The Economics Of Agricultural Water Productivity In The Blue Nile, Imeshi Weerasinghe, James Booker, Wim Bastiaanssen, Lisa-Marie Rebelo, Ann Van Griensven

International Congress on Environmental Modelling and Software

Agricultural Water Productivity (AWP) is often simplified as the ‘crop per drop’, described as the output in terms of yield or biomass per unit of water input. This purely physical measure of Water Productivity (WP) using only a single factor input (water) does not consider: (1) the level of other inputs used in conjunction with water, (2) the opportunity cost of water as an input, (3) the value of the output and (4) the costs of production for different crops. This study presents a justification and methodology for incorporating these factors into WP indicators. The application of these extensions to …

Using Scenario Analysis To Investigate Uncertainty In Water Resource Management, Baihua Fu, Joseph Guillaume, Mike Asher, Tony Jakeman

International Congress on Environmental Modelling and Software

Water resource management is a challenging task due to the complexity and uncertainty of the environmental systems and challenges of addressing multiple stakeholder perspectives. A crucial issue is therefore in specifically understanding if and how we can make decisions under such deep uncertainty.

We examined this issue in a case study which estimates groundwater sustainability, farm profit and ecological outcomes of many drivers (e.g. climate change, water policy, farm practices). An integrated model was developed for this purpose. It encompasses a surface and groundwater model, water allocation rules, a farm decision and crop model and an ecology model. Scenarios were …

Explicit Cost Accounting For Adaptation, Mitigation And Ecosystem Service Provision In Agriculture, Franz Sinabell, Karin Heinschink, Christoph Tribl

International Congress on Environmental Modelling and Software

Farmers, policy makers and scientists are well aware of this problem: obtaining sound cost information for climate change adaptation and mitigation measures in agriculture or ecosystem service provision by agriculture is burdensome. In most cases, data sets are developed for a specific region with a given set of management variants for a baseline period. Adapting such information to another region or adjusting costs to expected future price scenarios requires additional efforts and frequently done an ad-hoc and case by case. A new tool is presented that can be used to identify and analyze the entangled effects of future climate and …

An Agent-Based Model Of Jordan Highland Farmer Decision Making, Phil Selby, Josue Medellin-Azuara, Christian Klassert, Jim Yoon, Julien Harou

International Congress on Environmental Modelling and Software

We build a hydro-economic behavioural model of groundwater irrigated agriculture to help understand and analyse the impact of institutional and biophysical changes on land and water use in the Jordan Highlands. The model sits within a Multi-Agent-Simulation (MAS) framework representing the physical and institutional components of the wider national water resources system, which are being modelled by an interdisciplinary team, including a tanker water market and a groundwater model which interact with the farmer model. The MAS is designed to evaluate climate change scenarios and policy interventions to test whether reform of institutional rules that govern water usage in Jordan …

Agenda: 2010 World Energy Justice Conference: Emerging Solutions For The Energy Poor: Technological, Entrepreneurial And Institutional Challenges, University Of Colorado Boulder. Center For Energy & Environmental Security, Colorado Journal Of International Environmental Law And Policy

2010 World Energy Justice Conference (November 5)

This conference is a sequel to the 2009 World Energy Justice Conference (WEJC 2009) which began examining ways of mainstreaming safe, clean, and efficient energy for the world's Energy Poor (EP). The EP number two and a half billion people living on less than $1-2 a day who have no access to modern energy services. WEJC 2010 more fully develops these themes. WEJC 2010 will explore how the next round of global warming meetings in Cancun could design new flexibility mechanisms that give credits, for example, for the reduction of black carbon by the adoption of cookstoves, and embrace small …

Rainwater Harvesting Pilot Project Report, Liam Mccarton, Sean O'Hogain, Anna Reid, Niamh Mcintyre, Jenny Pender

Reports

The rainwater harvesting pilot project was commissioned by the National Rural Water Monitoring Committee in 2005 to assess the feasibility of supplementing treated mains water used for non-potable purposes. The project involved the design, installation, commissioning and monitoring of rainwater harvesting facilities in a rural housing development in County Carlow and in a 250-acre livestock farm in County Meath. Construction was carried out between 2005-2007.
