Land use land cover (LULC) change analysis emerged as one of the most significant factors which assist decision makers to ensure sustainable development and to understand the dynamics of our changing environment. An integrated approach of remote sensing and GIS has been used to study the land use land cover dynamics of the Western Doon Valley, Uttarakhand. Landsat satellite imageries of two different time periods, i.e., Landsat ETM + data of 2001 and 2010 were acquired and used to quantify the land use land cover changes in the study area from 2001 to 2010 over a period of one decade. ERDAS Imagine 10 software has been used to carry out the supervised classification using a maximum likelihood technique. The images of the study area were categorized into five different classes, viz., agricultural land area, settlement area, forest cover area, wasteland area, and water body area. The result indicates that during the decadal period, the agriculture forest and settlement area have increased about 6.22% (i.e., 25.19 km²), 0.30% (i.e., 2.66 km²), 2.17% (20.47 km²), respectively, while area under other land categories such as wasteland and water bodies have decreased about 6.16% (i.e., 22.67 km²) and 2.52% (i.e., 0.22 km²), respectively.

to quantify the land use land cover changes in the study area from 2001 to 2010
over a period of one decade. ERDAS Imagine 10 software has been used to carry
out the supervised classification using a maximum likelihood technique. The images
of the study area were categorized into five different classes, viz., agricultural land
area, settlement area, forest cover area, wasteland area, and water body area. The
result indicates that during the decadal period, the agriculture forest and settlement
area have increased about 6.22% (i.e., 25.19 km2), 0.30% (i.e., 2.66 km2), 2.17%
(20.47 km2), respectively, while area under other land categories such as wasteland
and water bodies have decreased about 6.16% (i.e., 22.67 km2) and 2.52% (i.e.,
0.22 km2), respectively. The Shuttle Radar Topographic Mission (SRTM), digital
elevation model (DEM) data have been used for determination of slope analysis and
it is found that most of the LULC changes have occurred in the area where slope
percentage was in nearly level to gentle categories. The accuracy assessment and
Kappa coefficient of both data sets have also been determined and found that in
the 2001 accuracy assessment was 85.35% and in 2010 accuracy assessment was
89.59%. The technique used in the study shows the importance of digital data-based
change detection techniques for the nature and location of a change in the study area.

4.1 Introduction
Human beings are one of the most destructive agents of nature who continuously
changes and modifying the landscape depends upon its suitability for survival and
wellbeing. Since the history of human being the land surface have witnessed the
many changes in the form of national boundary barrier, great walls, embankments,
urban planning, industrialization, settlement agricultural practice etc. Human
alteration of a landscape from natural vegetation to any other use typically results
in habitat loss, degradation, and fragmentation, all of which can have a devastating
effect on biodiversity. The changes in land use/land cover represent an important part
of the global change affecting the environment. These changes occurred by altering
(increasing or decreasing) the number, structure, or conditions of the elements
in the satellite image over various spatial and temporal scales (Stow et al. 1990;
Sreenivasulu and Bhaskar 2010). Although, quantifying, monitoring, and evaluating
the spatial and temporal dynamics of the land use land cover is quite critical for
better understanding many of the Earth’s land surface processes (Midekisa et al.
2017). Besides this, to understand these changes allow us to quantify and monitor
trends in agriculture (Ramankutty and Foley 2011), freshwater resources (Costa
et al. 2003), forest cover (Hansen et al. 2014), and disease transmission (Patz and
Norris 2004; Midekisa et al. 2014). Moreover, we are aware that land conversion is

