Changes in land use and land productivity over the period area analysed.

Low soil fertility is one of the greatest biological obstacles to increasing food production and improving land productivity.

India, one of the world's most populous countries, has taken steps in the past decades to increase its land productivity.

Forest serve as good indicators of land productivity.

The scope can be extended through increased land productivity.

Later, however, it became a major obstacle to the further intensification of agriculture, especially in comparison to the surrounding lowlands where land productivity increased rapidly.

Crop production indicates very low land productivity with the majority of farmers involved in coconut tree cultivation for copra as their main economic mainstay.

Because the cost is so modest, the increased land productivity helps the system pay for itself in a short time, Ms. Novogratz said.

Most of the local farmers practice intercropping to increase land productivity and lessen soil erosion.

With the decline in wheat prices and land productivity many countrymen were left looking for any hope of prosperity.
