| The goal of the present work is to synthesize the process of collective construction developed to protect the high-altitude wetlands of the Blanco River basin, located in the Andes Mountains, Province of Mendoza. The participatory process arose out of an initiative of basin residents and users, and was conducted by the Integrative Committee for Creation of Potrerillos Municipal Environmental Protected Area (MEPA), composed of civil society organizations, government agencies and scientific institutions. The major pressures affecting the wetlands, identified through participatory assessment of the socio-ecosystem are: water pollution, reduction and total loss of habitat, stoppage of groundwater flows, artificial drainage, poldering of the meadow, and... |

| ABSTRACT Shade-tolerant forest species are among the most susceptible to habitat loss in agricultural mosaics, where a variety of croplands is connected to forests at different levels of anthropogenic disturbance. We aimed to evaluate the community similarity of shade-tolerant species among different land use types across agricultural mosaics with different levels of disturbance. The study was conducted in three municipalities in southern and southeastern Pará state, in eastern Amazonia. A multiple-community similarity measure based on the Horn similarity index was used to compare land use types and assess the resilience of shade-tolerant species towards forest loss and disturbance at the landscape level. High shade-tolerant species similarity was found... |

| This study examines the drivers of land use in a shifting cultivation system with forest fallow. Forest fallow provides on-farm soil quality benefits, local hydrological regulation, and global public goods. An optimal control model demonstrates that farmers have an incentive to fallow less than is socially optimal, though market failures limiting crop production can have a countervailing effect by encouraging fallow. An econometric model estimated using data from the Brazilian Amazon suggests that fallowing does not result from internalization of local fallow services but instead is associated with poor market access and labor and liquidity constraints. |

| Este trabalho apresenta a aptidão climática do Estado de Alagoas para oito culturas agrícolas: algodão herbáceo, cana-de-açúcar, feijão phaseolus, feijão vigna, mamona, mandioca, milho e sorgo. O estudo foi desenvolvido pela Embrapa Solos UEP Recife, em parceria com o Governo do Estado de Alagoas / Secretaria de Estado da Agricultura e Desenvolvimento Agrário, com o objetivo de gerar informações para subsidiar o planejamento e o aperfeiçoamento do uso das terras do estado. No que se refere à metodologia, foram utilizados procedimentos diferentes dos tradicionalmente adotados nos zoneamentos climáticos, os quais se baseiam nas médias históricas dos totais mensais de chuva. Nesta nova abordagem, três cenários pluviométricos foram considerados: anos secos,... |

| Práticas agrícolas, como escolha e manejo adequado do solo, utilização de cultivares adaptadas à região, adoção de espaçamentos corretos, além de calagem e adubação, irrigação, podas, polinizações manuais, controle fitossanitário de pragas, entre outras, podem levar o maracujazeiro a atingir altas produtividades. Desse modo, a Embrapa Acre coloca à disposição dos produtores, professores e extensionistas, de forma objetiva e concisa, uma importante publicação que aborda as práticas inerentes ao cultivo do maracujazeiro de forma sustentável e econômica. |

| This study describes the design and application of a stratified sampling strategy of waterbodies to assess and analyze the distribution of cyanobacteria at a regional scale (Ile-de-France, IDF). Ten groups of hydrographical zones were defined within the IDF on the basis of their anthropogenic and geomorphologic characteristics. Sampling effort (n = 50) was then randomly allocated according to the number of waterbodies in each group. This sampling strategy was tested in August 2006, using a field probe to estimate total phyto-plankton as well as cyanobacteria biomasses. The sampled waterbodies exhibited a wide range of phytoplankton (<1-375 mu g equiv.Chla L-1) and cyanobacteria biomasses (<1-278 mu g equiv. Chla L-1). 72% of the waterbodies in the... |

| This study investigates the micro-determinants of land use change using community, household and plot histories, an ethnographic method that constructs panel data from systematic oral recalls. A 20-year historical timeline (1975-1995) is constructed for the village of La Lima in central Honduras, based on a random sample of 97 plots. Changes in land use are examined using transition analysis and multinomial logit analysis. Transition analysis shows that land use transitions were relatively infrequent in areas under extensive cultivation, but more so in areas of intensive cultivation; and that most changes favored intensification. Econometric analysis suggests that land use intensification was influenced by plot level variables (especially altitude, slope,... |

| We use a multinominal logit model to examine the determinants of plot abandonment (unintentional fallows) and long fallows (intentional fallows) in order to propose policy interventions that lead to optimal and sustainable management of land use systems in Kigezi highlands. Household factors such as age, and post primary education positively influenced farmers' decision to abandon plots. Therefore, more fallows and abandoned terraces were common with older farmers compared to younger ones. However, farm size and household type had no significant influence on abandonment of plots. Plot variables such as slope and plot distance had the expected positive signs while soil fertility had a significant negative sign as predicted. Two types of interventions are... |

| Shortfalls in water supplies are perhaps the greatest practical NRM policy concern in Australia today, looming larger in many minds than the great international debates on greenhouse gasses, climate change and biodiversity. Because forest land cover uses more water than any other, wide expansion of upstream tree plantations can significantly reduce water yields upon which downstream urban, agricultural and wetlands depend. We consider the economic efficiency and equity (profitability and distributional) consequences of upstream land use change. The ‘environmental services’ of concern in our study are the mean annual quantities and qualities (volumes and salt concentrations) of water flowing from upper parts of a catchment to the downstream interests... |
