Introduction
Ghee is the pure clarified butter fat prepared chiefly from cream and/or desi butter (Makhan) to which no colouring matter is added.  Ghee manufacture has great significance and relevance to Indian masses and the dairy industry. Ghee is a very popular product since ancient time and has greater demand during festival and other ceremonial functions where use of ghee in food has been considered to delicacy due to its pleasing flavour and aroma. There are sufficient recorded evidence to prove that the manufacture of ghee originated from India and has been used extensively for religious and dietary purposes since Vedic times. Presently about 28% of total milk production is utilized for manufacture of about 1 million tones of ghee per annum. It is the traditional product with an established market. Cow ghee is golden yellow in colour, and is attributed unique therapeutic value.  The colour of buffalo ghee is greenish yellow due to presence of pigments called billirubin and billiverdin. Ghee is characterized by its pleasant, cooked and rich flavour. The preferred texture is of larger uniform size from grains having non-greasy consistency.

Giant granadilla, Passiflora quadrangularis L. (syn. P. macrocarpa M.T. Mast.) is the largest fruit in the genus Passiflora. With more than 450 species, Passiflora is the most important genus of family Passifloraceae. It is further divided into 24 subgenera (Killip, 1938). Most of the species producing an edible fruit belong to subgenera Passiflora and Tacsonia. Many species have ornamental interest because of unique and spectacular flowers, or are used for their sedative, antispasmodic, antibacterial, and insect-resistant properties.

The main damage done by the caterpillar of this pest is to bore holes in the pseudostem and to plug it with excreta, causing dead hearts. Larva is pale greenish with pinkish tinge and dark head and has fine hairs on the body with a pro thoracic shield. Adult is a medium sized moth, pale yellowish with small black spots on the fore and hind wings.

Management involves spraying dimethoate or malathion 1.5 ml/lit or phosphamidon 0.75 ml/lit of water. This is mainly intended to manage the adults flying in the crop canopy and the first instar caterpillars that are seen on the outside of the plants and before thsy enter the pseudostem. The spray has to be given at the very first spotting of dead haearts.

English name : Ginger
Botanical name : Zingiber officinale Rosc.
Family : Zingiberaceae
Chromosome number : 2n = 22
Centre of origin : South East Asia
Ginger of commerce is the rhizome derived from Zingiber officinale. This plant is an herbaceous perennial but usually is cultivated annually. Belonging to the family Zingiberaceae, it is known as Adraka in Sanskrit and Adrak in Hindi. Ginger contains 6.5% oleoresin, commercially known as Gingirene, extracted from ground ginger using solvents. The composition of dry ginger includes 10.85% moisture, 1.8% volatile oil, 19.6% water extract, 6.0% cold alcohol extract, 53% starch, 7.7% crude fibre, 12.4% crude protein, 6.64% total ash, and 0.14% acid-insoluble ash. The volatile oil is a pale yellow liquid with a warm, spicy, sweet, aromatic fragrance and a pungent taste. Its primary constituent is zingiberene, a sesquiterpene, while its pungency is attributed to zingerone. Ginger is known to contain around 200 different volatile compounds.

1. INTRODUCTION

Ginger (Zingiber officinale Rosc.) is a perennial herb and the economic part is underground stem (rhizome), which is used as a spice. It is native to tropical South-East Asia, introduced into the West Indies, African countries and other tropical belt of the world. The ginger rhizome is harvested between 6 and 12 months after planting and used as spice in the fresh condition,  peeled and split dried or powedered forms. Ginger is utilized widely as a spice, for pickles, candies and as a medicinal herb. The anti-inflammatory and anti-nausea qualities of ginger have applications in the pharmaceutical industry. Ginger and supplements derived from ginger have received attention for the treatment of chronic inflammation. Administration of ginger has resulted in decreased symptoms of rheumatoid arthritis (Srivastava and Mustafa, 1992) and gingerol (a component of ginger) has been reported to have anti-inflammatory actions (Kiuchi et al., 1992; Tjendraputra et al., 2001).

