The paper gives an overview of the directions and results of research carried out in geodesy and land management at the Latvia University of Agriculture from the year 1939, when the Surveying Department (later the Department of Geodesy) was established, up to the present day. Since the beginnings of the Department, researches in geodesy have been associated with problems of precise levelling: vertical movements of the earth crust, deformation of buildings and structures, as well as accuracy evaluation of geodetic instruments.

The aim of the research is to analyse the landscape structure changes from the end of the Soviet times in 1974–1986 until 2005 when market economy existed in Lithuania. The changes of landscape structure were observed in 100 sample areas (squares) each of them having 2.5 km2 area and distributed in different landscape types. The changes in sample areas (squares) with determination of land cover structure transformations were observed using topographic photos and ortophoto images at a scale 1:10 000.

This paper examines the case of a Nordic appropriation of land through a lease agreement with chiefs in southern Ghana, initially for biofuel production and then for large-scale, mechanized food production.The production shift triggered resistance over loss of land and environmental impact, and threatened to destabilize the project.This enticed the company to innovate through improving cooperation and offering compensation to individuals who lost land.

Asian countries have witnessed a sharp increase in real wage as a result of rapid economic growth and structural transformation in recent years. Using a country level panel data from 1980 to 2010, this paper examines the effects of real wage increase on Asian agriculture that traditionally used family labor intensively on small farms. The empirical evidence supports our hypothesis that an increase in real wages, along with absorptions of labor into nonagricultural sectors, has been inducing the substitution of labor by machines in agriculture.

With renewed interest in technical change and productivity growth in the African agricultural sector, interest is growing in the lessons of Asia’s Green Revolution and in the implementation of input promotion and subsidies to promote agricultural growth. While there are several valid reasons for seeking a model for African agricultural productivity growth from the Asian Green Revolution, the abundance of natural resources in Africa compared to Asia means that the Asian lessons might have limited application across Africa.

In 2011, the International Food Policy Research Institute (IFPRI) collected data for the final round of a panel survey to
evaluate how the resettlement project affected the food security of program participants in the long term. Although
programs like the CBRLDP appear in other African countries, few quantitative evaluations measure the short- or longterm
impact of resettlement policies. However, great lessons can be learned from ongoing research on this matter in
terms of the roles of land reform and migration in improving food security in sub-Saharan Africa.

The Government of Ghana (GoG) since 2007 has been providing subsidized agricultural machines to individual farmers and private enterprises established as specialized Agricultural Mechanization Services Enterprise Centers (AMSECs) to offer tractor-hire services to small-scale farmers across the country. Current demand in the country is primarily focused on land preparation services, especially plowing. This paper assesses whether AMSEC enterprises are a viable business model attractive to private investors.

Agriculture in African South of the Sahara (SSA) can be transformed if the right public support is provided at the initial stage, and it can sustain itself once the enabling environment is put in place. Successes are also specific to the location of projects. In Ghana, interesting insights are obtained from the successful Kpong Irrigation Project (KIP), contrasted with other major irrigation projects in the country.
