The Six Programmatic Thrusts of TSBF-CIAT

Relationship between TSBF-CIAT's objectives and six strategic thrusts.TSBF-CIAT organized its work into six programmatic thrusts, which are related to TSBF-CIAT's objectives (see enlarged figure).

These six programmatic thrusts contribute to the three CIAT's key Development Challenges (DCs).

  1. Intensification and diversification of cropping systems
  2. Managing the genetic resources of soil
  3. Moving from plot to landscape scale
  4. Understanding farm-level social, cultural and gender dynamics
  5. Linking farmers to markets
  6. Collaboration and strengthening NARS capacity

Integrated Soil Fertility Management in the Tropics: From Knowledge to Implementation

TSBF-CIAT's Strategy and Work Plan, 2005-2010

This document represents the strategy for the period 2005-2010 of the Tropical Soil Biology and Fertility Institute of CIAT (TSBF-CIAT).

In recent years, TSBF-CIAT's research for development approach has been based on an Integrated Soil Fertility Management (ISFM) paradigm. ISFM is a holistic approach to soil fertility research that embraces the full range of driving factors and consequences of soil degradation—biological, physical, chemical, social, cultural, economic and political.

TSBF-CIAT will pursue the following objectives under the new strategy:

  • to improve the livelihoods of people reliant on agriculture by developing sustainable, profitable, socially just and resilient agricultural production systems based on ISFM;
  • to develop sustainable land management (SLM) practices in tropical areas while reversing land degradation; and
  • to enhance the human and social capital of all TSBF-CIAT stakeholders for research and management on the sustainable use of tropical soils.

"Smart" Fertilizers and Nitrogen-efficient Crops

An experiment at CIAT headquarters.Researchers at CIAT and the Japan International Research Center for Agricultural Sciences (JIRCAS) are moving full steam ahead to exploit a rare biochemical phenomenon from some tropical pasture grasses—biological nitrification inhibition (BNI). Triggered by chemical compounds released from the roots of an African grass widely grown in South America, this natural process, once harnessed, is expected to make nitrogen fertilizer use far more efficient.

Integrating Folk and Formal Soil Ecology

Members of the Mukhome farmer field school in Kenya.For Kenya's small farmers, soil fertility management is not just a matter of maintaining a chemical balance in the topsoil but rather brings into play their knowledge of soil ecology. With support from Canada's International Development Research Centre (IDRC), researchers in CIAT's Tropical Soil Biology and Fertility (TSBF) Institute are testing an interactive learning strategy with four communities in western Kenya to promote dialog between farmers' "folk" ecology and formal scientific knowledge.

This approach contrasts with conventional agronomic research methods, which often ignore local knowledge systems. While not a panacea, farmers' knowledge about factors such as soil types, nutrient content, composting, and crop response to organic and inorganic amendments is vital, since it guides their decisions about farming.

Building an Arable Layer of Soil in the Savannas

Improved tillage for the acid-soil savannas of South America.Brazil, Colombia, Venezuela, and other countries endowed with vast tropical savannas have great expectations for these resources. They see them as a last frontier of arable land, a means of expanding crop production and generating regional economic wealth within their borders. But, as the research experience of CIAT and other scientists has demonstrated, this will be nothing but a pipe dream unless the currently infertile, degraded soils of the savannas can first be built up-almost from scratch.

Savanna soils are often acidic, high in aluminum (which is toxic to plants), and low in organic matter. Without dramatic improvements in the physical, chemical, and biological characteristics of these Oxisols and Ultisols, it won't be possible to introduce sustainable, no-till crop agriculture.

