هلال حاصلخیز (به عربی: هلال خصیب، بهمعنی: داس بارور)، نام بخش تاریخی از خاور میانه و دربرگیرندهٔ بخشهای خاوری دریای مدیترانه، میانرودان و مصر باستان میباشد. این نام نخستین بار از سوی جیمز هنری بریستد باستانشناس دانشگاه شیکاگو بر این بخش از جهان گذاردهشد.
داس بارور با رودهای نیل، دجله، فرات و رود اردن سیراب میشود. این منطقه از باختر به دریای مدیترانه، از شمال به بیابان سوریه و از دیگر سویها به شبه جزیره عربستان و خلیج فارس و دیگر بخشهای مدیترانه محدود میشود. داس بارور امروزه کشورهای مصر، اسرائیل، لبنان و نیز کرانه باختری رود اردن و نوار غزه و بخشهایی از اردن، سوریه، عراق، جنوب شرقی ترکیه، غرب و جنوب غربی ایران را دربرمیگیرد. جمعیت داس بارور را امروزه نزدیک به ۱۲۰ میلیون یا دست کم یکچهارم جمعیت کل خاورمیانه تخمین میزنند.

The Fertile Crescent is a crescent-shaped region in the Middle East, spanning modern-day Iraq, Israel, Palestine, Syria, Lebanon, Egypt, and Jordan as well as the southeastern fringe of Turkey and the western fringes of Iran. Some authors also include Cyprus.
The region has been called the "cradle of civilization", because it is where settled farming first began to emerge as people started the process of clearance and modification of natural vegetation in order to grow newly domesticated plants as crops. Early human civilizations such as Sumer flourished as a result. Technological advances in the region include the development of writing, glass, the wheel, agriculture, and the use of irrigation.
The term "Fertile Crescent" was popularized by archaeologist James Henry Breasted in Outlines of European History (1914) and Ancient Times, A History of the Early World (1916). Breasted wrote:
In current usage, the Fertile Crescent includes Israel, Palestine, Iraq, Syria, Lebanon, Egypt, and Jordan, as well as the surrounding portions of Turkey and Iran. Water sources include the Jordan River. The inner boundary is delimited by the dry climate of the Syrian Desert to the south. Around the outer boundary are the Anatolian and Armenian highlands to the north, the Sahara Desert to the west and the Iranian Plateau to the east.
Biodiversity and climate
As crucial as rivers and marshlands were to the rise of civilization in the Fertile Crescent, they were not the only factor. The area is geographically important as the "bridge" between Africa and Eurasia, which has allowed it to retain a greater amount of biodiversity than either Europe or North Africa, where climate changes during the Ice Age led to repeated extinction events when ecosystems became squeezed against the waters of the Mediterranean Sea. The Saharan pump theory posits that this Middle Eastern land bridge was extremely important to the modern distribution of Old World flora and fauna, including the spread of humanity.
The area has borne the brunt of the tectonic divergence between the African and Arabian plates and the converging Arabian and Eurasian plates, which has made the region a very diverse zone of high snow-covered mountains.
The Fertile Crescent had many diverse climates, and major climatic changes encouraged the evolution of many "r" type annual plants, which produce more edible seeds than "K" type perennial plants. The region's dramatic variety in elevation gave rise to many species of edible plants for early experiments in cultivation. Most importantly, the Fertile Crescent was home to the eight Neolithic founder crops important in early agriculture (i.e., wild progenitors to emmer wheat, einkorn, barley, flax, chick pea, pea, lentil, bitter vetch), and four of the five most important species of domesticated animals—cows, goats, sheep, and pigs; the fifth species, the horse, lived nearby. The Fertile Crescent flora comprises a high percentage of plants that can self-pollinate, but may also be cross-pollinated. These plants, called "selfers", were one of the geographical advantages of the area because they did not depend on other plants for reproduction.
As well as possessing many sites with the skeletal and cultural remains of both pre-modern and early modern humans (e.g., at Tabun and Es Skhul caves in Israel), later Pleistocene hunter-gatherers, and Epipalaeolithic semi-sedentary hunter-gatherers (the Natufians); the Fertile Crescent is most famous for its sites related to the origins of agriculture. The western zone around the Jordan and upper Euphrates rivers gave rise to the first known Neolithic farming settlements (referred to as Pre-Pottery Neolithic A (PPNA)), which date to around 9,000 BCE and includes very ancient sites such as Göbekli Tepe and Jericho (Tell es-Sultan).
This region, alongside Mesopotamia (which lies to the east of the Fertile Crescent, between the rivers Tigris and Euphrates), also saw the emergence of early complex societies during the succeeding Bronze Age. There is also early evidence from the region for writing and the formation of hierarchical state level societies. This has earned the region the nickname "The cradle of civilization".
Both the Tigris and Euphrates start in the Taurus Mountains of what is modern-day Turkey. Farmers in southern Mesopotamia had to protect their fields from flooding each year, except northern Mesopotamia which had just enough rain to make some farming possible. To protect against flooding, they made levees.
Since the Bronze Age, the region's natural fertility has been greatly extended by irrigation works, upon which much of its agricultural production continues to depend. The last two millennia have seen repeated cycles of decline and recovery as past works have fallen into disrepair through the replacement of states, to be replaced under their successors. Another ongoing problem has been salination—gradual concentration of salt and other minerals in soils with a long history of irrigation.
Prehistoric seedless figs were discovered at Gilgal I in the Jordan Valley, suggesting that fig trees were being planted some 11,400 years ago. Cereals were already grown in Syria as long as 9,000 years ago. Small cats (Felis silvestris) also were domesticated in this region.In addition to cereals, legumes including Peas, Lentils and Chickpea were domesticated in this region.
Linguistically, the Fertile Crescent was a region of great diversity. Historically, Semitic languages generally prevailed in the lowlands, whilst in the mountainous areas to the east and north a number of generally unrelated languages were found including Elamite, Kassite, and Hurro-Urartian. The precise affiliation of these, and their date of arrival, remain topics of scholarly discussion. However, given lack of textual evidence for the earliest era of prehistory, this debate is unlikely to be resolved in the near future.
Links between Hurro-Urartian and Hattic and the indigenous languages of the Caucasus have frequently been suggested, but are not generally accepted.
