Mexico, Costa Rica, and Ecuador have substantial experience with implementing payments for ecosystem services (PES) and conservation incentive programs. Yet, many aspects of their experiences remain poorly understood and will require special attention in any new or expanded use of these types of incentives.
There is little empirical evidence concerning the effects of intellectual property rights (IPR) on a technologically advanced developing country. Complete enumeration of the Mexican maize breeding industry showed that, contrary to the hypothesis that IPR would provide, in a technologically advanced developing country, incentives for R&D and innovation, IPR play no role for the industry in general, but that they are important for certain breeders' categories. The paper presents the theory on IPR and a short background on the Mexican maize breeding industry.
Agricultural nitrogen is a major contributor to Gulf of Mexico hypoxia, and research has shown that agricultural subsurface tile drainage is a major carrier of nitrogen from croplands to streams and rivers. This study compares the results of abating nitrogen under a retired-land minimization policy with those of a new revenue-maximizing policy, paying particular attention to the role of tile-drained land.
Plant invasions and their impact on land use pose difficult research questions, due to the complex relationships between the ecological nature of the invasion and the human responses to the invasion. This paper focuses on the linkages between an invasion of bracken fern and land use decisions in an agricultural frontier in southern Mexico. Agriculture in this region is practiced on an extensive basis, using traditional slash-and-burn techniques of temporary cultivation and continuous rotation through forest fallow.
Land titles can increase agricultural productivity by increasing access to collateralized credit. However, increased credit use depends on the assumption that farmers face asset-based credit rationing. This assumption is tested using data from Mexico's voluntary land titling program. The results do not support the existence of widespread credit rationing.
This paper provides a theoretical framework to analyse land quality and labour allocation decisions by poor rural households in the context of increased population densities in slash-and-burn (shifting cultivation) agro-ecosystems. A bio-economic optimal control model is presented and its results calibrated with data from two farming communities from Yucatan (Mexico). The ecological-economic model restates the validity of the neo-Malthusian 'Population Pressure Hypothesis' (PPH) as a major factor of land degradation.
Agricultural nitrogen losses are the major contributor to nitrogen loads in the Mississippi River, and consequently, to the existence of a hypoxic, or dead, zone in the Gulf of Mexico. Focusing on two small agricultural watersheds in southeast Minnesota, simulation results from the Agricultural Drainage And Pesticide Management (ADAPT) model were combined with a linear-optimization model to evaluate the environmental and economic impact of alternative land-use policies for reducing nitrogen losses.
Land and land reform cover a great range, both in terms of the geographical and development status of the countries considered, and of the variety of perspectives on the issues. The articles in this issue of Land Reform, Land Resettlement and Cooperatives reflect this breadth in a variety of ways. The articles range geographically from the paper addressing land and agrarian reform in Colombia, by Professor Darío Fajardo, to a consideration of the land reforms currently under way in Scotland, by Douglas Macmillan, Ken Thomson and Bill Slee.
Land Tenure Working Paper 18. Presents the main themes that characterize the governance in land tenure and analyses the aspects related to the evolution of agricultural policy issues in various Central American countries. It also offers some examples and lessons learned from new models of land administration and land access mechanisms that Central American governments and International Cooperation have fostered over the past fifteen years in the Region.
