Latin American countries show a great potential for expanding their irrigated areas. Irrigation is important for strengthening local and regional economy and for enhancing food security. The present paper aimed at providing a brief review on key aspects of irrigation management in Latin America. Poor irrigation management can have great impact on crop(More)
Irrigation systems should be a relevant agent to give solutions to the increasing demand of food, and to the development, sustainability and productivity of the agricultural sector. The design, managing, and operation of irrigation systems are crucial factors to achieve an efficient use of the water resources and the success in the production of crops and(More)
The response of kiwi plants (Actinidia deliciosa) to different levels of water application under drip and microjet irrigation methods was studied over a period of 3 years, to determine water-production relationships. Fruit production increases as larger volumes of water are applied up to a level equivalent to 100% of pan evaporation. In addition, water(More)
Chile contains some of the driest areas in the world, yet human activities in these areas require large volumes of water, the result is regions experiencing high water scarcity leading to environmental degradation, conflicts and reduced industrial productivity. The aim of this paper was to quantify the water scarcity in the central and northern regions by(More)
A methodology was developed using a Geographic Information System (GIS) to select, design, install and manage an irrigation system for a farm. GIS was used to develop different thematic layers, each consisting of a particular attribute required for analysis of alternative irrigation system types. These layers included data such as: topography, soil texture,(More)
The effects of four irrigation regimes on fruit production and size were evaluated for three seasons in a mature ‘Hass’ avocado orchard (Persea americana Mill.). The research was conducted in Chile’s Central Valley on a clay loam soil at the surface and sandy loam from 0.3 to 0.9 m. Climate zone is sub-humid, Mediterranean-type. A completely randomized(More)
An online dynamic decision support system (DDSS) was developed, to support the farm water management in surface irrigation. The online DDSS was based on the formulation and integration of three components: a dynamic-relational data base, an administrator model, and a graphical user interface. The DDSS allows routines of actualization, edition and addition(More)