Ginger is used extensively as a spice in cuisines throughout the world. Ginger belongs to Zingiberaceae family and an English botanist William Roscoe (1753-1831) gave this plant the name Zingiber officinale in the year 1807. The name of the genus Zingiber derives from a Sanskrit word denoting “horn shaped” in reference to the protusions on the rhizomes (Ghosh et al., 2011). It is an oldest rhizome widely domesticated as a spice where the edible part is the swollen underground stem or rhizome. The Zingiberaceous plants have strong aromatic and medicinal properties and are characterized by their tuberous or non-tuberous rhizomes (Chen et al., 2008). Ginger is a medicinal plant that has been widely used all over the world, since antiquity, for a wide array of unrelated ailments including arthritis, cramps, rheumatism, sprains, sore throats, muscular aches, pains, constipation, vomiting, hypertension, indigestion, dementia, fever and infectious diseases (Ali et al., 2008). Ginger has direct anti-microbial activity and thus can be used in treatment of bacterial infections (Tan and Vanitha, 2004).

INTRODUCTION

The Ginkgo tree (Ginkgo biloba) is the only living representative of the order Ginkgoales, a group of gymnosperms of the family Ginkgoaceae. Ginkgo tree can live for as long as 1000 years and has been present for over 250 million years (“Living Fossil”). The name Ginkgo is believed to have come from the Chinese word sankyo or yin-kuo, meaning “hill apricot” or “silver apricot”. The species name “biloba,” meaning two lobes, refers to the unique twolobed, fanlike leaves. Ginkgo has been used as both food and medicine for thousands of years. It is the only tree to have survived atomic blast in Hiroshima (Singh et al., 2008).Seeds of Ginkgo were recorded in the early Chinese records on herbals as a medicine.

G. biloba extract (GBE), is the extracts of Ginkgo leaves, and is available as filmcoated tablets, liquid formulations or injectable in markets of Europe and America.

Standardized extract of the leaves of the G. biloba, labeled EGb761, is one of the popular herbal supplements. GBE has been used in traditional Chinese medicine for centuries for treating circulatory disorders, asthma, tinnitus, vertigo, and cognitive problems. Currently, GBE is among the most commonly taken phytomedicines globally, and is approved in Germany for treatment of cerebral insufficiency (memory loss associated with Alzheimer, vascular or multiinfarct dementia) and conditions such as, tinnitus (ringing in the ears), vertigo and intermittent claudication that results in poor circulation (Mohanta, 2012).

Abstract

The sustainable management of plant genetic resources is of great concern as increasing population and rapid technological strides are putting enormous pressure on this country’s nutritional and food security. Management of plant genetic resources at national level generates and uses enormous data and analysis of these data is crucial to the effectiveness of PGR management process and can add significantly to the value of genetic resources. A GIS is a database management system that can simultaneously handle data representing spatial objects and their attribute data. GIS allows us to view, understand, question, interpret, and visualize data in many ways that reveal relationships, patterns, and trends in the form of maps, globes, reports, and charts. It can play an important role in the management of large and complex PGR datasets. The article analyses the potential uses of GIS in plant genetic resources management in India covering various activities such as germplasm exploration and collection, characterization and evaluation, plant health management, documentation and conservation.

Abstract

The study area falls in the southern part of the Indian Peninsular comprising hard crystalline rocks of Archaeozoic and Proterozoic Era. In the present study, the GIS based 3D visualizations of gravity, magnetic, resistivity and topographic datasets were made and therefrom the basement lineaments, shallow subsurface lineaments and surface lineaments/faults were interpreted. These lineaments were classified as category-1 i.e. exclusively surface lineaments, category-2 i.e. surface lineaments having connectivity with shallow subsurface lineaments and category-3 i.e. surface lineaments having connectivity with shallow subsurface lineaments and basement lineaments. These three classified lineaments were analyzed in conjunction with known mineral occurrences and historical seismicity of the study area in GIS environment. The study revealed that the category-3 NNE-SSW to NE-SW lineaments have greater control over the mineral occurrences and the N-S, NNE-SSW and NE-SW faults/lineaments control the seismicities in the study area.

