    Climate Variability and Farm technology adoption decisions among smallholder farmers in Pangani River basin
    (IISTE, 2016) Moshi, Arbogast; Hella, Joseph; Isinika, Aida
    Climate change is currently a serious threat for agriculture development and food security in sub-Saharan Africa. With the Intergovernmental Panel on Climate Change (IPCC) climate outlook for the 21st century, the future of maize production in Tanzania remains under threat due to more intense and frequent droughts, and more erratic rainfall patterns. Effective adaptation to these ongoing changes in climatic condition is key to securing food production and livelihoods for millions of poor people. This paper analyzes factors that facilitate or impede the probability and level of adoption of sustainable farm technologies and farm households in response to climate shocks. A multivariate probit model was applied to the model the adoption decisions by farm households facing multiple farm technologies which can be adopted in various combinations. The analysis shows that both the probability and the level of decisions to adopt farm technologies influenced by rainfall and plot-level disturbances, household wealth, institutional factors, distance to the farm plot and input market. The results further show that there were complementarities between farm technologies which are not yet sufficiently exploited. In the light of these findings, government policies, and strategic investment plans should ensure the provision of improved farmer education to generate greater awareness about the multiple benefits of sustainable agricultural practices in the fight against climate change and variability.

    Options to increase adoption of lowland rice - legume technologies in Morogoro, Tanzania

    The main concern in agricultural research is to ensure that research products are adopted by farmers. However, the rate of adoption is low. Most research on adoption rates are post-ante. The values of such research can be added if factors for adoption are ex-ante identified and measures taken to increase adoption. This study was conducted in Morogoro, Tanzania to ex-ante identify socio-economic characteristics that influence adoption of Integrated Lowland Rice Legume Technologies (ILRLT). The ILRLT included integration of rice (SARO variety), legumes (cow pea) water management (irrigation, rainfed and majaruba bunds), tillage (conventional and minimum) and fertilizers (UREA, TSP and MOP). Data were collected through questionnaire interviews to 200 representative farmers and key informants. Descriptive statistics, Multi-Criteria Analysis and a two functions adoption model were used to assess the suitability of ILRLT and analyze the likelihood of farmers to adopt. Results indicated that important criteria for rice variety preference and hence adoption are high prices (7.8%), good taste (6.1%), early maturity (4.8%), disease (3.2%) and drought tolerance (17.4%). ILRLT scored more (26.40%) than farmer’s (17.97%) in fulfilling criteria for rice legume variety preferences. ILRLT have a chance of being adopted to the maximum rate of 89.7%. Adoption is likely to be more with farmers who depend on irrigation than those who depend on rainfed rice farming.
