Con la soja al cuello 2016 - Informe sobre agronegocios en Paraguay

Reports & Research
Novembro, 2015
Paraguay

El avance de los agronegocios se da en múltiples y diferentes dimensiones, la más visible de ellas es la ocupación del territorio. Ya los datos del año 2008 indicaban que 3% de las fincas ocupaban el 85% de la tierra, y datos actuales indican que 94.25% de las tierras cultivadas están destinadas a la producción de comodities agrícolas y solo 5.75% para la producción campesina. Esta situación tiene cada vez mayores efectos directos en la vida de toda la población paraguaya.

Global biomass production potentials exceed expected future demand without the need for cropland expansion

Peer-reviewed publication
Outubro, 2015
Global

Global biomass demand is expected to roughly double between 2005 and 2050. Current studies suggest that agricultural intensification through optimally managed crops on today's cropland alone is insufficient to satisfy future demand. In practice though, improving crop growth management through better technology and knowledge almost inevitably goes along with (1) improving farm management with increased cropping intensity and more annual harvests where feasible and (2) an economically more efficient spatial allocation of crops which maximizes farmers' profit.

The pioneers of the green revolution as forerunners of today's ecological and biotechnological revolutions

Reports & Research
Outubro, 2015
Global

This paper presents the milestones of the Green Revolution, outlining its role in the development of today's sustainable and biotechnological agriculture, as well as Romanian contribution. In order to do this we used the material found in papers and books on the research in agriculture from the 1940's to the late 1980's. Current sustainable agriculture and biotechnological advancement, including the creation of genetically modified organisms could never have been possible without the Green Revolution.

Agriculture, Forestry and Fisheries Budgetary Review and Recommendations Report

África do Sul

The Portfolio Committee’s Content Advisor provided a summary of the key financial and performance recommendations contained in the 2013/14 Budgetary Review and Recommendations Report, and described those that had been brought to the attention of the Minister of the Department of Agriculture, Forestry and Fisheries (DAFF), as well as to the Minister of Finance.

Livestock and Ecosystem Services: An Exploratory Approach to Assess Agri-Environment-Climate Payments of RDP in Trentino

Peer-reviewed publication
Setembro, 2015

The identification of an appropriate justification for Agri-Environment-Climate (AEC) payments is a crucial issue in the new Rural Development Programme (RDP). Given the environmental importance of grasslands in Trentino (Italy), the Management Authority in charge of the RDP decided to integrate an approach based on Ecosystem Services (ES) into the calculation of AEC payments. The paper presents the methodology used for this approach as well as the preliminary results. The first step entails building a probabilistic model for the ES, named Sustainable Fodder Production.

How to Make a Barranco: Modeling Erosion and Land-Use in Mediterranean Landscapes

Peer-reviewed publication
Setembro, 2015
Espanha

We use the hybrid modeling laboratory of the Mediterranean Landscape Dynamics (MedLanD) Project to simulate barranco incision in eastern Spain under different scenarios of natural and human environmental change. We carry out a series of modeling experiments set in the Rio Penaguila valley of northern Alicante Province. The MedLanD Modeling Laboratory (MML) is able to realistically simulate gullying and incision in a multi-dimensional, spatially explicit virtual landscape. We first compare erosion modeled in wooded and denuded landscapes in the absence of human land-use.

Disentangling Values in the Interrelations between Cultural Ecosystem Services and Landscape Conservation—A Case Study of the Ifugao Rice Terraces in the Philippines

Peer-reviewed publication
Setembro, 2015
Filipinas

In the past few years, there has been a growing amount of research on economic quantifications and valuations of ecosystem services (ES) in agricultural systems. However, little attention has been given to cultural ESs (CES) in general and their link to the landscape in particular. This paper tries to tackle this gap with a case study on the Ifugao Rice Terraces of the Philippines. The study aims to understand the interrelations between the different CESs and their relationships with the landscape.

Spatio-Temporal Analysis of Vegetation Dynamics in Relation to Shifting Inundation and Fire Regimes: Disentangling Environmental Variability from Land Management Decisions in a Southern African Transboundary Watershed

Peer-reviewed publication
Setembro, 2015

Increasing temperatures and wildfire incidence and decreasing precipitation and river runoff in southern Africa are predicted to have a variety of impacts on the ecology, structure, and function of semi-arid savannas, which provide innumerable livelihood resources for millions of people.

The Anatomy of Medium-Scale Farm Growth in Zambia: What Are the Implications for the Future of Smallholder Agriculture?

Peer-reviewed publication
Setembro, 2015

Lost in the debates about the appropriate scale of production to promote agricultural growth in Africa is the rapid expansion of medium-scale farmers. Using Zambia as a case study, this article explores the causes and consequences of this middle-tier transformation on the future of small-scale agriculture. Combining political economic analysis with household survey data, this article examines the relationships between the growth in medium-scale farmers and changing conditions of land access, inequality, and alienation for small-scale farmers.

Assessment of Above-Ground Biomass of Borneo Forests through a New Data-Fusion Approach Combining Two Pan-Tropical Biomass Maps

Peer-reviewed publication
Setembro, 2015
Indonésia
Brunei
Malásia

This study investigates how two existing pan-tropical above-ground biomass (AGB) maps (Saatchi 2011, Baccini 2012) can be combined to derive forest ecosystem specific carbon estimates. Several data-fusion models which combine these AGB maps according to their local correlations with independent datasets such as the spectral bands of SPOT VEGETATION imagery are analyzed. Indeed these spectral bands convey information about vegetation type and structure which can be related to biomass values. Our study area is the island of Borneo.

Modelling the Potential of Integrated Vegetation Bands (IVB) to Retain Stormwater Runoff on Steep Hillslopes of Southeast Queensland, Australia

Peer-reviewed publication
Setembro, 2015

Rainfall intensity is predicted to increase under a changing climate, leading to increased risks of hillslope erosion, downstream sedimentation and flooding. For many catchments used for grazing and agricultural land uses, it will become increasingly important to maintain ecohydrological functioning despite climatic extremes. One means to achieve this is through strategic reforestation using locally endemic species, in spatial configurations that effectively intercept, retain or and redistribute overland flows.
