What Is Sustainable Anyway?

The pathway to "sustainability" is not always clear
Sustainability is a phrase that gets thrown around so frequently that there is little consideration about what the word really means. After all, who can be opposed to sustainable agriculture?

Sustainability was famously described as meeting the needs of the present without compromising the ability of future generations to meet their own needs.

The vision of sustainable agriculture is more philosophical than a well-defined goal. It certainly includes the stewardship of natural resources, financial security for farmers, and consideration of societal goals. However since there is no agreement on how to achieve these objectives, these terms can be twisted to meet personal agendas.
Using all nutrients efficiently should be a top goal

Many will agree that each person has an individual preference on how to balance current consumption with future enjoyment. Frequently we want things now, instead of waiting for a future reward. Some people are careful savers for the future, while others spend all that they earn. Achieving sustainability is a flexible goal that reflects individual priorities and incentives. There are also regional considerations that must be factored into sustainability objectives.
Providing an adequate food supply

The unprecedented pressure on the global food supply to meet the growing population requires close examination of all our current practices. Our soil and water resources are under severe stress in some areas. Like all geologic resources, the supply of phosphate and potash is fi nite in the world. Although there is no risk of fertilizer shortage in the next centuries, consideration of appropriate conservation and recycling practices should always be in the forefront of their use. Modern food systems require the input of considerable energy. There are numerous changes that can be made to make our food supply more sustainable.
Phosphate mining provides needed nutrients

Some groups promote a return to organic fertilization practices, other voices suggest that agroecology or integrated nutrient management is the path towards sustainability. Being dogmatic about a single solution causes more conflict than progress. There is no single path towards achieving agricultural sustainability.

Human nutrition is part of sustainability
IPNI is dedicated to the development and delivery of the best scientific information about the responsible use of plant nutrients. Instead of arguing over which definition of agricultural sustainability is correct, let’s get on with the task of using plant nutrients as efficiently and effectively as possible.
Growing adequate fiber and fuel also needs attention
