Subject: Bringing back from the brink: a new initiative to prevent the extinction of critically endangered tree species in the wild
Keywords: None
Abstract: We live in what many consider the Age of Anthropocene, where Homo sapiens has become the dominant species on Earth. Human activities have significantly altered ecosystems, impacting biodiversity and ecosystem processes. The scale and speed of these changes, largely driven by anthropogenic factors, are unprecedented. These include: Land and sea use change; Direct exploitation of species for food, fuel, timber and medicines; Pollution; The introduction of invasive alien species. Furthermore, owing to vastly developed supply chain logistics, what was previously for subsistence and local use has now become a source for the global marketplace1 . Historically, mass extinction events were triggered by natural phenomena like asteroid impacts or volcanic eruptions. However, for the first time in Earth’s history, human actions are causing a mass extinction, where species are becoming extinct significantly faster (the sixth mass extinction) than they have for millions of years before2 .

Keywords: Artificial diet, fall armyworm, mass culturing, Spodoptera frugiperda.
Abstract: Standardising artificial diets for mass-rearing insects in laboratory is crucial for deepening our understanding of insect biology, behaviour and nutritional needs, which are pre-requiste for developing effective integrated pest management strategies. The present study was focused on formulating an optimal artificial diet for the invasive pest Spodoptera frugiperda by evaluating various diet ingredients and their impact on insect development. Out of 32 diet compositions tested, 16 diets supported developments to the adult stage and these 16 diets were further evaluated to identify the best-suited diet. Among these, a diet based on lab lab beans emerged as the most effective for rearing fall armyworm in the laboratory. Larvae fed with a diet of lab lab beans soaked and supplemented with maize leaf powder, excluding Wesson’s salt, achieved the highest larval weight (0.3807 g on the 7th day after hatching), the shortest larval duration (14.47 days), the highest pupal weight (0.2520 g), the shortest pupal duration (10.03 days) and the highest adult emergence rate (94.50%). These results were comparable to the diet of soaked lab beans without maize leaf powder and Wesson’s salt, which recorded a larval weight of 0.2343 g, a larval duration of 15.50 days a pupal weight of 0.2107 g, a pupal duration of 10.25 days, and an adult emergence rate of 93.00. The addition of Wesson’s salt did not significantly enhance growth parameters. Although the diet including maize leaf powder supported the highest adult emergence, its cost and the difficulty of sourcing pesticide-free maize leaf powder make it impractical. Therefore, the diet without maize leaf powder has been standardized as the most efficient and reliable method for producing a large and continuous supply of insects for research purposes. This optimized diet not only ensures the robust growth and development of S. frugiperda but also provides a cost-effective and practical solution for laboratory rearing, significantly advancing research capabilities in pest management.

Subject: Kinetics, isotherms and thermodynamics of Cu(II) metal ions adsorption: an insight into chitosan and bentonite
Keywords: Adsorption isotherm model, adsorption kinetic model, adsorption thermodynamics, bentonite, chitosan, FTIR
Abstract: Chitosan + bentonite modified composite was synthesized to analyse its removal efficiency for Cu(II) metal ions. FTIR analysis done for chitosan, bentonite and the prepared biocomposite of chitosan + bentonite gave detailed information about the active functional group present on the site of adsorbent. SEM-EDS micrographs reflected the distribution and weight percent of elements in the prepared bio-composite with prominent porosity and roughness but after the adsorption of Cu(II), the porosity and roughness of the adsorbent decreased. Freundlich isotherm best fitted to Cu(II) metal ions indicates that the adsorbent surface is heterogenous. The value of the regression coefficient for the Lagergren kinetic model for the adsorption of Cu(II) metal ions was 1 and hence, it has the highest conformity towards the pseudo-first-order kinetic model. Adsorption thermodynamics revealed that it was a spontaneous and exothermic adsorption.