Abstract

The time-transgressive changes in the landscape architecture of the Rameswaram island located in the semiarid tract of southeastern India, was animated using ARC/INFO GIS. The animation has shown that the Rameswaram island has evolved through an interplay of tectonic. fluvial, marine and aeolian activities and that the Aeolian activity was accentuated during 1921-1990 A.D

Abstract

Runoff from rainfall is an important component of the hydrological cycle. Estimation of runoff is critical for the design of hydrological structures and drainage systems in watersheds. Different soils, land use, and water management practices affect runoff differently. In real watersheds, land use, soils and weather conditions vary spatially over the geographical area of the watershed leading to spatial variations in runoff. Also, most watersheds form a part of larger drainage basin or a large watershed consisting of several such subwatersheds. Each subwatershed is hydrologically connected to the other subwatersheds of the basin. A comprehensive GIS based decision support system (DSS) for estimation of runoff that includes the spatial variations in rainfall and natural resources is presented. The DSS is developed as a deployable application by integrating independent GIS layers of watershed features created in ArcGIS with MapObjects in VB, for a case study watershed - the KK3 watershed in Mahbubnagar district of Andhra Pradesh, India. The DSS generates thematic maps of spatial variations in runoff on individual rainy days for the subwatersheds.

This chapter explains how natural disasters are major catastrophic events, which are often aggravated by human intervention, resulting in adverse conditions affecting both natural resources and human habitats. Though drought is as disastrous as any other geohazard, it differs from other geohazards such that it is a ‘creeping phenomenon’, making its onset and end difficult to determine. Only a continuous monitoring of critical parameters ranging from crop failure to joblessness and shifting population, etc, could indicate drought in an area. In this chapter, we demonstrate a GIS based drought forecasting and monitoring model taking Gubbi Taluk of Karnataka as a case study. The approach includes creation of a spatial database of 17 critical parameters and their integration in GIS environment by developing a suitable rating and ranking scheme for the generation of drought severity map. The results have shown that drought could be monitored with the studied parameters and if suitable remedial measures are implemented, their effectiveness could also be monitored with this GIS model.

INTRODUCTION

India is a large country in terms of geographical area, exhibiting greater agro-climatic variation. The country is susceptible to several natural disasters, which are a major constraint to developmental activities. 

INTRODUCTION

Coastal zones are always dynamic and active, because of the multivariate morpho tectonic and morpho dynamic processes, viz: tectonic, fluvial, marine and aeolian which act in varying degrees and duration along the coasts. As these geomorphic / morpho dynamic processes act in varying permutations and combinations in different segments of the coasts, the land - ocean interactive phenomenon vary greatly in time and space, which in turn frequently and dynamically alter the coastal environment, and cause fragility to the coastal ecosystems. Further, as the coastal zones act as the junction between the Continents and the oceans, even mild earth movements exhibit exemplified expressions in land - water distribution pattern along the coasts. The green house effect and the much apprehended sea level rise and the disasters like cyclones also contribute in their own way in accelerating such land - water distribution / land - ocean interactive phenomenon.

Abstract

The emergence of Remote Sensing and GIS technologies has substantially eased the problems of groundwater targeting in hard rock aquifer systems. Proper utilization of these can provide more vital information in managing such scarce resource. In this context, a new technique of GIS based visualization of groundwater levels of different periods (1985- 1990 -1995) was attempted for a part of Western Ghats hill-plain region of Tamil Nadu and various groundwater features viz: ridges, valleys, domes and basins were interpreted. The integration of such groundwater features of different periods and their analysis with structural features provided some newer information on geosystem processes and their interface dynamics with hydrosystems, from which, certain strategies were suggested for better groundwater management in hard rock areas.

Introduction

At human scales, the world consists of objects, events, processes, and a background environment. Cognition is about knowledge: its acquisition, storage and retrieval, manipulation, and use by humans and other intelligent creatures. Cognition includes sensation and perception, thinking, imagery, reasoning and problem-solving, memory, learning, and language. Cognitive structures and process are part of the mind, which emerges from a brain and nervous system inside of a body that exists in a social and physical world. Spatial cognition deals with the cognition of spatial properties of the world, including location, size, distance, direction, shape, pattern, movement, and inter-object relations. GIS design will be largely influenced by spatial cognition.