the greatest cause of extinction of terrestrial species, of which particular concerns
are deforestation, expansion of urban centers, industrial expansions, major roads,
and railways network corridors have really created a great impact on the ecology
and survival of many species that previously existed (Tripathy et al. 1996).
Large number of researchers around the world are monitoring these changes of
land use which is a product of interactions between a society’s cultural background,
state, and its physical needs on the one hand and the natural potential of land on
the other, so that better understanding can be made among man, nature, and natural
resources (Balak and Kolarkar 1993; Chaurasia et al. 1996; Agarwal et al. 2002;
Jasrotia et al. 2012; Jasrotia et al. 2013; Taloor et al. 2018). Researchers around the
world have started to monitor land use land cover changes by involving traditional
surveys and inventories from the nineteenth century. With the passage of time and an
enhancement in the technology, remote sensing and GIS are quite advantageous as
it is economically billable and time saving for micro to macro scale LULC changes
with geographic spatial information (William et al. 1994; Yuan et al. 2005;Xiao
et al. 2006; Shalaby and Tateishi 2007; Noor et al. 2008; Prakasam 2010; Friedl et al.
2010; Dong et al. 2012;Girietal.2013; Yan and Roy 2015; Xiong et al. 2017).
The classification of the image is not completed until its accuracy assessment is not
assessed although, the applications of LULC classification is increasing day by day
with the enhancement in remote sensing technology (Congalton and Green 2008;
Martellozzo and Clarke 2011).
In recent years, there has been tremendous increase in the availability of high
performance cloud computing such as the NASA Earth Exchange (NEX) platform
which allows the processing and analysis of NASA earth observation data (Nemani
2011), Amazon Web Service (AWS) also now provides access to the Landsat data
archive, enabling analysis of this dataset on the cloud. In the recent times, Google
Earth Engine (GEE) has enhanced the scientific capability to explore and analyze as
it is a new high performance computing platform which gives access to a vast and
growing amount of earth observation data. In the recent times, Google Earth Engine
(GEE) has enhanced the scientific ability to explore and analyses of the earth surface,
as it is a new high-performance computing platform which gives access to a vast and
growing amount of earth observation data and also the processing power to analyze
these data at planetary as well as micro-scale (Midekisa et al. 2017).
The main objectives of the present study are to examine the land use/land cover
temporal changes during 2001–2010, determination of accuracy assessment, kappa
coefficient, and role of slope in land use land cover change dynamics. The study also
highlights the importance of digital change detection techniques for the nature and
location of change in the Western Doon valley.
4.2 Study Area
The Western Doon valley lies between latitude 30° 141 to 30° 3051 and longitude
77° 3805to 78° 0550 covers the total area of 898.33 km2(Fig. 4.1). The Western

Doon valley is an intermountain valley that lies between two intermittent ranges of
the Himalayas. It is bounded on all sides by mountains, with one range running from
the west to the east in a semi-circular arc; and one running at the south from Paonta
Sahib to Haridwar. The valley also forms a watershed between the Yamuna and Bindal
River in the systems. Doon or Dun is a local word for valley, particularly an open
valley in between the Siwaliks and higher Himalayan foothills. The average annual
rainfall is 2200 mm out of which 1700 mm is monsoonal. Geologically, Western
Doon valley is an asymmetrically, longitudinal structurally synclinal valley formed

of Siwalik rocks of sedimentary origin having the trend of the northwest to southeast
of Upper Tertiary Age (Jasrotia et al. 2018).
4.3 Materials and Methods
The present study was carried out using the various primary and secondary data.
These include Survey of India (SoI) topographic sheet of 1:50000 scale. Landsat
ETM +satellite images of Western Doon Valley were acquired for 2001 and 2010,
respectively, with the spatial resolution of 30 m. These datasets were obtained from
the Global Land Cover Facility (GLCF) an earth science data interface. To find out
the changes, Landsat ETM +data of 2001 and 2010 were geo-referenced and super-
vised classification was used to determine the change detection analysis by using
the maximum likelihood algorithm in ERDAS Imagine 10 software. The supervised
classification depends on the accuracy of the user, techniques, experience, and accu-
racy of his optical capability to define and detect the different signatures among the
various patterns in the satellite images. Spectral information represented by the one
spectral band is used to classify each individual pixel. The Arc GIS 10 software
was used for the integration of spatial data and the preparation of thematic maps.
Adequate field checks have been made before finalizing of thematic maps. Slope
map was prepared from SRTM, DEM data to envisage the role of slope in landscape
change dynamics. The approach used in the present study is shown in Fig. 4.2.

4.4 Results and Discussions
4.4.1 Slope Map
The slope is a measure of the steepness of a line, or a section of a line, connecting two
points and is also one of the indicators of human development in many cases. Level
and gentle slope areas are mostly developed with agricultural activities or human
settlements compared to moderate and steep slopes. The Shuttle Radar Topographic
Mission (SRTM), Digital elevation model (DEM) data were used to prepare the slope
map of the study area. The derived slope map was classified into seven categories
(Taloor et al. 2017;) such as nearly level (0–1%), very gentle (1–3%), gentle (3–5%),
moderate (5–10%), steep (10–15%), moderately steep (15–35%), and very steep
(>35%) (Fig. 4.3). It is found in the study by comparing the slope map with change
detection map that most of the changes were made in the area which has a level to
gentle slope due to human activities which suggest that anthropogenic activities play
a vital role in changing the landscape surface in the Western Doon Valley.
4.4.2 Land Use/Cover Status
The study area is classified into five major classes from Landsat TM satellite images of
2001 and 2010 are shown in Fig. 4.4 and Fig. 4.5, respectively. The different classes
analyzed from the satellite data are shown in Table 4.1. The land use land cover
study depicts that there is a positive growth in agriculture, settlement, forest cover;
negative growth in water bodies and wasteland (Fig. 4.6). The detail description of
the different classes is given in the following subheading.
Settlement area: Settlement included the area under residential, commercial,
industrial, parking and transportation facilities. In the satellite imagery, the class
was identified by blocky appearance, light bluish colored, fine to medium texture
with regular shape and varying size. An increase in the settlement area means the
expansion of mankind which has positive, as well as negative impact on the land it
surges. In the 2001 thematic layer, the area covered by settlement class is 175.07 km2
(19.49%) and increased 2.17% of the total area in 2010 as 194.54 km2(21.66%). In
the study area, it is found that most of the expansion in the settlement is in the fringes
of the earlier built up area and generally in the area with level to the gentle slope.
Agriculture land area: Agriculture appears light pink in the FCC image character-
ized by the shades of red color and textural variability including the areas cultivated
with various cultures of corn, wheat, barley, oat, potatoes, tea plantation etc. In the
land use classes of 2001, the agriculture land covers area covers 131.31 km2(14.62%)
of the total area whereas in 2010 this agricultural land covers 187.19 km2(20.84%)
of total area with an increase of 6.22%. The increase in agriculture due to popula-
tion pressure and availability of a large amount of fallow land in the Western Doon

