Chapter 5 2. Production and Supply Based Approaches 2.1 Increasing food production and supplies Policies to increase food production and domestic supplies comprise, in principle, the whole set of measures falling under the category of agricultural sector development. They comprise measures in the following fields: * agricultural research, training and extension, * agricultural input supply, * mechanisation, * irrigation, * rural infrastructure and institutions, * land reform, * agricultural marketing and pricing policies, * agricultural credits. These measures are not elaborated here in detail. Rather, reference is made to the abundant literature on the subject. Here, we concentrate on the role of production and supply oriented policies in efforts to improve food security, as referred to, for example, in Commitment number three of the World Food Summit, to "Pursue participatory and sustainable food, agriculture, fisheries, forestry and rural development policies and practices in high and low potential areas, which are essential to adequate and reliable food supplies at the household, national, regional and global levels, and combat pests, drought and desertification, considering the multifunctional character of agriculture" (see Chapter 6, section 5). The chief strategic concept to induce increased food production is the removal of constraints which prevent a better (increased, more intense, more efficient) use of existing human and natural production potentials. Such factors are listed in Table 5.1, together with policy approaches which can reduce these constraints. The specific natural, political, social, and economic conditions in a country or region determine which of the approaches are needed and appropriate and how they specifically should be designed. Some policy measures appear more than once in the table, indicating that the same policy measure may help to alleviate a number of different constraints. - 187-
