Agrometeorological Aspects Of Crop Production In Temperate Kashmir, Badrul Hasan
Agrometeorological Aspects Of Crop Production In Temperate Kashmir, Badrul Hasan
Drought Network News (1994-2001)
In our recent article on forecasting uncertain weather over temperate Kashmir (India) (Drought Network News, Vol. 9, No. 1, pp. 12–14), we tried to characterize the crop-growing environments by giving long-term means of various agrometeorological parameters (such as air temperature, relative humidity, precipitation, and hours of bright sunshine). Forecast analysis for changes in temperature and precipitation events indicated an overall reliability of about 50%. Changes in minimum temperature could be forecasted relatively more accurately than changes in maximum temperature. Precipitation events were more uncertain during summer (May to October), which happens to be an important season from the …
A Case Study Of The Deficit Spell Index For India’S Semiarid Delhi Region, K. K. Nathan
A Case Study Of The Deficit Spell Index For India’S Semiarid Delhi Region, K. K. Nathan
Drought Network News (1994-2001)
The Delhi region, the national capital region of India, is locked in by adjoining states like Uttar Pradesh and Haryana. Delhi has a characteristic continental type of climate, with extreme dryness, intensely hot summers, and dry cold winters. According to climatologists, this region is classified as semiarid tropical steppe. The monsoon rainfall is very erratic during June–September, which is the kharif crop-growing season. The monsoon breaks over the Delhi region between the first and second week of July and withdraws by the last week of September. The average annual rainfall is about 712.5 mm, of which 80% is contributed by …
Ndmc Conducting Regional Drought Planning Workshops
Ndmc Conducting Regional Drought Planning Workshops
Drought Network News (1994-2001)
The National Drought Mitigation Center is conducting a series of regional workshops, “Planning for the Next Drought,” around the country in 1997 and 1998. The first workshop was in Albuquerque, New Mexico, July 28–30. Plans are underway to conduct similar workshops in other regions. A second workshop will probably be held in Salt Lake City in late 1997, followed by workshops in the Southeast and Midwest in 1998. Because the workshops are sponsored by the U.S. Bureau of Reclamation, there is no registration fee.

Drought policy continues to be a topic of much discussion in the United States. On June 12, the Western Drought Coordination Council (WDCC) met for the first time and adopted a work plan for 1997–98. The WDCC is committed to improving drought management in the western states through mitigation and preparedness. It is hoped that this Council, representing a partnership between federal, state, local, and tribal government, will serve as a model for other drought-prone regions of the United States. Four working groups (preparedness and mitigation; monitoring, assessment, and prediction; response; and communications) established by the Council will meet in …

National Drought Mitigation Center Involved In Development Of Natural Hazards Map, Michael J. Hayes
National Drought Mitigation Center Involved In Development Of Natural Hazards Map, Michael J. Hayes
Drought Network News (1994-2001)
The National Drought Mitigation Center (NDMC) is involved in a project with several other agencies and organizations in Canada, Mexico, and the United States to develop a map of the major natural hazards that threaten North America. Work on the project began in February 1995. Since then, there have been three working group meetings, with the most recent meeting taking place in Guadalajara, Mexico, in February 1997. Project leaders include Dr. Chris Tucker (Emergency Preparedness Canada), Dr. Joe Golden (National Oceanic and Atmospheric Administration [NOAA]), Dr. Rosalind Helz (U.S. Geological Society [USGS]), and Dr. Mario Ordaz- Schroeder (Centro Nacional de …

Workshop On Drought And Desertification: Report On The Workshop And Recommendations, J. Lomas
Drought Network News (1994-2001)
The Workshop on Drought and Desertification was held in Israel from 26 to 30 May 1997. Forty-four participants from Africa, Asia, and Europe took part in the Workshop, which was sponsored by WMO. Three foreign experts provided in-depth analysis on drought and drought preparedness—Dr. O. Brunini (Campinas, Brazil), Prof. S. Mei (CAAS, Beijing, China), and Dr. D. Wilhite (University of Nebraska, USA), in addition to the Israeli lecturers.
Presentations by lecturers and discussions were conducted under the following four main headings:
1. Drought and Desertification Definitions.
2. Drought Causes and Management Response.
3. Drought Monitoring and Mitigation.
4. Assessing Drought …

