Precision Farming merges the new technologies borne of the information age with a mature agricultural industry. It is an integrated crop management system that attempts to match the kind & amount of inputs with the actual crop needs for small areas within a farm fields. This study is basically based on the secondary data and it is a review paper. As it is a review paper so, there was less opportunity to follow any specific method in preparing this paper. Valuable information has been collected through internet browsing, journals etc. In this paper, we examine that, GPS, GIS, VRT, profitability, yield mapping etc. are most common precision agriculture techniques where, GIS can help in site-specific applications of fertilizers and soil amendments and help effectively detect and map black fly infestations, making it possible to achieve precision in pest control. Remote sensing combined with GIS and GPS can help in site-specific weed management. From the review we observed that, the global adoption of yield monitors has been predominated in North-America and Europe. The precision technologies have been used on a wider variety of crops in Denmark and UK than in the US. In Bangladesh, precision agriculture has great prospect as our country is highly natural calamity sensitive and through it we can easily take measure to prevent our agricultural products from damage caused by natural calamities. Though, precision agriculture is very costly but the benefit from it is more than its cost for most of the developing countries. So, the precision agriculture has great prospect in Bangladesh as well as in the world and it is the utmost time to adopt this technology in our traditional agriculture.Res. Agric., Livest.

Bangladesh is an agrarian-based developing economy that has recently achieved accelerated economic growth via its industrial sector. Such levels of industrial development have increased energy demands, with negative impacts not only on human health but also on agricultural land and biodiversity. these forms of environmental degradation pose risks to rice production, the main agricultural crop, due to associated declines in soil, water, and air quality. this study intends to analyze rice farmers' level of awareness and perception of the impacts of environmental degradation, and factors influencing the awareness. Primary data were collected from 300 rice producers in six districts in Bangladesh during August-September 2019 by a structured questionnaire, where agricultural arable lands have been degraded the most. A multinomial logit model has been used to explore the relationship among key factors. Farmer awareness levels varied according to age, farming experience, farm household income, adoption of inclusive agribusiness, access to extension workers, and distance from the nearest industrial zone. there was spatial heterogeneity among rice grower perceptions of the impacts of environmental degradation. Government guidance and some socio-economic factors could reshape and improve the farmer awareness levels on natural degradation, to facilitate the maintenance of farm operations and food security nationwide.
