Conventional agricultural practices – especially conventional tillage – are a major driver of soil erosion globally. While soil may not frequently considered a vulnerable natural resource, the erosion and degradation of soils poses a serious threat to food production and the production of numerous otherin situ andex situ ecosystem services. This study provides some of the first evidence on the effectiveness of a payments for ecosystem services (PES) program to encourage the adoption of soil conservation practices, specifically conservation agriculture (CA). Through minimized soil disturbance, permanent soil cover, and diversified crop mix, CA is believed to enhance soil fertility and rehabilitate soil structure, with the resulting preservation of ecosystem service flows. By providing calibrated financial incentives, we demonstrate that it is possible to substantially increase the extent and intensity of CA adoption. What is more, we show that a novel incentive mechanisms that leverages social networks for the consolidation of fragmented land may be more effective at bringing more land under conservation objectives, even if some of the additional land does not officially fall under the purview of the PES program. We also demonstrate that some of the supposed weaknesses hindering the adoption of CA – lower yields in the short-run and higher expenditures on weed control – were not necessarily obstacles in our study area, perhaps suggesting that the provision of subsidies need not continue into perpetuity, but may only be needed to overcome short-term transition costs.

This paper concerns the role of crop diversification in improving household food security in central Malawi. In this country, the agricultural sector is dominated by smallholder farming and rain-fed food production systems that are facing increasing challenges from land degradation and declining soil fertility. Maize is the staple food crop, and as such, the majority of farmers grow it regardless of land suitability. This has led to what scientists have labeled as “maize poverty trap.” In the event of prolonged drought, maize fails thus leaving farmers food insecure. However, research in Sub-Saharan Africa has shown that crop diversification provides smallholder farmers with a diversity of diet, improves their income, and nutrition security. Due to increased cases of malnutrition and food insecurity, in the wake of climate change, government of Malawi has in the past few years intensified extension efforts for crop diversification.

Non-technical summary A major challenge in addressing the loss of benefits and services provided by the natural environment is that it can be difficult to find ways for those who benefit from them to pay for their preservation. We examine one such context in Malawi, where erosion from soils disturbed by agriculture affects not only farmers' incomes, but also damages aquatic habitat and inhibits the storage and hydropower potential of dams downstream. We demonstrate that payments from hydropower producers to farmers to maintain land cover and prevent erosion can have benefits for all parties involved. Technical summary Payments for ecosystem services (PES) schemes provide a mechanism to connect beneficiaries of ecosystem services with those whose actions could provide them. Recent work on PES has demonstrated a priority on matching costs and benefits at the margin, where, on the whole, payments are also low. We draw on dynamic systems theory to demonstrate that reinforcing feedbacks that benefit ecosystem services producers may warrant much higher initial investments in PES programs, and provide evidence of behavioural drivers from a PES trial in Malawi to support these claims. Specifically, in our study, peer effects and improvement to soil structure are processes that can encourage adoption of sustainable land management practices, alongside or in the absence of other incentives. Under this framing, PES programs can be vehicles to shift systems between basins of attraction over a time-limited period, rather than programs necessary for long-term maintenance of services.

This article analyzes maize value chain performance in Malawi and Mozambique using data collected from a market study commissioned by the International Centre for Tropical Agriculture. The results show that although smallholder maize productivity is slightly higher in Malawi, a maize value chain analysis indicates that smallholder maize in Mozambique is more competitive. Mozambique has a relatively higher competitive advantage with regard to maize production because of the relatively lower input costs, perhaps due to its proximity to the coast, which invariably reduces input costs relative to its land-locked neighbor, Malawi. However, smallholder maize productivity is low in both countries, when compared to the regional average. The article concludes that interventions aimed at raising smallholder productivity would invariably make smallholder farmers more competitive. It proposes policy implications aimed at raising the productivity and trade competitiveness of maize, as this will ensure the overall productivity of the maize-based smallholder farming system in the two countries.

Conservation agriculture (CA) is a management paradigm in which soil is covered outside of cropping seasons, minimally disturbed, and recharged with nitrogen-fixing legumes. Finding effective ways to encourage CA is a centuries-old problem playing out acutely today in Sub-Saharan Africa. To better understand this issue, we have collected data on rural livelihoods and CA adoption during a two-year intervention in southern Malawi. The intervention evaluated rates of CA adoption under two different structures of payment and three levels of monitoring. The dataset includes a baseline and endline survey covering 1,900 households, along with surveys conducted with participants opting into the intervention. Baseline and endline questions included modules on farm-level inputs and production at the plot-crop level; plot characteristics; household composition and assets; savings, loans, and other sources of income; neighborhood characteristics; and perceptions regarding CA. Registration questionnaires in the intervention included detailed assessments of recent production in plots being registered to the intervention, and basic information for all other plots; and basic information on household structure and assets.

