    Land is the basic resource that is needed by man in order to survive: It provides humans with living space, nutrition and energy resources. The rapid growth of the human population, climate change and pollution on a catastrophic scale has caused the quality of land resources to be compromised. Remote sensing is a useful tool in land cover change detection providing information to decision makers.

    This article assesses the current technical and economic potential of three bioenergy production systems (cassava ethanol, jatropha oil and fuelwood) in semi-arid and arid regions of eight sub-Saharan African countries. The results indicate that the availability of land for energy production ranges from 2% (1.3 Mha) of the total semi-arid and arid area in South Africa to 21% (12 Mha) in Botswana. Land availability for bioenergy production is restricted mainly by agricultural land use, but also by steep slopes and biodiversity protection.

    This paper presents an illustrated guide to the identification of non-pollen palynomorphs (NPPs) preserved in lake-sediment archives from equatorial East Africa. Modern NPPs were recovered from recently deposited surface sediment in 20 small crater lakes in western Uganda, located along environmental gradients of vegetation (moist evergreen and semi-deciduous forest, wooded and open grass savannah), land use (pastoralism, crop agriculture, plantations) and lake characteristics (basin morphometry, water chemistry and aquatic production).

    Social learning plays key roles in sustainable natural resource management; however, studies on its role show mixed results. Even though most current studies highlight positive outcomes, there are also negative effects of social learning with respect to natural resource management. This paper explores the influence of social learning outcomes on the adoption of soil conservation practices in Amba Zuria, Ethiopia. Data were collected through semi-structured interviews, group discussions and in workshops.

    Ethiopia, Africa

    Public agricultural research has been conducted in Africa for decades. While many studies have examined its aggregate impacts, few have investigated how it affects the poor. This paper helps fill this gap by applying a new procedure to explore the ex post impacts of improved maize varieties on poverty in rural Ethiopia. Plot‐level yield and cost changes due to adoption are first estimated using instrumental variable and marginal treatment effect techniques where possible heterogeneity is carefully accounted for.

    Several agro-ecological practices have been developed to increase the range of soil fertility management options available to farmers, but little information is available on their labour input requirement and profitability relative to conventional practices. This study used a multiple visit cost-route method to estimate labour inputs and financial profitability of agroforestry-based and conventional (with and without fertiliser) soil fertility management practices in eastern Zambia.

    Most adoption studies have employed cross-sectional data in a static discrete choice modellingframework to analyze why some farmers adopt at a certain point in time. The static approachdoes not consider the dynamic environment in which the adoption decision is made and thusdoes not incorporate the speed of adoption and the effect of time-dependent elements inexplaining adoption.

    Many developing countries are currently experiencing a rapid expansion of supermarkets. New supermarket procurement systems could have important implications for farming and wider rural development. While previous studies have analyzed farm profit and income effects, possible employment effects have received much less attention. Building on data from a recent survey of vegetable farmers in Kenya, in this article a double-hurdle model of hired labor use is developed and estimated.

    Ghana

    It would appear that the English common law was grafted onto Ghanaian communal societies without taking into account the differences between the early nineteenth-century capitalist economic structures and the egalitarian communal institutions of Ghana. Both systems of law reflect distinctively different economic structures. That oversight laid the foundations for the conflicts between the customary law and practice and the Anglo-American common law, its notions and conceptions of tenure.
