Determining the effects of habitat management and climate on the population trends of a declining steppe bird

Journal Articles & Books
december, 2009
Europe

The Little Bustard Tetrax tetrax is one of the most threatened steppe bird species in Europe, due mainly to agricultural intensification. Despite the relative importance of the Iberian population (approximately 50% of the global population) little is known about its dynamics and trends, especially in core distribution areas. This study evaluates the influences of meteorological factors and land management on the oscillations and medium-term trends of two Little Bustard populations in Central Spain.

Tracking the rhythm of the seasons in the face of global change: phenological research in the 21st century

Journal Articles & Books
december, 2009

Phenology is the study of recurring life‐cycle events, classic examples being the flowering of plants and animal migration. Phenological responses are increasingly relevant for addressing applied environmental issues. Yet, challenges remain with respect to spanning scales of observation, integrating observations across taxa, and modeling phenological sequences to enable ecological forecasts in light of future climate change.

Modeling soil organic carbon stocks and changes in a Nepalese watershed

Journal Articles & Books

Nepal

Land use, land use change and forestry activities play an important role in determining whether soil is a sink or source of atmospheric carbon dioxide (CO₂). The effects of land use change on greenhouse gases and climate change are receiving greater attention in many developing countries. We simulated changes in soil organic carbon (SOC) pool over 100 years (1950-2050) under managed dense Shorea forest (DS), rainfed upland (Bari) and irrigated low land (Khet) of Pokhare Khola, a mid-hill watershed of Nepal, using the Century model.

Building resilience to climate change in rain-fed agricultural enterprises: An integrated property planning tool

Journal Articles & Books
december, 2009

In response to a drying climate, an integrated property planning tool was developed over three years to help landowners make better use of available rainfall. A sequence was identified which indicated how parts of each property are affected by soil moisture limitations. The sequence was combined with soil properties to indicate targeted strategies for each location aimed to improve soil moisture availability, biomass utilisation, and long-term viability of the farm or ranching enterprise.

Sudan
Africa

This report on Sudan's Investment Climate Assessment (ICA) provides a baseline assessment of challenges to productivity, diversification and inclusion. Chapter 1 describes some of the questions underlying the three issues of competitiveness, diversification and broad-based growth. Chapter 2 analyzes firm performance and competitiveness. Chapter 3 discusses markets and trust. Chapter 4 describes the role of the financial sector. Chapter 5 analyses the informal sector. Chapter 6 discusses the conflict-affected private sector development.

Forced Displacement

december, 2009

This note discusses the development dimensions of forced displacement, and the potential role of the World Bank to address these dimensions and contribute to durable solutions for group's who have returned from or are in displacement situations. For the purposes of this note, forced displacement refers to the situation of persons who are forced to leave or flee their homes due to conflict, violence, and human rights violations.

Freight Transport for Development Toolkit

december, 2009

The estimate of the United Nations Conference on Trade and Development is that more than 80 percent or close to 8 million tons in 2007, of world freight is transported by sea. Most, if not all, freight transport moves from the producer to the consumer through logistic processes thereby passing a number of nodal points. As for waterborne transport, sea and river ports and terminals form these nodal points where freight is transferred from one mode to another.

Greenhouse Emissions and Climate Change

Reports & Research
Policy Papers & Briefs
december, 2009

There is no longer any serious debate about whether greenhouse gas emissions from human activity are altering the earth's climate. There is also a broad consensus that efficient mitigation of emissions will require carbon pricing via market based instruments (charges or auctioned tradable permits). The remaining controversies stem mostly from economic and technological forecasting uncertainties, disputes about global and intergenerational equity, and political divisions over collective measures to combat climate change.

Southern Mongolia Infrastructure Strategy

Mongolia
Eastern Asia
Oceania

This report is concerned with the development of the infrastructure which is required in order to support proposed mines in Southern Mongolia. In order for the mines to be developed, it will be necessary to provide towns for the new inhabitants, road and rail links to provide supplies and to transport the mines' products to markets, and electricity for the mines' operations. Water resources need to be investigated and supplied to the mines and towns. And as all of the development advances, consideration needs to be given to mitigating any negative environmental and social impacts.

Carbon sequestration in forest trees of the EU as affected by long-term changes of land use.CAB Reviews

Journal Articles & Books
december, 2009
Finland

The biomass of forest vegetation expands in all EU countries. This review analyses the long-term development of forest vegetation and, thereby, the sequestration of carbon in forest biomass in the EU, country by country. The sequestration estimates and their uncertainties are assessed focusing on the period 1990-2006. The most recent estimates are compared with those for earlier times. A case study from Finland is presented, which helps understand the causal mechanisms affecting long-term sequestration of carbon in forest vegetation on a centennial scale.
