  • The connection between forest degradation and urban energy demand in sub-Saharan Africa

    Open AccessF Sedano, Sá Nogueira Lisboa et al.ARTICLEEnvironmental Research Letters2021

    Charcoal is a key energy source for urban households in sub-Saharan Africa and charcoal production is the main cause of forest degradation across the region. We used multitemporal high-resolution remote sensing optical imagery to quantify the extent and intensity of forest degradation associated with charcoal production and its impact on forest carbon stocks for the main supplying area of an African capital. This analysis documents the advance of…

  • Climate drivers of Arctic tundra variability and change using an indicators framework

    Open AccessUma S Bhatt, Donald A Walker et al.ARTICLEEnvironmental Research Letters2021

    This study applies an indicators framework to investigate climate drivers of tundra vegetation trends and variability over the 1982–2019 period. Previously known indicators relevant for tundra productivity (summer warmth index (SWI), coastal spring sea-ice (SI) area, coastal summer open-water (OW)) and three additional indicators (continentality, summer precipitation, and the Arctic Dipole (AD): second mode of sea level pressure variability) are …

  • Monitoring forest degradation from charcoal production with historical Landsat imagery. A case study in southern Mozambique

    Open AccessF Sedano, Sá Nogueira Lisboa et al.ARTICLEEnvironmental Research Letters2019

    We used historical Landsat imagery to monitor forest degradation from charcoal production in the main supplying region of the Mozambican capital, Maputo, during a ten-year period (2008–2018). We applied a change detection method that exploits temporal NDVI dynamics associated with charcoal production. This forest degradation temporal sequence exposes the magnitude and the spatial and temporal dynamics of charcoal production, which is the main for…

  • Changing seasonality of panarctic tundra vegetation in relationship to climatic variables

    Open AccessUma S Bhatt, Donald A Walker et al.ARTICLEEnvironmental Research Letters2017

    Potential climate drivers of Arctic tundra vegetation productivity are investigated to understand recent greening and browning trends documented by maximum normalized difference vegetation index (NDVI) (MaxNDVI) and time-integrated NDVI (TI-NDVI) for 1982–2015. Over this period, summer sea ice has continued to decline while oceanic heat content has increased. The increases in summer warmth index (SWI) and NDVI have not been uniform over the satel…

  • The impact of charcoal production on forest degradation

    Open AccessF Sedano, Jully Anne da Silva et al.ARTICLEEnvironmental Research Letters2016

    Charcoal production for urban energy consumption is a main driver of forest degradation in sub Saharan Africa. Urban growth projections for the continent suggest that the relevance of this process will increase in the coming decades. Forest degradation associated to charcoal production is difficult to monitor and commonly overlooked and underrepresented in forest cover change and carbon emission estimates. We use a multitemporal dataset of very h…

  • Dynamics of aboveground phytomass of the circumpolar Arctic tundra during the past three decades

    Open AccessHoward E Epstein, Martha K Raynolds et al.ARTICLEEnvironmental Research Letters2012

    Numerous studies have evaluated the dynamics of Arctic tundra vegetation throughout the past few decades, using remotely sensed proxies of vegetation, such as the normalized difference vegetation index (NDVI). While extremely useful, these coarse-scale satellite-derived measurements give us minimal information with regard to how these changes are being expressed on the ground, in terms of tundra structure and function. In this analysis, we used a…

  • Recent change of vegetation growth trend in China

    Open AccessShushi Peng, Anping Chen et al.ARTICLEEnvironmental Research Letters2011

    Using satellite-derived normalized difference vegetation index (NDVI) data, several previous studies have indicated that vegetation growth significantly increased in most areas of China during the period 1982–99. In this letter, we extended the study period to 2010. We found that at the national scale the growing season (April–October) NDVI significantly increased by 0.0007 yr −1 from 1982 to 2010, but the increasing trend in NDVI over the last d…

