Remote sensing monitoring of land restoration interventions in semi-arid environments with a before–after control-impact statistical design

  
International Journal of Applied Earth Observation and Geoinformation, Vol. 59 (July 2017), pp. 42-52, https://doi.org/10.1016/j.jag.2017.02.016

Abstract

[Highlights] [::] A rapid, standardised and objective assessment of the biophysical impact of restoration interventions is proposed. [::] The intervention impact is evaluated by a before–after control-impact sampling design. [::] The method provides a statistical test of the no-change hypothesis and the estimation of the relative magnitude of the change. [::] The method is applicable to NDVI and other remote sensing-derived variables. [Abstract] Restoration interventions to combat land degradation are carried out in arid and semi-arid areas to improve vegetation cover and land productivity. Evaluating the success ...

 

Evaluation of optical remote sensing to estimate actual evapotranspiration and canopy conductance

  
Remote Sensing of Environment, Vol. 129 (February 2013), pp. 250-261, https://doi.org/10.1016/j.rse.2012.11.004

Abstract

[Abstract] We compared estimates of actual evapotranspiration (ET) produced with six different vegetation measures derived from the MODerate resolution Imaging Spectroradiometer (MODIS) and three contrasting estimation approaches using measurements from eddy covariance flux towers at 16 FLUXNET sites located over six different land cover types. The aim was to assess optimal approaches in using optical remote sensing to estimate ET. The first two approaches directly regressed various MODIS vegetation indices (VIs) and products such as leaf area index (LAI) and fraction of ...

Abstract

In this paper, we present an automated classification method of landform elements using an application of SAGA GIS software. The spatial assessment was done on the Yambaru forest area (YFA) in the northernmost part of Okinawa Island, Japan. This task is performed through the detailed elevation grid analyses from DTM of YFA with a spatial scale of 10 × 10 m2 supported by The Geospatial Information Authority of Japan. The classification has ten classes; high ridges, midslope ridges, upland drainage, upper ...

 

Changes and status of mangrove habitat in Ganges delta: case study in Indian part of Sundarbans

  
International Journal of Geology, Earth & Environmental Sciences, Vol. 4, No. 3. (2014), pp. 109-118

Abstract

This paper quantifies the changes and present status of mangrove forest in Indian part of Sundarban from 1975 to 2014 using Landsat MSS (1975), TM (1990), ETM (2002) and OLM (2014) satellite imageries. The study used two image processing techniques: Maximum Likelihood Classification for the Land use and land cover analysis and NDVI for the vegetation characteristics and their temporal changes. The research found that the area of mangrove gradually decreases from 203752 hector (44%) to 132723 hector (31 %) and the barren land increases from ...

A MODIS-based global 1-km maximum green vegetation fraction dataset

  
Journal of Applied Meteorology and Climatology, Vol. 53, No. 8. (21 May 2014), pp. 1996-2004, https://doi.org/10.1175/jamc-d-13-0356.1

Abstract

Global land-cover data are widely used in regional and global models because land cover influences land–atmosphere exchanges of water, energy, momentum, and carbon. Many models use data of maximum green vegetation fraction (MGVF) to describe vegetation abundance. MGVF products have been created in the past using different methods, but their validation with ground sites is difficult. Furthermore, uncertainty is introduced because many products use a single year of satellite data. In this study, a global 1-km MGVF product is developed on ...

Timing of erosion and satellite data: a multi-resolution approach to soil erosion risk mapping

  
International Journal of Applied Earth Observation and Geoinformation, Vol. 10, No. 3. (September 2008), pp. 267-281, https://doi.org/10.1016/j.jag.2007.10.009

Abstract

Erosion reduces soil productivity and causes negative downstream impacts. Erosion processes occur on areas with erodible soils and sloping terrain when high-intensity rainfall coincides with limited vegetation cover. Timing of erosion events has implications on the selection of satellite imagery, used to describe spatial patterns of protective vegetation cover. This study proposes a method for erosion risk mapping with multi-temporal and multi-resolution satellite data. The specific objectives of the study are: (1) to determine when during the year erosion risk is ...

