Keywords: Urbanization, Land use and land cover (LULC), Machine Learning, Landscape Modelling, Fragmentation analysis, Environmentally Sensitive Regions (ESRs)
Abstract: Rapid urbanization and industrial growth have led to the degradation of natural resources, necessitating
a quantitative analysis of landscape dynamics for sustainable planning. Urban green ecosystems and
wetlands, crucial for ecological balance, are being fragmented due to haphazard development activities,
impacting biodiversity and ecological services. The availability of spatiotemporal remote sensing data
with advancements in artificial intelligence (AI) and machine learning (ML) algorithms has aided in
assessing the ecological status in urban environments, markedly revealing complex patterns and
interactions. The current study presents landscape dynamics in the Bengaluru Urban district from 1973
to 2022 using a supervised machine learning technique based on the Random Forest algorithm with
temporal Landsat data, which showed a 51.86% increase in the built-up area and a 26.28% decrease in
the green cover. Computation of fragmentation indices showed a decline of the native green cover by
177.2 sq. km. in the southern part of the district. In urban landscapes, this results in the loss of green
spaces and increased urban heat island effects. Modelling and geo-visualization tools are essential for
anticipating changes in land use and aiding decision-making. Likely land use changes are predicted
using the Cellular Automata Markov model considering the base case scenario. The analyses revealed
a further possible increase in built-up to 1536.08 sq. km, with a decrease in green cover by 14.32 sq.
km by 2038, and the disappearance of water bodies, which highlights the need to mitigate the adverse
impacts of land use changes through planned urbanization considering the environment and livelihood
of local communities. Insights into land use dynamics helped to delineate Environmentally Sensitive
Regions (ESRs) at disaggregated levels and the design of Decision support systems for implementing
conservation strategies and mitigation of ecological impacts. Based on bio, geo, climatic, ecological,
and social parameters there are 6.79 sq km and 1.75 sq km under ESR1 and ESR2 respectively, showing
highly sensitive regions in Bangalore Urban district.

Abstract: Changes in the climate have been posing a critical environmental and developmental challenges
threatening the livelihood of people. Natural resource-rich regions are a foundation for human societies,
shaping economic development, social organization, and cultural expression. Yadgir district
consistently ranks last in the state for socio-economic development. This disparity is further exacerbated
by declining agricultural productivity due to drought events. Assessment of landscape dynamics reveals
that the spatial extent of the agricultural land had increased from 77.27 km
2
(1973) to 89.41 km
2
(2022),
but the productivity has come down due to erratic rainfall patterns and pest attacks. Due to the
population growth during the last five decades, the need for housing and industrial infrastructure has
increased the built-up area from 12.89 km
2
(0.24%) in 1973 to 31.33 km
2
(0.60%) in 2022. With the
increase in the agricultural area and built-up area, the forest and scrubland area has declined from 87.66
km
2
to 60.51 km
2
, and 632.21 km
2
to 276.98 km
2
respectively. The study has utilized the machine
learning approach for the classification of land uses. Random forest is an ensemble learning algorithm
that possesses the unique ability to handle high-dimensional datasets with thousands of input variables
and estimate the relative importance of each variable in the classification process, aiding in
understanding the model's decision-making. The study has predicted the likely land use using the CAMarkov
method

The study identified that 8% of the district are NRRR 1 (6 grids), 7% are NRRR 2 (5 grids), 29% are
NRRR 3 (27 grids), and the remaining 57% of geographical area are NRRR 4 (57 grids). The analysis
emphasizes a multi-pronged approach that balances resource utilization with availability to ensure
environmental sustainability. Strategies include adopting climate -resistant crops, lakes and tanks
rejuvenation to enhance rainwater harvesting, sustainable water management practices, investments in education, women's empowerment, cluster-based development with the skill development of local
youth.

