“…As noted by previous authors (De Rose et al 2011), vegetation recovery also depends on terrain morphology, geology and watershed morphology: as topography and water availability are characterized by large gradients in the study area, it can be expected that ash thickness will only be one factor controlling the recovery rate. Notwithstanding these limitations, the link between ash thickness and vegetation recovery enables to further constrain the variation in thickness of the ash layer around OL.…”

“…Wilson et al (2011) noted that in Argentina, 10 cm of ash was sufficient to totally bury winter pastures, but that vegetation could survive or quickly re-establish through an ash layer of <7 cm -or even <12 cm were there was no water shortage. Water and wind help vegetation recovery by stimulating erosion (Wilson et al 2011;De Rose et al 2011). Anderson et al (2012) similarly highlighted the role of rainfall amount in controlling the germination of seeds after fires in the Serengeti region.…”

“…Vegetation types, ash thickness, rainfall, erosion pattern and rate, and human influence were identified as important factors controlling vegetation recovery (Frenzen 1992;Harrington et al 1998;del Moral and Grishin 1999;Marzen et al 2011). De Rose et al (2011 further concluded that watershed topography and geology have an important impact on the trajectory and the speed of vegetation recovery.…”

“…Only De Rose et al (2011) and Marzen et al (2011) used vegetation indices derived from remote sensing data to analyse vegetation recovery at volcanoes. Marzen et al (2011) monitored vegetation recovery from 1980 to 2005 at Mt St Helens using bi-temporal difference analysis of NDVILandsat images.…”

Ash fall impact on vegetation: a remote sensing approach of the Oldoinyo Lengai 2007–08 eruption

Impacts from ash fallout on the environment can be widespread and long lasting, even from moderate-size eruptions. Assessing ash impact on vegetation and the indirect impacts for people is often difficult in the field. Here it is assessed how satellite data can help to map vegetation affected by ash and how temporal analysis enables characterization of vegetation recovery rate. . The spatial pattern of the ash-affected area matches with the spatial contrast in the impact experienced by the local communities. The method applied here opens the scope to document impact and intensity of ash fallout in areas where systematic field work is not possible and to support recovery plans for populations affected by ash fallout.

“…As for urbanization, it is essential to derive land-use/cover maps from remote-sensing imageries (Antrop, 2007;Radoux et al, 2016). In recent years, the Landsat and Aster imageries are often used for mapping land-use/cover and (Coulter et al, 2016;De Rose, Oguchi, Morishima, & Collado, 2011;Garcia et al, 2008;Satir & Erdogan, 2016;Schmugge, Kustas, & Humes, 1998). Meanwhile, some researches focused on modelling the urban sprawl and its environment impact (Kurucu & Chiristina, 2008;Nole, Murgante, Calamita, Lanorte, & Lasaponara, 2015), and stimulating the heat island phenomenon (Kato & Yamaguchi, 2005;Liu & Zhang, 2011).…”

Urbanization in China has been rapid over the past three decades causing substantial replacement of the natural landscape by built-up land. In this paper, we present a comparison of Sentinel-2A MSI (S2A) and Landsat-8 OLI (L8) data in the retrieval of five built-up indices, namely Urban Index (UI), Normalized Difference Built-up Index (NDBI), Index-based Built-up Index (IBI) and two visible based indices, i.e. VgNIR-BI and VrNIR-BI. All the built-up indices maps water-masked were classified into built-up and non-built-up land using Otsu's method. Simultaneously, the support vector machine (SVM) algorithm was employed to classify the two imageries into three respective classes. The accuracy assessment results show that all built-up indices had higher Overall Accuracy for S2A (up to 98.14% for VrNIR-BI) and L8 (up to 98.42% for VrNIR-BI) imageries compared to SVM. The percentage differences demonstrate that L8 estimates higher built-up area compared to S2A between 1.48% and 8.45% via the built-up indices and 13.40% compared to the SVM. Cross-checking with the Statistical Yearbook, S2A is superior to L8 in built-up land mapping capability, especially utilizing built-up indices. The difference caused by spatial resolution and spectral response functions should be taken into consideration in synergistic scientific application.
