The effect of agricultural intensification on ecosystem Services around Ihemi cluster
(Tanzania Journal of Forestry and Nature Conservation, 2021) Sirima, A; Kashaigili, J.J; Kamau, F.
As the world population continue to increase, the demand for food also increases which necessitate the need for agricultural intensification. Agricultural intensification affects large parts of terrestrial area, therefore, assessment of its contribution to the decrease of ecosystem services is critical for successful conservation in the future. A study was conducted in five districts of Iringa and Njombe Regions, part of Ihemi cluster, to assess the effects of agricultural intensification on ecosystem services. A total of 607 household surveys and 19 Focus Groups discussions were conducted. Descriptive and cross tabulation were used for quantitative analysis while content analysis was used for qualitative data. Findings reveal that there are several benefits communities get from the ecosystem that play a great role on their livelihood. Across all villages, firewood is preferred due to its affordability and availability. Other ecosystems goods such as traditional medicine and mushrooms are hardly available due to clearing of land for agricultural activities, as well as settlement expansion. Community activities, such as valley bottom farming was mentioned as a practice that jeopardize the long-term sustainability of ecosystem resources within the Cluster. Agricultural intensification by investors was also mentioned as a sources of ecosystem depletion. Sustainable agricultural intensification, if adopted, might be one among the solutions to serve the ecosystem around the cluster
Land fragmentation, agricultural productivity and implications for agricultural investments in the Southern Agricultural Growth Corridor of Tanzania (SAGCOT) region, Tanzania
(2017-02) Kadigi, R. M. J.; Kashaigili, J. J.; Sirima, A.; Kamau, F.; Sikira, A.; Mbungu, W.
There are polarized evidences of the impact of agricultural land fragmentation on land productivity. On the one hand there viewpoints which consider land fragmentation to harm agricultural productivity. On the other hand there are counter thoughts which view land fragmentation as a positive situation which allows farmers to cultivate many environmental zones, minimise production risk and optimise the schedule for cropping activities. We use the case of Ihemi cluster in the Southern Agricultural Growth Corridor of Tanzania (SAGCOT) to investigate the impact of land fragmentation on crop productivity. We furthermore discuss the nature and causes of land fragmentation in the SAGCOT region and its implication on the future structure of agricultural landholdings and welfare of smallholder farmers in the region. The results showed that the nature and level of fragmentation in the study area were the outcome of combined, rather than isolated influences of supply and demand driven factors. Overall, the results did not support the claim that fragmentation reduces land productivity. This then implies that land fragmentation should not always be considered as defective. There were evidences of increasing chunks of land owned by rich farmers and investors which increased the possibility for increased consolidation of agricultural land under large scale farming. However, the landholdings for smallholder farmers might become increasingly more fragmented as poor smallholder farmers continue selling their land holdings to rich farmers and investors. Releasing the SAGCOT region’s potential for agricultural development will require that smallholder farmers are helped to secure adequate and suitable land for farming, raise agricultural productivity, diversify their sources of income, and adopt good production practices. This requires setting up a strong base of investor - farmer synergies for inclusive agricultural growth.
