| Jatropha-based biofuels have undergone a rapid boom-and-bust cycle in southern Africa. Despite strong initial support by governments, donors, and the private sector, there is a lack of empirical studies that compare the environmental and socioeconomic impacts of Jatropha’s two dominant modes of production: large plantations and smallholder-based projects. We apply a rapid ecosystem services assessment approach to understand the impact of two Jatropha projects that are still operational despite widespread project collapse across southern Africa: a smallholder-based project (BERL, Malawi) and a large plantation (Niqel, Mozambique). Our study focuses on changes in provisioning ecosystem services such as biofuel feedstock, food, and woodland products... |

| Aquatic agricultural systems in developing countries face increasing competition from multiple stakeholders over rights to access and use natural resources, land, water, wetlands, and fisheries, essential to rural livelihoods. A key implication is the need to strengthen governance to enable equitable decision making amidst competition that spans sectors and scales, building capacities for resilience, and for transformations in institutions that perpetuate poverty. In this paper we provide a simple framework to analyze the governance context for aquatic agricultural system development focused on three dimensions: stakeholder representation, distribution of power, and mechanisms of accountability. Case studies from Cambodia, Bangladesh, Malawi/Mozambique,... |

| Gulella annibiodiversitatis spec. nov. is described from a few scattered localities in montane forest above c. 1300 m in southern-central Malaŵi. It is mainly characterized by a smallish (4.9-6.3 mm high), smooth and generally featureless shell without apertural dentition. Gulella menkhorsti spec. nov., has a small (2.3-2.9 mm high) and smooth shell with a six-fold dentition and is probably a restricted range endemic; so far it has only been recorded from the Mpita Forest in southern Malaŵi. A single smooth and small shell (2.7 mm) with a seven-fold apertural dentition from the Misuku Hills in northern Malaŵi also does represent a new species, Gulella crux spec. nov. Another sample from the same area, introduced as Gulella nuchalis spec. nov., has a... |

| We investigate measurement of market integration of staple food markets in developing countries. The analysis takes the Parity Bound Model as starting point and modifies this model by parameterizing and estimating transaction costs. The specification of transaction costs takes account of transport costs, fixed source costs, fixed destination costs, ad valorem taxes & levies and seasonality an is implemented on the basis of a specific sub-sample of price differentials. Price differentials combined with predicted transaction costs enable the measurement of market integration for each location and each period. The proposed method is applied to the Malawi maize market with monthly data from June 1999 to October 2009 for 26 districts. This period covers two... |

| Concern about humanitarian crises in southern Africa, especially in light of the surge in world food prices since 2007, has been accompanied by calls for direct government action in food markets. This paper reviews how Zambia, Malawi, and Mozambique handled private food markets during the food crises of 2001/02, 2002/03, and 2005/06, which may provide important lessons for the management of future crises. Lack of trust between government and traders can lead to behavior that undermines the interests of each and harms consumers and farmers; Malawi and Zambia have persistently fallen into this trap while Mozambique has partially avoided it. Empirical policy analysis can make an important contribution to resolution only within a consultative process involving... |

| Despite consecutive years of good harvest, Malawi has experienced continuous price escalation of staple food commodities unsolved over the time. The real price of maize in Malawi has increased by 141 percent between 1998 and 2008, and has been rising along with the food prices of many other commodities over this period. This study therefore investigates the determinants of food inflation rate in Malawi and its effect on the economy. Monthly and annual data were collected from National Statistical Office and Reserve Bank of Malawi from 1978 to 2008. Data were analyzed by estimating an error correction model (ECM). The results show that fertilizer prices, crop diversification index, maize prices, diesel prices, real exchange rates and real interest rates... |

| In this paper we analyze the factors that influence the productivity of maize among smallholder farmers. We use farm-household survey data in order to compare the productivity of smallholder maize production under integrated (ISFM) and chemical-based soil fertility management using a normalized translog yield response model. The results indicate higher maize yield responses for integrated soil fertility management options after controlling for the intensity of fertilizer application, labour intensity, seed rate, land husbandry practices as well as selected policy factors. The estimated model is highly consistent with theoretical conditions. Thus we conclude that the use of ISFM improves maize productivity, compared to the use of inorganic fertilizer only.... |

| This study uses nationwide household panel survey data from 1996/97 to 2006/07 to examine trends in fertilizer use on maize by smallholder maize growers. The paper also compares these findings with fertilizer use rates according to other recent surveys in Kenya to assess comparability. We also examine the correlation between household fertilizer use and indicators of welfare such as wealth and landholding size. In addition, we use econometric techniques applied to household survey data to identify the main household and community characteristics associated with fertilizer purchases. Lastly, the study considers alternative policy strategies for maintaining smallholders’ access to fertilizer in the current context of substantially higher world fertilizer... |

| Moral hazard is widely reported as a problem in credit and insurance markets, mainly arising from information asymmetry. Although theorists have attempted to explain the success of Joint Liability Lending (JLL) schemes in mitigating moral hazard, empirical studies are rare. This paper investigates the determinants of moral hazard among JLL schemes from Malawi, using group level data from 99 farm and non-farm credit groups. Results reveal that peer selection, peer monitoring, peer pressure, dynamic incentives and variables capturing the extent of matching problems explain most of the variation in the incidence of moral hazard among credit groups. The implications are that Joint Liability Lending institutions will continue to rely on social cohesion and... |

| This paper applies the Average Treatment Effect (ATE) framework on data obtained from a random cross-section sample of 594 farmers in Malawi to document the actual and potential adoption rates of improved groundnut varieties and their determinants conditional on farmers’ awareness of the technology. The fact that not all farmers are exposed to the new technologies makes it difficult to obtain consistent estimates of population adoption rates and their determinants using direct sample estimates and classical adoption models such as probit or tobit. Our approach tries to control for exposure and selection bias in assessing the adoption rate of technology and its determinants. Results indicate that only 26% of the sampled farmers grew at least one of the... |

| For several reasons, fertilizer subsidies are again popular policy tools. First, there is broad agreement that fertilizer is a critical yet still-underused input for improving productivity and food security in Africa. Second, politicians have felt greater urgency to increase domestic food production since the 2007/08 food price crisis. Third, subsidy programs are highly visible, popular with voters, and viewed as politically beneficial. Fourth, donor budget support has made it easier for governments to pay for subsidies. |

| Input subsidy programs that provide inorganic fertilizer and improved maize seed to small farmers below market rates are currently receiving a great deal of support as a sustainable strategy to foster an African Green Revolution. In recent years numerous countries in Sub-Saharan Africa (SSA) including Ghana, Kenya, Malawi, Mali, Senegal, Tanzania, and Zambia have implemented such programs at substantial cost to government and donor budgets. For example, in 2008 Malawi spent roughly 70% of the Ministry of Agriculture’s budget or just over 16% of the government’s total budget subsidizing fertilizer and seed. In Zambia between 2004 and 2011, an average of 40% of the government’s agricultural sector budget was devoted to fertilizer and maize seed subsidies... |

| In this paper, we analyze the factors that influence the productivity of maize among smallholder farmers, given that unfavourable output and input market conditions throughout the 1990s have compelled smallholder farmers into unsustainable agricultural intensification. We use farm-household survey data in order to compare the productivity of smallholder maize production under integrated (ISFM) and chemical-based soil fertility management using a normalized translog yield response model. The results indicate higher maize yield responses for integrated soil fertility management options after controlling for the intensity of fertilizer application, labour intensity, seed rate, land husbandry practices as well as selected policy factors.
