Will afforestation in temperate zones warm the Earth?
For decades, forest researchers have known that planting trees on cropland or pastures (that is, afforestation) can lower the surface albedo and that landscapes with low albedo absorb more solar radiation than more reflective surfaces. Consequently, afforestation will typically darken the Earth’s surface (when compared to grasslands or deserts). In spite of this knowledge, many believe that afforestation will cool...

Effect of mulching and amount of water on the yield of tomato under drip irrigation
The main challenge confronting both rain fed and irrigated agriculture is to improve WUE and sustainable water use for agriculture. An experiment was conducted to evaluate the effect of mulch and amount of water on the yield of tomato under drip irrigation system and to assess the potential of deficit irrigation to improve the economic efficiency of tomato production at Adet Agricultural Research Center, horticultural...

Production, processing and marketing of ginger in Southern Ethiopia
The cultivation of ginger was started in Ethiopia during 13th century when Arabs introduced it from India to east Africa (Janson, 1981). In Ethiopia it is limited mostly in the wetter regions of Southern Nations, Nationalities and Peoples Regional State (SNNPRS) and some parts of western Oromia. Most of the commercial production is practiced in SNNPRS by farmers within Kambata-Tambaro, Wolaita and Hadiya zones. Despite...

An evaluation of successful reclamation of bauxite residue through afforestation activities in south India
The present article is based on the results of a pilot project implemented to improve the physico chemical characteristics of bauxite residue (red mud) in order to make it suitable for rehabilitation through afforestation activities. Prior to interventions, extensive experimentation on various reclamation trials involving combinations of soil amenders along with bacteria and mycorrhizae and selection of suitable tree...

Development of a low-cost tensiometer driven irrigation control unit and evaluation of its suitability for irrigation of lychee trees in the uplands of Northern Thailand in a participatory approach
In upland areas of Northern Thailand, lychee (Litchi chinensis, Sonn.) is one of the predominant fruit crops. Fruit development takes place during the dry season (January until June). Therefore, high lychee yields can only be obtained under irrigation. As water is an increasingly scarce resource in the hillsides, strategies for more efficient water use are fundamental for a sustainable increase in agricultural...
