Coastal zones are dynamic interfaces of land and water of high ecological diversity and critical economic importance. The boundaries, shape and size of this coast change constantly under the influence of both natural and anthropogenic factors. The study area, Tupilipalem is one of the proposal sites for constructing a major port, to be named Dugarajapatnam Port, along the east coast of Andhra Pradesh, India.

Plants with rising atmospheric carbon dioxide (CO2) level in the environment may change their nutrient demands to sustain growth. The mechanisms concerning iron dynamics in plants under the interactive effect of salinity and elevated CO2 are poorly understood. This study examines the effects of long-term as well as short-term growth at elevated CO2 and salt on iron deficiency-associated molecular responses of Porteresia coarctata through analysing the transcript expression of iron deficiency-responsive genes in the leaf tissue.

The objectives of the Winter Fog Experiment (WIFEX) over the Indo-Gangetic Plains of India are to develop better now-casting and forecasting of winter fog on various time- and spatial scales. Maximum fog occurrence over northwest India is about 48 days (visibility <1000 m) per year, and it occurs mostly during the December–February time-period. The physical and chemical characteristics of fog, meteorological factors responsible for its genesis, sustenance, intensity and dissipation are poorly understood.

Flood hazard causes great loss to lives and properties leading to disturbance in human society. Flood is the single most hydrometeorological hazard causing substantial losses. To gain better understanding of the flood phenomena especially for planning and mitigation purposes, flood risk analysis is often required. For the present study, the middle part of Panchganga river of Kolhapur district, Maharashtra was selected.

While we really have no shortage of women learning science and excelling therein as well as in teaching science, their involvement in ‘doing’ science, in leading and directing scientific investigations is not commensurate with those who train in science. While the small fraction of women in the scientific work force is a reality the world over, the situation in India differs from the West in some respects. In India, the matter of real concern is the precipitous loss in ‘trained scientific women power’ at the postdoctoral level. (Editorial)

The objective of rapid development of rural population in a sustainable manner with a view to bridging the urban–rural divide would require leveraging knowledge and technology in an environment conducive for innovation. The concept of a CILLAGE that incorporates the best of a city in a village is developed with this objective in mind. A CILLAGE is a knowledge-based ecosystem for integrated education, research, technology development and deployment as well as capacity building in rural areas. The focus of research work at a CILLAGE is on regional problems.

This article aims to examine the use pattern and potentiality of livestock farming in the Uttarakhand Himalaya, India. We collected and compared data on livestock population and production in 13 districts of Uttarakhand (2001–14) and noted that number of milching livestock, improved hen and milk production increased during the period. Meanwhile, population of sheep, goat, lamb and indigenous hen has decreased. The study reveals that livestock farming, including cattle, milching animals, goat and sheep has high potential in livelihood sustainability.

The 13th century CE Sun Temple at Konark in Odisha, India, is believed to have been built at the mouth of an ancient river named Chandrabhaga. This mythical river figures prominently in ancient literature, although at present no river exists in the proximity of the Konark Sun Temple. This study investigates the possibility of existence of a ‘lost’ river system near Konark through integrated geological and geophysical exploration in conjunction with historical evidence.

The present study was conducted in 2009–10 with the objective to monitor the effect of restorative soil management practices on biological soil quality. The experiment was initiated in 1995 in a strip–split–split plot design with three replications. Sorghum and castor were grown in two-year rotations.

Inorganic soil arsenic (As) in three soils was fractionated adopting phosphorus fractionation schemes. Among these fractions, iron-bound arsenic (Fe-As) was found highest, followed by aluminium-bound arsenic (Al-As). The freely exchangeable arsenic was relatively small compared to the arsenic held by internal surfaces of soil aggregates. The arsenic fractions exhibited positive correlation with phosphorus content presumably due to the fact that high P in soil releases more arsenic from soil adsorption sites owing to the competition for the same adsorption sites.
