Sharecropping theory generally does not take into account land fertility. We develop a repeated Principal-Agent model under moral hazard where the Principal delegates the use and maintenance of a productive asset. In a multitask framework, we characterize the optimal spot contract focusing on...

There is a renewed interest in whether land reforms can contribute to market development in Africa and whether land reforms can be pro-poor. This paper uses unique household panel data from Tigray region in Ethiopia to assess the impact of the 1998 low-cost land registration and certification...

El problema de la posesión de la tierra en Colombia, caracterizado por la alta concentración y poco desarrollo de actividades agrícolas productivas, está marcado desde el día en que fue colonizado nuestro territorio por la corona española. Las distintas épocas que ha vivido nuestro país...

This paper presents the evolution of diverse modes of environmental management in Bulgarian agriculture, and assesses their efficiency and likely prospects of development. First, it analyzes the pace of development and the impact(s) on individual behavior of the major modes of environmental...

Sustainable agricultural practices, in as far as they rely on renewable local or farm resources, present desirable options for enhancing agricultural productivity for resource-constrained farmers in developing countries. In this paper, we used two sets of plot-level data—from a low-rainfall...

Land degradation has been one of the major areas of concern in Ethiopia. Governments and development agencies have invested substantial resources to promote land management technologies and reduce land degradation. However, there is little understanding of the impacts that land management...

Purpose – Prosperity of the agricultural sector is very crucial not only for the national economy but also for the regional development. However, this prosperity has quite often a significant environmental cost in terms of water resources overexploitation or pollution. The main purpose of this...

We investigate environmental aspects of agriculture from a welfare economic perspective and show that both positive and negative effects exhibit the character of undepletable externalities. To internalise these externalities while taking equity concerns into account, we propose compensation of...

This paper describes an adaptive agent model of rangelands based on concepts of complex adaptive systems. The behavioural and biological processes of pastoralists, regulators, livestock, grass and shrubs are modelled as well as the interactions between these components. The evolution of the...

Sustainable agriculture has become an important policy orientation in the area of land use. It serves as an analysis framework to reconcile conflicting interests. In the paper the notion of sustainable agriculture will be operationalized by using the concept of environmental utilisation space....
