Linking future ecosystem services and future human well-being

Ecosystem services are necessary, yet not sufficient for human well-being (however defined). Insufficient access to the ecosystem provisioning service of food is a particularly important factor in the loss of human well-being, but all ecosystem services contribute in some way to well-being. Although perhaps long obvious to ecologists, the links between ecosystems and aspects of human well-being, including health, have been less well understood among the social science community. This situation may now be starting to change, thanks in part to the Millennium Ecosystem Assessment (MA). Causality between ecosystem services and well-being is bidirectional; it is increasingly clear that functioning societies can protect or enhance ecosystem services, and accordingly, that societies with impaired well-being (best documented in the case of chronic diseases such as malaria and HIV/AIDS) can also experience a related decline in ecosystem services. The future state of human well-being and of ecosystem services is more than the co-evolution of these two fundamental elements. Human well-being also depends, critically, upon the human institutions that govern relationships between human individuals and groups, and also between humans and ecosystem services. The scenarios working group of the MA found that human well-being is highest in the Global Orchestration scenario, which assumes the fastest evolution of beneficial institutions, and is lowest in the Order from Strength scenario. Human well-being was found to be intermediate in the other two scenarios (Adapting Mosaic and Techno-Garden) even though these scenarios share a much greater recognition of the importance of ecosystem services to human well-being.

Gender differentiation in the analysis of alternative farm mechanization choices on small farms in Kenya

Using multinomial logit we analyze factors that influence the choice of mechanization technologies in Nyanza Province. The results show that farmers are aware of the attributes of the mechanization technologies, and that animal traction is the most commonly used. Gender, formal and informal training of the household head, and technology attributes influence the choice of mechanization technology. This study recommends increased formal and informal training, extension, credit, and tractor hire services to facilitate knowledge transfer, credit, and tractor availability. The study also recommends enactment of laws that increase womens access and control of productive resources.

Does strengthening technical capacity of smallholder farmers enhance adoption of conservation practices? The case of conservation agriculture with trees in Kenya

Despite decades of agricultural extension programmes, participatory research projects and efforts to encourage knowledge integration and sharing, few smallholder farmers are adopting natural resource management (NRM) practices. Using an agroforestry (AF)-based conservation practice known as conservation agriculture with trees as a case study, this study aims at contributing to the growing debate that a properly designed training programme enhances adoption of knowledge intensive NRM practices by providing resource poor farmers with the opportunity to learn, test and adapt such practices to suit their resource needs. To control for endogeneity in participation in training and assess the effect of training on adoption, we estimate an instrumental variable probit model using cross sectional data collected in 2013 from 198 farm households in Machakos district in Kenya. One key message emanating from the study, which is critical for development practitioners who are keen on up-scaling AF based conservation practices through training, is that strengthening technical capacity of smallholder farmers is necessary but it is not in itself sufficient to stimulate adoption of conservation practices. Instead, institutional factors like good road infrastructure that help reduce transaction costs associated with the search for information on technologies and markets and resource endowments in form of labour and land provide synergistic effects. Consequently, complementary strategies such as the introduction of cost effective labour saving technologies and the provision of enabling environment through public–private partnerships for farmers to access the technologies and inputs that are critical for implementing the skills acquired during the training are prerequisites for adoption.

The role of urban-based agriculture on food security: Kenyan case studies

Kenya is rapidly urbanising. In the growing cities and towns, there is an increasing need for food supplies, creating demand for agricultural products. High unemployment rates, urban poverty, and food and nutrition insecurity force some urban dwellers to partly adopt livelihood strategies based on urban agriculture. Presently in Kenya, urban and peri-urban agriculture plays an important role in urban food system, because it enhances livelihood strategies for urban households, not least the poor. Using a sample of 2,009 households, this study characterised urban farming and urban-based rural farming in medium-sized towns of Thika and Kisumu, Kenya. It further assessed food security levels of urban households engaged in farming and households that do not farm. Results demonstrate that more than half of the households produced part of their food, either in urban or rural areas. About 37 per cent and 25 per cent of the respondents produced food in rural and urban areas, respectively. Generally, more of the households engaged in both urban farming and urban-based rural agriculture are more food secure compared with the non-farming households. Urban farming has a potential of improving household food security and provision of fungible income; hence, the practice should be included in the urban food policies.

Devising Effective Strategies and Policies for CSA: Insights from a Panel of Global Policy Experts

In this section, we present the results of a consultation with a panel of leading thinkers on agricultural and climate change policy. We interviewed these experts using a set of questions based on the main findings, conclusions, insights and questions that emerged from our set of case studies and conceptual papers. This section is divided into four parts, each focusing on a set of questions relating to the conclusions that emerged from the case study and conceptual chapters. (i) Focus on changes in production systems as adaptation: priorities and policy actions; (ii) Incorporating climate change into agricultural research and extension; (iii) Taking a close look at national policies affecting risk management: index insurance, safety nets and input subsidies and (iv) Priorities for the future and summary of main points. Overall, there is a fairly high level of agreement amongst the panel members in responding to most of the interview questions, although with some difference in emphasis or applications. However there are also some differences of opinion that emerge from their responses. In this chapter, we discuss the main points made on each of the issues addressed, highlighting the areas of agreement, as well as differences.

Why Pests and Disease Regulation Should Concern Mankind

Nature, through balancing mechanisms, provides ecosystem services, comprising provisioning, regulating, cultural and supporting services for the survival of mankind (MEA, Ecosystems and human well-being: biodiversity synthesis. World Resources Institute, Washington, DC, 2005). The balance and stability is usually upset by interventions or development activities, thereby threatening survival. Maintaining the balance guarantees sustainable development. Pests and disease regulation provides one component of managing the ecosystem. This chapter highlights why pest and disease regulation is important in contributing to sustainable agricultural production and development. Continued multidisciplinary research efforts are needed to enable understanding of the biological interactions between pests, beneficial and host communities on one hand and the interactions between and among cost-effective pest management methods, soil health, climate change, food security and human well-being on the other hand. The holistic approach in developing the understanding of the role of pest and disease regulation in the ecosystem will ultimately contribute to the development of appropriate strategies for the achievement of human well-being

Allocative efficiency in smallholder dairy production in Kenya

This study is aimed at analyzing the economics of smallholder dairy production in the Kiambu District, Kenya. The main objective was to “test for allocative efficiency” of the sample farms. The source of data was from randomly selected dairy farms in Kiambu. An analysis using a Cobb-Douglas form of production function was performed for the major inputs farmers used on their dairy animals. Results revealed that concentrates were being used inefficiently. This implied that there were potential gains which could accrue from reallocation of this resource. However, it was noted that there was efficiency in the use of operating capital, hired and family labour and farm by-products. This implies that, for those inputs used efficiently, further development in agriculture can be achieved only through the introduction of more modern technologies than those currently used. These could include new inputs, apicultural education, special skills and techniques, and competent guidance in farm planning.
