“…Cultivated lands changed into built up areas during all the examined periods due to the population growth and the socio-economic development. A similar evolution was witnessed for other case studies in Vietnam, the Mekong Delta, or Asia [13,27,28,36,39]. A significant conversion of cultivated lands into aquaculture ponds for the entire regions on the southwest, south, and southeast of the Song Doc, the Phong Lac, the Phong Dien and the Lac An communes, which are along the Ong Doc River (an estuary connecting directly to sea) in the Tran Van Thoi District.…”

“…In many studies of coastal regions and river deltas, the area of forest sharply decreased over time because of urban development and human activities [18,19,25,29] while urban surfaces, shrublands, shrimp farms and water bodies (natural and man-made) increased at high rate [18,20,23,24,26,[30][31][32][33][34][35][36][37][38][39][40][41]. In some regions, agricultural lands significantly decreased [27,28,38,41], however, in some others, it expanded [17,23]. The study of Sakamoto et al [17] (12 provinces of the Vietnamese Mekong Delta) focused only on agriculture land with single, double and triple crops: they concluded that the available area for triple-cropped rice expanded during two years (from 2002 to 2003).…”

Abstract:The main objective of this study is to assess the spatio-temporal dynamics of land cover/land use changes in the lower Mekong Delta over the last 40 years with the coastal Tran Van Thoi District of Ca Mau Province, Vietnam as a case study. Land cover/land use change dynamics are derived from moderate to high spatial resolution (Landsat and SPOT) satellite imagery in six time intervals ranging from 1973 to 2011. Multi-temporal satellite images were collected, georeferenced, classified using per-pixel method, validated, and compared in post classification for the land use/land cover change detection in decades. Seven major land cover/land use classes were obtained, including cultivated lands, aquaculture ponds, mangrove forest, melaleuca forest, built up areas, bare lands, and natural water bodies. The accuracies of the land cover/land use maps for

Abstract. In recent years, under the background of government policy and the development of social economy, land use in hilly region of central Sichuan has changed drastically. Especially the Changzhi soil erosion control project that has been carried out since 1989 and the policy of converting from farm land to forest which has been carried out after flooding disaster in 1998, have seriously affected the land use in hilly region of central Sichuan between 1989 and 2009. In order to detect these changes and acquire the land use information, this study was conducted in Lizixi basin which is the typical area in hilly region of central Sichuan. Supervised classification was applied to the processing procedure of TM, SPOT data in 1989, 1999 and Rapideye data in 2009. The results were further improved by visual interpretation. The overall classification accuracy reaches 88.33% and the kappa is 0.8350. The elevation was classified into five grades to detect the land use distribution in different elevation gradients in 2009. Post-classification comparisons of the classified images indicated that the major change consists that the cultivated land is decreasing and forest is increasing. The force factor of these changes may be the policy of converting from farmland to forest. Because of the labor shortage, 53.29% of the decreased cultivated land has changed to abandoned arable land which is covered by lush grass and mainly distribute on the halfway up to the hill. The urban area has enlarged 7 times due to the large number of migrants from rural to urban. Overall these changes reflect the regional policies and human activities are the major and important force factors of changes in the hilly region of central Sichuan during last two decades.

“…In addition, the transformation of the catchment area surface can have an indirect impact on the formation of lowflow periods. One of the most popular methods for the catchment land cover estimation is processing remote sensing data of the Earth (Mouat and Lancaster 2008;Sheeja et al 2011). In this study, the data on land cover transformation, water withdraw, and sewage were used from the past studies (Kireeva et al 2017;State water kadastre 1990State water kadastre -2013 to analyze the direct anthropogenic impact, and the results of processing the composition of satellite images LANDSAT for the selected time periods of 1985, 1995, 2005 and 2015 were used to estimate the indirect anthropogenic impact.…”

The Don River is the largest river in the southwestern part of European Russia and the second largest river system in European Russia. The Don River basin is one of the most water deficient regions in Russia and the long term average water usage in the basin amounts to 45%. The period 2007-2016 was the longest long-term low-flow period observed, with an estimated total water resources deficit of 40.4 km 3 over 8 years. The main reason for this deficit were anomalously warm winters (2-4 degrees over average) with a low degree of soil frost penetration. This resulted in low spring flood volume (37% of the average) due to heavy seepage losses combined with thin snow cover. A similar low-flow situation was observed in 2014, when the drought caused great damage to ecosystem of Tsimlianskoye water reservoir and the River Don. Most of the fish breeding grounds had dried up by May 2014. This caused the number of round fish whitebait to drop 5-10 times below the 2002-2014 average. Inland shipping and hydropower industry also sustained losses of 42 million euro (according to interview from State Shipping company) due to low water level. This study shows that the main reasons for the 2007-2016 extreme hydrological drought are exceptional hydro-climatic conditions and anthropogenic transformations in the watershed, such as urbanisation growth and afforestation. The analysis shows that the main cause in water deficit is associated with the left tributaries of Don -Khoper and Medveditsa, while the flow in Upper Don remained more or less normal. The results can be interpreted as a "warning sign" to reduce water consumption in these sub-basins to avoid similar drought situations in future.
