Mulazim Hussain is proud of the trees he has planted.
Surrounded by neem saplings and vegetables sprouting up from scrubland in the Clifton district of Pakistan's largest city Karachi, the 61-year-old recalls a time a few years ago when the area was a giant, informal rubbish tip.
"Now there is greenery and happiness, children come in the evening to play, people come to walk," he said, speaking near a patch of trees amid a barren expanse bordered by the sea on one side and tower blocks and offices in the distance on the other.
"I have raised these plants like my children over the last four years," he added, taking a break from his labours amid a fierce summer heatwave.

Wearing a white and brown scarf around his head and a loose, cream-coloured shirt, Hussain collected dry grass from the ground and watered his cherished trees during a recent visit by Reuters reporters to the urban forest plantation project.
At the end of the day, he turned the hose on himself to cool off and clean up before heading home on his motorcycle.

It is one of dozens of state-owned and private planting initiatives in Pakistan, where forest cover lags far behind average levels across South Asia. Trees absorb carbon dioxide, emissions of which contribute to warming global temperatures.
The aim in Clifton is to counterbalance rapid urbanisation in Karachi, a sprawling port city of some 17 million people where breakneck expansion of roads and buildings means there is less and less space for trees and parkland.
Qureshi wanted to provide shade for residents seeking escape from rising temperatures - a heatwave in 2015 killed more than 400 people in the city in three days, and temperatures in the surrounding Sindh region reached record highs this year.

The trees can also attract local wildlife, mitigate urban flooding and provide new sources of food.
"The bigger the tree cover of the city the more the cooling, with a difference of up to 10 (degrees) Celsius when you are surrounded by trees," he told Reuters, adding that the project only used native species.
"As you plant ... it attracts insects, and varieties of birds start coming. Presently mongoose are roaming around in the park, and four or five varieties of chameleon.
"You give them a home, you give them food and let it happen. Nature is so beautiful."

DOES PLANTING HELP?
Overall forest cover in Pakistan, home to more than 220 million people, is around 5.4%, according to Syed Kamran Hussain, manager for the Khyber Pakhtunkhwa province at the World Wide Fund for Nature's national branch.
That compares with 24% in neighbouring India and 14.5% in Bangladesh, and the previous government announced a mass forestation programme that envisaged planting 10 billion trees between 2019 and 2023.
"Pakistan is among the top 10 most vulnerable countries affected by global warming," Hussain said. "After oceans, trees are the second largest sink of carbon."
Some climate change experts question the impact of afforestation projects - the planting of trees where there were none before - in urban settings.

The choice of species is important, because it affects the amount saplings may need to be watered - a major factor in Pakistan where water is generally scarce.
And whether to plant trees at all is not a simple question: the benefits are not always clear and significant investment is needed to nurture saplings into fully grown trees.
"What is missing from urban forestry is a holistic approach to the environment," said Usman Ashraf, a doctoral researcher in development studies at the University of Helsinki. He was not commenting specifically on the Karachi project.
