Decisores de los gobiernos, inversionistas o productores locales on frecuencia subestiman el valor de las aguas subterráneas en la economía y para el desarrollo económico, ya que asumen que los manantiales y pozos, de los cuales dependen, continuarán abasteciéndolos con agua dulce de alta calidad para siempre. De seguir con estos supuestos, se perderán los beneficios del agua subterránea para el desarrollo. Cuando la gestión de las aguas subterráneas es sostenible, sus contribuciones se reflejan en múltiples dimensiones del desarrollo sostenible. La gestión sostenible de las aguas subterráneas puede asegurar el abastecimiento de agua resiliente al clima para ayudar a cumplir las metas de seguridad alimentaria, desarrollo energético y acceso al agua potable. Puede abastecer de agua a las ciudades sostenibles y la industria. La gestión sostenible de acuífe...

This paper addresses how decisions on environmental flows should not just be determined directly from sci-entific data but requires active learning and communication between stakeholders from the inception of an assessment to the implementa-tion. Informed decision making requires that the decision maker un-derstands what the outputs of an environmental flows assessment are and how they can be used to aid in deciding future water allocations. This type of approach to environmental flows assessment is a multi-step process that provides a bridge between the science and policy realms. Cooperative communication coupled with action learning can ensure that the knowledge imparted by scientists to inform deci-sion makers will also be informed by the needs of the decision mak-ers themselves.

Competition for diminishing water resources has led to tensions between the various stakeholders within the basin. Together with the government of Tanzania and donor partners, WANI has responded to this crisis by supporting the implementation of Integrated Water Resources Management (IWRM). This sought to bring together a variety of stakeholders by creating platforms for dialogue and encouraged collaboration towards a common goal. The Pangani River Basin Management Project has generated technical information and developed participatory forums, mainstreamed climate change, supported the equitable provision and wise governance of freshwater for livelihoods and environment for current and future generations. This case study describes the situation, activities taken, and results achieved during this process.

Environmental flows are effectively a balance between water resources development and the need to protect freshwater-dependent ecosystems. WANI has contributed to environmental flow assessments in river basins in Asia, America, and Africa over the last 10 years with the aim of reducing environmental impacts and increasing the benefits of river basin development. Through scaling-up, lessons learned have been mainstreamed into integrated water resources management (IWRM) allowing for the capacity building of existing legislation and the establishment of new, appropriate legislation on environmental flows. This influence on IWRM and water policy has resulted in better water resources management.

How these changes reflect water management decisions and what can be done to minimize climate change impacts remains unclear. This paper summarizes and extends the workshop outcomes on ‘Climate Change Impacts on Watershed Management: Challenges and Emerging Solutions’ held at the IWA World Water Congress and Exhibition, Montréal, 2010, hosted by the IWA Watershed and River Basin Management Specialist Group. The paper discusses climate change impacts on water management of freshwater ecosystems and river basins, and illustrates these with three case studies. It is demonstrated through the case studies that engagement of relevant stakeholders is needed early in the process of building environmental flows and climate change decision-making tools, to result in greater buy-in to decisions made, create ...

There is growing interest in low cost sanitation solutions which harness natural systems. However, it can be difficult for wastewater utility managers to understand under what conditions such nature-based solutions (NBS) might be applicable and how best to combine traditional infrastructure, for example an activated sludge treatment plant, with an NBS such as treatment wetlands. There is increasing scientific evidence that treatment systems with designs inspired by nature are highly efficient treatment technologies. The cost-effective design and implementation of ecosystems in wastewater treatment is something that exists and has the potential...

Hydrogeological data indicates that a light non-aqueous phase liquid (LNAPL) plume extends approximately 400m downgradient from the source, and dissolved petroleum hydrocarbons (PHCs) extend a further 300 m downgradient. The LNAPL and dissolved hydrocarbons consists of weathered diesel that contains a higher proportion of heavier PHCs, such as total extractable hydrocarbons (TEH; C 11 -C 30 ), which tend to be recalcitrant.

A... more Ecosystem services are increasingly recognised as important assets for sustainable development. A close interdependency between ecosystem services and groundwater exists. On the one hand, these services depend directly on the functioning of ecosystems such as wetlands, forests, lakes and coastal areas which derive freshwater for their functioning from sub-surface water, including groundwater. On the other hand, groundwater resources are dependent on recharge through infiltration of rainwaters. The rate and quality of recharge is amongst others determined by the type and spatial configuration of ecosystems. The close linkages between groundwater and ecosystem services are often not recognised and under valued. In this paper these relationships are clarified and an indication of their value is provided. Furthermore, a number of options for sustainable management of ecosystems services and groundwater are put forward.
