Abstract: The United Nations Climate Change Conference COP 28 was held and concluded in Dubai. It is particularly important as the first ‘global stocktake’, a process for countries and stakeholders to examine the progress towards meeting the goals of the Paris Agreement. The conference outcome was a revelation of the slow progress in most areas of climate action. Consequently, nations collectively made a pronouncement on the way forward to accelerate climate action. As usual, transitioning from fossil fuels to renewable energy sources was one of the focus areas.

Keywords: Ecological fragility, spatial decision support system (SDSS), endemic taxa, energy. Ecology, bio-geo-climatic aspects
Abstract: Ecological sensitivity or fragility refers to the permanent and irreparable loss of extant life forms or significant damage to the natural processes of evolution and speciation with the alterations in the ecological integrity of a region. The comprehensive knowledge of the ecological fragility of a region is quintessential for evolving strategies for conserving the area, which entails identifying factors responsible for ecological sensitiveness, including landscape dynamics, and visualizing future transitions to mitigate the problems of haphazard and uncontrolled development approaches. The region witnessed large-scale land cover changes during the past century due to unplanned developmental activities involving industrialization. Globalisation and relaxing market norms led to rapid urbanisation with large-scale land cover changes. This necessitates implementing mitigation measures involving stakeholders to address the impacts through location-specific conservation measures. Framing conservation and sustainable developmental policies entail delineating ecologically sensitive regions by integrating bio-geo-climatic, ecological, and social factors representing the dynamics of socioecological systems, impacts, and drivers.

Keywords: Natural Resource Rich Regions; Land use Land cover; Random Forest; Modeling; Sustainable Development; Supervised classification; Machine Learning.
Abstract: 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, bio-geo-climatic, and environmental variables would aid in the prioritization of natural resources-rich regions (NRRRs). The current study assesses the LULC change in an agrarian district using temporal remote sensing data through a supervised machine learning technique- Random Forest (RF). The study reveals that built-up area had increased from 0.23% (1973) to 1.04% (2022), agricultural area had increased from 84.55% (1973) to 93.43% (2022), water body had increased from 0.38% (1973) to 0.92% (2022). There has been an increase in paddy cultivation spatial extent from 0.74% (1973) to 18.41% in the region with the increase in the extent of water bodies due to the Krishna and Tungabhadra River. The condition of forests assessed through fragmentation metrics indicates the decline of intact forest cover from 4.19% (in 1973) to 3.08% (in 2022), and non-forest area accounted for 95.87% in 2022 from 92.03 % in 1973. The likely land uses in 2022, 2030, and 2038 are predicted using Cellular Automata. The simulated LU for 2038 shows the likely increase in built-up by 671 km 2 with a decline of agriculture land by 1159.33 km 2 and an expansion of the road network and industrial area. This necessitates the identification of natural resources rich regions (NRRRs) for formulating effective policies for prudent management of natural resources to achieve sustainable development goals (SDG) by exploring all feasible dimensions and analyzing the patterns and dynamics across various interdisciplinary themes such as social, hydrological, ecological and bio-geo-climatic.

Abstract: Natural Resource Rich Regions (NRRRs) are ecologically and economically vital regions that support the livelihood of people through the sustained ecosystem process involving the interaction among biotic and abiotic elements. Identifying NRRRs, considering spatially ecological, geoclimatic, 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. The anthropogenic activities have been the major driver for landscape dynamics with the largescale land use and land cover (LULC) changes. Unplanned and uncontrolled exploitation of natural resources due to industrial developmental activities has escalated rates of LULC changes that led to ecosystem degradation. Spatio-temporal LULC change information provides insights into affecting factors and their impacts on the landscape. Bidar district has witnessed drastic growth in rural built-up areas and the expansions of the National Investment & Manufacturing Zone [NIMZ], in response to the State’s industrial policy of 2014-19 for industrial development. Supervised machine learning technique - Random Forest (RF) was used to assess land use dynamics. Random forest is an ensemble of decision trees maintaining multi-variance and minimizes the correlation among decision trees, in addition, it is less sensitive to noise and reduction of training. Modeling of likely land use aided in the identification of ecologically fragile areas. CA-Markov model is a dynamic model for predicting LULC changes and can simulate long-term predictions of spatial variation of complex patterns. The current study suggests that there is a need to establish robust systems to frame effective policy and make interventions for the conservation and restoration of natural resources.

