Subject: Vertical assessment of soil quality in permanent manurial experiment of dryland ecosystem, Tamil Nadu, India
Keywords: Cotton, dryland ecosystem, nutrient management practices, permanent manurial experiment, soil quality index
Abstract: A study was conducted to assess the impact of different nutrient management practices on soil quality in a permanent manurial experiment cotton field established in 1982 at the Agriculture Research Station of the Tamil Nadu Agricultural University, which falls under the dryland ecosystem of Kovilpatti in Tamil Nadu, India. The experiment was carried out in a randomized block design with nine different treatments. The effect of these treatments in different depths (0–15, 15–30 and 30– 45 cm) was compared, and the soil quality index was developed with a total of 27 parameters, including physical, chemical and biological parameters. Principal component analysis was carried out and the principal components with eigenvalue >1 were selected to determine the indicators to be retained in the minimum dataset. The highly weighted variables, viz. field capacity, available water content, cation exchange capacity, nitrogen, phosphorus, potassium, calcium, magnesium, etc. with a variance of 93.57% were retained for MDS. Linear scoring functions were used to transform them into unitless scores ranging from 0 to 1. Three different methods of soil quality were analysed, viz. weighed additive soil quality index (SQIw), additive soil quality index (SQIa) and Nemoro soil quality index (SQIn). In all three methods, the treatment receiving farmyard manure at 12.5 t ha–1 showed superiority in maintaining soil quality.

Keywords: Adaptation plans, climate change, extreme weather events, temperature and rainfall, statistical significance, trends
Abstract: Regional-level studies aimed at identifying and assessing various types of extreme weather events and comprehending their effects on various sectors are crucial. In the present study, we have utilized the RClimDex software to compute the trend in temperature and precipitation extreme events in the Varanasi district of Uttar Pradesh, India, from 1980 to 2018. We employed both Mann–Kendall test and linear regression to test the statistical significance of the computed trend. Out of 13 temperature indices, 8 showed a significant trend while the remaining showed a non-significant trend. The annual mean maximum temperature, warm days, diurnal temperature range and a monthly minimum of maximum temperature had decreased significantly by 0.029ºC, 0.159 days, 0.032ºC and 0.122ºC/yr respectively, whereas cool days and cold spell duration had increased significantly by 0.264ºC and 0.372 days/yr respectively, indicating an increased cooling effect over the study area. Similarly, out of the 11 rainfall indices, only two showed a significant trend, while the remaining showed a nonsignificant trend. The increasing drought over the study area is evident as the number of rainy days and consecutive wet days have decreased significantly by 0.262 days and 0.058 days/yr respectively, with a non-significant increase in consecutive dry days during the same period. The weak negative non-significant trend of a maximum of five consecutive days of rainfall, very heavy rainfall days and total annual precipitation indicate the decreasing trend of floods. This study stresses the development of adaptation plans to overcome the adverse consequences of extreme weather events in Varanasi district.

Keywords: Climate models, freshwater spread, river fluxes, skill score, trend analysis.
Abstract: The large influx of freshwater and mixing of different water masses make simulating salinity challenging for the Bay of Bengal (BoB) region. This study analyses the variability of the simulated sea surface salinity (SSS) using models present in the Coupled Modal Intercomparison Project Phase 6 (CMIP6). We collected data for 37 models from CMIP6 and validated them against the Argo (2005–14) and Aquarius (2011–14) data. Based on the skill scores, we narrowed down our search to one CMIP6 model, viz. CIESM. This model was used to study the freshwater spread (FWS) in BoB during different seasons. We found that the correlation between pH and FWS was appreciable. The CIESM model was then used to project the future trends for 10 years for the tier-1 scenario. The trend analysis of future projections revealed a positive trend in SSP1-2.6, with a decreasing trend in SSP2-4.5 and SSP5-8.5.

Abstract: The implementation of global, modern urban planning principles has influenced India’s new urban planning and development schemes, which are outlined in statutory development plans. This study assesses the level of preparedness of Indian cities to implement these schemes by evaluating the extent to which their development plan policies address global, modern urban principles. The policies were graded for each principle, and the cities were ranked based on their total grade. The study reveals that Indian cities have not fully adopted modern urban principles in their development plan policies, and there are significant variations in the implementation of these principles across different cities.

Subject: Indian Arachnology (order: Araneae) in the 21st century: trends, gaps and future prospects
Keywords: Arachnology, conservation and policy-making, current trend, ecology, future perspectives.
Abstract: Although Indian Araneae research over the last 20 years has provided insights into spatio-temporal diversity patterns, we lack a methodical synthesis of the work, resulting in knowledge blind spots for answering more pressing questions of ecology and conservation for the taxon. In this study, we present a comprehensive review of the status of Indian arachnological research spanning the 21st century. We find a systematic bias in research (>80%) towards inventories and taxonomic descriptions, with little work on aspects of ecology, biogeography and phylogeny, thereby impairing conservation efforts. Compared to global research advancements, much of the Indian data seems to be qualitative with under-documentation from several important ecozones, highlighting an urgent need to initiate systematic research to achieve a more comprehensive understanding of the Araneae fauna of the country for inclusion in conservation and policymaking.