Valley. A certain portion of the forest land is also converted into the agricultural land
by making the reckless cutting of the trees in the area adjoining to the water bodies.
Forest cover area: Forest cover includes the evergreen forests, deciduous forests,
mixed forests, shrubs (hazelnuts, willow trees) open forest in the study area Open
forest is identified by dull red-greenish color in false color composite (FCC), the
dense forest bright red color, deciduous forest shows light gray color in the image. A
complete stretch from southwest to southeast covered by the forest cover and there
major patches of forest are lying in the central parts of the study area. In 2001, LULC
the area covered by the forest cover was 89.56 km2(9.97%) and in 2010 it increases

Fig. 4.4 Land use land cover map 2001 (Source Landsat-7, ETM+)
to 92.22 km2. It is also a well-established fact that despite the increase in population
pressure and an increase in the agriculture growth in the Western Doon Valley forest
cover has a positive growth.
Wasteland area: The wasteland appears light white in FCC and fine to medium
texture covers including the uncultivated agricultural lands, fallow land, pasture,
arid land with short vegetations, stony and rocky land with no vegetation cover. The
wasteland in the study area has been decreased over the period of 2001 to 2010 by
6.6% which is a positive trend in human development. In the Western Doon valley,
4 Land Use Land Cover Dynamics Using Remote Sensing … 45
Fig. 4.5 Land use land cover map 2010 (Source Landsat-7, ETM+)
the wasteland area was mixed with agriculture and settlement and it maybe further
reduced with temporal changes in the future course of time. In the study area, the
wasteland has been converted into agriculture land, settlement, and forest covers. In
2001 the area cover by this class was 169.03 (18.82) which decreases in 2010 as
113.67 (12.65%) of the total study area with a negative growth of 6.16%.
Water bodies area: The water bodies appear cyan in color and light dark in deep
water conditions. The Yamuna and the Bindal are the two major rivers fallows in the
Western Doon Valley with a large number of seasonal tributaries that joins them from

northeast to the southwest whereas Bindal flows from northeast to west. In the land
use land cover maps, the area covered by water bodies was 333.37 km2(37.11%) in
2001 and 310.70 km2(34.59%) in 2010 showing a negative growth of 2.52% over
the period of 2001 to 2010.
4.4.3 Accuracy Assessment
Accuracy assessment has become vital with the passage of time as remote sensing
techniques emerged as one of the most powerful tools in the classification of land

use land cover. This process defines the degree of coherence of the classified image
with the ground truth of an image classification of samples reference images used
for analysis. The accuracy assessment usually evaluates the effectiveness of classi-
fiers with the help of statistical significance computation of overall accuracies. A
considerable number of references (pixels) are taken from the classified image and
made a field check visit to evaluate the correctness of the classification process. The
kappa coefficient ranges from 0 to 1; values higher than 0.7 is considered acceptable,
while those equal to or lower than 0.4 identify a very low correlation between the
classified image and the ground truth as a reference available images and maps of the
respective time period. This process was supplemented with previous knowledge and
ground checks. In the present study, the overall accuracy of the different classes was
achieved 85.35% and kappa coefficient 0.88 for 2001 dataset whereas for the data
set of 2010 the accuracy was 89.59% and Kappa coefficient was 0.91 (Table 5.2).

4.4.4 Change Detection
Based on the post-classification comparison (PCC) method was applied to change
detection analysis, which is recognized as the most accurate change detection tech-
nique, detects LULC changes by comparing independently produced classifications
of images from different data sets. In PCC each date of rectified imagery is inde-
pendently classified to fit a common land type schema (equal number and type of
land cover classes). The resulting land cover maps are then overlaid and compared
on a pixel-by-pixel basis. The change detection analysis was performed by using a
simple pixel-by-pixel mathematical combination of images for two different time
periods. The change map produced by overlaying the two classified images assisted
in locating the changes occurring in LULC classes (Fig. 4.7).
The formula used for the caluclation of rate of change has been derived from the
formula (Puyravaud et al. 2003)
r=1

At1
where, r is the rate of land cover change, and At1 and At2 are the forest cover at time
t1 and t2 respectively, In is the logarithm.

