“…However, research development of high-yielding Jatropha varieties is still necessary to achieve the economic yield before they are implemented for a sustainable biofuel program as suggested by Kgathi et al (2017) for the Jatropha project in Bostwana. In addition, agronomic and socio-economic research of Jatropha should be fully understood before developing on a large scale which maybe offers risk (Mmopelwa et al, 2017 Improving yield and harvesting efficiency will increase economic performance in Jatropha (Van Eijck et al, 2012).The low seed yield in the first year is related to the low number of harvested capsules from June to December 2018. Jet-1 Agribun plants received 184.6 mm of rainfall in year I and 594.84 mm in year II until December 2019 (Figure 4).…”

Jet-1 Agribun is one of the Indonesian Jatropha new varieties suitable for rainfed areas with a high yield of dry seed and oil content. The field trial was conducted at Asembagus Experimental Station in Situbondo, East Java from February to December 2019 and aimed to observe the potential of Jatropha Jet-1 Agribun under rainfed conditions. Observation on seed yield and growth components of Jatropha plantation was also made in two and three years old Jet-1 Agribun. Results of the observation showed that Jet-1 Agribun in the first year produced seed 471.8 kg/ha. A two-year-old plant produced a dry seed of 3,958.7 kg/ha. Three-year-old plants after pruning produced dry seed 910.95 kg/ha and 916.04 kg/ha at 1 m x 1 m and 2 m x 2 m, respectively, indicating that wider spacing is more allowable for cropping with food crops until the canopy closes. Development of Jatropha should be integrated with food crops or other crops through intercropping systems, by using the land around the plants until the canopy closes.

“…This implies that the cultivation of Jatropha is not economically feasible to the extent of improving food security and livelihood of locals. Studies revealed that the production of Jatropha is not economically attractive and it negatively affects food security and the livelihood of rural people in Ghana (Acheampong and Campion 2014) and Botswana (Mmopelwa et al 2017).…”

Background In recent years, there have been global concerns regarding the continuous use of non-renewable fossil fuels as the major source of energy. The utilization of non-renewable fossil fuels has negative effects on global warming and climate change. So far, efforts to curb the situations have tended to focus on promoting alternative renewable energy sources such as the use of biofuels to cut down emissions of green house gases. However, the production of biofuel crops has become an issue of concern in many developing countries. This is because the expansion of land for biofuel crops cultivation is directly linked to food security and the livelihoods of rural communities. The present study, therefore, aimed to evaluate the contribution of non-food biofuel crops (Jatropha curcas) to the improvement of rural household livelihoods and its impacts on food security. A survey was conducted in 84 households in Arumeru and Siha Districts in the northern Tanzania.Results The results revealed that the introduction of Jatropha as a cash crop had no significant impact on the rural livelihoods since the five capitals of the framework have not optimally been utilised despite their presence. It was further revealed that Jatropha cultivation has not affected food security. This is contrary to fears that biofuels could generally have a negative impact on food security especially in developing countries. The crop had not been regarded as a cash crop or a biofuel; thus, a very little percentage of land owned by the respondents had been allocated for its cultivation. The importance of Jatropha in the study area has yet to be recognised and given the special attention it requires.Conclusions It can be concluded that, the current situation does not indicate any significant impact of Jatropha cultivation on food security. However, it has little contribution to livelihood improvement of the smallholder farmers. Therefore, research on the improvement of Jatropha productivity under optimum conditions and pricing should be further undertaken in different areas of the country.
