I have family in interior Sindh. We are Punjabi but my fathers family, grandparents and uncles settled in interior Sindh in a small town called
KUNRI after partition so there is the strong connection.
About KUNRI, it is famous for one thing, CHILIES! There is a special breed, called dandi cut is produced only here and is known around the world really.
For preservation, people are really still stuck with old techniques. The crop is laid out in open dry fields after harvest so the sun dries it. Harvest time is dry and dusty part of the year in that area, the crop out is open catches dust and that is a problem in exploring the export potential properly. Also towards the end of that drying process (which takes a few weeks) monsoon starts so it is often that some of the crop is destroyed in rains. The need is for EPB or TDAP as they call it now to step up and establish multiple de-hydration plants. They helped local farmers in Sargodah area with Kino export, establishing countless polishing and processing plants and something similar needs to be done in Kunri for chili. The de-hydration plants will make sure that all crop is as per export standards. Currently, there is one private plant running but we have around 100000 acres of chili farms in that area, one plant wont cut it!
People are taking small steps however to improve the standards. For example, since a few years, an NGO provided the farmers with sheets that they are required to put on the floor before the put the crop on it to dry. That is helping with reducing the dust it collected. Similarly one person i know have set up a small unit near Islamabad, he buy truck load of chili, process it in his unit and is exporting. However non of this is nearly enough. If the gov. can help establish some processing plants, this easily is a multi million dollar export.