4.5 Conclusion
The study conducted in one of the most important and vital regions of India located
in the Lesser Himalayas of the Uttarakhand State. The study reveals that the major
land use in Western Doon Valley is the built-up area. During one decade, the area
under built-up land has been increased by 2.17% (19.47 km2) due to the construction
of new buildings on fallow land and wasteland and in the area adjoining to the river
beds which was earlier a part of water bodies. The agricultural and vegetation land
have been increased by 6.22% (55.88 km2) tremendously due to population pressure
and high inflation rate during the period of (2001–2010) in the Western Doon Valley
and it is also observed that most of these changes have occurred in the area which is
flat wasteland and having slope very level to gentle. Another significant fact of the
study is that the water bodies have been decreased by 2.52% (2.67 km2) which is
one of the major concerns for ecology and environment of the Western Doon Valley
where more than 2 lakhs migratory birds visit annually. Although, the forest cover
has been also increased by 2.62 km2due to the effective and efficient policies of the
administration, which is a positive sign for the growth of ecology and habitat. The
results of the present study clearly demonstrated the potential of remote sensing and
remote sensing techniques in deciphering the changing pattern of land use/cover in
a study area.

... Recent developments in R.S. and G.I.S. tools have enabled researchers to detect and analyse such changes more efficiently (Bhat et al., 2017), so that more precise research outcome data could be obtained. Several previous studies on the temperature trends of Dehradun city and Doon Valley (Agarwal et al., 2019;Jana et al., 2020a;Patidar & Sankhla, 2015;Taloor et al., 2020) have also highlighted the cause and consequences of LST rise. The major purpose of this study is to determine the NDVI, SLOPE, and NDBI values by employing change detection; to identify the area of change and by analysing the spatiotemporal variation in LULC, LST, NDVI, and NDBI; to evaluate the strength of the association between LST and NDVI, SLOPE, and NDBI using the correlation coefficient (r). ...
... The results showed that, between 1989 and 2020, a significant portion of the Agricultural land area had been converted into BUAs. At the same time, vegetation cover and open scrubland have been largely converted into agricultural land before it gets converted into built-up, supported by (Agarwal et al., 2019;Gupta, n.d.;Jana et al., 2020a;Patidar & Sankhla, 2015;Taloor et al., 2020;Thapa & Bahuguna, 2021). Based on the results statistics, the major development is directly associated with uncontrolled rapid urbanization and population growth, which further demands land use for several anthropogenic activities like residential, commercial, industrial, and infrastructural development and other concrete-led development. ...

Recent climate change has had a negative impact on a wide range of human and natural systems, and it is clear that humans influence the climate. Because, as anthropogenic influence increases, the heat output from the land surface increases, speeding up the rate of climate change. In this regard, the use of RS and GIS techniques has provided various opportunities for research to examine these changes. The current analysis is based on the Landsat 1989, and 2020. Over the study period of 31 years, the built-up regions increased in size from 44.23 km2 to 154.56 km2. Whereas, the area covered by scrubland, water bodies, and vegetation cover has significantly decreased. The LST study further supports the outcome, showing that the mean and standard deviation increased from 14.81°C±1.32(1989) to 18.82°C±1.57(2020). The study also made an effort to examine how LULC affected LST; while vegetation cover has consistently helped to lower mean LST, built-up areas and scrubland are the main drivers of mean LST rise. The LST and NDBI revealed a positive correlation, while the NDVI/SLOPE and LST showed a negative correlation. Subsequently, the multiple linear regression (MLR) models concluded that the BUAs has evolved into a serious threat to the increase in LST, but increase in vegetation cover and SLOPE would result in slight decrease in LST. the study recommended that the government create policies that restrict future land encroachment and conversion, notably of forested area and water bodies, and make an immediate effort to increase the quantity and quality of urban green cover in the study area. So that we may, respectively, minimize the potential hazard posed by future LST rise and LULC change.
... It is important to exercise caution when interpreting and using classification accuracy assessments, as they may not always accurately reflect the properties of the map [21]. Model validation was conducted to assess the accuracy of the predicted LULC map [22]. One commonly used method is the statistical Kappa method, which is calculated from the contingency table between two sets of data. ...
... Over the last four decades many studies around the world have taken place to monitor the changes of the LULC pattern which has given us enough impetus to preservation and planning of natural resources ( Amin et al., 2014 ;Mandal et al., 2019 ;Taloor et al., 2020 ) for the sustainable development of man and environment. To monitor all these spatio temporal changes, the Remote Sensing (RS) satellite data has enhanced our capabilities with rapid analysis in the Geographic Information System (GIS) which have been extensively used around the world to monitor the many kinds of changes on the surface of the Earth ( Kamini et al., 2006 ;Kumar et al., 2021 ;Chowdhury et al., 2021 ;Petroni et al., 2022 ;González-González et al., 2022 ;Taloor et al., 2021 ). ...

