“…Yapp et al 2010). Terrestrial systems have a higher proportion of 'in situ' services in which the point of service provision is the same as the location of utilisation, making mapping more straightforward (Richmond et al 2007, Costanza 2008. Mapping of marine services may prove more difficult due to the diverse and spatially widespread functions that underpin them.…”

The ability to manage complex systems effectively must stem from simplifications of ecological knowledge. We present a technique called the 'Ecosystem Principles Approach' (EPA) as a progressive way of incorporating ecology into goods and services assessments. The EPA moves away from the complexity of ecosystem functions and focuses on general ecological principles. These principles more explicitly define key elements of system functioning, are not spatially or temporally confined, and can be utilised in assessment and decision-making processes. When applied to a coastal system in New Zealand, the EPA highlighted that services were primarily dependent on connectivity and that the maintenance of healthy intertidal areas was highly important for system functioning. The approach also demonstrated a separation between locations where ecosystem functions were generated and where services were valued. A high level of multi-functionality and connectivity between goods and services in marine coastal systems suggests services should be managed collectively rather than individually. The strength of the EPA is that it aligns to the principles of 'EcosystemBased Management'. This approach demonstrates how ecological information can be simplified into a format that can advise policy and better integrate with management. It highlights the need for greater trans-disciplinary integration of ecology and social science to better understand how human interactions result in critical community shifts and loss of resilience.

“…Microphytobenthos (MPB) assemblages can contribute up to 50% of estuarine primary productivity (Underwood and Kromkamp, 1999), providing important environmental services in terms of carbon and nutrient fluxes (Richmond et al, 2007). They also have critical roles in the food web, given that they represent an important food source, especially for deposit-and suspensionfeeding macrofauna , and in the stabilization of sediments (Paterson, 1989).…”

Keywords:Microphytobenthos Intertidal flats Temporal and spatial variability Mediterranean Climate NDVI MERIS/SPOT a b s t r a c tThe spatio-temporal variation of microphytobenthos (MPB) at the scale of a large estuary (Tagus estuary, Portugal) was studied using a combination of field and satellite remote sensing data during 2003. This is the first attempt to use remote sensing to study MPB in an ecosystem with a Mediterranean-like climate. Satellite pour l'Observation de la Terre (SPOT) and Medium Resolution Imaging Spectrometer (MERIS) images were used to map benthic microalgae through the application of a Normalized Difference Vegetation index (NDVI). A significant relationship between in-situ benthic chlorophyll a measurements and SPOT NDVI values was used to derive a map for biomass spatial distribution.At the scale of the whole intertidal area, NDVI time-series from 2003 revealed that MPB showed clear temporal variations, with lower values observed in summer compared to winter. This seasonal trend was found both in the SPOT and MERIS images and may be the result of extreme high temperatures that inhibit MPB growth. The main MPB biofilms were spatially stable through time at a large scale. Maximum NDVI values during the winter were found in the high shore with decreasing NDVI values towards the low shore. MPB light limitation at the lowest bathymetries is likely to occur in winter due to the high turbidity of Tagus . This study suggests striking differences in MPB seasonal patterns between the northern and southern European estuaries and stresses the need for ecophysiological approaches to investigate the role of thermo-and photo-inhibition as structuring factors for MPB biomass distribution.

“…Salman et al (2014), described the importance of shadow prices to assist farmers making investment decisions in developing alternative sources of water, such as groundwater pumping, water importation, or water conservation. Where the economic values of water are specified, these water shadow prices represent useful tools for identifying water policies (Rosegrant et al, 2000;Dopplera et al, 2002;Richmond et al, 2007).…”

The magnitude of water resources shortages in the Middle East represents an important factor in the stability of the region and it is a vital element in protecting sustained economic development in the region. This investigation addresses the ongoing challenge of water governance in Iraq by examining how profitability, at both the farm and basin levels, is affected by various water appropriation systems. Farmland irrigation in Iraq was evaluated using three water appropriation systems; upstream (UPR), downstream (DPR) and proportional (PSR) sharing rule. Their impacts on farm income under normal, dry, and drought water supply scenarios were evaluated using an irrigation water model coupled with a nonlinear programming (NLP) optimization model. As compared to UPR, PSR provided a 32% and 75% increase in total farm income for the Tigris River under dry and drought supply conditions, respectively. As compared to DPR, PSR provided a 47% and 83.5% increase in total farm income for the Euphrates River under dry and drought supply conditions, respectively.
