However, increasing the area of cultivated marginal land also increases the total annual biofuel production. Total production could be increased if the definition of ‘‘marginal’’ were expanded to include more urban commercial land, as described in Section 3.1, which in fact captures more of GTECH’s identified and cultivated marginal lands. In addition, more marginal lands could be identified if the minimum size were reduced (here defined as 0.009 ha or 1000 ft2). Utilizing a greater number of smaller plots in addition to the current marginal plots could increase the total potential biodiesel production. However, caring for a greater number of plots would also require more person-hours and more organizational support to ensure proper agricultural care to facilitate the biodiesel production
