158 CONCLUSIONS & OUTLOOK In the end, each of can make a difference. Collective small changes at the individual scale, such as eating meat free just one or two days per week, would have big effects on a community, regional, national and international scale. Increased demand for products produced in a sustainable manner can contribute to providing healthy, fresh food to consumers, minimize global sustainability challenges and nurture the environment. hamburg.bio HCU_REAP_MSc._Thesis Sarah_Joseph February_26,_

181 AFNs: CHARACTERISTICS, EXAMPLES & FACTORS TO INCREASE WTP alternative food network (AFN) COMMON CHARACTERISTICS: shortening distances between producers and consumers smaller farm sizes and scale usually focus on organic and/or closed-cycle reliance on alternative food purchasing venues commitment to social, economic & environmental considerations of food production Many times, AFNs are built on long-standing concepts and have been rebuilt with the input of new technologies and social structures. Other times, the traditional model remains, but are increasing in number of schemes and participation. hamburg.bio HCU_REAP_MSc._Thesis Sarah_Joseph February_26,_
