| Water use efficiency for irrigated agriculture still remains low. This presents a risky trend in the near future due to diminishing water resources as well as rising population demanding increased food supplies. The objective of the study was to investigate pumped irrigation methods used by smallholder farmers in the arid and semi-arid land environments as well as assess the water use efficiency during crop production under usual farmer management. The study was carried out in Mitubiri location of Kakuzi division and Kithimani sub location of Yatta division, Kenya. Observational study during the field transect walks in the study sites identified methods of irrigation used by the smallholder farmers, water conveyance as well as application methods and... |

| An isolated pterosaurian caudal cervical (~ postcervical) vertebra was recovered from the Upper Cretaceous Lapurr sandstone ofWest Turkana, northwestern Kenya. The vertebral centrum is short, wide, and dorsoventrally compressed. Although the specimen is lightly built similar to most pterosaurs, it is here referred to Pterodactyloidea and tentatively to the Azhdarchidae in that it lacks pneumatic features on both the centrum and neural arch. This represents one of the few pterosaurs recovered from the entirety of Afro-Arabia, the first pterosaur recovered from the Cretaceous of East Africa, and, significantly, a specimen that was recovered from fluvial deposits rather than the near-shore marine setting typical of most pterosaur discoveries. |

| The heterogeneous nature of even small communities has been acknowledged, yet how such heterogeneity is reflected in local ecological knowledge (LEK) among groups of resource users in a community is poorly studied. This study examines the ecological knowledge held by fisher groups using differing gear and operating in different subsystems of a coastal seascape in south Kenya. Knowledge is compared to that of nonfishing groups and is analyzed with respect to the scales of ecological processes and disturbances affecting the ecosystem to identify mismatches of scale between local knowledge and ecological processes, as well as points of convergence upon which emerging scientific and local community information exchange can build and develop. Results reveal... |

| In studying indigenous climate knowledge, two approaches can be envisioned. In the first, traditional knowledge is a cultural built-in object; conceived as a whole, its relevance can be assessed by referring to other cultural, economic, or technical components at work within an indigenous society. In the second, the accuracy of indigenous climate knowledge is assessed with western science knowledge used as an external reference. However, assessing the accuracy of indigenous climate knowledge remains a largely untapped area. We aim to show how accurate the culturally built indigenous climate knowledge of extreme climatic events is, and how amenable it is to fuzzy logic. A retrospective survey was carried out individually and randomly among 195 Eastern... |

| Development and deployment of genetically engineered crops requires effective environmental and food safety assessment capacity. In-country expertise is needed to make locally appropriate decisions. In April 2007, biosafety and biotechnology scientists, regulators, educators, and communicators from Kenya, Tanzania, and Uganda, met to examine the status and needs of biosafety training and educational programs in East Africa. Workshop participants emphasized the importance of developing biosafety capacity within their countries and regionally. Key recommendations included identification of key biosafety curricular components for university students; collaboration among institutions and countries; development of informational materials for non-academic... |

| Micractaeon kakamegaensis Verdcourt, 1993 (type loc. Kenya, Kakamega Forest), is a synonym of Pseudopeas koptawelilense Germain, 1934 (type loc. Kenya, Mt. Elgon); the proper name is therefore Micractaeon koptawelilensis (Germain, 1934). New anatomical data are supplied, more or less confirming classification in the family Ferussaciidae. The shell is subject to some considerable variation in size, shape and sculpture. The species appears to be widely distributed in various types of forest in tropical Africa (Ghana, Cameroon, eastern and south-eastern Zaïre, Kenya, Malawi, and eastern Zambia); hypsometrical distribution is generally from c. 950 m to c. 2300 m, although in Ghana it has been collected at altitudes of between < 250 and c. 700 m. |

| This study aimed to describe the characteristics of villages and women’s households that might induce environmental awareness among fuel wood collecting women in one location of Kenyan dry land. Two probit models were constructed to examine which parameters were associated with two dependent variables, afforestation action and thermal efficient improved cooking oven. Participation in age of respondent, family size and group-activities had a significant effect on two dependent variables. However, age and family size indicated opposite relation on two independent variables. Moreover, it could be considered that one of important factor of improved cooking oven was economically affordability because of large property (i.e. to have cows and lands). On the other... |

| Port-Reitz Creek (04°04' S, 39° 39' E) is one of the two main tidal mangrove fringed creeks found in Mombasa Island. It experiences semi-diurnal pattern of two low and two high tides every 24 hour cycle. Six stations were strategically positioned along the length of the creek and sampled for heavy metal (cadmium, copper, iron and zinc) content during July 1998. A peak of Cu and Zn (87 and 235 µg/g dry weight respectively) was observed at Station 2, which borders a steel factory and fish-processing firm. A correlation matrix showed close distribution pattern between Zn and Cu (r = 0.67) and between Fe and Cd (r = 0.62). A peak for Cd (6 µg/g dry wt) was observed at Station 3. Fluvial input in the creek was a source of Cd, Cu, Fe and Zn. Cd and Zn were of... |
