Subject: Education for sustainability: curriculum provisions and teaching-learning in India
Keywords: Climate change, classroom observations, education for sustainability, sustainable development, teachers’ understanding
Abstract: The issues related to sustainability are emphasized in policy documents and included in textbooks in India. However, the dismal teaching-learning conditions raise concerns about the quality of delivery to students. Amidst these inconsistencies regarding education for sustainability, the present study sought to examine its existing status in two schools in Bengaluru, Karnataka, India. An interview was conducted and classroom observations made involving 35 teachers in total. The study showed that teachers’ knowledge and attitude about sustainability were limited and non-scientific at times. Knowledge about climate and sustainability was transferred in an exam-centred manner without any focus on developing attitudes amongst the students. Highlighting the role of social experiences and cultural capital of teachers, this study suggests a need for concerted efforts to address their deep-rooted understanding and attitudes regarding sustainability.

Subject: A new optimization approach to enhance seismic performance of lead rubber bearing-isolated steel moment-resisting frames under extreme events
Keywords: Bio-objective optimization, frame structures, ground motions, lead rubber bearings, optimal design, yield strength
Abstract: This study presents an optimal design approach of lead rubber bearings (LRBs) for frame structures. The proposed approach involves a bio-objective optimization problem by maximizing the isolation efficiency along with minimization of peak bearing displacement. Further, a varying weight factor approach is proposed to target multiple performance objectives under different hazard levels of ground excitation. The optimal yield strength of LRBs for the considered frames is selected such that the total deviation of both objectives with respect to their specified limits is within 5%. Finally, it has been demonstrated that the proposed approach is generic in nature and valid for different superstructure flexibility and damping when subjected to ground motions of varying hazard levels.

Subject: Crop coefficient for coffee as a function of leaf area index
Keywords: Crop height, coffee, drip irrigation, evapotranspiration, leaf area index.
Abstract: This study was conducted in an experimental site at the Federal University of Lavras, Brazil, to estimate the single crop coefficient (Ke) for drip-irrigated coffee (Coffea arabica) and provide a mathematical description based on leaf area index (LAI). The cultivar used was Catigua MG-3 planted in May 2007 with a spacing of 2.5 x 0.6 m. The LAI were obtained from the average of plant height and canopy diameter with data derived from bio monthly measurement s between 2007 and 2013.Ke values were determined from crop evapotranspiration (ETe) and reference evapotranspiration (ETo). ETe was estimated from the water balance between the periods of successive irrigation in which there was no precipitation, while ET0 was obtained using the Penman-Monteith equation parameterized by FAO. To describe the relationship between Key and LAI, linear and nonlinear models were used. The logistic model was best for describing the Ke values as a function of LAI. The determined minimum, mean and maximum Ke values were 0.21, 0.57 and 0.80 respectively.

Subject: Quantification and economic valuation of carbon sequestration from smallholder multifunctional agroforestry: a study from the foothills of the Nilgiris, India
Keywords: Biomass carbon stock, multifunctional agroforestry, soil organic carbon total carbon sequestration
Abstract: Agroforestry is widely recognized for its role in climate change mitigation and adaptation. However, carbon sequestration and a marketable carbon value of small-holder agroforestry systems in India are poorly documented. Therefore, the present study was carried out to quantify carbon stock in a circular-shaped multi-functional agro forestry (MFA) divided into four equal quadrates. It comprises 24 different tree species and 8 intercrops, mainly established to provide daily income to small and marginal farmers. A non-destructive method was used to assess biomass carbon stock. Soil core samples collected from 0 to 60 cm depth were analysed to quantify soil organic carbon (SOC) stock. Results revealed significantly higher biomass and carbon stock in the following order: Neolamarckia cadamba>Melia dubia>Lagerstroemia parviflora>Dalbergia latifolia>Tectona gransis. Duncan’s multiple range test revealed significant differences in the multi-utility circles (P<0.001). The total change in SOC stock was 11.55 Mg quadrat-1, but the difference was insignicant in different soil depths. The results indicated that the total carbon sequestration and CO2e from vegetation were 2.23 and 9.23 tones respectively. Similarly, CO2e from the soil were 42.37 Mg quadrat-1 respectively; the highest contributions were from quadrat II and Quadrat IV of MFA. By taking into account profitability and incentives to smallholder farmers, the total marketable carbon revenue of MFA was calculated and US $ 206.40.