 

Regional vegetation die-off in response to global-change-type drought

  
Proceedings of the National Academy of Sciences, Vol. 102, No. 42. (10 October 2005), pp. 15144-15148, https://doi.org/10.1073/pnas.0505734102

Abstract

Future drought is projected to occur under warmer temperature conditions as climate change progresses, referred to here as global-change-type drought, yet quantitative assessments of the triggers and potential extent of drought-induced vegetation die-off remain pivotal uncertainties in assessing climate-change impacts. Of particular concern is regional-scale mortality of overstory trees, which rapidly alters ecosystem type, associated ecosystem properties, and land surface conditions for decades. Here, we quantify regional-scale vegetation die-off across southwestern North American woodlands in 2002-2003 in response to drought and ...

Global Change Biology, Vol. 16, No. 9. (March 2010), pp. 2504-2517, https://doi.org/10.1111/j.1365-2486.2010.02189.x

Abstract

This research aims at developing a remote sensing technique for monitoring the interannual variability of the European larch phenological cycle in the Alpine region of Aosta Valley (Northern Italy) and to evaluate its relationships with climatic factors. Phenological field observations were conducted in eight test sites from 2005 to 2007 to determine the dates of completion of different phenological phases. MODerate Resolution Imaging Spectrometer (MODIS) 250 m 16-days normalized difference vegetation index (NDVI) time series were fitted with double logistic curves and ...

 

Phenological monitoring of grassland and larch in the Alps from Terra and Aqua MODIS images

  
Italian Journal of Remote Sensing, Vol. 43 (31 October 2011), pp. 83-96, https://doi.org/10.5721/itjrs20114336

Abstract

This study compares MODIS NDVI 16-day (250 m) time series, acquired by Terra and Aqua platforms, for monitoring the phenological cycle of larch and grasslands in an alpine environment. The accuracy of MODIS 250 m Terra and Aqua phenological metrics was evaluated for larch forests through comparison with field data. At regional level it was carried out a correlation analysis between the mean dates of start and end of season detected from MODIS Terra and Aqua in different years. Regional maps ...

 

On the relationship between FAPAR and NDVI

  
Remote Sensing of Environment, Vol. 49, No. 3. (September 1994), pp. 200-211, https://doi.org/10.1016/0034-4257(94)90016-7
Keywords: fapar   ndvi   remote-sensing  

Abstract

The influence of pixel heterogeneity, background, atmospheric and bidirectional effects on the relationship between fraction of photosynthetically active radiation absorbed by the photosynthesizing tissue in a canopy (FAPAR) and normalized difference vegetation index (NDVI) is investigated using a three-dimensional model of radiation transfer. Top of the canopy (TOC) NDVI and FAPAR increase with ground cover and plant leaf area. Their functional response to leaf orientation, solar zenith angle and atmospheric optical depth is similar. For instance, planophile canopies (mostly horizontal leaves) ...

 

Quantifying and mapping biodiversity and ecosystem services: Utility of a multi-season NDVI based Mahalanobis distance surrogate

  
Remote Sensing of Environment, Vol. 113, No. 4. (15 April 2009), pp. 857-867, https://doi.org/10.1016/j.rse.2008.12.011

Abstract

There is an urgent need for techniques to rapidly and periodically measure biodiversity and ecosystem services over large landscapes. Conventional vegetation classification and mapping approaches are based on discrete arbitrary classes which do not capture gradual changes in forest type (and corresponding biodiversity and ecosystem services values) from site to site. We developed a simple multi-date NDVI based Mahalanobis distance measure (called eco-climatic distance) that quantifies forest type variability across a moisture gradient for complex tropical forested landscapes on a single ...