Land use and land cover (LULC) changes are important indicators of environmental and socioeconomic changes made by the natural and anthropogenic sources. The present study is based on the Cellular Au-tomata (CA) Markov model for predicting the LULC changes in the Tawi Basin. To decipher the spatio-temporal distributions of LULC, the Landsat images of 2010 and 2020 were used to analyse the LULC classification. Further, CA Markov model simulations of various scenarios of eight decades (2030 to 2100) were generated based on LULC of 2010 and 2020 data to know the LULC perspective changes in the Tawi Basin, which has witnessed the enormous developmental activities such as growth in settlement, population , and agriculture sector over the years. The model predicts that a population explosion leading to rapid urbanization and rural expansions. Settlement is expected to increase from 5.29% of the total area in 2020 to 13.975% in the year 2100. The CA-Markov model results paint a picture of significant changes in land use and settlement patterns in the Tawi Basin. The study serves as a crucial tool for guiding future planning effort s, urging environ-mentalists, planners, and decision-makers to prioritize sustainable practices and make informed decisions for the well-being of the region.
... Humans, being the planet's most dominant modifiers, perpetually alter land use and cover. Historically, through urbanization, agriculture, industry, settlements, and other activities, humans have reshaped the landscape to cater to their needs and ensure their survival (Taloor A.K., 2020). Furthermore, the adverse effects of climate change in recent decades, manifested as droughts, salinization, and rising sea levels, have directly impacted the patterns of land use proportion variations (Phuong et al., 2020). ...

This study investigates the changing of land cover (LC) and land surface temperature (LST) in Dhaka city over a span of three decades (1989-2019). Utilizing satellite images and remote sensing techniques, the temporal evolution of various land cover types, including built-up areas, vegetation, water bodies, and bare soil were mapped. The findings indicate a significant increase in built-up areas, accompanied by a decline in vegetation and water bodies. This transformation has led to an observable rise in LST, particularly in densely urbanized zones. The correlation analysis revealed a strong inverse relationship between vegetation cover and LST, emphasizing the cooling effect of green spaces and water bodies as well as the warming effect of dense urban areas. The study underscores the importance of proper urban planning and green infrastructure in mitigating the urban heat island effect and enhancing the livability of Dhaka city. The insights derived from this research can guide policymakers in sustainable urban development and climate adaptation strategies.
... Remote sensing is the art of collecting the earth's surface information with the help of aircraft or space-borne satellites to be utilized in applications (Sharma et al., 2013), e.g., oceanography, cryosphere, hydrology, agriculture, and weather monitoring service but not limited . In the land-use and land-cover (LULC) applications, it plays a vital role in the estimation of soil moisture and erosion, forest cover mapping, urban planning, crop yield monitoring and prediction, and management of natural resources (Bhosle et al., 2019;Taloor et al., 2020;Singh et al., 2022). With the continuous improvements in satellite imaging technology, the high-resolution earth's surface imagery is available at a huge range of spectral bands that can be utilized in numerous applications. ...

Remote sensing via hyperspectral imaging delivers the crucial earth’s surface information in narrow spectral bands, which may not be possible with multispectral imaging. The classification algorithms play a vital role in highlighting or categorizing the essential features of the earth’s surface with respect to spectral information and generate thematic maps for further processing in different applications. Therefore, it is essential to explore the impact of well-defined or emerging classifiers on hyperspectral and multispectral datasets. In the present work, the performance of various classifiers, i.e., support vector machine (SVM), feedforward neural networks (FF-NN) and maximum likelihood classifier (MLC), has been evaluated using Earth Observation-1 (EO-1) Hyperion and Landsat-8 Operational Land Imager and Thermal Infrared Sensor over a part of the North Indian states. The experimental outcomes have confirmed that the FF-NN classifier achieved higher accuracy (91.20% with Hyperion; 82% with Landsat-8) as compared to other classification methods, i.e., SVM (87.60% with Hyperion and 80% with Landsat-8) and MLC (84.40% with Hyperion and 72.40% with Landsat-8). This study is important in terms of exploring the potential of hyperspectral imaging with different classification algorithms in various emerging applications.
... Although it was a problem for a long period [19], a well-known soil degradation process results mainly from anthropogenic activities and animal overpopulation. Landscape modifcation by human alteration, particularly from forestland to other land uses, has had a signifcant impact on soil degradation, fragmentation, and habitat losses and strongly afects biodiversity [20]. Humans are changing and modifying the natural environment via their day-to-day entraction [18,21]. ...

