Agriculture

Globally, the agricultural sector consumes about 70% of the planet’s accessible freshwater. Because water is vital for the success of agriculture, proper water management techniques are necessary to meet food and fiber material demands around the world. Resources available here pay special attention to efficient irrigation and sustainable agriculture techniques.

Needs and Requirements for Irrigation, Comayagua and Vicinity, Honduras

Published: 
June 1, 1972
U.S. Agency for International Development
The valley areas in the vicinity of Comayagua and Siuatepeque offer considerable potential for agricultural development. Irrigation facilities have been constructed capable of delivering irrigation water to areas for more extensive than those currently irrigated. An analysis is made of the adequacy...Read more

Irrigation Projects in Guatemala, Observations and Recommendations

Published: 
May 1, 1972
U.S. Agency for International Development
This study is a result of an official request from the Guatemalan Government through USAID/Guatemala and AID/Washington to Utah State University for Technical Assistance in Drainage and Irrigation. The following plan of work was suggested: (A) Evaluate actual drainage and salinization problem in...Read more

Development of Tubewell Irrigation in Bangladesh: An Analysis of Alternatives

Published: 
February 1, 1972
U.S. Agency for International Development
Facilities for irrigation would permit substantial increases of agricultural production in Bangladesh. Only with irrigation as a boro crop in the six-month dry season possible. With its continual sunshine and the absence of recurring floods and storms that damage crops in other seasons, this period...Read more

Economic Aspects of Irrigation from Ground Water

Published: 
January 1, 1972
U.S. Agency for International Development
Typical examples of economic analysis of ground water development in Brazil are discussed, citing specific data for Bolivian conditions with conversion to Cruzeiro values, but without a detailed knowledge of commodity prices and costs in Brazil. Use of ground water can produce both irrigation and...Read more

Estimation of Irrigation Requirement for Venezuela

Published: 
January 1, 1972
U.S. Agency for International Development
Christiansen's formula was used to compute evaporation and potential evapotranspiration using 1013 months of data from 19 stations in Venezuela. Thirteen probability levels of precipitation were determined for each station. Potential irrigation requirements for 16 stations were computed based...Read more

Irrigation Requirements in Latin American Countries

Published: 
January 1, 1972
U.S. Agency for International Development
A study on irrigation requirements in Latin American Countries. With increasing needs for the developments of their natural resources, many Latin American countries are placing increased emphasis upon irrigation and the evaluation of the availability of moisture requirements for agricultural...Read more

Irrigation Requirements for Turf

Published: 
January 1, 1972
U.S. Agency for International Development
There is much over irrigation of turf. Some is unavoidable but significant savings of water can be had from a better understanding of the principles of scheduling irrigation. Irrigation scheduling is greatly facilitated by uniformity of soil depth and moisture storage capacity. This paper describes...Read more

Planning Sediment Distribution in Surface Irrigation Systems

Published: 
November 1, 1971
U.S. Agency for International DevelopmentColorado State University
This report deals with planning sediment load distribution in surface irrigation systems. The object is to route water and sediment through an irrigation canal network so that sediment discharge equilibrium is achieved by diverting the sediment inflow with the farm supplies. A computer simulated...Read more

Sub-Irrigation in the Zapotitan Project

Published: 
October 1, 1971
U.S. Agency for International Development
Studies were made to determine the feasibility of Sub-Irrigation in the lower portions of the Zapotitan Valley. The report suggests sub-irrigation as a possibility for some of the areas within the valley.Read more

Maximum Water Delivery in Irrigation

Published: 
August 1, 1971
U.S. Agency for International DevelopmentColorado State University
In order to increase the water delivery efficiency of an existing irrigation system, it is proposed that modern mathematical optimization techniques be applied to the management of irrigation water delivery. A deterministic mathematical model is developed to simulate the events that occur in...Read more
