in land holdings have necessitated an intensification of agricultural production throughout the region, including also in Onjiko and Thurdibouro, where shifting cultivation of diversified crops has been replaced by predominately sedentary mono-cropping. In Kunsugu and Kisumwa, formerly areas with heavy livestock-rearing, the number of livestock per family has dropped significantly and reliance on food crops is now higher than in the past (field data 2008). These shifts have also contributed to the spread of invasive weeds and a further loss of crop productivity (Smucker and Wisner 2008). To maintain Vorinostat supplier food production, farmers have responded to these negative feedbacks by increasing

labor activities, such as weeding, CRT0066101 ic50 during intense periods of the growing season. But it is not easy for everyone to obtain the labor needed, as Jane explains: Manpower is lacking now. Only parts of the farmland are tended in the way I want and thus yields are not as high as they could be (Jane, 29 October 2008, Kenya). Moreover, Z-DEVD-FMK mouse strenuous labor requires well-nourished and healthy individuals. Our study indicates that the majority of people are neither. In fact, the population is sensitive to several vector- and water-borne diseases, many with clear linkages to climatic conditions, including, but not limited to, malaria, typhoid, dengue fever, schistosomiasis, cholera and trachoma (Focus groups 2009). [In the past] we could fetch water from the river and drink Oxymatrine it. There were no diseases like dysentery, cholera and malaria like today (Wilfrieda, 27 October 2008, Kenya). Being the worst and most common

disease, malaria affects nearly every family in any given year (Table 3), thereby making it endemic and the leading cause of mortality and morbidity in both children and adults in the basin (Wandiga et al. 2006). Farmers also indicate a rise in the incidence of the disease and its presence on a year round basis: Table 3 Climate-related diseases afflicting households during 2006   Onjiko, KE (n = 50) Thurdiburo, KE (n = 50) Kunsugu, TZ (n = 50) Kisumwa,TZ (n = 50) Malaria 41 43 49 48 Dengue fever 0 0 25 23 Diarrhoea 3 1 4 10 Source: Baseline survey of a total of 600 HH conducted in September–October 2007 Nowadays malaria is a bigger problem, making people sick more often (Neema, 17 November 2008, Tanzania) According to Githeko (2009), this rise may be linked to increasing rainfall variability, which contributes to the spread of mosquito habitats over time and space. Cholera is also endemic to the LVB but the frequency and severity of episodes have increased in the last 20 years, explained in part by climate changes (Wandiga 2006).
