This chapter discusses the giving up of fallows and indigenous swiddens in times of global land grabbing in Cambodia. The Bunong of Bousra commune have been forced by tenure insecurity and increasing land scarcity to give up fallowing their land- an essential part of the swidden cultivation that...

This chapter puts into perspective some of the environmental conditions that horticultural species experience when grown within the tropics, from the lowlands to the highlands. It describes constraints of plant growth, especially that of cultivated horticultural species, by low temperature at high...

In order to determine the relative productivity of 16 promising forage legumes (12 species, 8 genera) in two major environments of central Belize (a neutral heavy cracking clay on an upper river terrace, and an acid waterlogged sandy loam on the Low Pine Ridge coastal deposits), trials with three...

This study was conducted to evaluate how land-use changes affect the distribution of SOC within a complex tropical landscape through the processes of erosion and sedimentation. The objectives were: (i) to estimate the present SOC storage at a landscape scale using predictors such as slope,...

This chapter deals with climate change effects in the Mediterranean littoral of Morocco, which is one of the most vulnerable countries within the Mediterranean region, especially the low-lying areas located in the eastern, i.e., Nador and Saidia areas, and western parts, i.e., Tangier and Tetouan...

This chapter describes the general climatic requirements of banana (Musa), showing that banana is primarily a crop of the humid tropical lowlands characterized by less than 10° latitude, less than 100 m altitude, not less than 19°C mean minimum temperature and more than 100 mm rain every month....

This paper describes the transfer by water of sediment from the land into watercourses in England and Wales. The sediment yields in catchments and how those may have changed in the recent past and the reasons behind those changes are discussed. The origin of sediment from lowland arable landscapes...

Data on suspended sediment transport and loads during rainfall floods and snowmelt-rainfall events in Zagożdżonka watershed, Poland, were analysed. The particle size composition of the material transported in the lowland river was evaluated based on a low-angle laser light scattering technique....

This chapter concentrates on the potential effects of transgenic cotton on the soil ecosystem of three major cotton growing areas in Vietnam: the coastal lowlands region, the central highlands (eastern and western Truong Son Mountain Range) and the south-eastern region. Soils in these three regions ...

A study was conducted to compare the estimates of seed dispersal by the woolly monkeys (Lagothrix lagotricha) with seed trap data and direct observations on fruiting trees to determine the proportion of seeds in the community dispersed by woolly monkeys. The study site is located in a tropical...