One of Ethiopia’s threatening environmental problems is soil erosion. Minimizing soil erosion to the tolerable level needs evidence-based sustainable land management. This study aimed to investigate the soil erosion rate and its relation with site physical characteristics (slope, land use/cover, and soil properties) using the GIS-based RUSLE model in the Majang watershed. Climate data, DEM, Landsat image, and soil map were used to model soil erosion by applying the RUSLE model. The results showed that cultivated land is the most vulnerable type of land use to soil loss (35.1·t ha−1 year−1) followed by grasslands (19.6·t ha−1 year−1) in the watershed. Conversely, forest land is the least vulnerable land use and generates a very low amount of soil loss (12·t ha−1 year−1). Similarly, the average soil loss of the watershed is strongly related to the slope gradient. The model result indicated that a high amount of soil loss was observed in very steep slope land (62.8·t ha−1 year−1) but lower in the gentle slope (13.6·t ha−1 year−1). Soil types and their characteristics have greater roles in generating a high amount of soil loss. Acrisols, which lack organic matter content, have experienced a high soil loss rate (20·t ha−1 year−1). This implies soil loss is highly associated with site-specific characteristics such as slope gradient, land cover/use, and soil condition. The greatest share of the soil loss was estimated from steep slopes, bare and cultivated land, and less fertile soils. Therefore, building an integrated participatory approach needs immediate attention, and all farmers and stakeholders need to focus on on-site prioritization and invest more in conserving vulnerable areas.

The present study represents a significant understanding, employing cutting-edge Remote Sensing (RS) and Geographic Information System (GIS) technologies by conducting a comprehensive landslide susceptibility modelling in the Doda, Kishtwar, and Ramban (DKR) districts of the Union Territory of the Jammu and Kashmir in the NW Himalaya. The primary objective of this study is to determine the areas that are at high risk of landslides and accordingly classified these risk zones into five distinct categories, ranging from very high (VH) to very low (VL) susceptibility. To achieve this, a multifaceted approach, involving the utilization of various terrain thematic layers in the GIS environment was applied. The preferred framework employed in this study is the Weighted Overlay (WO) analysis. The final outcome of the study is the final landslide susceptibility map which is a significant and valuable resource for a wide range of stakeholders, including decision-makers, land managers, and local communities. It equips these stakeholders with the information and insights required to adopt proactive strategies in response to the identified landslide susceptibility zones.

Land surface temperature (LST) is a key variable used in climatic modeling, monitoring, and assessing urban heat islands (UHI) impacts. The extraction of LST and normalized difference vegetation index (NDVI) from earth observation satellite data for continuous monitoring at a local or regional scale is a challenging task. In this paper, a Python-based semi-automatic tool (LS8pyCalc) has been developed based on USGS-provided equations to calculate LST and NDVI using LANDSAT-8 (LS8) images with minimum input parameters using graphical user interface (GUI). The developed tool was successfully implemented in the Punjab Rice Wheat Agroclimatic Zone (PRW-ACZ). The tool’s accuracy was validated through in situ observations and compared with Google Earth Engine (GEE) derived Moderate Resolution Imaging Spectroradiometer (MODIS) product using eight statistical parameters at 43 sites having varieties of geo-features (sparse and dense vegetated, built-up area, and water bodies). Land use land cover (LULC) extracted from Copernicus Global Land Cover Layers was used to correlate the outcomes. The derived LS8-LST showed that the study area experiences a wide range of surface temperature from 39.70 to 21.18 °C same as NDVI ranges −0.19 to 0.60. The results showed mean absolute error (MAE) and R2 ranges of 0.83–1.08 and 0.88–0.96, respectively, with field observation. The value of MAE and R2 with the MODIS dataset was observed as 4.26–5.42 and 0.46–0.87, respectively, with an overall insignificant error (max < 12%). The study would be helpful in LST, UHI, and vegetation monitoring at national and international scales due to the ease of large data processing.

Quantifying and monitoring the spatial and temporal dynamics of the global land cover is critical for better understanding many of the Earth’s land surface processes. However, the lack of regularly updated, continental-scale, and high spatial resolution (30 m) land cover data limit our ability to better understand the spatial extent and the temporal dynamics of land surface changes. Despite the free availability of high spatial resolution Landsat satellite data, continental-scale land cover mapping using high resolution Landsat satellite data was not feasible until now due to the need for high-performance computing to store, process, and analyze this large volume of high resolution satellite data. In this study, we present an approach to quantify continental land cover and impervious surface changes over a long period of time (15 years) using high resolution Landsat satellite observations and Google Earth Engine cloud computing platform. The approach applied here to overcome the computational challenges of handling big earth observation data by using cloud computing can help scientists and practitioners who lack high-performance computational resources.

