Forest and Floods

  pages={87 - 99}
Abstract Evidence is presented to show that there is a growing disparity between public perception and scientific evidence relating to the causes of floods, their impacts, and the benefits of mitigation measures. It is suggested that this disparity has arisen through the extensive promotion of certain land uses and engineering interventions by vested interest groups in the absence of any effective dissemination of the scientific evidence which may allow a contrary view. It is believed that this… Expand
Global evidence that deforestation amplifies flood risk and severity in the developing world
With the wide acceptance of forest-protection policies in the developing world comes a requirement for clear demonstrations of how deforestation may erode human well-being and economies. ForExpand
An empirical assessment of which inland floods can be managed.
It is shown that landscape features affect magnitude and duration of only those floods with return periods ≤10 years, which suggests that larger floods cannot be managed effectively by manipulating landscape structure. Expand
Land Use Impacts on Water Resources – Science, Social and Political Factors
Public perceptions of land-use impacts on water resources are important because they influence formal environmental policies and popular attitudes about land use. For example, upland agriculture andExpand
Discussion of the article: Calder, I. R. & Aylward, B. (2006) Forest and Floods: Moving to an Evidencebased Approach to Watershed and Integrated Flood Management
Calder & Aylward (2006) argue that there is a plethora of “misinformation, misperceptions and myths“ related to the “relationships between forests, trees and land-use activities on one hand andExpand
Forest–flood relation still tenuous – comment on ‘Global evidence that deforestation amplifies flood risk and severity in the developing world’ by C. J. A. Bradshaw, N.S. Sodi, K. S.‐H. Peh and B.W. Brook
In a recent paper in this journal, Bradshaw and colleagues analyse country statistics on flood characteristics, land cover and land cover change, and conclude that deforestation amplifies flood riskExpand
Catastrophic flood and forest cover change in the Huong river basin, central Viet Nam: a gap between common perceptions and facts.
Forest management policies and programs, shaped on the common assumption that forest degradation in the upland is the main cause of catastrophic flood in the downstream areas, should be reassessed to avoid unnecessary strain on upland people. Expand
Forests and floods: A new paradigm sheds light on age‐old controversies
[1] The science of forests and floods is embroiled in conflict and is in urgent need of reevaluation in light of changing climates, insect epidemics, logging, and deforestation worldwide. Here weExpand
The value of the flood control service of tropical forests: A case study for Trinidad
To date there have been only few case studies that specify how hydrological processes regulated by forests convey into benefits for society. The objective of this paper is to analyse the relationExpand
Highlands management in a flood-prone watershed: Does reflexive reciprocity make a difference?
Abstract Poor levels of reciprocity (or “upstream/downstream” situations) are believed to discourage responsible actions and thus make sustainability harder to achieve. This paper presents a studyExpand
Forest cover change and flood hazards in India
Abstract Forests provide numerous environmental services such as watershed protection, nutrient cycling, pollution control, climatic regulation, carbon sequestration, flood mitigation, and protectionExpand


Forest roads: a synthesis of scientific information.
Effects of roads in forested ecosystems span direct physical and ecological ones (such as geomorphic and hydrologic effects), indirect and landscape level ones (such as effects on aquatic habitat,Expand
The domestic benefits of tropical forests: a critical review.
It is noted that the quantifiable benefits of forest preservation in providing hydrological services and non-timber forest products are highly variable and the need for financing conservation from the Global Environmental Facility or other global sources is emphasized rather than placing the burden on domestic resources.

What Are the Impacts of Himalayan Deforestation on the Ganges-Brahmaputra Lowlands and Delta? Assumptions and Facts
Several serious problems impede the task of determining the biophysical impacts of deforestation in the mountainous uplands on the lower reaches of major river systems. Three of these are discussed:Expand
Studies of the impact of forests on peak flows and baseflows: a European perspective
Most of the scientific studies of forest impacts on stream flows have been conducted in North America. Many were primarily concerned with felling effects. These have generally found forests to beExpand
Science and the Desiccationist Discourse of the 20th Century
This essay explores the progression of theoretical models and empirical research linked to the understanding of the capacity of forested systems to regulate the hydrological regimes of a given area and suggests a diversity of viewpoints with regard to the climatic and protective capabilities of forests gradually gave way to a more unified and highly alarmist 'desiccationist' discourse by the middle of the 20th century.

Flood disasters: lessons from the past—worries for the future
Flood disasters account for about a third of all natural disasters throughout the world (by number and economic losses) and are responsible for more than half of the fatalities. Trend analyses revealExpand
This paper introduces a special edition of Mountain Research and Development on integrating natural and social envi- ronmental science. In recent years, environment and development research has beenExpand
Forests and floods in the eastern United States
Our purpose is to examine in detail the influence of the present-day forest on flood runoff and sedimentation. Forests and flood discharge wiI1 be our dominant concern; sedimentation by and large isExpand
Effects of Forest Clear‐Felling on the Storm Hydrograph
Earlier speculation that evapotranspiration from forests and the consequent soil water deficits under forests are factors in the production of floodwaters was verified by a paired watershedExpand
History of forest hydrology
Abstract Hydrology as a science and a technology is examined, as are some of the myths on the role of forests in hydrology and water resources. The history of catchment area research is traced, inExpand
