ECOSYSTEM SERVICE ASSESSMENT IN AGRICULTURAL WATERSHED BY USING TOPMODEL

Spatial interactions among ecosystem services in an urbanizing agricultural watershed.

Understanding spatial distributions, synergies, and tradeoffs of multiple ecosystem services (benefits people derive from ecosystems) remains challenging. We analyzed the supply of 10 ecosystem services for 2006 across a large urbanizing agricultural watershed in the Upper Midwest of the United States, and asked the following: (i) Where are areas of high and low supply of individual ecosystem s...

Modeling the Supply of Sediment Retention Ecosystem Service (Case study: Eastern Part of Gorgan-Rud Watershed)

Ecosystem services are benefits that people obtain from ecosystems. Soil retention is one of the most important ecosystem services. The capacity of ecosystem to maintain soil can be estimated by quantifying this services. In this study, version 3.0.0 of the InVEST software was used to map this ecosystem service in the eastern part of Gorgan-Rud watershed. The InVEST model employs the Universal ...

Ignoring Ecosystem-Service Cascades Undermines Policy for Multifunctional Agricultural Landscapes

Over and above food, agricultural landscapes provide citizens with crucial public-good ecosystem services, such as biodiversity conservation, cultural values, recreational opportunities, and food security. Because continuing agricultural intensification undermines the ability of landscapes to provide public goods, policies have been implemented to preserve landscape multifunctionality, but with...

Aquatic ecosystem assessment using exergy

The recent work is dedicated to the study of behaviour of exergy and structural exergy in physical models of aquatic ecosystems—mesocosms and microcosms and in Lake Baikal. The results of field experiments with mesocosms on Lake Baikal, containing natural plankton assemblage, and laboratory experiments with microcosms containing Daphnia magna and Chlorella vulgaris demonstrated decrease of the ...
