A novel approach to quality assessment of plant health clinics

Since 2003, community-based plant health clinics have been established in several developing countries as a new, low-cost method to provide plant health advice to smallholder farmers who have limited access to advisory services. As the plant clinics are becoming more widespread, there is an increasing need to create basic procedures to regulate clinic operations. This paper describes how the concepts of ‘plant health clinic quality’ evolved from 2006 to 2009 and how a novel framework for quality assessment was developed in Nicaragua, Bangladesh, Vietnam, Bolivia and Uganda. Quality criteria for plant clinics include technical quality, timeliness, staff attitude, feasibility of advice, clinic location, materials, organization and outreach. These criteria show many similarities to those applied successfully in human and animal healthcare. Allowing plant clinic staff and their supervisors to define the quality criteria and monitoring methods themselves has helped raise awareness about clinic performance and improve self-assessment skills. Monitoring visits are being done more consciously and systematically and there are indications that register management and decision-making processes are improving as well as staff motivation. Monitoring protocols and quality assessment are now accepted as an essential component of plant clinic operations to improve clinic performance and accountability to farmers.     

How farmers benefit from plant clinics: an impact study in Bolivia

Between 2000 and 2009, nine plant clinics in three agro-ecological areas of Bolivia (Andes, lowlands and valleys) served about 800 communities in an area roughly 300 × 100km. Over 6000 farmers consulted these clinics with 9000 queries. Many found the advice so useful that they visited the clinics repeatedly. A survey of 238 clinic users found that most adopted the clinics' recommendations. Fruit and vegetable growers who followed the clinic recommendations tended to spend less on pesticides. As for certain crops like potato, citrus and peach palm, a modest increase in pesticides helped improve the quality and quantity of the harvest. Farmers improved their incomes by following the clinics' advice. The poorest farmers enjoyed the greatest increase in income per hectare. This was the first study to explore the impact of plant clinics; future studies need to be improved, for example by obtaining baseline data and by comparing clinic users to their peers who have not used clinics.     

The value of plant genetic diversity to resource-poor farmers in Nepal and Vietnam

Genetic resources for food and agriculture are the biological basis of world food and nutrition security; and they directly or indirectly support the livelihoods of over 2.5 billion people. Genetic diversity gives a species or a population the ability to adapt to changing environments. For resource-poor farmers, adaptive animal breeds, crop varieties and cultivars adapted to particular micro-niches, stresses or uses are the main resources available to maintain or increase production and provide a secure livelihood. The economic value of genetic diversity for productivity and yield traits is discussed in the literature. However, it is difficult to value many other aspects of agricultural biodiversity as these have both direct and indirect values in terms of qualitative traits such as food, nutrition and environmental uses that include adaptation to low input conditions, co-adaptive complexes, yield stability and the consequent reduction of risk, specific niche adaptation, and in meeting socio-cultural needs. Together, the direct and indirect values of genetic resources for resource-poor farmers are expressed in a range of options in the form of the crop varieties and species they use for managing changing environments.

The value of genetic diversity to resource-poor farmers is seldom captured by markets or addressed by the international research agenda. This paper presents lessons learned from our work over 5–10 years in the Asia and Pacific Ocean (APO) region on participatory crop improvement, home gardens and on-farm management of agricultural biodiversity. The lessons illustrate how farmers adapt genetic resources to suit local environmental conditions. The paper focuses on the value of genetic diversity of selected crop species to meet people's food and other needs. Genetic diversity valued by resource-poor farmers is often maintained, selected and exchanged by local social seed networks. Identification of such genetic resources and their custodians is important if international agricultural research is to contribute to the reduction of poverty. The paper highlights some good practices from case studies that illustrate how such genetic resources could be exploited by informal research and development strategies or participatory plant breeding or for marketing value-added products.     

Apparent Gains,Hidden Costs: Examining Adoption Drivers,Yield, and Profitability Outcomes of Rotavator Tillage in Wheat Systems in Nepal

The ‘high speed’ rotavator is used for shallow tillage to create a fine tilth and incorporate crop residues, often with a single tractor pass. Rotavator tillage has spread quickly in many parts of South Asia, despite short-term experimental trials suggesting deteriorating soil quality and crop yield penalties. Evidence of rotavator impacts on farmer fields across soil gradients and time is largely absent. From a farm household survey conducted among wheat farmers in Nepal, we estimate wheat yield and profitability outcomes for rotavator adopters and non-adopters using propensity score matching. We find that rotavator adoption leads to inferior outcomes, despite significant cost savings for land preparation (US$ 11–15 per hectare). With rotavator adoption, farmers lose about 284–309 kg of wheat grain and about US$ 93–101 of profits on average per hectare per season, and these penalties increase with longer-term use of the technology. Adoption of rotavator appears to be driven by the cost and time savings for land preparation. Against this backdrop, new policy and extension efforts are required that discourage rotavator use and favour more sustainable tillage technologies.     

Returns to public sector plant breeding in the presence of spill‐ins and private goods: the case of bean research in Michigan

This article illustrates a methodology for assessing economic returns to a publicly funded breeding program in the presence of private sector investments, and spill‐ins from other contemporary public institutions and past research efforts. The approach consists of determining yield gains from bean improvement research; applying these yield gain estimates to measure benefits attributable to different institutional players and time periods; and then assessing the benefit‐cost ratios of investments in a bean improvement program since 1980 by Michigan State University (MSU). The results indicate that investments in MSU's bean breeding program have yielded benefits to costs ratio in the range of 0.7 to 2.2, depending on the attribution rule used to estimate the benefits. The estimated benefit/cost ratios reported in this study are lower‐bound estimates, as they do not account for potential benefits from area planted to MSU varieties outside of Michigan (spillover effects), which was 1.5 times greater than the area planted to MSU‐bred varieties within Michigan in the period 1998–2002. The implications of the increasingly privatized bean seed markets for the role of public sector research in bean improvement research are discussed.
