Modern economy increasingly depends on effective knowledge management – i.e. acquiring, generating, distributing and applying of knowledge in modern societies and organizations. In such circumstances more and more visible becomes a crisis of real leadership, or even, quite often, lack of leadership. We often observe how formal leaders of different kind, so important until recently, are rapidly losing...
Under arid (dryland) conditions where the usual rain amounts fall short of the moisture deficit in the surface layers, the occurrence of surface flows is a necessary pre-requisite for the occurrence of groundwater recharge at selected infiltration sites. These surface flows at the same time nourish a variety of plants and biota along the flowpaths, which in turn affect both the quality and quantity...
The ecohydrology of an area or region is determined by climate, geomorphology, plant cover/biota dynamics and anthropogenic modifications. By understanding these factors, the potential exists for the application of Phytotechnologies to increase plant biomass and to regulate nutrients and water dynamics, thereby increasing ecosystem carrying capacity, resilience and functionality. This can lead to...
A drastic land use change and environmental degradation take place in Southern Andean Patagonia steep watersheds, especially upstream the urbanized areas. The paper presents a synthesis of environmental degradation assessment due erosion at Trabunco-Quitrahue watershed, near the top ski resort of San Martín de los Andes (Argentina). In order to evaluate the degradations processes, a combination of...
Ecohydrology is more than just hydrology and ecology combined. It is functional to its best only, if science, engineering and construction, public administration and political decision assist each other in an integrated scheme and on a common scale. The UNESCO Biosphere Reserve “Lobau”, part of the Danube National Park today, is dependant on all four aspects for its sustained existence. The integrated...
The following areas of research related to the climate\water resources interface may be identified: detecting changes in atmospheric and hydrological variables by means of measurable indicators, including paleohydrological data; assessing sensitivity of land surface processes to climate characteristics; analyzing implications of climate change on regional water supply and demand; assessing the impact...
Ecohydrology had its origins in the Ecotone activity of the man and the Biosphere programme, but continues and expands today under the joint activity on water and Ecosystems promoted by UNESCO. The future role for Ecohydrology as an integrative discipline is clear when the emerging issues of Ecosystem management for sustainability are considered. The complementary efforts of the World Network of Biosphere...
Changes in hydro-geological pattern of the river Brahmaputra, due to changes in topography, altitude, precipitation, and soil conditions, has resulted in zonation of the river into five major types of habitats that influence the distribution of fish biota. The erratic nature of water discharge, high rates of erosion and siltation, and habitat destruction have negative impacts on the commercial fishery...
In the face of increasing pressure on freshwater resources, there exists an urgent need for new practical tools to achieve their sustainable management. Sustainable water resources and ecosystem services at the global scale can be achieved by two types of actions: first, the reduction of energy and material use per capita — expressed by the UNEP Concept of Ecoefficiency and second, by enhancement...
Ecohydrology research projects undertaken, within the framework of the International Hydrological Programme, in Latin America and the Caribbean are presented, together with contact details of the participants. These include investigations by national research organizations in Argentina, Bolivia and Brazil, as well as collaborative projects involving Brazilian researchers and colleagues from Germany,...
Ecohydrology in Australia is moving towards solving practical management problems by linking environmental, social and economic factors. The River Murray Wetland Rehabilitation Project is demonstrating the ecohydrological approach to manage local resources with the involvement of communities. On-ground projects aim to restore key elements of the natural hydrological regime to repair damaged wetland...
Evaluation and assessment of fresh and inland water quality at the regional and global scales is not a simple task. UNEPs GEMS/Water has operated a comprehensive freshwater quality monitoring and assessment programme for over 20 years and is the only such global programme. GEMS/Water operates by inviting national governments to provide water quality data from their water quality monitoring programmes...
The key to ecological revitalisation of river floodplains is improving the water regime, since this very important abiotic factor has undergone serious deteriorations due to anthropogenic effects. The desired improvement can be achieved by transforming the natural water conveyance infrastructure of the river-floodplain system in an appropriate manner. The proposed revitalisation has been tested on...
The La Plata River Basin is one of the largest international watersheds in the world (its area is about 3 million km2), rich in water and other natural resources that are essential for the economic development of the five countries that share its territory: Argentina, Bolivia, Brazil, Paraguay and Uruguay. Together with the development of large reservoirs for energy and other water uses, extensive...
There have been no ubiquitous, and unanimously accepted, definitions of the notions of ecohydrology and sustainable development. Aside from the interpretation by the UNESCO IHP-V Projects 2.3/2.4, there exist other ways, in which the terms “ecohydrology” and “hydroecology” are understood. Also several competing definitions of the notion “sustainable development” are available. Yet, a robust finding,...
