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. Clinical trial number: Not applicable.

Abstract: Ecosystems are distinct biological entities characterized by a range of functions. The integrity of the ecosystem is vital for sustaining ecosystem goods and services to support people’s livelihood. Maintaining ecosystem integrity requires ecosystem approaches in managing natural resources considering dynamics due to natural variabilities and anthropogenic activities. Sustainable developmental planning focuses on the efficient and innovative use of regional resources, with an improved understanding of social and environmental interactions. The comprehensive knowledge of a region’s ecological sensitivity/fragility is quintessential for evolving conservation strategies. Ecosystems’ ecological sensitivity refers to ecosystem stability, persistence, resilience, and recovery properties to overcome environmental disasters, which are likely to affect natural landscapes’ character adversely. The ecologically sensitive regions are natural resources-rich zones (NRRZ) endowed with distinct biological elements with geological, physical, and chemical characteristics. Spatial integration of geo-climatic, ecological, environmental, and social variables helps delineate NRRZ for prudent management of natural resources through ecological and conservation planning as per the Biodiversity Act, 2002, Government of India. NRRZ delineation has been done at disaggregated levels (9 km x 9 km grids) considering ecological, bio-geoclimatic, social, and environmental aspects compiled from field and published literature, and prioritization of NRRZ (as NRRZ 1 to 4) has been done through aggregated weightage metric score (of chosen variables per grid). The novelty of the current study is the prioritization of NRRZ at disaggregated levels (grids of 5’ x 5’ or 9 km x 9 km, equivalent to a grid in 1:50000 topographic map of the Survey of India) and also the decentralized governance unit- Panchayat through the integration of diverse multi-dimensional bio-geoclimatic, environmental and social factors. The strength of NRRZ is the replicability for prudent management of natural resources and real-world conservation governance. 32% of the state’s geographical area was depicted as a high-resource region under NRRZ 1 and 2, which needs to be conserved with stringent regulations. Prioritizing regions as NRRZ by integrating spatial data (land cover) with location-based attribute information would strengthen regional decision-making.

Abstract: The landscape consists of a mosaic of interacting ecosystem elements, which maintain stability and aid in sustaining crucial services. Unplanned developmental activities leading to the transition of pervious surfaces into impervious/paved surfaces have significant implications for the urban climate, mainly through the phenomenon of urban heat islands (UHIs). Changes in landscape integrity could be quantified through land use (land cover) assessment and urban heat island effect through spatial computation of land surface temperature (LST). The current research uses multi-resolution remote sensing data to evaluate UHIs with landscape dynamics and assess the complex spatial interrelationships in heterogeneous urban landscapes at micro-levels. The composition of pervious and impervious surfaces at the micro-level plays a pivotal role in regulating thermal comfort. Landscape configuration at microlevels, predominantly barren (C1 class) and urban (C2 class) areas, constitute hotspots with higher temperatures. UHI was mapped through the urban hotspot and Urban thermal field variance index (UTFVI) analysis. Urban hotspot analysis shows the 15.41 km 2 area in the city has a very high temperature. The study provides vital data-driven insights into the complex relationship between urban land use and LST at the micro-level that supports the decision-makers, stakeholders, and public officials in policymaking.

Abstract: Large-scale land cover changes leading to land degradation and deforestation in fragile ecosystems such as the Western Ghats have impaired ecosystem services, evident from the conversion of perennial water bodies to seasonal, which necessitates an understanding of forest structure dynamics with ecosystem services to evolve appropriate location-specific mitigation measures to arrest land degradation. The current study evaluates the extent and condition of forest ecosystems in Goa of the Central Western Ghats, a biodiversity hotspot. Land use dynamics is assessed through a supervised hierarchical classifier based on the Random Forest Machine Learning Algorithm, revealing that total forest cover declined by 3.75% during the post-1990s due to market forces associated with globalization. Likely land uses predicated through the CA-Markov-based Analytic Hierarchy Process (AHP) highlight a decline in evergreen forest cover of 10.98%. The carbon sequestration potential of forests in Goa assessed through the InVEST model highlights the storage of 56,131.16 Gg of carbon, which accounts for 373.47 billion INR (4.49 billion USD). The total ecosystem supply value (TESV) for forest ecosystems was computed by aggregating the provisioning, regulating, and cultural services, which accounts for 481.76 billion INR per year. TESV helps in accounting for the degradation cost of ecosystems towards the development of green GDP (Gross Domestic Product). Prioritization of Ecologically Sensitive Regions (ESR) considering bio-geo-climatic, ecological, and social characteristics at disaggregated levels reveals that 54.41% of the region is highly sensitive (ESR1 and ESR2). The outcome of the research offers invaluable insights for the formulation of strategic natural resource management approaches.

Abstract: Ecology and natural history are thoroughly tangled with an organism's geographic distribution and spatial arrangement. Throughout the nineteenth century, attempts were made to characterize the distribution patterns by considering microclimatic factors like precipitation and temperature. In order to gain a comprehensive understanding of ecosystems, it is essential to delve into the complexities not only at levels below that of an ecosystem, such as individual organisms, but also at levels above it over a geographic space. This includes examining landscapes, ecoregions or biomes and extending to a global perspective. Such an approach is crucial for grasping ecosystems' detailed structure and functioning. The inadequate availability of historical and current information regarding the status and distribution of biotic diversity worldwide presents significant obstacles in comprehending global shifts in biodiversity. The current issue (Sahyadri E News, Issue LXL) offers a comprehensive overview of the biodiversity richness in Karnataka through documentation of the spatial distribution of species diversity within various genera.