Workshop on Adapting Crops and Forages to Acid Soils

The workshop on "Advances in improving acid soil adaptation of tropical crops and forages, and management of acid soils" was jointly organized by EMBRAPA, CIAT, and IRD. Funded by the Brazilian Government, the workshop was held in Brasília, October 2005. The 30 participants reviewed advances made in (1) adapting major food and feed crops to acid soils, and (2) managing acid soils. The main topics discussed included identifying, screening, and breeding for aluminum resistance in crop and forage germplasm; the physiological and molecular mechanisms involved in aluminum resistance and low phosphorus tolerance; how native Cerrado plants adapt to acid soils; and soil management and agropastoral production for no-tillage systems in acid-soil regions. The participants noted the dramatic adoption of Brachiaria brizantha cv. Marandu, which is spittlebug resistant. Opportunity was taken to strengthen and plan collaborative activities, and identify future research needs.

An Advanced Training Workshop on DSSAT Version 4

This event, to be held in October 2005, follows up the Arusha 2004 workshop on the DSSAT v4. DSSAT v4 assesses crop production, nutrient management, climatic risk, and environmental sustainability. Participants will use their own datasets to determine the models' accuracy for specific problems; analyze management alternatives for the short or long term; assess economic risks and environmental impacts associated with agricultural production; and use DSSAT with socioeconomic analyses to link on-farm information with biophysical models. Case studies developed by the participants will be collated into a special publication. Refresher sessions will also be offered before the workshop itself. The event is organized by CPWF, AfNet, and DMP; the presenter is ICASA; and trainers will be from the Universities of Florida and Georgia (USA) and ICRISAT-Bamako.

Workshop on Participatory Approaches to Research and Scaling Up

Web problem solving and teamwork exerciceThirty-seven scientists from 17 African countries took a 12-day course to learn about farmer participatory research (FPR) and scaling up (SU). These approaches would help increase the relevance and impact of their R&D work on integrated soil fertility management. Themes dealt with the concepts, principles, methodology, and skills of effective FPR and SU; skills in participatory data collection and analysis; how to communicate and disseminate successful results and technologies; conduct participatory marketing; and scale both up and out. Held in Nairobi, Kenya, in September 2005, the workshop was facilitated by CIAT's TSBF and ERI, and other entities. It was organized by AfNet (of TSBF), ICRISAT, and CERAAS; and sponsored by CTA, CORAF/WECARD, ADB, UNEP-GEF, DMP, CPWF, and PRGA Program.

'Modeling Nutrient Management in Tropical Cropping Systems' Conference Proceedings Published

In tropical regions, organic materials are often more important than fertilizers in maintaining soil fertility, yet most crop models are unable to take account of the level and quality of organic inputs that farmers use. These proceedings report the achievements of a project supported by the Australian Centre for International Agricultural Research (ACIAR) that aims to test and improve the capability of the Agricultural Production Systems Simulator (APSIM) to predict the decomposition of various organic inputs, dynamics of nitrogen and phosphorus in soil, and their effect on crop yields. The project was implemented through the CGIAR's SWNM program in collaboration with the Commonwealth Scientific & Industrial Research Organisation (CSIRO) and the Queensland Department of Primary Industries (QDPI).

A New International Initiative to Tap Below-Ground Biodiversity

CIAT’s Tropical Soil Biology and Fertility (TSBF) Institute, based in Nairobi, Kenya, will coordinate an ambitious new project—"Conservation and Sustainable Management of Below-Ground Biodiversity"—with funding from the Global Environment Facility, or GEF. Through the project a consortium of institutions in seven countries—Brazil, Côte d’Ivoire, India, Indonesia, Kenya, Mexico, and Uganda—will develop improved methods for conserving and managing the extraordinarily diverse community of soil organisms (including bacteria, fungi, protozoa, and invertebrate animals), which represent a huge segment of global biodiversity. This work will lead to improvement in vital environmental services, such as regulation of greenhouse gas emissions, and provide farmers in the tropics with new options for intensifying agriculture while protecting natural resources.

For more information see the news release from the United Nations Environment Programme (UNEP) and a short project description.

