| Jatropha-based biofuels have undergone a rapid boom-and-bust cycle in southern Africa. Despite strong initial support by governments, donors, and the private sector, there is a lack of empirical studies that compare the environmental and socioeconomic impacts of Jatropha’s two dominant modes of production: large plantations and smallholder-based projects. We apply a rapid ecosystem services assessment approach to understand the impact of two Jatropha projects that are still operational despite widespread project collapse across southern Africa: a smallholder-based project (BERL, Malawi) and a large plantation (Niqel, Mozambique). Our study focuses on changes in provisioning ecosystem services such as biofuel feedstock, food, and woodland products... |

| Three case studies from Mexico are presented in which the impacts of the recent introduction of jatropha cultivation for biodiesel production are examined. In Chiapas and Michoacan, local social and environmental impacts were assessed using interviews with key informants and questionnaires directed at three groups of stakeholders: jatropha cultivators, farmers in the same areas who are not cultivating jatropha, and laborers on jatropha farms. Results show that the farmers are primarily motivated to participate by the subsidies offered in a government program in the first 2 years, rather than any proven economic benefit. Our farm budget study indicated that profits would be marginal for these farmers. However, no cases of land alienation were involved, and... |

| ABSTRACT Snap beans have been widely used in organic farming as a good income source and an alternative to diversify production, with increasing use in crop rotation. This work reports the evaluation of 25 bush-type snap beans accessions for their suitability to integrate a breeding program for organic farming, as well as for their resistance to the common bacterial blight (CBB). Agronomic performance was assessed in two field experiments (September-December, 2013; April-June, 2014), in complete blocks at random, while resistance to CBB was assessed in greenhouse, in a completely randomized trial. Plants were challenged with two isolates, one from Xanthomonas axonopodis pv. phaseoli and another from X. fuscans subsp. fuscans. Accessions UEL 402, UEL 405,... |

| As técnicas agroflorestais têm sido desenvolvidas empiricamente e vêm sendo utilizadas há várias gerações pelos índios e o homem do campo em diferentes partes do mundo, mas só recentemente têm despertado interesse como atividade científica (Constantin, 2009). De um modo geral, os sistemas agroflorestais têm sido apontados como de grande relevância, por contribuir com o desenvolvimento de comunidades rurais. No mundo tropical, tais técnicas têm sido utilizadas com efi cácia, principalmente para atender à necessidade de produção de alimentos para o homem e para os animais, associando cultivos agrícolas, exploração pecuária e manejo de espécies florestais. O diferencial inovador desse sistema é a inserção da exploração extrativa vegetal e silvícola no... |

| Many African countries have moved into the production of non-traditional agricultural products, in an effort to diversify their exports and increase foreign currency earnings. However, in order to access developed country markets and urban domestic markets, these products must meet food safety requirements, including protocols relating to pesticide residues, field and pack house operations, and traceability. Faced with stringent food safety requirements, companies that establish production centers in low-income countries might exclude poor farmers, thus negatively impacting the poor. We herein study this issue in the case of the green bean export sectors in three African countries: Ethiopia, Kenya and Zambia. In the short-term, stringent food safety... |

| This paper reports on the findings of a study to investigate market outlet choice decision-making of urban consumers in Vietnam with regards to fresh pork purchases and generate empirical evidence on factors that influence these choices. Data from a survey of 600 consumers in Hanoi and Ho Chi Minh City was used to estimate a multinomial logit model of market outlet choice based on three alternatives: traditional temporary market outlets, permanent open markets, and modern retail outlets. Results suggest that market outlet choice by consumers of fresh pork in urban cities of Vietnam is conditioned by factors related to mobility and level of affluence, time budgets, concerns about food safety and hygiene, proximity to market outlets, and geographical... |

| The dominant view among policy-makers in Sarawak, a resource frontier state in Malaysian Borneo, is that the only viable way to involve smallholders in the oil palm boom that has transformed the agricultural economy of that island is to consolidate them into larger production entities with externally provided management and finance. However, despite lack of government support, the area of smallholder oil palm has increased dramatically in the past decade in those regions with access to roads and palm oil mills. We argue that, once processing infrastructure is in place, oil palm smallholders can readily take advantage of this infrastructure to pursue a profitable livelihood option, with lower cost and greater flexibility than large-scale operations. In this... |

| This study investigated the prevalence and determinants of free-riding in the Ezemvelo Farmers’ Organization (EFO), a group of certified organic crop growers in South Africa, using data gathered in a census survey of its 151 partially and fully certified members. The computed free-riding index scores suggested that free-riding posed a serious threat to the group’s collective marketing efforts. Regression analysis showed that members who were male, poorly educated, aware of loopholes in the grading system, and who did not trust the buyer, were more likely to free-ride. In the longer term, the EFO should address institutionalized free-riding by issuing tradable ownership rights. In the short term, it must engage with the packhouse (buyer) to remove flaws in... |

| Despite its small area and intensively cropped landscape, East Java accounts for 30% of Indonesia’s beef cattle population. About two million households draw on family labour to raise cattle in backyard sheds and small enclosures, largely for cash income. The paper reports on a study in two contrasting sites – irrigated lowlands and rainfed uplands – to explore the constraints facing cattle producers in these environments and possible means to enhance their production systems and incomes. In particular, the paper focuses on the issue of feed supply and the local market that has emerged for agricultural by-products (rice straw, maize stover, and legume residues) and planted forage grasses. The research shows that intensive cattle production can provide a... |

| Soil infertility is a major constraint to food production in the communal areas of Zimbabwe. Smallholders in the region recognize the problems of low soil fertility and have devised ways of coping with them. This study describes the use of farmers taxonomies of themselves and their soils to identify and understand the options they have, and the constraints they face in managing poor soil fertility in Chihota, a sub-humid communal area of north central Zimbabwe. It is part of an effort by a group of agricultural researchers and extensionists working on improved soil fertility technologies, to better integrate their work with farmers in order to expose the latter to promising technologies, get feedback on the technologies merits and feasibility, and help... |
