Cholera continues to be an important cause of human infections, and outbreaks are often observed after natural disasters, such as the one following the 2010 earthquake in Haiti. Once the cholera outbreak was confirmed, rumors spread that

In engineering practice, simple methods are important for predicting runoff from watersheds particularly for flood forecasting and water balance calculations. In the present study, it is illustrated that the often-used SCS runoff curve-number approach in its most elementary form can be derived from assuming that only saturated areas contribute to direct runoff.

Direct measurement of soil erodibility, resistance offered by the soil to both detachment and transport processes, is not only costly but time consuming also. So, efforts have been made to predict it from the soil physical properties.

A laboratory investigation was conducted to evaluate Campbell soil water retention model parameters, viz., pore size distribution index, notional air entry potential and saturation moisture and to develop pedotransfer functions for the soils of Central Brahmaputra Valley Zone of Assam.

Water is a prime natural resource, a basic human need and precious natural asset. Surface runoff is the major source for all the major source for all the surface water bodies such as tanks and reservoirs. The dependable assessment of runoff is scarcely available in few selected locations. In the present study, Soil Conservation Service Curve Number (SCS-CN) method has been applied to assess the runoff for Nambiyar sub-watershed of Thamiravaruni River Basin, Tirunelveli District, Tamil Nadu.

A field experiment was conducted during 2004-2006 taking greengram-mustard-cowpea crop sequence with greengram cv. 'SML 668' in kharif, mustard cv. 'Pusa Jaikisan' in rabi and cowpea cv. 'Pusa Komal' in summer. The objective was to study the effect of conservation tillage and crop establishment practices on performance, energy saving and soil organic carbon content in the system.

Accurate and realistic estimates of carbon stock on trees are essentially required for determining their role in mitigating global warming and climate change in present scenario of enhanced atmospheric carbon dioxide (CO2) coupled with the rise in temperature. In this background, a study was conducted at National Research Centre for Agroforestry, Jhansi to assess carbon sequestration potential and its allocation in different tree-components of eight important agroforestry tree species of Bundelkhand region in Central India.

In the present investigation, impact of different tillage options on wheat yield has been evaluated for various locations of IGP region. In general, more increase in wheat yield was observed was observed in zero tillage when compared with conventional tillage.

A field experiment was conducted at the research farm of Indian Agricultural Research Institute, New Delhi during 3 wet and dry seasons of 2003-06 in rice-wheat cropping system. In this experiment different treatments comprising organic amendments such as blue green algae, vermicompost and farm yard manure applied alone or in combination were tested in organic crop production.
