    Kenya, Philippines

    This paper analyzes the adoption behavior of smallholder farmers using comparable plot-level duration data for Kenya and The Philippines. We find that adoption behavior is strongly linked to the process of land ownership transfer. This relationship is found both for data from Kenya and The Philippines and is robust to the inclusion of observed and unobserved village, household, plot, and time factors.

    Kenya

    In the Tana River Basin in Kenya, six Regional Circulation Models (RCMs) simulating two Representative Concentration Pathways (RCPs) (i.e., 4.5 and 8.5) were used as input to the Soil and Water Assessment Tool (SWAT) model to determine the possible implications for the hydrology and water resources of the basin. Four hydrological characteristics – water yield, groundwater recharge, base flow and flow regulation – were determined and mapped throughout the basin for three 30-year time periods: 2020–2049, 2040–2069 and 2070–2099. Results were compared with a baseline period, 1983–2011.

    Parasitic nematodes, especially
    Haemonchus contortus,
    are among the most common and
    economically important causes of infectious
    diseases of sheep and goats owned by
    pastoralists and small holder farm
    ers in East Africa. In Kenya, control of these infections
    mainly relies on the use of anthelmintic dr
    ugs. However, ethnoveteri
    nary medicine (EVM)
    preparations are widely used by pastoralists
    and small holder farmers (SHF) for treatment
    of their livestock agains

    Food security entails having sufficient, safe, and nutritious food to meet dietary needs. The need to optimise nitrogen (N) use for nutrition security while minimising environmental risks in sub-Saharan Africa (SSA) is overdue. Challenges related to managing N use in SSA can be associated with both insufficient use and excessive loss, and thus the continent must address the ‘too little’ and ‘too much’ paradox. Too little N is used in food production (80% of countries have N deficiencies), which has led to chronic food insecurity and malnutrition.

    The desire to overcome fragmented management of the natural ecosystems on which human beings depend has contributed to a growing interest in landscape approaches and to deeper questions about landscape governance systems. We assessed the emergent governance system that corresponds to the Mt. Marsabit landscape ecosystem in northern Kenya, applying a framework that includes 17 different indicators.

    African tropical montane forests are facing fast and dynamic changes in land use. However, the impacts of these changes on stream water quality are understudied. This paper aims at assessing the effect of land use and physical catchment characteristics on stream water concentrations of dissolved organic carbon (DOC), total dissolved nitrogen (TDN), nitrate (NO3-N) and dissolved organic nitrogen (DON) in the Mau Forest, the largest tropical montane forest in Kenya.

    Recent developments in Environmental Flow (E-flow) frameworks advocate holistic, regional scale, probabilistic E-flow assessments that consider flow and non-flow drivers of change in socio-ecological context as best practice. Regional Scale ecological risk assessments of multiple sources, stressors and diverse ecosystems that address multiple social and ecological endpoints, have been undertaken internationally at different spatial scales using the relative-risk model since the mid 1990's.
