You modelled the problem below in step 3 (or you can download it here\u00a0 modelEco_familyFarm_3.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

The objective of the farmer is to maximize the global gross margin.<\/p>\n

The State reinforces the law concerning water consumption and imposes a 7000 m3\u00a0 limit per farm. It is possible to buy irrigation water at 2 rupees per m3\u00a0.\u00a0\u00bb<\/p>\n

 <\/p>\n

The farmer\u2019s lack of money (available cashflow constraint) must be taken into account, so that total crop costs must not exceed 20 000 rupees. Modify the model and answer the questions.<\/strong>