The automation of agricultural mapping using satellite-derived remotely sensed data remains a challenge in Africa because of the heterogeneous and fragmental landscape, complex crop cycles, and limited access to local knowledge. Currently, consistent, continent-wide routine cropland mapping of Africa does not exist, with most studies focused either on certain portions of the continent or at most a one-time effort at mapping the continent at coarse resolution remote sensing. In this research, we addressed these limitations by applying an automated cropland mapping algorithm (ACMA) that captures extensive knowledge on the croplands of Africa available through: (a) ground-based training samples, (b) very high (sub-meter to five-meter) resolution imagery (VHRI), and (c) local knowledge captured during field visits and/or sourced from country reports and literature. The study used 16-day time-series of Moderate Resolution Imaging Spectroradiometer (MODIS) normalized difference vegetation index (NDVI) composited data at 250-m resolution for the entire African continent. Based on these data, the study first produced accurate reference cropland layers or RCLs (cropland extent/areas, irrigation versus rainfed, cropping intensities, crop dominance, and croplands versus cropland fallows) for the year 2014 that provided an overall accuracy of around 90% for crop extent in different agro-ecological zones (AEZs). The RCLs for the year 2014 (RCL2014) were then used in the development of the ACMA algorithm to create ACMA-derived cropland layers for 2014 (ACL2014). ACL2014 when compared pixel-by-pixel with the RCL2014 had an overall similarity greater than 95%. Based on the ACL2014, the African continent had 296 Mha of net cropland areas (260 Mha cultivated plus 36 Mha fallows) and 330 Mha of gross cropland areas. Of the 260 Mha of net cropland areas cultivated during 2014, 90.6% (236 Mha) was rainfed and just 9.4% (24 Mha) was irrigated. Africa has about 15% of the world’s population, but only about 6% of world’s irrigation. Net cropland area distribution was 95 Mha during season 1, 117 Mha during season 2, and 84 Mha continuous. About 58% of the rainfed and 39% of the irrigated were single crops (net cropland area without cropland fallows) cropped during either season 1 (January-May) or season 2 (June-September). The ACMA algorithm was deployed on Google Earth Engine (GEE) cloud computing platform and applied on MODIS time-series data from 2003 through 2014 to obtain ACMA-derived cropland layers for these years (ACL2003 to ACL2014). The results indicated that over these twelve years, on average: (a) croplands increased by 1 Mha/yr, and (b) cropland fallows decreased by 1 Mha/year. Cropland areas computed from ACL2014 for the 55 African countries were largely underestimated when compared with an independent source of census-based cropland data, with a root-mean-square error (RMSE) of 3.5 Mha. ACMA demonstrated the ability to hind-cast (past years), now-cast (present year), and forecast (future years) cropland products using MODIS 250-m time-series data rapidly, but currently, insufficient reference data exist to rigorously report trends from these results.

Dimensionality reduction (DR) is a widely used technique to address the curse of dimensionality when high-dimensional remotely sensed data, such as multi-temporal or hyperspectral imagery, are analyzed. Nonlinear DR algorithms, also referred to as manifold learning algorithms, have been successfully applied to hyperspectral data and provide improved performance compared with linear DR algorithms. However, DR algorithms cannot handle missing data that are common in multi-temporal imagery. In this paper, the Laplacian Eigenmaps (LE) nonlinear DR algorithm was refined for application to multi-temporal satellite data with large proportions of missing data. Refined LE algorithms were applied to 52-week Landsat time series for three study areas in Texas, Kansas and South Dakota that have different amounts of missing data and land cover complexity. A series of random forest classifications were conducted on the refined LE DR bands using varying proportions of training data provided by the United States Department of Agriculture (USDA) National Agricultural Statistics Service (NASS) Cropland Data Layer (CDL); these classification results were compared with conventional metrics-based random forest classifications. Experimental results show that compared with the metrics approach, higher per-class and overall classification accuracies were obtained using the refined LE DR bands of multispectral reflectance time series, and the number of training samples required to achieve a given degree of classification accuracy was also reduced. The approach of applying the refined LE to multispectral reflectance time series is promising in that it is automated and provides dimensionality-reduced data with desirable classification properties. The implications of this research and possibilities for future algorithm development and application are discussed.

