In 1965, India averaged 854 kilograms of grain per hectare in use, while Sub Saharan Africa averaged almost the same, 773 kilograms per hectare.

The value of loss is calculated using a service hectare year metric, representing the level of ecological service provided by one hectare in a year.

But, by 2000, India was producing 2,293 kilograms per hectare, while Africa was producing only 1,118.

As a result of the Presidential Decree of 1 December 1997, No. 874, on the allocation of 25,000 hectares of land for private plots for citizens, individuals have acquired the right to obtain land for a private plot of up to 0.15 hectare of irrigated land and up to 0.50 hectare of dry land.

The solution is to increase grain yields to at least two tons and in some places to three or more tons per hectare.

According to Saudi Arabia, Shadco's average barley production per hectare during 1989 to 1990 was approximately 5.5 tonnes.

This rate decreased to approximately 3.4 tonnes per hectare during 1990 to 1991, a reduction in yield of approximately 2.1 tonnes per hectare.

Under traditional agricultural conditions, the yields of grain rice, wheat, maize, sorghum, or millet are usually around one ton per hectare, for one planting season per year.

The merits of bio prospecting have been examined carefully, and the returns are in fact very modest, ranging from just 0.20 per hectare in parts of California to 20 in Western Ecuador.
