Technical efficiency among irrigated and non-irrigated olive orchards in Tunisia

Discriminating irrigated and rainfed olive orchards with thermal ASTER imagery and DART 3D simulation

This work provides a description of the research conducted to assess methods for the discrimination between irrigated and rainfed open-tree canopies using advanced spaceborne thermal emission and reflection radiometer (ASTER) satellite imagery and discrete anisotropic radiative transfer (DART) radiative transfer 3D simulation model. Summer and winter ASTER images were acquired over a study area...

Soil water regime and water concervation efficiency in a non-irrigated semi-arid environment

The use of high-resolution weighing lysimeters to improve estimates of soil evaporation in drip-irrigated olive orchards

Soil surface resistance increase quickly during the first three days after irrigation or rain event. By explicitly incorporating surface resistance in simple equations, daily total evaporation estimation of a drip-irrigated olive grove was significantly improved. This increase in soil surface resistance could explain why observed cumulative soil evaporation is higher in locations with lower irr...

Entomological studies on malaria in irrigated and non-irrigated areas of Thar desert, Rajasthan, India.

BACKGROUND & OBJECTIVES Malaria is the major health problem in western Rajasthan yet its vector fauna and transmission dynamics thereof is not understood properly. The present investigations report complete profile of qualitative and quantitative aspects of anopheline species occurring in different settings of desert ecosystem. METHODS Area with irrigation through canal for more than 20 years...

Non-Parametric Energy Use Efficiency, Energy Ratio and Specific Energy for Irrigated Wheat Crop Production

In this paper, non parametric Data Envelopment Analysis (DEA) was subjected to the energy data of wheat producers in Punjab state, India, and technical, pure technical and scale efficiencies were calculated for farms both category wise and zone wise. The main objective was to determine the strength of the correlation between non-parametric efficiencies and indices such as energy ratio and speci...
