The adjective 'förderlich' (beneficial) is closely related to the verb 'fördern' (to support/promote), which means 'unterstützen' (to support) or 'voranbringen' (to advance). Something that is 'förderlich' therefore helps to achieve a goal.

The government wants to provide stronger support for small businesses.
'Förderlich' (beneficial) is almost always used with the preposition 'für' (for) and the accusative in order to name the goal or area on which it has a positive effect.
Eine gute Arbeitsatmosphäre ist förderlich für die Produktivität.
A good working atmosphere is beneficial for productivity.
The adjective is often combined with abstract nouns that describe a process or state. Typical examples are 'förderlich für die Gesundheit' (beneficial for health), 'die Karriere' (one's career), 'die Entwicklung' (development), or 'das gegenseitige Verständnis' (mutual understanding).

'günstig' and 'förderlich' both describe something that is good for a goal. 'günstig' often means that the circumstances fit or bring an advantage. 'förderlich' says more clearly that something supports a development or makes progress possible. That is why 'förderlich' sounds somewhat more formal and fits well with topics such as learning, health, cooperation, or development. In everyday life, people more often say 'günstig' when they are simply talking about suitable conditions.
