What is China’s major land problem?
stira [4]
Property rights. The rapid growth of cities has led to government transfers of rural land to urban and industrial uses. Inadequate compensation to farmers whose property rights have been poorly defined has fueled growing civil unrest, while urban leaseholders seek to strengthen their new property rights.
Property tax implementation. Recent tax reform has reduced local government revenues and prompted local officials to rely on land sales receipts, fees, and off-budget revenues to finance government expenditures. China’s government is seeking to implement a property tax as a local revenue source to take advantage of the rapid growth of the real estate market.
Farmland preservation. The large amount of land removed from agricultural production by the complex forces of urbanization has exacerbated concerns about farmland preservation, especially related to food security.
Urban planning and development. Rapid urbanization has also resulted in increased urban poverty, housing affordability problems, inequality between urban and rural population groups, regional disparities, and other social and economic challenges. China’s urban planning practices are in need of reform to better reflect market forces and economic behavior.
Environmental sustainability. China’s economic and demographic changes over the past 30 years have been associated with severe environmental degradation. With rapid urbanization forecast over the next decade, there is growing consensus that China must find a more sustainable development model. More sustainable cities are integral to any low-carbon development trajectory.

be over a hot spot, which is why it is the only one of the seven large islands that has active volcanoes. What should be TRUE of
laiz [17]

Answer:

What should be <u>TRUE</u> of the island of <em>Hawaii</em> :

  • Scientists in search of ongoing speciation events are more likely to find them here than on the other six large islands.
  • Its species should be more closely related to those of nearer islands than to those of farther islands.
  • It should have a rich fossil record of terrestrial organisms.

Explanation:

In cases of <em>geographic isolation</em>, and subsequent speciation, produced by dispersal and colonization phenomena we can find the island of Hawaii. Adaptation to these environments can be the trigger for divergence. The <em>large number of species</em> in this archipelago, more than 500, seems to have emerged  through<em> migration</em> and diversification. Many of these are endemic to a nearby island, and the subsequent<em> evolutionary divergence.</em>

The volcanic islands, which have never been in contact with the continent, are especially<u> rich in endemic species; </u>the species that inhabit them are descendants of those who arrived in times past and <u>were able to adapt.</u>

Almost ninety years ago, in the south of the island of Hawaii, they revealed some <u>bones </u>that turned out to be the<u> first bird fossils discovered i</u>n the archipelago. The bones were under a flow of prehistoric lava and on a bed of volcanic ash.

In short, the Island of Hawaii is of great interest to scientists and there are always new developments buried years ago by volcanic activity.
