Inequality, Agricultural Production and Poverty: With Focus on Large-scale / Small-scale Sugarcane Farms in South Africa.

(2009)

International development agencies have renewed interest over agriculture’s pro-poor potentials. South Africa’s agriculture though contributes less than 3% to GDP, has the highest employment per unit of GDP. The sector is sharply divided into small and large farms. Data reveals an increasing land productivity gap between both types of farms. Using data from various sources1, this paper assesses the agricultural production impacts of inequality and land redistribution, first in the whole agricultural sector, then the sugarcane sub-sector, comparing small-scale and largescale farm performances and considering the causes of the productivity gap. It also analyses the comparative poverty effects of both farm-types. Time series are corrected for unit roots and estimated using robust estimation, which corrects for heteroskedasticity and outliers. Specification tests help to determine the right panel model for sugarcane. The results suggest that inequality (land redistribution) is associated with slower (enhanced) agricultural productivity. This positive effect of land redistribution can be because land constraints in South African large farms may not be binding and therefore the negative impact on large-farms does not dominate. The impact of land redistribution though negative for large-scale and positive for small-scale producers is not significant. This implies that redistribution efforts must be accompanied by significant ease of other constraints facing small farmers. Other inputs like fertiliser and irrigation facilities show more significant impact on small farm production than land alone. Much of the difference in productivity arises from disparity in input use, specifically fertiliser and irrigation. There is possibility of positive external effects from large-scale chemical and labour use to small-scale production as they attenuate the gap in productivities. The finding also suggests the need to strengthen the human capital (particularly education) of small-scale producers. Both large and small-scale sugarcane production have significant poverty reduction effects, but the effect from small-scale production is clearly higher.

Contract Farming, Smallholders and Commercialization of Agriculture in Uganda: The Case of Sorghum, Sunflower, and Rice Contract Farming Schemes.

(2009)

Contract farming has expanded in Uganda due to the promotional efforts of various actors: private, public, and/or international aid agencies. While motives for promoting contract farming may vary by actor, it is argued in this study that contract farming is crucial in the commercialization of smallholder agriculture and hence, poverty reduction in Uganda. However, smallholder farmers in Uganda have reportedly experienced some contractual problems when dealing with large agribusiness firms, resulting in them giving up contract farming. Similarly, agribusinesses have also reportedly encountered some contractual problems when dealing with some smallholder farmers that could have led to the exclusion of the latter from contract farming. Therefore, the main objective of this study was to examine the role of contract farming in the commercialization of smallholder agriculture in Uganda by using sunflower, sorghum, and rice contract schemes as case studies. Specifically, the study sought to characterize the sorghum, sunflower, and rice contract schemes as well as identify benefits and problems associated with them. Primary data were collected by a combined use of survey and informal interview methods. A survey of both contracted and non contracted farmers was conducted in Soroti District (Sorghum), Apac District (Sunflower), and Bugiri District (Rice). Informal interviews were held with agribusiness firms (Nile Breweries Limited, Mukwano Industries, and Tilda (U) Limited), their agents, and support organizations. Data were then analyzed using descriptive statistics and non parametric tests (Chi-square and F-tests). While most of the findings from this study are general in nature, some of them are idiosyncratic to the case studies investigated. It was generally found contract farming contributed a great deal to the commercialization of smallholder agriculture in Uganda, especially in the sorghum (Epuripur) and sunflower sub-sectors. While agribusinesses obtained assured supply of raw materials for their processing needs, smallholder farmers on the other hand had access to critical inputs such as improved seeds and extension services, in addition to access to a guaranteed market for their produce. However, there were still some challenges in the organization and operation of the contract farming schemes. Thus, both agribusinesses and policy makers have separate roles to play in making sure contract farming is properly nurtured for the benefit of smallholder farmers in Uganda.

What determines the price received by farmers? The case of cocoa in Cameroon

(2009)

Various works have demonstrated that small-scale agricultural producers from developing countries do not generally obtain the potential gains linked to marketing. What can be done to help them obtain better prices? In this article, we examine two different solutions: increasing the bargaining power of individual producers and collective marketing through producer organizations (POs). We use data on 2,487 cocoa transactions undertaken by producers in Cameroon during the 2005/2006 season (IITA survey 2006). We first of all explore bargaining theories to identify the determinants of the price received by producers who sell their produce individually, and the, analyse the effect of collective marketing. We show that when the bargaining situation is least favourable to the producers (because the prices are nonnegotiable and there is information asymmetry which favours the traders), the traders seize the entire surplus generated by the trade. In order to improve the prices received by producers, it should be necessary to manage their access to credit (so that they will not be bound to any buyer the had obtained credits from, thus ameliorate arbitrate and negotiate the price), and enable them delay their sale until after the start of the school year (so that traders could no longer know the producers financial need). We also show that selling produce via the POs generally results in a price increase of 9% caused by improvement in a reduction in transaction costs (through economies of scale) and improved bargaining power. The article also examines whether or not the mere presence of a PO in a specific zone enables all the producers in this zone (even those who sell individually) to benefit from higher prices. However, a clear conclusion does not arise in this respect.

Agricultural Productivity and Mortality: Evidence from Kagera, Tanzania

(2009)

We ask whether prime-age adult mortality due to HIV/AIDS decreases the endowment of knowledge for agricultural production in Kagera, Tanzania, reducing total factor productivity. We also quantify how much this negative effect contributes to the decrease in long-term household agricultural income growth compared to the contribution of decreased accumulation of productive assets; household members, land, and livestock. We find that prime-age adult mortality decreases the accumulation of knowledge stock as total factor productivity and the contribution of this negative effect to the decrease in agricultural income growth is larger than the contribution of decreased accumulation of each productive asset.

