Climate change, food security, and socioeconomic livelihood in Pacific Islands

Peer-reviewed publication
Dezembro, 2015
Fiji

Papua-Nova Guiné

Climate change projections internationally accepted as being reliable indicate that most countries in the Pacific region will suffer large-scale negative impacts from climate change. These impacts are likely to include elevated air and sea-surface temperatures, increasingly unpredictable rainfall patterns, rising sea levels, and intensification of extreme weather events such as tropical cyclones and El Niño-related droughts.

PUBLISHER'S ABSTRACT: The United Nations Declaration on the Rights of Indigenous Peoples was adopted by the UN General Assembly on 13 September 2007. Since then, the importance of the role that indigenous peoples play in economic, social and environmental conservation through traditional sustainable agricultural practices has been gradually recognized.

Allocation or appropriation? How spatial and temporal fragmentation of land allocation policies facilitates land grabbing in Northern Laos

Laos

The Lao Land and Forest Allocation Policy (LFAP) was intended to provide clearer property rights for swidden farmers living in mountainous areas. These lands are legally defined as “State” forests but are under various forms of customary tenure. The policy involves demarcating village territorial boundaries, ecological zoning of lands within village territories, and finally allocating a limited number of individual land parcels to specific households for farming.

Forest policy measures influence on the increase of forest cover in northern Laos

Laos

The government of the Lao People’s Democratic Republic has made great efforts to halt the rapid decline in forest cover by implementing different policy measures, which include measures: to address the causes of the decline in forest cover; to sustainably manage natural forests; and to regenerate degraded forests. In the last decade, forest cover has continued to decrease at a lower rate of just 1% from 2002 (41.5%) to 2010 (40.3%) at national level; however, there has been a net gain of forests in the northern region.

Report in Brief: Assessing Botanical Capacity to Address Grand Challenges in the United States

Botanical capacity plays a fundamental role in solving the grand challenges of the next century, including climate change, sustainability, food security, preservation of ecosystem services, conservation of threatened species, and control of invasive species. Yet critical components of botanical education, research, and management are lacking across government, academic, and private sectors.

multi-scale assessment of human vulnerability to climate change in the Aral Sea basin

Journal Articles & Books
Dezembro, 2015

Vulnerability to climate change impacts is defined by three dimensions of human–environmental systems, such as exposure, sensitivity, and adaptive capacity. Climate change affects various aspects of human–environmental interactions, such as water stress, food security, human health, and well-being at multiple spatial and temporal scales. However, the existing protocols of vulnerability assessment fail to incorporate the multitude of scales associated with climate change processes.

integrated GIS-based interval-probabilistic programming model for land-use planning management under uncertainty—a case study at Suzhou, China

A large number of mathematical models have been developed for supporting optimization of land-use allocation; however, few of them simultaneously consider land suitability (e.g., physical features and spatial information) and various uncertainties existing in many factors (e.g., land availabilities, land demands, land-use patterns, and ecological requirements). This paper incorporates geographic information system (GIS) technology into interval-probabilistic programming (IPP) for land-use planning management (IPP-LUPM).

Determinants of food security under changing land-use systems among pastoral and agro-pastoral households in eastern Ethiopia

Etiópia

A number of previous studies have emphasized the determinants of land-use change, as well as the management of communal lands in the pastoral systems, without assessing the effects of such changes on pastoralists/agro-pastoralists’ food security. Therefore, the objective of this paper was to assess the determinants of food security under changing land use and land management systems—from communal to private investment—using household survey data collected from pastoral and agro-pastoral communities. The data were analyzed using ordinary least-square econometric analysis.

Deforestation of montane cloud forest in the Central Highlands of Guatemala: contributing factors and implications for sustainability in Q’eqchi’ communities

Guatemala

Cloud forest in the Central Highlands of Guatemala provides important ecosystem services for the Q’eqchi’ Maya but has been disappearing at an increasing rate in recent decades. This research documents changes in cloud forest cover, explores some contributing factors to deforestation, and considers forest preservation and food security implications for Q’eqchi’ communities. We used a transdisciplinary framework that synthesized remote sensing/GIS analysis of land cover change, focus group dialogs, and surveys.

Hidden Cost of Eating Meat in South Africa: What Every Responsible Consumer Should Know

Meat production in South Africa is on an increasing trend. In South Africa rising wealth, urbanisation and a growing middle class means South Africans are eating more processed and high-protein foods, especially meat and dairy products. These foods are more land- and water-intensive than fruit, vegetable and grain crops, and further stress existing resources. Traditional agricultural farms cannot keep up with the increasing demand for animal products and these farms are being replaced with concentrated animal feeding operations.

Bioenergy and African transformation

Among the world’s continents, Africa has the highest incidence of food insecurity and poverty and the highest rates of population growth. Yet Africa also has the most arable land, the lowest crop yields, and by far the most plentiful land resources relative to energy demand. It is thus of interest to examine the potential of expanded modern bioenergy production in Africa. Here we consider bioenergy as an enabler for development, and provide an overview of modern bioenergy technologies with a comment on application in an Africa context.
