It is estimated that the poor in rural areas represent a quarter of the 1,200,000 poor people in the world. In some countries, the figures rise up to 90%. The major cause of this growth in poverty occurs when small land owners undergo increasing pressure to abandon the agricultural sector. This process is also fueled by marketing and political forces that affect land ownership, rent, prices, access to loans, goods and services, and investment in social and physical infrastructure. Agricultural development is a key factor in reducing rural poverty as research shows that at least 53 cents per dollar paid in production is kept in rural areas. [ABSTRACT FROM AUTHOR]