Keywords: Medicinal plants, nominal and real prices, price elasticity, trend analysis, scarcity ratio.
Abstract: Trend analysis helps predict future events based on past time-series behaviour. Therefore, trend analysis of five medicinal plants having high economic value (chilgoza, kala jeera, dhoop, karro and kuth) was done during the period 2011–12 to 2020–21. According to the study, growth rate in real terms was seen only in Dhoop species, while the other species were dribbling due to overexploitation as these were easily accessible to the local population. Growth rate was recorded highest for dhoop (18.37%/annum) and lowest for kala jeera (4.75%/annum). Nominal price elasticity for chilgoza, karro and kuth was greater than one, indicating that their quantity is changing faster than price, whereas nominal price elasticity for kala jeera and dhoop was less than one, demonstrating that these species possess inelastic properties, with their quantity changing slower than prices. In the case of real price elasticity, only kala jeera was elastic in nature in real value terms, while the remaining species were inelastic. Scarcity ratio was found to be positive only for kuth, which indicates that the availability of this species is dwindling in the forests daily. Therefore, it is necessary to educate the local population on how to grow key medicinal plants, and every household that depends on the forests for these plants should be provided with in-depth guidelines on how to continue using them

Abstract: Landscapes are the biological units that sustain a wide array of ecosystem functions. Environmental fragility is the ability to cope with various environmental disturbances that adversely change the character of the natural landscapes (Ramachandra et al., 2018). It is measured by the degree of variation or disturbance in abundance and composition of the ecological variables. The disturbance is measured in terms of impact on the ecosystem (Nilsson and Grelsson, 1995). Delineation of Environmental Fragile Regions (EFRs) is essential to endure biodiversity by integrated management of bio-geo-hydroclimatic-social resources. Environmental fragility assessment helps identify the region's vulnerable status, quantitative and qualitatively, for ecological restoration and management (Nguyen et al. 2018; França et al. 2022). It aids in visualizing and planning for future development without disturbing the local ecosystem by regulating anthropogenic activities through the active participation of all stakeholders of the region (Gadgil et al. 2011; Yang et al. 2018; Ramachandra et al. 2022). The spatial conservation of Environmental Fragile Regions (EFRs) entails interventions based on ecological and cultural dimensions at disaggregated levels. Mapping multiple levels of EFR (with grids prioritized based on the cumulative eco-sensitive metrics score) aids in opting for eco-friendly development measures through effective regional planning strategies with the conservation of sensitive regions.

Abstract: The landscape is an assortment of heterogeneous interacting dynamic ecosystem elements (Ramachandra et al., 2016) sustaining human and other life forms (Wiens, 2002). The diverse lithological, topographical, spatial settings and the interactions among ecosystem elements contribute to the functioning of the landscape resulting in the flow of nutrients, minerals, and energy (Burgi et al., 2007). The landscape dynamics, which could be natural or anthropogenic induced, and unplanned anthropogenic activities result in the imbalance in processes (Farina, 2021). Land use and land cover are the prime factors that aid in gauging the landscape quality and quantity of resources. Land cover can be defined as the earth's physical surface, which consists of a natural environment such as flora, surface water, and soil. Land cover configuration is stated as a combined vision of the existing natural resources and natural processes that are dynamic in nature (Ramachandra et al., 2021). Land use (LU) indicates how a particular land is used for human activity to derive economic benefits (Lillesand et al., 2003). Land use refers to the changes in land cover with human activities for agriculture, industry, housing, and recreation. Land use land cover (LULC) changes significantly affect critical aspects of 'the Earth System's' functioning, for example, contributing to local and regional climate change and global climate warming, impacting the water quality, or increasing soil degradation (Houet et al., 2010). Unplanned developmental activities such as urbanization, agriculture intensification, and overgrazing, leading to deforestation, and subsequent land degradation, have been causing changes in the structure and composition of a landscape (Geist et al., 2006).

Abstract: A landscape is a mosaic of heterogeneous ecosystem elements with dynamic components of biotic and abiotic features, which governs the landscape's health. Land cover (LC) depicts the natural cover on the earth's surface, whereas land use (LU) indicates anthropogenic usage of the land, and assessment of these variables aid in understanding the landscape and interactions (1). The rise in anthropogenic activities including enhanced carbon emissions, has been altering the landscape's natural processes, bio-geoclimatic interactions, hydrological regime, and global climatic alterations (2–6). The unconstrained land use land cover (LULC) changes induce various ecological imbalances such as fragmentation, loss of resource availability, and interrupted environmental planning. Fragmentation is a devastating phenomenon and a conservation challenge that affects habitat integrity induced due to LULC changes in the form of various development projects, the creation of linear corridors, various infrastructure developments, the establishment of industrial parks, and overexploitation resources. Fragmentation of forests contributes to discontinued forest patches of varying sizes, boost biodiversity loss and connectivity, enhances the forest communities' vulnerability, creates a microclimatic environmental gradient, and stimulates invasive species . Assessing LULC changes induced fragmentation helps in addressing habitat isolation and edge effects on the forest patches

