Novel carbon dynamics assessment framework reveals climate positive land management approaches across North America
Natural climate solutions (NCS) can foster ecosystem resiliency and mitigate climate change. However, a gap exists between carbon cycle science and decision support systems. Bridging this gap can advance climate positive land management and promote the implementation of natural climate solutions. Here, we propose a novel framework to assess carbon dynamics to reveal management approaches for land cover at a 300 m resolution within which natural c…
Sustainability of Costa Rica’s water supply under climate change scenarios
Tropical dry forest resilience and water use efficiency
Tropical dry forests (TDFs) worldwide have an environment-sensitive phenological signal, which easily marks their response to the changing climatic conditions, especially precipitation and temperature. Using TDF phenological characteristics as a proxy, this study aims to evaluate their current continental response to climate change across the Americas. Here, we show that TDFs are resilient to water stress and droughts by increasing their rain use…
Can we increase the impacts from payments for ecosystem services? Impact rose over time in Costa Rica, yet spatial variation indicates more potential
Integrating proximal broad-band vegetation indices and carbon fluxes to model gross primary productivity in a tropical dry forest
The measurement of carbon exchange between vegetation and the atmosphere is vital to quantify the impact of environmental variables on the carbon sequestration capacity of forests, and to predict how they will respond to future climate. In this study we use proximal remote sensing, defined as observations made from non-contact radiometric or imaging sensors in close proximity to the forest canopy (10–20 m), as an intermediate upscaling tool betwe…
Focus on tropical dry forest ecosystems and ecosystem services in the face of global change
Tropical dry forests are distinct from wet and moist tropical forests by the presence of a strong dry season. This collection of papers explores the unique biodiversity, plant functional traits, coupling between carbon and water cycles, and threats to these important ecosystems. These studies have relevance for conservation and management of tropical dry forests
Effect of drought on productivity in a Costa Rican tropical dry forest
Climate models predict that precipitation patterns in tropical dry forests (TDFs) will change, with an overall reduction in rainfall amount and intensification of dry intervals, leading to greater susceptibility to drought. In this paper, we explore the effect of drought on phenology and carbon dynamics of a secondary TDF located in the Santa Rosa National Park (SRNP), Costa Rica. Through the use of optical sensors and an eddy covariance flux tow…
Comparing Modis and near-surface vegetation indexes for monitoring tropical dry forest phenology along a successional gradient using optical phenology towers
Tropical dry forests (TDFs) present strong seasonal greenness signals ideal for tracking phenology and primary productivity using remote sensing techniques. The tightly synchronized relationship these ecosystems have with water availability offer a valuable natural experiment for observing the complex interactions between the atmosphere and the biosphere in the tropics. To investigate how well the MODIS vegetation indices (normalized difference v…
The Edmonton-Calgary corridor
The region connecting Edmonton and Calgary, the two largest cities in Alberta, contains rich agricultural land and is one of the most rapidly changing areas in the province. There is little legislation to restrict urban sprawl or adequately protect agricultural land or native grasslands, and there has been little research to predict future alteration. The main study objectives are, therefore, to assess historical changes in the Edmonton-Calgary c…
Biomass resilience of Neotropical secondary forests
Carbon sequestration potential of second-growth forest regeneration in the Latin American tropics
Models reveal the high carbon mitigation potential of tropical forest regeneration.
Estimation of aboveground net primary productivity in secondary tropical dry forests using the Carnegie–Ames–Stanford approach (Casa) model
Although tropical dry forests (TDFs) cover roughly 42% of all tropical ecosystems, extensive deforestation and habitat fragmentation pose important limitations for their conservation and restoration worldwide. In order to develop conservation policies for this endangered ecosystem, it is necessary to quantify their provision of ecosystems services such as carbon sequestration and primary production. In this paper we explore the potential of the C…
Measuring the effectiveness of protected area networks in reducing deforestation
Global efforts to reduce tropical deforestation rely heavily on the establishment of protected areas. Measuring the effectiveness of these areas is difficult because the amount of deforestation that would have occurred in the absence of legal protection cannot be directly observed. Conventional methods of evaluating the effectiveness of protected areas can be biased because protection is not randomly assigned and because protection can induce def…
Costa Rica's Payment for Environmental Services Program
We evaluated the intention, implementation, and impact of Costa Rica's program of payments for environmental services (PSA), which was established in the late 1990s. Payments are given to private landowners who own land in forest areas in recognition of the ecosystem services their land provides. To characterize the distribution of PSA in Costa Rica, we combined remote sensing with geographic information system databases and then used econometric…
Will buying tropical forest carbon benefit the poor? Evidence from Costa Rica

Improved Forest Cover Classification in an Industrialized Mountain Area in Japan
Space-borne satellite imagery is increasingly used for classifying and characterizing forest cover in mountain environments. Using medium resolution satellite imagery, acquired over an industrial mountain area near the city of Naeba, in the central part of Honshu, Japan, this study attempts to characterize forest cover types situated in an area affected by prolonged anthropogenic land use and land cover change (LUCC) processes. The image was topo…
Dynamics of Tropical Deforestation Around National Parks
National parks and biological reserves play an important role in counteracting the effects of tropical deforestation in mountainous environments, a leading cause of biodiversity loss worldwide. Unfortunately, information is sparse on the nature, dynamics, and spatial dimension of land use and land cover change processes that contribute to park vulnerability. This article assesses the current state of landscape fragmentation and structure on the O…
