Senegal

Ttere are two important options that farmers producers in Senegal employ, and these are the use of food production-related forecasting and early warning systems and the invention and diffusion of sustainable technology compatible with agricultural conditions. In Uganda, the farmers' coping toolkit for agriculture includes use of farmers' traditional knowledge of micro-environment diversification, intensification of vegetation on farmlands in order to reduce soil erosion and sedimentation rates...

Raised bed cropping system

In most of the developing countries where irrigated cropping is widely practiced, a number of common problems emerge such as low yields, salinity of the soil, deteriorating soil structures, ground water depletion and water scarcity. In the rice- wheat belts of Pakistan and India, one innovative approach to address these issues is raised cropping beds (Page 2005). Beds are formed with narrow trenches between the beds serving as access and left in place for up to five years. Crops are planted...

Seasonal weather forecasts for crop yield modeling in Europe

Seasonal weather forecast for crop yield modeling in Europe is one of the applications of weather risk management, tte variability of weather at different time scales, such as daily, monthly, seasonal and beyond, is one of the factors that determine the growth of field-grown crops, tte key weather parameters for crop prediction are rainfall, temperature and solar radiation, secondary parameters being humidity and wind speed. Crop predictions require forecasts of these variables several weeks or...

Informal risk management mechanisms

Tte production strategy selected becomes an important means of mitigating the risk of crop failure. Traditional cropping systems in many places rely on crop and plot diversification. Crop diversification and intercropping systems signify common strategies of reducing the risk of crop failure due to adverse weather events, crop pests, or insect attacks. Morduch (1995) presents evidence that households whose consumption levels are close to subsistence (and which are therefore highly vulnerable to...

Farmers coping strategies

Farmers in Africa have been subjected to persistent unfavorable climatic conditions. tte level of assets and wealth determine how much adjustments one can make to sustain agricultural production. In Zambia, a recent World Bank Survey reported an increase in poverty levels in the rural areas from 70 in 1994 to 90 in 1995 (Balat and Porto 2005). ttese statistics reinforce the fact that farmers have to find coping strategies to survive. At the institutional level, ineffective extension and...

Options for future adaptation strategies

Strategies to adapt to climate change should not be seen as individual remedies since agriculture will compete for water allocation with other sectors affected by climate change. Short term adjustments should aim at optimising production without introducing major system changes, but for long-term adaptations heavier structural changes will take place to alleviate the adverse effects of climate change. Suggested adjustments include changes in planting strategies and the use of more appropriate...

Operational Agrometeorological Services to Cope with Risks and Uncertainties of Natural Disasters

National Weather Service (NWS) was created in 1870 and was officially transferred to the Department of Agriculture (USDA) in 1891 and then to the Department of Commerce (DOC) on June 30,1940. As early as 1941, operational agrometeorological services were provided for orchardists under DOC and USDA weather, climate, and agricultural activities, tte farmers were advised on conditions suitable for spray on fruit trees. Pioneering research at USDA resulted in the publication of Atlas of...

The basis of drought contingency planning

Drought planning and water crisis management needs to be proactive, is is largely because overall policy, legislation, and specific mitigation strategies should be in place before a drought or water crisis affects the use of the country's water resources. Bruins (2001) provided the basic elements involved in the development of proactive drought contingency planning and their respective relationships, ese basic elements (Figure 24.1) involve drought risk analysis, drought impact assessment, and...

Drought Types and Vulnerability

All types of drought originate from a deficiency of precipitation (Wilhite and Glantz 1985). When this deficiency spans an extended period of time (i.e., meteorological drought), its existence is defined initially in terms of these natural characteristics. However, the other common drought types (i.e., agricultural, hydro-logical, and socioeconomic) place greater emphasis on human or social aspects of drought, highlighting the interaction or interplay between the natural characteristics of the...

Optimization offarm technologies and water resources

It is well known that on a global scale water is probably the most limited resource for agricultural production and directly sensitive to climate variability. Water resources can therefore vary strongly from year to year and within a single year. Extreme precipitation events and floods can be as devastating as droughts (Rosenzweig et al. 2002 Chang 2002), and these extremes could increase under climate change, depending on the region. Extreme precipitation can further lead to nitrogen leaching...
