This booklet presents results obtained within the ALOS Kyoto & Carbon (K&C) Initiative. The Initiative builds on the experience gained from the JERS-1 Global Rain Forest and Boreal Forest Mapping (GRFM/GBFM) projects, in which SAR data from the JERS-1 satellite were used to generate image mosaics over the entire tropical and boreal zones of Earth. While the GRFM/GBFM projects were undertaken already in the mid 1990's, they demonstrated the utility of L-band SAR data for mapping and monitoring forest and wetland areas and the importance of providing spatially and temporally consistent satellite acquisitions for regional-scale monitoring and surveillance. The ALOS K&C Initiative is set out to suppor t data and information needs raised by international environmental Conventions, Carbon cycle science and Conservation of the environment. The project is led by JAXA EORC and supported by an international Science Team consisting of some 25 research groups from 14 countries. The objective of the ALOS K&C Initiative is to develop regional-scale applications and thematic products derived primarily from ALOS PALSAR data that can be used to meet the specific information requirements relating to Conventions, Carbon and Conservation. The Initiative is undertaken within the context of three themes which relate to three specific global biomes; Forests, Wetlands and Deserts. A fourth theme deals with the generation of continental-scale ALOS PALSAR image mosaics. Each theme has identified key products that are generated from the PALSAR data including land cover, forest cover and forest change maps, biomass and structure (Forests), wetlands inventory and change (Wetlands) and freshwater resources (Deserts). Each of these products are generated using a combination of PALSAR, in situ and ancillary datasets. The mosaic data sets and thematic products generated within the Initiative are available to the public at the K&C homepage at JAXA EORC: http://www.eorc.jaxa.jp/ALOS/en/kyoto/kyoto_index.html

Despite growing recognition that complex population portfolios are important sources of ecosystem stability and resilience, the structure of such stock complexes is often not considered in monitoring schemes to inform environmental impact assessments. The use of “index” or “indicator” sites, and of short assessment windows, to make broad claims about the relative importance of specific habitats or populations within a portfolio, assume that regional populations are highly synchronous and that abundance is stable through time. Asynchrony among populations and changes in population productivity over time render these assumptions fundamentally flawed. We used 57 years of abundance data for sockeye salmon (Oncorhynchus nerka) spawning in a set of eight streams in the Wood River watershed, southwest Alaska, to demonstrate how natural patterns of variability affect the ability of fixed assessment windows to characterize the contribution of individual populations to the entire portfolio. Additionally, simulations were used to demonstrate how different levels of synchrony and autocorrelation affect the ability of monitoring schemes to estimate the contributions of individual populations to a portfolio over the long-term. We found that fixed assessment windows were distinctly limited in their ability to characterize a population’s contribution to a portfolio over the long-tem. Asynchronous dynamics among populations, and the presence of autocorrelation that creates slow changes in populations, weaken the ability to characterize a stream's potential contribution to a portfolio from short-term assessments. These results suggest that the structure of population portfolios, and the presence of directional changes in productivity within individual populations, need to be taken into account when carrying out environmental risk assessments that aim to measure the contribution of an individual population or habitat to system wide dynamics. Typical risk assessments that depend on short monitoring periods are likely to vastly underestimate the potential long-term value of any specific habitat, and the population it supports, as a component of a multi-population portfolio.
