Effects of land tenure systems on resource-use productivity and efficiency in Ghana’s rice industry

Reports & Research
ноября, 2014
Ghana

This study examines the effects of land tenure systems on resource-use productivity and efficiency in the Upper East region of Ghana with data drawn from the Ghana Agricultural Production Survey. A stochastic frontier model is employed to analyse resource-use productivity and efficiency of the rice farms. The study establishes that rice farms under the various land tenure systems are technically inefficient. Technical efficiency for the pooled sample was 61.80%.

The agricultural, environmental and socio-political repercussions of Brazil's land governance system

Peer-reviewed publication
декабря, 2013
Brazil

Although many contemporary studies of agriculture associate larger properties with higher relative productivity, this assumption has limited relevancy for the analysis of situations in which property owners profit more from large-scale property accumulation itself rather than any superiority in exploitation opportunities offered by increased size. In Brazil, the efficiency-of-scale paradigm has been used to criticize peasant agriculture as unproductive and hide contradictions deriving from land concentration.

The Effects of Biofuel Feedstock Production on Farmers’ Livelihoods in Ghana: The Case of Jatropha curcas

Peer-reviewed publication
декабря, 2013
Ghana

The widespread acquisition of land for large-scale/commercial production of biofuel crops in Ghana has raised concerns from civil society organizations, local communities and other parties, regarding the impact of these investments on local livelihoods. This paper assessed the effect of large-scale acquisition of land for production of Jatropha curcas on farmers’ livelihoods in Ghana. The study was conducted in 11 communities spanning the major agro-ecological zones and political divisions across Ghana.

Amazing maize in Malawi : input subsidies, factor productivity and land use intensification

Reports & Research
декабря, 2013
Malawi

The paper uses three years of household farm plot panel data (2006-2009), covering six districts in central and southern Malawi to assess factor productivity and farming system development under the input subsidy program. All farm plots of the households were measured with GPS. Maize production intensified in this period as maize area shares of the total farm size were reduced while input use intensity and yields increased. Yields of improved maize were significantly (+323 kg/ha) higher than for local maize.

Field-Level Measurements of Land Productivity and Program Slippage

Reports & Research
декабря, 2013
Norway

The importance of heterogenous land quality in determining slippage on corn production in North Carolina is quantitatively analyzed. Field-level analysis controls for the influence of land productivity from other factors to determine the significance of the land decisions on slippage. Results show that yield hikes from the diversion of low-quality land by farmers comprise a minor contribution to total increases in average yield.

Market imperfections and land productivity in the Ethiopian Highlands:

Reports & Research
мая, 2013
Canada
Ethiopia
Norway

This study analyzes how market imperfections affect land productivity in a degraded low-potential cereal- livestock economy in the Ethiopian highlands. A wide array of variables is used to control for land quality in the analysis. Results of three different selection models were compared with least squares models using the HC3 heteroskedasticity-consistent covariance matrix estimator. Market imperfections in labor and land markets were found to affect land productivity. Land productivity was positively correlated with household male and female labor force per unit of land.

Does land fragmentation affect land productivity? Empirical evidence from Bulgaria

Reports & Research
декабря, 2012
Bulgaria

Land fragmentation is considered a major obstacle to the efficient use of land and other agricultural resources in Bulgaria. This study is concerned with formally testing the relationship between fragmentation of land plots and land productivity in the country. Multiple regression analysis and agricultural data obtained from the 2003 Bulgaria Multi-topic Household Survey is employed for the purpose. Results of the study suggest that the level of current fragmentation is relatively low and not likely to adversely affect land productivity.

Distribution and Variation of Forests in China from 2001 to 2011: A Study Based on Remotely Sensed Data

Peer-reviewed publication
декабря, 2012
China

Forests are one of the most important components of the global biosphere and have critical influences on the Earth’s ecological balance. Regularly updated forest cover information is necessary for various forest management applications as well as climate modeling studies. However, map products are not widely updated at continental or national scales because the current land cover products have overly coarse spatial resolution or insufficiently large training data sets.

The Distributional Impact of Developed Countries’ Climate Change Policies on Senegal: A Macro-Micro CGE Application

Peer-reviewed publication
декабря, 2012
Senegal

In this paper, we present a distributional impact analysis of climate change policies envisaged or implemented to reduce greenhouse gas emissions in Senegal. We consider policies implemented in developed countries and their impact on a developing country. Moreover, we simulate the diminishing productivity of agricultural land as a potential result of climate change (CC) for Senegal. This country is exposed to the direct consequences of CC and is vulnerable to changes in world prices of energy, given its lack of substitution capacity.

UNCCD Impact Indicators Pilot Tracking Exercise: Results and Conclusions

Reports & Research
декабря, 2012
Global

This report presents results and conclusions from a Pilot exercise undertaken to assess the experience of
affected country Parties to the United Nations Convention to Combat Desertification (UNCCD) with
reporting on impact indicators under the Convention’s Performance Review and Assessment of the
Implementation System (PRAIS). The experiences and recommendations presented in this report should
be used to guide the 2012–2013 reporting and review process.
