Abstract

Imagery from the National Oceanic and Atmospheric Administration satellite's Advanced Very High Resolution Radiometer sensor has been used to identify an area about 100 × 400 km in Rondonia (Brazil) where massive forest clearing or deforestation is occurring. A field study verified the area of the clearing, which is associated with a large colonization program.

Periodic monitoring of such key environmental parameters as tree canopy cover, composition, and disturbance are feasible with Landsat data (Iverson et al., 1989; Westman et al., 1989; Cohen and Goward, 2004). Early approaches based on discrete land cover classification and bi-temporal change detection (Tucker et al., 1984; Skole and Tucker, 1993) evolved toward modeling of continuous vegetation structure (DeFries et al., 1998; Hansen et al., 2002a, 2002b, Cohen et al., 2003) and function (Running et al., 2004). Change detection advanced through the use of dense time-series analyses (Huang et al., 2010; Kennedy et al., 2010; Verbesselt et al., 2010; Hansen et al., 2013) and integration of directly detected changes with annual land cover information (Potapov et al., 2015; Wulder et al., 2018).
Spatially and temporally consistent vegetation structure time-series have great potential to improve the capacity for national land cover monitoring, to reduce latency and cost of international reporting, and to harmonize regional land cover characterizations. Here we present a semi-automatic, operational algorithm for mapping and monitoring of woody vegetation canopy cover and height at a regional scale using freely available Landsat time-series data. The presented algorithm employs automatic data processing and mapping using a set of lidar-based vegetation structure prediction models. Changes in vegetation cover are detected separately and integrated into the structure time-series. Sample-based validation and inter-comparison with existing datasets demonstrates the spatial and temporal consistency of our regional data time-series. The dataset reliably reflects changes in tree cover (tree cover loss user's accuracy of 0.84 and producer's accuracy of 0.75) and can serve as a tool to map annual forest extent (user's accuracy of 0.98 and producer's accuracy of 0.81 for 10% canopy cover threshold to define the forest class). The tree height estimates are consistent with a GLAS-based global map (mean average error of 3.7 m, the correlation coefficient of 0.92 and the R² of 0.85). The algorithm was prototyped within the Lower Mekong region where it revealed an intensive woody vegetation dynamic. Of the year 2000 forest area (defined using canopy cover threshold of 10% and tree height threshold of 5 m), 9.4% was deforested by the year 2017, and 16.6% was affected by stand-replacement disturbance followed by reforestation. The average annual area of stand-level forest disturbance within the region was 2.34 Mha, and increased by 34% from 2001 (1.85 Mha) to 2017 (2.48 Mha). Total forest area decreased by 6.2% within the region, and 11.1% of year 2000 primary forest area was lost by 2017. At the national level, Cambodia demonstrated the highest rate of deforestation, with a net forest area loss of 22.5%. We estimated that 21.3% of 2017 forest cover had an age of 17 years or less, illustrating the intensive forest land uses within the region. The time-series product is suitable for mapping annual land cover and inter-annual land cover change using customized class definitions. The regionally-consistent data are publicly available for download (https://glad.umd.edu/), and online analysis (https://rlcms-servir.adpc.net/en/forest-monitor/), and serve as an input to the SERVIR-Mekong Regional Land Cover Monitoring System.
Trend shifts in satellite-derived vegetation growth in Central Eurasia, 1982–2013
2017, Science of the Total Environment
Citation Excerpt :
Using remote sensing perspectives to identify land surface dynamics over long time scales is necessary to discern the spatial and temporal patterns of vegetation response to climate variability (Weiss et al., 2004). The Normalized Difference Vegetation Index (NDVI) is widely used as a robust indicator of vegetation growth as it is linked with green leaf biomass and vigor (Tucker et al., 1984). The Global Inventory Modeling and Mapping Studies (GIMMS) NDVI dataset has proven to be the most complete and longest remotely sensed measurements appropriate for long term studies of vegetation activities and climate impacts on vegetation at regional and global scales (Fensholt and Proud, 2012).
Central Eurasian vegetation is critical for the regional ecological security and the global carbon cycle. However, climatic impacts on vegetation growth in Central Eurasia are uncertain. The reason for this uncertainty lies in the fact that the response of vegetation to climate change showed nonlinearity, seasonality and differences among plant functional types. Based on remotely sensed vegetation index and in-situ meteorological data for the years 1982–2013, in conjunction with the latest land cover type product, we analyzed how vegetation growth trend varied across different seasons and evaluated vegetation response to climate variables at regional, biome and pixel scales. We found a persistent increase in the growing season NDVI over Central Eurasia during 1982–1994, whereas this greening trend has stalled since the mid-1990s in response to increased water deficit. The stalled trend in the growing season NDVI was largely attributed by summer and autumn NDVI changes. Enhanced spring vegetation growth after 2002 was caused by rapid spring warming. The response of vegetation to climatic factors varied in different seasons. Precipitation was the main climate driver for the growing season and summer vegetation growth. Changes in temperature and precipitation during winter and spring controlled the spring vegetation growth. Autumn vegetation growth was mainly dependent on the vegetation growth in summer. We found diverse responses of different vegetation types to climate drivers in Central Eurasia. Forests were more responsive to temperature than to precipitation. Grassland and desert vegetation responded more strongly to precipitation than to temperature in summer but more strongly to temperature than to precipitation in spring. In addition, the growth of desert vegetation was more dependent on winter precipitation than that of grasslands. This study has important implications for improving the performance of terrestrial ecosystem models to predict future vegetation response to climate change.
Remote Sensing and Measuring Deforestation
2016, Land Surface Remote Sensing: Environment and Risks
