada principalmente pela falta de informação que evidenciaram quanto aos direitos assegurados a eles

Biflödens effekt på mångfald och abundans av växter i strandzonen utmed älvar : Test av hydrochorins effekt och den longitudinella teorin / The effect of tributaries on plant species diversity and abundancy in river riparian zones : Test of the effects of hydrochory and the longitudinal build up theory

Berger, Daniel January 2023 (has links)
The riparian zone is a changeable and species-rich habitat with important ecological functions that have long been affected by human activities such as hydropower and forestry. Rivers and their adjacent riparian zones also constitute a transport route for plant parts and seeds in a form of passive transport, called hydrochory, which can contribute to the establishment of plants or the preservation of diversity in the riparian zone. Theories such as "the river collector hypothesis" state that the diversity of plants increases with distance from the source of a river and this study aims to investigate a specific part of this theory, namely the effect of tributaries on the accumulation of plants in the riparian zone. Plant surveys have been carried out upstream and downstream of the outlets of several tributaries to Vindelälven (unregulated) and Umeälven (regulated) in Västerbotten County, Sweden, to compare these locations with each other. Species numbers and effective species numbers for upstream and downstream surveys were analysed using paired t-tests with the expectation that both species numbers and effective species numbers would be higher downstream of tributaries than upstream. The results showed no significant differences between the upstream and downstream inventories. When examining the data, there was an indication of a trend of higher species numbers and effective species numbers downstream of tributaries in the Umeälven, but further research is needed to investigate possible connections. The explanation of the effect of tributaries on the diversity of plants in the riparian zone may be more complicated than can be explained only by theories of the accumulation of plants from hydrochory. Alternatively, the effect from the tributaries is small in relation to the longitudinal build-up of plants that occurs in longer free-flowing stretches of the rivers, which may hide the effect of the tributaries. / Strandzonen är ett föränderligt och artrikt habitat med viktiga ekologiska funktioner som under lång tid har påverkats av mänskliga verksamheter som vattenkraft och skogsbruk. Älvar och dess angränsande strandzoner utgör även en transportsträcka för växtdelar och fröer i en form av passiv transport, benämnd hydrochori, som kan bidra till etableringen av växter eller bevarandet av mångfalden i strandzonen. Teorier som ”the river collector hypothesis” säger att mångfalden av växter ökar med avstånd från källan i en älv och den här studien har som mål att undersöka en specifik del av denna teori, nämligen vilken effekt biflöden har på ansamlingen av växter i strandzonen. Växtinventeringar har genomförts uppströms och nedströms om flera biflödens utlopp till Vindelälven (oreglerad) och Umeälven (reglerad) i Västerbottens län för att jämföra dessa lokaler med varandra. Artantal och effektivt artantal för uppströms- och nedströmsinventeringar analyserades med parade t-tester med förväntningen att både artantalet och det effektiva artantalet skulle vara större nedströms om biflöden än uppströms. Resultaten visade inga signifikanta skillnader mellan uppströms- och nedströmsinventeringarna. Vid granskning av data fanns en antydan till en trend med större artantal och effektivt artantal nedströms om biflöden i Umeälven men ytterligare undersökningar behövs för att utreda eventuella samband. Förklaringen till vilken effekt biflöden har på mångfalden av växter i strandzonen kan vara mer komplicerad än att det på egen hand kan förklaras med teorier om ansamling av växter från hydrochori. Alternativt är effekten från biflödena liten i relation till den longitudinella uppbyggnaden av växter som sker i längre fritt flödande sträckor av älvarna vilket skulle kunna dölja biflödenas effekt.

To do or not to do : dealing with the dilemma of intervention in Swedish nature conservation

Steinwall, Anders January 2016 (has links)
Nature conservation is often seen as being primarily about shielding parts of nature from human intervention, e.g. by protecting areas. Over the last decades, however, intervention is increasingly being seen as necessary for nature to regain or retain its values, through ecological restoration and active management. This complicates simple assumptions that ‘nature knows best’ and raises dilemmas which are hotly debated in the scholarly literature around ecological restoration, protected area management, environmental ethics and green political theory. However, how these dilemmas are dealt with in actual policy struggles among the conservation professionals who make management decisions is less studied. This thesis explores how issues regarding active intervention in nature are represented, debated and institutionalized within Swedish nature conservation, and to what effect. The empirical focus lies on policy struggles around the designation and management of protected forests and around efforts to save a nationally threatened bird species, the white-backed woodpecker. My analytical framework is informed by Argumentative Discourse Analysis and Political Discourse Theory, to which I contribute a further elaboration of the notion of discourse institutionalization. Based on documents and interviews with conservation professionals, I identify competing articulations of the ends and means of conservation and relate these to scholarly debates around ecological restoration and interventionist conservation management. The analysis further focuses on how elements of the different policy discourses are institutionalized in rules, routines or official policy documents. Two main competing policy discourses are found: one focused on leaving pristine nature to develop freely, and one focused on active, adaptive management for biodiversity. While the former has previously been said to characterize the Swedish conservation bureaucracy, my analysis shows it is now widely seen as outdated. Arguments which in the scholarly literature are associated with an ethically informed defense of nature’s autonomy are here dismissed as emotional, aesthetic and thus unscientific concerns, delegitimizing them within the rational, science-based public administration for nature conservation. In contrast, biodiversity is broadly forwarded as a self-evident goal for active intervention, in line with both science and policy requirements. Adaptive management for biodiversity is in that sense the dominant discourse. Still, the older discourse is institutionalized in the purposes and management plans of existing nature reserves, and its defenders have also succeeded in strengthening that institutionalization through new and more restrictive guidelines. The findings suggest that this has been possible not only because of the gate-keeping role of a few centrally placed actors, but also because their restrictive stance resonates with the outside threat of exploitation which organizes the common order of discourse. Naturalness, a term described as irrelevant by some proponents of adaptive management for biodiversity, is also shown to remain a shared concern in several ways. The results thus highlight the importance of both entrenched common sense and institutionalization of certain logics or arguments in authoritative documents. The main theoretical contribution of the thesis consists in clarifying the effects of such discourse institutionalization — using the terms durability, legibility and leverage — and showing how the processes of negotiation, re-interpretation and modification of institutions are more dynamic than some accounts of discourse institutionalization suggest. Rather than trying to resolve (and thus remove) the dilemma of intervention, the thesis points to the importance of keeping open discussion of the ultimately unanswerable questions about intervention in nature alive in both theory and practice. / Ecosystem restoration in policy and practice: restore, develop, adapt (RESTORE)
