Pakistan-Iran border in the context of "Balochistan, Pakistan"

Balochistan (/bəˈlɒtʃɪstɑːn, bəˌlɒtʃɪˈstɑːn, -stæn/; Balochi: بلۏچستان, romanised: Balòcestàn, Balochi pronunciation: [baˈloːt͡ʃest̪ɑːn]; Urdu: بلوچستان, romanised: Balocistān, Urdu pronunciation: [bəloːt͡ʃɪst̪ɑːn] ) is a province of Pakistan. Located in the southwestern region of the country, Balochistan is the largest province of Pakistan by land area but is the least populated one. It is bordered by the Pakistani provinces of Khyber Pakhtunkhwa to the north-east, Punjab to the east, and Sindh to the southeast; shares international borders with Iran to the west and Afghanistan to the north; and is bound by the Arabian Sea to the south. Balochistan is an extensive plateau of rough terrain divided into basins by ranges of sufficient height and ruggedness. It has a large deep-sea port, the Port of Gwadar, lying in the Arabian Sea.

Although it constitutes approximately 44% of Pakistan's land area, only 5% of it is arable, and it is noted for an extremely dry desert climate. Despite this, agriculture and livestock make up about 47% of Balochistan's economy.
