Mechanization and the Global Development of Conservation Agriculture
نویسنده
چکیده
The per capita availability of agricultural land was 0.43 ha in 1960 and declined to 0.26 ha in 1999. Significant per capita declines are projected in the availability of another essential natural resource for agriculture water. At the same time, the world must increase its food production by some 70% by 2050 to meet the needs of its growing population projected to reach 9.2 billion then [Bruinsma, 2003].
