Interventions on the problem of rural development can be in form of plans, projects and programs. Plans don t have clear objectives and rarely have been implemented. Projects are normally made by NGOs, at a small geographic scale. Programs cover more area, and are normally implemented by governments. Examples of the last are programs of health like vaccinations, diffusion of fertilizers, etc.
Examples are roads, phone lines, etc.
For example the program in India of nutrition to assist the worst nourished. A problem of programs is that they are vulnerable to intercept by the powerful sector of society. Like loans that are meant for the poor are taken by their patrons. Other problem is that they are often authoritarian and not adaptable to local realities. Interfere with prices is a powerful weapon to increase rural incomes.