  • Circumpolar Arctic Tundra Vegetation Change Is Linked to Sea Ice Decline

    Uma S Bhatt, Donald A Walker et al.ARTICLEEarth Interactions2010

    Linkages between diminishing Arctic sea ice and changes in Arctic terrestrial ecosystems have not been previously demonstrated. Here, the authors use a newly available Arctic Normalized Difference Vegetation Index (NDVI) dataset (a measure of vegetation photosynthetic capacity) to document coherent temporal relationships between near-coastal sea ice, summer tundra land surface temperatures, and vegetation productivity. The authors find that, duri…

  • Fifty years of deforestation and forest fragmentation in Madagascar

    Open AccessGrady Harper, GRADY J HARPER et al.ARTICLEEnvironmental Conservation2007

    Tropical deforestation is a key contributor to species extinction and climate change, yet the extent of tropical forests and their rate of destruction and degradation through fragmentation remain poorly known. Madagascar's forests are among the most biologically rich and unique in the world but, in spite of longstanding concern about their destruction, past estimates of forest cover and deforestation have varied widely. Analysis of aerial photogr…

  • Thirty Years of Land-cover Change in Bolivia

    Timothy J Killeen, Veronica Calderon et al.ARTICLEAMBIO2007Citada por: 8

    Land-cover change in eastern lowland Bolivia was documented using Landsat images from five epochs for all landscapes situated below the montane tree line at approximately 3000 m, including humid forest, inundated forest, seasonally dry forest, and cloud forest, as well as scrublands and grasslands. Deforestation in eastern Bolivia in 2004 covered 45,411 km2, representing approximately 9% of the original forest cover, with an additional conversion…

  • Evidence for a significant urbanization effect on climate in China

    Open AccessLiming Zhou, Lynn Gelzheiser et al.ARTICLEProceedings of the National…2004

    China has experienced rapid urbanization and dramatic economic growth since its reform process started in late 1978. In this article, we present evidence for a significant urbanization effect on climate based on analysis of impacts of land-use changes on surface temperature in southeast China, where rapid urbanization has occurred. Our estimated warming of mean surface temperature of 0.05°C per decade attributable to urbanization is much larger t…

  • Climate-Driven Increases in Global Terrestrial Net Primary Production from 1982 to 1999

    Open AccessRamakrishna Nemani, Ramakrishna R Nemani et al.ARTICLEScience2003

    Recent climatic changes have enhanced plant growth in northern mid-latitudes and high latitudes. However, a comprehensive analysis of the impact of global climatic changes on vegetation productivity has not before been expressed in the context of variable limiting factors to plant growth. We present a global investigation of vegetation responses to climatic changes by analyzing 18 years (1982 to 1999) of both climatic data and satellite observati…

  • Variations in northern vegetation activity inferred from satellite data of vegetation index during 1981 to 1999

    Open AccessLiming Zhou, Lynn Gelzheiser et al.ARTICLEJournal of Geophysical Research:…2001

    The northern high latitudes have warmed by about 0.8°C since the early 1970s, but not all areas have warmed uniformly [ Hansen et al ., 1999]. There is warming in most of Eurasia, but the warming rate in the United States is smaller than in most of the world, and a slight cooling is observed in the eastern United States over the past 50 years. These changes beg the question, can we detect the biotic response to temperature changes? Here we presen…

  • Climate-disease connections

    Open AccessAssaf Anyamba, Kenneth J Linthicum et al.ARTICLECadernos de Saude Publica2001Citada por: 4Referências: 19

    All known Rift Valley fever(RVF) outbreaks in Kenya from 1950 to 1998 followed periods of abnormally high rainfall. On an interannual scale, periods of above normal rainfall in East Africa are associated with the warm phase of the El Niño/Southern Oscillation (ENSO) phenomenon. Anomalous rainfall floods mosquito-breeding habitats called dambos, which contain transovarially infected mosquito eggs. The eggs hatch Aedes mosquitoes that transmit the …
