Agriculture influences and shapes the world’s ecosystems, but not always in a positive way. More than 2.5 billion people are globally involved as stewards of land and water ecosystems that constitute the natural resource base for feeding the current and future world population. Yet, conventional agronomic interventions based on ‘hard’ agricultural engineering compromise various eco-services that are required for sustainable agricultural development.

The Restoration Opportunities Optimization Tool (ROOT) was developed out of a need to more efficiently and effectively communicate the importance of ecosystem services to decision makers.
IUCN’s collective experience working to increase ecological productivity and improve human well-being through forest landscape restoration (FLR) demonstrated that although stakeholders were interested in generating ecosystem services from proposed restoration activities, the many services and their interactions with each other were often too complicated to communicate clearly.

Land Use Policy Volume 99
Peer-reviewed publication
Colombia, South America, Central America
Much of the research on urbanization has focused on how rural populations move to cities for work opportunities. This paper takes a different perspective on the relations between rural populations and urbanization. The livelihoods of rural dwellers on the outskirts of the city of Bogotá in Colombia are increasingly affected by the expansion of urban activities and infrastructure. Therefore, urbanization takes place in the areas of residence of the rural populations; these people do not migrate to the city but, rather, the city migrates to them.

The factors influencing the size and shape of exptl. field plots (area of exptl. lot, soil types, trial objective, no. of replicates, and degree of accuracy and homogeneity of the exptl. material) for the execution of field expt. are discussed. The basic principles of the following different methods to determine plot size are described: max. curve method, method of Koch and Rigney, Hatheway's method, and the max. curve method using the multiple linear regression model. Some considerations are presented on the border effect and on plot size in bush and climbing bean trials.

Soil management in the Altillanura of Colombia’s Eastern Plains The strategies used for adequate soil management for the Altillanura (high plains with flat topography) of Colombia’s Eastern Plains are reviewed to establish modern, efficient, and sustainable livestock systems in this region. Advances in technology development within the technical and scientific cooperation agreement signed between Colombia’s Ministry of Agriculture and Rural Development (MADR) and CIAT, as well as those of the Center’s Soils Project and several national institutions co-partners in the agreement.

White mold, caused by the fungus Sclerotinia (Whetzelinia) sclerotiorum, is distributed worldwide and has more than 300 hosts. It infects flowers, cotyledons, seeds, leaves or injured plant tissue. The disease can be controlled by crop rotation, flooding, reduced seeding rates, application of chemical products in the middle of the flowering period, modifying plant architecture and the use of resistant var. Many soil microorganisms are associated with sclerotia and may cause them to degrade or fan to germinate. The symptoms and damage caused by the disease are illustrated in color.
