Answer 1

Social forestry refers to the management and protection of forests and afforestation on barren lands with an aim of helping within the environmental, social, and rural development.

Complete answer:
The essential objective of social forestry is to raising plantations by someone so on meet the growing demand for timber, fuelwood, fodder, etc, thereby reducing the pressure on the conventional forest area. This idea of village forests to satisfy the necessities of the agricultural people isn't new. It's existed through the centuries everywhere in the country but it absolutely was now given a replacement nomenclature.
The objective of Social Forestry
Improve the environment for shielding agriculture from adverse climatic factors,
Increase the natural good thing about the landscape; create recreational forests for the great thing about rural and concrete population,

Provide jobs for unskilled workers
Reclaim wastelands. Finally, its object is to spice up the standard of living and quality of life of the agricultural and concrete people.
Leucaena leucocephala (Subabul) a quick-growing insufficient herb included in social forestation. It’s found in open woodlands, gardens, parks, waste areas, disturbed sites, and on coastal foreshores and offshore islands. It should be a weed of open habitats, semi-natural, disturbed, degraded habitats, and other ruderal sites.
Components of Social Forestry to keep with National Commission on Agriculture:
Urban Forestry: It aimed to bring trees to the door of the urban people. It advocates the beautification of houses, roads, and vacant lands as also the creation of tree reserves, in towns and cities. Moreover, it stresses the aesthetic development of urban areas.
Rural Forestry: It envisages on the plantations of multi-utility of trees at a certain distance in arrow in step with the crops is completed under agroforestry.
Farm Forestry: In farm forestry, farmers are given incentives by the govt. And encouraged to plant trees on their own farms. A farmer needs firewood for cooking and agricultural implements, fodder for cattle, and manure for his fields.

With an appropriate choice of tree species and also the adoption of the scientific silvicultural practice, the farmer can considerably argument his income, without adversely affecting agriculture.

Therefore, the proper option is B, Leucaena glauca.

Note:
Benefits of Social Forestry:
Increased Biodiversity: Growing of trees in barren lands within the community helps to extend biodiversity value. As trees grow larger, the character of the habitat will change. Well-managed forests encourage biodiversity as they provide habitation for various animals, plants, shrubs, insects, and birds among others.
Carbon removal – trees act as carbon sinks!: In the fight against the worldwide warming effect, trees play a necessary role in the removal of carbon from the environment. Trees use Carbon dioxide when growing and thus, removing it from the environment.
Social forestry is seen as a promising method to reduce greenhouse emissions in urban settings. Trees’ energy-saving effect also indirectly lowers carbonic acid gas emissions by reducing the demand for power.
Soil conservation: Another critical advantage of social forestry is conservation. Communities that embrace social forestry enjoy significant benefits in terms of improved agricultural activities. Tree roots prevent eroding by holding soil in situ, mitigating the negative effects of eating away.
Health benefits: The effects of trees and nature on human health are well researched. Trees and nature are natural remedies for stress and anxiety. When people are stressed, they typically take a go into the parks and other nature trails for the calming effect.
