“…emigration of youth population from this region (NCP, 2014). According to many studies, the younger farmers are more likely to adopt new innovations to increase efficiency level than the older ones in production (Mabe et al, 2018;Onubuogu et al, 2014). The average number of members of the interviewed households, which influence the productivity, efficiency and value of the labor force, accounts 4.5.…”

“…Under flooded conditions significant amounts of nutrients (especially nitrogen, N) may be lost by leaching and runoff during the cropping season, with important implications on water quality (Katoh et al, 2004). These processes, together with the biotic and abiotic immobilization of N (Cucu et al, 2014; and gaseous losses into the atmosphere as NH 3 , N 2 O and N 2 via volatilization and nitrification/denitrification (Cassman et al, 1998) might strongly limit plant N availability and fertilizer use efficiency, consequently affecting yields (Nie et al, 2009).…”

Favourable climate conditions and the long tradition of rice cultivation as a main source of livelihood is essential base for a large portion of the population in the Kochani valley. The low productivity levels and high production costs put major limitations on the competitiveness on markets, mainly due to inadequate and obsolete cultivation practices applied. In addition, the common cultivation methods contribute to the destruction of environment and agroecosystems by intensive use of natural resources and agrochemicals. To that end, the NCP project implemented activities for adaptation of sustainable rice practices at 30 farmers, members in the association "Rice Tiller", Cheshinovo, for the period of three years (2017-2019). Primarily, sustainable rice practices used by farmers consisted of: laser land levelling, use of certified seed material and reduced seed quantity, controlled use of fertilizers and agrochemicals and controlled use of water. Two sowing variants are implemented and tested, one by using seeding machine on dry soil and the another with manual seed broadcasting onto the watered soil. In this paper, data gained from the farmers' passports, where regularly all agrotechnical measures and costs were recorded, are processed with the use of descriptive statistics and empirical methods of analysis. The outcomes demonstrate that the introduction of sustainable rice production results in efficient use of natural resources and reduced production costs, especially with dry-seeding method, which is fundamental for mitigation of food unsafety, biodiversity loss, soil degradation and environmental pollution, and at the same time for increasing rural households' revenues.

“…La agricultura orgánica, y específicamen-te la de arroz, es un sistema de producción que busca la sostenibilidad de la tierra, especialmente en términos de conservación de la biodiversidad, y mantenimiento de la productividad (Stolton, 2002;Dermiyati & Niswati, 2014). El objetivo de este estudio fue estimar el impacto de la matriz agropecuaria (pastura y arrozal orgánico) en la diversidad florística y el carbono almacenado en bosques riparios en la zona seca del norte del Tolima, Colombia.…”

Composición florística y reservas de carbono en bosques ribereños en paisajes agropecuarios de la zona seca del Tolima, Colombia Abstract: Floristic composition and carbon stocks of riparian forests in agricultural landscapes in the dry zone of Tolima, Colombia. The tropical dry forest is a typical lowland ecosystem that is threatened by a strong seasonality and anthropogenic pressures, which can affect the forest composition and structure. The objective of this study was to estimate the impact of two agricultural matrices on the floristic composition and carbon storage in riparian forests. For this, five permanent plots (10 x 10 m each) were established and sampled in the forest interior and at the edge of two agricultural matrices (rice fields and pasture lands), in July 2013. All individuals with a diameter at breast height (dbh) ≥ 5 cm were recorded and measured, and the aboveground biomass was estimated with a general allometric model. Additionally, the importance value index (IVI), species richness and Alpha´s diversity indexes were estimated; an analysis of variance and means comparison tests of Fisher LSD were also carried out. A total of 32 families, 21 genera and 45 species (29 and 33 species in pasture lands and rice fields, respectively) of trees in 0.2 ha were recorded. The most abundant and most ecologically important species were Oxandra espintana and Calliandra sp. (520 and 241 individuals/ha and 72 and 48 % of IVI, respectively). These forests presented a mean dominance of 33.9 m 2 /ha with no effect (P < 0.05) of forest location or agricultural matrix. The matrix of the landscape did not affect (P > 0.05) the Alpha diversity indexes. The biggest trees and greatest carbon storage were found in forests with pasture matrices when compared to rice fields (14.6 vs 13.4 cm of dbh and 72.9 vs 45.6 t C/ha, respectively). This research provides an understanding of the tree richness and composition and carbon storage of riparian forests in two agricultural matrices, which could be a basis for the establishment of silvopastoral systems with native species.
