Potential to expand sustainable bioenergy from sugarcane in southern Africa

Journal Articles & Books
December, 2011
Africa

The Cane Resources Network for Southern Africa evaluated how bioenergy from sugarcane can support sustainable development and improve global competitiveness in the region. The assessment of six countries with good contemporary potential for expanding sugarcane cultivation described in this paper was part of their analysis. Its principal objective was to identify land where such production will not have detrimental environmental and/or socio-economic impacts.

Spatial fields' dispersion as a farmer strategy to reduce agro-climatic risk at the household level in pearl millet-based systems in the Sahel: A modeling perspective

Journal Articles & Books
December, 2011

The rainfall pattern in the Sahel is very erratic with a high spatial variability. We tested the often reported hypothesis that the dispersion of farmers' fields around the village territory helps mitigate agro-climatic risk by increasing yield stability from year to year. We also wished to evaluate whether this strategy had an effect on the yield disparity among households in a village. Based on a network of approximately 60 rain gauges spread over 500km² in the Fakara region (Southwest Niger), daily rainfall was interpolated at 300m×300m resolution over a 12-year period.

Land use/cover dynamics and their effects in the Gerado catchment, northeastern Ethiopia

Ethiopia

This paper analyses the land use/cover dynamics of land degradation through the interpretation of aerial photographs (1958 and 1980) and 2006 SPOT-5 satellite image of the Gerado catchment. Other, non-visual data were gathered from personal interview and focus group discussions conducted in 2010 and 2011 with local elders, farmers and development (agricultural extension) agents. The results identified the presence of cultivated and rural settlement land, shrubland, woodland, bare land, grassland, urban built up area and forest.

Analysis of multi-temporal SPOT NDVI images for small-scale land-use mapping

Land-use information is required for a number of purposes such as to address food security issues, to ensure the sustainable use of natural resources and to support decisions regarding food trade and crop insurance. Suitable land-use maps often either do not exist or are not readily available. This article presents a novel method to compile spatial and temporal land-use data sets using multi-temporal remote sensing in combination with existing data sources.

Opportunities and challenges for biodiesel fuel

Journal Articles & Books
December, 2011

Fossil fuel resources are decreasing daily. As a renewable energy, biodiesel has been receiving increasing attention because of the relevance it gains from the rising petroleum price and its environmental advantages. This review highlights some of the perspectives for the biodiesel industry to thrive as an alternative fuel, while discussing opportunities and challenges of biodiesel. This review is divided in three parts. First overview is given on developments of biodiesel in past and present, especially for the different feedstocks and the conversion technologies of biodiesel industry.

Food Security and Fossil Energy Dependence: An International Comparison of the Use of Fossil Energy in Agriculture (1991-2003)

Journal Articles & Books
December, 2011

The serious food crisis in 2007 has reinstated the issue of food security. In particular, it evokes an old set of questions associated with the sustainability of an adequate food supply: are we facing a systemic shortage of arable land for food production? How serious is the oil dependence of food security in relation to peak oil (the point in time when the maximum rate of global oil extraction is reached)? To answer these questions one has to study the role of technical inputs in agricultural production, especially those inputs generated from fossil energy (how much fossil energy is used?

Agricultural value chains and commercial transition in Quang Binh Province, Vietnam

Vietnam

The transition to commercial agriculture is investigated in two communes from three ecological zones (mountain, plains, coastal) in Quang Binh Province, Vietnam. Field investigations were undertaken in late 2006 - early 2007 and again in 2008. One commune in each zone had good road infrastructure and associated market access, while the other had poor road access and was more distant from the market. Two rural households were selected from poor, medium and high wealth categories in each commune, providing 36 case households.

Improving irrigation water operation in the lower reaches of the Amu Darya River – current status and suggestions

Uzbekistan

Irrigated agriculture is widespread in the Central Asian drylands and important for food security of the region. However irrigation practices based on rules made for cotton production on large units do not provide adequate guidance for the now widespread small farms that produce cotton wheat and rice. Excessive unsustainable water use is the consequence. Land and water resource management practices were analysed in 2006 for the irrigated area (approx. 1885 ha) of a water users' association (WUA) as a case study.

Conservation agriculture (CA) in Tanzania: the case of the Mwangaza B CA farmer field school (FFS), Rhotia Village, Karatu District, Arusha

This project was initiated to promote conservation agriculture (CA) in Tanzania so as to improve the food security and rural livelihood of small- and medium-scale farmers through the scaling-up of CA as a sustainable land management (SLM) tool as well as increasing the numbers of SLM-CA farmer field schools (FFS) in communities. The project had two phases from 2004 to 2010. It was funded by a Government of Germany trust fund and implemented by the Food and Agriculture Organization of the United Nations (FAO) and the Ministry of Agriculture in Tanzania.

Characterisation of land types and agro-ecological conditions for production of Jatropha as a feedstock for biofuels in Zimbabwe

Journal Articles & Books
December, 2011
Zimbabwe

There is increasing interest in Zimbabwe in developing a biofuels industry based on the production of biodiesel using Jatropha as the main feedstock. This has led to the introduction of Jatropha as a commercial energy crop in the country. There are plans to grow 1220 km2 of Jatropha which will supply about 365,000 t of seed. This will provide about 110 dam3 of biodiesel required to achieve a blending level of 10% with petro-diesel.

This toolkit is the first of its kind to provide information on promoting and protecting the nutritional status of mothers and children in crises and emergencies. Latin America and the Caribbean is one of the most vulnerable regions in the world to major crises and emergencies. This toolkit aims to improve the resilience of the most vulnerable in times of intensified nutritional needs, most notably pregnant and lactating mothers as well as children less than two years of age.

Bangladesh is one of the most climate vulnerable countries in the world. Situated in the delta of the Ganges, Brahmaputra, and Meghna (GBM) rivers, the country is exposed to a range of river and rainwater flood hazards due to climate variability, the timing, location, and extent of which depend on precipitation in the entire GBM basin. The Government of Bangladesh is fully committed to global climate-change advocacy and action, having already invested heavily in adaptation measures and policies.
