Small-scaled subsistence farming is the key to keep our soil healthy and fertile. On the other hand the factory farming is resulting in the soil erosion and narrowing the genetic resources (biodiversity). The erosion of soil has largely occurred due to the loss of structure by continual disturbance for crop planting and harvesting. If soil is repeatedly turned over, it is exposed to oxygen and its carbon is released into the atmosphere, causing it to fail to bind as effectively. This loss of integrity impacts soil’s ability to store water, which neutralizes its role as a buffer to floods and a fruitful base for plants.
The world has lost a third of its arable land due to erosion or pollution in the past 40 years, with potentially disastrous consequences as global demand for food soars, scientists have warned.

I’m PhD in Animal Agriculture, currently working as a Technical Manager at Al Ain Farms for Livestock Production, Camel dairying, Alain, UAE. I had performed as a Professor and Dean, at the Faculty of Veterinary and Animal Sciences, Lasbela University of Agriculture, Water and Marine Sciences Pakistan (LUAWMS). I work on and write for the subjects of ‘turning camel from a beast of burden to a sustainable farm animal’, agricultural research policies, extensive livestock production systems, food security under climate change context, and sustainable use of traditional genetic resources for food and agriculture.
Iim advocating camel under the theme of CAMEL4LIFE and believe in camel potential. I’m the founder and head of the Society of Animal, Veterinary and Animal Scientists (SAVES), and Founder of the Camel Association of Pakistan. I also work as a freelance scientist working (currently member of steering committee) for Desert Net International (DNI).
I’m an ethnoecologist, ethnobotanist, Ethnovet and ethomedicie researcher and reviewer. I explore deserts and grazing lands for knowledge and understanding.
