Desde 2007 at? hoje, atingiu-se aproximadamente 50 mil hectares em projetos de fomento com o vi?s protetivo. As t?cnicas utilizadas nos projetos de fomento florestal s?o a promo??o ou indu??o da regenera??o natural, o enriquecimento por meio de mudas e quando necess?rio o plantio total da ?rea com mudas de esp?cies florestais nativas de ocorr?ncia natural da regi?o. Para avaliar se tais a??es v?m atingindo os seus objetivos, se os recursos investidos est?o sendo bem empregados ou, ainda, se ser? necess?rio readequar as a??es adotadas, faz-se necess?rio avaliar e monitorar as ?reas restauradas no ?mbito do programa. Diante deste esfor?o o monitoramento destas ?reas trabalhadas permite que o programa de fomento avalie as melhorias no sentido de torn?-los mais eficazes. A proposta deste estudo foi sugerir uma metodologia para a avalia??o dos projetos de recupera??o do programa de fomento florestal, orientados por princ?pios, crit?rios e indicadores, procurando verificar as tend?ncias de sucesso dos projetos. Foram visitados aleatoriamente 19 projetos nos munic?pios de Concei??o do Mato Dentro, Datas, Diamantina, Rio Vermelho, Santo Ant?nio do Itamb? e Serro e aplicada uma matriz com os indicadores baseados em dois crit?rios de forma que qualquer servidor da autarquia tenha a capacidade de aplic?-la, sem a necessidade de especialistas para a execu??o do monitoramento. Baseando-se nas recomenda??es t?cnicas e legislativas, desenvolveram-se par?metros de refer?ncia para avaliar o estado do projeto de que foi executado. Por conta das diferentes fitofisionomias da regi?o de estudo foram elaborados par?metros de refer?ncia para a Floresta Estacional Semidecidual e Campo Rupestre. Os dados foram analisados por meio da an?lise do componente principal (PCA) e TWINSPAN. Com a metodologia proposta foi poss?vel verificar se os projetos de fomento est?o adequados quanto ?s recomenda??es t?cnicas e liter?rias. Este estudo demonstrou que ? poss?vel realizar o monitoramento dos projetos de recupera??o/ restaura??o do programa de fomento florestal do IEF. Outra caracter?stica importante pauta-se na utiliza??o de baixos recursos financeiros e apontar o desempenho dos projetos avaliados. A proposta n?o foi capaz de apontar todos os par?metros ecol?gicos, mas detecta as altera??es favor?veis e desafor?veis ? resili?ncia dos projetos de recupera??o, requerendo maiores estudos e ajustes a fim de agregar melhorias na qualidade do monitoramento. / Disserta??o (Mestrado) ?

From 2007 to present date, it reached approximately 50,000 hectares in development projects with the protective bias. The techniques used in forest development projects are the promotion or induction of natural regeneration, the enrichment trough seedlings and when it is necessary, the plantation of the whole area with seedlings of native tree species from the region. To assess whether these restore\ recovery actions are reaching their goals, whether the resources invested in these actions are being well employed, or even if it will be necessary some rearrangement in the taken actions, it was necessary to evaluate and monitor the restored areas within the program scope. Before this effort, the monitoring of these worked areas allows that the development program assess the improvement rates in order to make them more effective. This study aims to suggest an assessment methodology of the restoration projects of the forest development program, guided by principles, criteria and indicators, seeking to verify the trends of successful projects. 19 projects were randomly visited in the municipalities of Concei??o do Mato Dentro, Datas, Diamantina, Rio Vermelho, Santo Antonio do Itamb? and Serro and it was applied an array of indicators based on two criteria therefore any civil servant in the local authority would be able to apply it, without needing an expertise to perform the monitoring. Based on technical and legislative recommendations, it was developed benchmarks to assess the project status executed. Because of the different phyto-physiognomies in studied area some benchmarks were developed for the Stational Semideciduous Forest and Rupestrian Field. Data were analyzed through principal component analysis (PCA) and TWINSPAN. With the proposed methodology it was possible to verify if the development projects were suitable with literary and technical recommendations. This study demonstrates that it is possible to perform the monitoring of recovering\ restoration projects of the forest development program of the IEF. Another important feature is guided by the usage of low financial resources and it also points the performance of evaluated projects. The proposal was not able to point all ecological benchmarks, but it detects favorable and unfavorable changes concerning the resilience of the recovery projects, requiring further studies and adjustments in order to add improvements to the quality of monitoring.

In the present days, much of the world's coastlines are being affected by erosion, which causes great damage to the economy. This work had as study case the beaches of Areia Preta, Artistas, Meio and Forte located in Natal in Rio Grande do Norte. It shows as result the monitoring of the beach strip that makes possible to obtain quantitative and qualitative data, allows the study of the coastal dynamics of the beaches and the Recovery Project of the Areia Preta beach interference on adjacent beaches. This research was guided by the integrated analysis method on the systemic perspective. The pratical procedures adopted were: bibliographic research; fieldwork during eleven months (environmental characterization, collection of hydrodynamic data, topographic leveling, collection of sediments) and; sedimentological analysis of samples collected. By monitoring of the points A, B, C, D and E we were able to find the occurrence of the coastal erosion on their biggest part except by the C and D profiles. It was noted the need for the government to complete the hydraulic fill, as it made only 60% of the landfill planed. It was found that the spikes built on the beach of Areia Preta are preventing the natural transport of sediments that the longshore performs towards South-North. This interference is causing the lack of sediment on the beaches of Forte and Meio and their coastal erosion in consequence / A zona costeira tem sido estudada em escala mundial com o enfoque na eros?o costeira. Atualmente, grande parte das linhas de costa mundial est? sendo afetada pela eros?o, o que gera grande preju?zo para a economia. O trabalho teve como ?rea de estudo as praias de Areia Preta, dos Artistas, do Meio e do Forte, localizadas em Natal/RN. Apresenta como resultado o monitoramento da faixa de praia, que possibilita a obten??o de dados quantitativos e qualitativos, permite o estudo da din?mica costeira das praias e da interfer?ncia do projeto de recupera??o da praia de Areia Preta nas praias adjacentes. Esta pesquisa foi norteada pelo m?todo da an?lise integrada, na perspectiva sist?mica. Os procedimentos pr?ticos adotados foram: pesquisa bibliogr?fica; trabalho de campo durante onze meses (caracteriza??o ambiental, coleta de dados hidrodin?micos, nivelamento topogr?fico e coleta de sedimentos) e; an?lise sedimentol?gica das amostras coletadas. Atrav?s do monitoramento dos pontos A, B, C, D e E, foi poss?vel constatar a ocorr?ncia de eros?o costeira em todos os perfis. Notou-se a necessidade do poder p?blico completar o aterro hidr?ulico, j? que este efetuou apenas 60% do aterro previsto. Constatou-se que os espig?es constru?dos na praia de Areia Preta est?o impedindo o transporte natural de sedimentos, que a deriva litor?nea realiza no sentido Sul-Norte. Essa interfer?ncia est? acarretando na falta de sedimentos nas praias do Meio e do Forte e, conseq?entemente, na eros?o costeira das referidas praias
