In Zambia, like in other colonies, the British introduced a distinction between ”crown land” and ”native reserve land”. While in the latter land management and all the natural resources going with it, was left to ”native authorities” according to the principle of indirect rule, the former was administered in keeping with British regulations. Areas which lend to commercial farming, sites of copp...
1.Environmental changes may not always result in rapid changes in species distributions, abundances or diversity. In order to estimate the effects of, for example, land-use changes caused by agri-environment schemes (AES) on biodiversity and ecosystem services, information on the time-lag between the application of the scheme and the responses of organisms is essential.2.We examined the effects...
agricultural droughts are droughts that affect the crop production or the ecology of a region. ravar city that is located in margin of desert and the north of kerman province is one of these areas. due to the existence of enough underground water that entrance to desert and high evaporation to improving agricultural and cultivar activities, it needed to study the construction of underground dam...
This paper analyses the relationship between net farm incomes and market values of cane land within the South African sugar industry. A comparison is drawn between market values represented by actual sales, and productive land values, which relate more specifically to net farm incomes. The aim of the paper is therefore to estimate the degree of correlation between net farm incomes and land mark...
Land suitability analysis, commonly known as land evaluation, is considered an interface between land resourcesurvey and land use planning and management. Land evaluation be carried out to estimate the suitability of land fora specific use such as arable farming or irrigated agriculture. There are several established techniques for generatingland suitability evaluation. This research was carrie...
A and how the response of management affects them are considered. The information collected in a soil survey helps in the development of land-use plans and evaluates and predicts the effects of land use on the environment. Soil surveys were first authorized in the United States in 1896. Although extensive writings on husbandry by L.J.M. Columella were published in the first century A.D., practi...
Traditional smallholder farming systems dominate the savanna range countries of sub-Saharan Africa and provide the foundation for the region’s food security. Despite continued expansion of smallholder farming into the surrounding savanna landscapes, food insecurity in the region persists. Central to the monitoring of food security in these countries, and to understanding the processes behind it...
This paper examines the role that land rights play in the decision to either cultivate or lease a given plot. Using data from 2,874 farming households collected in 1997 in rural Thailand, we find that in villages adjacent to forest reserves, where the is a risk of expropriation, plots that are leased are more likely to be titled than those that are self cultivated. In other areas, however, land...
1,160 words) Section I challenges Nobel laureate Schultz’s assertions: (1) small farmers are rational; (2) low income countries saddled with traditional agriculture have not the problem of many farmers leaving agriculture for nonfarm jobs; (3) part-time farming can be efficient; (4) economies of scale do not exist in agriculture; and (5) investment in human capital counts much more than institu...
A key part of the strategy to manage the problems of flooding and sedimentation of the lower Yellow River in China is the control of soil erosion on the loess plateau. Land use practices are assumed to be the root cause of the high sediment yield and therefore able to be controlled. An analysis of the geomorphology of the loess plateau region shows that there are natural causes of high sediment...
