Climate adaptation may be rendered ineffective if policies are not designed in the context of other development concerns. For instance, a comprehensive strategy that seeks to improve food security in the context of climate change may include a set of coordinated measures related to agricultural extension, crop diversification, integrated water and pest management and agricultural information series. Some of these measures may have to do with climate changes and others with economic development.

Correct Option (D)

The passage explicitly states that climate adaptation policies may be ineffective if not designed within the context of other development concerns. It provides the example of food security, where a comprehensive strategy involves measures related to both climate change and economic development. This directly implies that climate adaptation initiatives must be considered alongside broader economic development options to achieve effectiveness and coherence.

Incorrect Options:

The passage does not assert that pursuing climate adaptation is inherently difficult in developing countries. It focuses on the necessity of integrating climate adaptation with broader development goals for efficacy, irrespective of the specific geographical context.

The passage uses improving food security as an illustration of a complex development issue that requires a coordinated approach when addressed in conjunction with climate change. It does not make a comparative claim regarding the relative complexity of food security versus climate adaptation itself.

While many developmental activities may have connections to climate adaptation, the passage emphasizes the integration of climate adaptation with *other* development concerns. It does not present a universal claim that every single developmental activity is directly or indirectly linked to climate adaptation.
