All of the following are activities of the sustenance and strengthening phase EXCEPT:

In the sustenance and strengthening phase of community health initiatives, activities are primarily focused on consolidating the efforts made during earlier phases and ensuring the community can continue to support its health program effectively. This phase emphasizes empowering community members, establishing governance structures, and enhancing skills through training.

Training community members is a vital activity that helps people develop the necessary knowledge and skills to sustain health programs over time. The formation of by-laws is crucial for establishing the framework and rules that govern the community organization's operations, providing a clear structure for decision-making. The election of officers is an essential step in establishing leadership within the community organization, which is vital for ongoing management and motivation of community health initiatives.

Conducting baseline surveys, while critical in the initial data-gathering phase of community health programs, is not typically categorized as part of the sustenance and strengthening phase. Baseline surveys are often conducted earlier to assess the needs of the community and inform the design of interventions, rather than to sustain or strengthen ongoing activities. Thus, this activity does not align with the objectives and focus of the sustenance and strengthening phase.
