Place the pork chunks in the slow cooker. Add the diced onion, minced garlic, sliced carrots, and drained chickpeas.
In a small bowl, stir together the cumin, coriander, cinnamon, paprika, ginger, salt, and black pepper. Sprinkle the spice mix over the pork and vegetables.
Pour the diced tomatoes, chicken broth, and chopped apricots into the slow cooker. Drizzle the olive oil over the top and stir gently to combine everything.
Cover and cook on low for 7 to 8 hours, until the pork is very tender and pulls apart easily with a fork.
About 10 minutes before serving, bring 1 cup of water to a boil in a small saucepan. Stir in the couscous, cover, and remove from heat. Let it sit for 5 minutes, then fluff with a fork.
Spoon the couscous into bowls and top with the pork tagine. Sprinkle with chopped cilantro before serving.