Keywords: Land use dynamics, Machine learning, Random Forest, Modeling, Natural Resource-Rich Regions (NRRRs)
Abstract: Natural Resource-Rich Regions (NRRRs) are characterized at disaggregated levels by considering distinct
bio-geo-climatic, ecological, hydrological, energy, and social factors. The current study examines the
multifaceted concept of sustainable economic development within natural resource-rich regions. It extends
beyond solely focusing on economic growth, recognizing the crucial role of ecological resilience
(environmental protection) and human well-being. To achieve this, the study adopts an interdisciplinary
approach, investigating the interplay of key factors. Anthropogenic activities have adversely affected the
regime of ecology, biology, and hydrology resulting in the degradation of natural resources. Kalaburagi is
located in the northern Karnataka state dominated by agricultural land and known as the “toor bowl” of
Karnataka contributing 40% of the production of the state. The district showing immense growth in dal
mills, cement, sugar industries, etc to promote industrial development under Industrial Policy 2014-19
announced by the state government. Supervised machine learning technique - Random Forest (RF) has been
used to assess land use dynamics on a temporal scale. Spatio-temporal analysis of land use dynamic reveals
that built-up had increased from 0.26% in 1973 to 1.22% in 2022 due to the greater emphasis on setting up
of MSME units and cement industries in the district, the water body has increased from 0.12% in 1973 to
1.09% in 2022. Forest cover declined from 4.02% in 1973 to 1.52% in 2022. The NRRRs analysis reveals
that 8 grids (5% area) of the Kalaburagi district fell under NRRR1 (highly sensitive), 15 grids (9% area)
under NRRR2 (high sensitive), 52 grids (32%) under NRRR3 (moderately sensitive), and the rest under
103 grids (54%) representing NRRR4 (low sensitive). There is a decisive need to frame a systematic
structure that would aid in the sustainability of natural resources and prevent the over-exploitation of natural
resources.

Keywords: landscape dynamics, LULC, forest fragmentation, CA-Markov, Random Forest, Machine Learning, Ecological Fragile Regions (EFRs)
Abstract: The landscape is a complex mosaic of environmental elements, each with its unique characteristics.
However, the degradation of landscapes, often induced by changes in land use due to unplanned
developmental activities, poses significant challenges, including exacerbating global warming,
escalating greenhouse gas emissions, and compromising carbon sequestration capabilities through
erosion. Hence, it is imperative to understand landscape dynamics for adopting sustainable measures
through the prudent management of natural resources. The utilization of spatial data from spaceborne
sensors, coupled with advancements in machine learning algorithms, presents a promising avenue for
comprehensively analysing and monitoring landscapes. The current study highlights the application of
machine learning techniques based on Random Forest (RF) algorithm, for mapping spatiotemporal
changes in this region using temporal remote sensing data (Landsat) from 1973 to 2021 in Hassan
district, Karnataka, a region characterized by diverse agroclimatic zones ranging from hot moist subhumid
areas to hot, dry semi-arid plains. The study provides valuable insights that can contribute
significantly for quantifying, monitoring, and understanding landscape dynamics, which are pivotal for
framing stringent policy measures aimed at fostering sustainable development.
The findings highlight that the eastern part of the district is predominantly covered by agriculture
(34.24%) and horticulture (50.92%) in 2021. Urban expansion (0.53% to 2.11%) and agricultural
activities have encroached upon forested areas (14.79% to 6.44%) over the past five decades. The
Cellular Automata-Markov model, to forecast future land use patterns indicated a concerning decrease
in forest cover (3.77%) coupled with an expansion of paved surfaces (5.49%) with agricultural (27.54%)
and horticultural (55.15%) lands, driven primarily by increasing agricultural practices and the
cultivation of cash crops like coffee and coconut. The study offers critical insights into of Ecological
Fragile Regions (EFRs) based on a comprehensive assessment of bio-geo-climatic-social characteristics
identifying 19% as EFR1 (most fragile), 38% EFR2 (fragile), 36% EFR3 (moderately fragile) and 7%
EFR4 (less fragile). This enables policymakers to prioritize conservation efforts and implement targeted
measures for ecological restoration and sustainable management of natural resources.
The study emphasizes the importance of adopting sustainable development measures to mitigate the
adverse impacts of land use changes and ensure the long-term ecological resilience of the landscape.
By integrating spatial information of EFRs with policy interventions, stakeholders can collectively work
towards conserving biodiversity, preserving ecosystem services, and promoting sustainable
development in the Hassan district.

