Integration of conservation agriculture in smallholder farming systems of southern Africa: identification of key entry points

A component-omission experiment based on the principle of conservation agriculture (CA) was established on smallholder farms for three seasons in Murehwa and Hwedza districts, Zimbabwe; Barue district in Mozambique; Balaka district and Chitedze Research Station in Malawi, and Monze district in Zambia to identify strategies for improving crop productivity and livelihoods for smallholder farmers. The objective of the experiment was to evaluate the effect of tillage, residue retention, fertiliser application and weed control on maize yield. In addition, the study analysed possible combinations of these factors that could provide a sustainable entry point for intensification through CA. Results showed that fertilisation had the strongest effect on crop yield in both tillage systems; adequate fertilisation is therefore key to success in CA. Retention of crop harvest residues increased yield in no-tillage systems; no-tillage without residues depressed yield by 50% when compared with yields of conventional tillage. A step-wise integration of CA into the smallholder farming systems is proposed as a possible strategy to avoid new constraints on smallholder farms. If resources are limiting, farmers may apply all principles on small areas to overcome the initial demand in resources (labour, fertiliser and residues), and once productivity is raised, they can expand.     

Socio‐economic differentiation from a class‐analytic perspective: The case of smallholder tree‐crop farmers in Limpopo,South Africa

South African agrarian policy aims to integrate smallholder tree‐crop farmers into high‐end value chains with growth and employment potential, generally neglecting socio‐economic differentiation amongst them. This paper aims to analyse socio‐economic differentiation amongst tree‐crop farmers in Vhembe District, Limpopo, using a class‐based analysis based on livelihood diversification and accumulation. Cluster analysis of survey data and semi‐structured interviews reveals that most tree‐crop farmers engage in petty commodity production, internally differentiated by their combination of income sources and livelihood strategies. Farmers' ability to engage in accumulation and upward class mobility is generally severely constrained by limited access to capital. Agricultural diversification offers livelihood potential but limited possibility for accumulation, whereas salaried nonfarm work offers more promising prospects for accumulation but limited livelihood opportunities. A minority demonstrated characteristics of small‐scale capitalist farmers, internally differentiated by their reliance on salaried employment or agricultural production. The findings challenge the notion of an undifferentiated class of market‐oriented smallholders.     

Climate risk,vulnerability and resilience: Supporting livelihood of smallholders in semiarid India

Using panel data from 256 smallholder households from 2006 to 2014 in three semiarid regions India, this study develops a framework for quantifying vulnerability and resilience by accounting for a smallholder household’s ability to adapt and respond to climatic risk. Findings indicate that although smallholders with smaller landholdings are more vulnerable to climatic risk (drought, in our case), they are also more resilient than their counterparts. Results reveal that cropping intensity and crop risk increase the vulnerability of smallholders to climatic risk, but large farms are less vulnerable. Diversification in on-farm enterprises, like livestock units, and off-farm income sources, play significant roles in increasing smallholder households’ resilience to climatic risk. Other drivers of resiliency include the choice of cash and risky crops, borrowing capacity, liquid investments, and the ability to regain yields.     

Do crop purchase programs improve smallholder welfare? The case of Zambia's Food Reserve Agency

Government and parastatal crop purchase programs have regained popularity in sub-Saharan Africa, with many citing improving smallholder farmers’ welfare as a key goal. Yet there is limited empirical evidence on the topic. This paper analyzes the effects of the Zambian Food Reserve Agency's (FRA's) maize purchase activities on smallholder welfare. The FRA buys maize at a pan-territorial price that often exceeds market prices in surplus production areas. Using two household panel survey datasets spanning 15 years and exploiting variation in the scale of FRA activities over time, we employ fixed effects and control function approaches to estimate the effects of a smallholder household's maize sales to the FRA on its welfare, as well as the effects of more intense FRA maize purchase activity in a given district on the welfare of smallholder households in the district. Results suggest positive direct welfare effects on the minority of smallholders that sell to the FRA. We also find that, in the early years of the program, more intense FRA maize purchase activity in a district was associated with reductions in smallholder welfare, particularly among maize autarkic and net buying households. In later years, we find no evidence of such negative effects and some evidence of positive district-level effects on maize net buyers.     

