Subject: Trends and insights of agroforestry practices in Madhya Pradesh, India
Keywords: Agroforestry practices, agriculture, agro-climatic regions, horticulture
Abstract: Agroforestry practices in Madhya Pradesh (MP), India existed in the primordial times, which can be evidenced almost in every region of the state; however, the pace of scientific inclusion in agroforestry and its extension is slow. There is lack of priority and limited work has been done related to agroforestry practices, possibly due to the presence of large natural forest area in the state. In the present context, to meet the national target of forest cover and to reduce pressure on nature forest, agroforestry seems to be a viable option as it provides a source of income for farming and tribal communities along with countless environmental benefits. This article provides a review and insight of agroforestry and extent of agriculture, horticulture and agroforestry in MP. It also provides information on diverse tree species under agroforestry systems, a mosaic of tree-crop combinations and horticulture species preferred by the farmers in different agro-climatic zones of the state. The authors have also tried to enlist the efforts of various government initiatives and other agencies involved in the extension of agroforestry in the state. The roles of MP Forest Department, MP Forest Development Corporation and allied Departments of the State in agroforestry and tree planting have also been discussed. Marketing of agroforestry produce, farmers’ involvement in agroforestry practices and identification of key policy constraints of agroforestry in the state have been discussed and critically analysed.

Subject: Potassium in shrink-Swell soils of India
Keywords: Clay mineralogy, fertilizers, mineralogy, potassium availability, swellshrink soils.
Abstract: This article reviews the information regarding potassium (K) status of Indian soils based on research conducted since 1929.The patterns and lacunae regarding potassium consumption in India are also mentioned. The role of minerals in potassium availability vis-a-vis forms of potassium is discussed and elucidated with suitable clay mineralogical evidences. The article also highlights the problems of potassium availability to plants in Indian shrink-swell soils. We have pointed out the inefficiency of the universal method used for assessing plant-available K (1N NH4OAc) in Indian shrink-swell soils, as observed from extensive K response studies. The current practices of assessing only plant-available K is not adequate to detect native changes in soil potassium. This paradoxical situation necessitates revision and revalidation of the existing potassium fertilizer recommendations, which are being adopted since four decades. A holistic research envisaging soil test crop response and mineralogical studies will help in revising potassium evaluation methods in India, leading to judicious fertilizer application by the farmers.

Keywords: Artificial recharge, biodiversity, climate change, water governance, water resources
Abstract: Management of water resources in Indi has been a challenge whose magnitude has risen manifolds over the past 50 years due to a variety for reasons, notably the rising demands and growing environmental degradation. Broadly, most of the challenges in water management in India can be categorized in the following groups: (a) water availability, variability and increasing withdrawals, (b) environment and quality, (c) project constructions, (d) water sharing disputes, (e) water governance and institutions, and (f) challenges induced due to climate and land-use cover changes. Here we discuss each of these challenges in detail. It is suggested that conservation of water and management of variability should be a cornerstone of water resources management in India. This note also suggests remedies to address the challenges and covers new initiatives by the Government of India (GoI).

Abstract: The middle Indo-Gangetic Plain (MIGP) of India covering eastern Uttar Pradesh and Bihar is endowed with rich and diverse natural resources (land, water and environment), but low productivity and income. Rice-based cropping systems have maximum coverage of net sown area (9.64 m ha) in the MIGP. Wheat, mustard, potato, maize and pulses are the major crops grown in rotation with rice. Rice-Wheat system is extensively practised by the farmers of the region. This system requires high inputs in terms of machinery, nutrients, water and agro-chemicals. Unlike the northwestern part of the IGP Trans and Upper IGP), the rice-wheat system of the MIGPs are less mechanized/labour-intensive due to small and fragmented landholdings and resource-poor farmers.

Abstract: The rugged landscape of the Indian Himalayan region elevates the risk of hazard events and holds back socio-economic development opportunities for remote and vulnerable communities. Particularly notable are landslides, floods, forest fires and earthquakes. Recent international assessment of disaster impacts (1996-2015) revealed that India as a whole suffered the fifth largest mortality, especially related to flood events. The 23-24 September 2018 floods which impacted the Beas River water shed in Kullu district,Himachal Pradesh highlight the significant damages (to infra structure and environment), disruption and costs that disaster events inflict upon us.

Abstract: On 19 June 2019, ‘Day Zero’ was declared in Chennai, Tamil nadu, India. The four main water reservoirs had cracked open with dryness-there was no water left in the city. The news shocked and surprised many because as late as 2015, Chennai was flooded and more than 300 lives were lost. These flood and drought disasters in the city did not occur suddenly, rather they happened gradually through depleting groundwater , drying rivers and vanishing wetlands, much like a predator closing in openly visible, yet invisible by its apparent quiescence.
It may appear that we are weak at anticipating dangers, but this is not true. We can easily sense imminent dangers, but this is not true. We can easily sense imminenet dangers that generate visual stimulation. Unfortunately, the signals relayed from the existing water resources monitoring network in the country are shrouded with uncertainty due to spatially and temporally sparse observations. Therefore, while we hear about environmental and water issues, and vaguely sense something is going wrong, yet strong steps are not taken because our minds do not visualize them as imminent dangers.

Abstract: The study presents assessment and potential oceanographic applications of sea-surface temperature (SST), ocean net shortwave radiation (SWR) and chlorophyll concentration (CC) observations obtained from various geostationary platforms.SST and SWR from imager on board Indian National Satellite (INSAT 3D) and CC from Global Ocean Color Imager (GOCI) on –board communication ocean and meteorological satellite (COMS) have been used in the analysis .Relative advantages of high temporal resolution obtained from the geostationary platform compared to polar orbiting platforms are demonstrated. Comparison of INAT-3D SST with observations gives a correlation of 0.85 and RMSE of 0.81 K. These platforms definitely provide a highly reliable source of continuous observations, which is useful in monitoring dynamic oceanic features such as thermal fronts, chlorophyll blooms, air-sea exchange fluxes, etc. on diurnal to daily timescales.

