Land use/land cover (LULC) maps are now being used across disciplines for many different types of applications, e.g., to analyze urban heat islands or rainfall-runoff dynamics. Traditional map accuracy metrics are limited in this regard, as they only assess LULC map thematic accuracy. In reality, some types of misclassification lead to larger...

Image segmentation and geographic object-based image analysis (GEOBIA) were proposed around the turn of the century as a means to analyze high-spatial-resolution remote sensing images. Since then, object-based approaches have been used to analyze a wide range of images for numerous applications. In this Editorial, we present some highlights of...

Key point Analyzed several water quality parameters (pH, electrical conductivity (EC), total dissolved solids (TDS), Chloride (Cl), and temperature) based on 35 well samples collected by local government staff in Oriental Mindoro Province of the Philippines. Cl- concentration was calculated using salinity values based on Equation: Sal (ppt) = 0...

Effective management of invasive alien species (IAS) requires comprehensive stakeholder engagement and a clear understanding of how people interact with these species. Such interactions are particularly complex in socio-ecological production landscapes and seascapes (SEPLS), where local communities and their environment are highly inter-dependent...

Due to the cumulative effects of rapid urbanization, population growth and climate change, many inland and coastal water bodies around the world are experiencing severe water pollution. To help make land-use and climate change adaptation policies more effective at a local scale, this study used a combination of participatory approaches and computer...

Spatial urban growth and its impact on land surface temperature (LST) is a high priority environmental issue for urban policy. Although the impact of horizontal spatial growth of cities on LST is well studied, the impact of the vertical spatial distribution of buildings on LST is under-investigated. This is particularly true for cities in sub...

平成30 年12 月に施行された「気候変動適応法」において、国際協力を推進する旨が定められている。また、平成27 年12 月に国連気候変動枠組条約（UNFCCC ）の下で合意されたパリ協定においても、気候変動への適応分野において国際協力の重要性が掲げられている。我が国は科学的知見に基づいた適応計画の策定支援を「アジア太平洋地域における気候変動適応分野の研究、人材育成支援業務」として、平成27 年度から平成29 年度まで継続して実施（以下「適応支援第１フェーズ」という。）しており、途上国政府及び研究機関等との協働が可能となるよう、アジア太平洋地域の適応に関する能力向上のための人材育成、知見共有等を図ってきた。 平成31年度の事業においては、適応支援第１フェーズ及び「平成30...

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...

This chapter contributes to improve an understanding of the effectiveness of different biodiversity science-policy interfaces (SPIs), which play a vital role in navigating policies and actions with sound evidence base. The single comprehensive study that was found to exist, assessed SPIs in terms of their ‘features’—goals, structure, process...

Owing to the huge number of species observations that can be collected by non-professional scientists, “citizen science” has great potential to contribute to scientific knowledge on invasive alien species (IAS). Citizen science has existed for centuries, but the recent adoption of information and communications technology (ICT) in this field (e.g...
