Heat oil in large Dutch oven over medium-high heat until shimmering. Add onion and celery and cook, stirring frequently, until translucent and starting to brown, 7 to 8 minutes. Reduce heat to medium, add garlic and ginger, and cook until fragrant, 1 minute. Stir in coriander, paprika, cumin, cinnamon, and pepper flakes and cook for 1 minute. Stir in ½ cup cilantro and ¼ cup parsley and cook for 1 minute.
Stir in broth, water, chickpeas, and lentils; increase heat to high and bring to simmer. Reduce heat to medium-low, partially cover, and gently simmer until lentils are just tender, about 20 minutes.
Stir in tomatoes and pasta and simmer, partially covered, for 7 minutes, stirring occasionally. Stir in chard and continue to cook, partially covered, until pasta is tender, about 5 minutes longer. Off heat, stir in lemon juice, remaining ¼ cup cilantro, and remaining ¼ cup parsley. Season with salt and pepper to taste. Serve, passing lemon wedges separately.