Drought Network News (1994-2001)
In Raipur district, the onset of the monsoon occurred in the 25th standard meteorological week (June 18–24). But after the onset of monsoonal rains, there was a lull in the monsoon for about 2 consecutive weeks. In the 28th week (July 9–15), the district received 77.6 mm of rainfall. This was equal to the normal value for that week. In the following (29th) week, the district received 96.8 mm rainfall, 38.9% more than the normal rainfall for that week.
Thus, the rice, soybean, and other crops sown with the onset of the monsoon in the 25th week suffered from acute …

Famine And Drought: The Question Of Food Security In Zimbabwe, Joshua Chigodora
Drought Network News (1994-2001)
From the time that the London Missionary Society first took Zimbabwean rainfall records at Hope Fountain in 1888, the worst droughts on record are the consecutive dry spells from 1911 to 1914, the 1946–47 drought, the 1960 drought, and the 1972–73 rainy season, which was the driest period of colonial Zimbabwe. The country also had serious food shortages in 1903, 1916, 1922, 1933, and 1942. Although the people of precolonial Zimbabwe experienced recurrent droughts, they generally had well-developed coping mechanisms that prevented high death tolls (Iliffe, 1990).

Considerable variation in moisture conditions, on both a spatial and temporal basis, occurred in the contiguous United States during 1996. A tenth or more of the country experienced severe to extreme short-term (i.e., monthly) precipitation deficits during nearly half of the months (Figure 1), but in many months there were also large areas of excessive precipitation, which resulted in overall national conditions averaging near normal to wetter than normal (again, see Figure 1). From a national perspective, long-term drought peaked at mid-year (Figure 2), when severe drought plagued the South and Southwest.
Climatic Uncertainties And Recent Experiences In Medium-Range Weather Forecasting Over Kashmir, Badrul Hasan, Rehana Habib Kanth
Climatic Uncertainties And Recent Experiences In Medium-Range Weather Forecasting Over Kashmir, Badrul Hasan, Rehana Habib Kanth
Drought Network News (1994-2001)
Successful crop management and production require a precise and thorough understanding of agroclimatic conditions of a region. A crop experiences a range of weather conditions during its vegetative and reproductive phases. Although the agronomic inputs at optimum levels decide satisfactory and stable crop yields, the range of weather and climatic optimum prevalent at important crop stages determine the ultimate yields. Thus, even with all inputs at our disposal, we cannot afford to ignore the environmental conditions experienced by the crop. Systematic and continuous measurements of weather elements provide basic data input for tuning any type of computer-based forecasting system. This …

Western Rajasthan constitutes 62% of the 0.32 million km2 that make up the hot Indian arid region (Figure 1). The average annual rainfall of the area varies from less than 100 mm (coefficient of variation [CV] = 70%) in the western parts to just above 500 mm (CV = 40%) in the eastern parts of arid Rajasthan. During July and August, the eastern parts of the arid region have an assured crop growing period of 12–15 weeks, whereas the western parts mostly depend on the vagaries of the southwest monsoon. The annual potential evapotranspiration rates are 3–8 times higher …

In the October issue of Drought Network News, I briefly discussed two policy initiatives that developed in response to the severe and widespread drought that affected the Southwest and southern Great Plains states in the United States during 1996. The first of these activities, a multistate workshop (and its subsequent report), was coordinated by the Federal Emergency Management Agency. This report was submitted to President Clinton in late August; it contained a series of recommendations that focused on short- and long-term issues. The second initiative, under the leadership of the Western Governors’ Association (WGA), was not available in final …