Do Vietnamese upland farmers benefit from high world market prices for maize?

For rural households in the north of Vietnam, maize cropping is the main source of income. In the face of the world market price increases of the recent past, we analyze the regional marketing chain of this commodity qualitatively and econometrically investigating to what extent smallholder farmers in developing countries are affected by international price movements. Vietnamese maize markets are found to be well integrated. Recent price hikes have fully transmitted along the regional supply chain so that farmers profited. Nevertheless, adverse factors such as increasing input prices have neutralized these benefits resulting in a decline in real income of smallholders.     

Smallholder Supply Response to Marketing Board Activities in a Dual Channel Marketing System: The Case of Zambia

In recent years, parastatal grain marketing boards have re‐emerged as important elements of grain markets in eastern and southern Africa, yet little is known about how farmers are responding to their scaled up activities. This article develops a conceptual model of farmers’ production decisions in the context of dual output marketing channels (government and private sector) when output prices at harvest time and the availability of one of the marketing channels are unknown at planting time. It then applies the model to the case of Zambia and uses nationally representative household‐level panel survey data to estimate the effects of the Food Reserve Agency (FRA), the government parastatal maize marketing board, on smallholder crop production and fallow land. The FRA buys maize from smallholders at a pan‐territorial price that typically exceeds market prices in major maize producing areas. Results suggest that increases in the farmgate FRA maize price raise farmer maize price expectations, which induces a supply response. Smallholders respond to an increase in the FRA price by extensifying their maize production. On average, a 1% increase in the FRA price is associated with 0.06% increases in smallholders’ maize area planted and quantity harvested. There is also some evidence that farmers reduce the area of land under fallow in response to FRA incentives but there is no evidence of reductions in the area planted to other crops.     

Tobacco,contract farming,and agrarian change in Zimbabwe

The growth of smallholder tobacco production since 2000 has been one of the big stories of Zimbabwe's post–land reform experience. Yet the implications for agrarian change, and the consequences for new relations between farmers, the state, and agribusiness capital have rarely been discussed. The paper reports on work carried out in the Mvurwi area of Mazowe district in Zimbabwe with a sample of 220 A1 (smallholder) farmers and 100 former farmworkers resident in compounds on the same farms. By going beyond a focus on operational and business dimensions of contract farming, the paper concludes with reflections on the implications for understanding agrarian relations and social differentiation in those areas of Zimbabwe where tobacco growing is now significant, with lessons more broadly on the political economy of contract farming, and the integration of agribusiness capital following land reform.     

Revisiting constraints to smallholder participation in high-value markets: A best-worst scaling approach

We show how policymakers in developing regions can generate richer insights from using the choice experiment method best-worst scaling (BWS) method when ranking policy priorities on an importance scale. More specifically, we adopt BWS to provide an update on constraints that limit the participation of Kenyan horticultural smallholder farmers in modern agricultural value chains. In addition to traditional constraints posed by input market failures and missing institutions, we considered constraints such as trust and familiarity with buyers shown by recent empirical studies to inform smallholders’ market choices. Ascertaining the relevance of these constraints highlights our contribution to the existing literature. We find that farmers consistently rate access to high-quality inputs as their main constraint followed by concerns about access to credit, the high cost of meeting food standards, missing cooperatives, and exploitative intermediaries. Respondents considered insufficient labor, small farmlands, and weak tenure rights as the least important constraints. Age, location, gender, household income, and education influence the relative importance various segments of smallholders place on these constraints. For example, constraints are economic rather than personal for low-income farmers. Counterintuitively, rural smallholders are less likely to perceive poor transportation network as a constraint. Smallholders’ distrust of buyers they interact with is informed by their location and income. In designing intervention initiatives, policies that focus on segments of smallholders are needed for improving smallholder participation in modern agricultural value chains.     

