This study deals with the spontaneous spreading of stone bunds in the central Ethiopian highlands, i.e., the adoption and implementation of stone bunds by farmers on their own initiative. The study tests the hypothesis that spontaneously implemented stone bunds, as compared to stone bunds implemented by mass mobilization campaigns, are more integrated with other land management practices and lead to higher yields. Data are collected in the Girar Jarso woreda through field observations and household surveys.

markdownabstractThe aim of the thesis is to understand the impact of large-scale foreign land acquisitions on rural households. The rapid expansion of large-scale land acquisition (LSLA) by foreign investors in developing countries over the past 10 years has precipitated a heated debate over the impacts on rural households in the recipient regions. LSLA brings often much-needed investment to agriculture in developing countries, potentially raising productivity, and creating rental and labour opportunities from which rural households can benefit.

Land rental market development and off-farm employment have important implications for agricultural production. This study examined the effects of land rental market participation, the resulting land tenure contracts, and off-farm employment on the technical efficiency in rice production in rural China, using the one-step stochastic frontier approach. Data from a survey held at household and plot level in three villages in north-east Jiangxi Province were used to estimate the stochastic frontier model.

Time series of vegetation indices (VI) derived from satellite imagery provide a consistent monitoring system for terrestrial plant productivity. They enable detection and quantification of gradual changes within the time frame covered, which are of crucial importance in global change studies, for example. However, VI time series typically contain a strong seasonal signal which complicates change detection. Commonly, trends are quantified using linear regression methods, while the effect of serial autocorrelation is remediated by temporal aggregation over bins having a fixed width.

Keywords: biofuels; land degradation; technology adoption; fuel-savings efficiency; stove R&D; household and community tree investments; fuelwood availability; animal dung; biogas; urban fuel demand; rural hinterlands; northern Ethiopia. Fuel scarcity and land degradation are intertwined problems of global concern. Land degradation affects some 2 billion hectares of land world-wide. In Africa some 500 million hectares of land have been affected by land or soil degradation, including about 65 percent of the continent’s agricultural land.