Abstract: The landscape consists of a mosaic of ecosystems, driven by the natural and human interactions leading to changes in the physical, biological, and cognitive assets. Landscape dynamics can be understood by assessing land use and land cover (LULC) changes. Land cover (LC) characterizes physical features on the earth's surface (non-vegetation and vegetation). Land use (LU) indicates how a particular land is being transformed for human activities and other economic aspects. Ecosystems maintain dynamic equilibrium provided LULC transitions are within the threshold (Mensah et al., 2019). Assessment of landscape dynamics helps to understand the LU changes, fragmentation of forests, etc., which are essential for the sustainable management of natural resources (Ramachandra et al., 2020a; 2018a). Detailed assessment of LULC patterns acts as a knowledge base, which aids in framing developmental plans and evaluates the magnitude of land conversion and the associated environmental degradations (Tiwari et al., 2021). The dominance of humans with unplanned developmental activities has converted biodiverse-rich landscapes into dense built-up environments that often lack basic amenities and infrastructure. The transition of native forests into exotic monoculture plantations, agriculture, built-up, open areas has altered hydrologic regime, evapotranspiration changes, land surface temperature, and variation in monsoon pattern (Devaraju et al., 2015; Ramachandra et al., 2018b; 2020b; Tran et al., 2021), etc. Landscape health is governed by its structure (vegetation cover, quality, etc.) that decides the functional aspects. The current trends of declining forest cover across the globe through LULC changes are hampering the ability of ecosystems to adapt to changing conditions and thus resulting in the erosion of goods and services (Bellard et al., 2012), which necessitates understanding LULC dynamics through assessment of spatial data acquired through space-borne sensors at regular intervals.

Abstract: The landscape is a mosaic of ecosystem elements, which changes in size, shape, spatial arrangement, and quality of the patches/elements due to the complex, multiscalar processes, which influence the ecosystem's biotic components. The changes in the abiotic and biotic assets of a landscape are referred to as landscape dynamics. Changes in the structure of the landscape will have implications for ecosystem functions and processes. Landscape transitions leading to deforestation in the landscape due to widespread land use land cover (LULC) changes have been acknowledged as prime agents towards contributing to global warming with the enhanced emissions and loss of carbon sequestration potential. LULC changes have been eroding ecosystem services evident from the decline of biodiversity, alterations in the hydrologic regime, etc., which has affected the sustainability of natural resources (Vose et al. 2004; Polasky et al. 2011; Bharath et al. 2013; Vinay et al. 2013; Ramachandra et al. 2021d). This will profoundly impact land surface climate feedback by altering the exchange of heat, moisture, and albedo at local, regional, and global scales. Clearing large-scale forests will contribute to releasing the carbon stored in vegetation and soils by altering their physical and chemical properties, which affects the global climate by increasing levels of greenhouse gases in the atmosphere, decreasing evapotranspiration and hydrological cycle (Ramachandra and Bharath 2019a, b, 2021; Ramachandra et al. 2020a).

Abstract: Humans depend on the environment for their basic needs, such as food, fuel, minerals, water, air, etc. In developing countries, nearly 80% of the labor force is engaged in agricultural or resource-based activities, contributing significantly to the GDP (World Bank 1998, 2001). The dependency on the natural resources, over the years, has led to their degradation and depletion owing to the unsustainable practices involved in their extraction. Burgeoning unplanned development activities to cater to the demands of the increasing population have put tremendous pressure on the natural resources, leading to environmental degradation (Kulkarni and Ramachandra 2009). An increased surge in developmental and technological activities over the last two decades, with no regard to their ecological implications, has led to indiscriminate disposal of wastes (liquid and solid), contributing to the degradation of the natural ecosystems. This has resulted in a substantial and largely irreversible loss in the diversity of life on Earth (MEA 2005). And yet, unsustainable utilization of land and other natural resources persists, despite the increasing understanding of the impacts that human activities have on the environment, (Euliss Jr et al., 2010). Linkages between the health of the environment and the sustenance of humankind make it imperative to maintain a balance considering the carrying capacity of the environment and the availability of natural resources. Conservation of natural ecosystems has long-term benefits for humans in utilitarian terms through their provision of food, timber, minerals, and a variety of valuable resources that have provided the backbone for economic development. Going beyond utilitarian values, natural ecosystems have also been a source for maintaining gene pools, biodiversity, and other potentially useful factors that are of indirect use to humans. Hence, ecosystems’ intrinsic, anthropocentric, instrumental, and relational values should be considered in the policy design and consider resources exploited for human settlement, food, and energy production.

Abstract: Ecosystem condition accounts provide a structured approach for describing ecosystem assets' characteristics by recording and aggregating data describing the dynamics of ecosystem asset characteristics (SEEA EA). Ecosystem quality is measured in terms of its abiotic and biotic characteristics concerning an ecosystem’s composition, structure, and function, which, in turn, reflect multiple values across a range of temporal and spatial scales indicating ecological integrity. Ecosystem condition accounts record the condition of ecosystem assets in terms of selected characteristics at specific points in time and, over time, record the changes to their condition. These changes are mainly due to human activities with economic interventions.
