Abstract: The objectives of this research were to develop and evaluate an approach for object-oriented mapping of banana plantations from SPOT-5 imagery, and to compare these results to banana plantations manually delineated from high spatial resolution airborne imagery. Cultivated areas were first identified through large spatial scale mapping using spectral and elevation data. Within the cultivated areas, separation of banana plantations and other land-cover classes increased when including image co-occurrence texture measures and context relationships in addition to spectral information. The results showed that a pixel size of < 2.5m was required to accurately identify the row structure within banana plantations, which enabled object-based separation from other crops based on texture information. The user ' s and producer ' s accuracies for mapping banana plantations increased from 73 percent and 77 percent, respectively, to 94 percent and 93 percent after post-classification visual editing. The results indicate that the data and processing techniques used offer a reliable approach for mapping banana plants and other plantation crops.

Abstract: The linear pushbroom camera has become one of the most important imaging sensors in today ' s photogrammetry and remote sensing practices. Airborne digital sensors (ADS) or three-line scanner (TLS) imaging system such as the ADS40 from Leica Geosystems and STARIMAGER from STAR-LABO Corporation use the pushbroom technique to collect high-resolution, multi-channel seamless image strips. As we know, the object-to-image coordinate computation serves as a core step during the process of photogrammetric images. However, each scanline captured by a linear pushbroom sensor has six exterior orientation (EO) parameters at the corresponding instant of exposure. The image point coordinates will not be accurately calculated through colinearity equations unless reasonable EO parameters are determined. Therefore, the best scanline search (BSS) has direct effect on efficiency of object-to-image coordinate computation during image processing. This paper addresses a fast BSS method based on the novel central perspective plane of scanline (CPPS) constraits. The search process is simply performed through analytical geometric calculations, which can significantly improve the efficiency of the object-to-image coordinate computation. The feasibility and robustness of the proposed method have been verified using ADS40 and STARIMAGER images. Experimental results show that the proposed method improves scanline search speed considerably with the time cost decreased by nearly 85 percent compared with the traditional methods.

Abstract: Developing countries are being encouraged to diversify their food exports by developing new products and adding more value to existing ones. Adding value to and diversifying food exports depends not only on changing production but also processing systems. The traditional Indian fruits are very rich in nutritional parameters and a variety of by-products can also be prepared from them. This paper describes the importance of some of Indian fruits like Bael, Phalsa, Wood apple and Custard apple. These fruit trees thrive well in stony, infertile and neglected lands and bear heavily without any input. Their bulk use in food industry will improve nutrition and provide variety. with little effort, they can be semi-processed locally for supply to food industry. This can provide employment opportunity to the unskilled but energetic youth. The medicinal values of these fruits have additional attraction and there is a tremendous scope for their further exploration.

Abstract: In recent years the large scale urbanization, industrialisation and associated environmental alteration and its impact on biodiversity pose a threat to human existence through basic necessities, recreation and the ecological functions. It is evident that pollution from various sources particularly from industries has negative impact on environment, irreversible in nature, cause extinction of species, resulting in loss of unique genetic resources of great use. This is a transition period for many developing economies like India, so there is a strong need to strike a balance between industrial development and physical environment so as to reduce the intensity of pollution. In this paper an attempt has been made to analyse the ill effects of industrialisation on the environmental pollution. The central theme of this paper is to highlight the effect of industrial pollution on the quality and status of life. The limits for ambient air pollutants, status of air polluting industries, intensity of sound causing noise pollution in the region of Punjab has been examined.

Abstract: A preliminary checklist of Hypericaceae in Indian sub-continent has been prepared on the basis of primary observations of different taxa belonging to this family in wild habitats and on secondary observations based on examining herbarium specimens and taxonomic literature. In the Indian sub-continent (comprising Bangladesh, Bhutan, Myanmar, Nepal, Pakistan, Sri Lanka and India), the family Hypericaceae is poorly represented with 10.2% of global distribution. The present paper deals with distribution, phytoendemism, possible fossil ancestry, potential , survival threat etc. on existing taxa etc. of Hypericaceae in Indian sub-continent. For better understanding of the species dynamics of Hypericaceae in Indian sub-continent, the present status of phytoendemism has been compared with the data of previous investigations done in the Nineteenth century.

Abstract: Grewia optiva is an important fodder tree in Solan District of Himachal Pradesh. It forms an important component of agro forestry systems in the mid hill region because of its multipurpose use as fodder, fuel and fibre. Its leaves are damaged badly by different insects leading to huge losses of green fodder. The different insect pests found feeding on G.optiva are Mimastra cyanura, Myllocerus setulifer, Apoderus spp. Lygropia obrinusalis, Adoretus bimarginatus etc. These pest take heavy toll of the foliage and results in huge losses to the farmers.

Keywords: Bambusa balcooa, Durability, Dimensional stability, Traditional preservatives, Antishrink efficiency, Weight percent gain
Abstract: The North-Eastern region of India is a storehouse of bamboo, where considerable quantity of bamboo is being used without any systematic treatment or being treated traditionally like water submersion, smoking and baking over fire. Durability of bamboo can be enhanced from 3 to 30 years depending upon the preservative chemicals, bamboo species and end uses. Various inorganic/organic formulations incorporating copper, arsenic, boron, zinc, pentachlorophenol are being used individually or in mixture. The use of arsenic/chromium based compositions and pentachlorophenol is under constant review due to environmental consideration and is slated for phasing out in the future. Hence it may be worthwhile to make a comparative study of the efficacy of plant extracts, traditional and other alternative chemicals like boric acid, phthalic anhydride/maleic anhydride and copper acetate as dimensional stabilizer and anti-termite agents. The dimensional stability of chemically treated (phthalic anhydride) sample in terms of antishrink efficiency (ASE) was increased by 68.80% at the level of 30.81% weight percent gain (WPG) and the ASE of plant extract (Chromolaena odorata) treated sample increased by 42.13% at the level of 18.17% weight percent gain (WPG).

Abstract: Climate change and forests are intrinsically linked. On the one hand, changes in global climate are already stressing forests through higher mean annual temperatures, altered precipitation patterns and more frequent and extreme weather events. At the same time, forests and the wood they produce, trap and store CO2 , play a major role in mitigating climate change. During the course of this study, potential of carbon sequestration, one of the major intangible benefits, was studied for 14 Populus deltoides clones. The carbon content was determined in different parts of trees i.e., bole, bark and branches. The results showed that the carbon content was found in the order: bole>branches>bark. Clone ' WIMCO -22 ' was found the best in terms of carbon stock while WIMCO-42 ' was the poorest one in this respect.
