概括

布基纳法索瓦加杜古 (Ouagadougou) 的手工花岩石采石场显示出明显的地形变化和非正式性. 这些操作通常由妇女进行,涉及危险的条件和空气污染,需要对员工福利和健康标准的政策考虑.

科学领域:

环境科学环境科学
城市规划城市规划
社会科学社会科学社会科学

背景情况:

布基纳法索瓦加杜古的快速城市化增加了对建筑聚合物的需求.
传统的泥建筑正在被更耐用的材料所取代,推动了采石活动.
机械化和手工采石场为首都提供沙子,石和碎石.

研究的目的:

评估瓦加杜古的手工花岩采石场的范围,过程,社会经济和环境影响.
分析开采系统及其对Pissy和Yagma采石场的影响.
提供有关采石场运营和工人条件的政策决策的数据.

主要方法:

混合方法方法结合卡车计数,用于3D体积估计的空中图像,采访和空气质量测量.
3D建模用于详细地形变化和估计Pissy采石场的花岩开采量.
进行空气质量监测,以评估采石场环境中的颗粒物含量.

主要成果:

瓦加杜古以南的沙子开采达到了165公里,估计年产量为180万立方米.
皮西采石场显示了显著的地形变化,提取了近45万立方米的花岩.
由女性主导的手工花岩采石是非正式的,缺乏监管合规,并在Pissy带来了高颗粒物质的危险工作条件.

结论:

瓦加杜古的手工采石场的特点是非正式性,危险的条件和空气污染等环境问题.
采石场工人的社会经济现实,主要是女性,突出了他们的脆弱性和缺乏法律保护.
政策制定必须整合卫生标准,工人福利,并探索可持续城市发展的替代总体来源.

关键词:

这是一座手工采石场.非正式部门是非正式部门.资源开采资源开采资源开采沙子沙子沙子沙子城市化的城市化.西非西非是西非的一个地区.

Threats to Biodiversity

Threats to Biodiversity

There have been five major extinction events throughout geological history, resulting in the elimination of biodiversity, followed by a rebound of species that adapted to the new conditions. In the current geological epoch, the Holocene, there is a sixth extinction event in progress. This mass extinction has been attributed to human activities and is thus provisionally called the Anthropocene. In 2019 the human population reached 7.7 billion people and is projected to comprise 10 billion by...
