ANALYSIS OF GREEN CAMPUS POTENTIAL IN PARTS OF ARID ZONE USING HYDRO-LANDSCAPE TECHNIQUE

India is a massive country with wide range of climatic condition in terms of rainfall, temperature, depth of ground water level, soil cover etc. These variations may affect the ground cover such as in Tropical and sub-tropical zone - the scarcity of rainfall and the micro-climate becomes conducive for the growth of vegetation where as in arid zone such as Gujarat and Rajasthan- the soil and water are not very favorable, as a consequence scarcity of vegetation. The current view on climatic analysis of India clearly indicates that the development of Green Campus in arid climate zone will be a challenging issue especially in the field of landscape architecture. The basic issues related to arid climate is depletion in the depth of ground water level condition by virtue of which the vegetation in general is decreasing. In this way, the hydro-landscape technique will be useful for Green Campus development in part of arid zone with selective areas conducive to develop of soil moisture content. The present study is with the application of hydro-landscape technique to develop the green campus in arid climate in order to establish the area with conducive environment.

Etiological Study

Shanghai is situate in the sub-tropical zone and has a climate of wide variation of temperature, but is broadly tropical during the summer quarter and temperate for the rest of the year. Lying on the alluvial flat of the Yangke delta the conditions of soil and sub-soil are uniform in all parts of the Settlement. The ground water-level is about five feet below the surface.

Plant Herbivore

1. Silicon mediated plant–herbivore interactions have gained increasing recognition and have now been studied in a wide range of species. Many studies have also considered accumulation of Si by plants as a process largely driven by geo-hydrological cycles. 2. To identify factors driving the water - plant Si - herbivore nexus we analysed the concentration of Si in fibrous tussock sedge (Carex appropinquata), the population density of the root vole (Microtus oeconomus) and the ground water level, over 11 years. 3. The largest influence of autumn Si concentration in leaves (Sileaf) was the level of the current year’s ground water table, which accounted for 13.3% of its variance. The previous year’s vole population density was weakly positively correlated with Sileaf and alone explained 9.5% of its variance. 4. The only variable found to have a positive, significant effect on autumn Si concentration in rhizomes (Sirhiz) was the current year spring water level explaining as much as 60.9% of its variance. 5. We conclude that the changes in Si concentration in fibrous tussock sedge are predominantly driven by hydrology, with vole population dynamics being secondary. Our results provide only partial support for the existence of plant-herbivore interactions, as we did not detect the significant effects of Si tussock concentration on the vole density dynamics. This was mainly due to low level of silification of sedges, which was insufficient to impinge herbivores. Future studies on plant–herbivore interactions should therefore mainly focus on identification of mechanisms and conditions allowing plants to accumulate silica at the levels sufficient to act as an anti-herbivore protection.
