In the last decade, the Government of Indonesia has focused on the production development of 4F crops, meaning crops for the production of Food, Feed, Fiber, and Fuel. In 2014, Indonesia had about 101 million hectares agricultural land which comprised of approximately 47 million hectares cultivated area and the remaining 54 million hectares were expandable agriculture lands. However, the expansion has to consider Indonesia Law No. 44 in Year 2009 (Undang – Undang No 4 Tahun 2009) regarding the security of sustainable food cropland that restricts the conversion of food cropland into timber forest, industry or settlements. In fact, unwanted land use land cover (LULC) change happened due to the excessive expansion of oil palm, rubber, pulpwood and mining industries particularly in East Kalimantan. Two districts that exhibit significant LULC change are Kutai Barat and Mahakam Ulu. An additional 78.5 thousand ha of rubber, 31 thousand ha of oil palm and 23.6 thousand ha of pulpwood plantations have dominated the LULC change in Kutai Barat and Mahakam Ulu districts from 1990 to 2009. Although in general, the agricultural expansion has become the main cause of unwanted LULC change and forest cover loss, these have also contributed to positive economic benefit. In order to evaluate the economic benefit of historic agricultural expansion as well as to estimate the economic benefit of future agricultural expansion, it is necessary to look thoroughly at the geographic distribution of crop yields within the districts because we would like to understand the crop yield for every agriculture production area. The issue on the existing crop statistic data is that the crop statistics are conveyed as tabular-based data and reported at the national, provincial or district level of detail. Thus, examining crop distribution in district level is certainly challenging. Hence, a spatial crop yield allocation model was applied to generate pixel-level crop yield representation of Kutai Barat and Mahakam Ulu districts in 2000 and 2009 based upon available the regional crop statistics data and the existing LULC maps and further analyze its spatial-temporal pattern within this period of time. Furthermore, an evaluation of crop yield production and the agriculture 2 expansion trend from 2000 to 2009 were applied to a 2030 land use projection from a land use change model to project the pixel level crop yield in 2030. Between 2000 and 2009, rubber plantation exhibits land expansion and followed by the increase of yield. While the expansion of oil palm in 2009 is followed by the degradation of yield. We presume this due to the oil palm plantation in 2009 is still in early harvesting stage. The accuracy of disaggregation model is highly depending on the quality of data particularly crop statistic data and LULC map. The deviation between these two data leads to the occurrence of a high error in disaggregation results. By estimating oil palm and rubber yield based on projected LULC maps in 2030, the future expansion is suggested to follow the Limited Unrestricted scenario since this scenario is able to provide highest average yield with relatively small area among other scenarios. In this manner, either government or people in Kutai Barat and Mahakam Ulu are able to gain optimal agricultural benefit without sacrificing an excessive number of land resources.Verstegen, JudithPla Bañón, FilibertoLaan, Carina van derRUNPramujati, Muhammad Wakhid2018-04-03T15:32:56Z2018-02-022018-02-02T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisapplication/pdfhttp://hdl.handle.net/10362/33712TID:201892987enginfo:eu-repo/semantics/openAccessreponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAP2024-03-11T04:18:29Zoai:run.unl.pt:10362/33712Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-20T03:30:03.622779Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse
