<strong>Milk</strong> <strong>and</strong> dairy products <strong>in</strong> human nutrition<br />
excessive use of nitrogen fertilizer on dairy farms is one of the ma<strong>in</strong> causes of high<br />
nitrate levels <strong>in</strong> surface water <strong>in</strong> OECD countries. Manure runoff <strong>and</strong> leach<strong>in</strong>g from<br />
large-scale dairy operations may also contam<strong>in</strong>ate soil <strong>and</strong> water (<strong>FAO</strong>, 2009).<br />
2.7.2 Impacts on animal <strong>and</strong> human health 8<br />
The <strong>in</strong>creas<strong>in</strong>g concentration of production <strong>and</strong> growth <strong>in</strong> trade are lead<strong>in</strong>g to new<br />
challenges <strong>in</strong> the management of animal diseases. Animal diseases reduce production<br />
<strong>and</strong> productivity, disrupt local <strong>and</strong> national economies, threaten human health <strong>and</strong><br />
exacerbate poverty. The most serious health threat is that of a human p<strong>and</strong>emic. The<br />
economic threats from livestock diseases may be less dramatic, but may also exact<br />
highs cost <strong>in</strong> terms of human welfare <strong>and</strong> pose significant livelihood risks for smallholders.<br />
<strong>Human</strong>s, animals <strong>and</strong> their pathogens have coexisted for millennia, but<br />
recent economic, <strong>in</strong>stitutional <strong>and</strong> environmental trends are creat<strong>in</strong>g new disease<br />
risks <strong>and</strong> <strong>in</strong>tensify<strong>in</strong>g old ones. These risks are the result of a comb<strong>in</strong>ation of rapid<br />
structural change <strong>in</strong> the sector, geographic cluster<strong>in</strong>g of <strong>in</strong>tensive livestock production<br />
facilities near urban population centres <strong>and</strong> the movement of animals, people<br />
<strong>and</strong> pathogens between <strong>in</strong>tensive <strong>and</strong> traditional production systems. At the same<br />
time, climate change is alter<strong>in</strong>g patterns of livestock disease <strong>in</strong>cidence as pathogens<br />
<strong>and</strong> the <strong>in</strong>sects <strong>and</strong> other vectors that carry them enter new ecological zones.<br />
Animal-health <strong>and</strong> food-safety systems are also confronted with new <strong>and</strong> additional<br />
challenges as a result of the lengthen<strong>in</strong>g <strong>and</strong> <strong>in</strong>creas<strong>in</strong>g complexity of supply<br />
cha<strong>in</strong>s <strong>in</strong> the livestock sector, facilitated by globalization <strong>and</strong> trade liberalization.<br />
Meanwhile, <strong>in</strong>creas<strong>in</strong>gly str<strong>in</strong>gent food-safety <strong>and</strong> animal-health regulations <strong>and</strong><br />
private st<strong>and</strong>ards aimed at promot<strong>in</strong>g consumer welfare are creat<strong>in</strong>g challenges for<br />
producers, especially smallholders, who have less technical <strong>and</strong> f<strong>in</strong>ancial capacity to<br />
comply with them.<br />
Many national <strong>in</strong>stitutions for disease control are obliged to respond to an<br />
<strong>in</strong>creas<strong>in</strong>g number of crises <strong>in</strong>stead of focus<strong>in</strong>g on pr<strong>in</strong>ciples of prevention, progressive<br />
disease conta<strong>in</strong>ment, or elim<strong>in</strong>ation of a new emerg<strong>in</strong>g disease before it spreads.<br />
Consequently, the economic impact of diseases <strong>and</strong> the cost of control measures<br />
are high <strong>and</strong> <strong>in</strong>creas<strong>in</strong>g. In addition, sometimes necessary control measures such<br />
as cull<strong>in</strong>g may severely affect the entire production sector, <strong>and</strong> may be devastat<strong>in</strong>g<br />
for the poorest households for whom livestock forms a major asset <strong>and</strong> safety net.<br />
2.7.3 Challenges for smallholder production <strong>and</strong> poverty alleviation<br />
Livestock are important to the livelihoods of many poor people <strong>in</strong> rural areas.<br />
Grow<strong>in</strong>g dem<strong>and</strong> for livestock products <strong>and</strong> technological changes along the food<br />
cha<strong>in</strong> has spurred major changes <strong>in</strong> production systems. As a result, small-scale<br />
mixed production systems are fac<strong>in</strong>g <strong>in</strong>creased competition from large-scale specialized<br />
production units based on purchased <strong>in</strong>puts. These trends present major<br />
competitive challenges for smallholders <strong>and</strong> have implications for the ability of the<br />
sector to contribute to poverty reduction.<br />
