Valuation of Land: Theory and Application
The valuation of land for assessment purposes is always a challenging and difficult process. The issue of highest and best use of the land as if vacant and as if improved will be discussed.

Practical examples of the valuation of a typical parcel of land will be included.


Farm Land Values in a Changing World
Farmland values are rising amidst urban expansion, environmental degradation, and shifting social norms. Cities grew large due to fertile soils, favourable climates, and natural harbours. As urbanization intensifies, property assessors and municipalities face new challenges in valuing land and setting policy. This webinar explores how agriculture has influenced land use and property values, the complexities of valuing transitioning lands, and the impact of modern agricultural practices. We’ll present future scenarios, such as shifts in diet or climate change, and discuss the role of municipalities in land use planning and policy decisions. Gain insights into analyzing sales for farm valuations and the critical role of municipalities in sustainable land use.
