In recent years, wild boars (Sus scrofa) have caused growing damage to farm crops in a hilly and mountainous area of the Tohoku region. In particular, in designated evacuation zones following the accident at the Fukushima Dai-ichi nuclear power plant, there are growing concerns about the expanding range of wild boars and the resulting degradation of farmland.

The combination of rice and fish production into one system is considered to be an efficient means of agricultural land use for small-scale farmers. In some of these so-called rice-fish systems rice and fish are grown in the same field, at the same time; in other systems they are grown in the same field, but in rotation. Rice-fish farmers pay most attention to the maximization of the rice yield. This is a logical choice because the rice field is not the most ideal environment for fish production as the rice crop shades the field floodwater, thus hampering aquatic primary production.

Forestry plantations should be regarded as an alternative sustainable land-use system in degraded savannah areas. They contribute to the maintenance of productive processes in degraded soils that are of economic importance for local inhabitants; in addition, in the ecological sense, timber and non-timber products from planted forests reduce the exploitation pressure on native forests. Eucalyptus plantations on degraded savannahs in the northern Brazilian Amazon may help to reduce exploitation pressure on native forests.

Nineteen microsatellite markers were used to fingerprint a set of 19 potato landraces from the island of La Palma (Canary Islands). These landraces represent relicts of early introductions from South America, although most are commonly cultivated by local farmers. The SSR primers detected 62 polymorphisms, 13 of which were present in all landraces. Several accession- and group-specific markers were detected. Jaccard similarity coefficients were estimated from the molecular data and UPGMA cluster analysis was performed. Some cultivars with related common names clustered together.
