“…To elucidate the effect of projected changes to various stages of rice growth, we accumulated the above data set for the each growth stage of the rice crop following Wopereis et al . (), namely vegetative (from germination to panicle initiation), reproductive (from panicle initiation to flowering) and maturation phases (from flowering to maturity).…”

This study addresses the impact of projected changes to northeast monsoon on rice yield during rabi season (September–December) in Tamil Nadu by using a three‐step approach. First, coarse‐resolution global climate models that realistically capture the mean monsoon characteristics were selected. Second, lateral and boundary conditions taken from selected global models’ projections are employed to run a high‐resolution regional climate model. Third, climate variables from regional model being fed into panel data regression model. For different scenarios and for mid and end of century projections, in conjunction with projected rainfall, a comprehensive assessment is carried out to underscore the sensitivities of maximum and minimum temperatures under different stages of rice production, viz. vegetative, reproductive and maturity phases, and to the concept of growing degree days (GDD, cumulative heat effect). Irrespective of scenarios, in response to an increase in projected monsoon rainfall and surface temperature conditions, the regression model estimates an increase of rice yield of about 10–12% by mid‐century and 5–33% by the end of the century. In the regression model, the baseline coefficients were estimated from observed rainfall and temperature available from India Meteorological Department (IMD). The projected changes in rice yield, however, remain unchanged for baseline coefficients estimated from regional climate model outputs (forced by reanalysis products) rainfall and temperature. The robust results obtained here provide confidence to the findings.

“…Participatory learning and action research methods need to be used to introduce and experiment IRM options with farmers. This is especially true for the more diverse and complex rainfed lowland systems (Wopereis and Defoer, 2007). The research and agricultural extension systems need to be strengthened to diffuse IRM options to a larger number of farmers.…”

Integrated soil fertility management (ISFM) is generally accepted as the most relevant paradigm for soil fertility improvement in the tropics. Successes however are mainly reported at plot level, while real impact at farm level and beyond remains scattered. As a consequence, many Sub-Saharan African countries continue experiencing soil nutrient mining and insecure and insufficient agricultural production. Since technology-driven projects at the plot level failed to bring ISFM to scale, a different approach is needed. This paper describes a bottom-up approach developed in Burundi, the ''PIP approach''. It starts at farmer family level with the creation of an integrated farm plan (Plan Intégré de Paysan in French-PIP) and aims at wide-scale spreading of farmers' intrinsic motivation to invest in activities that make the household more resilient and profitable, while moving towards sustainable agricultural intensification based on concepts of ISFM. As such, and once firmly embedded in and supported by village or district plans, agriculture becomes a business rather than a default activity inherited by parents, and ISFM an intrinsic aspect of farm management. In this paper the PIP approach as currently being implemented in Burundi is explained and discussed, with special reference to soil fertility management and some preliminary promising results.
