Estos bosques juegan un papel clave en la regulación hídrica y en la estabilización del clima. Son también el hogar de muchas comunidades, incluyendo comunidades indígenas, y una fuente importante de actividad económica para sus poblaciones y los países en su conjunto. Sin embargo, la degradación forestal es un problema cada vez más grave que requiere una respuesta más inmediata y completa. Este estudio contribuye a este cometido realizando un análisis de las cadenas de valor forestal (CdV) en Ecuador, como parte de una serie de estudios por país para los cinco países de la Región Andina. Asimismo, se elaboran recomendaciones sobre acciones que se pueden tomar para fomentar una mayor productividad en ellas, salvaguardando mejor el medio ambiente y las comunidades.

Next to these forests there are abandoned agricultural areas in which native vegetation is regenerating. The dynamics of that natural regeneration is poorly understood. The objective of the work was to define groups of tree species based on their regeneration pattern in these areas. To do that, the diameter distribution of the tree cover of an area in natural regeneration for 33 years in a Brazilian biological reserve was analyzed by species. 195 trees (813 trees ha-1 47.8 ± 95.6 trees per hectare) were inventoried on 2,400 m2, belonging to 15 families and 17 species, with a quadratic mean diameter of 13.7 cm and basal area averaging 11.9 m2 ha-1. Although 73 % of the diameters ranged from 5 to 15 cm, the diameter distribution was satisfactorily fitted to the Gauss curve. Only five species presented more than 75 trees ha-1: Cecropia catarinensis, Miconia cinnamomifolia, and Miconia multiflora presented distribution with a tendency to normal, while Piptocarpha macropoda presented an inverted J shape; Vismia guianensis only appeared in the lowest diameter class. Integrating into a dendrogram the dispersion syndrome, ecological group, and wood density attributed to the sampled species, five functional groups were distinguished. Due to its homogeneity coefficient, the surveyed stand was classified as an uneven forest. Despite 33 years having elapsed since the start of the natural regeneration, the forest stand is still in an initial stage of its natural succession towards climax structures.

Se encontró un total de 72 especies arbóreas pertenecientes a 62 géneros y 35 familias, de las cuales el 29% (21 especies), son consideradas maderables con valor comercial. El mayor potencial maderable comercial fue encontrado en el SSP de pasturas con árboles dispersos de Pinus oocarpa. Este SSP es el más abundante en las fincas estudiadas (77%), con una densidad promedio de latizales y fustales de 156 árboles ha-1 y de 43 brinzales ha-1. De igual forma, presenta un volumen comercial promedio de 71,5 m 3 ha-1. De las 35 fincas inventariadas se seleccionaron ocho al azar (cuatro pequeñas y cuatro medianas), para conocer la contribución del componente maderable en la rentabilidad de las mismas. Los análisis financieros mostraron que en el caso de las fincas medianas, la contribución del VAN fue de 384,8 USD ha-1 y para las fincas pequeñas el aporte fue de 269,7 USD ha-1 , equivalente a un 27 y 70% adicional a los ingresos obtenidos por la actividad ganadera, respectivamente.

Table ES-1 | Average net present value of a program to initiate restoration of 20 Mha of degraded land in Latin America and the Caribbean by 2020 ($/ha) a WOOD FOREST PRODUCTS b Products that imply a reduction, albeit temporary, in the standing forest biomass; a long rotation cycle of 40 years for wood products is used. 170 NON-WOOD FOREST PRODUCTS Products that do not necessarily affect the standing forest; for example, medicinal and animal products, fruit, nuts, and other tree crops. 245 ECOTOURISM INCOME Income from forest-generated tourism revenues. 161 AGRICULTURAL PRODUCTS Net gains in productivity from key staple crops-using maize, soy, wheat as representative of a mix of agricultural products. This benefit assumes the deployment of sustainable practices and mosaic approaches that integrate trees into mixed-use landscapes, such as agricultural lands and settlements. 274 AVOIDED FOOD SECURITY COSTS Avoided agricultural insurance premiums resulting from enhanced output as a proxy of agricultural losses. 19 CARBON SEQUESTERED The valuation of carbon stocks stored in vegetation of restored landscapes. 270 TOTAL (ROUNDED) 1,140 Notes: a. The study assumes that 20 million hectares (Mha) under restoration are distributed across biomes with varying degrees of degradation found across the region (wet biomes are 51 percent of degraded lands in the region; dry biomes are 48 percent; temperate biomes are 1 percent) or are assumed to be distributed across the region's degraded landscapes (lightly degraded landscapes are 34 percent; moderately degraded are 58 percent; and severely degraded are 8 percent). The assessment assumes that Initiative 20x20 will result in reforestation of 13 million hectares, and improved land functionality on 7 million hectares of agricultural landscapes. b. Although wood forest products are considered to be one of the benefits of restoration, in this study we considered their monetization-based on short rotation periods and cutting methods associated with temperate lumber operations-to be less consistent with the long-term goal of land restoration. Instead, the analysis uses a 40-year cycle (similar to the estimates used for monetizing temporary carbon storage credits), thus dampening the expected stream of revenues from wood forest products in the assessment's projections.

The main question has been whether forestry should concentrate on intensively managed plantation forests or place more attention on the sustainable management of natural forests. However, this question represents a false controversy.

Thus an increasing number of national and international initiatives defined C&I sets for certification, monitoring and auditing of forest management. Because of the variety of C&I applications and the heterogeneity of C&I users, the demands and requirements on C&I in relation to application, evaluation and interpretation are diverse. To ensure viability and acceptance of C&I based forest management tools, this diversity has to be considered in the process of developing C&I sets. Based on a revision of C&I initiatives in Latin America, experiences made by the Center for International Forestry Research (CIFOR) and consultations with experts, the paper identifies and discusses the demands and requirements related to the application of C&I and its practical implications.

Se concluye que a pesar de la existencia de un potencial biofísico para el ecoturismo, la organización comunitaria en el área no está preparada para explotar las posibilidades ecoturísticas de la zona, e institucionalmente no existen mecanismos consistentes para solventar las falencias prioritarias de tales organizaciones. This article presents the results of a research carried out at La Cangreja National Park, where three of these factors were investigated. Firstly, the biophysical characteristics of the Park were assessed in order to determine its ecotourism potential. Secondly, an analysis of local communal organizations was made to estimate their capacity of developing locally-based ecotourism initiatives. Lastly, a dialogue with institutional entities from the government and other sectors was established in order to evaluate the compatibility between the mechanisms of support managed by such institutions and the primary requirements of the communal organizations. It is concluded that despite considerable biophysical potential, the organizational capacity in the area assessed is poorly developed to exploit it. At the institutional level, there are mechanisms to promote ecotourism, but they fail to attend the immediate needs of local organizations and inhabitants
