Reports & Research
Diciembre, 2014
Ecuador

La aprobación de la Ley de Aguas por parte de la Asamblea Nacional no disminuyó los ánimos de los dirigentes de la marcha indígena que rechazan esta normativa y otros puntos de la vida nacional, al considerar que no se han tomado en cuenta sus criterios planteados en la consulta prelegislativa. Hoy cumplen el séptimo día de marcha.

Depoliticizing land and water “grabs” in Colombia: the limits of Bonsucro certification for enhancing sustainable biofuel practices

América central
América del Sur

As concerns heighten over links between biomass production and land grabs in the global south, attention is turning to understanding the role of governance of biofuels systems, whereby decision-making and conduct are not solely determined through government regulations but increasingly shaped by non-state actors, including multi-stakeholder initiatives (MSI). Launched in 2005, Bonsucro is the principal MSI that focuses on sustainability standards for sugar and sugarcane ethanol production.

Texas environmental flow standards and the hydrology-based environmental flow regime methodology

Journal Articles & Books
Diciembre, 2014

In 2007, the Texas legislature created a program to identify environmental flow standards statewide through the coordinated efforts of scientific and stakeholder groups and rulemaking by the Texas Commission on Environmental Quality. To aid in this task, a Hydrology-based Environmental Flow Regime (HEFR) method was developed that combines a suite of user-customizable hydrologic statistics with an implementation framework. Following the concepts of the Natural Flow Paradigm, the methodology includes the separation of a long-term hydrograph into key flow components (e.g.

Factors Influencing the Stream‐Aquifer Flow Exchange Coefficient

Journal Articles & Books
Diciembre, 2014

Knowledge of river gain from or loss to a hydraulically connected water table aquifer is crucial in issues of water rights and also when attempting to optimize conjunctive use of surface and ground waters. Typically in groundwater models this exchange flow is related to a difference in head between the river and some point in the aquifer, through a “coefficient.” This coefficient has been defined differently as well as the location for the head in the aquifer.

Stakeholders’ Responses to the Use of Innovative Water Trading Systems in East Anglia, England

Journal Articles & Books
Diciembre, 2014

It is widely recognised that the current abstraction licensing system in England needs to be reformed to meet the challenges of future environmental flow requirements, likely increases in water demands and climate change. The UK Government has committed to the reform of the abstraction regime in England and work is underway, including the Welsh Government, to assess the impacts of different reform options, working closely with stakeholders.

Irrigation Access and Vulnerability to Climate‐Induced Hydrological Change in the Ecuadorian Andes

Journal Articles & Books
Diciembre, 2014

Climate change is projected to substantially alter the hydrological cycles of mountainous regions, with pronounced consequences for the human settlements in these areas. Because projections of climatic changes and their environmental and societal impacts in local settings are uncertain, policies to reduce vulnerability and strengthen adaptation should be informed by ongoing processes in sites already exposed to climatic variability and change.

Equity in bulk water allocation: the case of the Mahaweli Ganga Development Project in Sri Lanka

Sri Lanka

This article evaluates the equity performance of bulk water allocation as an irrigation management strategy in the Mahaweli Ganga Development Project, Sri Lanka. Through semi-structured interviews with farmers and irrigation officials, the study collected local perceptions using seven indicators: water rights; decision-making process; contribution of resources for irrigation maintenance; water allocation rules; actual water distribution; information sharing; and conflict resolution.

Estimating Water Rights Demand and Supply: Are Non-market Factors Important?

Chile

Water rights demand and supply in the upper Maipo river basin (Metropolitan Region of Chile) are estimated for the period July 1998 to June 2003, as well as a reduced form model for the equilibrium water rights price based on supply and demand determinants, as well as characteristics of the participating agents such as the economic sector of each agent and their individual market experience. Results show that the main participants in the market are both agriculture and real estate sectors (developers); agriculture buying 57� % and selling 68� % of transactions.

Institutional response to external disturbances in spate irrigation systems of Punjab, Pakistan

Pakistán

Social ecological systems (SESs) – spate irrigation system in our case – operate under an environment of stress due to several external and contextual factors. Spate irrigation systems are more complex due to uncertain flows and can exhibit unexpected changes due to novel shocks. Therefore, actions directed at enhancing robustness to a particular set of disturbances can trigger changes in ecological dynamics that may, in turn, alter the set of disturbances faced by irrigators.

Forecast of Natural Aquifer Discharge Using a Data‐Driven, Statistical Approach

Journal Articles & Books
Diciembre, 2014

In the Western United States, demand for water is often out of balance with limited water supplies. This has led to extensive water rights conflict and litigation. A tool that can reliably forecast natural aquifer discharge months ahead of peak water demand could help water practitioners and managers by providing advanced knowledge of potential water‐right mitigation requirements. The timing and magnitude of natural aquifer discharge from the Eastern Snake Plain Aquifer (ESPA) in southern Idaho is accurately forecast 4 months ahead of the peak water demand, which occurs annually in July.
