You modelled the problem below in steps 1 and 2 (or you can download it here modelEco_familyFarm_2.zip<\/a>) :<\/strong><\/p>\n

\u00ab\u00a0A farmer owns 5 ha of land. His family can provide the equivalent of 5 people per year in terms of working time. The number of working days per year and per person is estimated at 100. This farmer can choose between 4 agricultural activities whose costs, yields and prices are shown in the table below. The currency is the rupee.<\/p>\n\n\n\n\n\n\n

For livestock, the value shown in the yield line directly measures the gross product per hectare. A value of 1 was therefore provided in the price line.<\/p>\n

The table below compiles the resource needs for each activity.<\/p>\n\n\n\n\n\n\n

The objective of the farmer is to maximize the global gross margin. The State decides to pass a law concerning water consumption and that it is now limited to 3000 m3 per farm. \u00bb<\/p>\n

It is now possible to buy irrigation water.<\/strong><\/p>\n