Smallholder agriculture in transition economies

In this paper, we analyse how smallholder farms have evolved during the transition process in former communist countries and how this process has differed across countries and commodities. The role of smallholders in agriculture differs among transition countries, and this diversity is due to a combination of factors, including capital, labour and land endowments, income levels, scale economies, market imperfections, and reform choices. Institutions to access inputs and sell outputs affect the efficiency and survival of smallholders. In the past decade, the share of smallholders in land use and production has declined significantly as younger and more dynamic smallholders have become integrated in modern value chains, whereas older, less dynamic farmers have (semi‐)retired, producing only for household consumption.     

Discouraging Rainforest Transformation: An Ex-ante Policy Impact Analysis

Despite extensive efforts made by national and international certification agencies, Indonesian smallholder farmers’ participation in palm oil certification schemes adoption remains low. A fundamental obstacle is the smallholder practice of rainforest transformation into oil palm plantation which is forbidden by the agencies. In this context, we investigate three policies that could lead to a reduction in rainforest deforestation by smallholders: price premium on certified palm oil; the provision of environmental information; contributor recognition. In order to evaluate the influence of the policies ex-ante, we conduct a social dilemma experiment involving rubber and oil palm smallholders in Jambi Province, Sumatra, Indonesia. The findings indicate that the price premium and provision of context-specific environmental information could reduce rainforest transformation. However, a statistically significant effect of contributor recognition was not found.     

Pesticide Productivity and Transgenic Cotton Technology: The South African Smallholder Case

This paper empirically investigates how the productivity of pesticide differs in Bt versus non‐Bt technology for South African cotton smallholders, and what the implications for pesticide use levels are in the two technologies. This is accomplished by applying a damage control framework to farm‐level data from Makhathini flats, KwaZulu‐Natal. Contrary to findings elsewhere, notably China, that farmers over‐use pesticides and that transgenic technology benefits farmers by enabling large reductions in pesticide use, the econometric evidence here indicates that non‐Bt smallholders in South Africa under‐use pesticide. Thus, the main potential contribution of the new technology is to enable them to realise lost productivity resulting from under‐use. By providing a natural substitute for pesticide, the Bt technology enables the smallholders to circumvent credit and labour constraints associated with pesticide application. Thus, the same technology that greatly reduces pesticide applications but only mildly affects yields, when used by large‐scale farmers in China and elsewhere, benefits South‐African smallholder farmers primarily via a yield‐enhancing effect.     

Transformation of smallholder beef cattle production in Vietnam

This research describes and analyses how smallholder crop livestock farmers in rural Ea Kar, Vietnam, were able to take advantage of the rising demand for meat in urban centres and transform cattle production from a traditional, extensive grazing system to a more intensive, stall-fed system that supplied quality meat to urban markets. The traditional grazing system produced low-quality animals that could only be sold for local consumption. Introduction of the concept of farm-grown fodder production enabled farmers to produce fatter animals, achieving higher sale prices, and reduce labour inputs by moving from grazing to stall-feeding. These benefits convinced farmers, traders and local government that smallholder cattle production could be a viable enterprise and so stimulated stakeholder interest. Within 10 years, the way that cattle were produced and marketed changed considerably. By 2010, more than 3,000 smallholders had adopted farm-grown forages and stall-feeding, and many produced high-quality beef cattle. Traders had been able to develop access to urban markets as farmers were able to produce animals that satisfied the stringent quality requirements of urban markets. In addition to the underlying driver of strong market demand for quality meat, several factors contributed to this transition: (i) a convincing innovation – the use of farm-grown fodder – that provided immediate benefits to farmers and provided a vision for local stakeholders; (ii) a participatory, systems-oriented innovation process that emphasised capacity strengthening; (iii) a value chain approach that linked farmers and local traders to markets; (iv) the formation of a loosely structured coalition of local stakeholders that facilitated and managed the innovation process; and (v) technical support over a sufficiently long time period to allow innovation processes to become sustainable.     

