agricultural marketing systems and sustainability Study of small scale Andean hillside farms Jairo Castano Propositions (Stellingen) 1. Vertical marketing systems (VMS) are a more appropriate marketing scenario than conventional marketing channels (CMC) when aiming at soil conservation (this thesis). 2. The time horizon of the strategy of the marketing channel leader is a significant factor for farm soil sustainability (this thesis). 3. It is possible to reconcile efforts to increase the profitability and competitiveness of the agricultural sector while improving the management of natural resources (this thesis). 4. Environmental hazards in small-farms in less developed countries are often difficult to control by regulatory approaches only. Marketing mechanisms seem well suited to deal with these hazards because of the economic benefits that help offset investment and effort devoted to land conservation (this thesis). 5. Government intervention aiming at soil conservation in small farms in less developed countries will be better achieved by focusing on the improvement of the marketing environment of small farms (this thesis). 6. A full understanding of the different aspects of soil management is vital for the formulation of appropriate policies towards sustainable farming (this thesis) 7. Increased environmental concerns in consumer markets and growing urbanisation in developing countries imply that markets are increasingly driven by demand rather than by production issues (ISNAR, 1998). 8. Reduction of tariff barriers for forest products could, in the long run, raise stumpage values, which may increase the economic incentives to invest in more efficient wood processing and in better management of production forest in tropical timber producing countries.

Income growth, while being a necessary condition for allowing countries to shift gear from more immediate economic and social concerns to more long run sustainability issues, is not sufficient to reverse environmental degradation. It must be accompanied by adequate environmental policies. Nordtrdm, H., Vaughan, S. (1999). Trade and environment. WTO's special studies. Geneva. 10. The factors that have led Colombia to being a major drug exporter are not only economic and geographic factors but also social, political and cultural factors. The Colombia state has been weak and unable to guarantee basic individual rights such as education, health, work, justice, etc. This has driven society towards individualism, where individual well-being prevails over the society well-being.