Keywords: Change detection, Google Earth Engine, machine learning, prediction, random forest.
Abstract: Land cover maps help in understanding the spatial and temporal dynamics of a particular area in a given time. The present study was done in the Kolkata Metropolitan Area (KMA) and East Kolkata Wetland (EKW) in India using the machine learning (ML) algorithm of random forest classification and prediction in Google Earth Engine. The ML algorithm was used to classify the land use land cover (LULC) maps of KMA and EKW for 2002, 2013 and 2023. The ML prediction model further used these LULC maps to predict the future land cover map for the year 2033, both for KMA and EKW. A correlation analysis was done between the built-up of KMA and the built-up of EKW to assess the impact of the urban expansion of KMA on the wetlands of EKW. The present study explored the impact of the increase in built-up area on the wetland and it was seen that the built-up of EKW was increasing due to the increase in the urban expansion of KMA. As a result, the wetland is experiencing a decrease in biodiversity and quality of water and soil.

Subject: Reproductive interventions for revitalising the sustainable production of Malabar labeo, Labeo Dussumieri, an indigenous candidate for aquaculture diversification
Keywords: Indigenous fish, induced breeding, minor carp, spawning, Western Ghats.
Abstract: Malabar labeo, Labeo dussumieri is one of the cyprinids, endemic to the Western Ghats, India. The lack of availability of proper captive production techniques and over-exploitation has led to a decline in the population of this fish in its natural habitats. In the present study Malabar labeo were acclimatised to captive conditions and selected brooders were introduced into breeding pools. They were administrated with synthetic hormones for dose optimisation as well as breeding trial experiments. To determine the effective dose for induced breeding, the females were injected with WOVAFH at 0.5 (T1), 0.75 (T2) and 1.0 (T3) ml/kg body weight. The spawning fecundity was 2.2 ± 0.2 lakhs eggs/kg during the peak spawning season. Among the three treatments, T2 (0.75 ml/kg body wt.) showed the best results in terms of egg fecundity (89,560 ± 592), fertilisation rate (94.76 ± 0.57%), hatching rate (90.31 ± 0.68%) and spawn survival rate (85.25 ± 0.54%). The fertilised eggs were round, non-sticky with a diameter of 2.48 ± 0.1 mm, and hatching took place between 16 and 20 h after fertilisation. The newly hatched larvae had an average total length of 4.1 ± 0.2 mm and a weight of 2.7 ± 0.4 mg. The study revealed the potential of producing L. dussumieri under captivity and meeting its demand for farming and conservation

Subject: How do marketing channel choices affect the welfare of paddy growers in Punjab and Haryana
Keywords: Agricultural marketing, farmer welfare, marketing channels, multinomial logit, paddy growers.
Abstract: The marketing channel choices of paddy growers and their subsequent effect on welfare (indicated by quantity, return and prices) are empirically estimated in the study, conducted in the states of Punjab and Haryana. Using data from the third Situation Assessment Survey, the study focuses on households engaged in paddy cultivation. Results reveal that the local market is still the most prominent marketing channel in rural Punjab and Haryana. Around 46% of produce is disposed of through it, and more than 50% of growers opt for the same. There are significant variations in awareness of the minimum support price and the price realized after selling paddy across different categories of land ownership. Government assistance is a major factor in shaping the marketing channel choices. The findings in the study indicate a strong link between marketing channel choices and the welfare of paddy growers. It provides valuable insights into the dynamics of agricultural marketing in India and underscores the need for tailored policy interventions to improve the welfare farmers.

