Prof. Shanti Lal Kayastha, who rendered long, exemplary and selfless service throughout his illustrious career of nearly 40 years, in the development and coordination of geography discipline in the country, passed away in Varanasi on 6 January 2018. He was born on 30 March 1924 and had his early education at the famous Government College, Lahore, and later at Aligarh Muslim University. In 1948, he joined Banaras Hindu University (BHU), Varanasi as lecturer. He was the first Indian geographer to undertake the study of river basin as a viable unit for integrated resource development and planning. His remarkable work published in The Himalayan Beas Basin: A Study in Habitat, Economy and Society, is a significant milestone in mountain ecology and resource management.Full Text

In this article, sprawl area of impervious surfaces and their spatial and temporal variability have been studied for Pune city over a period of 19 years, i.e. 1992–2011. Statistical techniques and image classification approach have been adopted to quantify the urban sprawl and its spatial and temporal characteristics. For this purpose, satellite images were obtained from various sensors, viz. Landsat Thematic Mapper and Landsat Enhanced Thematic Mapper Plus. To establish the relationship between urban sprawl and its causative factors, multivariate statistical technique has been used. The determinants of causal factors of urban sprawl such as population, α-population density, β-population density, workforce engaged in secondary and tertiary sectors, road density, and gender gap in literacy collectively explain the 93.09% variation in urban growth. The result also depicts that incessant growth in the built-up area in Pune city has surpassed the rate of population growth. From 1992 to 2011, population in the region grew by 75.40% while the amount of built-up land grew by 227.3%, i.e. more than three times the rate of population growth. To understand the future urban growth of Pune city, a foresight approach is being developed that allows long-term projections. This depicts that by the year 2051, the built-up area in the municipal limits would rise to 212.27 sq. km, which may be nearly 50.0% more than that in 2011 (141.50 sq. km). The vegetative areas, open spaces and areas around the highways are expected to become major targets for urban sprawl due to further increase in the pressure on land.Keywords

India does not have a clear stand on the release and consumption of genetically modified crops (food). The only approved crop is Bt-cotton, which has put India on the global map as a cotton exporting country. Even so, Bt-brinjal is under moratorium and GM mustard is prevented from undergoing commercial trial. All these decisions are not based on sound scientific principles. Activism against has successfully prevented exploitation of a powerful technology that can contribute to India’s food and nutrition security. This article attempts to give a balanced perspective of genetic modification technology as one of the serious options to be considered on case to case basis. Ambivalence will seriously affect India’s food security in the future.Keywords
