*** The devastating floods in Pakistan this year destroyed the homes of more than 7 million people including more than 70,000 pregnant women. NPR's Diaa Hadid has this report from an encampment in southern Pakistan.

DIAA HADID, BYLINE: Neha Mankani peeks into tarpaulin tents pitched in tidy rows, flapping in a hot breeze that whips up the dust.

NEHA MANKANI: I'm looking for pregnant women. I'm trying to mobilize them so they can come to my makeshift clinic.

HADID: Mankani's a midwife who leads the Mama Baby fund. It's a small Pakistani charity running pop-up clinics in flood-affected areas...

HADID: ...Like this encampment for families made homeless in the floods. It's pitched between cotton fields near a village called Sheikh Daro.

HADID: Within minutes on the day we visit, there's a crowd waiting outside her makeshift clinic.

HADID: Mankani and her team beckon the women in one at a time.

HADID: In one corner, there's a daybed. In another, volunteers rip open boxes packed with supplements and pills for the women and children.

HADID: A pregnant woman walks in with a wailing toddler.

UNIDENTIFIED PERSON #1: (Non-English language spoken).

HADID: Mankani asks her to lie down, raises her thin cotton shirt, feels her belly, listens for a heartbeat.

HADID: Baby's fine, but the woman needs support for iron deficiency.

UNIDENTIFIED PERSON #1: (Non-English language spoken).

HADID: Mankani turns her attention to the crying toddler. He's not getting enough food. He's got diarrhea, which is making his malnutrition worse. And there's another complication.

MANKANI: Sounds like the baby had seizures at some point, yeah.

HADID: The mother doesn't know why her boy's having seizures. Is it the heat? Mankani says he needs a doctor, not a midwife. She gives him nutritional supplements for now. Maybe that will help.

UNIDENTIFIED PERSON #2: (Non-English language spoken).

HADID: A rhythm emerges - a noisy crowd outside, a woman comes in, they chat.

HADID: Mankani and another midwife, Jahan Zuberi, check for fetal heartbeat.

HADID: But it's the mothers and babies who need help. The midwives dole out vitamins, iron supplements, anti-nausea pills, food supplements, infant formula. Then, 30-year-old Shehzadi walks in - thin, with a little belly, five months along. She's worried about where she'll give birth.

MANKANI: (Non-English language spoken). So she's saying she hopes that she'd be back in her village before this one is born so that she can give birth at a facility. If not, she says, I'll have to give birth in a camp.

HADID: But Shehzadi is probably going to give birth in this camp because there's no money to rebuild her home. Mankani knows this, and she's prepared delivery kits for the women. She gives one to Shehzadi. It's got a sterile, plastic sheet to give birth on, a razor to cut the umbilical cord, nappies for baby, medicine to prevent hemorrhage.

HADID: Then, there's an interruption. It's nearly time for prayers. A man tells Mankani that her team have to move. The encampment's religious leader wants to pray, and he won't pray in any other tent.

MANKANI: We're going to have to move. How will we move all our stuff?

HADID: Mankani's team quickly find another empty tent. The crowd of waiting women follow them. But they've been waiting for hours, and it's only getting hotter - around 110 degrees now.

HADID: One woman holds up a crying, thin-boned baby girl to the new tent's fly screen window.

UNIDENTIFIED PERSON #3: (Non-English language spoken).

HADID: She's trying to get Mankani's attention.

MANKANI: Baby's mother is dead.

HADID: The baby's mother is dead?

The baby's mother died. This woman is her aunt, and she says the girl needs baby formula urgently.

HADID: Next, a little girl tries to get the midwives' attention.

MANKANI: (Non-English language spoken). Hey, that's not a pregnant woman.

HADID: Mankani says, that's not a pregnant woman.

HADID: The little girl holds up a baby for the midwives to see. He's so fragile he looks like a doll. Mankani quickly lets the girl in.

DIAA HADID AND NEHA MANKANI: Zaman.

HADID: Are you his sister?

Ruksana doesn't know her brother's age. She says he was born in the winter. Mankani opens his mouth to check if he's got teeth. She guesses he's about 1.5, maybe 2. But he's so small it seems hard to believe. Mankani rummages through boxes, gives Ruksana a bag of vitamins and powdered milk. Ruksana touches Mankani's feet to show gratitude.

MANKANI: OK. I think one more?

HADID: Five hours into the clinic, it's time for a break. Mankani sits down on a daybed near a solar-powered fan. For seven years, she's run midwife clinics in some of Pakistan's poorest and most remote areas like communities who live on islands in the Arabian Sea.

MANKANI: It's very humid. It's very hard - but nothing like this.

MANKANI: Yes, this is terrible.

HADID: She says here it's the heat, the desperate need of mothers and children who've long been poor, malnourished, and have now lost everything to these floods. And she knows she's only treating a fraction of the women and children who need her care. But she makes peace knowing she's doing all that she can.

MANKANI: So I just have this philosophy that all the women I see myself I know are getting respectful care. That's part of why. And we're a little crazy.

HADID: Outside, there are still dozens of women waiting.

(SOUNDBITE OF CAR ENGINE REVVING)

HADID: Back in town later that evening, Mankani messages me to say her team saw 80 women that day. She'll try to get some sleep. And the next day, she'll do it all over again. Diaa Hadid, NPR News, Sheikh Daro. ** Transcript provided by NPR, Copyright NPR.
