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.

Keywords: Landscape dynamics, Land surface temperature (LST), Urban heat island (UHI), Spatial interrelationship, Urban thermal field variance index (UTFVI)
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: The present study aimed to assess the effect of water absorbent polymers application on the survival, growth performance, biomass and leaf physiological characteristics of short rotation i.e., Melia dubia and long rotation tree species i.e., Dalbergia sissoo. The hydrogel was applied in powdered form before planting the seedlings in soil pits of 50x50x50 cm2 volume at concentrations of 0,25,30,35, 40, 45, and 50 g/pit. A significant increase was recorded with increasing the amount of hydro gel for both species. In M.dubia, treatment T2 (30 gm/pit) was found best for growth and biomass parameters and lowest was in control. The nitrogen (N), potassium (K) and physiological parameters such as relative water content (RWC) and membrane stability index (MSI) were also recorded higher in T2 (30gm/pit), while phosphorus (P) was in T3 (35gm/pit) treatment. Total carotenoid was recorded maximum for both T2 (30 gm/pit) and T3 (35 gm/pit).Chlorophyll content increased with increasing dose of hydro gel application and the maximum was in T6 (50 gm/pit), while TSS showed a reverse pattern and the maximum was in T1 (25 gm/pit).In case of long rotation tree species i.e., D. sissoo, growth and biomass was in general higher in treatment T3 (35 gm/pit) and minimum in control.

Abstract: The present study deals with the taxonomic exploration and phenology of some poisonous plants found in the different forest patches of Belaphari forest region of Jhargram district, West Bengal. Phenology is the morphological expression of physiological activities of the plants. Plant phenological study has significance because it not only provides knowledge about plant pattern but also provides the idea on the effects of environmental and selective pressure on flowering and fruiting behaviour. The phenological study of selected poisonous plants depends on the observation, interpretation and recording of the timing of their life history events. During this time different phenophases such as vegetative growth, flowering and fruiting time, seed germination, ripening of fruits and leaf senescence were observed timely in every month. Among six plants maximum plant species showed germination during June to July. Maximum flowering and fruiting times are September and October to December.

Abstract: An experiment was conducted to study the effect of sewage sludge application and its combination with chemical fertilizers on growth and uptake of macronutrients by poplar nursery. Sixteen treatments namely control, 50%RDF (recommended dose of fertilizers), 75% RDF, 100 % RDF, 5 t/ha ss (sewage sludge), 10 t/ha SS, 15 t/ha SS, 50% RDF+5 t/ha SS, 50%RDF+10 t/ha SS,75%RDF+5t/haSS,75%RDF+10t/ha SS,75%RDF+15 t/ha SS were applied in three replications.The RDF for poplar nursery was 125, 150 and 75 kg/ha N,P705 and K201 respectively .Plant height and collar diameter were the highest at 100 % RDF+10 t/ha SS (409.1 cm and 27.88 mm, respectively) which were statistically similar with 50%RDF+15 t/ha SS, 75% RDF+10 t/ha SS and 75%RDF +15 t/ha SS.Dry weight of soot, root and litterfall, and concentration and uptake of macronutrients (N,P,K, Ca, Mg and S) were significantly higher at 50% RDF +15 t/ha SS and 75%RDF +10 t/ha SS than other treatments. Build-up of macronutrients in the soil was highest at 100 % RDF +15 t/ha SS. It is suggested to apply 50% RDF +15 t/ha SS or 75%RDF +10 t/ha SS for getting good growth of poplar nursery and for saving of fertilizers to the tune of Rs, 7041/ha or Rs 3520/ha, respectively from Rs 14082/ha at 100%RDF.

Abstract: Quercus leucotrichophora (bank oak) predominates the mid-altitude temperate forests of the western Himalayas, serving as keystone species meticulously examines the impact of forest size and managemetn practices on the physicochemical properties of soil within oak-dominated forests of the Garhwal Himalaya, Uttarakhand. Four sites-comprising two large reserve forests, one diminutive reserve forest, and one small community managed forest-were meticulously selected across the Pauri and Rudraprayag districts. Soil samples were taken from five distinct depths (0-100 cm) and subjected to analyses for moisture content, bulk density (BD), soil organic carbon (SOC), texture, water holding capacity (WHC), and pH, Rigorous statistical analyses, including ANOVA, Turkeys
's HSD, correlation matrices, and Principal Component Analysis (PCA), unveiled significant disparities in soil parameters across both sites and depths. These findings illuminate the significance of forest size and management in regulating soil health, hydrological balance, and carbon sequestration, thereby offering critical insights for sustainable forest conservation and climate resilience within Himalayan ecosystems. The present study illustrates that reserve forests are more effective in regulating soil organic carbon as ecosystem service than their smaller community-managed counterparts.

