GWP (2000): I WRM is a process which promot es t he coordinat ed development and management of wat er, land and relat ed resources, in order t o maximize t he result ant economic and social welf are in an equitable manner wit hout compromising t he sustainability of vital ecosystems.

Def inition of I WRM

  • All dif f erent uses of wat er resources are considered t oget her
  • Wat er allocat ion and management decisions t o consider t he

ef f ect s of each use on t he ot hers

  • Take overall social and economic goals as well as achievement of

sust ainabilit y int o account

  • I ncorporat e part icipat ory decision making

Economic ef f iciency Environment al & ecological sust ainabilit y Equit y

Because of t he increasing scarcit y of wat er and f inancial resources, t he f init e and vulnerable nat ure of wat er as a resource, and t he increasing demands upon it , wat er must be used wit h maximum possible ef f iciency; The basic right f or all people t o have access t o wat er of adequat e quant it y and qualit y f or t he sust enance of human wellbeing must be universally recognized; The present use of t he resource should be managed in a way t hat does not undermine t he lif e-support syst em t hereby compromising use by f ut ure generat ions of t he same resource. (1) Fresh wat er is a f init e and vulnerable resource, essent ial t o sust ain lif e, development and t he environment .

Water Management Principles

(2) Wat er dev. & management should be based

  • n a part icipat ory

approach, involving users, planners and policymakers at all levels. (3) Women play a cent ral part in t he provision, management and saf eguarding of wat er (4) Wat er has an economic value in all it s compet ing uses and should be recognised as an economic good. “Wat er has a value as an economic good as well as a social good”

29.9% of the Earth fresh water re-sources and 99% of the blue water resources. However, only groundwater storage that exists in connected pores/ openings/ is accessible for use. GW is less susceptible to contamination than surface water

  • quite often requires little or no treatment to be used as drinking water.

Groundwater usually reacts more slowly than surface water; processes usually take longer and recharge and remediation take therefore much more time.

Percentage of land in each of the 64 districts (broken gray lines) in Bangladesh irrigated with groundwater in 2003 (BADC,2003) [Total numbers of shallow and deep tubewells operated in each district in 2003are also shown. Low-permeable extensive surface geological units are shown in the background] (Source: Shamsudduha et al., 2009)

THE ENABLING ENVIRONMENT

  • 1. Policies – setting goals for water use, protection and conservation.
  • 2. Legislative framework – the rules to enforce to achieve policies and goals.
  • 3. Financing and incentive structures – allocating financial resources to meet water

needs. INSTITUTIONAL ROLES

  • 4. Creating an organizational framework – forms and functions.
  • 5. Institutional capacity building – developing human resources.

MANAGEMENT INSTRUMENTS

  • 6. Water resources assessment – understanding resources and needs.
  • 7. Plans for IWRM – combining development options, resource use and human

interaction.

  • 8. Demand management – using water more efficiently.
  • 9. Social change instruments – encouraging a water-oriented civil society.
  • 10. Conflict resolution – managing disputes, ensuring sharing of water.
  • 11. Regulatory instruments – allocation and water use limits.
  • 12. Economic instruments – using value and prices for efficiency and equity.
  • 13. Information management and exchange– improving knowledge for better water

Goals for the enabling environment

60

 Establishing government as the “owner” of all water resources  Setting out effective water allocation mechanisms including decision support for prioritisation  Setting out mechanisms for pollution management in harmony with the environmental laws and regulations  Providing legal basis for institutional reform  Regulating conditions in case of water excessive lowering and pollution emergencies  Making provision for cost recovery, charges, incentives and financing arrangements to assist sustainability  Setting out provisions for enforcement and for sanctions in cases of non-compliance

Goals for the institutional framework

61

  • Separate water resources management functions from

service delivery functions

  • Manage surface water resources within the boundaries of a

catchment, not within administrative boundaries,

  • Decentralising regulatory and service functions to the lowest

appropriate level

  • Promote stakeholder involvement and public participation in

planning and management decisions

  • To facilitate, regulate and encourage private sector potential

contributions in financing and delivery of services

key goals within management instruments

62

 Establish a hydrological and hydro-geological service tailored for the water resources situation and the key water resources issues  Establish a water resources knowledge base based on monitoring and water resources assessments, supplemented by modelling if necessary and make available as part of public awareness raising  Establish a water allocation mechanism, a surface water, groundwater abstraction and wastewater discharge permit system and associated databases  Establish policy and planning capabilities and develop skills in risk assessment, environmental, social and economic assessments  Establish competencies in demand management and in use of prices and value for efficiency in use and equity in access  Establish human resources development and capacity building tailored to the water resources and institutional issues
