CHAPTER 4 FRAMEWORK FOR BASIN PLANNING 59
CHAPTER 4 PLANNING FRAMEWORK FOR BASIN PLANNING
4.1 Overall framework for basin planning
This chapter sets out the overall framework for basin planning: the relationship between basin planning and the many other planning exercises undertaken by government. Modern strategic basin plans need to address increasingly complex water challenges. Basin plans need to recognize and enable national water policies, and at the same time inform local and regional plans and policies. Furthermore, basin planning takes place in the context of a range of broader socio-economic and environmental planning processes.
Basin plans therefore need to consider both:
▶ Horizontal alignment, between the basin plan and plans from outside the water sector such as economic, spatial and environmental plans. These plans are likely to be at a range of scales, from national development and environmental laws and planning, through regional to local-scale plans. Typically, the geographical boundaries of the basin plan and these broader plans will not be aligned.
▶ Vertical alignment, between the basin plan and other national and local plans in the water sector.
This concept of horizontal and vertical alignment is illustrated in Figure 14.

There has been increasing recognition in recent years that decisions that affect water resources and how they are used are not made by water managers alone: there are a range of important socio-economic decisions which get made outside of the ‘water box’ that affect water (see Figure 15). It is critical that basin planners engage with those decision-makers and recognize the way different policies, processes and actions are likely to affect the water sector. This can include understanding how policies, the allocation of resources, and political and
