TOPIC -1

GENTRIFICATION

Gentrification is defined as the process by which wealthier (mostly middle-income) people move into, renovate, and restore housing and sometimes businesses in inner cities or other deteriorated areas formerly home to poorer people.

As such, gentrification affects an area's demographics because this increase in middle income individuals and families often results in an overall decline in racial minorities. Additionally, household size decreases because low income families are replaced by young single people and couples desiring to be closer to their jobs and activities in the urban core.

 

 

TOPIC -2

SLASH AND BURN AGRICULTURE

Slash and burn agriculture is the process of cutting down the vegetation in a particular plot of land, setting fire to the remaining foliage, and using the ashes to provide nutrients to the soil for use of planting food crops.

The cleared area following slash and burn, also known as swidden, is used for a relatively short period of time, and then left alone for a longer period of time so that vegetation can grow again. For this reason, this type of agriculture is also known as shifting cultivation.

 

TOPIC -3

LEED CERTIFICATION

LEED (Leadership in Energy and Environmental Design) certification is a third-party certification system developed by the United States Green Building Council that has become a nationally recognized standard in sustainable building and development. LEED uses five main areas to determine whether a building meets its standards for environmental and human health:

(a) Sustainable site development

(b) Water savings

(c) Energy efficiency

(d) Materials selection

(e) Indoor environmental quality
