Résumé : | Alentejo region of Portugal is characterised by dry and hot summers, with the rain concentrated in the winter. Total annual rainfall can be low and with a very irregular distribution leading to a very risky dryland agriculture. The farm income of the region has been supported by cultural systems based on winter cereals. Although the low yields, these crops are profitable due to the price and subsidy policies which are not in agreement with the real world market situation. Confronted with the future impacts of the CAP reform and forecasted prices, we consider of great importance to study the transition from the typical dryland agriculture to a situation where the dryland systems are assisted by irrigation. The present work intends to evaluate the viability of investments in irrigation equipment's for several capital and water costs combinations. In order to achieve the stated objective a multi-period linear programming model was built where, besides the investment possibilities, the CAP reform measures were included. The results showed the importance of the conversion from dryland to irrigated systems in order to maintain or increase the farmers income that otherwise would heavily decrease |
