(African foxtail grass)and Eragrostis superba Peyr (Maasai love grass) are important perennial rangeland grasses in Kenya. They provide an important source of forage for domestic livestock and wild ungulates. These grasses have been used extensively to rehabilitate denuded patches in semi-arid environment of Kenya. This study investigated the dry matter yields and hydrological properties of the three grasses under simulated rainfall at three phenological stages; early growth, elongation and reproduction. Laboratory seed viability tests were also done. Hydrological properties of the three grasses were estimated using a Kamphorst rainfall simulator. Results showed that there was a significant difference (p > 0.05) in dry matter yields and soil hydrological properties at the different grass phenological stages. Generally, all the three grasses improved the soil hydrological properties with an increase in grass stubble height...

However, the idea was borne earlier in the year from discussions originating from New Zealand scientists and negotiators at other climate change conferences. With imperiled climate change negotiations of the United Nations Framework on Climate Change Convention (UNFCCC) occurring earlier in the year and culminating in Copenhagen, an agreement was signed by government ministers of 21 countries to form the GRA and create a positive step forward for the agricultural sector, which previously was left without much voice in the UNFCCC negotiations. The 21 countries agreeing to participate in the GRA were Australia, Canada, Columbia, Chile, Denmark, France, Germany, Ghana, India, Ireland, Japan, Malaysia, Netherlands, New Zealand, Spain, Sweden, Switzerland, United Kingdom, United States, Uruguay, and Vietnam. The logo of the GRA is shown in Fig. 3.1.
