The models combine weather and soil information with virtual farming decisions, allowing for tailored growing strategies that reduce risks and uncertainties.
The new welfare and immigration reform acts are likely to produce unintended consequences, including reduced legal immigration and increased incentives for illegal immigrants. Farm employment in rural California is also linked to poverty and a vicious cycle of rural poverty, with immigrants becoming trapped in low-paid labor.