Subject: Soil organic carbon variation under sub-tropical forest of Himachal Pradesh, India
Keywords: Anogeissus latifolia, carbon sequestration, Pinus roxburghii, soil organic carbon, sub-tropical forest.
Abstract: It is important to estimate soil organic carbon (SOC) content of natural forests for an understanding of the Himalayan ecosystem. In this study SOC concentration was evaluated at three different soil depths (0-0, 10-20 and 20-30 cm) under Anogeissus latifolia (site 1) and Pinus roxburghii (Site II) forest stands in Himachal Pradesh, India.SOC (%) in these forests ranged from 0.37% to 2.20% up to 30 cm soil depth and was higher at site 1 compared to site II. Tree density was also moisture at site I than site II. The present study shows that the tree species can influence SOC of the forest ecosystem, but other environmental parameters such as soil type, moisture and pH are also responsible for changes in the soil carbon sequestration potential. Carbon sequestration in the study area showed significant contribution in minimizing the increase in carbon dioxide in the atmosphere and improving soil quality.

Abstract: How does Nature, the virtuoso chemist, assemble a mineral, an inorganic crystalline compound with a specific composition? How does one account for the final assembly of a crystal hydrate observed through an X-ray lens? Chemical insights into the aggregation of molecules resulting into simple salt hydrates still evade experimental and theoretical studies. This article gives a perspective of how Nature dictates the structural landscape of MSO4-H2O in terms of supramolecular aggregation between the molecular species {M (H2o) 6}2+, SO42- and H2O interacting at supersaturation through H-bonding and subsequent coordination forces.

Subject: Transitions in traditional dwellings
Keywords: Transitions, traditional dwellings
Abstract: A dwelling, while providing shelter, reflects the identity and individually of its occupant(s). Traditional architecture evolved with time, catering to the needs of the inhabitants, adopting local materials and in harmony with the prevalent climate and environment. Growing aspirations and global pressure drive transitions in this transitional fabric, pushing towards modern construction practices. For traditional societies in Asia and Africa with a large rural population, transitions have serious local and global impact, including loss of traditions, increased material and energy demand, and contribution towards climate change. This article reviews transition in dwellings in rural settlements and makes an effort to comprehend its nature, drivers and consequences. Understanding transitions helps appreciate traditional building practices and design for a sustainable future.

Subject: Potential of integrated approach of zinc fortification in maize
Keywords: Potential, integrated approach, zinc fortification in maize
Abstract: Attention towards the major nutrients than secondary and micronutrients is more for achieving the targeted yields. Zinc (Zn) nutrition plays a pivotal role in plant metabolism and yield potential of maize. Indiscriminate use of high-analysis straight fertilizers coupled with negligible, or no application of organics has resulted in imbalanced soil nutrient status and micronutrients deficiency across the globe, and zinc in particular. Zinc deficiency in human nutrition is widespread, after iron, vitamin A and iodine deficiencies. Nearly 49% of the global adult population does not get its daily recommended intake of 15 mg day-1 of zinc. This is one of the leading risk factors associated with diseases such as diarrhoea and retarded growth contributing to the death of about 800,000 people each year. Negative correlation between irrigation and phosphorus was observed with Zn uptake which leads to the low Zn content in kernels, a major cause of Zn malnutrition among maize consumers.

