摘要
可可种植是对厄瓜多尔国内生产总值贡献最大的行业之一。本研究旨在确定厄瓜多尔沿海 71 个城市的可可土地使用冲突(UC)。该研究采用照片解释来确定作物的位置,并使用地理空间建模来分析土地使用能力(LUC)标准、农业生态要求和 1:5,000 的土地使用能力。在研究的总面积中,可可作物占 4.65%,其中 66.03% 的可可作物得到了充分使用,33.97% 的可可作物处于土地利用不足状态,而处于土地利用不足状态的可可作物最多,占总面积的 17.25%。在沿海地区,瓜亚斯省的 LUC 最低,与洛斯里奥斯省形成鲜明对比;作物的主要 LUC 为 III 级,占 34.32%。研究结果表明,可可的土地利用变化(LUC)与国家农业生态分区(AZ)的一致性较低,因为该模型考虑的是自然条件下的作物,主要限制因素是植被湿润期,并没有考虑作物是否存在于该地区。使用国家 AZ 信息来确定作物可能会限制其产量,因为事实证明,有些种植区并不冲突,而且被农民开发利用。这项研究可推广到其他作物,也可扩展到任何地区。
Theobroma cacao L., land use conflict on the Ecuadorian coast
Cocoa cultivation is one of the sectors that most contributes to Ecuador’s GDP. The aim of this study is to determine the Land-Use Conflict (UC) for cocoa in 71 cities on the coast of Ecuador. Photointerpretation has been applied to locate the crop and geospatial modeling has been used to analyze Land Use Capacity (LUC) criteria, agroecological requirements and LUC at 1:5,000. Of the total study surface area, 4.65% is occupied by cocoa crops and of this value 66.03% is in adequate use (AU) and 33.97% in LUC, and the category of UC over lightly used is the most frequent with 17.25% of the total surface in LUC. In the coastal region, the province of Guayas has the lowest LUC in contrast to Los Rios; the predominant LUC for the crop is Class III 34.32%. The findings show that the LUC of cocoa has a low concordance with the national Agroecological Zoning (AZ), since this model considers the crop in natural conditions, the main limiting factor is the vegetative wet period and does not take into account whether the crop is present in the territory. The use of national AZ information to establish crops could limit their production, since it has been demonstrated that there are cultivated areas that are not in conflict and that are exploited by farmers. This study is replicable to other crops and scalable to any area.