Keywords: Land use Land cover (LULC), Forest Fragmentation, Carbon Assessment, CA-Markov, Random Forest, Machine Learning, Eco sensitive Zones (ESZs)
Abstract: Eco sensitive zones (ESZ) or Livelihood Lifeline Regions (LLR) are the vulnerable areas with high sensitivity and fragility based on the environmental aspect, where unplanned large-scale developmental activities can 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 are required to delineate ESZs which will aid in conservation of ecological balance in the environment for planning interventions to ensure sustainable development. This study is focused on understanding the spatial extent of ESZs with the help of landscape dynamics from 1973 to 2021 by implementing Machine learning (ML) algorithms in Chikamagaluru district or the Coffee land of Karnataka, India. Temporal land use land cover (LULC) analyses were carried out using Landsat series data from 1973 to 2021 through Random Forest classifier (supervised machine learning algorithm). The Land cover analysis through NDVI showed decline in vegetation cover by 2.77% due to unplanned developmental activities along with enhanced agriculture and horticultural activities. The land use analysis showed a decline in spatial extent of forest cover of 32.77% in expense of agriculture (6.13%) and horticulture (43.14%) in last five decades. Rapid urbanisation and infrastructural developments have also led to increase in builtup areas by 151.33 sq. km. Analysis of the condition of forests through fragmentation metrics showed that spatial extent of interior forest has decreased from 55.72% to 28.05% in last five decades. As a result, 3068.79 Gg of Carbon has been lost which was evident from carbon assessment of the forest ecosystem through InVEST model. Simulation of the land use in business-as-usual scenario has also been carried out to understand the impact of the current rate of land use transitions in the next two decades, with the help of Markov and Cellular Automata techniques; which showed that the area under agriculture and horticulture is likely to increase to 34.26% and 31.96%, respectively in 2038 and forest would continue to decrease (2038). The weights of all bio-geo-climate-ecological-social variables were aggregated and categorised Chikamagaluru district into 4 zones of ecological fragility where 309 and 410 villages are under ESZ1 and ESZ2 category (highest ecological fragility). The prioritization of ecological sensitive zones or LLRs at disaggregated levels in Chikamagaluru district will aid in planning for sustainable development with conservation of the fragile ecosystems to sustain livelihood of people with the sustenance of natural resources and minimal disasters (floods, land slides, mud slides).

Abstract: Temporal land use and land cover (LULC) information of a landscape provide comprehensive knowledge about the factors affecting the landscape dynamic and their impacts on the ecosystem (biotic and abiotic elements). Accelerating anthropogenic activities leads to the over-exploitation of natural resources and changes in the climate regime. Bellary district in the southern Indian state of Karnataka is known for its rich mineral resources and diverse landscapes. The region has witnessed significant land use changes, primarily due to urbanization, industrialization, and mining activities. These changes have adverse effects on the environment, including loss of biodiversity, soil degradation, and water pollution. The study highlights the significance of using supervised machine learning techniques for the classification of land use namely random forest (RF), support vector machine (SVM), and parametric maximum likelihood classifier (MLC). The performance of these algorithms was evaluated through accuracy assessments. Results reveal that RF has the highest overall accuracy (88.94%) and Kappa value (0.76) compared to overall accuracy, and Kappa of MLC (85.51%, 0.74) and SVM (85.47%, 0.63). Based on this, RF was considered for temporal data analyses, which highlight the decline of forest cover from 2.61% (1973) to 0.74% (2022). The built-up has increased from 0.27% (1973) to 2.43% (2022), and agriculture from 68.21% (1973) to 84.95% (2022). Fragmentation of contiguous forests is evident from the decline in the interior or intact forests from 6.73% (1973) to 2.41% (2022) and the increase in the non-forest areas such as built-up, agriculture, etc. amounting now to 89.81%. The current study highlights the importance of sustainable land use management practices to protect the environment and the need for efficient tools such as supervised machine learning techniques for land use classification and analysis. Simulation and prediction have been performed through the hybrid CA-Markov method for 2030 and 2038. The predicted results show that the built-up area will increase considering the current rate of land use change. NRRRs are prioritized in the study region based on the biological, ecological, geo-climatic, hydrological, and social aspects. A weightage matrix has been used for the classification of NRRRs into four regions NRRR 1 and NRRR 2 (highly sensitive and any alterations are not permitted), NRRR 3 (moderate sensitive and developmental activities are allowed with stringent environmental norms), and NRRR 4 (less sensitive and suitable for the development activities) based on conservation aspects. Prioritization of NRRRs helps in a systematic framework for the sustainability of natural resources with the appropriate conservation strategies through the involvement of decision-makers and local stakeholders.
