Biogas Plants in Animal Husbandry

Biogas plants have become something of a permanent fixture in Technical Cooperation between
the Federal Republic of Germany and partners in developing countries. Dating back to 1977, the
first such projects were incorporated into cooperative efforts with Indian and Ethiopian
organizations. At about the same time, the first GTZ project dealing solely with the transfer of
biogas technology and the construction of biogas plants was launched in Cameroon.
In the meantime, GTZ has assisted in building and commissioning several hundred biogas plants in
Asia, Africa, South and Central America. While most of the systems, in question are on a small
scale intended to supply family farms with energy and organic fertilizer, some large-scale systems
with the capacity to generate more than 100 m³ of biogas daily have been installed on large stock
farms and agroindustrial estates.
In general, biogas technology is for rural areas. In addition to generating energy, biogas systems
help stimulate ecologically beneficial closed-loop systems in the agricultural sector while serving to
improve soil quality and promote progress in animal husbandry. Consequently, the promotion of
biogas technology is regarded as an integral part of technical cooperation in rural areas and, hence,
as a key sector of development cooperation on the part of the Federal Republic of Germany.

Biosaline Agriculture And Salinity Tolerance In Plants

This volume focuses on reclamation, management, and utilization of salt-affected soils, their sustainable use, and evaluation of plants inhabiting naturally occurring saline habitats. It is of interest to scientists and students as well as agricultural institutions and farmers to increase the awareness of salinity problems. The volume is supported by UNESCO Doha, Qatar, and has an international authorship.

Biosaline Agriculture And Salinity Tolerance In Plants

The availability of freshwater for agricultural use is declining in many areas of the world. This is the reason for the increasing use of lower quality or of saline water for crop production. Prolonged use of saline water severely affects the irrigated soils, which contributes to the global land degradation process and has direct impact on biomass production. For this reason, reduction of the spread of salinization, revitalization of salinized areas and introduction of salt tolerant high-yielding crops are important issues. The potential role of halophytes in the management of salinity problems of arid lands is investigated at length nowadays; some of these have produced promising forage crops. This volume focuses on reclamation, management, and utilization of salt-affected soils, their sustainable use, and evaluation of plants inhabiting naturally occurring saline habitats.
