| ABSTRACT This paper examines changes over time for a full generation of migrant settlers in the Northern Ecuadorian Amazon (NEA). Data were collected from a 2014 household survey covering a subsample of households surveyed previously in 1990 and 1999. We observed changes in demographic behavior, land use, forest cover, and living conditions. As the frontier develops, human fertility is continuing to decline with contraceptive prevalence rising. Meanwhile, out-migration from colonist households, largely to destinations within the region, persists. More households have secure land tenure than in 1999, and are better off as measured by possession of assets. There is continued growth in pasture, largely at the expense of forest. Farms still serve as an... |

| This paper examines the success of small-scale farming livelihoods in adapting to climate variability and change. We represent adaptation actions as choices within a response space that includes coping but also longer-term adaptation actions, and define success as those actions which promote system resilience, promote legitimate institutional change, and hence generate and sustain collective action. We explore data on social responses from four regions across South Africa and Mozambique facing a variety of climate risks. The analysis suggests that some collective adaptation actions enhance livelihood resilience to climate change and variability but others have negative spillover effects to other scales. Any assessment of successful adaptation is, however,... |

| The severe tensions between conservation and development are illustrated by events in Malinau Dstrict (Kalimantan, Indonesia). Conservationists decry proposed plans for logging and conversion of pristine tropical forest to oil palm (Elaeis guineensis). Although the local government is willing to declare the district a “conservation district,” at the same time, it shows interest in oil palm conversion. This article explores the impact of the potential conversion of 500 000 ha of forest to oil palm on forest cover, in-migration, and the local economy in Malinau. The simulation model was developed using STELLA® software, and relies on a combination of empirical data, data from the literature, and stakeholder perceptions.... |

| The literature on drought, livelihoods, and poverty suggests that dryland residents are especially vulnerable to climate change. However, assessing this vulnerability and sharing lessons between dryland communities on how to reduce vulnerability has proven difficult because of multiple definitions of vulnerability, complexities in quantification, and the temporal and spatial variability inherent in dryland agroecological systems. In this closing editorial, we review how we have addressed these challenges through a series of structured, multiscale, and interdisciplinary vulnerability assessment case studies from drylands in West Africa, southern Africa, Mediterranean Europe, Asia, and Latin America. These case studies adopt a common vulnerability framework... |

| Given that few studies have valued the provisioning services of temperate southern African wetlands, research on this topic was undertaken in a remote rural wetland, Letseng-la-Letsie, in Lesotho and a peri-urban wetland in Mfuleni, Cape Town. The objectives were to quantify incomes from wetland resources, assess the relative dependency of communities on wetland provisioning services, and estimate the total provisioning value of the wetlands. Data were collected from informal interviews and structured household surveys. Despite the different settings, both wetlands were used mainly for grazing livestock. The estimated total value added during 2007 from grazing was U.S. $180,078 for Letseng-la-Letsie and U.S. $540,286 for Mfuleni. Letseng-la-Letsie and... |

| The landscape of Mengsong, southwest China, was biologically diverse until recently due to historical biogeographical processes overlain by the swidden-cultivation practices of the Hani who migrated there several centuries ago. Our research sought to understand how the Hani adjusted their livelihoods to new policies, markets, and technologies, and the consequences for biodiversity conservation. We combined landscape, plot, and household surveys, interviews, and reviews of secondary documents, to reconstruct the major changes and responses to challenges in the social–ecological system over previous decades. Significant changes from closed to open canopy of secondary-forest vegetation took place between 1965–1993 and from open-canopy... |

| Assessing the performance of management is central to natural resource management, in terms of improving the efficiency of interventions in an adaptive-learning cycle. This is not simple, given that such systems generally have multiple scales of interaction and response; high frequency of nonlinearity, uncertainty, and time lags; multiple stakeholders with contrasting objectives; and a high degree of context specificity. The importance of bounding the problem and preparing a conceptual model of the system is highlighted. We suggest that the capital assets approach to livelihoods may be an appropriate organizing principle for the selection of indicators of system performance. In this approach, five capital assets are recognized: physical, financial, social,... |

| Effective conservation depends largely on people’s compliance with regulations. We investigate compliance through the lens of fishers’ compliance with marine protected areas (MPAs). MPAs are widely used tools for marine conservation and fisheries management. Studies show that compliance alone is a strong predictor of fish biomass within MPAs. Hence, fishers’ compliance is critical for MPA effectiveness. However, there are few empirical studies showing what factors influence fishers’ compliance with MPAs. Without such information, conservation planners and managers have limited opportunities to provide effective interventions. By studying 12 MPAs in a developing country (Costa Rica), we demonstrate the role that... |

| Aquatic agricultural systems in developing countries face increasing competition from multiple stakeholders over rights to access and use natural resources, land, water, wetlands, and fisheries, essential to rural livelihoods. A key implication is the need to strengthen governance to enable equitable decision making amidst competition that spans sectors and scales, building capacities for resilience, and for transformations in institutions that perpetuate poverty. In this paper we provide a simple framework to analyze the governance context for aquatic agricultural system development focused on three dimensions: stakeholder representation, distribution of power, and mechanisms of accountability. Case studies from Cambodia, Bangladesh, Malawi/Mozambique,... |

| Change is a defining characteristic of coastal social-ecological systems, yet the magnitude and speed of contemporary change is challenging the adaptive capacity of even the most robust coastal communities. In the context of multiple drivers of change, it has become increasingly important to identify how threatened communities adapt to livelihood stressors. We investigate how adaptation is negotiated in two coastal fishing communities by documenting livelihood stressors, household assets, adaptive strategies, and factors that facilitate or inhibit adaptation. Declining catch is the most common stressor being experienced in both communities, however, socioeconomic, e.g., disease or theft, and ecological, e.g., severe storms and drought, changes are also... |
