摘要

基于确定的挑战和提出的方法,这篇论文构建了一个在坦桑尼亚雨水灌溉的低地地区提高水稻产量的案例[1]。拟议的倡议旨在作为发展合作领域的一项行动。尽管其性质复杂,但该倡议旨在加强雨养地区现有的水稻生产系统,从而提高合适水稻种子的可用性,并采用水稻集约化[1]系统中的元素,作为主要的农艺组成部分,应得到各自研究的支持。需要考虑的其他因素是这些雨育地区的土地和水的管理,这些地区季节性地用于水稻生产,而一年中的其他时间则保持休耕状态,以及生产系统的经济,这在目前是至关重要的,可能仍然是集约化的绊脚石,这也是由于灌溉地区更具竞争力的当地生产和廉价进口的威胁。

Can System of Rice Intensification Boost Smallholders’ Rice Production in Rainfed, Lowland Areas of Tanzania?
Based on challenges identified and approaches proposed, the paper builds a case for boosting rice production in rain[1]fed lowland areas of Tanzania. The proposed initiative is designed as an action in the field of development cooperation. Despite its complex nature, the initiative aims at an intensification of the prevailing rice production system in rainfed areas, whereby improving the availability of suitable rice seeds and adopting elements from systems of rice intensifica[1]tion (SRI) are proposed as the main agronomic components, which shall be supported by respective research. Further elements to be considered are the management of land and water in these rainfed areas, which are seasonally used for rice production, while the rest of the year they remain fallow, as well as the economics of the production system, which at present is critical and may remain a stumbling block for intensification, also due to the threat from more competitive local production in irrigated areas and cheap imports.
