Abstract: The conducted studies on the Environmental and Agroforestry Systems of the Entisol Order soils of Bangladesh were with the objective of identifying the agroforestry systems in favor of environment covering entisols of northern Bangladesh. The areas of studies covered three major Districts and ten Upazilas. The technical type investigations were conducted involving agroforestry tree species and ecological components. It has been found that the national level respondents give more importance to several modern fruit trees but the local respondents show significantly less interest for those fruit species. The fruit species domination among them in descending order are lemon, mango, coconut, date palm, papaya and jujube as preferred by the farmer consumers. The Community Forest Tree Species domination show in descending order neem, bamboo, sisso and betelnut. The less dominant tree is jarul. The major trees domination in the char suitable for land and soil conservation arein descending order bamboo, neem, acacia, eucalyptus and palmyra palm. The less dominant tree is alder. The major crops domination in the char good for soil conservation arein descending order rice, wheat, arhar, kaon, blackgram, grasspea, maize and sungrass. The less dominant crops are data and okra. The major trees in the char dominated in homestead are indescending order bamboo, neem, banana, mango and mahogoni. The less dominant trees are alder, gliricidia and pitraj. The major trees in the char dominated in embankments are in descending order acacia, neem, sisso, eucalyptus and mahogoni. The less dominant trees are pitraj, betelnut, pummelo and chatim. The results found domination percentage in Agroforestry systems show that the Agro-Sylviculture (74%) and Agro-Sylvi-pastoral systems (81%) are more preferred by the consumer farmers and recommended as well in consideration of production sustainability.

I. INTRODUCTION

The circumstances, objects, or conditions by which one is surrounded and the complex of physical, chemical, and biotic factors that act upon an organism or an ecological community and ultimately determine its form and survival is known as environment i.e. the surroundings or conditions in which a person, animal, or plant lives or operates. To divide environments’ sorts, we can mention 3 kinds of environment-natural, industrial and social environment. Natural environment includes water, light, land, air and all organisms that live in nature.