Malaria is a major global public health problem, particularly in Sub‐Saharan Africa. The spatial heterogeneity of malaria can be affected by factors such as hydrological processes, physiography, and land cover patterns. Tropical wetlands, for example, are important hydrological features that can serve as mosquito breeding habitats. Mapping and monitoring of wetlands using satellite remote sensing can thus help to target interventions aimed at reducing malaria transmission. The objective of this study was to map wetlands and other major land cover types in the Amhara region of Ethiopia and to analyze district‐level associations of malaria and wetlands across the region. We evaluated three random forests classification models using remotely sensed topographic and spectral data based on Shuttle Radar Topographic Mission (SRTM) and Landsat TM/ETM+ imagery, respectively. The model that integrated data from both sensors yielded more accurate land cover classification than single‐sensor models. The resulting map of wetlands and other major land cover classes had an overall accuracy of 93.5%. Topographic indices and subpixel level fractional cover indices contributed most strongly to the land cover classification. Further, we found strong spatial associations of percent area of wetlands with malaria cases at the district level across the dry, wet, and fall seasons. Overall, our study provided the most extensive map of wetlands for the Amhara region and documented spatiotemporal associations of wetlands and malaria risk at a broad regional level. These findings can assist public health personnel in developing strategies to effectively control and eliminate malaria in the region.

Hydrogeochemical investigation was carried out in the Western Doon valley, to understand the geochemistry of the groundwater and to assess the overall physic-chemical characteristics. To attempt this goal, 50 groundwater samples of dug well and tube well were collected using pre-cleaned polyethylene containers from the different geological formations of the study area. The physical and chemical parameters of the analytical results of groundwater samples were compared with the standard guideline values recommended by the World Health Organization for drinking and public health standards. Thematic layers pertaining to Ca²⁺, Mg²⁺, NO3⁻ and total hardness (TH) were generated using GIS platform. The hydrochemistry of groundwater quality for drinking purpose was evaluated by plotting the cations, anions in the Piper's Trilinear diagram, which indicates the alkaline and weak acids dominance, and carbonate hardness exceeds 50%. Expanded durov diagram implies Ca²⁺–HCO3⁻ dominance, indicating recharging of water in sandstone aquifer. Based on the hydrogeochemical analysis for irrigation quality, certain parameters like carbonate hardness, sodium adsorption ratio, sodium percent, salinity hazard, residual sodium carbonate, Kelley's ratio, index of base exchange and permeability index were calculated. Besides this, a comparison of the groundwater quality in relation to drinking water quality standards shows that most of the groundwater samples are good for drinking as well as irrigation purposes and controlled by lithology apart from other local environmental conditions as the concentration of the cations and anion increases in the post-monsoon season. The results of hydrogeochemical are helpful to generate the baseline information and roadmap for future research on groundwater resources to assess the water quality in relation to agricultural and domestic uses in the Western Doon valley.

We discuss the tectono-geomorphic evaluation of the Binta basin (Lesser Himalaya, India) through quantitative and qualitative morphotectonic analyses at the watershed scale. The basin, drained by the Gagas River and its tributaries, is situated in the zone of the active North Almora Thrust (NAT). Developments of deeply incised V-shaped valleys indicate increased incision capability of streams in response to steepening of hillslope gradients due to neotectonic activity. Prominent features, e.g., off-setting of the NAT by later formed subsidiary faults, deflection of streams, vertical fault scarps, formation of palaeolakes, river ponding and development of fluvial terraces were likely responsible for reformation of the landscape and drainage system due to tectonic perturbations. The morphometric parameters using digital terrain data in the GIS technology and focusing on hydrography (stream length-gradient index, ratio of valley floor width to valley height, transverse topographic symmetry factor and topography (local relief and relief anomaly) verify the rejuvenation of landscape. Anomalously high and low values of stream length-gradient indices of main tributary streams associated with faults and multiple knickpoints along the channel profiles may have been associated with deformational events. Our observations on the tectonic instability of the faulted basin support the existing GPS based studies indicating the maximum crustal shortening and strain rate with a maximum aerial strain of 6-8 × 10-7 strain/year and deformation of ~15 mm/year immediately north of the NAT, and proving that this tectonically active zone is vulnerable for the future earthquakes. © 2017 Gebr.

Disease emergence events have been documented following several types of land use change. This chapter reviews several health-relevant land use changes recognized today, including: 1) urbanization and urban sprawl; 2) water projects and agricultural development; 3) road construction and deforestation in the tropics; and 4) regeneration of temperate forests. Because habitat or climatic change substantially affects intermediate invertebrate hosts involved in many prevalent diseases, this chapter provides a basic description of vector-borne disease biology as a foundation for analyzing the effects of land use change. Urban sprawl poses health challenges stemming from heat waves exacerbated by the "urban heat island" effect, as well as from water contamination due to expanses of impervious road and concrete surfaces. Dams, irrigation and agricultural development have long been associated with diseases such as schistosomiasis and filariasis. Better management methods are required to address the trade-offs between expanded food production and altered habitats promoting deadly diseases. Deforestation can increase the nature and number of breeding sites for vector-borne diseases, such as malaria and onchocerciasis. Human host and disease vector interaction further increases risk, as can a change in arthropod-vector species composition.