Forests occupy one-third of the planet’s landmass, covering nearly 4 billion hectares. The largest forested areas are located in the boreal and equatorial zones. This current distribution is not fixed, but has continuously changed over time due to the influence of environmental change and anthropogenic impact. One-third of current forested areas are made up of forest that is considered primary or intact. The remaining two-thirds are subject to anthropogenic activity and have, as a result, an uncertain future.
Boolean and fuzzy methods for identifying lateritic regoliths in the Brazilian Amazon using gamma-ray spectrometric and topographic data
2016, Geoderma
Citation Excerpt :
Therefore, the identification and discrimination of lateritic crusts is essential in mineral exploration and useful for the improvement of geological mapping. The use of the airborne gamma-ray spectrometry and altimetric data in regolith studies must be investigated, especially when applied with mathematical techniques, raster image algebra, and in the evaluation of multi-source data (e.g., Darnley and Grasty, 1971, Tucker et al., 1984, Duval, 1990, Burrough et al., 1992, Graham and Bonham-Carter, 1993, Wilford et al., 1997, Dickson and Scott, 1997, McKenzie & Ryan 1999, Zhu et al., 2010, Carrino et al., 2011, Wilford, 2012 and Dent et al., 2013). Airborne gamma-ray spectrometry measures the concentration of potassium (K) and series of uranium (U) and thorium (Th) radioisotopes in rocks and soils at depths of 30–45 cm (Gregory and Horwood, 1961; Dickson and Scott, 1997).
Airborne gamma-ray spectrometry is relatively well understood when associated with rocks, but the response and radioelement distribution in weathered materials is less known. This work used airborne gamma-ray spectrometry and altimetry to identify domains with higher probability of occurrence of lateritic crust and dismantling products in an area located in the west of the Brazilian Amazon. Map algebra was used through the Boolean and fuzzy techniques to create predictability digital models highlighting favorable areas for the occurrence of lateritic crusts. The Index Overlay Method was used in the Boolean technique. The fuzzy technique used the fuzzy algebraic product operator, fuzzy algebraic sum operator, and fuzzy gamma operator. Both models showed good correlation between the favorability predicted and the presence of crusts in the field, however, the fuzzy model showed higher correlation and highlighted areas not identified by the Boolean model. In contrast, the Boolean model allowed the visualization of the areas related to the influence of each variable or its possible combinations individually on the final map. Thus, the identification of lateritic crusts based on mathematic models applied to altimetric and airborne gamma-ray spectrometric data is a new tool that will contribute significantly to geological mapping and to the understanding related to the response and radioelement distribution in weathered materials.
Remote sensing the vulnerability of vegetation in natural terrestrial ecosystems
2014, Remote Sensing of Environment
Citation Excerpt :
Many studies have utilized Landsat and SPOT high-resolution data in concert with aerial photographs to identify logging activities by their distinctive geometry (Asner et al., 2005; Skole & Tucker, 1993). Forest degradation has been characterized empirically from Advanced Very High Resolution Radiometer (AVHRR)-derived metrics such as NDVI, leaf-area index, land cover, land- surface temperature, albedo, and productivity (Achard et al., 2002; Lambin, 1999; Tucker, Holben, & Goff, 1984) that are not always tied to physical vegetation properties (Lambin, 1999). The widely researched interactions between climate, fire, and logging have also led to several studies using remote sensing to characterize patterns of area burned and forest land use in the Amazon.
Climate change is altering the species composition, structure, and function of vegetation in natural terrestrial ecosystems. These changes can also impact the essential ecosystem goods and services derived from these ecosystems. Following disturbances, remote-sensing datasets have been used to monitor the disturbance and describe antecedent conditions as a means of understanding vulnerability to change. To a lesser extent, they have also been used to predict when desired ecosystems are vulnerable to degradation or loss. In this paper, we review studies that have applied remote sensing imagery to characterize vegetation vulnerability in both retrospective and prospective modes. We first review vulnerability research in natural terrestrial ecosystems including temperate forests, tropical forests, boreal forests, semi-arid lands, coastal areas, and the arctic. We then evaluate whether remote sensing can evaluate vulnerability sufficiently in advance of future events in order to allow the implementation of mitigation strategies, or whether it can only describe antecedent conditions a posteriori. The majority of existing research has evaluated vulnerability retrospectively, but key studies highlight the considerable potential for the development of early warnings of future vulnerability. We conclude that future research needs to focus on the development of a greater number of remotely sensed metrics to be used in a prospective mode in assessing vulnerability of terrestrial vegetation under change.

Responding to users' needs, ESA's Living Planet Programme [20] comprises a science and research element [21,22], which includes the Earth Explorer missions (with missions such as GOCE, SMOS, CRYOSAT and SWARM) and an ‘Earth Watch’ element, designed to facilitate the delivery of Earth observation data for use in operational services. Earth Watch includes the well-established meteorological missions developed with Eumetsat [23,24]. The space component of GMES is composed of satellite missions called Sentinels, specifically developed by ESA for the needs of GMES, and of “GMES Contributing Missions”, owned or operated by European national or multinational organizations that are already providing data to GMES.
Satellite remote sensing technology has contributed to the transformation of multiple earth science domains, putting space observations at the forefront of innovation in earth science. With new satellite missions being launched every year, new types of earth science data are being incorporated into science models and decision-making systems in a broad array of organizations. Policy guidance can influence the degree to which user needs influence mission design and when, and ensure that satellite missions serve both the scientific and user communities without becoming unfocused and overly expensive. By considering the needs of the user community early on in the mission-design process, agencies can ensure that satellites meet the needs of multiple constituencies. This paper describes the mission development process in NASA and ESA and compares and contrasts the successes and challenges faced by these agencies as they try to balance science and applications within their missions.
