Background Agriculture sector occupies the centre stage in shaping India's socioeconomic status. The economy of the second most populous country in the world is inextricably linked to the pulse of its agricultural success or failure. India has witnessed a significant increase in food grain production after green revolution, oilseeds production after yellow revolution, milk production after white revolution, fish production after blue revolution, and fruits and vegetables production after golden revolution, since independence. The agricultural development has been achieved due to the application of science and technology coupled with the positive policy implementation, and hard work of Indian farmers (Ahuja 2000). However, after nearly three and half decades in the post-green revolution period, the country still faces crisis each year in trying to meet the burgeoning demand for food by its growing population. Thus, the need of research and development in the field of agriculture for increasing the application of frontier technologies (i.e. information technology application in agriculture, precision farming, post-harvest technologies, mechanized farming and organic farming) cannot be denied, which is a feasible

The modern urban planning is focused towards encouraging pedestrian movement by ensuring their safety and comfort during the walk. Further, COVID-19 pandemic has abruptly obstructed our normal way of life that includes of our local as well as global transport systems. There is greater need of making the public places more pedestrian friendly with the provision of appropriate walking and cycling networks, which can tackle the social distancing issues. This paper presents a novel approach to quantitatively analyze the efficiency of present urban pedestrian streets in maintaining social distances among pedestrians. The survey research techniques, GIS tool and technique; statistical techniques; and space syntax methods are implemented and tested for evaluating present scenario of the pedestrian movement in relation to the urban layout, in the case of Main-Market Street of Hamirpur town of Himachal Pradesh, India. The regression and correlation analysis is performed between outcomes of axial and segment analysis to establish the interrelation among spatial structure and behavioral phenomena. This paper is an attempt to generate the need of rethinking the pedestrian planning process with more holistic approaches to achieve sustainable urban environment.

The use of efficient building design strategies at the inception of the building project helps to improve the overall building energy performance. This paper focuses on the effect of aspect ratio of the floor plan on the energy performance of a building to reduce the energy demand of the office buildings. The other factors deciding energy performance of a building, like orientation, floor area, floor height, floor number and window to wall ratio, have been kept constant. The simulation is performed in Design Builder software, and the energy consumptions at different assumed cases have been analysed using correlation and regression analysis technique, thoroughly to find the optimum solution. The findings of this research will be useful in providing solutions for the reduction of energy demand of the office buildings in the study area.

The fundamental purpose of a building is to provide a comfortable and safe living environment, which protects from the extremes of surrounding environment, as well as give an opportunity of physical and psychosomatic development. The traditional buildings evolved gradually to meet the eventually changing human needs and lifestyle over a period of time, integrates the environmental and socioeconomic characters of the society in a well manner. These buildings have attained deep reconciliation with site surroundings, and thus, have minimal environmental impact. In spite of rapidly growing concept of advanced technological approach towards sustainability, the concept of indigenous technology and traditional architecture plays an active role. The main objective of this paper is to understand the principles and strategies for sustainability from traditional rural architecture and indigenous technologies. The methodology adopted is documentation of a traditional rural house of Nalanda, India, and analyse the environmental and socioeconomic aspects. The data has been collected from surveys, site measurements, literature, and other secondary sources. The thermal performance of a traditional house is analysed through computer aided simulations in the present investigation. This paper concludes with an appreciation of principles of traditional rural architecture and advocates their integration in the present scenario.

The provision of quality housing in adequate quantity is a major concern for planners in the developing regions. There is need of rapid housing development to meet the need of growing population while giving attention towards its minimal environmental impact. This paper focuses on the sustainable housing development using system dynamics model in the study area of Patna district, India. The optimum housing development has been suggested on the basis of result of analysis of various scenarios generated by performing simulation using control parameters in the formulated model. The environmental impact, like air pollution; noise; waste generation; water consumption; and energy consumption, due to the suggested housing development scenario has been discussed thoroughly, based upon which recommendations have been given. The findings of this research will be useful in providing solutions for the sustainable housing development to meet the growing demand as well as reduction of its adverse environmental impact in the study area.