Agriculture in Malawi is vulnerable to the impacts of changing climate. Adaptation is identified as one of the options to abate the negative impacts of the changing climate. This study analyzed the factors influencing different choices of climate change adaptation strategies by smallholder farmers in Malawi. We took a sample of 900 farmers from all three regions of Malawi, using the multistage sampling procedure study piloted in 2012. We analyzed smallholder farmers’ climate change adaptation strategy choices with multinomial logit regression. Factors that influence the choice of climate adaptation options include age of the household head, gender of the household head, household size, land ownership, credit access, climate change training, and extension visit. Policy thrust should focus on linking farmers to credit institutions, advocating for labor-saving farm technologies, and intensification of climate change training among smallholder farmers.

Malawi faces significant challenges in meeting its future food security needs because there is little scope for increasing production by simply expanding the area under cultivation. One potential alternative for sustainably intensifying agricultural production is by means of conservation agriculture (CA), which improves soil quality through a suite of farming practices that reduce soil disturbance, increase soil cover via retained crop residues, and increase crop diversification. We use discrete choice experiments to study farmers’ preferences for these different CA practices and assess willingness to adopt CA. Our results indicate that, despite many benefits, some farmers are not willing to adopt CA without receiving subsidies, and current farm-level practices significantly influence willingness to adopt the full CA package. Providing subsidies, however, can create perverse incentives. Subsidies may increase the adoption of intercropping and residue mulching, but adoption of these practices may crowd out adoption of zero tillage, leading to partial compliance. Further, exposure to various risks such as flooding and insect infestations often constrains adoption. Rather than designing subsidies or voucher programs to increase CA adoption, it may be important to tailor insurance policies to address the new risks brought about by CA adoption.

This study was designed to analyze drivers of dry common beans trade in Lusaka, Zambia. Specifically, the study analyzed the effect of common bean grain characteristics on bean market price. Data was collected using structured questionnaires from 225 traders stationed in three markets namely: Soweto, Chilenje and Mtendere. Using hedonic pricing, the findings reveal that medium sized grain was an important characteristic which significantly affected the pricing of common bean. For instance, it was observed that medium grain size fetched ZMW1.266 per kilogram (kg) and ZMW 1.042 per kg more than grains of smaller size in the pooled and Soweto market sample, respectively. It was further revealed that yellow, yellow and white color significantly affected the bean price received by traders. Other factors which significantly affected the pricing of beans included age of the trader, being a retail trader and trading at Chilenje market. Given these findings, common bean breeders need to include traders and consumers as important actors whose knowledge can make resourceful impact in varietal development. Furthermore, interventions by policy makers that respond to the social economic needs of traders is recommended to improve bean trade.

This study summarizes the concept of the food-energy-water security nexus (FEW nexus). The aim is to create awareness about the importance of the nexus and to enable stakeholders to consider interconnections between the sectors in their work. The FEW nexus is discussed in the context of Africa south of the Sahara (SSA) — using Malawi and Mozambique as case studies. Even though analyzing food, energy, and water security issues simultaneously is critical given the interconnections, summarizing interventions with the FEW nexus approach in Malawi and Mozambique, we found that there are only a limited number of interventions in place. Additionally, this study reviews macro- and microeconomic models that are able to analyze the FEW nexus. On the macrolevel, especially general equilibrium models are discussed, because they show trade-offs and synergies of nexus interventions at all economic levels. These models can help guide policymakers' understanding of nexus effects ex ante and convince them to think beyond their respective political departments. On the microlevel, the impact of nexus interventions can be assessed with qualitative and quantitative approaches. There are specific challenges for nexus interventions when it comes to aggregation and planning of the targeting. A secondary data analysis of nexus interventions shows that existing data is not sufficient to conduct research specifically related to the FEW nexus. The results of this study will help research programs to reflect the key questions required to enhance adoption of FEW technologies and inform policymakers as they formulate policies that will exploit the strong synergies of food security, energy, and water investments.

This study uses data on 2585 households from the 2010 living conditions monitoring survey (LCMS) and a double-hurdle model to identify factors that affect household decisions on the level of beef expenditure among Lusaka residents. The results confirm that rural households make expenditure decisions that are significantly different from urban households. The results also reveal that factors such as income, size of the household, price of beef, price of chicken and education level of the household head are important determinants that influence both the decision to purchase beef and the level of beef expenditure. Thus, policy design needs to recognize these factors. Policies that aim to target urban households, for example, could increase beef consumption.

This paper discusses tomato value chain performance in Malawi and Mozambique using data collected from a market study commissioned by the International Centre for Tropical Agriculture as part of a regional research on conservation agriculture in maize-based farming systems in Sub-Saharan Africa. The results show that Malawi has a slightly higher competitive advantage in the production of tomato compared to Mozambique. Malawi's relative competitiveness in tomato is mainly due to slightly higher productivity and the cost advantage in labor (low wages) and irrigation costs. The paper proposes policy implications aimed at raising the productivity and trade competitiveness of tomato, as this will ensure the overall productivity of the maize-based smallholder farming systems in the two countries.

