In Latin America, the cultivation of Arabica coffee (Coffea arabica) plays a critical role in rural livelihoods, biodiversity conservation, and sustainable development. Over the last 20 years, coffee farms and landscapes across the region have undergone rapid and profound biophysical changes in response to low coffee prices, changing climatic condi...

Full-text available
As tropical regions are converted to agriculture, conservation of biodiversity will depend not only on the maintenance of protected forest areas, but also on the scope for conservation within the agricultural matrix in which they are embedded. Tree cover typically retained in agricultural landscapes in the neotropics may provide resources and habit...

Climate change is driving severe outbreaks of crop diseases, decimating agricultural production, and disrupting rural livelihoods globally. While the patterns of agricultural disease outbreaks are well documented, less is known about the extent to which climate change-driven diseases are affecting crop production, disrupting farmer livelihoods, and...

Climate change is increasingly driving fundamental shifts in ecosystems, land use, and human livelihoods. Because of these rapid shifts, some conventional adaptation strategies may have limited success in reducing the impact of climate change. In some circumstances, there will be a need for considering transformative changes as part of adaptation s...

Ecosystem-based adaptation (EbA) is the use of biodiversity and ecosystem services as part of a strategy to help people adapt to climate change. Despite the potential of EbA to provide adaptation benefits, there is a lack of consensus on how to measure the success of this approach. This paper reviews the intended adaptation outcomes and indicators...

Sustainability agendas increasingly recognize that attaining conservation and development outcomes demands greater integration across sectors. Integrated landscape initiatives (ILIs) are a leading approach to reconciling multiple objectives. However, a characterization of the diversity of approaches under the ILI umbrella and the comparative perfor...
Article
Full-text available
In the face of major shifts in temperature and precipitation, some conventional strategies that help people to cope or incrementally adapt to climate change may become inappropriate in the long-term. Transformative adaptation, i.e. fundamental systems' changes that address root causes of vulnerability may be needed. However, we have a limited under...

Despite the Amazon’s natural wealth, food insecurity is a major concern among indigenous communities. Yet, little is known about the socio-ecological dynamics shaping the contributions of local ecosystems to food security. In this study we examine how ecological features interact with normative structures, lifestyles, and livelihoods to expose indi...
Article
Full-text available
Although it has been hypothesized that men and women vary in the way they value ecosystem services, research on ecosystem services rarely incorporates a gender dimension. We conducted research with nine indigenous communities in the Colombian Amazon to understand which ecosystem services men and women perceive as most important for their wellbeing...

Despite global recognition of the social, economic and ecological impacts of deforestation, the world is losing forests at an alarming rate. Global and regional efforts by policymakers and donors to reduce deforestation need science-driven information on where forest loss is happening, and where it may happen in the future. We used spatially-explic...

Forest conservation and REDD+ projects invest millions of dollars each year to reduce local communities’ dependence on forests and prevent forest loss and degradation. However, to date, there is limited evidence on whether these investments are effective at delivering conservation outcomes. We explored the relationships between 600+ small-scale con...
Data
Summary statistics before and after log-transformation of dependent and treatment variables. We use a fixed effects linear panel model (Eq 1) to estimate the relationship between conservation investments and conservation outcomes. The underlying data had high skewness and were log-transformed. This greatly reduced the skewness of the data. (DOCX)
Data

Data
Relationships between investments and deforestation. A polynomial graph of the relationship between log-transformed dollars invested and log-transformed percent deforestation suggested a linear relationship. Thus, a linear relationship was estimated in Eq 1. Points represent underlying data and dashed line is fitted relationship. (DOCX)
Data
Relationships between investments and fires. A polynomial graph of the relationship between log-transformed dollars invested and log-transformed number of fire detections suggested a linear relationship.

Climate change will cause geographic range shifts for pollinators and major crops, with global implications for food security and rural livelihoods. However, little is known about the potential for coupled impacts of climate change on pollinators and crops. Coffee production exemplifies this issue, because large losses in areas suitable for coffee...
