Plantations, outgrowers and commercial farming in Africa: agricultural commercialisation and implications for agrarian change

Whether or not investments in African agriculture can generate quality employment at scale,avoid dispossessing local people of their land,promote diversified and sustainable livelihoods, and catalyse more vibrant local economies depends on what farming model is pursued. In this Forum, we build on recent scholarship by discussing the key findings of our recent studies in Ghana, Kenya and Zambia. We examined cases of three models of agricultural commercialisation, characterised by different sets of institutional arrangements that link land, labour and capital. The three models are: plantations or estates with on-farm processing; contract farming and outgrower schemes; and medium-scale commercial farming areas. Building on core debates in the critical agrarian studies literature, we identify commercial farming areas and contract farming as producing the most local economic linkages, and plantations/estates as producing more jobs, although these are of low quality and mostly casual. We point to the gender and generational dynamics emerging in the three models, which reflect the changing demand for family and wage labour. Models of agricultural commercialisation do not always deliver what is expected of them in part because local conditions play a critical role in the unfolding outcomes for land relations, labour regimes, livelihoods and local economies

The new enclosures: critical perspectives on corporate land deals

The contributions to this collection use the tools of agrarian political economy to explore the rapid growth and complex dynamics of large-scale land deals in recent years, with a special focus on the implications of big land deals for property and labour regimes, labour processes and structures of accumulation. The first part of this introductory essay examines the implications of this agrarian political economy perspective. First we explore the continuities and contrasts between historical and contemporary land grabs, before examining the core underlying debate around large- versus small-scale farming futures. Next, we unpack the diverse contexts and causes of land grabbing today, highlighting six overlapping mechanisms. The following section turns to assessing the crisis narratives that frame the justifications for land deals, and the flaws in the argument around there being excess, empty or idle land available. Next the paper turns to an examination of the impacts of land deals, and the processes of inclusion and exclusion at play, before looking at patterns of resistance and constructions of alternatives. The final section introduces the papers in the collection.ESR

Gender, politics and sugarcane commercialisation in Tanzania

This article explores relationships between state, corporate capital and local stakeholders in the political economy of sugarcane from a gender perspective. The findings, based on empirical research at the site of Tanzania’s largest sugarcane producer pre- and post-privatisation, provide insights into the degree to which the estate-outgrower model can be regarded as ‘inclusive’ for women and men. Three aspects of commercial sugarcane production are analysed: land tenure, labour and leadership within canegrowers’ associations. We argue that politico-economic changes in the sector post-privatisation have increased gender differentiation in sugarcane production and consolidated power in the hands of local elites

The natural history of dilated cardiomyopathy: a review of the Heart Muscle Disease Registry of Trieste

Dilated cardiomyopathy (DCM), a heart muscle disease characterized by ventricular dilation and dysfunction, is a leading cause of mortality and morbidity. In the present paper we will consider the main results of studies on the natural history of DCM in 581 consecutive patients prospectively enrolled and systematically followed in the Heart Muscle Disease Registry of Trieste in the last 25 years. In the last decades prognosis of DCM significantly improved over time, mainly as a consequence of optimized treatment with ACE-inhibitors and beta-blockers. However, a strong heterogeneity of prognosis was observed among patients both in familial and sporadic cases. Early diagnosis and treatment allowed to recognize two distinct subgroups, one with a rapidly progressive downhill course, high mortality and urgent indication to heart transplantation, another with a more favorable outcome. Long-term optimized treatment with ACE-inhibitors (in 90% of cases) and beta-blockers (in 87% of cases) was associated with a remarkable clinical improvement in 50% of patients and apparent "healing" in 16% of cases. A systematic and accurate echocardiographic follow-up showed in these cases a significant improvement of the left ventricular ejection fraction (LVEF) with "reverse remodeling", frequently associated with a decrease of severity of functional mitral regurgitation and regression of the restrictive filling pattern. The response to optimal treatment showed a strong relation to long-term outcome. The 8-year transplant-free survival, starting from the evaluation at 2 years, was 31% in patients with persistent NYHA class III-IV, 64% in NYHA class I-II and LVEF 40% and 94% in patients with apparent "healing" (p < 0.0001). Long-term follow-up showed a significant clinical progression of the disease in 33% of cases, independently of the initial clinical response to treatment. Predictive factors of a favorable response to beta-blocker treatment associated with ACE-inhibitors were a history of mild hypertension, an early diagnosis and treatment and the presence of sinus tachycardia. The risk of sudden death was increased particularly in patients with long-term persistent or progressive left ventricular dilation and dysfunction. A rigorous pharmacological approach (optimization of beta-blockers, withdrawal or decrease of dosage of digitalis), and selective non-pharmacological strategy (automated implantable cardioverter-defibrillators for primary prevention in high-risk patients) are potentially effective to decrease the incidence of sudden death during long-term follow-up. In conclusion, the Heart Muscle Disease Registry of Trieste gave us in the last 25 years new insights into the natural history of DCM, underlying the importance of a rigorous and systematic approach both at clinical presentation and during long-term follow-up on optimized medical treatment

Next-generation cellulosic ethanol technologies and their contribution to a sustainable Africa

The world is currently heavily dependent on oil, especially in the transport sector. However, rising oil prices, concern about environmental impact and supply instability are among the factors that have led to greater interest in renewable fuel and green chemistry alternatives. Lignocellulose is the only foreseeable renewable feedstock for sustainable production of transport fuels. The main technological impediment to more widespread utilization of lignocellulose for production of fuels and chemicals in the past has been the lack of low-cost technologies to overcome the recalcitrance of its structure. Both biological and thermochemical second-generation conversion technologies are currently coming online for the commercial production of cellulosic ethanol concomitantly with heat and electricity production. The latest advances in biological conversion of lignocellulosics to ethanol with a focus on consolidated bioprocessing are highlighted. Furthermore, integration of cellulosic ethanol production into existing bio-based industries also using thermochemical processes to optimize energy balances is discussed. Biofuels have played a pivotal yet suboptimal role in supplementing Africa's energy requirements in the past. Capitalizing on sub-Saharan Africa's total biomass potential and using second-generation technologies merit a fresh look at the potential role of bioethanol production towards developing a sustainable Africa while addressing food security, human needs and local wealth creation
