Green belt land is an open space around bigger cities. The main purpose of the green belt is to protect the land from urban sprawl, and maintain the designated area for forestry, agriculture as well as to provide habitat to wildlife. Green belt offers a number of benefits for population. Areas that are designated as green belt must not be built upon, however, that does not mean that no buildings can be erected in green belt. GREENBELT is a policy and land use designation used in land use/land cover planning. Green belt policy may not work well in all areas and has been a subject of criticism; however, its advantages by far outweigh its disadvantages. The Green belt land covers about 2% of total geographical area in Gulbarga city of Karnataka state. They do not solve the problem related to low forest cover in the Gulbarga District but they significantly improve air quality and help combat a number of environmental problems. During the data collection (43%) of respondents both knew that Green Belts surround city, and valued Green Belts as places to enjoy quiet recreation It is confirmed that Green Belt policy has been highly effective in eco-friendship relation. Green Belts have a role to play in achieving positive land use objectives. The concept of Green Belt also has strong support amongst the general public, even if they do not always understand the full details of the planning policy. These areas could take on an even greater significance in the face of climate.

The study involves survey of amphibian and reptile in and around Gulbarga University Campus. Survey was conducted from Jan 2012 to March 2013. The survey methods involved careful visual estimation of amphibians and reptilian in all the possible habitats present in the study area. The objective of the study included evaluate of species composition, relative abundance and distribution of amphibian and reptile of the chosen area. During survey a total of 16 species of herpetofauna identified belonging to 12 families, which includes 9 species of snakes, 4 species amphibians, 3 species of lizards.

A preliminary survey on earthworm species from north Karnataka region, Gulbarga district, Karnataka state, India, has been conducted from January 2012 to December 2013. Survey was conducted in three regions of Gulbarga district i.e. Afzalpur, Chittapur, and Sedam taluk. Six species of earthworms were identified belonging to four families namely lumbricidae, Octochaetidae, Megascolecidae and Eudrilidae. Eisenia fetida belonging to family lumbricidae, Dichogaster bolaui belong to family Octochaetidae, Polypheretima elongate, Perionyx sansibaricus and Perionyx excavates belong to family Megascolecidae and Eudrilus eugeniae belonging to family Eudrilidae. Among the species, Eudrilus eugeniae does not occur naturally and are produced from external sources for vermicomposting units.

The present study deals with the fish fauna of Kurikotta Bridge Bennithora River, Gulbarga district of Karnataka. The study was undertaken for a period of one year and monthly collections were made from April-2013 to March-2014, in four sites. The result of present study reveals the occurrence of seventeen (17) fish species belonging to five orders. The order Cypriniformes was dominant with nine (9) followed by order Siluriformes (4) Channiformes (2), Mastacembelidae and Osteoglossiformes each with one species.

Carallia brachiata (Lour.) Merr. is one of the soft woody species occurring all along the Western Ghats region of Kundapura, Karnataka, India. The species is considered to be a potent medicinal plant exclusively used against itch and septic poisoning. A study was under gone based on the report of forest department (Karnataka) on mortality of Carallia brachiata. Observation of symptoms on the infected trees and experimental analysis of the samples under laboratory conditions revealed the incidence of Neofusicoccum sp., a first report on Carallia brachiata. This particular Neofusicoccum sp. belongs to Botryospaeriaceae family, and is considered to be an important fungal pathogen associated with tree decline in forest and plantation worldwide.

The avifauna of Gulbarga city was studied for a period of one year. Gulbarga city has got one reservoirs in the heart of the city, the Shree Sharnabasveshwar Lake. The city has well protected by greenery, Gulbarga University Campus, Kapnoor (Industrial area). During the study of three different transects lines, 30 plants species and 42 birds species were observed, in which 35 are resident species, 6 winter migrant and 1 summer migrant respectively. Highest population of Cattle Egret (Bubulcus ibis) and Blue Rock Pigeon (Columba livia) was recorded in this study. The visitors include White-necked stork (Ciconia episcopus), Yellow Wagtail (Motacilla flava) which are found in the study area. According to status of birds maximum (average) numbers of birds were found in highly urbanized area when compared to industrial area, but species wise variation was high in low urbanized compared to that of highly urbanized area.

In the present investigation, primary productivity of Kumshi reservoir of Kalburagi District has been studied for the period of two years (2012-2014). The results reveals that, gross primary productivity of Kumshi reservoir followed an increasing trend through the northeast monsoon season towards summer season, whereas, net primary productivity of Kumshi reservoir is followed a more or less similar trend of increasing towards northeast monsoon season and summer season, while community respiration of reservoir also followed a similar trend of oscillation increasing trend towards summer and northeast monsoon season during the study period.

The cotton leafhopper (Amrasca biguttula biguttula Ishida) is considered to be an alarming insect pest causing both quantitative and qualitative loss in cotton. In situ bioassay studies were done and the role of detoxifying enzymes in conferring resistance to neonicotinoid groups of insecticides in low (MUD), medium (DVG), high (HVR) and very high (GLB) pesticide usage areas of Karnataka were determined. Bioassay studies showed that imidacloprid, thiamethoxam, acetamiprid, thiacloprid and clothianidin registered varying levels of resistance for all the locations studied. The resistance ratio was high in imidacloprid (3.35, 8.57, 9.15 and 12.27 fold respectively) and the lowest in dinoferuran (1.86, 5.13, 6.71 and 9.88 fold respectively). Furthermore, the enzyme activity ratio (glutathione-S-transferase) was relatively greater, and corresponded to the higher LC50 values of neonicotinoids for very high, high, medium and low pesticide usage areas. Our study suggested that the higher activity of the detoxifying enzyme in the resistance population of cotton leafhopper apparently has a significant role in endowing resistance to neonicotinoid groups of insecticides. However, this study recommends using neonicotinoids in cotton growing areas with caution.