Keywords: Crystal depth, geoid, gravity anomaly, lithospheric plate, satellite altimetry
Abstract: Moho depth or simply, Moho, in general , describes the boundary between the earth’s crust and the mantle and is a very important geophysical parameter. It is also related to the earth’s crustal thickness at any point. Geoid and gravity anomalies derived from satellite altimetry are gradually gaining importance in marine geo-scientific investigations. However, satellite gravity technique is not working over land/continent. So, we need to develop technique like the VMM model which is equally working over land. In addition of generating crustal thickness, it also saves energy to generate Bouguer anomaly over land and ocean.

Subject: Soybean methylation analysis during strontium stress using methylation-sensitive amplified polymorphism
Keywords: Methylation/demethylation, polymorphism, soybean, strontium stress
Abstract: The effect of strontium stress on the pattern and degree of DNA methylation in soybean seedlings was analysed using the methylation-sensitive amplified polymorphism (MSAP) method. The growth traits were inhibited bySrCl2 treatments. A total of 167 loci were determined and evaluated for DNA methylation after different treatments. The level of cytosine methylation initially decreased and then increased with increasing Sr concentration. Methylation was lowest after 10 mmol/l SrCl2 treatment. Strontium stress resulted in a 57.48 % alteration of DNA methylation pattern in 5’ –CCGG-3’ loci. The pattern variation initially decreased and then increased along with increasing strontium concentration. There was a positive correlation between the total methylation and full methylation induced by strontium stress, and weight and length of shoots and roots in soybean. Overall, the changes in the pattern and degree of methylation may be a key regulatory mechanism for soybean adaptation to strontium.

Subject: Impact of observed climate change on the classification of agro climatic zones in India
Keywords: Agroclimatic zones, classification, climatic parameters, climate change
Abstract: The classification of agro climatic zones in India was made in the 1990s for identifying priorities and developing strategies for location-specific and need-based research as well as overall agricultural development in the country. Long-term climatic parameters, particularly temperature and rainfall along with soil and crop information were used for the classification of agroclimatic zones. It has been documented with a fair degree of accuracy that overall climate is changing, particularly with respect to temperature over the Indian region. Thus it is anticipated that in the recent past, climate change may be reflected in the agoclimatic zones as well and ultimately affect the criteria of their classification based on climatic parameters. The objective of the present study is to examine the trends and spatial/temporal variability of temperature, rainfall, rainy days, and heavy rainfall in different agroclimatic zones of the country, which may help in better understanding of the further initiatives on reclassification of agroclimatic zones, if required .Using various long-term gridded data from 1985 and instrumental datasets starting from 1951 to 1980, studies have been made to observe changes in different components of the climatic variables , i.e temperature and rainfall. it has been observed that there are significant changes in temperature and rainfall, both temporally and spatially, across India and there is a definite shift in temperature and rainfall patterns in the recent past compared to 1951-1980.It has also been inferred that there is a need to reconsider the classification of agroclimatic zones in India under the scenario of observed climate changes in the country.

Subject: China’s export evolution in the dynamic global product space from 2000 to 2011
Keywords: Developing countries, export evolution ,foreign trade, global product space, path creation, path dependence
Abstract: China’s massive export trajectory can enlighten many developing countries regarding foreign trade. Based on the ‘product space’ theory, the present study analyses the evolution of China’s export economy from three perspectives: 1) comparative advantage from a longitudinal perspective, and (2) diversification from a horizontal perspective, and (3) location in dynamic global product space from a spatial perspective. Results show that China’s export economy is becoming more diversified and has evolved from a polarized structure to a relatively balanced system. At the same time, China has been moving from a peripheral location to a core place in the clusters of global product space. This study concludes that both path dependence and path creation are important in driving China’s export evolution process.

Subject: Evaluation of superoxide anion level and membrane permeability in the functionally different organs of Triticum aestivum L.exposed to high temperatue and antimycin A
Keywords: Heavy metals, health risk, polycyclic aromatic hydrocarbon, sewage contamination
Abstract: Heavy metals and organic contaminants are reported in sewage discharged sites. Screening and assessment of their toxic concentration in soils of the discharged sites of major cities in Tamil Nadu, India have been carried out in the present study. The major cities included Coimbatore (Ukkadam; U), Madurai (Avanaiyapuram; A), Tiruchirappalli (Rettamalai; R), Nesapakkam (N) and Koyambedu (K) Chennai Corporation. The total aquaregia-extractable concentrations of cadmium, chromium, lead and nickel were measured and found to be highest in U, followed by A, R,N and K. Their potential bioavailabilities were quantified in the following order: Cd-N>U>K>R>A; Cr-N>AK>R>U; Pb-N>K>R;U>A; Ni-N.K>R>U>A. Bioavailable Factor was found to be highest for Cd in U (2.9 %-83%) followed by Cr in N (1.1%-62.3 %) and Ni in (1.70%-52.7%) N. With regard to organic contamination, the major pesticides belonged to 13 organochlorine, 10 organoposphate and 8 synthetic pyethroids reported below detectable concentration. Among the 16 US EPA priorty poly aromatic hydrocarbons (PAHs) only 15 were detected. However, PAHs were found to be less than the permissible concentration for soils less than the permissible concentration for soils (0.3 mg kg-1) in sewage –contaminated sites. The results show that there is potential risk of transfer of heavy metals to higher trophic level of the food chain.
