The river basin management approach in the Syr Darya basin fragmented after the disintegration of the Soviet Union. However, this approach had already created dependencies between riparian states, such as transboundary water control infrastructure. At the national level, these states hardly cooperate, but at the province and district level, especially in the Ferghana Valley, which is shared by Kyrgyzstan, Tajikistan, and Uzbekistan, cooperation continues. This paper analyzes transboundary cooperation in the Ferghana Valley.

Using models to bridge the gap between land use and algal blooms: An example from the Loweswater catchment, UK

Journal Articles & Books
Diciembre, 2012

The goods and services that lakes provide result from complex interactions between meteorology, hydrology, nutrient loads and in-lake processes. Hydrology and nutrient loads are, in turn, influenced by socio-economic factors such as human habitation, water abstraction and land-management, within their catchments. Models provide a means of linking these different domains and also of forecasting and evaluating the effects of different management scenarios on lakes.

River basin closure: Processes, implications and responses

Journal Articles & Books
Diciembre, 2010

Increasing water withdrawals for urban, industrial, and agricultural use have profoundly altered the hydrology of many major rivers worldwide. Coupled with degradation of water quality, low flows have induced severe environmental degradation and water has been rendered unusable by downstream users. When supply of water falls short of commitments to fulfil demand in terms of water quality and quantity within the basin and at the river mouth, for part or all of the year, basins are said to be closing.

Transactions Cost Approach to the Theoretical Foundations of Water Markets

Journal Articles & Books
Diciembre, 2009

Water marketing is often cited as a means of alleviating the stresses attached to allocation of water use. Frequently, marketing is suggested in a context that implies substitution of competitive markets for the allocation based on the prior appropriation doctrine. This study examines water marketing from the perspective of a transactions cost approach to the private and broad social agreements (contracts) that support water allocation. It examines the major behavioral challenges faced by any contract, and the alternative approaches to those challenges, with respect to water allocation.

Evapotranspiration estimation based on MODIS products and surface energy balance algorithms for land (SEBAL) model in Sanjiang Plain, Northeast China

Journal Articles & Books
Diciembre, 2013

In this study, the Surface Energy Balance Algorithms for Land (SEBAL) model and Moderate Resolution Imaging Spectroradiometer (MODIS) products from Terra satellite were combined with meteorological data to estimate evapotranspiration (ET) over the Sanjiang Plain, Northeast China. Land cover/land use was classified by using a recursive partitioning and regression tree with MODIS Normalized Difference Vegetation Index (NDVI) time series data, which were reconstructed based on the Savitzky-Golay filtering approach.

Managing the Florida Everglades: Changing values, changing policies

Journal Articles & Books
Diciembre, 2006

The Florida Everglades is a ecologically rich land and water environment that has gone through three phases. In the first phase, a small indigenous population drew its low-impact livelihood from the Everglades. During the second phase, the Everglades was drained, plowed, developed, and seriously damaged, while helping to support a booming South Florida economy. During the third phase, earlier alterations of water flow patterns in a part of the original Everglades are being restored and agricultural impacts are being mitigated.

Methods and approaches to support Indigenous water planning: An example from the Tiwi Islands, Northern Territory, Australia

Australia

Indigenous land owners of the Tiwi Islands, Northern Territory Australia have begun the first formal freshwater allocation planning process in Australia entirely within Indigenous lands and waterways. The process is managed by the Northern Territory government agency responsible for water planning, the Department of Natural Resources, Environment, The Arts and Sport, in partnership with the Tiwi Land Council, the principal representative body for Tiwi Islanders on matters of land and water management and governance.

Combining gray system and poroelastic models to investigate subsidence problems in Tainan, Taiwan

Journal Articles & Books
Diciembre, 2015
Taiwan

Tainan, located in southwestern Taiwan, is a high-risk region for flooding and climate change effect and has a potential for future heavy rains. Groundwater pumping for aquaculture and irrigation along the coastal plain of Tainan is monitored due to subsidence. Predicting future subsidence and understanding the effect of climate change on subsidence can assist with regard to the planning and management of water and land resources in the early stages of subsidence, whose possible damage can thus be avoided.

Game changers for irrigated agriculture—do the right incentives exist?

Game changers to achieve sustainable intensification of agriculture are possible in the irrigation sector and they focus mainly on getting more with less. There is, however, still a long way to go to replicate, adapt and develop approaches to take such ideas to scale and increase productivity within existing agricultural water management contexts.