Abstract: Eco-sensitive regions (ESR) are the Livelihood Support Regions (LSR) with high sensitivity
and environmental fragility, where unplanned developmental activities would cause large-scale
disturbances in the natural structure of the biological communities and natural habitats,
affecting the ecosystem processes. Integrated landscape assessment including biological,
geological, climatic, ecological, environmental, and social characteristics is required to
delineate ESRs which will aid in the conservation of ecological balance in the environment for
planning interventions to ensure sustainable development.
Landscape consists of interacting diverse ecosystem elements, governed by the natural
processes, and the heterogeneity depends on the land use land cover (LULC) dynamics.
Alterations in the LULC due to unplanned anthropogenic activities have induced changes in
the landscape structure leading to ecological imbalance evident from alterations in the
hydrologic regime, the decline in ecosystem services, etc.
Accelerated unplanned developmental activities in recent times, have resulted in enhanced
levels of pollutants, barren hilltops, loss of agriculture productivity, and conversion of
perennial streams to intermittent or seasonal, etc. Impacts such as loss of life and property,
reduction in the crop yield, the prevalence of vector borne diseases, acute water scarcity,
recurring floods, and droughts, global mean surface temperatures, alteration in spatial patterns
of rainfall and intensity, etc., due to changes in the climate with global warming has drawn the
attention of decision-makers and researchers, which necessitated delineation of ecologically
fragile regions at disaggregated levels for implementing location specific conservation
measures.
Land use and land cover (LULC) assessment using temporal remote sensing data provides
insights into landscape status, which is crucial for the prudent management of natural resources.
Integrated spatial analyses with LULC information with social, ecological, hydrological, biogeo-climatic,
and environmental variables would aid in the prioritization of ecologically
sensitive regions (ESRs). The current study investigates the spatial extent of ESRs with the
help of landscape dynamics from 1989 to 2019 in Haveri district, Karnataka, India. Haveri
district is known for its famous Blackbuck sanctuary, Bankapura Fort. Agriculture dominates the region with 85% land use. The district has shown an increase of built-up by 2%. Dairy and
poultry activities are major activities. With the loss of forest cover by a value of 1.6%, the
region has majorly dry deciduous species. The fragmentation analysis showed a decrease in
interior forest by 1.3%, indicating the stress due to anthropogenic pressure on native forest
cover. Modeling of LU in the Haveri district showed a reduction in agriculture class by 3.52%,
an increase in built-up increase of 3.27 %, and a forest reduction of 0.13%. Ecologically
sensitive region analysis showed the ESR1 region (8 grids) in the Ranebennur taluk of
Blackbuck Sanctuary and the Shiggaonv taluk of the Bankapura fort. The conservation of these
regions is the prime concern for protecting the diversity. ESR 2 (18 grids) covers the region of
moderate sensitivity with extensive productive agriculture lands, producing Maize, paddy,
jowar, and ragi, where large-scale development activity should be restricted with no
encroachments and land conversion. Still, small-scale industries like agro-based and IT
investments can be encouraged. ESR 3 & 4 (31 & 2 grids) cover a large portion of agricultural
lands with scope for sustainable development.

Keywords: TESV, NPV, Ecosystem valuation, Wetland resources, Ecosystem benefits
Abstract: Wetland ecosystems provide diverse services to sustain livelihoods, which include the provision
of food, fish, water, etc. (provisioning services), moderation of microclimate, carbon sequestration,
groundwater recharge, remediation (regulating services), and aesthetic, spiritual, recreational, and
information (cultural services). Despite being one of the most productive ecosystems, wetlands are
being mismanaged due to a lack of knowledge of ecosystem services and economic worth. This
necessitates the valuation of ecosystem services for valuable insights into their economic and
ecological worth, which would help evolve appropriate policy initiatives for sustainable
management and conservation of fragile lifeline ecosystems at decentralised levels. In this context,
an attempt has been made to value the ecological and economic worth of four wetlands in
Bangalore City through standard protocol by computing the total ecosystem supply value
(aggregation of provisioning, regulating, and cultural services: TESV) and the net present value
(NPV). The Hebbal wetland has the highest amounts of TESV (INR 51.20 million/year) and NPV
(INR 1317.48 million) compared to Nagavara, Sankey, and Mathikere. The major contribution is
from the regulating services, and the economic worth assessment highlights the vital role played
by wetlands in sustaining the livelihood of the local people and the urgent need for prudent
management of wetland ecosystems, involving all stakeholders to ensure cooperation and active
participation in the conservation endeavour.

