RESUMO

Drought is an important global hazard, challenging the sustainable agriculture and food security of nations. Measuring agricultural drought vulnerability is a prerequisite for targeting interventions to improve and sustain the agricultural performance of both irrigated and rain-fed agriculture. In this study, crop-generic agricultural drought vulnerability status is empirically measured through a composite index approach. The study area is Haryana state, India, a prime agriculture state of the country, characterised with low rainfall, high irrigation support and stable cropping pattern. By analysing the multiyear rainfall and crop condition data of kharif crop season (June-October) derived from satellite data and soil water holding capacity and groundwater quality, nine contributing indicators were generated for 120 blocks (sub-district administrative units). Composite indices for exposure, sensitivity and adaptive capacity components were generated after assigning variance-based weightages to the respective input indicators. Agricultural Drought Vulnerability Index (ADVI) was developed through a linear combination of the three component indices. ADVI-based vulnerability categorisation revealed that 51 blocks are with vulnerable to very highly vulnerable status. These blocks are located in the southern and western parts of the state, where groundwater quality is saline and water holding capacity of soils is less. The ADVI map has effectively captured the spatial pattern of agricultural drought vulnerability in the state. Districts with large number of vulnerable blocks showed considerably larger variability of de-trended crop yields. Correlation analysis reveals that crop condition variability, groundwater quality and soil factors are closely associated with ADVI. The vulnerability index is useful to prioritise the blocks for implementation of long-term drought management plans. There is scope for improving the methodology by adding/fine-tuning the indicators and by optimising the weights.

RESUMO

BACKGROUND: Unsafe abortion is a major cause of mortality among women in India accounting for 12% of all maternal deaths. In developing countries, annually, up to 200,000 women die of complications after illegal abortion. Medical abortion is potentially a simple and a safe method for use in developing countries. We conducted a prospective controlled trial to compare the efficacy of low-lose mifepristone and methotrexate for medical abortion. OBJECTIVE: To find out the efficacy of low-dose mifepristone and methotrexate for inducing abortion. METHOD: In this prospective clinical study, 100 women opted for a medical method of abortion. Out of these, 50 patients were given 50 mg/m2 of methotrexate intramuscularly followed by 800 micro gm of intravaginal misoprostol, and 50 patients were given 200 mg of mifepristone orally followed by 800 micro gm of intravaginal misoprostol. MAIN OUTCOME MEASURES: Complete abortion was the principal outcome measure. Secondary outcome measures were side effects and acceptability data. RESULTS: The rate of expulsion by first week after initiation of treatment was 58% in methotrexate and 98% in mifepristone group (P <0.001). CONCLUSION: Low-dose mifepristone and intravaginal misoprostol is safe, effective, and well tolerated as compared to methotrexate and misoprostol.
