Diagnosing scaling bottlenecks in 10 community conservation initiatives in southern and eastern Africa

open access: yesConservation Biology, Volume 40, Issue 2, April 2026.
Scaling area‐based conservation, including initiatives led or comanaged by Indigenous Peoples and local communities, is a flagship goal of the Kunming‐Montreal Global Biodiversity Framework. Conservationists often aspire to scale initiatives, but this is rarely achieved in practice. Identifying and addressing factors that limit initiative adoption (i.e.

Strengthening community‐based fisheries monitoring programs with Indigenous perspectives

open access: yesConservation Biology, Volume 40, Issue 2, April 2026.
Abstract Community‐based monitoring (CBM) programs are increasingly recognized as essential for adaptive environmental stewardship. Yet, the CBM literature often highlights successful cases and privileges evaluations by external experts over those of community members themselves.

东北黑土带土地利用变化特征及生态敏感性评价

open access: yesShuitu Baochi Xuebao, 2023
东北黑土带是我国重要的商品粮生产基地,土壤质量退化、水土流失等问题直接影响生态与粮食供给安全,为明晰东北黑土带土地利用变化特征及评价生态敏感性,以2000年、2005年、2010年、2015年、2020年东北黑土带5期土地利用数据为基础,采用转移矩阵、地理探测器、综合生态风险评价等方法,研究景观格局及生态风险变化趋势。结果表明:(1)2000-2020年,研究区未利用地面积增加1 035.7km2,水域面积减少975.8 km2,土地利用变化最明显,耕地是阶段性变化较为剧烈的土地利用方式;(2 ...

基于GIS的土地利用类型与山地灾害敏感性分析--以云南省昆明市东川区为例

open access: yesShuitu Baochi Xuebao, 2004
人类不合理的土地利用方式对山地灾害具有明显的促进作用,但与此相关的定量研究成果则较少报道。以云南省昆明市东川区为例,在RS和GIS技术支持下,探讨了山地灾害敏感性系数(SC)的计算方法,定量分析了不同坡地土地利用方式对泥石流和滑坡、崩塌的综合敏感系数。发现区内对山地灾害最敏感的土地利用方式为工矿用地、道路建设用地、>35°的未利用裸地、>25°的低覆盖草地、8°~15°和25°~35°的灌丛地以及>25°的旱地;最不敏感的土地利用方式是水库常年蓄水位以下的土地、河滩地、密林地。根据综合敏感系数大小 ...

Impacts of Human Development on Wildlife Use of Corridors in Botswana 人类开发对博茨瓦纳野生动物廊道利用的影响

open access: yesIntegrative Conservation, Volume 5, Issue 1, Page 164-171, March 2026.
This study examined the effect of landscape‐scale human impact on wildlife in Botswana. We examined how species use wildlife corridors in two different human‐dominated landscapes. We identified differences in temporal overlap between wildlife and humans across both landscapes, which is fundamental to consider in both current and future conservation ...

延怀盆地葡萄种植区不同土地利用方式表土风蚀特征分析

open access: yesShuitu Baochi Xuebao, 2019
研究延怀盆地葡萄种植区不同土地利用方式下土壤风蚀特征,可为区域土地利用布局调整、生态环境建设提供数据支撑。以怀来县为研究对象,采用野外调查和室内分析相结合的方法,分析了葡萄、果桑、欧李、玉米留茬免耕、玉米翻耕5种土地利用方式的2018年11月-2019年3月土壤含水量、粒径及风蚀量月变化特征。结果表明:(1)未出现降水事件之前,5种土地利用方式土壤含水量均呈现随时间增加而下降的趋势,3种林果用地中土壤水分下降幅度表现为葡萄 > 欧李 > 果桑。(2)研究区5种土地利用方式表层土壤粒度主要为砂砾 ...

河套盐碱地不同利用方式土壤盐碱化特征差异分析

open access: yesShuitu Baochi Xuebao, 2020
为研究河套平原盐碱地在不同利用方式对土壤盐碱化特征分布的影响,通过野外调查取样和室内分析相结合的方法,对5种土地利用方式下(林地、农用地、牧草地、改良地、盐荒地)不同深度土壤剖面形态特征、可溶盐含量、盐分离子组成、总碱度、pH、碱化度等指标的变化规律进行了系统研究。结果表明:不同利用方式土壤剖面土体结构、颜色、根系分布、石灰性反应及碱化层分布均有明显差异;土壤剖面的可溶性盐、阴阳离子分布因土地利用方式不同而存在差异,牧草地和林地土壤剖面可溶性盐呈"橄榄"型、盐荒地和改良地呈"表聚"型、农用地呈"底聚"型;