Abstract: Energy plays a pivotal role in the socio-economic development of a region as it plays a crucial role in improving human welfare, while raising living standards. The demand of energy requirement is directly proportional to the developmental activities coupled with the population. Across the world a billion people still lack access to electricity and about 3 billion rely on traditional fuels such as fuelwood, charcoal and animal waste for cooking and heating (UNEP- 2020). About 80% of India’s energy needs are met by three fuels coal, oil and biomass (IPNG 2021-22, IEA 2021). India is home to more than 240 million households out of which about 100 million households rely on traditional fuels such as firewood, coal, dung cakes etc. as a primary source of cooking fuel (WLPGA, 2020, Ministry of Petroleum and Natural Gas).

Abstract: The Aghanashini, also known as Tadri River has a total length of 181 km. It originates as Bakurhole at Manjuguni near Sirsi in the Western Ghats of Uttara Kannada district. Another source, closer to Sirsi is Donihalla. The streams meet near Mutthalli about 16 km south of Sirsi. The river, winding its westerly way through the Western Ghats leaps down the Ghats at Unchalli as Lushington Falls. Further down, six km from Bilgi it has another smaller fall namely Burde Jog. The river meets the tide at Uppinpatana in Kumta taluk, 24 km upstream in the River. The river in the coastal zone has two towns, Kumta to its south and the ancient temple town town of Gokarna to the north. At Mirjan it widens into an estuarine expanse for the next 13 km length to Aghanashini village in the south towards south of the river mouth and Tadri, a small fishing port to in the north. This backwater expanse is 2-6 km wide and joins the Arabian Sea between two hills one 91 m in height and the other about 122 km high (Kamath, 1985). Aghanashini and Gangavali are two ancient rivers of the planet, springing from the Western Ghats, descending rapidly towards the west coast and meeting the Arabian Sea towards their confluence forming two important estuaries, rich in diversity and endowed with tremendous capacity to support human livelihoods.

Abstract: Wetlands are among the most productive ecosystems in the world, which are land areas saturated or flooded with water either permanently or seasonally. They cover only 7% of the world's land and are found in all climatic zones apart from Antarctica. Globally, around 7 × 10 1 MOU ID: 82ABF100-2F3C-4D28-B3A9-4F2FD165C74D, 28 March 2019 6 to 9 × 10 6 km 2 is estimated to be wetlands (Pant et al., 2003). According to the Ramsar Convention secretariat. (2016), wetlands are “areas of fen, marsh, peatland or water, whether artificial or natural, permanent or temporary, with water that is static or flowing, fresh, brackish or saline, including parts of marine water wherever the depth at low tide does not exceed six meters”. Ramsar convention classified wetlands into five major types: marine, estuarine, lacustrine, riverine, and Palustrine. Marine wetlands consist of coastal lagoons, rocky shores, and coral reefs. Estuarine wetlands include deltas, tidal marshes, and mangrove swamps— lacustrine wetlands associated with lakes. Riverine includes wetlands along rivers and streams, and palustrine wetlands include marshes, swamps, and bogs.

Abstract: Water Quality Assessment is necessary to understand the quality of water, investigate the causes and anthropogenic impacts, and assess the suitability for current use. The decline in water quality and quantity has a great bearing on the social, economic, and environmental status of a region (Ramachandra et al., 2011). Producers (algae, bacteria), primary consumers (zooplanktons and grazers), secondary consumers (small fish), and tertiary (big fish, birds, etc.) consumers make up the trophic structure of wetlands (Ramachandra et al., 2016). Carbon fluxes are dependent on both natural factors like climate, flora, fauna, and microbial communities; water and soil properties, chemical characteristics, and climate (Bansal et al., 2018; Card and Quideau, 2010); and anthropogenic factors like land-management practises or land use patterns, chemical and nutrient inputs from point and non-point sources, and altered hydrological conditions. Changes in land use/land cover (LULC) types are usually accompanied by a large amount of carbon exchange and alter the carbon cycle process by modifying the ecosystem’s structure and function (Li et al., 2022). Carbon sequestration potential is the amount of carbon (C) a wetland can sequester on a given time and spatial scale. It refers to the highest rate of carbon storage in microalgae, macrophytes, or soil (Zhu et al. 2010).

Abstract: Ecosystems provide a wide array of services that are fundamental to the sustenance of both human societies and ecological systems, collectively termed ecosystem services. The supply of an ecosystem service is associated with an ecosystem structure or process, or a combination of ecosystem structures and processes that reflect the biological, chemical, and physical interactions among ecosystem components. These services are integral to sustaining ecological processes, enabling critical environmental functions, and supplying resources essential for the persistence and welfare of all living organisms (Ramachandra et al., 2024). The concept encompasses both material and non-material ecosystem outputs that societies utilise and depend upon, demonstrating the profound interdependence between human communities and natural systems in generating socio-economic value (Verma et al., 2017; Costanza et al., 2014).
