Agricultural land around Bangkok Metropolitan Area (BMA) is very diversified, but the land area declines continuously due to urban growth. There has been an attempt at city planning and compensation support to protect the remaining agricultural land, but the effort has not been accomplished. This thesis aims to study the condition of change and endurance of various kinds of agriculture in the Bangkok peripheries, basing on the paradigms on agricultural and city location, the persistence of communities, and the replacement by various kinds of agriculture. The methodology consists firstly of a review of characteristics agricultural land from the past to the present time. The review was shown in terms of maps, aerial photographs, and Geographical Information System (GIS). Secondly, agro-economics data pertaining to each crop from relevant agencies were collected to observe the trend of land use changes. Lastly, a survey was conducted on the existent of each kind of urban agriculture in the studied areas. All the information were then analyzed and synthesized with the paradigms, so as to rank the existence and trends of agriculture, including factors affecting the existence. The findings are used as recommendations for agricultural land conservation and management in the future. The findings indicate that urban agriculture that could best exit in terms of the economic benefits, types of agriculture and types of the environment are, in ascending order; orchid farming, grass farming, Leech Lime (Citrus hystrix DC.) growing, vegetable farming, aquaculture, growing of cut flowers, rice farming, mandarin orange orchards, aquatic plants and livestock raising. Traditional orchards do not exist anymore. The replacement pattern is characterized by the movement from the urban center, with rice farming and livestock raising being the furthest, due to lower returns. But orchid farming can expand in any area. Urban peripheries have the advantages of having less pests and are thus suitable for vegetable growing, especially non-toxic vegetables. The land previously used for agriculture in the west was now encroached and faces the problem of being cut through by the construction of main roads, leading to the establishment of urban housing complexes. If the urban agriculture is to continue existing, there must be certain adaptation and control of bypass roads, the limitation of residential complexes and sewage control, conservation of canals and allocation of water for agriculture, and the promotion of agricultural land for recreational purposes. In addition, there should be the intervention of deals on agricultural land adjacent to the city both in the Bang Ramad area and Sapan Sung area for the purpose of conservation, the compensation to owner of agriculture land according to the principle of sufficient economy, and lastly, there should be an increase in the types of agriculture in the eastern of the urban periphery.
