Non-trade concerns include issues such as consumer interests, livelihoods and the environment. Proposals range from the creation of a specific development box to the modification of the agreement to take into account the different benefits of agriculture. The 60% of Ghana`s labour force working in peasant agriculture in Ghana is mainly active in cocoa and food production. Cocoa is the main agricultural export, although the government has tried to diversify its export base, notably by encouraging non-traditional exports. The stabilization component of AMPs generally includes the devaluation of the national currency (the overvaluation of the exchange rate has been a common cause of non-competitiveness and distortions of domestic prices) with regard to the main currencies traded and the reduction of public expenditure. The objective is to transfer resources from the production of non-negotiable goods to tradable goods. The increased openness fostered by the conclusion of the Uruguay Round negotiations reinforces this trend. As we have argued, the agricultural policy model in developing countries was tax agriculture. Domestic markets have often been heavily protected by import controls. In the years leading up to the Uruguay Round negotiations, trade reforms in developing countries focused on the removal of licensing quotas or restrictions, as well as changes to the tariff structure. Export promotion policy: market access: proposals for tariff reductions or removals, tariff increases and tariff spikes, as well as simplification of tariffs and changes to special guarantees. In a recent report, it was proposed that some developing countries be able to renegotiate related tariffs and increase tariffs in areas important to food security and livelihoods in rural areas, particularly when these tariffs are lower than the tariffs imposed. Another problem is the SPS agreement, under which some developing countries that are unable to meet the requirements of importing countries feel discriminated against, even if they receive goods that do not meet the requirements of their consumers.
