Drought is one of the most threatened natural vulnerabilities that are initiated by reason of scarcity of rain in a specific region. By comparing with all other natural hazards, it is very tough to discover since it develops slowly and have massive effect on the society and environment. Hence, in many countries satellite based drought indications have been recommended for early identification. ...

The degree to which biodiversity may promote the stability of grasslands in the light of climatic variability, such as prolonged summer drought, has attracted considerable interest. Studies so far yielded inconsistent results and in addition, the effect of different grassland management practices on their response to drought remains an open question. We experimentally combined the manipulation ...

Although drought is a normal, recurring feature of climate, little progress has been made in drought management in most parts of the world. The progress in drought planning that has been achieved in some countries and regions can be useful for other drought-prone regions. In this paper, a drought planning process, originally developed in 1991 for state-level government in the United States, is ...

Drought management depends on indicators to detect drought conditions, and triggers to activate drought responses. But determining those indicators and triggers presents challenges. Indicators often lack spatial and temporal transferability, comparability among scales, and relevance to critical drought impacts. Triggers often lack statistical integrity, consistency among drought categories, and...

Drought affects virtually all regions of the world and results in significant economic, social and environmental impacts. The Federal Emergency Management Agency estimates annual drought-related losses in the United States at $6-8 billion, which is more than any other natural hazard. Congress enacted the Agricultural Risk Protection Act of 2000 to encourage the United States Department of Agric...

The development and implementation of a drought policy is intended to alter a nation’s approach to drought management. A national drought policy should establish a clear set of principles or operating guidelines to govern the management of drought and its impacts. The policy should be consistent and equitable for all regions, population groups, and economic sectors and consistent with the goals...

Drought is a frequent challenge to beef producers, and many operations would benefit from developing a better drought management plan. Producers should be constantly aware of their pasture conditions, stored forage supplies, animal feed demand, and long-term weather forecasts. The recent widespread drought across the Southern U.S. has led to large harvested forage shortages, depressed local cat...

This paper explores the value of triggers and declarations in the management of drought, bringing together two disciplinary perspectives, those of the public policy scholar and the climate scientist. These two perspectives highlight the complexity of the development and use of triggers in drought risk management by drawing on the experience of the United States, which has the most sophisticated...
