本稿は，ガーナ，インドネシア，ベトナムの3 カ国でプラスチック汚染対策のためのステークホ ルダー協働の制度化に，「中心的なアクター」と しての役割を果たしたと考えられるナショナル・ プラスチック・アクション・パートナーシップ （NPAP）について，著者らが実施した調査・分析 に基づいている（Asokan et al., 2023）．NPAPは， 世界経済フォーラムのイニシアティブであるグ ローバル・プラスチック・アクション・パート ナーシップ（GPAP）の一環として各国単位で形成 されたイニシアティブである．本研究の目的は， このNPAPの事例を通じて，プラスチック汚染対 策のステークホルダー協働の仕組みについて分析 し，現在合意に向けた交渉が行われているプラス...

Integrating the Sustainable Development Goals (SDGs) into climate actions is essential for a healthy planet and people. Yet, national climate policies and international climate support programs often fail to explicitly recognize the interconnections between climate concerns and other priorities covered under the SDGs. This failure can leave key...

Illumination variations in non-atmospherically corrected high-resolution satellite (HRS) images acquired at different dates/times/locations pose a major challenge for large-area environmental mapping and monitoring. This problem is exacerbated in cases where a classification model is trained only on one image (and often limited training data) but...

Lichen is an important food source for caribou in Canada. Lichen mapping using remote sensing (RS) images could be a challenging task, however, as lichens generally appear in unevenly distributed, small patches, and could resemble surficial features. Moreover, collecting lichen labeled data (reference data) is expensive, which restricts the...

Urbanization and concomitant challenges pose a great threat to sustainable development. Urban and rural development interacts through the flows of people, materials, energy, goods, capital, and information. Without building sound urban–rural linkages, achieving development in one area could compromise it in another area. Achieving sustainable...

Droughts and floods are some of the major climatic hazards in the semi-arid areas of Sub-Saharan Africa (SSA). Climate change affects the periodicity and severity of such hazards, and eventually the well-being of many rural communities in the region, including semi-arid Ghana. Enhancing the resilience of local communities to droughts and floods...

Operational monitoring of vegetation and its response to climate change involves the use of vegetation indices (VIs) in relation to relevant climatic data. This study analyses the temporal variations of vegetation indices in response to climatic data (temperature and precipitation) to better understand the phenological changes in the Wa -West and...

Urban-rural linkages are an integral part of fostering development in both urban and rural communities. However, the focus on development tends to have an urban bias toward Sub-Saharan Africa (SSA) with an increase in urbanization. Ghana is one of the fastest urbanizing countries in SSA. This paper sought to identify the challenges of urban-rural...

With the advent of high-spatial resolution (HSR) satellite imagery, urban land use/land cover (LULC) mapping has become one of the most popular applications in remote sensing. Due to the importance of context information (e.g., size/shape/texture) for classifying urban LULC features, Geographic Object-Based Image Analysis (GEOBIA) techniques are...

To classify Very-High-Resolution (VHR) imagery, Geographic Object Based Image Analysis (GEOBIA) is the most popular method used to produce high quality Land-Use/Land-Cover maps. A crucial step in GEOBIA is the appropriate parametrization of the segmentation algorithm prior to the classification. However, little effort has been made to automatically...
