Spontaneously broken supersymmetry plays important roles in supergravity model buildings. Below the supersymmetry breaking scale, the effective theory is well described by nonlinear realizations of supergravity. We show two applications of nonlinearly realized supergravity: One is the effective action of anti-D3 brane in KKLT background. The KKLT model is well known as the string realization of de Sitter vacua. The anti-D3 brane plays an important role in uplifting the vacuum. We show that the world volume fields on anti-D3 brane and their couplings are described in terms of the constrained superfields (nonlinear realizations). Secondly, we show that the nonlinear realization is useful to realize non-supersymmetric models within supergravity. As an example, we show the embedding of the Horndeski model into supergravity, which describes the most general ghost-free scalar-tensor system.