Abstract: The management of forests is essential for the conservation of biodiversity and climate change. The present study aimed to anticipate how forest composition, regeneration, biomass production, and carbon storage vary in altitudinal gradient in the Jaunpur Range, Mussoorie Forest Division of Garhwal Himalaya. It lies between 30°25.00’-30°33.00’N 8°3.00’-078°15.00’E and represents a temperate forest. A total of 0.1 ha. size 50 sample plots were laid down randomly at each site. Authors recorded 5 different types of forest along the altitudinal gradient. The results reveal that the maximum total Biomass for the pine stand is 198.84 Mgha-1 followed by Oak Stand 70.796 Mgha-1 for Cupressus stand. All the tree species,48% showed poor regeneration, 33 % showed no regeneration, 5 % exhibited new regeneration, 9 % represented good regeneration, and the remaining 5 % indicated fair regeneration at the study site. Quercus leucotrichophora emerged as the dominant tree species at 1, 800-2,000 masl, co-dominant at 1,300-1,500 masl after Pinus roxburghii, showcasing its ability to withstand biotic pressure and exhibit a wider ecological range. The highest tree diversity (H=1.37) was observed at 2000-2200 masl.

Subject: Wild crime and prosecution effectiveness in the state of Uttarakhand
Keywords: Wildlife crime, Illegal wildlife trades, Poaching, Wildlife (Protection) Act, Uttarakhand
Abstract: The authors present the analysis of wildlife offense records for the state of Uttarakhand with especial reference to the frequent victim species and prosecution success. Based on data collected from different forest divisions and police departments they observed variable duration of investigations. Of the 563 wildlife offence cases, 471 were reported by forest department and 92 by Police department of Uttarakhand. Among 333(54%) cases were of Schedule-1, 12 (2%) were of schedule-II, 161 (26%) were of Schedules-III and 11 (2%) were of Schedule-IV species under the Wild Life (Protection) Act, 1972.It was also observed that 66 (11%) wildlife samples were inconclusive,14 (2%) unschedules and 8 (1%) were found to be fake and remaining8 (1%) cases are still pending with wildlife forensics lab, WII, Dehradun in Uttarakhand, conviction rate in respect of arrested offenders was 50%.In Rajaji Tiger Reserve, only 10 offenders were convicted out of 80 got arrested. In cases of police department only 4 offenders got convicted out of 86 being arrested in wildlife seizure cases. The Kumaon zone has demonstrated a stronger performance in wildlife prosecution, where 66 out of 79 cases have resulted in convictions. The wildlife zone demonstrated robust conviction record, where 60 out of the 162 registered wildlife cases have been decided by trial courts with favourable outcomes for the prosecution in 52 cases. The presented data will be useful in understanding the gaps in law enforcement and streaming the follow-up mechanism in the logical conclusion of the associated cases.

Subject: Struggles in Leveraging and commercializing Non-timber Forest products for sustainable livelihoods: A study of the Baiga and Gond Tribal communities in Balaghat District, Madhya Pradesh
Keywords: Non-timber forest products, Baiga, Sustanbale liveihoods, NTFP commercialization, Socioeconomic development, Traditional knowledge
Abstract: Forests are Non-Timber Forest Products (NTFPs), such a fruits, nuts, medicinal plants, and resins, play a significant role in the livelihoods of forest-dependent communities. This study examines the socioeconomic dynamics and challenges faced by the Baiga and Gond tribes in Madhya Pradesh, India, with a focus on NTFP commercialization. The study was conducted in ten villages within the Bhimlat Block of Balaghat District. The research utilized qualitative methods, including in-depth interviews, focus group discussions, and particularly approaches. A total of 168 respondents, comprising both Balga and Gond tribes, were surveyed. The findings highlight that 88 % of the Baiga and Gond tribes, were surveyed. The findings highlight that 88 % of the Biga population relies heavily on NTFPs. The study reveals that while NTFPs are integral to the local economy, commercialization efforts are impeded by poor market conditions, low pricing, post have losses, and access restrictions in proacted areas. The regression analysis examining income through NTFPs in relation to gender, education and age reveals significant disparities and insights. Modern interventions, such as government housing schemes, often fail to align with the cultural needs of the Baiga and Gond tribes, underscoring the need for culturally informed approaches. NGOs and forest departments address these challenges by improving market access, supporting quality maintenance, and providing institutional support. However, a comprehensive strategy is essential, incorporating better market infrastructure, preserving traditional knowledge and integrating gender equity and education. Enhancing NTFP commercialization reseillience and ecological sustainability in forest-dependent communities.

Abstract: Chandrayaan-3 is the third mission in the series of lunar exploration missions of the Indian Space Research
Organisation. The mission demonstrates an end-to-end
capability for safe landing and roving on the lunar surface. The lander was equipped with many sensors for
a safe landing. One of the prime sensors for precise
altitude estimation was the Ka-band radar altimeter
(KaRA). The KaRA is designed to cover a large altitude range of 10 km to 10 m. To ensure its reliability, the KaRA go through an extensive verification and
validation process, including a series of field tests designed to mimic the lander’s expected descent trajectory. These tests used different platforms, such as a
crane, a helicopter, and an aircraft, to simulate various
flight profiles. In addition to field experiments, KaRA
was subjected to hardware-in-loop simulations and laboratory testing. KaRA performed exceptionally well
across all forms of evaluation. The present study discusses the comprehensive field test campaign, the challenges encountered, the outcomes achieved, and innovative strategies employed to enhance the robustness of
the algorithms integral to KaRA operation.
