4. Proposed Plan:-Sustainable agriculture for Soil Health
and Food Security
 The basis of the food system is a healthy soil.
 Good soils yield good crops, which is consumed by people and other
animals. Indeed, the amount and quality of food are closely related to the
state of the soil.
 One of the most significant and prevalent issues of the modern period
limiting environmental sustainability and global food security is salt of the
soil.
 The main causes of slow pace agricultural growth are rising air
temperatures, intense rainfall events, weather patterns (such as protracted
droughts and floods), shifting soil fertility and health, new pest
infestations, and an increase in salt-affected areas.
 The climate-smart agriculture is regarded as a practical strategy for
securing food security in an adverse environment.

5. Ideal Sustainable Agriculture System
 A sustainable agricultural system, according to the American Society of Agronomy (1989) is one that, over an extended period of time:-
a. Satisfies the demand for food produced by humans,
b. Makes the best use of land and other resources,
c. Improves social and economic conditions for the local population,
d. Increases environmental quality through the adoption of agricultural practises,
e. Accepted politically and socially.

6. OBJECTIVES
 Econometric analysis of determinants of soil salinity
Bioremediation (aims to restore soil damaged by
salinity)
Plant growth promoting rhizobacteria

7. Research questions
 Investigating/ analyzing/ studying the potential of using biochar to improve crop yields as well as the impact
of plant development and crop yields on soil quality.
 Investigating how agroforestry and ecological services affect soil health in sustainable farming practices.
 Examining the possibilities of organic farming to enhance soil health and lessen environmental impact, and
aquaponics to boost food production.
 looking into how agricultural subsidies and climate-smart farming methods affect resilience and food
security.
