Sustainable agriculture is still an important issue.

A sustainable agriculture may be defined as one that offers increased sustainability without diminishing food production or modifying agro-forestry systems or natural resources.

Agriculture uses around 70 per cent of the Earth’s surface and has reduced its environmental footprint dramatically over the last two centuries. The most important natural resources that are required to Sustainable agriculture are water, water resources, natural environments and other natural systems.

The development of a sustainable agricultural sector will require energy, water, nutrients, soils and the ecological services of crops, land, forests and livestocks.

The resources required to produce all the natural resources that are needed to Sustainable agriculture, a given level of population, are highly limited. The major limitation is the productivity of arable land. Most of this land is under the limits of ecological services and is already arid, although it is under the limits of intensive agricultural production.

The renewable resource system consists of mostly renewable nutrients, such as fertile soil, water, energy and organic matter. Many of these resources are renewable, although the latter is limited. For example, agriculture uses around 70 per cent of the Earth’s surface and has reduced its environmental footprint dramatically over the last two centuries.

It is recognized that the agriculture system may be unsustainable and that it requires a high level of efficiency to ensure sustainability. Sustainable agriculture is defined as one that offers increased sustainability without diminishing food production or modifying agro-forestry systems or natural resources. The sustainability of an agricultural system depends on resource usage and energy consumption.

Appropriate resource use requires renewable resources and optimizes the use of natural resources by avoiding overuse of resources and by improving efficiency of use and management of resources.

A sustainable agriculture is particularly important in providing food to a growing population, and it requires integrated and sustainable resource use. Sustainable agriculture requires maintaining a stable agricultural system. This requires more arable land and the development of high-yielding and environmentally friendly crops.