 


International Soil Fertility Symposium

Integrated Soil Fertility StrategyAn international symposium on helping farmers raise soil fertility was held on 17-21 May 2004 at Yaoundé, Cameroon. Organized by the African Network for Soil Biology and Fertility (AfNet) of CIAT's Tropical Soil Biology and Fertility (TSBF), the event had three central objectives: (1) to review the state of the art in integrated soil fertility management (ISFM), (2) to propose strategies for scaling up technologies that enhance soil fertility, and (3) to broaden awareness of new initiatives in natural resource management, with emphasis on the concept of integrated agricultural research for development (IAR4D).

New Alliance to Raise the Fertility of Tropical Soils

The global cause of halting tropical soil degradation has a new but familiar ally. It's the Alliance for Integrated Soil Fertility Management in Africa, formed recently by the former TSBF Programme, CIAT, and the International Centre for Research in Agroforestry (ICRAF). As a first step in creating the alliance, the TSBF Institute of CIAT was established under an agreement signed in December 2001 at Center headquarters in Colombia. Subsequently, CIAT and ICRAF agreed on terms for a wider arrangement that fully integrates the soils research of the three founding organizations. Scientists from these organizations met during early March with technical advisers from interested donor agencies for a 3-day strategy-development workshop (further details).

Soil Fertility Degradation in Sub-Saharn Africa: Leveraging Lasting Solutions to a Long-Term Problem

A Workshop at the Rockefeller Foundation Bellagio Conference Centre, March 4th-8th, 2002

Soil fertility degradation has been described as the single most important constraint to food security in sub-Saharan Africa (SSA). Despite proposals for a diversity of solutions and the investment of time and resources by a wide range of institutions it continues to prove a substantially intransigent problem. Three international agricultural research centers (IARCs), CIAT, TSBF, and ICRAF, have recently joined forces in an alliance targeted at tackling this challenge. The objectives of the workshop were to: (1) Present the new alliance between the three organizations, (2) Review tropical soil degradation and proposed solutions, (3) Identify mechanisms to sustain an integrated attack on this long-term problem.

Investing in Farmer's Future

An open alliance to restore soil fertility in Africa

Last March, as world leaders meeting at Monterrey, Mexico, implored rich countries to double their development aid, a group of international agricultural researchers was building the case for greater investment in the restoration of tropical soils, especially in Africa. Only by raising soil fertility, the scientists argued, will the 85 percent of Africa’s poor who live in rural areas be able to achieve food security and increase farm incomes. To the extent that rural communities succeed in making agriculture more dynamic and competitive, any new development aid that does come their way should do a lot more good.

In a determined effort to create the conditions for that success, three international agricultural research organizations have recently joined forces by establishing the Alliance for Integrated Soil Fertility Management in Africa. The founding partners are CIAT, the Tropical Soil Biology and Fertility (TSBF) Programme, and the International Centre for Research in Agroforestry (ICRAF).

Strength in Unity

Collaborative soils research for Central America

f_streng_in_unity.jpg (9389 bytes)In search of a whole that is greater than the sum of its parts, international and national organizations engaged in soils research have made a sizable investment during recent years in building collaborative networks, often with impressive results.

One product of these efforts is the Integrated Soil Management (MIS) Consortium for Central America. This is one of four R&D consortia sponsored by the CGIAR’s Soil, Water, and Nutrient Management (SWNM) Program, which CIAT coordinates. MIS aims to improve the livelihoods of small farmers by developing improved practices for integrated management of fragile soils. Members work toward this end through joint research projects at shared "reference" sites—two in Honduras and two in Nicaragua.

Barriers That Permit Progress

Making soil conservation pay in Colombia

f_noti_barreras.jpg (7776 bytes)A lot of people would like to have my land," says José Balcué, a weatherbeaten, 68-year-old farmer. "But I’m not going to sell it!"

His farm, "La Camelia," is perched on a steep slope leading down to the Cabuyal River in the community of Caldono in Colombia’s Cauca Department. Despite its difficult topography, Don José is proud of the farm, because it shows no signs of soil erosion, its soils require no chemical fertilizers, and, by maintaining a constant output of diverse agricultural products over the years, it has enabled him to raise his six children.