Abstract: Hypertension and diabetes are the two most prevalent non-communicable diseases in India, and their exposure is increasing fast with time. In the present study, an attempt is made to assess its prevalence (P), diagnosis (D), treatment (T) and control (C) in three mutually exclusive groups of individuals aged 30–79 who are only hypertensive (OH), individual with only diabetes (OD) and hypertensive as well as individual with diabetes (HD) and its correlates based on fifth round of the National Family Health Survey (NFHS-5) with the help of chi-square test and multivariate logistic regression. The prevalence, diagnosis, treatment and control (PDTC) rates of the disease among OH were 21.7%, 26.9%, 23% and 10.7% respectively, and it was 11.4%, 17.1%, 16.4% and 5.1% among OD, followed by 9.9%, 24.6%, 22.4% and 3.1% among HD. They also exhibited significant associations (P-value < 0.05) and risks, such that rural (odds ratio (OR): 0.628), and female OR: 0.876) had a lower risk of coexistence compared to urban and male respectively. Individuals who were divorced (OR: 1.137), age group 70-79 (OR: 7.468), smokers (OR: 1.71) and consuming alcohol (OR: 1.100), as well as those overweighed, had a higher chance of HD. In conclusion, addressing these risk factors with association and the geographical distribution of PDTC of HD in India could potentially enhance public health in the region.

Subject: Growth dynamics analysis of cauliflower in Himachal Pradesh
Keywords: ARIMA, cauliflower, decomposition analysis, forecasting, seasonal indices
Abstract: India, one of the top producers of cauliflower (Brassica oleracea var. botrytis) has made a significant contribution to the agricultural, nutritional and commercial value. The present study examines the growth dynamics of cauliflower production, pricing, productivity and area in the state of Himachal Pradesh. It focuses on the Solan district for data on pricing, productivity and output from 2003 to 2020, and on area, production and productivity from 1995 to 2020. The study projects future scenarios and analyses previous trends using statistical tools, such as seasonal indices, decomposition analysis, Cuddy–Della Valle Index (CDVI), compound annual growth rate (CAGR) and autoregressive integrated moving average (ARIMA) modelling. Results indicate that the growth rate in production (8.77%) surpassed the growth in area (6.48%), whereas productivity growth stood at 7%. Despite fluctuations, cauliflower cultivation remains relatively stable, with area expansion being the primary driver of production growth. The optimal ARIMA models for forecasting area, production and productivity were identified as ARIMA (0, 2, 1), ARIMA (2, 2, 2) and ARIMA (2, 2, 1) respectively, suggesting an increasing trend in area and productivity, whereas production is projected to decline. Price growth rates ranged from 4.45% to 7.51%, exhibiting low variation, and seasonal indices revealed higher off-season variability compared to peak season. The selected ARIMA model for price forecasting is ARIMA (0, 0, 1) (0, 1, 2) with drift. These insights provide valuable information for policymakers and stakeholders in the cauliflower market.

Subject: Methodology for assessment of biogas technology usage in the hilly regions of Himachal Pradesh using CART model on survey data
Keywords: Biofuel, biogas technology, classification and regression tree, hilly regions, machine learning, renewable energy
Abstract: Renewable energy, particularly biogas, stands as a pivotal solution amidst global energy challenges, offering sustainable alternatives to fossil fuels. Himachal Pradesh, a mountainous region in North India, exemplifies this shift with a growing network of biogas plants to alleviate energy poverty and environmental degradation. However, the operational success of these biogas plants remains precarious, marked by a significant non-functionality rate. The present study examines 180 biogas plants across Hamirpur and Kangra districts, revealing that 74.81% of these plants are non-operational. Key reasons include inadequate cattle populations, lack of interest and constructional issues. Classification and regression tree (CART) model was used to identify the reasons and found that inadequate cattle population, coupled with socio-economic factors like declining interest and migration were primary barriers to sustained biogas plant functionality. These findings highlight the urgent need for targeted interventions, including technological upgrades and policy reforms, to enhance biogas plant sustainability and foster rural energy resilience in hilly terrains. By addressing these challenges, Himachal Pradesh can harness its rich agricultural resources more effectively, thereby advancing towards a greener and more sustainable energy future and informing policymakers on enhancing biogas technology’s effectiveness in addressing energy poverty and promoting sustainable practices in rural communities