Abstract: Wetlands, transitional lands bridging the gap between terrestrial and aquatic ecosystems, are among the most diverse and
productive ecosystems, with biophysical interactions that provide numerous ecological, economic, and social benefits for human wellbeing. These
vital
ecosystems sustain ecological processes to provide services such as nutrient cycling, water purification, reducing
pollution, carbon sequestration, groundwater recharge, flood reduction, erosion control, habitats for aquatic biota (Fig. 1), education
opportunities, aesthetics, and recreation (Ramachandra et al., 2021; Ramachandra, 2022). In this context, World Wetlands Day is
celebrated every year on 2 February to raise global awareness about the vital role of wetlands for human well-being and commemorate
nd
the adoption of the Convention on Wetlands on 2 February 1971 in the Iranian city of Ramsar. The Convention underscored sustainable
and wise use of wetlands while advocating ecosystem approaches for the preservation of fragile ecosystems. Currently, 172 Ramsar
Convention Contracting Parties and 2,500 Ramsar Sites totalling 2.5 million square kilometers are designated Ramsar Wetlands of
International Importance. There are 80 wetlands of international significance in India (https://www.ramsar.org/) spanning 1,332,200 ha

Abstract: Natural Resource Rich Regions (NRRRs) are ecologically and economically vital regions that support the livelihood of
people through the sustained ecosystem process involving interaction among biotic and abiotic elements. Identifying
NRRRs, considering spatially ecological, geo-climatic, biological, and social dimensions, would help in conservation
planning and prudent management of natural resources as per the Biodiversity Act 2002, Government of India. Changes
in the landscape structure would lead to alterations in the composition and health of these regions with irreversible
changes in the ecosystem process, impacting the sustenance of natural resources. Landscape dynamics is assessed by
classifying temporal remote sensing data using the supervised machine learning (ML) technique based on the Random
Forest (RF) algorithm. Additionally, predicting likely land use changes in ecologically fragile areas would help formulate
appropriate location-speciic mitigation measures. Modeling likely land uses through the simulation of long-term spatial
variations of complex patterns has been done through the CA–Markov model. Prioritization of NRRRs at disaggregated
levels highlights that 12% of the total geographical area of the district is under NRRR 1 and NRRR 2, 54% of the total
geographical area under NRRR 3, and the rest of the region under NRRR 4. The current study emphasizes the need for
robust decision support systems to aid in efective policy formulation for conserving and restoring natural resources.

Subject: Biomonitoring of urban lakes through microalgae
Keywords: Lake, Microalgae, Water quality, Pollution, CCA
Abstract: Biomonitoring entails monitoring the quality of an ecosystem through representative biota, which responds
to environmental changes through alterations in morphological, physiological, biochemical, molecular,
and genetic traits. The sustained inflow of untreated wastewater due to point and non-point sources has
been putting significant strain on aquatic ecosystems, leading to a decline in aquatic biodiversity, the loss
of vital habitats for sensitive biota, and consequent erosion in ecosystem services. Microalgae constitute the
primary producers in aquatic ecosystems and serve as pollution indicators as they respond to changes in
water quality. This necessitates an understanding of microalgae dynamics in relation to environmental
factors for prudent management of aquatic resources. The study examines microalgal composition and
water quality in Sankey and Mathikere lakes, Bangalore, revealing pollution from untreated wastewater in
Mathikere Lake, which exhibits high physicochemical parameters. The microalgae composition in both
lakes varied in response to the water quality and across seasons. Multivariate analyses through nonparametric
canonical correspondence analysis (CCA) demonstrate linkages between microalgal composition
and
water quality parameters in both lakes. Nutrient enrichment leading to eutrophic conditions with the
profuse
growth of invasive exotic macrophytes has declined microalgal diversity, suggesting immediate
interventions
to mitigate pollutants to improve the chemical integrity of waterbodies.

