Most agricultural pests are poikilothermic species expected to respond to climate change. Currently, they are a tremendous burden because of the high losses they inflict on crops and livestock. Smallholder farmers in developing countries of Africa are likely to suffer more under these changes than farmers in the developed world because more severe climatic changes are projected in these areas. ...

Canopy characterization is essential for pesticide dosage adjustment according to vegetation volume and density. It is especially important for fresh exportable vegetables like greenhouse tomatoes. These plants are thin and tall and are planted in pairs, which makes their characterization with electronic methods difficult. Therefore, the accuracy of the terrestrial 2D LiDAR sensor is evaluated ...

Abstract High levels of crop species diversity are considered beneficial. However, increasing might be difficult because environmental constraints and the reliance on a few major crops for most food supply. Here we introduce theoretical framework hierarchical diversity, in which requirements limit potential demand agricultural products further constrain attainable diversity. We estimated global...

irrigular land use, land degradation and increasing yield per surface area unit supplicate to be inevitable optimal land utilization.so land evaluation, planning and management to be necessary to achieve a sustainabledevelopment.following this trend, microleis (mediterranean land evaluation information system)has evolved towards an agro-ecological decision support system.the goal of this study ...

Crop selection for sustainable and effective agricultural land management has to take into accounts several issues such as chemical, physical, environmental, economic social conditions. Especially after consolidation projects, crop should be investigated each which are suitable the project area benefit from contributions irrigation, roads, modified parcel boundaries surfaces. Thus, Geographical...

Leaf area index (LAI) is a key variable for modeling energy and mass exchange between the land surface and the atmosphere. Inversion of physically based radiative transfer models is the most established technique for estimating LAI from remotely sensed data. This study aims to evaluate the suitability of the PROSAIL model for LAI estimation of three typical row crops (maize, potato, and sunflow...