Abstract: The Chandrayaan-3 Pragyaan Rover traversed a path of approximately 101 m on the lunar surface after the soft landing of Chandrayaan-3’s Vikram Lander on 23 August 2023. Experiments were carried out by the two science instruments, namely APXS and LIBS mounted on the rover. A rover traversal path was plotted over the image captured by the Orbiter High Resolution Camera (OHRC) onboard the Chandrayaan-2 orbiter, taken after the post-landing of the Vikram lander. This plot was based on the mobility commands uploaded to the rover through lander. Subsequent opportunities of imaging the landing site by OHRC could not infer the rover mobility path due to poor illumination conditions over the site. However, recently acquired OHRC image had better illumination conditions and the images were analysed for fetching the rover mobility tracks. Since the rover tracks could not be seen directly in the images, they were further processed to find the rover in-place turn locations, as these must have done the maximum disturbance to the regolith. However, these changes could not be clearly detected using some of the conventional methods. Hence, an indigenous technique was adopted to detect these changes. The present article discusses the findings on the possible landmarks left back by the rover mobility and its coordinates on the lunar terrain.

Keywords: None
Abstract: The three-day National Conference of Plant Physiology 2024 (NCPP-2024) was jointly organised by the ICAR-Central Plantation Crops Research Institute (ICAR-CPCRI), Kasaragod, and the Indian Society for Plant Physiology, New Delhi. The theme of the conference, ‘Frontiers in cell to whole plant physiology: bridging science and sustainability’, focused on the latest advancements in molecular, cellular, organelle, and whole-plant physiology and their translation for sustainable production to feed the growing population during the current critical period of climate change. P. V. Varaprasad (Kansas State University, USA), during the inaugural address, spoke about global challenges, particularly the decreasing relative yield gains as an impediment to development. He highlighted ten major innovations, including speed breeding at the genomic level, gene editing, stress-tolerant crop varieties, nutritious and climate-resilient plants, biofortified varieties, above- and below-ground intercropping, agroforestry, perennial grains, and cross-disciplinary approaches that are driving sustainable intensification for climate-resilient agriculture. Collectively, these innovations underscore the pivotal role of plant physiology in ensuring food security, protecting biodiversity and mitigating climate change – essential pillars of global sustainability.

Abstract: A recent article by Naik et al.1 titled, ‘Performance of human–wildlife conflicts compensation scheme in Karnataka, India’ examines the limitations and obstacles encountered by agriculturalists engaged in a reparation programme for human–wildlife clashes in Karnataka, India. Farmers residing in the vicinity of the Bannerghatta National Park faced setbacks and deficiencies when it came to obtaining reimbursement for agricultural losses and livestock fatalities. The initiative was scrutinized for its insufficient coverage of damages, bureaucratic processes, and the absence of farmer participation in loss assessment. Examination unveiled undervaluation of reimbursements, delays in disbursement, elevated transaction expenses, disregard for market fluctuations, and difficulties in quantifying harm inflicted by wildlife. Suggestions include revising compensation protocols, enlisting experts for loss evaluation, settling land conflicts and using online governmental resources for effective compensation allocation

Abstract: Sustainability is one of the major challenges facing humanity in the current era. Consequent to the uncontrolled/ unfocused developments and the rapidly changing climate (in climatic time scales), which is rapidly approaching the tipping point, humanity is facing increasing challenges in sustainability. Because of this importance, several articles addressing this issue have been repeatedly appearing in this editorial. Increasing urbanisation is a global phenomenon. Currently, a large fraction of the global population lives in urban regions. It is expected that the urban population will be two-thirds of the global population in the next two decades or so. Urbanisation has several advantages. It facilitates easy access to better infrastructure, habitat, better facilities (access to essential daily needs for living, including food, water, mobility, communication and health care), access to better education, better health interventions, and better job opportunities
