    choice experiment - contract preferences - modern retail - producer organization - smallholder

    Understanding the preferences of smallholder farmers for contracting can help in making contracts more sustainable. This paper presents the results of a choice experiment (CE) among smallholder farmers in Indonesia to assess their preferences for accepting contracts with modern retail. The CE was based on attributes of actual sales transactions in modern retail and traditional retail channels. A total of 301 vegetable smallholder farmers participated, consisting of 173 farmers participating in traditional markets and 128 in modern retail markets. A random parameter logit model estimates that, in general, smallholders do not prefer contracting with modern retail over spot market selling in traditional retail channels. Most contract attributes are perceived as negative by smallholders. A willingness-to-accept analysis shows that farmers are critical of most contract attributes, particularly those related to quality requirements. Producer organizations (POs) reduce transaction costs and increase smallholders' preference toward contracts. Contract designs that reduce transaction cost, mitigate risks for farmers, provide fair prices, and involve POs are more likely to attract smallholders to modern retail channels.

    East Java - furrow irrigation - smallholder - sprinkler - sugarcane

    Sugarcane farmers in Lumajang in East Java Province have a strong preference of using furrow irrigation instead of sprinkler irrigation. To evaluate the possibility of smallholder sprinkler irrigation as an alternative water-saving irrigation method, the aim of this research is to examine the socio-technical dimension of current irrigation practices of smallholder sugarcane farmers, emphasizing the extent of farmer perspectives and knowledge. As comparison to furrows, a smallholder sprinkler system was designed and evaluated. The sprinkler was expected to fit smallholders' acreage, has low investment costs, is easy to build by locals, and is easy in its operation. The responses, perspectives and expectations of farmers to this smallholder sprinkler system are also discussed. The results indicated that smallholder sugarcane farmers perceive furrow irrigation as the best and low-cost irrigation method. They have already spent money on furrow irrigation investment; however, that investment was seen as a burden for their budgets because smallholders perceived sprinkler irrigation as an expensive irrigation method. In addition, the sprinkler could not satisfy their main expectation because it delivered less water than furrows, meaning the soil was not saturated. This mind-set underlines the slow acceptance process of a relatively new irrigation technology implementation for smallholders in Indonesia.

    Sustainable production and biodiversity conservation can be mutually supportive in providing multiple ecosystem services to farmers and society. This study aimed to determine the contribution of agroforestry systems, as tested by family farmers in the Brazilian Rainforest region since 1993, to tree biodiversity and evaluated farmers’ criteria for tree species selection. In addition, long-term effects on microclimatic temperature conditions for coffee production and chemical and biological soil characteristics at the field scale were compared to full-sun coffee systems. A floristic inventory of 8 agroforests and 4 reference forest sites identified 231 tree species in total. Seventy-eight percent of the tree species found in agroforests were native. The variation in species composition among agroforests contributed to a greater ¿-diversity than a-diversity. Monthly average maximum temperatures were approximately 6 °C higher in full-sun coffee than in agroforests and forests. Total soil organic C, N mineralization and soil microbial activity were higher in forests than in coffee systems, whereas the chemical and biological soil quality in agroforests did not differ significantly from full-sun coffee after 13 years. Given its contribution to the conservation of biodiversity and its capacity to adapt coffee production to future climate change, coffee agroforestry offers a promising strategy for the area.
