摘要
对实现工业化和经济多样化的追求为非洲领导人带来了一种新的思维形式,这对地理空间和农村生计产生了影响。政府正在租赁大片农村土地开采矿产资源。但是,很少注意发展基线条件,以促进大规模采矿和农业之间可能的和平共存,而农业是农村的基本生计活动。因此,本研究评估了加纳西北矿区的土地利用/覆盖条件,以确定村庄一级农业和大规模采矿勘探活动的可用空间。该研究结合了2000年和2014年的Landsat卫星图像,以及参与式地理信息系统(Participatory Geographic Information Systems),将景观分为四种主要的土地利用/覆盖类型,即:水、涝渍、植被和被占用土地。被占领的土地包括农田、定居点和裸地。研究发现,在2000年至2014年期间,该地区的大部分地区都具有内涝特征和洪水潜力,同时当地空间的大规模勘探和采矿活动也在增加。总体而言,被占用土地的净空间增益约占该地区总土地覆盖面积的47%。大部分的增长发生在研究区域的Nadowli-Kaleo和Jirapa地区,这些地区的勘探租约分布广泛。人们还注意到,在勘探和矿区周围的村庄里,荒地和定居点正在扩大。这一现象是附近村庄采矿和农业之间可能发生土地使用冲突的信号,必须在矿山投产之前加以解决。
Evaluation of Farmland availability and Large- Scale Mining Sector Activities at Village Scale
The quest to achieve industrialisation and economic diversification has brought a new form of thinking current among African leadership, which has implications for geo-space and rural livelihood. Governments are leasing large tracts of rural lands for mineral resource extraction. However, little attention has been given to developing baseline conditions that would facilitate a possible peaceful co-existence between large-scale mining and agriculture which is a basic rural livelihood activity. Hence, this study appraises land use/cover conditions of the Northwest mining region of Ghana to identify the availability of space for farming and large-scale mining exploration activities at the village level. The study uses a combination of Landsat satellite imagery for the years 2000 and 2014, and Participatory Geographic Information Systems to classify the landscape into four major land use/cover types, namely: water, waterlog, vegetation and occupied lands. Occupied lands include farmlands, settlements and bare grounds. It is found that between 2000 and 2014, much of the area is characterised by waterlog features and flood potentials juxtaposed to an increasing large-scale exploration and mining activities interest in local space. Overall, the net gain of space by occupied lands is about 47% of total land cover in the area. Much of this gain is in the Nadowli-Kaleo and Jirapa areas of the study region where exploration leases are wide-spreading. It is also observed that there is an expansion of barelands and settlements in the villages around the exploration and mine sites. This phenomenon is a signal of potential land use conflict between mining and farming in villages nearby and must be addressed before mine commissioning.
