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...

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...

Although it is widely acknowledged that forests provide critical ecosystem services for human survival and well-being, in the Asia-Pacific region forests are being converted to other land uses and degraded at alarming rates. One underlying factor for this destruction of forests is market failure. Forests are cleared for other land uses or degraded...

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...

Using “the sharing paradigm” as a guiding concept, this book demonstrates that “sharing” has much greater potential to make rural society resilient, sustainable and inclusive through enriching all four sharing dimensions: informal, mediated, communal and commercial sharing. The chapters are divided into two parts, one that focuses on case studies...

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...

TPP協定「環境章」において、各国による違法伐採の抑止に働く行政措置の強化が規定されるとともに、日EU・EPAの「貿易と持続可能な開発章」においても、各国が違法伐採及び関連する貿易への対処に貢献することが規定されている。これらに対応するために、我が国の違法伐採木材への対策として平成29年５月に施行された「合法伐採木材等の流通及び利用の促進に関する法律」（通称「クリーンウッド法」。以下「クリーンウッド法」という。）を着実に運用していく必要がある。 本事業は、林野庁ホームページ「クリーンウッド・ナビ」に掲載されている生産国リスク情報を、木材関連事業者等の利用者がより活用しやすくするための検討及び情報の整理を行うことを目的とした。具体的には、①リスク情報に基づく基本的な合法性確認（デュー...
