Urban forests are becoming more critical as climate-induced disasters and disturbances tend to increase and affect cities. Forest managers are the responsible technical people on the ground to implement forestry-related climate policies. There is limited knowledge on the capacities of forest managers related to climate change issues. In this study, we surveyed 69 forest district managers of 28 provinces and compared their responses with actual data to understand their perceptions of urban green areas and climate change issues. We used a set of digital maps of the 1990-2015 period to identify land cover changes. To calculate the urban forest cover in the city centers, we used the city limit delineation shapefiles produced by the EU Copernicus program. We also employed the land consumption rate/population growth rate metric and a principle component analysis (PCA) to identify and discuss the provinces' land and forest cover changes. The results showed that forest district managers were aware of the general condition of the forests in their provinces. Still, there was a considerable inconsistency between actual land use changes (i.e., deforestation) and their responses. The study also revealed that the forest managers were aware of the increasing influence of climate change issues but were not knowledgeable enough to establish the connection between their tasks and climate change. We concluded that the national forestry policy should prioritize the urban-forest interaction and develop the capacities of district forest managers to improve the efficiency of climate policies on a regional scale.
随着气候引发的灾害和干扰趋于增加并影响城市,城市森林正变得愈发重要。森林管理者是在实地负责执行林业相关气候政策的技术人员。关于森林管理者应对气候变化问题的能力,目前了解有限。在本研究中,我们调查了28个省份的69位林区管理者,并将他们的回答与实际数据进行比较,以了解他们对城市绿地和气候变化问题的看法。我们使用了一组1990 - 2015年期间的数字地图来识别土地覆盖变化。为计算市中心的城市森林覆盖率,我们使用了欧盟哥白尼计划生成的城市边界划定形状文件。我们还采用土地消耗率/人口增长率指标以及主成分分析(PCA)来识别和讨论各省的土地和森林覆盖变化。结果表明,林区管理者了解其所在省份森林的总体状况。然而,实际土地利用变化(即森林砍伐)与他们的回答之间仍存在相当大的不一致。该研究还表明,森林管理者意识到气候变化问题的影响在增加,但在建立其任务与气候变化之间的联系方面知识不足。我们得出结论,国家林业政策应优先考虑城市 - 森林相互作用,并培养林区管理者的能力,以提高区域层面气候政策的效率。
