eastern, and south-centr<strong>al</strong> areas, which make up<br />
only 44% of <strong>the</strong> nation’s land area. The remaining<br />
one-fourth of <strong>the</strong> population is dispersed in <strong>the</strong><br />
southwestern and northwestern parts. Because of<br />
an active family planning program, including<br />
some restrictions on family size, annu<strong>al</strong><br />
population growth slowed from 2.6% per annum<br />
in <strong>the</strong> late 1960s to just 0.9% per annum in <strong>the</strong><br />
late 1990s.<br />
Recent developments in <strong>the</strong> rice sector<br />
<strong>Rice</strong> is <strong>the</strong> staple food of China and accounts <strong>for</strong><br />
about 35% of tot<strong>al</strong> grain production, which was<br />
345 million t in 2000 (converting paddy to its<br />
milled rice equiv<strong>al</strong>ent). However, wheat is more<br />
<strong>important</strong> in some areas, especi<strong>al</strong>ly in <strong>the</strong> North.<br />
Although rice is still a large part of people’s di<strong>et</strong>s,<br />
its importance has declined considerably in <strong>the</strong><br />
past 15 years. Since 1985, <strong>the</strong> share of tot<strong>al</strong><br />
c<strong>al</strong>ories obtained from rice has f<strong>al</strong>len from 38%<br />
to 30%. During this same period, <strong>the</strong> share of<br />
tot<strong>al</strong> c<strong>al</strong>ories coming from wheat has declined<br />
only slightly, from about 22% to 19%. In terms of<br />
protein, rice and wheat each accounted <strong>for</strong><br />
slightly more than one-fourth of tot<strong>al</strong> protein<br />
intake in <strong>the</strong> late 1980s, but during <strong>the</strong> 1990s this<br />
share declined sharply, and it now stands at<br />
slightly less than one-fifth <strong>for</strong> each cere<strong>al</strong>.<br />
China is <strong>the</strong> world’s largest rice producer,<br />
accounting <strong>for</strong> 32–35% of tot<strong>al</strong> world production<br />
(India has a larger rice area harvested, but lower<br />
per hectare yields). Except <strong>for</strong> Japan and <strong>the</strong><br />
Republic of Korea, rice yields in China are <strong>the</strong><br />
highest in Asia, due in part to favorable growing<br />
conditions. <strong>Rice</strong> area harvested has declined from<br />
its peak of 37 million hectares in <strong>the</strong> mid-1970s<br />
to just over 30 million ha today. The decline in<br />
area has been due to both economic re<strong>for</strong>ms that<br />
reduced government requirements to grow rice<br />
and economic development that increased <strong>the</strong><br />
opportunity cost of land. In recent years, much of<br />
<strong>the</strong> f<strong>al</strong>l in rice area has occurred in coast<strong>al</strong><br />
provinces such as Guangdong and Zhejiang.<br />
Hunan is <strong>the</strong> largest rice producing province, and<br />
<strong>most</strong> rice production is in <strong>the</strong> Yangtze River<br />
V<strong>al</strong>ley (or fur<strong>the</strong>r south) where ample supplies of<br />
water are available. However, rice production in<br />
nor<strong>the</strong>rn China has increased substanti<strong>al</strong>ly in<br />
recent years, with its share of nation<strong>al</strong> production<br />
nearly doubling from 7.6% in 1989 to 13.3% in<br />
1999. Much of this increase has come in<br />
Heilongjiang and <strong>the</strong> o<strong>the</strong>r two nor<strong>the</strong>astern<br />
provinces of Jilin and Liaoning, but production<br />
has <strong>al</strong>so expanded noticeably in Henan and<br />
Shandong.<br />
China regularly imports and exports rice each<br />
year. Imports exceeded exports in 1995 and 1996,<br />
but China has been a n<strong>et</strong> exporter since <strong>the</strong>n. In<br />
1998 and 1999, it was <strong>the</strong> world’s fourth largest<br />
rice exporter (in gross terms, not n<strong>et</strong>), and its<br />
exports helped to stabilize world mark<strong>et</strong> rice<br />
prices in <strong>the</strong> face of a strong El Niño that severely<br />
disrupted production in Indonesia and <strong>the</strong><br />
Philippines.<br />
<strong>Rice</strong> environments<br />
More than 90% of <strong>the</strong> rice area in China is<br />
irrigated, with only relatively sm<strong>al</strong>l areas being<br />
cultivated under rainfed conditions. However,<br />
rice-growing conditions vary because of<br />
topography and wea<strong>the</strong>r. In sou<strong>the</strong>astern China,<br />
high temperature and adequate rainf<strong>al</strong>l make an<br />
ide<strong>al</strong> environment <strong>for</strong> rice during a long growth<br />
period, and many areas grow two crops of rice per<br />
year. In <strong>the</strong> Yangtze River V<strong>al</strong>ley, much of <strong>the</strong><br />
land is planted to a rice-wheat rotation. In<br />
nor<strong>the</strong>astern China, low temperature, a short<br />
growth period, little rainf<strong>al</strong>l, and lack of water<br />
limit <strong>the</strong> rice area. The vari<strong>et</strong>ies grown in this<br />
area are typic<strong>al</strong>ly japonica and are considered to<br />
be of higher qu<strong>al</strong>ity than rice grown in o<strong>the</strong>r<br />
areas. There are some scattered rice areas in arid<br />
and semiarid regions of northwestern China.<br />
Production constraints<br />
Tot<strong>al</strong> area harvested to <strong>al</strong>l crops continues to<br />
increase in China. Area harvested to rice has<br />
declined during <strong>the</strong> past 25 years, however,<br />
because of crop diversification. (<strong>Rice</strong> <strong>for</strong>merly<br />
accounted <strong>for</strong> 26% of <strong>al</strong>l crop area harvested in<br />
<strong>the</strong> mid-1970s, but more recently <strong>the</strong> share is just<br />
20%.) At <strong>the</strong> same time, population continues to<br />
grow by about 13 million people per year. Until<br />
per capita rice consumption begins to decline<br />
because of rising we<strong>al</strong>th accompanied by di<strong>et</strong>ary<br />
diversification (as has happened in Japan, <strong>the</strong><br />
Republic of Korea, M<strong>al</strong>aysia, and Thailand), rice<br />
yields will need to increase to me<strong>et</strong> consumption<br />
demand without resort to imports.<br />
Water shortages in <strong>the</strong> north are ano<strong>the</strong>r<br />
<strong>important</strong> production constraint. Although<br />
nor<strong>the</strong>rn China has only 24% of <strong>the</strong> nation’s<br />
water re<strong>source</strong>s, it contains more than 65% of<br />
China’s cultivated land. While water shortages<br />
