Urban agriculture has two components: vertical  and horizontal . The horizontal component of urban and peri-urban agriculture  has gained attention because of multiple functions that could improve food systems and ecosystem services under climate change . UPA cannot fully feed urban dwellers within its boundaries but can make an important contribution to local food security and nutrition  . UPA is also expected to play important roles in eco- system functions in addition to alleviating food shocks caused by natural disasters and reducing food mileage.
