Drylands cover over 40% of the earth's surface and support over 2 billion people, globally (Millennium Ecosystem Assessment, 2005). In East Africa alone, over 250 million people depend on drylands for their livelihoods (De Leeuw et al., 2014) and in Kenya, 70% of the total land area is classiﬁed as arid- and semi-arid (Batjes, 2004). Over the last several decades, an increasing and more sedentary human population has resulted in more pressure on these lands, and an expansion of agricultural production into marginal dryland areas that were traditionally rangelands.

The diversity of nematode destroying fungi in Taita Taveta, Wundanyi division, Coast
Province, Kenya, was investigated between May 2006 and December 2007 aiming at harnessing
their potential in the biological control of plant parasitic nematodes in the area.
Given that the intensity of land cultivation is continually increasing in the study area, it is
prudent to document the status of the nematode destroying fungi before the remaining
forest habitats are ultimately disrupted. Soil samples were collected from forest, maize/

Establishment of seasonal grazing enclosures has become an important rangeland rehabilitation strategy in semi-arid regions. This study assessed the impact of enclosure age and enclosure management on the vegetation composition in the Njemps Flats range unit, Lake Baringo Basin (Kenya). Six communal enclosures (13–23 years since establishment) and six private enclosures (3–17 years since establishment) were selected.

The Kenya Government has over a number of years pursued policies geared towards the promotion of secondary towns. Included in this strategy is the achievement of an orderly and coordinated urban land development. However, experience from these towns indicates that, planned land development has encountered a lot of bottlenecks particularly in relation to the institution of private ownership of land. This paper traces the land tenure systems that have existed in the Kenya’s secondary towns.

Estimating the potential land resources suitable for irrigation and evaluating the possible impact of climate change on land suitability is essential for planning a sustainable agricultural system. This study applied a GIS-based Multi-Criteria Evaluation (MCE) technique to evaluate the suitability of land for irrigation in Ghana for a baseline period (1990 to 2010) and future time horizons 2050s (2041 to 2060) and 2070s (2061 to 2080).

Low adoption of sustainable intensification technologies hinders achievement of their potential impacts on increasing agricultural productivity. Proper targeting of locations to scale-out particular technologies is a key determinant of the rate of adoption. Targeting locations with similar biophysical and socio-economic characteristics significantly increases the probability of adoption. Areas with similar biophysical and socio-economic characteristics are referred to as recommendation domains (RDs).

Sapelli (Entandrophragma cylindricum) and tali (Erythrophleum suaveolens) are among the most important timber
species harvested from Congo Basin forests. They also host edible caterpillars, Imbrasia oyemensis and Cirina
forda, respectively, which are important to the nutrition and income of rural and urban populations. This study
evaluated the density of these tree species within a 10 km radius around each of 4 villages and in the 2012
annual cutting areas of two timber concessions in the region of Kisangani (DRC). Sapelli and tali trees

Innovations to improve staple crop germplasm can reduce poverty and otherwise improve farmer livelihoods through complex and multiple pathways. This paper reviews the evidence for one prominent pathway—through increased incomes (in cash and kind) for poor farmers who adopt the technology.

The promotion of land, soil and water conservation measures has been a widespread development in sub-Saharan Africa in a bid to tackle degradation and improve productivity. As a result, several governments have launched various campaigns on soil, land and water conservation measures. The aim of this study is to determine some of the factors that influence farmers’ awareness (knowledge) and adoption of land, soil and water conservation practices. Data for this study was collected from 312 households using a questionnaire survey in the Chinyanja Triangle of Southern Africa.