Agricultural Technology Adoption: A Panel Analysis of Smallholder Farmers’ Fertilizer use in Kenya

(2009)

Africa is the only region where agricultural productivity has continued to decline over the last decades and poverty levels have increased. This has necessitated the need to increase agricultural productivity. One way of increasing agricultural productivity is through introduction and use of improved agricultural technologies. This paper applied a double-hurdle model on a ten-year panel household survey data for 1,275 households to examine determinants of fertilizer adoption and use intensity in Kenya.

Results show that the proportion of households using fertilizer dramatically rose in the last decade while fertilizer application rates increased marginally. Fertilizer use in the drier agro ecological zones is still way below that in the higher agro ecologically potential zones, indicating higher risk involved in and lower profitability of using fertilizer in the drier areas. Econometric estimation results show that age, education, credit, presence of a cash crop, distance to fertilizer market and agro ecological potential are statistically significant in influencing the probability of adopting fertilizer. The strongest determinants of fertilizer use intensity are gender, dependency ratio, credit, presence of cash crop, distance to extension service and agro ecological potential.

The study suggests improving access to gricultural credit by especially low income farmers; concerted efforts to promote fertilizer use among farmers in the drier areas; and government investment in rural infrastructure, efficient port facilities and standards of commerce to reduce the cost of distributing fertilizer, as some of the ways to promote fertilizer use.

Assessing the impact of improved agricultural technologies in rural Mozambique.

(2009)

This paper analyzes the use of improved agricultural technologies, and implications for food security and poverty reduction in rural Mozambique. The results are drawn from a nationally representative household survey covering the agricultural season of 2004/05. As a robustness check, the paper uses three econometric approaches: the doubly robust estimator, regression and matching, and sub-classification and regression. The results show that the impact of improved technologies is positive, conditional on irrigation use. Additionally, the results attest to the importance of increasing agricultural productivity in tandem with improvements on farmers’ ability to store food.

Moving towards pro-poor systems of land administration: Challenges for land and asset distribution in Africa

(2009)

There are three reasons why land policies in Africa are attracting greater amounts of attention. First, it is recognized that enhancing smallholder productivity is critical for sustainable and broad-based growth as well as poverty reduction (World Bank 2007). However, land-related investment, technology adoption, establishment of processing, markets, and value chains, all are unlikely to come about unless land tenure is secure. Moreover, increased productivity will be capitalized in land values and unless explicit attention is devoted to traditional land rights and land access by weaker groups, in particular women, interventions aiming to increase agricultural productivity may have negative social consequences. This is particularly relevant in contexts where current interpretations of customary systems define women's rights only through their relationship with men and women are often unable to inherit land which is considered the property of their husband's lineage. Negative implications for productivity can be severe, in particular if, as almost everywhere, women make a major contribution to agricultural production and its management.

Second, demand for land, and in many cases land prices, have vastly increased with population growth, urbanization, and overall economic development. While higher land values makes land registration more rewarding, leaving land rights undefined increases the risk of having them appropriated by outsiders in a way that may neither be consistent with principles of equity nor conducive to the most productive use of this resource.

Third, in a decentralized setting, land administration can not only help provide public goods and improve government finance but also that are rural areas will not develop based on agriculture alone. Nonagricultural development will imply migration of households out of agriculture that requires secure land rights so as to allow transfer of land rights, either through rental on a temporary basis or through sale, to others who are able to make more effective use of it without the fear of losing it. In many cases, this is now complemented by demand for land by investors who want to use it for food production, bio-fuels, or in anticipation of carbon payments has increased significantly in the wake of recent commodity price booms. It has highlighted that, without clear processes to process requests or assign of land rights, land acquisition by outsiders may end up fostering corruption and leading to inequality and dispossession of traditional land users rather than as a positive force for growth.

This paper examines the theories identifying channels through which land rights can affect socioeconomic outcomes, points to realities which often prevent such effects from materializing, summarizes quantitative evidence on the actual impact of land registration interventions to assess the validity of theoretical arguments, and derives conclusions that can help guide applied work in this area. An example from Ethiopia is used to illustrate the potentially far-reaching impacts of ‘new' models of formalizing land rights and a number of policy conclusions are drawn.

Vulnerability, Risk Management, and Agricultural Development

(2009)

For many poor farmers in developing countries, vulnerability to risk is a dominant feature of their livelihoods. Households' desires to protect themselves against shocks is thought to affect their production and savings decisions. Farmers who are fearful of future loss of earnings may be reluctant to adopt technological innovations with a variable or unknown return. This paper examines the relationship between agricultural development, vulnerability to shocks, and the risk management practices of small farmers in developing countries. It finds that adoption of new agricultural inputs and practices is a combination of both rational and behavioral motives, with peer effects appearing more important through studies of social networks and reinforcement and diffusion effects.

A Market for all Farmers: Market Institutions and Smallholder Participation

(2009)

The transition from subsistence to commercial agriculture, often referred to as the commercialization of agriculture, has long been considered an important part of the agrarian transformation of low income economies and a means of ensuring food security, enhanced nutrition, and enhanced incomes. However, in the face of imperfect markets and high transaction costs, smallholders are rarely able to exploit all the potential gains from commercialization. With the objective of better understanding smallholder participation in markets, the paper proceeds in Section 1 to examine the impact of early reforms on smallholder market participation. In Section 2, we characterize the dimensions of smallholder agriculture that constrain market participation. In Section 3, a conceptual framework for understanding market participation through the lens of market institutions is proposed, followed by an exposition to recent efforts to promote market development in Section 4 and an overview of participation through the market institution of a commodity exchange in Section 5, before proceeding to conclusions in Section 6.
