This article offers an overview of the vicissitudes faced by Israeli agriculture during the past century. 

The aims were: Understanding how the relationship between species richness and its determinants depends on the interaction between scales at which the response and explanatory variables are measured; Quantifying the relative contributions of local, intermediate and large-scale determinants of species richness in a fragmented agro-ecosystem; Testing the hypothesis that the relative contribution of these determinants varies with the grain size at which species richness is measured.

It was asked- to what extent do predators use non-crop habitats as refuges or breeding sites in the desert agroecosystem of the northern Negev, Israel? thet investigated the use of natural desert habitat, planted trees (Eucalyptus), and a summer crop (sunflowers) by winter-wheat inhabiting spiders.

The water management policies adopted to address Israel’s chronic scarcity have not been without environmental consequences. Yet, through a trial-and-error process, a combined strategy of water transport, rainwater harvesting, and wastewater reuse and desalination, along with a variety of water conservation measures, have put the country on a more sustainable path for the future.

Our ability to improve biological control of insect pests depends on our understanding of factors that limit the reproductive success of their natural enemies in the field. Pest control by parasitoids in agricultural fields can be compromised by the availability of sugar resources. We studied sugar availability for Anagrus parasitoids that parasitize the eggs of leafhopper pests (genus Erythroneura) in vineyards in northern California.

The present study compares activity-densities and species richness of spiders in two dominant habitat types in the arid agroecosystem in the northwest Negev Desert- Intensively cultivated arable land and semi-desert.
