Damage estimation on agricultural crops by a flood

SPIE Proceedings, 2011
Southeastern Mexico, particularly Tabasco's flatlands which experienced a severe flood in 2007, was used as a case study for testing a methodology for the estimation of direct damage looses on agricultural crops by flooding. We proposed an accurate delineation of agricultural lands of multispectral images (SPOT-5) which consist on ensemble ...

Flood Damage to Rice Crop in Bangladesh

Geographical Review, 1993
EVERY year, almost one-third of Bangladesh is flooded. However, because of topographical characteristics, the regions of the country experience varied degrees of flooding; some parts may be under deep floodwater, others unaffected. Flooding is beneficial only within certain limits of timing, duration, and magnitude (Paul 1984; Rasid and Paul 1987).

Damage to Crops and Other Plants

1983
Damage to crops caused by gaseous pollutants, like that of trees, can be acute or have chronic/growth effects. However, unlike trees, there is little evidence for any acute damage. Identification of yield effects, by their very nature, must rely upon constructed experiments, otherwise other factors such as climate, soil or agricultural management mask ...

Crop Damage: The Hail Size Factor

Journal of Applied Meteorology, 1996
Abstract Between 1986 and 1992 a research project was developed and carried out on hail climatology and the economic repercussions of hail on agriculture in Leon (northwestern Spain). A target area with an extent of 6825 km2 was defined, within which a network of meteorological observers was established at an average density of 1 per 17 km2.

Crop Damage from Sulfur Dioxide

Journal of Farm Economics, 1966
The pollution abatement problem has always been in part a measurement problem. In order to properly evaluate the full extent of pollution damage to crops objective methods for determining the losses are necessary. A method has been reviewed for determining the losses due to SO/sub 2/.

Hailfall and crop damage in central Alberta

The Journal of Weather Modification, 1975
Hail occurs within a 90-mile radius of Red Deer on an average of 61 days between 15 May and 15 September. A summary is reported by months of various hail parameters. The season reaches its peak in July when the probability of a hailday is at a maximum of 66%. The probability gradually falls off in August and by September the  season effectively is over.

Damage to glasshouse crops by over‐manuring

Journal of the Science of Food and Agriculture, 1952
AbstractSevere damage to lettuce involving tip‐burn of the leaves, wilting and death has occurred in several tomato glasshouses in west Scotland. Soils from such houses lose their capacity to cause damage if their soluble‐salt content is reduced by leaching or liming.

Developments in Estimation of Damages to Crops

Using spatially desegregated data on measures of pollution to derive economic damage estimates, the main purpose of the book is to gauge the environmental damage sustained as a result of economic activities and to offer an insight into how the information generated can be used in conjunction with conventional economic accounts.

Exhaust fumes seriously damage crops

Trends in Plant Science, 2000
John Ollerenshaw’s (University of Newcastle upon Tyne, UK) results from a 10-year study show that because of the effect of exhaust fumes and ozone, the annual UK wheat yield is dropping by ∼13% a year, oil seed rape (Brassica napus) yield is falling by ∼14% a year and white clover by ∼33% a year.
