Research objective is to design an appropriated community participation process on watershed management for reduce conflicts in natural resources utilization of local community at Kon watershed, Nan province. Participatory Action Research (PAR) was applied in this form the Core Planning Team (CPT) and to arrange participatory workshop with stakeholders. The results show that the major problems at Kon watershed are unsuitable land use, forest degradation, soil erosion, and conflict on watershed resources utilization.

There is considered a problem of calculating the increase in water availability and productivity of agro-ecosystems through the use of mulching and reduced (minimum) soil tillage as well as predicting the mulching efficiency in various natural conditions. The model of heat-moisture exchange was used in the agro-ecosystems allowing the water balance dynamics in the root zone.

Objective of study were to simulate size area of land use change in Phitsanulok province from 2552 to 2560 B.E., and decided agriculture area and forest area, and to be use as a guideline map for formulating the land use and forest conservation, In Phitsanulok province. Geographic Information System couples with CLUE-S model by Logistic Regression and Markov chain model were used to predict of future land use in Phitsanulok province.

The main peculiarities of land relations abroad are highlighted in the article. Basic principles of foreign experience of land use regarding market circulation of land, concentration of major land resources by right of ownership as well as the process and ways of reformation of land relations are generalized and systematized. Some peculiarities of lease relations, collection of rents and restrictions on title to land for foreigners are analysed. Some positive aspects are distinguished in order to use them in Ukraine.

A combined agronomic and geographic approach has helped to explain forest agrosystem spatio-temporal dynamics in the forest regions of Guinea. The important expansion of cropping systems associating various perennial crops (coffee, kola, cocoa, fruit trees) and native spontaneous forest species – called “agroforests”- has been observed in 3 villages of the Kobela area. This spatial dynamic can be considered as the renewing of an ecosystem dominated in the past by forest.

In the Western region of Ukraine, melioration is both of economic and social importance. The area of reclaimed lands constitutes 2.2 million ha or 24 % of the total agricultural lands in the region. Thus, melioration is of great importance for social-economic development of agro-industrial complex of the territory. Under conditions of the land reform in Ukraine, reclaimed lands were subjected to sharing and privatization causing a negative impact on efficiency of its utilization and technical conditions of the reclaimed land infrastructure.

En la introducción se definen las características que determinan el ecosistema dehesa. En la primera parte se describen los sistemas de explotación de las distintas especies ganaderas que se han empleado tradicionalmente hasta la mitad del siglo 20. En la segunda parte se muestra la repercusión que ha tenido la investigación agraria en la revolución verde, lo que ha dado lugar a cambios drásticos en los sistemas de producción agraria. Por otra parte, se definen los pilares básicos de los modernos sistemas de explotación agraria en condiciones extensivas.

This document provides an overview on land use and spatial development in the Montpelier region and turning points the planning and governance regime. In the first part we give an overview on the land use and regional development of the case study region. In the second part, we introduce the planning system, its major actors and instruments as well as governance aspects to the reader.

The article reveals difficulties to make managerial decisions as to optimization of recreational objects’ location considering economic and technological parameters of an impact with application of fuzzy modelling. The authors propose methods of evaluation of alternative variants of managerial decision making applying programs of Mathcad with the further prospect of choosing alternatives.

The study was conducted in three watersheds (Dapo, Meja and Mizewa) in the Ethiopian part of the Blue Nile Basin to estimate the on-site cost of soil erosion using the productivity change approach, in which crop yield reduction due to plant nutrients lost with the sediment and runoff has been analysed. For this purpose, runoff measurement and sampling was conducted during the main rainy season of 2011 at the outlet of two to three sub-watersheds in each watershed. The sediment concentration of the runoff, and N and P contents in runoff and sediment were determined.
