Gracet in 1990 defined Sustainable Agriculture as – A system of agriculture that is committed to maintain and preserve the agriculture base of soil, water , and atmosphere ensuring future generations the capacity to feed themselves with an adequate supply of safe and wholesome food A Sustainable Agriculture system is one that can indefinitely meet demands for food and fibre at socially acceptable, economic and environment cost Thus, Sustainable Agriculture is the one which Minimizes adverse impacts on health, safety, wildlife, water quality and the environment by 1. Minimizing the use of non renewable resources 2. Renewing soil fertility and natural resource base 3. Achieving a natural integration of biological cycles benefitting agriculture and enviornment

I think sustainabkr agriculture is the future of world.
The ultimate goal of sustainable agriculture is to develop farming systems that are productive and profitable, conserve the natural resource base, protect the environment, and enhance health and safety, and to do so over the long-term.
This ultimate goal of sustainable agriculture can be achieved through
1. low input methods –
Low-input farming systems seeks to minimize the use of external production inputs (i.e., off-farm resources), such as purchased fertilizers and pesticides –
to lower production costs
to avoid pollution of surface and groundwater
to reduce pesticide residues in food
to reduce a farmer’s overall risk
and to increase both short-term and long-term farm profitability
Also,  most high input systems are not either economically or environmentally sustainable over the long-term
2. Skilled management
Skilled management is reqired to optimize the management and use of internal production inputs (i.e., on-farm resources) to achieve economically profitable returns
Skilled management ensures the following
1. Reduced or no use of synthetic chemcial inputs
2. Biological pest control
3. Soil and water conservation measures
4. Use of animal and green manures
5. Crop rotations
6. Use of organic wastes
7. Crop livestock diversification
8. Mechanical cultivation
9. Use of Naturally occuring processes
Goals of Sustainable Agriculture
Incorporation of natural processes such as nutrient cycling nitrogen fixation and pest-predator relationships into agricultural production processes
A reduction in the use of off-farm, external and non renewable inputs
The full participation of farmers and rural people in all processes of problem analysis and technology development, adoption and extension
A more equitable access to predictive resources and opportunities, and progress towards more socially just forms of Agriculture
A greater productive use of the biological and genetic potential of plant and animal species
A greater productive use of local knowledge and practices, including innovation in approaches not yet fully understood by scientists or widely adopted by farmers
An increase in self-reliance among farmers and rural people
An improvement in the match between cropping patterns and the productive potential and environmental constraints of climate and landscape to ensure long-term sustainability of current production levels
Profitable and efficient production with an emphasis on integrated form management and the conservation of soil, water, energy and biological resources
