Commodity crop expansion, for both global and domestic urban markets, follows multiple land change pathways entailing direct indirect deforestation, results in various social environmental impacts. Here we compare six published case studies of rapid commodity expansion within forested tropical regions. Across cases, between 1.7% 89.5% new cropland was sourced from forestlands. Four main factors controlled expansion: (i) the availability suitable forestland, which is determined by forest...
Abstract High-yield agriculture potentially reduces pressure on forests by requiring less land to increase production. Using satellite and field data, we assessed the area deforested industrial-scale high-yield oil palm expansion in Peruvian Amazon from 2000 2010, finding that 72% of new plantations expanded into forested areas. In a focus Ucayali region, deforestation for high- smallholder low-yield plantations. Low-yield accounted most overall (80%), but only 30% their involved forest...
Abstract. Understanding Earth system dynamics in light of ongoing human intervention and dependency remains a major scientific challenge. The unprecedented availability data streams describing different facets the now offers fundamentally new avenues to address this quest. However, several practical hurdles, especially lack interoperability, limit joint potential these streams. Today, many initiatives within beyond sciences are exploring approaches overcome hurdles meet growing...
In Indonesia, drought driven fires occur typically during the warm phase of El Niño Southern Oscillation. This was case events 1997 and 2015 that resulted in months-long hazardous atmospheric pollution levels Equatorial Asia record greenhouse gas emissions.
After more than 50-years of armed conflict, Colombia is now transitioning to a stable social and political climate due series peace agreements between the government different groups. Consequences these socio-economic changes on ecosystems are largely uncertain, but there growing concern about derived increases in environmental degradation. Here, we review capacity monitor state its their rate change over time. We found several important programs currently set place by institutions as well...
Peru has the fourth largest area of peatlands in Tropics. Its most representative land cover on peat is a Mauritia flexuosa dominated palm swamp (thereafter called dense PS), which been under human pressure over decades due to high demand for M. fruit often collected by cutting down entire palm. Degradation these carbon forests can substantially affect emissions greenhouse gases and contribute climate change. The first objective this research was assess impact PS degradation forest structure...
Destructive fires in Amazonia have occurred the past decade, leading to forest degradation, carbon emissions, impaired air quality, and property damage. Here, we couple climate, geospatial, province-level census data, with farmer surveys examine climatic, demographic, land use factors associated fire frequency Peruvian Amazon from 2000 2010. Although our results corroborate previous findings elsewhere that drought proximity roads increase frequency, province-scale analysis further identifies...
Fire is becoming a pervasive driver of environmental change in Amazonia and expected to intensify, given projected reductions precipitation forest cover. Understanding the influence post-deforestation land cover on fires limited, even though cleared lands constitute threat for ecosystems, agriculture, human health. We used MODIS satellite data map burned areas annually between 2001 2010. then combined these maps with climate information understand dry-season severity fire occurrence spread...
Abstract Tropical second‐growth forests could help mitigate climate change, but the degree to which their carbon potential is achieved will depend on exposure disturbance. Wind disturbance common in tropical forests, shaping structure, composition, and function, influencing successional trajectories. However, little known about impacts of extreme winds fragmented landscapes, though these ecosystems are often located mosaics forest, pasture, cropland, other land cover types. Indirect evidence...
Many countries have made major commitments to carbon sequestration through reforestation under the Paris Climate Agreement, and recent studies illustrated potential for large amounts of in tropical second-growth forests. However, gains forests are threatened by non-permanence, i.e. release into atmosphere from clearing or disturbance. The benefits require long-term persistence on landscape, but estimates rarely consider spatio-temporal landscape dynamics In this study, we used remotely...
Abstract Infrastructure systems have direct implications for how health and well-being evolve across urban–rural systems. Scientists, practitioners, policy-makers use domain-specific methods tools to characterize sectors of infrastructure, but these approaches do not capture the cascading effects interrelated infrastructure governance domains. We argue that development management sustainable urban must focus on interactions rural places advance equitable well-being. call a research agenda...
Abstract A well-documented environmental threat in the Amazonian region of Loreto, Peru involves harvesting fruit from dominant palm Mauritia flexuosa by chopping fruit-bearing females growing carbon-dense peat swamps. Numerous conservation interventions have been proposed to protect swamps, such as encouraging harvest fruits climbing palms preserve resource instead cutting them. These efforts produced mixed success; some communities embraced sustainable methods, while others not, despite...
Aedes albopictus is a viable vector for several infectious diseases such as Zika, West Nile, Dengue viruses and others. Originating from Asia, this invasive species rapidly expanding into North American temperate areas urbanized places causing major concerns public health. Previous analyses show that warm temperatures high humidity during the mosquito season are ideal conditions A. development, while its distribution correlated with population density. To better understand expansion urban it...
Tropical forests are disappearing at unprecedented rates, but the drivers behind this transformation not always clear. This limits decision-making processes and effectiveness of forest management policies. In paper, we address extent deforestation Choco biodiversity hotspot, which has received much scientific attention despite its high levels plant diversity endemism. The climate is characterized by persistent cloud cover a challenge for land mapping from optical satellite imagery. By using...

The vast peat deposits in the Peruvian Amazon are crucial to global climate. Palm swamp, most extensive regional peatland ecosystem faces different threats, including deforestation and degradation due felling of dominant palm Mauritia flexuosa for fruit harvesting. While these activities convert this natural C sink into a source, distribution related emissions remain unstudied. We used remote sensing data from Landsat, ALOS-PALSAR, NASA's GEDI spaceborne LiDAR-derived products map swamp...
SUMMARY The implementation of an international programme for reducing carbon emissions from deforestation and degradation (REDD) can help to mitigate climate change bring numerous benefits environmental conservation. Information on land modelling mapping contribute quantify future deforestation. However limitations in data availability technical capabilities may constitute obstacle countries interested participating the REDD programme. This paper evaluates influence quantity allocation...
