This paper presents an optimal control model to analyze reforestations with two different species, including commercial values, carbon sequestration and biodiversity or scenic values. We solve the model qualitatively with general functions and discuss the implications of partial or total...

Because the financial commitments to preserve biodiversity fall short of what is needed, the elements of biodiversity must be prioritised so that limited funds can be used most effectively. The key issue I address here is the weaknesses of such prioritisation mechanisms with respect to gender...

The pledges to finance biodiversity preservation make up a fraction of the identified needs. Therefore, scientists must develop tools to help prioritise the many goals of biodiversity preservation. Analysts and policy makers often use the ‘Noah’s Ark’ metaphor to imply that society must...

Since pledges to finance biodiversity preservation are a fraction of the identified needs, scientists must develop tools to help prioritize the many goals. Analysts and policy makers often describe this problem with the “Noah’s Ark” metaphor to imply that society must choose how much and...
