Book (stand-alone)Agricultural Drainage Water Management in Arid and Semi-Arid Areas 2002
Also available in:
No results found.This publication provides planners, decision-makers and engineers with guidelines to sustain irrigated agriculture and at the same time to protect water resources from the negative impacts of agricultural drainage water disposal. On the basis of case studies from Central Asia, Egypt, India, Pakistan and the United States of America, it distinguishes four broad groups of drainage water management: water conservation, drainage water reuse, drainage water disposal and drainage water treatment. All these options have certain potential impacts on the hydrology and water quality in an area, with interactions and trade-offs occurring when more than one is applied. This publication presents a framework to help make a selection from among the various drainage water management options and to evaluate their impact and contribution towards development goals. In addition, it presents technical background and guidelines on each of the options to enable improved assessment of their impacts and to fac ilitate the preparation of drainage water management plans and designs. -

Also available in:
In 1986, within its Forestry for Community Development Programme, the FAO Forestry Department published a Forestry Paper entitled Tree Growing by Rural People. It presented various facets of the state of knowledge about tree-growing as it relates to community forestry i.e. forestry designed to benefit the rural tree growers/managers. However, although some of the most interesting future opportunities for community forestry lie in improving management of existing trees rather than in creating new resources, this document covered only partially the topic of tree and woodland management by rural people. It did not fully explore how rural people manage single trees or communal woodlands and how they manage their other resources in relation to trees and woodlands. Further effort was necessary to broaden and deepen the knowledge base on local management issues. In order to improve the success of management projects, more complete data and analysis was also needed on what knowledge rural peop le have already developed and the dynamics of their tree resource management strategies in response to changing policies, pressures and opportunities. Finally, more thorough understanding was to be developed of the results and impacts of various attempts to support rural people in the efforts to manage these resources. -