Subject: Soil organic carbon dynamics in Populus deltoids plantations using RothC-model in the Indo-Gangetic region of India
Keywords: Management practices, Populus deltoids, simulation models, soil organic carbon
Abstract: Soil organic carbon (SOC) change can arise because of changes in land use, land management and climatic conditions. Modelling approach helps in proper choice of management practices for soil carbon build-up. In this context, Roth C is promising model for estimation of SOC changes in different land-use systems. In the present study, RothC was used to predict the development of SOC in Populus deltoids plantation during three rotations in three agro-climatic zones of the Indo-Gangetic region, India. The result reveal that Roth C fairly predicts SOC. Root mean square error for Lower Gangetic Region (LGR), Middle Gangetic Region (MGR) and Trans Gangetic Plain (TGP) was 2.75, 4.94 and 1.30 respectively, while comparing modelled and measured data. Model efficiency was 0.25, 0.36 and 0.89 for LGR, MGR and TGP respectively. The rate of change of measured SOC was 1.0, 1.59 and 1.51 mg ha-1year-1 for LGR, MGR and TGP respectively, whereas the rate of change of simulated SOC was higher, i.e1.16 and 1.89 mg ha-1year-1 for LGR and UGR respectively, and lower for TGP (0.97 mg ha-1yer-1).

Abstract: An experimental was conducted using jamun to assess the physiology of seedless fruit formation. Seedless jamuns have higher content of gibberellic acid (GA3) (0.876 mg g-1) than seeded fruits (0.461 mg g-1) produced in the seedless genotype. Consequently, GA3 at 100 ppm was sprayed over the jamun trees that resulted in 99.5% seedless fruit production, which was higher than the unsprayed control (72.6%). Also, the application of GA, at 300 ppm resulted in 36.4 % seedless fruit formation in the seeded genotype. In corroboration with embryo abortion by GA3, the fruits sprayed with the latter at 100 ppm were analysed for their GA3 content. The results indicated that GA3 content was highest (5.609 mg g-1) in these fruits when compared to control (0.683 mg g-1).

Abstract: Numerous studies have underlined the benefits of cultural services from different landscapes and acknowledge the non-material benefits linking society and nature. However, cultural services form agrofroestry have to been reported. Therefore, the present study was conducted in multifunctional agroforestry (MFA) comprised of 24 tree species and 8 intercrops established at the Forest College and Research Institute, Mettupalayam, Tamil Nadu, India. Four workshops were conducted and a total of 105 respondents were asked to fill two sets of questionaries regarding their perception of cultural ecosystem services in MFA. Among the selected components, education services in MFA. Among the selected components, education and scientific knowledge (.90ranked first, followed by relaxation (.86 and walking (0.84). Results from principal component analysis revealed that three components, viz. relaxation, education and scientific knowledge, and inspiration accounted for 56.60^ of the variance. Respondents willingness to pay was Rs 33/visit on an average and multiple regression analysis indicated that the MFA model was a good fit (R2=0.79) for agrofrestry tourism. The results indicate that MFA provides scope for agrofroestry tourism, which will be an additional source of income for small and marginal scale farmers.

Abstract: The brown plantopper, Nilaparvata lugens (Stal) is the most serious pest rice across the world. It is also known to transmit stundted viral disease: the insect alone are in combination with a virus causes the break-down of rice vascular system, leading to economic losses in commercial rice production. Despite its immense economic importance, information on its potential distribution and factors governing the present and future distribution patterns is limited. Thus, in the present study we used maximum entropy modelling with bioclimatic variables to predict the present and future potential distribution of N.lugens in India as an indicator of risk. The predictions were mapped for spatio-temporal variation and area was analysed under suitability ranges. Jackknife analysis indicated that N.lugens geographic distribution was mostly influenced by temperature –based variables that explain up to 68.7% of the distribution, with precipitation factors explaining the rest. Among the individual factors, the most important for distribution of N.lugens was annual mean temperature followed by precipitation of coldest quarter and precipitation seasonality. Our results highlight that the highly suitable areas under current climate conditions are 7.3%, whereas all projections show an increase under changing climatic conditions with time up to 2090, and with emission scenarios and a corresponding decrease in low-risk areas. We conclude that climate change increases the risk of N.lugens with increased temperature as it is likely to spread to the previously unsuitable areas in India, demanding adaption strategies.
