Model revenues equal the total value from the three crops: vanilla, and coffee and tavy (#ha * kg/ha * farm-gate price/kg +/− transportation costs). 2 Commercial cropping patterns (vanilla coffee ratios, Table 1) and yields (Table 3) are based on reported averages in each village.
None, however, enacted subsistence substitution, giving up rice production to purchase this staple with profits from vanilla and coffee crops.
A dominant policy approach to reducing this pressure requires that smallholders abandon tavy and purchase rice from proceeds obtained from their environmentally sustainable commercial crops, vanilla and coffee.
Nonetheless, vanilla remained a marginal crop until the end of the monarchy.
There the cultivators of crops like vanilla, pepper, rubber, coffee, banana and ginger incur unsustainable debt owing to an unfavourable expenditure-return ratio arising from high investment, crop loss and price fall (Vasavi, 2014).
The island's chief crops are vanilla, copra, and coffee.
Cloves, coffee and vanilla beans are cash crops.
Vanilla is a labor-intensive crop that requires even more effort in Madagascar, where it is not a native species.
Squash, coconuts, bananas, and vanilla beans constitute the main cash crops, and other important crops include yams, taro, cassava, corn (maize), watermelons, pineapples, breadfruit, limes, and tomatoes.