Abstract: Carbon sequestration constitutes a vital ecological function executed by ecosystems to mitigate global warming due to the burgeoning sustained anthropogenic activities which release greenhouse gases (carbon dioxide, methane, carbon monoxide, etc.). The current study evaluates carbon dynamics in forest ecosystems through the lnVest model with temporal land use analyses using remote sensing data from 1973 to 2021 in the Chikamagaluru district of Kamataka. Land use dynamics were assessed using temporal remote sensing data through a machine•
/earning-basedsupervised Random Forest algorithm, which shows
a decline In forest cover of 28.98%, an increase in agricultural area by 5.31%, and horticulture by 42.52% in the last five decades, which has led to the depletion of carbon stock by 30683.81 Gg. Land use changes have a long-term effect on climatic variables, leading to changes in local temperature, annual rainfall, and number of rainy days in the study area.

Subject: Bangalore Lakes Information System (BLIS) for Sustainable Management of Lakes
Keywords: BLIS, Lakes, Urbanization, Biodiversity, Restoration, Ecosystem services
Abstract: Wetlands (lakes, tanks, ponds, etc.), transitional lands linking
hydrologically
the terrestrial
ecosystem with aquatic ecosystems
with
biophysical interactions, are
the most productive
and diverse ecosystems
and provide
numerous
ecological, economic, and social beneits
for human well-being. These vital ecosystems sustain ecological
processes
to
provide
services
such
as
nutrient
cycling,
water
puriication,
reducing
pollution, carbon sequestration, groundwater
recharge,
provision
of ish, fodder,
fuel, and water,
lood reduction,
erosion
control,
aquatic
biota habitats, education opportunities,
aesthetics, and recreation.
However,
due to globalization, these fragile ecosystems are
vulnerable
to unplanned developmental
activities and
rapid urbanization,
leading
to large-scale land cover changes and hydrologic
regimes.
The
sustained
inlow of untreated
wastewater (from
the industrial and domestic
sectors) into wetlands has altered
the chemical integrity,
which necessitates
inventorying,
mapping,
and
regular
wetland
monitoring
to
evolve
conservation
strategies. Integrating spatial and non-spatial data, analysis,
and visualization with decision models through
decision support
systems
enables informed
decisions. In this context, the Bangalore
Lake
Information
System (BLIS) is designed with information
on water quality,
biodiversity (microalgae,
zooplankton, ichthyofauna, macrophytes,
and
birds),
threats
(encroachments,
inlow of untreated
sewage, etc.)
and
ecosystem services of lakes in Bangalore,
Karnataka
State, India.
Rapid
large-scale land use changes have resulted
in an alteration in the
hydrologic
regime,
the loss of habitats, and the disappearance of native
species.
BLIS empowers decision-making through
knowledge of lake
distribution
in terms
of the physical, chemical, and biological aspects
and
the value of ecosystem services, which is crucial for evolving strategies
for prudent management of water bodies in Greater
Bangalore.

Abstract: Freshwater ecosystems are one of the world's richest sources of biological diversity. Environmental quality and biodiversity in freshwater ecosystems are interrelated, as the interaction helps to perform diverse functions, which are valuable and essential for the sustainability of biotic communities. However, freshwater ecosystems in urban landscapes are undergoing stress due to overexploitation of biotic species, introduction of exotic species, sustained inflow of point sources of pollution and alterations in the ecological niche. Conservation of fragile eco• systems in urban landscapes to sustain native biodiversity requires comprehensive studies through regular moni• toring to understand variations in abiotic (physico-chemical) characteristics with composition of biotic elements at trophic levels. The current study investigates the trophic composition and water quality status in freshwater lakes in Bangalore. The study reveals that the diversity of fish, zooplankton and microalgae varied with the physico• chemical characteristics of lakes. The water quality results showed that Hebbal lake was more polluted than Nagavara lake. Multivariate analyses reveal that the density of primary consumers, ionic parameters and dissolved oxygen are the main factors influencing the fish population. These findings provide insights for adopting sustain• able management approachesthrough a deeper comprehension of the dynamics of a lake ecosystem, which strength•
ens the conservation of fragile ecosystems.
