| Community-based forest management has proliferated throughout Africa as national governments have decentralized the administration of public forestry. Community-based forestry has taken multiple forms, depending on the assortment of land-tenure systems, forest-use norms, wood demand, and social organization, among others factors. Nature, Wealth, and Power is an analytical framework that has been developed from experiences in natural resource management in Africa. In this paper, we amend the framework to People, Nature, Wealth, and Power (PNWP), and propose it as an analytical lens for community-based forest management initiatives. We use the PNWP framework to assess the responsiveness of contractual forest management in the Menabe region of Madagascar to... |

| Na iLPF os sistemas agrossilvipastoris, ao associar o componente árboreo às pastagens e às lavouras, adquirem importância, principalmente em regiões agropastoris com grande fragmentação de remanescentes florestais naturais e/ou com pastagens degradadas. A inclusão do componente árboreo ao da lavoura e da pastagem representa um avanço inovador da Integração Lavoura-Pecuária (iLP), evoluindo para o conceito de integração-Lavoura-Pecuária-Floresta (iLPF), estratégia de produção sustentável que integra atividades agrícolas, pecuárias e florestais, realizadas na mesma área, num cultivo consorciado, em sucessão ou rotação, buscando efeitos sinérgicos entre os componentes do agroecossistema, em busca da adequação ambiental, da valorização do homem e da... |

| This paper analyzes the role of afforestation-reforestation and timber management activities, and their major and secondary economic effects in stabilizing climate during the first commitment period of the Kyoto Protocol. In particular, with a Computable General Equilibrium framework, the ICES model, it is inferred how forest carbon sequestration fits within the European domestic portfolio of a 2020-20 and 2020-30 climate stabilization policy. Afforestation and land use are accounted for by introducing their effects in the model. This is done by relying on carbon sequestration curves provided by Sohngen (2005), which describe the average annual cost of sequestration for selected world regions. Results show that afforestation and timber management could... |

| O Brasil e um dos paises com maior diversidade genetica, respondendo por cerca de 30% das plantas e especies animais que ocorrem no mundo. Dentre os diferentes biomas brasileiros, os Cerrados, com seus 207 milhoes de hectares, apresenta uma grande diversidade faunistica e floristica em suas diferentes fisionomias vegetais. Ate meados deste seculo esta regiao era considerada como marginal para producao agricola, no entanto, devido ao desenvolvimento da pesquisa e de tecnologias agricolas que viabilizaram sua utilizacao em bases economicas, hoje ela e responsavel pela producao de cerca de 35% de graos e carnes do pais. O modelo de ocupacao da terra utilizado, baseado no uso intensivo de insumos e maquinas pesadas, se de um lado, no ultimos vinte anos,... |

| With a very high forest cover (over 80%) and low population density (below 5 inhbts/km2), Gabon is still a forest biodiversity rich country. Gabon's forests are amongst the richest in Africa in terms of botanical diversity and endemism for example, 22% of plants described in the Flora of Gabon are endemic and the forests of Gabon have more plant species (estimated at 8000 species) than all of the forests of West Africa combined. The fauna is also rich, estimated at more than 190 mammal species, including at least 20 species of monkeys, more than 600 species of birds, 70 species of reptiles and 100 species of amphibians. About 35,000 gorillas and 64,000 chimpanzees dwell in Gabon forests and elephants number between 60,000 and 74,000 individuals. The... |

| Greenhouse gas (GHG) removals by afforestation and reforestation project activities under the Kyoto Protocol's Clean Development Mechanism (CDM) are vulnerable to a variety of risks and uncertainties, resulting in the partial or total reversal of such removals. Hence, GHG removals from these sink activities are considered to be of temporary nature and non-permanent. Specific modalities related to non-permanence will need to be developed in order to include afforestation and reforestation project activities under the CDM and for a decision on modalities to be reached at COP 9 in December 2003. Two main options on how to address non-permanence have been proposed, these being temporary credits and insurance of emission reduction credits. This paper discusses... |

| The coastal forest communities of Kenya exist mainly as isolated blocks which show high levels of species endemism and comprise a total of about 83,800ha in a narrow belt which extends inland for about 30km. The forests are characterized by dense or moderately dense stands of tall trees, species of the genera Sterculia, Chlorophora and Memecylon. The drier woodlands include stands of Cynometra, Manilkara and Afzelia. Centuries of human occupation have reduced the forest element which was originally more extensive. Mangrove swamps occur in tidal estuaries and lagoons while coconut palms are common above high tide. A complex of many bush types occur in the high bush area. Scattered baobab trees present a striking appearance while the prevalence of mango... |

| O presente trabalho teve por objetivo avaliar os efeitos de diferentes espaçamentos de plantio sob o desempenho silvicultural do híbrido Eucalyptus grandis x E. camaldulensis, na Chapada do Araripe. O ensaio foi instalado na Estação Experimental do IPA no município de Araripina-PE, (Latitude: 7o 2750?S, Longitude: 40o 24?38?W, Altitude de 828 m), com temperatura média anual de 27o C. A precipitação média anual é de 700 mm concentrados entre os meses de fevereiro e maio. O delineamento experimental adotado foi blocos ao acaso com cinco espaçamentos: 3,0 m x 2,0 m; 3,0 m x 2,5 m; 3,0 m x 3,0 m; 3,0 m x 3,5 m e 3,0 m x 4,0 m, com quatro repetições. A área experimental foi submetida previamente à aração e gradagem e subsolagem a 40 cm de profundidade na linha... |

| Inhabitants of urban and rural areas are important participants in the process of developing and implementing forest policy. Thus, it is essential to determine their demands and attitudes towards forestry issues. In this context, the demands and evaluation of forest functions are investigated in a case study of the Turkish province of Bal kesir. The findings of the case study show that differences in terms of demands among inhabitants of rural and urban areas are related to forest fires fighting, crimes fighting, forestry-tourism integration, forestation and regeneration activities, and the enlargement of forest areas. The main differences among their assessments of forest functions are related to fire wood production, and the provision of flood and... |

| We review characteristics of birds in boreal forests in the context of their ecological sustainability under both natural and anthropogenic disturbances. We identify the underlying ecological factors associated with boreal bird populations and their variability, review the interactions between boreal bird populations and disturbance, and describe some tools on how boreal bird populations may be conserved in the future. The boreal system has historically been an area with extensive disturbance such as fire, insect outbreaks, and wind. In addition, the boreal system is vulnerable to global climate change as well as increasing pressure on forest and water resources. Current knowledge indicates that birds play an important role in boreal forests, and... |
