Plant density and tiller cunts were done in several Sahelian rangelands in Mali, under a variety of soil, rainfall and grazing situations. Numeric models were developed to explain the dynamic relationship between grass tillering and herb density. Tests of application of these models to the plant ...

Improvements in agricultural land and labour productivity are needed to meet the growing food demand and reduce farmer poverty in sub-Saharan Africa. The objectives of this study were to (i) quantify variation in labour inputs, yield and labour productivity among rice fields; (ii) elicit factors ...

The preceding chapter has demonstrated at the macro-level the importance of agricultural and economic growth for the significant reduction in rural poverty in MSEA that has occurred in recent decades. In this chapter we aim to identify and explain the major trends and trajectories of rice-farming...


Cramb, R.A.Newby, Jonathan C.[Trajectories of rice-farming households in mainland Southeast Asia]Trajectories of rice-farming households in mainland Southeast Asia

For centuries, the populations of Mainland Southeast Asia (MSEA) have endured material poverty, particularly in rural areas and among subsistence-oriented, rice-farming households. In the 20th century in particular, the impact of colonialism, war, and collectivist regimes exacerbated the poverty ...

In the five countries of Mainland Southeast Asia (MSEA) that are the focus of this review, there is no questioning the importance of rice within the landscape, in the farming systems, in the diet, and even in cultural terms. Currently, an area of about 32 million ha is cultivated to rice each yea...