Agriculture is vital to Zambia's economic development and is a mainstay for the livelihoods of a large proportion of the population. Agricultural production is mainly dependent on rain-fed hoe cultivation with maize as the principal staple food crop. About 18 percent of national maize production comes from Zambia's Southern province. In order to improve food security and minimize risks associated with heavy dependence on maize, the government of Zambia has been promoting crop diversification. This study analyzed the determinants of crop diversification as well as the factors influencing the extent of crop diversification by smallholder farmers in Southern province. The study used secondary data from the Central Statistical Office of Zambia. Results from a double-hurdle model analysis indicates that landholding size, fertilizer quantity, distance to market, and the type of tillage mechanism adopted have a strong influence on whether a farmer practices crop diversification. Our findings have important implications for policies that are designed to enhance crop diversification. In particular, our results suggest the need for government to consider undertaking policies that will enhance farmers' access to and control over land, that will provide farmers with improved access to agricultural implements like ploughs, and that will bring trading markets closer to farmers.

In contrast to the myriad of empirical work on food demand in other countries, very few studies have considered zero expenditures on some food groups. Those which have attempted have been based on techniques which result in endogeneity and inefficient estimates which in turn may misinform policy calibration. Improving on methodological flaw of previous studies, the present study censors zero expenditures in the first stage using simulation based maximum likelihood multivariate probit. In the second stage, Quadratic Almost Ideal Demand System which allows for a more realistic assumption of curvature in Engels curve is estimated. In turn, food expenditure and price elasticities are derived. In view of the high expenditure elasticities, considering a policy option that would enhance rural consumer income is desirable, since it will result in high consumption thereby providing more incentives for food production.

An initial understanding of socio-economic factors that determine households' decision to keep small ruminants and non-ruminant livestock is imperative when formulating technologies and policies that augment livestock production. Therefore, this article was started with the objective of bringing to light the socio-economic factors affecting the decision of smallholder farmers' households to keep small ruminants and non-ruminant livestock. We used the Malawi Third Integrated Household Survey data, commissioned by National Statistical Office, in which 5 711 households were randomly sampled and interviewed from March 2010 to March 2011. The article fits a simulated maximum likelihood multivariate probit to the data. With respect to the policy variables considered in the analysis, unlike higher education levels and older household heads, younger household heads are more likely to keep small ruminants and non-ruminant livestock. Extension contact and credit access did not promote the keeping of small ruminants and non-ruminant livestock. There is a strong location bias towards keeping small ruminants in the central region of Malawi while there is also a bias against keeping pigs in southern Malawi. Reshaping extension packages toward well rounded crop-livestock messages is an important factor to consider in promoting small ruminant and non-ruminant production in Malawi.

The present study was set out to estimate production efficiency of tomato ( Lycopersicon esculentum L) farmers in the southern region of Malawi’s through efficiency decomposition. A random sample of 72 small-scale farmers was drawn from Balaka district. The findings revealed that farmers in Balaka district have opportunity for productivity gains and cost saving. Mean technical, economic and allocated efficiency were found to be 0.70, 0.57 and 0.82, respectively. Factors like education and credit access augment technical efficiency while credit access, farmer group membership and gender (being male) augment economic and allocative efficiency. Policy thrust like linking small scale farmers to micro-finance institutions for credit access, intensifying family planning programs to reduce family sizes, organizing small scale farmers into groups (cooperatives) and integrating women into training and extension programs would increase production efficiency of small-scale tomato farming in southern Malawi.

There is increased interest in production of Jatropha Curcas as a biodiesel feedstock by both local and international companies. The increased interest is due to problems associated with major energy sources such as diesel and petro and their availability. This study aims at providing an understanding of the socioeconomic factors that influence farmers’ adoption of Jatropha Curcas production as a biofuel technology. The study uses data from 70 Jatropha Curcas farmers in Salima district in Malawi. The results indicated that positive and significant determinants of adoption of Jatropha Curcas production by small scale farmers are gender of the household head, plot size and education level of the household head. Based on extent of adoption, the results show that plot size and education level of the household head are the only significant factors that explain the extent of adoption while marriage status negatively influenced extentof adoption. The study recommends that if Malawi government would like to promote the cultivation of Jatropha crop on commercial basis, consideration for land allocated to Jatropha should be a priority. Promotion may be suitable for large commercial farmers who have lots of land. Keywords: Jatropha Curcas production, adoption, Malawi

This study used a parametric frontier approach to analyze technical, allocative and economic efficiency of smallholder rice farmers. It further explored the factors that influence the efficiency levels of the rice farmers. The study used a trans-log stochastic production function to analyze the technical efficiency. It used the trans-log cost frontier to analyze the economic efficiency. Results from these efficiencies led to the derivation of the allocative efficiency levels. It further used the inefficiency model to analyze the factors underlying efficiency differentials among the sampled farming households. Results revealed an average technical, allocative and economic efficiency levels of 65%, 59% and 53% respectively. This suggests that farmers have a rice yield potential of 35% to be exploited. The average economic efficiency level entails that farmers can raise their profitability or rice production by 47% by adjusting input use. Soil fertility status, access to credit, household size and farmers experience were the factors that influence the efficiency levels of smallholder rice farmers. It is thus recommended that for improved efficiency levels there is need for better policies and strategies that address input and output markets. Furthermore, farmer groups or associations can play a great role in ensuring that farmers get relevant technical advice, credit access as well as learn and share knowledge from each other.
