Groundwater provides nearly 100 % of the water supplies in some districts of Sri Lanka and is a major source of domestic water in all other districts. However, the resource remains largely neglected and invisible to society and policymakers. Groundwater offers the advantage of being a more reliab...

Potential rotation crops for replacement of natural soil regeneration in tropical agriculture were grown in nematode infested soil following Celosia argeniea. The aggregate nematode population mean was one-third the preplant mean after six months. Meloidogyne incognita juvenile soil populations w...

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...

The abundance and diversity of soil mites was monitored along a gradient of land use types (LUTs) during the wet seasons in soils of Taita Taveta, Kenya. Sampling of mites from soils was carried out in eight LUTs which included maize-based system (Zea mays), coffee (Coffea Arabica), horticulture,...

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 ...

A major strategy towards addressing soil fertility depletion is the conservation and sustainable use of rhizobia that are able to fix nitrogen in the soil in association with legumes. The study assessed abundance and diversity of legume nodulating rhizobia (LNB) in soils collected from six differ...

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...
