New Publications involving WEAP Jack Sieber jsieber <a href="mailto:jack.sieber@sei-us.org">jack.sieber@sei-us.org</a>
I just posted two new papers on the WEAP Publications page
(http://www.weap21.org/index.asp?doc=16). If you have written or know
of other publications involving WEAP, please let me know.

Application of the Water Evaluation And Planning (WEAP) Model to Assess
Future Water Demands and Resources in the Olifants Catchment, South
By Roberto Arranz and Matthew McCartney
Working Paper 116, International Water Management Institute (IWMI),

Being able to assess the ability of a catchment to satisfy potential
water demands is crucial for water resource planning. In this study, a
scenario analysis approach was used in combination with the Water
Evaluation and Planning (WEAP) model, to assess the impacts of possible
future demands on the water resources of the Olifants River catchment,
South Africa. The WEAP model was used to simulate water demand in five
different sectors; rural, urban, mining, commercial forestry and
irrigation. For each scenario the model provided data on unmet demands
and the impacts on river flow. The implications of construction of new
water infrastructure and improved demand management were assessed. The
study illustrates the value of scenarios linked to simple modeling
tools, to provide insight for resource planning.

Public Policies for Groundwater Conservation: A Vulnerability Analysis
in Irrigation Agriculture
By Consuelo Varela-Ortega1, Paloma Esteve1, Sukaina Bharwani, Thomas E.
Report presented at CAIWA 2007: International Conference on Adaptive &
Integrated Water Management, Coping with complexity and uncertainty,
Basel, Switzerland, November 2007.

Increasing competition for water resources is becoming a major social,
economic and environmental problem in many arid and semiarid regions
worldwide. Spain is the most arid country in Europe and water use as
well as water depletion and environmental degradation have slowly become
a matter of social concern. Water issues and region-based rivalry for
water are progressively high in the political agendas and public
debates, as societal concern towards the nation's distribution of water
property rights and towards environmental issues expand progressively in
the Spanish society.

In the Upper Guadiana basin (UGB), situated in Spain's inland southern
region of Castilla-La Mancha, groundwater has been the major driver for
developing irrigated agriculture and hence for sustaining thriving rural
livelihoods. In the last decades, the ever-mounting expansion of
groundwater irrigated agriculture has been fostered by yield-based
Common Agricultural Policy (CAP) programs, the development of modern
hydrology and irrigation technologies and private initiative
(Varela-Ortega, 2007a, Llamas and Martinez-Santos, 2006). Easy access,
low infrastructure costs and high profitability, have encouraged
individual farmers to invest in ground water irrigation transformations
that have ensued impressive welfare achievements of a former stagnated
region. However, uncontrolled irrigation development has led to the
over-exploitation of the large Western La Mancha aquifer and the
deterioration of the valuable internationally reputed Ramsar-catalogued
wetlands of 'Las Tablas de Daimiel'.
