The study examines the consequences of alternative public responses to drought shocks. It does so by drawing on household data from resettlement areas of rural Zimbabwe over the period 1992/93 to 1995/96 and the estimation of four behavioural relations: the determinants of crop income; the determinants of investment in livestock; the determinants of investment in agricultural capital stock; and...

drought is a natural disaster. because a significant impact on the agricultural and economy sector, it affects the lives of local residents. with using of the remote sensing, drought can be studied through its effects on plants and agriculture resulting in more accurate and effective results found for modeling drought. in this study, the efficiency of agricultural drought indicators for estimat...

Drought stress decreases crop growth, yield, and can further exacerbate pre-harvest aflatoxin contamination. Tolerance and adaptation to drought stress is an important trait of agricultural crops like maize. However, maize genotypes with contrasting drought tolerances have been shown to possess both common and genotype-specific adaptations to cope with drought stress. In this research, the phys...

Drought stress leaves deleterious effects on growth of maize plant while potassium plays an important role in reducing such deleterious effects. To study the role of potassium on maize plant grown under drought stress an experiment was conducted at Postgraduate Agricultural Research Station, Faisalabad, Pakistan. Maize hybrids 32-F-10 (drought tolerant) and YH-1898 (drought sensitive) were grow...

Drought stress is a major factor that contributes to disease susceptibility and yield loss in agricultural crops. To identify drought responsive proteins and explore metabolic pathways involved in maize tolerance to drought stress, two maize lines (B73 and Lo964) with contrasting drought sensitivity were examined. The treatments of drought and well water were applied at 14 days after pollinatio...

in this research standardized precipitation index (spi) in a period of 22 years(1990 to 2011) was used for zoning of climatic and agricultural drought in south khorasanprovince, iran. rainfall data of six synoptic stations were collected and used for evaluationof meteorological drought. also, reports of some local offices such as natural resources,agriculture, regional water and environment dep...

This paper analyses monthly differences in drought impact on vegetation activity in a semi-arid region in the north-east of the Iberian Peninsula between 1987 and 2000. The study determines spatial differences in the effects of drought on the natural vegetation and agricultural crops by means of the joint use of vegetation indexes derived from AVHRR images, a drought index (standardized precipi...
