A Handbook of Tropical Soil Biology

  • Type: Book
  • -
  • Published: 2012-05-04
  • -
  • Publisher: Routledge

This practical handbook describes sampling and laboratory assessment methods for the biodiversity of a number of key functional groups of soil organisms, including insects, earthworms, nematodes, fungi and bacteria. The methods have been assembled and the protocols drafted by a number of scientists associated with the UNEP-GEF funded Conservation and Sustainable Management of Below-Ground Biodiversity Project, executed by the Tropical Soil Biology and Fertility (TSBF) Institute of the International Center for Tropical Agriculture (CIAT). The methods provide a standardized basis for characterizing soil biodiversity and current land uses in terrestrial natural, semi-natural and agroecosystems ...

Use of the Normalized Difference Vegetation Index (NDVI) to Assess Land Degradation at Multiple Scales

  • Type: Book
  • -
  • Published: 2015-11-11
  • -
  • Publisher: Springer

This report examines the scientific basis for the use of remotely sensed data, particularly Normalized Difference Vegetation Index (NDVI), primarily for the assessment of land degradation at different scales and for a range of applications, including resilience of agro-ecosystems. Evidence is drawn from a wide range of investigations, primarily from the scientific peer-reviewed literature but also non-journal sources. The literature review has been corroborated by interviews with leading specialists in the field. The report reviews the use of NDVI for a range of themes related to land degradation, including land cover change, drought monitoring and early warning systems, desertification proc...

Soil and Soil Fertility Management Research in Sub-Saharan Africa

Judicious soil fertility management is crucial for sustainable crop production and food security in sub-Saharan Africa (SSA). This book describes the various concepts and approaches underlying soil and soil fertility management research in SSA over the last fifty years. It provides examples of important innovations generated and assesses the position of research within the research-to-development continuum, including how innovations have been validated with the intended beneficiaries. Using the experience of the International Institute of Tropical Agriculture (IITA) as a case study, the authors analyse how processes, partnerships and other factors have affected research priorities, the deliv...

Forest Resource Policy in Latin America

Forest Resource Policy in Latin America

"Forest Resource Policy in Latin America" gathers the thinking of a score of experts on sustainable use and management of forests, including incentives for investment. The authors tackle the thorny social issues of property rights, deforestation, and forest management and ownership by indigenous people and take a hard look at the trade and environmental issues in forest production that will affect future directions for sustainable forestry development in Latin America. Some argue that the main opportunity to conserve natural forests lies in recognizing and paying for the environmental services they provide. In addition, compensatory measures such as the establishment and better management of strictly protected areas appear to be the best tools to delay the loss of ecosystems and species. Alternative forest concession policies and trade and environmental issues in forest production are also analyzed.

Accélérer la réduction de la pauvreté en Afrique

Le redressement de l’Afrique subsaharienne a été spectaculaire au cours des deux dernières décennies. Après de nombreuses années de déclin, l’économie du continent a commencé à reprendre de la vigueur au milieu des années 90. Grâce à cette croissance macroéconomique, la santé de la population s’est améliorée, le nombre des jeunes fréquentant l’école a augmenté, et le taux d'extrême pauvreté a diminué de 54 % en 1990 à 41 % en 2015. La région a connu moins de conflits (en dépit de ceux qui couvent dans certains pays et du nombre inquiétant des personnes déplacées), un élargissement des libertés politiques et sociales, et des progrès dans l’égalité h...

Accelerating Poverty Reduction in Africa

Sub-Saharan Africa's turnaround over the past couple of decades has been dramatic. After many years in decline, the continent's economy picked up in the mid-1990s. Along with this macroeconomic growth, people became healthier, many more youngsters attended schools, and the rate of extreme poverty declined from 54 percent in 1990 to 41 percent in 2015. Political and social freedoms expanded, and gender equality advanced. Conflict in the region also subsided, although it still claims thousands of civilian lives in some countries and still drives pressing numbers of displaced persons. Despite Africa’s widespread economic and social welfare accomplishments, the region’s challenges remain dau...
