In developing countries, pressure to increase agricultural productivity has resulted in?

The correct choice indicates that in developing countries, the pressure to increase agricultural productivity has often led to the conversion of forests into agricultural fields. This practice is driven by the need to expand the land available for cultivation in order to meet the demands of a growing population and enhance food security. When forests are cleared to create additional farmland, it can result in immediate increases in agricultural production, but also comes with significant environmental consequences such as loss of biodiversity, disruption of ecosystems, and increased greenhouse gas emissions from deforestation.

The scenario described reflects a broader trend where the pursuit of higher agricultural outputs often compromises environmental sustainability. In many developing regions, the priority placed on short-term agricultural gains can overshadow the long-term implications of land use changes, particularly in sensitive forested areas. Other options presented, such as increased yields or more sustainable use of land, may occur under certain practices but are not universally consistent with the overarching trend observed in many developing nations facing agricultural pressures.
