Modelling Changes in Climate and Land Use in 2100. Importance of climate for business and policy.

The availability of climate change models and derived values has produced quantifiable indices for temperatures, precipitation, soil moisture and others, with different scenarios of evolution, These have been developed and made available by the public sector and academia, and now largely been validated within the past 20 years.

These data can be used to calculate the impact of the changes on the future of key resources, such as agricultural land and productivity, in an effort led both by the public and private sector, as these expected changes are of interest to policymakers, business managers, investors as well as to the public at large in sectors ranging from agriculture to energy and urban development and many others.

This paper analyses the potential impact of climate change on the size and productivity of agricultural land until the year 2100 in different regions of the world. It further includes an estimate of world population development and the likely impact on the food demand and supply in different regions of the world.

Based on these predictions, the paper addresses the most likely policy and business implications. and the need for the public and private sectors to cooperate in mastering the expected challenges.

It concludes by showing the areas in which meteorology has a significant or even essential influence on the decisions to be taken and demonstrates some simple applications to access climate data which can be used for estimating further climate evolution on a local level and quantifying the impact of this evolution on various policy and business decisions.
