The relation between water use and pesticides – Some remarks on the influence of integrated farming practices AgEcon
Noack, Eva Maria; Bergmann, Holger.
Agriculture is the main user of the world’s water resources. Due to increasing concern on water quality and quantity, there is a growing interest to use the scarce water resources in the most efficient way to feed the growing world population. By employing a meta-analysis, this paper shows that pesticide use in combination with other improved production technologies have tripled agricultural water use efficiency (WUE) in the last 30 years. Recently, the European Union banned several active substances, among these more than 20 pesticides formerly used in crop growing. By doing so the progress in WUE has been put into question. This paper argues that a sudden reduction of pesticides by 50 % would lead to a need for more than 55 million hectares of additional...

Modelling Beef and Dairy Sectors' Productivities and their Effects on Land Use Change in Brazil Rev. Econ. Sociol. Rural
Harfuch,Leila; Nassar,André Meloni; Zambianco,Wilson Milani; Gurgel,Angelo Costa.
Abstract: This paper aims to develop new methodology for the Brazilian beef and dairy sectors incorporating different levels of productivities in the Brazilian Land Use Model (BLUM), analyzing land use dynamics. Several datasets combinations were used and supply and demand equations were re-estimated. Historical database developed in this paper shows that the livestock sector increased productivity levels per hectare (in both beef and dairy sectors), being an important land releaser for other agricultural uses. Even in frontier regions, the occupation process was followed by productivity increase. When technologies were implemented in BLUM, results show that there were significant differences on land use in 2030, reducing land for pasture compared to BLUM...
