Potential to expand sustainable bioenergy from sugarcane in southern Africa

Journal Articles & Books
Décembre, 2011
Afrique

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.

Security of Widows’ Access to Land in the Era of HIV/AIDS: Panel Survey Evidence from Zambia

1. The percentage of households that are headed by widows in rural Zambia increased from 9.4 % to 12.3% between 2001 and 2004.2. Within 1 to 3 years after the death of their husbands, widow-headed households, on average, controlled 35 percent less land than what they had prior to their husband’s death.3. To some extent, older widows are protected against loss of land compared to younger widows.4. Women in relatively wealthy households are particularly vulnerable to losing land after the death of their husbands.5.

Land, power and peace: Tenure formalization, agricultural reform, and livelihood insecurity in rural Rwanda

Journal Articles & Books
Décembre, 2013
Rwanda

Land tenure and agricultural reforms are essential components of postwar development. The importance of land use and management systems to livelihood stability and economic growth is especially relevant in Rwanda, where eighty per cent of the population depends on subsistence agriculture in a rural system plagued by conflict over holdings and decreasing production.

Revolutionary Land Use Change in the 21st Century: Is (Rangeland) Science Relevant?

Journal Articles & Books
Décembre, 2012

Rapidly increasing demand for food, fiber, and fuel together with new technologies and the mobility of global capital are driving revolutionary changes in land use throughout the world. Efforts to increase land productivity include conversion of millions of hectares of rangelands to crop production, including many marginal lands with low resistance and resilience to degradation. Sustaining the productivity of these lands requires careful land use planning and innovative management systems.

Interdependence in rainwater management technologies: an analysis of rainwater management adoption in the Blue Nile Basin

Éthiopie

In the Blue Nile Basin of Ethiopian highlands, rainfall distribution is extremely uneven both spatially and temporally. Drought frequently results in crop failure, while high rainfall intensities result in low infiltration and high runoff causing soil erosion and land degradation. These combined factors contribute to low agricultural productivity and high levels of food insecurity. Poor land management practices coupled with lack of effective rainwater management strategies aggravate the situation.

Unfulfilled farmer expectations: the case of the Insect Resistant Maize for Africa (IRMA) project in Kenya

Afrique

BACKGROUND: Maize is the most important staple food in Kenya; any reduction in production and yield therefore often becomes a national food security concern. To address the challenge posed by the maize stem borer, the Insect Resistant Maize for Africa (IRMA) agricultural biotechnology public-private partnership (PPP) project was launched in 1999. There were, however, pre-existing concerns regarding the use of genetic engineering in crop production and skepticism about private sector involvement.

Land Resources Allocation Strategies in an Urban Area Involving Uncertainty: A Case Study of Suzhou, in the Yangtze River Delta of China

A large number of mathematical models have been developed to support land resource allocation decisions and land management needs; however, few of them can address various uncertainties that exist in relation to many factors presented in such decisions (e.g., land resource availabilities, land demands, land-use patterns, and social demands, as well as ecological requirements). In this study, a multi-objective interval-stochastic land resource allocation model (MOISLAM) was developed for tackling uncertainty that presents as discrete intervals and/or probability distributions.

Japan Agriculture Policy Review

Reports & Research
Octobre, 2007
Japon

Japan, with a population of about 125 million, is a major importer of agricultural products. Japan's mountainous topography limits the area available for farming, with a total cultivated land area of around 4.8 million hectares. Farm holdings are small, averaging just over 1.5 hectares.Japan has producer support levels among the highest in OECD, driven in part by food security concerns and memories of food shortages during World War II and its aftermath.
