Impact of infrastructure on profit efficiency of vegetable farming in West Java, Indonesia: stochastic frontier approach

Policy Papers & Briefs
Juin, 2014
Indonésie

Infrastructure plays an important role in increasing farm profit, since it reduces transaction costs which affect input and output price. The vegetable farming profit is relatively high although it varies, due to different infrastructure conditions. The study was conducted to analyze the level of profit efficiency due to various infrastructure conditions and to reveal the determinants of vegetable farming profit. The research was conducted in West Java, Indonesia with 192 sample farming activities.

Making the most of our land: meeting supply and demand of soil functions across spatial scales

Conference Papers & Reports
Décembre, 2015
Lettonie
Irlande

The challenges of achieving both food security and sustainability have resulted in a confluence of demands on land within the European Union: we expect our land to provide food, purify water, sequester carbon, and provide a home to biodiversity and to external nutrients. All soils perform all these five functions, but some soils ‘are better at’ supplying selective functions. Functional Land Management is a framework for policy making aimed at meeting these demands by incentivising soil management and land use practices that selectively augment specific soil functions, where required.

Long‐term declines in stream and river inorganic nitrogen (N) export correspond to forest change

Journal Articles & Books
Décembre, 2016
Suède

Human activities have exerted a powerful influence on the biogeochemical cycles of nitrogen (N) and carbon (C) and drive changes that can be a challenge to predict given the influence of multiple environmental stressors. This study focused on understanding how land management and climate change have together influenced terrestrial N storage and watershed inorganic N export across boreal and sub‐arctic landscapes in northern Sweden.

evolution of agrarian practices and its effects on the structure of enclosure landscapes in the Alt Empordà (Catalonia, Spain), 1957-2001

Europe

During the last 50 years, mechanisation of the rural environment, and, more recently, the Common Agricultural Policy have led to profound changes in agrarian landscapes throughout Europe, and in particular in the rich and diverse Mediterranean landscapes (). In the north-east of the Iberian Peninsula, a small area of hedgerow landscape persists as a remnant of what was once an important centre for livestock production.

Impact of pigeon pea biochar on cadmium mobility in soil and transfer rate to leafy vegetable spinach

Journal Articles & Books
Décembre, 2016

Introduction of heavy metals in the environment by various anthropogenic activities has become a potential treat to life. Among the heavy metals, cadmium (Cd) shows relatively high soil mobility and has high phyto-mammalian toxicity. Integration of soil remediation and ecosystem services, such as carbon sequestration in soils through organic amendments, may provide an attractive land management option for contaminated sites.

When peer-reviewed publications are not enough! Delivering science for natural resource management

Journal Articles & Books
Décembre, 2012

Over the last century, natural resource management on forest lands has shifted from a singular focus on resource extraction to many foci, such as recreation, tourism, conservation, view-scapes, cultural and spiritual values, sustainability, and other values. As a result, the information needs of land managers must now include social and cultural values. In addition, the public's interest in having greater participation in land management decisions and in generating scientific knowledge has never been greater.

Changes in soil properties following conversion of Acacia senegal plantation to other land management systems in North Kordofan State, Sudan

Décembre, 2009
Soudan

Changes in soil texture, bulk density, pH, concentrations and stocks of OC, N, P and K before and after conversion of a 6-year-old Acacia senegal plantation to other land management systems (LMS) were investigated, after three cropping seasons, in the drylands of western Sudan. LMS included pure and intercropped sorghum (PS), roselle (PR) and grasses (PG) with A. senegal at high- and low-tree densities (HD 433 and LD 266 trees ha-1).

Alternative practices for sediment and nutrient loss control on livestock farms in northeast Iowa

Journal Articles & Books
Décembre, 2006

A number of structural and managerial practices were evaluated to determine their environmental and economic effectiveness on animal feeding operations in the upper Maquoketa river watershed in northeast Iowa. Economic and environmental model simulations were performed over a 30-year time horizon for each of these practices using extensive data collected from the study area.

Partitioning of applied ¹⁵N fertilizer in a longleaf pine and native woody ornamental intercropping system

Journal Articles & Books
Décembre, 2010

The cultivation of ornamentals to produce woody floral products—the fresh or dried stems that are used for decorative purposes—may be an attractive option for southeastern landowners looking to generate income from small landholdings. Since many shrubs native to the understory of the longleaf pine (Pinus palustris Mill.) ecosystem have market potential, one possibility is the intercropping of select species in the between-row spacing of young longleaf pine plantations.

Fuels and fire behavior dynamics in bark beetle-attacked forests in Western North America and implications for fire management

Journal Articles & Books
Décembre, 2012

Declining forest health attributed to associations between extensive bark beetle-caused tree mortality, accumulations of hazardous fuels, wildfire, and climate change have catalyzed changes in forest health and wildfire protection policies of land management agencies. These changes subsequently prompted research to investigate the extent to which bark beetle-altered fuel complexes affect fire behavior.