Risk preference and optimal enterprise combinations in Kahuro division of Murang'a district, Kenya

Financing smallholder farming has been one of the major concerns of Kenya's agricultural development efforts. Many credit programs have evolved over the years but with dismal performance. In a study that sought to find the best way to finance smallholder agriculture, it became necessary to analyze and document, in the first place, the farmers' preferred enterprise patterns. Any financial innovations would hence address the preferred patterns. Of particular interest was the effect of risk preference on such patterns, which had been ignored in many previous farm management studies. Murang'a district was chosen as a typical smallholder district. Sample farmers, obtained through cluster sampling, were visited and structured questionnaires administered to cover farm events and physical resources of short rains 1995 to long rains 1996. This formed a basis for formulating the farm patterns. A quadratic programming model was used to analyze observed farm plans. The model incorporates farmers' risk preferences, revenue fluctuations, and resource and subsistence restrictions. The results showed that: (1) changes in risk preference do affect the optimal crop combinations; (2) the typical cropping pattern is rational as the farmer meets both food and cash under modest variability of income; (3) insisting on producing most subsistence food requirements by the farmers reduces efficiency and limits the feasible plans.     

Environmental discounting behaviour of smallholder farmers in Chibombo District,Central Zambia

This study utilised 158 semi structured interviews, three focus group discussions and two key informant interviews to achieve its aim of investigating environmental discounting by smallholder farmers in Chibombo, Zambia. Results suggest that most smallholder farmers were willing to continue using mineral fertilisers in the short to medium term even when they were told there could be potentially negative effects as a result. This result was attributed to the farmers’ experience with neutralising soil acidity through lime application and crop rotations. The proportions of smallholder farmers who would continue using pesticides increased with the period it takes for pesticide induced soil infertility to manifest. The respondents seemed more concerned about effects on the soil that would manifest in five years. Smallholder farmers preferred soil improving practices with short term benefits, and low risk. The proportions of smallholder farmers willing to plant fertiliser trees reduced from 68.5 % when the benefits accrue in five years to about 38 % when said benefits accrue to the next generation. Study recommends that agricultural development interventions should focus on low risk, locally available technologies with shorter term benefits and minimal future costs. Study recommends that agricultural development interventions include innovation of practices with shorter term benefits, minimal future costs and farmer sensitisation on the benefits of sustainable agriculture.     

Addressing the paradox – the divergence between smallholders’ preference and actual adoption of agricultural innovations

Experiences in smallholder contexts indicate frequent mismatches between technologies introduced and needs of farmers who must make complex decisions in reallocating their limited resources under highly risky ecological and market contexts. This study proposes a cost- and time-effective, easy-to-implement approach to identify farmers’ priorities and critical intervention areas, and presents its application in guiding an agroforestry strategy in Rwanda. It was found that different tree species have distinctive enabling vs. constraining conditions under different agroecological contexts in the perspective of smallholder farmers. Tree species preferred by farmers were not necessarily widely adopted if multitudes of conditions were not enabling. The essential conditions for sustainable adoption include: quality materials/inputs are available; technologies are compatible with existing local farming systems; they are resilient to climate risks/resistant to pests-diseases; management is not complicated; and, there is guaranteed access to markets. The results show that there will not be a silver bullet national strategy to scale up agroforestry. Instead a matrix kind of strategies -to promote enabling conditions and address constraining conditions for priority species in specific agroecologies- will be required. The proposed concept should be further refined for wider agricultural technology transfer debates to break the myths of low uptakes by smallholders.     

