Ecosystem services in global sustainability policies

Global sustainability policies, such as the Sustainable Development Goals (SDGs) or the Aichi Targets, aim to ensure sustainable development, including improved human well-being and the conservation of nature. Although not yet explicitly used to evaluate the progress towards sustainable development, the ecosystem service concept implies a direct link between biodiversity and human well-being. This study explores how and which ecosystem services are currently considered in the SDGs and the Aichi Targets. We also identify which information might be already available for monitoring the progress towards their goals by reviewing national ecosystem assessments. This allows the identification of the main knowledge gaps for monitoring progress towards these global sustainability targets.There is a wealth of information on all major ecosystem services categories which is directly relevant for the Aichi Targets and the SDGs. The top 25% most cited ecosystem services across both policy documents are: Natural heritage and diversity, Capture fisheries, Aquaculture, Water purification, Crops, Cultural heritage & diversity and Livestock. Most monitoring information recommended for the global sustainability goals, as well as in the information available from national assessments, is biased towards supply related aspects of ecosystem services flows. In contrast, there is much less information on social behaviour, use, demand and governance measures. Indicators are rarely available for all aspects of a specific ecosystem service.The national statistical bureaus currently in charge of providing observations for reporting on SDGs, could be well placed to address this bias, by integrating ecological observations with socio-economic statistics into socio-ecological indicators for ecosystem services flows. IPBES can potentially address the gaps identified in this paper by improving coverage of the different dimensions of ecosystem services flows.

An assessment methodology for successional systems. II. Statistical tests and specific examples

This paper presents a dynamic framework for environmental assessment when the system under study is undergoing successional change. Successional differences between sites for which one wishes to detect a difference because of a treatment are essentially confounding factors. We show how successional changes over the study period or resulting from differences in study site plot ages can be factored out by developing a null model of expected behavior over time. The null model for change in state with time is characterized in terms of a stochastic envelope around a nominal trajectory. Specific tests for the detection of trends associated with succession are described and illustrated on example data. It is concluded that the methods developed work particularly well for laboratory microcosm data.     

Modeling Abundance Index Data from Anuran Calling Surveys

Abstract:  Evaluation of anuran populations is commonly based on calling surveys that report categorical abundance index data. I present a statistical model for abundance index data that are observations representing ordered abundance classes (e.g., none, some, many). The proposed model provides a formal treatment of detection probability, factors that affect detection, and variation in abundance. The model can be viewed as a generalization of that proposed by MacKenzie et al. (2002) for estimating site-occupancy rates in that it allows for more than two abundance classes. Because the abundance distribution is characterized by multiple abundance classes, it may be more sensitive to subtle changes in the underlying abundance that may go undetected with simple occupancy estimates under which sites are characterized merely as occupied or not. The method is most immediately applicable to surveys of anurans in which index data related to the intensity of calling activity are collected. I applied the proposed method to calling index data from the green frog (  Rana clamitans ) collected as part of the North American Amphibian Monitoring Program. The best model indicated considerable variation in detectability over time and in response to temperature. The resulting adjusted (for detectability) abundance-state distribution demonstrates the negative bias in abundance state obtained from simplistic summaries of calling index data that disregard these sources of variation in detectability.     

Probabilistic indicators of atmospheric transport for regional monitoring and emergency preparedness systems

In this paper, following a methodology developed within the "Arctic Risk" Project of the Nordic Arctic Research Programme, several probabilistic indicators to evaluate the risk site possible impact on the geographical regions, territories, countries, counties, cities, etc., due to atmospheric transport from the risk site region were suggested. These indicators-maximum possible impact zone, maximum reaching distance, and typical transport time-were constructed by applying statistical methods and using a dataset of isentropic trajectories originated over the selected nuclear risk site (Ignalina nuclear power plant, Lithuania) during 1991-1996. For this site, the areas enclosed by isolines of the maximum possible impact zone and maximum reaching distance indicators are equal to 42 x 10(4) and 703 x 10(4) km(2), respectively. The maximum possible impact zone's boundaries are more extended in the southeast sector from the site and include, in particular, Latvia, Lithuania, Belarus, and several western regions of Russia. The maximum reaching distance's boundaries are twice more extended in the eastern direction from the site (reaching the Caspian Sea) compared with the western direction. The typical transport time to reach the southern territories of Sweden and Finland, northern regions of Ukraine, and northeast of Poland is 1 day. During this time, the atmospheric transport could typically occur over the Baltic States, Belarus, and western border regions of Russia, and central aquatoria of the Baltic Sea. Detailed analysis of temporal patterns for these indicators showed importance of the seasonal variability.     

