Step 1 model has slightly changed :<\/strong><\/p>\n

\u00ab\u00a0The State decides to implement a regulation policy concerning the use of water and imposes a limit of 7000 m3\u00a0 per farm.\u00a0\u00bb<\/strong><\/p>\n

Reminder : \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

PRICE(Rupees\/ton)<\/td>\n990<\/td>\n3276<\/td>\n1686<\/td>\n1<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\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

The objective of the farmer is to maximize the global gross margin. \u00bb<\/p>\n

Modify the model based on the one you wrote in step 1, or the corrected version (modelEco_familyFarm_1.zip<\/a>), and answer the questions (click on \u201cStart quiz\u201d).<\/strong>
\nIf you need help and\/or to make sure you use the same name for the data :\u00a0 \"\"<\/a>
\n<\/strong><\/p>\n

The results of the previous model were : 0 ha of wheat, 4.89 ha of rice, 0.11 ha of sugar cane and 0 ha for livestock. What do the new results show ?<\/p>\n
