Climate change has resulted in increased vulnerability of smallholder farmers in marginal areas of Zimbabwe where there is limited capacity to adapt to changing climate. One approach that has been used to adapt to changing climate is in-field water harvesting for improved crop yields in the semi- arid regions of Zimbabwe. This review analyses the history of soil and water conservation in Zimbab...

Quantitative methods of spatial conservation prioritization have traditionally been applied to issues in conservation biology and reserve design, though their use in other types of natural resource management is growing. The utility maximization problem is one form of a covering problem where multiple criteria can represent the expected social benefits of conservation action. This approach allo...

Many conservation programs under the 2002 Farm Act address resource concerns such as water quality and aquatic communities in streams. Analyzing two such programs, simulated changes in agricultural practices decreased field-edge sediment losses by 25S31% in two geophysically distinct Minnesota watersheds. However, while in-stream sediment concentrations and lethal fisheries events decreased sig...

Decline in aquatic resource stocks, occurs for various reasons. Although regulations and measures have proven useful, they have failed to inhibit effectively the stock reduction trends. Iranian Fisheries Organization has carried out a great deal of investments and efforts concerning the enhancement of the Caspian Sea resource stocks through the restrictive regulations, and reproduction and rele...

While invasive plant species primarily occur in disturbed, high-resource environments, many species have invaded ecosystems characterized by low nutrient, water, and light availability. Species adapted to low-resource systems often display traits associated with resource conservation, such as slow growth, high tissue longevity, and resource-use efficiency. This contrasts with our general unders...

The lack of concrete instances in which conservation and development have been successfully merged has strengthened arguments for strict exclusionist conservation policies. Research has focused more on social cooperation and conflict of different management regimes and less on how these factors actually affect the natural environments they seek to conserve. Consequently, it is still unknown whi...

Current approaches to conservation planning have an established and successful track record. However, as our knowledge of resource sciences and goals for conservation expand, review and improvement of planning protocols could help improve conservation effectiveness, even though we may be satisfied with the status quo. This is easy to suggest, but we do not readily know how and when standard pla...

Despite their ambiguous historical record, conservation/development interventions the world over have remained a popular environmental governance tool. One of the latest global ‘trends’ are interventions to establish so-called ‘Transfrontier Conservation Areas’ (TFCAs): large contiguous spaces that are principally aimed at conserving biological diversity across national boundaries. In line with...
