Global drivers setting desertification research priorities: insights from a stakeholder consultation forum

Journal Articles & Books
December, 2014
Global

Recent rapid changes in global scale drivers of desertification, land degradation and drought (DLDD) have two important consequences for drylands. First, changes in these drivers, for example in food and energy prices, make improving interventions in drylands more urgent because of their potential impacts. Second, these changes introduce new knowledge gaps regarding both the potential impacts on social‐ecological dryland systems and the design of options to take advantage of opportunities.

Challenges to Sustainable Development in China: A Review of Six Large-Scale Forest Restoration and Land Conservation Programs

Journal Articles & Books
December, 2014
China

Six national programs—including the Natural Forest Protection Program (NFPP), Sloping Land Conversion Program (SLCP), Desertification Combating Program around Beijing and Tianjin (DCBT), Shelterbelt Network Development Program (SNDP), Wildlife Conservation and Nature Reserve Protection Program (WCNR), and Industrial Timberland Plantation Program (ITPP)—were adopted as means to achieve the Chinese Government sustainable development national policy. While the programs have made promising progress circa 10 yr at the national level, problems exist at the regional and locals levels.

Modeling the long-term natural regeneration potential of woodlands in semi-arid regions to guide restoration efforts

Journal Articles & Books
December, 2014

Understanding forest regeneration at sites previously used for agriculture underlies the establishment of science-based woodlands management policies. This is especially relevant in semi-arid areas, where the tree cover is critical in ameliorating the effects of aridity and in preventing desertification and land degradation. Natural regeneration in semi-arid areas occurs very slowly, which in part explains why it has hardly been studied.

Appraising and selecting strategies to combat and mitigate desertification based on stakeholder knowledge and global best practices in cape verde archipelago

Journal Articles & Books

Cape Verde

Desertification is the most disturbing and detrimental cause of rural vulnerability in Cape Verde, affecting families' material and environmental resources. Combating desertification in Cape Verde is complex because it involves addressing a mixture of endogenous (manual agriculture, fuel wood and fodder extraction, land tenure and steep slopes) and exogenous drivers (high rainfall variability, climate change, prolonged drought or heavy rainfall).

TWENTIETH CENTURY LAND RESILIENCE IN MONTENEGRO AND CONSEQUENT HYDROLOGICAL RESPONSE

Journal Articles & Books
December, 2014
Montenegro

To study the magnitude of land degradation, desertification or resilience in Montenegro throughout the 20th and early‐21st centuries, we rephotographed the landscapes recorded on 48 historical photographs dating back to between 1890 and 1985, and analysed in a semi‐quantitative way the land use and cover changes that had occurred using an expert rating system (six correspondents). Time‐series of hydrology and population density were analysed for the period since 1948 and were compared with the changes observed using repeat photography.

Land use and climate changes and their impacts on runoff in the yarlung zangbo river basin, china

Journal Articles & Books
December, 2014
China

Impacts of land use and climate change on runoff were investigated by studying the runoff in the Yarlung Zangbo River basin, China. Trends in precipitation, mean air temperature, and runoff were analysed by non‐parametric Mann‐Kendall tests. Land‐use changes were examined with land‐use transition matrix and geographic information system tools. Land‐use and climate changes showed several characteristics, including increased reforestation, decreased grassland, retreat of glaciers and increased desertification.

Comparative studies of the distribution characteristics of rocky desertification and land use/land cover classes in typical areas of Guizhou province, China

Journal Articles & Books
December, 2014
China

The Huajiang and Hongfenghu demonstration areas represent typical karst landforms and rocky desertification landscapes in Guizhou, China. These were selected for a comparison of rocky desertification and land use cover. Based mainly on 5� m resolution Spot 5, remote sensing images, topographic maps (1:10,000) and land use maps, the intensity and extent of rocky desertification, and slope characteristics of the two areas were interpreted. Spatial overlay analysis was used to compare the land use/land cover (LULC) and rocky desertification within each.

Green Growth Opportunities for Bhutan

December, 2014

Bhutan has recently made significant
progress in sustaining economic growth and reducing poverty.
In 2012, average per capita household income was somewhat
under USD 2,400/year (Living Standards Measurement Surveys
2012). Growth has averaged around 9 percent per annum over
the past decade and is expected to be on the order of 8
percent per annum over the next five years. According to the
2012 Bhutan Poverty Analysis, 12 percent of the population

GEF Investments on Payment for Ecosystem Services Schemes

December, 2014

The Millennium Ecosystem Assessment
(MEA), The Economics of Ecosystems & Biodiversity study
(TEEB) and the Intergovernmental Platform on Biodiversity
and Ecosystem Services (IPBES) provide a comprehensive and
useful framework to understand human dependence on ecosystem
services and how best to protect these services in
perpetuity. In these three authoritative studies, payment
for ecosystem services (PES) is listed as one of the

Ukraine : Soil Fertility to Strengthen Climate Resilience

December, 2014

Ukraine is renowned as the breadbasket
of Europe thanks to its black soils ( Chernozem black
because of the high organic matter content) which offer
exceptional agronomic conditions. One-third of the worldwide
stock of the fertile black soils, which cover more than half
of Ukraine s arable land, a large variety of climatic zones,
and favourable temperature and moisture regimes, offers
attractive conditions for the production of a large range of

Note on Green Growth for Bhutan

October, 2014

Bhutan has recently made significant
progress in sustaining economic growth and reducing poverty.
Bhutan also has valuable deposits of primary materials
including dolomite, lime stone, gypsum, quartzite, stone,
and marble, which are useful for fabrication of other
materials. Thus, a significant part of Bhutan's current
and prospective economic gains come from use of natural
resources called, green sectors. The basic message in this

Assessing the Potential Consequences of Climate Destabilization in Latin America

September, 2014

Estimating the potential costs of
climate destabilization is not a trivial matter. Potential
climate impacts have multiple consequences, some of which
can be monetized while others are beyond the reach of
standard economic tools. A full assessment of the
implications of climate impacts often cannot be completed
because many of the consequences are only partly known. This
report summarizes data recently made available, through the