Unpacking Indonesia’s independent oil palm smallholders: An actor-disaggregated approach to identifying environmental and social performance challenges

Processes of globalization have generated new opportunities for smallholders to participate in profitable global agro-commodity markets. This participation however is increasingly being shaped by differentiated capabilities to comply with emerging public and private quality and safety standards. The dynamics within Indonesia’s oil palm sector illustrate well the types of competitive challenges smallholders face in their integration into global agro-commodity chains. Because of public concern over the poor social and environmental performance of the sector, many governments, companies and consumers are attempting to clean up the value chain through self-regulatory commitments, certification and public regulation. As a result, many of Indonesia’s oil palm smallholders face compliance barriers due to informality and poor production practices, and threaten to become alienated from formal markets, which could in turn lead to a bifurcation of the oil palm sector. Recognizing that many oil palm smallholders lack compliance capacity, myriad public and private actors have begun designing initiatives to address compliance barriers and enhance smallholder competitiveness. However, failure to properly account for the heterogeneity of the smallholder oil palm sector will undermine the effectiveness and scalability of such initiatives. By developing a typology of independent smallholder oil palm farmers in Rokan Hulu district, Riau province, this article reveals the wide diversity of actors that compose Indonesia’s smallholder oil palm economy, the types of compliance barriers they face and the sustainable development challenges they pose. In doing so, this article illustrates how global agro-commodity chains can drive agrarian differentiation and offer new insights into the complex dynamics of agricultural frontier expansion.     

Impact of contract farming on yield,costs and profitability in low‐value crop: evidence from a low‐income country

Lentils, a low‐value and highly nutritious crop, are Nepal's largest pulse cash crop. However, the majority of the nation's smallholders produce lentils on very small plots of land. The large gap in lentil yields between Nepal and other lentil‐producing countries underscores the importance of improving yields and income of smallholders. When it comes to the financial viability of small farms, particularly in developing countries, and globalisation, contract farming (CF) may prove useful in achieving efficiency and profitability in smallholder lentil farms in Nepal. This study employs the propensity score matching approach to examine the effects of the adoption of CF on yields, profitability and costs of smallholder lentil farms in Nepal. Findings from this study reveal that contrary to popular belief, CF adoption by lentil producers in Nepal has a positive and significant effect on per‐hectare revenues, profits and yield and a negative impact on variable and transportation costs. The study finds that only very smallholder lentil farms (0.01‐0.05 ha) benefit from CF.     

Does mixed crop‐livestock farming lead to less diversified diets among smallholders? Evidence from Laos

Malnourishment continues to remain a challenge in developing countries. As the undernourished are largely smallholder farmers, it is widely assumed that farm diversification and mixed crop‐livestock agricultural systems can help alleviate this problem. However, empirical evidence in this context is limited. Hence, we use a two‐year panel's data from Laos to examine whether farm production diversity as well as a mixed crop‐livestock farming system improves household dietary diversity among smallholder farmer. The results from the fixed effects regression indicate that although farm production diversity does lead to a higher dietary diversity, the effect diminishes with continued farm diversification. The counterfactual analysis from the endogenous switching regression reveals that mixed crop‐livestock farming systems do not necessarily enhance dietary diversity. However, we further find that purchasing food from the markets plays an important role in enhancing the dietary diversity of rural smallholder farmers.     

Cash cropping and food crop productivity: synergies or trade‐offs?

The case for promoting export‐oriented cash crops in Africa has generally been based on their direct potential contribution to agricultural productivity and small farmer incomes. A relatively neglected avenue of research concerns the synergistic effects that cash cropping can have on other household activities, including food production. The conventional view that cash crops compete with food crops for land and labour neglects the potential for cash crop schemes to make available inputs on credit, management training, and other resources that can contribute to food crop productivity, which might otherwise not be accessible to farmers if they did not participate in cash crop programs. This article builds on previous research by hypothesising key pathways by which cash crops may affect food crop activities and empirically measuring these effects using the case of cotton in Gokwe North District in Zimbabwe. Analysis is based on instrumental variable analysis of survey data on 430 rural households in 1996. Results indicate that—after controlling for household assets, education and locational differences—households engaging intensively in cotton production obtain higher grain yields than non‐cotton and marginal cotton producers. We also find evidence of regional spill‐over effects whereby commercialisation schemes induce second round investments in a particular area that provide benefits to all farmers in that region, regardless of whether they engage in that commercialisation scheme. The study suggests that the potential spill‐over benefits for food crops through participation in cash crop programs are important to consider in the development of strategies designed to intensify African food crop production.