Participatory Integrated Assessment in local level planning

The topic is introduced by a short but critical discussion of criteria and needs of Participatory Integrated Assessment (PIA) and participatory local planning. This paper depicts differences of participation in Integrated Assessment and in local level planning but provides also conditions and ideas how PIA can be used for local planning including implementation. A small review of PIA and participation in planning illustrates the relevance of PIA in a knowledge economy trying to adopt principles of good governance. A better incorporation of participatory research into local level planning seems to be crucial. The applicability of PIA in practices leading to participatory monitoring and evaluations are discussed. The outcomes of the paper show that possibilities exist for integrating PIA and participatory monitoring and evaluation into the implementation of the European Water Framework Directive (WFD). PIA adds local information to water management planning and supports individual learning processes. The setting up of such a monitoring and evaluation system may contribute towards a transparent implementation of the WFD, it enhances commitment of citizens towards local government planning and eventually it increases self-determination of citizens, a major objective of good governance.

No Net Loss of Fish Habitat: A Review and Analysis of Habitat Compensation in Canada

The achievement of No Net Loss (NNL) through habitat compensation has rarely been assessed in Canada. Files relating to 124 Fisheries Act Section 35(2) authorizations issued by Fisheries and Oceans Canada for the harmful alteration, disruption, and destruction of fish habitat (HADD) were collected and reviewed. Data extracted from these files were pooled and analyzed to provide an indication of the types of HADDs that have been authorized in Canada, what habitats have been affected, and what habitat management approaches have been used when compensating for HADDs and monitoring and ensuring the success of the compensation. Determinations regarding the effectiveness of habitat compensation in achieving NNL were made. Impacts to 419,562 m² of fish habitat from the 124 authorized HADDs were offset by 1,020,388 m² of compensatory habitat. Eighty percent of the authorizations had compensation ratios (compensation area:HADD area) of 2:1 or less, and 25% of the authorizations had a compensation ratio that was less than 1:1. In-channel and riparian habitat were the most frequently impacted habitats. Urban development and roads and highways resulted in the greatest areal loss of habitat. The compensation option that was most often selected was the creation of in-kind habitat. The mean duration of post-construction monitoring programs was 3.7 years. Determinations of NNL could only be made for 17 authorizations as a result of poor proponent compliance with monitoring requirements and the qualitative assessment procedures used by the monitoring programs. Adequate resources, proper training, and standardized approaches to data management and monitoring programs are required to ensure that the conservation goal of NNL can be achieved in Canada.     

Volunteer Environmental Monitoring and the Role of the Universities: The Case of Citizens' Environment Watch

Universities can provide a stable home for launching collaborative community research projects. Citizens' Environment Watch (CEW), an environmental monitoring initiative based at the University of Toronto, has made significant contributions to environmental education and stewardship in Ontario, Canada. Following dramatic cuts in provincial monitoring programs, citizens and youth have used chemical parameters and biological indicators to gauge water and air quality, and to identify areas requiring remediation and pollution prevention efforts. The relationship of Citizens' Environment Watch to government agencies, funders and other grassroots environmental groups has evolved over the past 5 years as CEW attempts to remain effective without taking on the investigative and enforcement roles to support the regulatory enforcement that has been largely abandoned by government. We explore the challenges inherent in developing and maintaining a volunteer organization that carries out rigorous and useful scientific work and we outline the ability of a university to help overcome these critical challenges. Finally, we present lessons learned for the benefit of other citizen and youth monitoring projects.
